The Evolving Role of Precision Surgery in Gynecologic Cancers

Dr. Ebony Hoskins and Dr. Andreas Obermair discuss the surgical management of gynecologic cancers, including the role of minimally invasive surgery, approaches in fertility preservation, and the nuances of surgical debulking. TRANSCRIPT Dr. Ebony Hoskins: Hello and welcome to the ASCO Daily News Podcast, I'm Dr. Ebony Hoskins. I'm a gynecologic oncologist at MedStar Washington Hospital Center in Washington, DC, and your guest host of the ASCO Daily News Podcast. Today we'll be discussing the surgical management of gynecologic cancer, including the role of minimally invasive surgery (MIS), approaches in fertility preservation, and the nuances of surgical debulking, timing, and its impact on outcomes. I am delighted to welcome Dr. Andreas Obermair for today's discussion. Dr. Obermair is an internationally renowned gynecologic oncologist, a professor of gynecologic oncology at the University of Queensland, and the head of the Queensland Center for Gynecologic Cancer Research. Our full disclosures are available in the transcript of this episode. Dr. Obermair, it's great speaking with you today. Dr. Andreas Obermair: Thank you so much for inviting me to this podcast. Dr. Ebony Hoskins: I am very excited. I looked at your paper and I thought, gosh, is everything surgical? This is everything that I deal with daily in terms of cancer in counseling patients. What prompted this review regarding GYN cancer management? Dr. Andreas Obermair: Yes, our article was published in the ASCO Educational Book; it is volume 44 in 2024. And this article covers some key aspects of targeted precision surgical management principles in endometrial cancer, cervical cancer, and ovarian cancer. While surgery is considered the cornerstone of gynecologic cancer treatment, sometimes research doesn't necessarily reflect that. And so I think ASCO asked us to; so it was not just me, there was a team of colleagues from different parts of the United States and Australia to reflect on surgical aspects of gynecologic cancer care and I feel super passionate about that because I do believe that surgery has a lot to offer. Surgical interventions need to be defined and overall, I see the research that I'm doing as part of my daily job to go towards precision surgery. And I think that is, well, that is something that I'm increasingly passionate for. Dr. Ebony Hoskins: Well, I think we should get into it. One thing that comes to mind is the innovation of minimally invasive surgery in endometrial cancer. I always reflect on when I started my fellowship, I guess it's been about 15 years ago, all of our endometrial cancer patients had a midline vertical incision, increased risk of abscess, infections and a long hospital stay. Do you mind commenting on how you see management of endometrial cancer today? Dr. Andreas Obermair: Thank you very much for giving the historical perspective because the generation of gynecologic oncologists today, they may not even know what we dealt with, what problems we had to solve. So like you, when I was a fellow in gynecologic oncology, we did midline or lower crosswise incisions, the length of stay was, five days, seven days, but we had patients in hospital because of complications for 28 days. We took them back to the operating theaters because those are patients with a BMI of 40 plus, 45, 50 and so forth. So we really needed to solve problems. And then I was exposed to a mentor who taught minimal invasive surgery. And in Australia he was one of the first ones who embarked on that. And I can remember, I was mesmerized by this operation, like not only how logical this procedure was, but also we did rounds afterwards. And I saw these women after surgery and I saw them sitting upright, lipstick on, having had a full meal at the end of the day. And I thought, wow, this is the most rewarding experience that I have to round these patients after surgery. And so I was thinking, how could I help to establish this operation as standard? Like a standard that other people would accept this is better. And so I thought we needed to do a trial on this. And then it took a long time. It took a long time to get the support for the [LACE - Laparoscopic Approach to Cancer of the Endometrium] trial. And in this context, I just also wanted to remind us all that there were concerns about minimal invasive surgery in endometrial cancer at the time. So for example, one of the concerns was when I submitted my grant funding applications, people said, "Well, even if we fund you, wouldn't be able to do this trial because there are actually no surgeons who actually do minimally invasive surgery." And at the time, for example, in Australia, there were maybe five people, a handful of people who were able to do this operation, right? This was about 20 years ago. The other concern people had was they were saying, could minimally invasive surgery for endometrial cancer, could that cause port side metastasis because there were case reports. So there were a lot of things that we didn't know anyway. We did this trial and I'm super happy we did this trial. We started in 2005, and it took five years to enroll. At the same time, GOG LAP2 was ramping up and the LACE trial and GOG LAP2 then got published and provided the foundations for minimally invasive surgery in endometrial cancer. I'm super happy that we have randomized data about that because now when we go back and now when people have concerns about this, should we do minimally invasive surgery in P53 mutant tumors, I'm saying, well, we actually have data on that. We could go back, we could actually do more research on that if we wanted to, but our treatment recommendations are standing on solid feet. Dr. Ebony Hoskins: Well, my patients are thankful. I see patients all the time and they have high risk and morbidly obese, lots of medical issues and actually I send them home most the same day. And I think, you know, I'm very appreciative of that research, because we obviously practice evidence-based and it's certainly a game changer. Let's go along the lines of MIS and cervical cancer. And this is going back to the LACC [Laparoscopic Approach to Cervical Cancer] trial. I remember, again, one of these early adopters of use of robotic surgery and laparoscopic surgery for radical hysterectomy and thought it was so cool. You know, we can see all the anatomy well and then have the data to show that we actually had a decreased survival. And I even see that most recent updated data just showing it still continued. Can you talk a little bit about why you think there is a difference? I know there's ongoing trials, but still interested in kind of why do you think there's a survival difference? Dr. Andreas Obermair: So Ebony, I hope you don't mind me going back a step. So the LACC study was developed from the LACE trial. So we thought we wanted to reproduce the LACE data/LAP2 data. We wanted to reproduce that in cervix cancer. And people were saying, why do you do that? Like, why would that be different in any way? We recognize that minimally invasive radical hysterectomy is not a standard. We're not going to enroll patients in a randomized trial where we open and do a laparotomy on half the patients. So I think the lesson that really needs to be learned here is that any surgical intervention that we do, we should put on good evidence footing because otherwise we're really running the risk of jeopardizing patients' outcomes. So, that was number one and LACC started two years after LACE started. So LACC started in 2007, and I just wanted to acknowledge the LACC principal investigator, Dr. Pedro Ramirez, who at the time worked at MD Anderson. And we incidentally realized that we had a common interest. The findings came totally unexpected and came as an utter shock to both of us. We did not expect this. We expected to see very similar disease-free and overall survival data as we saw in the endometrial cancer cohort. Now LACC was not designed to check why there was a difference in disease-free survival. So this is very important to understand. We did not expect it. Like, so there was no point checking why that is the case. My personal idea, and I think it is fair enough if we share personal ideas, and this is not even a hypothesis I want to say, this is just a personal idea is that in endometrial cancer, we're dealing with a tumor where most of the time the cancer is surrounded by a myometrial shell. And most of the time the cancer would not get into outside contact with the peritoneal cavity. Whereas in cervix cancer, this is very different because in cervix cancer, we need to manipulate the cervix and the tumor is right at the outside there. So I personally don't use a uterine manipulator. I believe in the United States, uterine manipulators are used all the time. My experience is not in this area, so I can't comment on that. But I would think that the manipulation of the cervix and the contact of the cervix to the free peritoneal cavity could be one of the reasons. But again, this is simply a personal opinion. Dr. Ebony Hoskins: Well, I appreciate it. Dr. Andreas Obermair: Ebony at the end of the day, right, medicine is empirical science, and empirical science means that we just make observations, we make observations, we measure them, and we pass them on. And we made an observation. And, and while we're saying that, and yes, you're absolutely right, the final [LACC] reports were published in JCO recently. And I'm very grateful to the JCO editorial team that they accepted the paper, and they communicated the results because this is obviously very important. At the same time, I would like to say that there are now three or four RCTs that challenge the LACC data. These RCTs are ongoing, and a lot of people will be looking forward to having these results available. Dr. Ebony Hoskins: Very good. In early-stage cervical cancer, the SHAPE trial looked at simple ve

Botensilimab Plus Balstilimab in Advanced Sarcomas

Dr. Shannon Westin and her guest, Dr. Breelyn Wilky, discuss the JCO article, ""Botensilimab (Fc-enhanced anti-cytotoxic lymphocyte-association protein-4 antibody) Plus Balstilimab (anti-PD-1 antibody) in Patients With Relapsed/Refractory Metastatic Sarcomas." TRANSCRIPT Shannon Westin: Hello, everyone, and welcome to another episode of JCO After Hours, the podcast where we get in depth on research that has been published in the Journal of Clinical Oncology. I am your host, Gynecologic Oncologist and Social Media Consultant Editor of the JCO, Shannon Westin. I serve here from the University of Texas MD Anderson Cancer Center. And I am so excited to welcome Dr. Breelyn Wilky. She's an Associate Professor and the Director of Sarcoma Medical Oncology in the Department of Medicine Division of Medical Oncology, and the Cheryl Bennett & McNeilly family endowed chair in Sarcoma Research, the Deputy Associate Director of Clinical research at the University of Colorado Cancer Center. Welcome. Dr. Breelyn Wilky: Thank you so much. I'm delighted to be here. Shannon Westin: And with all those titles, I'm super impressed that she was able to complete the manuscript that we're going to discuss today, which is "Botensilimab (Fc-enhanced anti-cytotoxic lymphocyte-association protein-4 antibody) Plus Balstilimab (anti-PD-1 antibody) in Patients With Relapsed/Refractory Metastatic Sarcomas." And this was published in the JCO on January 27, 2025. And please note, our participants do not have any conflicts of interest. So this is exciting. Let's first level set. Can you review with us just the current state of sarcoma incidents, survival outcomes, that kind of thing so we all know where we're starting? Dr. Breelyn Wilky: Yes. So, you know, sarcomas are really, I like to call them the black box cancer type. And the big thing is that there's really more than a hundred different kinds of sarcomas, which collectively altogether make up only 1% of adult cancers. And so we talk about these as being bone and soft tissue tumors, but really, the heterogeneity is just incredible. You're talking maybe 10,000 to 12,000 new cases of soft tissue sarcoma per year, which is pretty rare in the grand scheme of things. And the trouble with these is that while you can cure sarcomas if you find them early and they're localized, when they metastasize and spread and are not resectable, we're looking at median overall survivals of really only 12 to 18 months, even, you know, with our best therapies that we have. So, really there's just a dire need for new treatments for this really tough group of diseases. Shannon Westin: Yeah, I agree. I'm a gynecologic oncologist, and we have our little subset of sarcomas that I know there's a little bit out of every one. So I'm really excited to pull this manuscript as one of our podcasts offerings because I think we're all seeing these patients in the clinic and certainly our listeners that have sarcoma or have family members with sarcoma, this is so good to have a real focus on a rare group of tumors that have been a little bit lumped together. Now, with that being said, I know this is such a heterogeneous population, but can you briefly overview a little bit around the standard of care for treatment of recurrent sarcomas? Dr. Breelyn Wilky: We have actually been using the same drugs really since about the 1970s, and up until very recently, nothing had really challenged doxorubicin, the old 'red devil', like we used to call it. And this has been the mainstay of treatment for metastatic sarcomas and really used across the board. In the GYN literature, for uterine leiomyosarcoma, we did see some promising activity with the combination of doxorubicin and trabectedin coming out of the French group. But, except for that study, no combination therapy or new drug has been proven better in terms of overall survival compared to doxorubicin monotherapy, really over 40, 50 years. So it's definitely a tough situation. Now, we do have other drugs that we use, so most patients will wind up getting doxorubicin-based therapy. There's a couple of other regimens that we'll reach to, like gemcitabine docetaxel. And once you get into the specific subtypes, we have some approvals in liposarcomas and leiomyosarcomas for some other drugs. But really the median progression for survival for most of these regimens is somewhere four to six months. And response rates typically are somewhere like 10%, 15% for most of these. So it's really just a very tough field and a tough group of patients to try to make an impact for. Shannon Westin: So let's talk a little bit more kind of getting focused on what you've studied here. What's been the role of immunotherapy thus far in the treatment of sarcomas maybe prior to this particular study? Dr. Breelyn Wilky: Clearly, we all know that immune therapy has just changed cancer care forever over the last few years for so many different types of cancers and diseases like melanoma and renal cell and lung cancer have just been transformed by checkpoint inhibitors specifically directed against PD-1 or CTLA-4 or both. And so, of course, you know, sarcoma docs we're super excited to try to see if these might potentially have activity in our tumors as well. I never had seen myself in my career getting into immunotherapy until I was able to run an investigator-initiated study during my role in Miami, where we combined pembrolizumab, so PD-1 inhibitor, with axitinib which was a pan-VEGF inhibitor. And lo and behold, like I had patients that I was seeing responses when other treatments, all those chemotherapies I was just talking about had failed. And one of my first patients I treated was about a 60-year-old lady with something called cutaneous angiosarcoma. So this is a blood vessel sarcoma all over her face. And we had treated her with 10 different therapies, all the chemotherapy regimens, targeted therapies, clinical trials, and nothing was working. But I put her on a phase 1 trial with a baby dose of CTLA-4 and this woman had a complete response. And so for me, once I saw it work in even just those couple of patients, like that was nothing that we'd ever seen with our chemotherapy regimens. And so that sort of shifted my career towards really focusing on this, and this is about the time where some of the studies started to come out for sarcomas. And the take home with sarcoma is about 20% of sarcomas have this sort of immune hot physiology. So what that basically means is if you look at gene expression of immune related gene signatures, or you look for infiltrating T-cells, sort of the SWAT team of our immune system, like you can find those in the tumors. And it's sort of evidence that the immune system had some clue for that 20% of patients that this was a foreign tumor and that it should be attacking it and maybe just needed a little help. But globally, about 80% of sarcomas are these immune cold tumors, which means the immune system has no clue that these things are even a threat. And there's almost no immune activation, very, very few antigens. In other cancer types, high neoantigens or tumor antigens help the immune system work better. And so that basically goes with what we've seen with trials of PD-1 or CTLA-4 blockade. About 20% of sarcomas, with some exceptions, can respond. But really 80% across the board, you're stuck, you just can't get them to be recognized. And so that's where I think this data is so interesting is there's some signals of activity in these immune cold tumors which, at least historically with the trials we've done so far, we really haven't seen that with sort of the traditional checkpoints. Shannon Westin: So I think now this is a great time to maybe talk about the study design in general, the eligibility and just give us kind of a run through of that. Dr. Breelyn Wilky: So this trial was a phase 1 trial of a drug called botensilimab, which is a next generation CTLA-4 directed immune modulator. So what makes botensilimab different is that the CTLA-4 end is very similar to other CTLA-4 inhibitors that are out there, but it's been engineered on the back end of the molecule that binds to Fc gamma receptors to basically bind tighter with higher affinity. And what this translates to in laboratory models and increasingly now in patients is it does a better job of priming, of educating our T cells, our, again, these highly intelligent antigen specific cells, but also natural killer cells. It does a better job of sort of educating those. It helps to activate macrophages and other supporting actors in the immune response. And so the idea here is that there's evidence that botensilimab may do a better job at creating new responses in immune cold tumors. The study combined either botensilimab as monotherapy or in combination with a PD-1 inhibitor called balstilimab. And this was all comers, really a variety of tumor types. And to date I think we're close to about 500 patients with a variety of solid tumors that have been accrued to this study, this C-800-01 phase 1 trial. This paper reports on the sarcoma patients that were enrolled as part of this study. And so, again, given what I've told you about sarcomas being really immune cold, we were just so excited to have the opportunity to enroll on a next generation immune therapy for these tumors that really we were running into roadblocks trying to use immunotherapy previously. Shannon Westin: It's a very compelling idea and I'm so excited for you to tell people what you found. I think first things first, it was an early phase trial. So why don't we talk a little bit about the safety of the regimen. Was there anything that you didn't expect? Dr. Breelyn Wilky: Right. So similar to other checkpoint inhibitors, you know, the idea is that these drugs can cause immune mediated toxicities, right? So essentially you're revving up the immune system and it can sometimes get a bit confused and start attacking our

JCO Article Insights: Long-Term Outcome of Neoadjuvant Chemotherapy for Rectal Cancer

In this JCO Article Insights episode, Peter Li summarizes "Neoadjuvant Modified Infusional Fluorouracil, Leucovorin, and Oxaliplatin With or Without Radiation Versus Fluorouracil Plus Radiation for Locally Advanced Rectal Cancer: Updated Results of the FOWARC Study After a Median Follow-Up of 10 Years," by Dr. Jianwei Zhang et al. published on December 13, 2024. TRANSCRIPT Peter Li: Hello and welcome to the JCO Article Insights. I'm your host Peter Li and today we will be discussing the Journal of Clinical Oncology article, "Neoadjuvant Modified Infusional Fluorouracil, Leucovorin, and Oxaliplatin With or Without Radiation Versus Fluorouracil Plus Radiation for Locally Advanced Rectal Cancer: Updated Results of the FOWARC Study After a Median Follow-Up of 10 Years," by Dr. Jianwei Zhang et al. For a reminder to the audience, the FOWARC study is a Chinese-based study that looked into the treatment of locally advanced rectal cancers with neoadjuvant chemotherapy based regimens with or without radiation. This study was first published back in 2019 where the three-year data showed no difference in three-year disease-free survival over survival between the three study arms. As a reminder of what those arms were, there were one historical control and two interventional arms. The control arm used 5-FU with radiation therapy with five cycles of 5-fluorouracil with radiation during cycles two to four followed by surgery and then seven cycles adjuvantly. Their first interventional arm was the same as the control arm with the addition of oxaliplatin on day 1of each cycle. And lastly, the third arm was FOLFOX only for four to six cycles followed by surgery and then six to eight cycles adjuvantly completing about a total of 12 weeks of chemotherapy. They recruited about 495 patients with 165 patients randomized to each arm. They were relatively well balanced by age, clinical staging and distance from the anal verge. Median age was about mid-50s with a slight male predominance and patients were primarily stage 3 with 20% to 30% being stage 2. About 30% had clinical T4 disease and about 25% had clinical N2 disease. Median follow up time was 122.5 months or 10 years and their follow up endpoints were disease-free survival, overall survival and local recurrence, and they also performed subgroup analyses based on post surgical pathological staging. Survival was analyzed using Kaplan-Meier method with a significant threshold of p being less than 0.05. About 451 patients actually underwent surgery, which is about 91% of patients. The main reason for not going through surgery was due to refusal but one was due to toxicity and two were due to disease progression in the control arm. Follow up loss rate was about 10% in each group. Now looking at their primary endpoints in their initial study, local recurrence was about 8.8% in the control arm versus 7.9% in the FOLFOX radiation group versus 9.2% in the FOLFOX only group. Distant metastasis was about 30% in each arm and the sites of metastases were primarily in the lung and liver. Now, following up with 10 years, there were only three new events in the chemoradiation group with local recurrence happening at 10.8% in the control arm versus 8% in the FOLFOX RT group versus 9.6% in the chemo only group. These findings were not statistically significant. In their subgroup analysis by pathological staging, they found that pathological CR or complete response had a lower rate of local recurrence compared to those with increasing pathological staging coming in at 3% versus 4.3% versus 11.6% versus 15.8% in pCR versus Stage 1, 2, 3 respectively. And they found no difference in each stage with each interventional arm. Looking at long term survival their 10-year disease free survival showed 52.5% in the 5-FU radiation group versus 62.6% in the FOLFOX RT group versus 60.5% in the chemotherapy only group with no statistically significant difference between three groups. By pathological staging, they found improved 10-year disease survival in those who achieved pathological complete response versus those who did not with 84.3% in the pCR group versus 78.7% versus 56.8% versus 27.7% in the stage 1 versus 2 versus 3 group. And again they found no statistical significance difference between each arm. Now looking at the 10-year overall survival rates between the three arms, in the control arm the 10-year overall survival was 65.9% versus 72.3% in the FOLFOX RT group versus 73.4% in the chemo only group. By pathological stage, again, they showed a statistically significant difference in those who achieved pCR versus those who had pathological stage 1 to 3 disease with overall survival being 92.4% in those who achieved pCR versus 84.9% versus 68.6% versus 48.8% in stage 1, 2, 3 respectively. Now in the discussion, authors mentioned that with a median follow up of 10 years, FOLFOX alone had similar disease-free survival, local recurrence and distant metastasis and overall survival compared to those who received neoadjuvant chemoradiation, justifying the omission of radiation without compromising results or outcomes for each patient. There were no differences in subgroup analysis for disease free survival local recurrence or overall survival based on pathological staging. There were only three new events compared to the last follow up, with local recurrence happening only in the chemo radiation groups. Local recurrence rates at 10 years was about 10%. Compared to other clinical trials such as CAO, ARO or AIO-94, the rate of local recurrence was similar to those historical trials. The authors also compared their findings to the PROSPECT study which looks at the use of total neoadjuvant chemo radiation versus chemotherapy alone, which boasted only about a 2% local recurrence rate. But as a reminder, high risk locally advanced rectal cancers were excluded, mainly those with T4 or N2 disease, which may explain the difference in terms of local recurrence in the PROSPECT versus this study. Another finding is that pathological complete responses are also an important prognostic marker with lower 10-year local recurrence rate, disease-free survival and overall survival with worse outcomes with increased pathological staging. Distant metastasis rates were still at 30%, with the most common site being lung then liver then lymph nodes consistent with other historical studies. Chemotherapy seemed to be better at reducing liver mets than lung metastasis per their findings. In their post hoc analysis of their own study, chemo radiation was also associated with higher incidence of low anterior resection syndrome and persistent ostomy compared to chemotherapy alone, meaning that they had better quality of life with the chemotherapy only approach. In conclusion, a chemotherapy only approach can be safe and a feasible treatment for locally advanced rectal cancer without compromising outcomes. Omission of radiation may reduce the risk of overtreatment and improve quality of life for some of these patients. However, this does not necessarily exclude the role of radiation as it may still play a role in a response escalation approach for those who do not respond to chemotherapy alone.

JCO PO Article Insights: Publication Trends in JCO Precision Oncology

In this JCO Precision Oncology Article Insights episode, Miki Horiguchi summarizes an editorial: "Expanding the Reach of Personalized Medicine in Cancer Care: Current Progress and Future Directions of JCO Precision Oncology" by Dr. Yushu Shi et al. published on May 30, 2024. TRANSCRIPT Hello and welcome to JCO Precision Oncology Article Insights. I'm your host Miki Horiguchi, an ASCO Journals Editorial Fellow. Today, I will be providing a summary of the article titled "Expanding the Reach of Personalized Medicine in Cancer Care: Current Progress and Future Directions of JCO Precision Oncology". This is an editorial by Dr. Yushu Shi and colleagues that investigated trends in publication, peer review, and global influence of JCO precision oncology. Before getting into the editorial, I would like to briefly introduce to precision oncology and the JCO Precision Oncology journal as a leading platform for research in this field. Precision oncology is a personalized medicine approach that leverages advances in genomics and molecular profiling of tumors, biomarker-driven decisions, and targeted therapies to enhance clinical care for patients with various cancer types. Since there are many aspects to consider, such as biologic, clinical, and statistical aspects, advances in precision oncology also come with numerous challenges. These include identifying targetable mutations and addressing tumor heterogeneity and drug resistance. Other challenges are developing new study designs and statistical analysis methods to evaluate new approaches, as well as developing methods to manage large and complex datasets. Since the American Society of Clinical Oncology introduced the journal JCO Precision Oncology (or JCO PO) in 2016, it has played an important role as a dedicated platform for publishing high-quality research and promoting discussions on those challenges. JCO PO is a peer-reviewed, online-only, article-based journal publishing articles across multiple categories. These include original reports, case reports, review articles, commentaries, correspondence, editorials, special articles, and molecular tumor board case discussions. The journal's contribution to the advancement of the field is reflected in the journals' impact factor, which was 4.6 in 2022 and 5.3 in 2023. In the editorial, Dr. Shi and colleagues first investigated the publication trends from 2017 to 2022, highlighting cancer types, article types, the number of citations, and topics of papers published in JCO PO that have had broad impact. The papers accepted at JCO PO covered a broad range of research topics, including genomics-driven tumor treatments, molecularly selected targeted therapy, translational oncology, cancer biomarkers, gene expression and profiling, biostatistics and clinical trial methodology, epidemiology, and cancer prevention and control. The most common cancer types are thoracic, GI, and breast cancers. Original reports were more likely to be cited than case reports. The average number of annual citations for original reports was 4.33, while it was 1.39 for case reports. The authors listed the 10 most cited papers published in JCO PO in a table. The most cited paper was an original report titled "Landscape of Microsatellite Instability Across 39 Cancer Types" by Bonneville and colleagues. The paper has been cited more than 600 times since it was published in 2017. Next, the authors conducted an analysis to see trends in peer-review. When manuscripts are submitted to JCO PO, they go through a rigorous peer-review process. Reviewers evaluate them based on five key metrics: importance of the study, originality, quality of writing, relevance to clinical practice, and scientific strength. Each metric is rated on a scale from 1 to 5, with higher scores indicating better performance. Dr. Shi and colleagues compared the rating scores between accepted and rejected manuscripts of original reports and case reports. They found that the median score of accepted manuscripts was above 3.5 for all metrics. The findings highlight that no single metric determines acceptance, underscoring the importance of excelling in all five areas when developing manuscripts. Finally, the authors looked at trends in global influence in JCO PO. Counting the country where the corresponding author's institution is located, Dr. Shi and colleagues found that JCO PO has accepted manuscripts from 36 countries, indicating a steady increase in its global reach. The United States accounts for about 71% of the total contributors. The other top contributors include France, Canada, Italy, Australia, the Netherlands, Germany, Japan, the United Kingdom and China. Notably, global collaborations among authors have significantly increased, with the proportion of papers from multiple countries more than doubling from 12.5% in 2016 to 26.5% in 2022. These facts reflect JCO PO's ongoing commitment to engaging with the international precision oncology community and encouraging global research submissions. At the end of the editorial, the authors provided some guidance for future authors. Across original reports and case reports, successful submissions to JCO PO typically have a translational focus. They provided a mechanistic understanding of tumor biology and utilized cancer genomics to inform clinical decision making. The authors also highlighted several underrepresented but growing areas of interest at JCO PO. These include pediatric oncology, sarcomas, ethics, trial methodology, informatics, computational approaches, and statistical methods related to precision oncology. Furthermore, the increasing significance of germline genetics, pharmacogenetics, molecular diagnostics, and molecular epidemiology in precision oncology has been recognized and valued by JCO PO. JCO PO also has special series issues. The special series feature timely research topics, such as Equity in Precision Medicine, Statistical Methods for Precision Oncology, and Next Generation Sequencing. Through these special series, JCO PO continues to lead the advancement of the application of precision oncology across a diverse patient population. The authors also provided points to consider when submitting case reports. For successful case report submissions, especially n-of-1 reports that showcase novel findings with potential clinical impact, it is crucial to include robust data to support the clinical observations, investigate underlying mechanisms, and ensure proper protection of patients' identity and autonomy. An n-of-1 report alone is often insufficient for publication.

JCO Article Insights: IMS-IMWG Consensus on High-Risk Multiple Myeloma

In this JCO Article Insights episode, Michael Hughes summarizes "International Myeloma Society and International Myeloma Working Group Consensus Recommendations on the Definition of High-Risk Multiple Myeloma" by Avet-Loiseau et al. published on June 09, 2025 along with an interview with author Dr Nikhil C. Munshi, MD. TRANSCRIPT Michael Hughes: Welcome to this episode of JCO Article Insights. This is Michael Hughes, JCO's editorial fellow. Today I am interviewing Dr. Nikhil Munshi on the "International Myeloma Society and International Myeloma Working Group Consensus Recommendations on the Definition of High-Risk Multiple Myeloma" by Avet-Loiseau et al. At the time of this recording, our guest has disclosures that will be linked in the transcript. While some patients with multiple myeloma live for decades after treatment, others exhibit refractory or rapidly relapsing disease irrespective of treatment administered. We term this "high-risk myeloma." Multiple risk stratification systems have been created, starting with the Durie-Salmon system in 1975 and evolving with the advent of novel therapeutics and novel treatment approaches. In 2015, the Revised International Staging System (R-ISS) was introduced, which incorporated novel clinical and cytogenetic markers and remained, until recently, a mainstay of risk stratification in newly diagnosed disease. Myeloma as a field has, just in the past few years, though, undergone explosive changes. In particular, we have seen groundbreaking advances not only in treatments - the introduction of anti-CD38 agents and the advent of cellular and bispecific therapies - but also in diagnostic technology and our understanding of the genetic lesions in myeloma. This has led to the proliferation of numerous trials employing different definitions of high-risk myeloma, a burgeoning problem for patients and providers alike, and has prompted attempts to consolidate definitions and terminology. Regarding cytogenetic lesions, at least, Kaiser et al's federated meta-analysis of 24 therapeutic trials, published here in the JCO in February of 2025 and recently podcasted in an interview with associate editor Dr. Suzanne Lentzsch, posited a new cytogenetic classification system to realize a shared platform upon which we might contextualize those trial results. This article we have here by Dr. Avet-Loiseau, Dr. Munshi, and colleagues, published online in early June of this year and hot off the presses, is the definitive joint statement from the International Myeloma Society (IMS) and the International Myeloma Working Group (IMWG). What is high-risk multiple myeloma for the modern era? The IMS and IMWG Genomics Workshop was held in July 2023 and was attended by international myeloma experts, collaborating to reach consensus based on large volumes of data presented and shared. The datasets included cohorts from the Intergroupe Francophone du Myélome (IFM); the HARMONY project, comprised of multiple European academic trials; the FORTE study, findings from which solidified KRd as a viable induction regimen; the Grupo Español de Mieloma Múltiple (GEM) and the PETHEMA Foundation; the German-Speaking Myeloma Multicenter Group (GMMG); the UK-based Myeloma XI, findings from which confirmed the concept of lenalidomide maintenance; Emory 1000, a large, real-world dataset from Emory University in Atlanta; the Multiple Myeloma Research Foundation Clinical Outcomes in Multiple Myeloma to Personal Assessment of Genetic Profile (CoMMpass) dataset; and some newly diagnosed myeloma cohorts from the Mayo Clinic. Data were not pooled for analyses and were assessed individually - that is to say, with clear a priori understanding of whence the data had been gathered and for what original purposes. Consensus on topics was developed based on the preponderance of data across studies and cohorts. In terms of results, substantial revisions were made to the genomic staging of high-risk multiple myeloma, and these can be sorted into three major categories: A) alterations to the tumor suppressor gene TP53; B) translocations involving chromosome 14: t(14;16) (c-MAF overexpression), t(14;20) (MAFB overexpression), and t(4;14) (NSD2 overexpression); and C) chromosome 1 abnormalities: deletions of 1p or additional copies of 1q. In terms of category A, TP53 alterations: Deletion of 17p is present in up to 10% of patients at diagnosis and is enriched in relapsed or refractory disease. This is well-documented as a high-risk feature, but the proportion of the myeloma cells with deletion 17p actually impacts prognosis. GEM and HARMONY data analyses confirmed the use of 20% clonal cell fraction as the optimal threshold value for high-risk disease. That is to say, there must be the deletion of 17p in at least 20% of the myeloma cells on a FISH-analysis of a CD138-enriched bone marrow sample to qualify as high-risk disease. TP53 mutations can also occur. Inactivating mutations appear to have deleterious effects similar to chromosomal losses, and the biallelic loss of TP53, however it occurs, portends particularly poor prognosis. This effect is seen across Myeloma XI, CoMMpass, and IFM cohorts. Biallelic loss is rare, it appears to occur in only about 5% of patients, but next-generation sequencing is nevertheless recommended in all myeloma patients. Category B, chromosome 14 translocations: Translocation t(14;16) occurs in about 2% to 3% of patients with newly diagnosed disease. In the available data, primarily real-world IFM data, t(14;16) almost always occurs with chromosome 1 abnormalities. Translocation t(4;14) occurs in about 10% to 12% of newly diagnosed disease, but only patients with specific NSD2 alterations are, in fact, at risk of worse prognosis, which clinically appears to be about one in every three of those patients. And so together, the CoMMpass and Myeloma XI data suggest that translocation t(4;14) only in combination with deletion 1p or gain or amplification of 1q correlates with worse prognosis. Translocation t(14;20) occurs in only 2% of newly diagnosed disease. Similar to translocation t(4;14), it doesn't appear to have an effect on prognosis, except if the translocation co-occurs with chromosome 1 lesions, in which case patients do fare worse. Overall, these three translocations - t(14;16), t(4;14), and t(14;20) - should be considered high-risk only if chromosome 1 aberrations are also present. In terms of those chromosome 1 aberrations, category C, first deletions of 1p: Occurring in about 13% to 15% of newly diagnosed disease, deletion 1p eliminates critical cell checkpoints and normal apoptotic signaling. In the IFM and CoMMpass dataset analyses, biallelic deletion of 1p and monoallelic deletion of 1p co-occurring with additional copies of 1q denote high-risk. In terms of the other aberration in chromosome 1 possible in myeloma, gain or amplification of 1q: This occurs in up to 35% to 37% of newly diagnosed disease. It upregulates CKS1B, which is a cyclin-dependent kinase, and ANP32E, a histone acetyltransferase inhibitor. GEM and IFM data suggest that gain or amplification of 1q - there was no clear survival detriment to amplification - is best considered as a high-risk feature only in combination with the other risk factors as above. Now, in terms of any other criteria for high-risk disease, there remains one other item, and that has to do with tumor burden. There has been a consensus shift, really, in both the IMS and IMWG to attempt to develop a definition of high-risk disease which is based on biologic features rather than empirically observed and potentially temporally dynamic features, such as lactate dehydrogenase. Beta-2 microglobulin remains an independent high-risk indicator, but care must be taken when measuring it, as renal dysfunction can artificially inflate peripheral titers. The consensus conclusion was that a beta-2 microglobulin of at least 5.5 without renal failure should be considered high-risk but should not preclude detailed genomic profiling. So, in conclusion, the novel 2025 IMS-IMWG risk stratification system for myeloma is binary. It's either high-risk disease or standard-risk disease. It's got four criteria. Number one, deletion 17p and/or a TP53 mutation. Clonal cell fraction cut-off, remember, is 20%. Or number two, an IGH translocation - t(4;14), t(14;16), t(14;20) - with 1q gain and/or deletion of 1p. Or a monoallelic deletion of 1p with 1q additional copies or a biallelic deletion of 1p. Or a beta-2 microglobulin of at least 5.5 only when the creatinine is normal. This is a field-defining work that draws on analyses from across the world to put forward a dominant definition of high-risk disease and introduces a new era of biologically informed risk assessment in myeloma. Now, how does this change our clinical approach? FISH must be performed on CD138-enriched samples and should be performed for all patients. Next-generation sequencing should also be performed on all patients. Trials will hopefully now begin to include this novel definition of high-risk multiple myeloma. It does remain to be seen how data from novel therapeutic trials, if stratified according to this novel definition, will be interpreted. Will we find that therapies being evaluated at present have differential effects on myelomas with different genetic lesions? Other unanswered questions also exist. How do we go about integrating this into academic and then community clinical practice? How do we devise public health interventions for low-resource settings? To discuss this piece further, we welcome the esteemed Dr. Nikhil Munshi to the podcast. Dr. Munshi is a world-renowned leader in multiple myeloma and the corresponding author on this paper. As Professor of Medicine at Harvard Medical School, Director of the Multiple Myeloma Effector Cell Therapy Unit, and Director of Basic and Correlative Science at the Jerome Lipper Multiple Myeloma Center of the Dana-Farber Cancer Institute, he

Systemic Therapy for Tumor Control in Metastatic Well-Differentiated GEP-NETs Guideline

Dr. Jaydira Del Rivero and Dr. Kimberly Perez discuss the latest ASCO guideline featuring evidence-based recommendations on systemic therapy for well-differentiated grade 1 to grade 3 metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs). They discuss the recommendations, insights from the guideline expert panel, impact for clinicians and patients, and outstanding questions in the field. Read the full guideline update, "Systemic Therapy for Tumor Control in Metastatic Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors: ASCO Guideline" at www.asco.org/gastrointestinal-cancer-guidelines. TRANSCRIPT This guideline, clinical tools, and resources are available at http://www.asco.org/gastrointestinal-cancer-guidelines. Read the full text of the guideline and review authors' disclosures of potential conflicts of interest disclosures in the Journal of Clinical Oncology, https://ascopubs.org/doi/10.1200/JCO.23.01529 Brittany Harvey: Hello and welcome to the ASCO Guidelines Podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey and today I am interviewing Dr. Jaydira Del Rivero and Dr. Kimberly Perez, co-chairs on "Systemic Therapy for Tumor Control in Metastatic Well-differentiated Gastroenteropancreatic Neuroendocrine Tumors: ASCO Guideline." Thank you for being here, Dr. Del Rivero and Dr. Perez. Dr. Jaydira Del Rivero: Thank you. Dr. Kimberly Perez: Thank you, Brittany. Brittany Harvey: Then before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Del Rivero and Dr. Perez, who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology which is linked in the show notes. Now, to start us off on the content of this guideline, Dr. Del Rivero, can you provide an overview of both the scope and the purpose of this guideline? Dr. Jaydira Del Rivero: Thank you so much, Brittany for the introduction. I would also like to thank ASCO as well for giving us the opportunity, me and Dr. Perez, to discuss briefly the guidelines for gastroenteropancreatic neuroendocrine tumors. In terms of your question of providing an overview of the scope and purpose of this guideline, we wanted to make recommendations about the various systemic therapies and the management of advanced, unresectable, metastatic gastroenteropancreatic neuroendocrine tumors from grade 1 to grade 3. I'm fortunate to be the co-chair with Dr. Perez, but among the different experts and panelists on this guideline, it is important to establish a guide on how to manage patients with gastroenteropancreatic neuroendocrine tumors. And one of the reasons is because there really is not sequencing enough therapy, and there have been a lot of discussions even among the neuroendocrine tumor experts for at the same time provide information and guide to oncologists in the community to understand more about the management of these neuroendocrine tumors as well as provide in a more standardized manner about how a neuroendocrine tumor expert sees or manages a patient with neuroendocrine tumor. Brittany Harvey: Great. Thank you for providing that overview. So, you just mentioned that this guideline covers grade 1 to grade 3 gastroenteropancreatic neuroendocrine tumors. So, Dr. Perez, what are the general recommendations that the panel made for grade 1 to grade 3 gastroenteropancreatic neuroendocrine tumors? Dr. Kimberly Perez: Thank you, Brittany. I think the biggest take home for treatment for this group of tumors is based on the heterogeneity of the disease. We can classify this very broad group of tumors into grade 1 to 3 based on histologic features, and we use that to guide treatment. But we also take use the functionality of the tumors to direct treatment, and that can be assessed clinically as well as by functional imaging or nuclear medicine-based imaging. And that's really how our intention is in trying to provide recommendations for the treatment of these various tumor types. So, we, as a group in our discussions, it really came down to approaching the patient's situation, determining whether or not the patient had functional symptoms as a result of hormone excess, and then determining what their radiographic features were, specifically whether or not somatostatin receptor presence was noted and then the grade of the tumor and lastly, the bulk of disease and the rate of growth. And it's really those features that drive the different treatment options. Brittany Harvey: Excellent. Thank you for reviewing those general recommendations to identify those features that lead to specific treatment options. So, Dr. Del Rivero, what systemic therapy options are recommended for first, second, and later line therapies for grade 1 to grade 3 gastroenteropancreatic neuroendocrine tumors? Dr. Jaydira Del Rivero: As Dr. Perez mentioned earlier, neuroendocrine tumors are quite heterogeneous, and it's not a one-size-fits-all in terms of how we manage patients with neuroendocrine tumors. As Dr. Perez also mentioned, too, in terms of how we manage these neuroendocrine tumors, we need to consider the extension of the disease, whether it's low burden tumors versus high burden tumors. What is the pace of growth? Whether it's stable or rapidly progressive, and whether it's widely metastatic as well or if it's only localized in one area, liver-dominant disease. We also need to understand the primary site, and that's why these guidelines, we also divided it in terms of how we see it in terms of first and second line therapies between pancreas and small bowel neuroendocrine tumors. And as Dr. Perez said, the grade differentiation is also important. That's the reason why, when discussing and developing these guidelines, it was important to differentiate between grade 1, grade 2, as well as the grade 3. And also, as Dr. Perez mentioned, whether they are functional tumors, meaning they produce hormones or not and the symptoms related to that. And I just would also like to mention that we are currently working on the symptom management of neuroendocrine tumors, taking into consideration the hormone status of the tumors. That is something that we'll follow up in these guidelines as well. And as Dr. Perez mentioned whether they express somatostatin receptors or not. So based on that, the expert panelists as well in developing these guidelines, we divided them into grade 1 and grade 2 GI (or gastrointestinal) neuroendocrine tumors or pancreas neuroendocrine tumors. And that is based on the proliferation index as well. If the proliferation index of the Ki-67 is greater than 20%, we know that this is a grade 3 gastroenteropancreatic neuroendocrine tumor, which that, in itself is a different category in terms of management. Now, for gastrointestinal grade 1 and grade 2 neuroendocrine tumors, the first line of therapy, one of the things that we need to establish is whether the tumor expresses a somatostatin receptor or not, and that we confirm this via 68Ga-DOTA-peptides or 64Cu-DOTATATE scan. If they expressed the receptors, then I would initiate first line therapy or what is recommended in these guidelines is to start with a somatostatin agonist, either octreotide or lanreotide. One thing to mention here is that either octreotide or lanreotide is considered equivalent in terms of efficacy, we don't have any head-to-head comparison to determine which one may be better. We think it's equivalent, the two of them. And because of that, whichever is available is what we recommend. Now if there is evidence of disease progression after the use of a somatostatin agonist, we need to determine whether they still express somatostatin receptors. And as a second line therapy, we can consider patients as candidates for 177Lu-Dotatate or PRRT with 177Lu-Dotatate. Usually, our recommendations are, if the patient has a functional tumor, if it's producing hormones and symptoms related to hormone excess, we still continue the somatostatin agonist. But if the tumor is a non-functional tumor after disease progression on a somatostatin agonist, we don't necessarily need to continue with either lanreotide or long-acting octreotide. Now, sometimes, some of the discussions that were done as well when developing these guidelines is a concern about hematologic toxicity. And if there is any concern of hematologic toxicity, the patient may not be a candidate for 177Lu-Dotatate. In these situations, everolimus can be considered as a second or later line therapy in patients with G1 or G2 gastrointestinal neuroendocrine tumors. If the patient is somatostatin receptor negative, we can consider everolimus as well. As you can see, with GI neuroendocrine tumors, we really need to take into consideration what we discussed earlier today, and also discussed with Dr. Perez. Now, in terms of the grade 1 or grade 2 pancreatic neuroendocrine tumors, similar to what we discussed on the small bowel or gastrointestinal neuroendocrine tumors, we first need to determine whether the tumor is somatostatin receptor positive through scans such as 68Ga-DOTA-peptides or 64Cu-DOTATATE scan. Based on that, the first line is also considered, a somatostatin agonist, either octreotide or lanreotide. If there is disease progression on that, then we can consider other lines of therapy, such as Peptide Receptor Radionuclide Therapy or PRRT with 177Lu-Dotatate or chemotherapy with capecitabine and temozolomide, or everol

Lack of Gender Equity in Oncology Clinical Trial Advisory Board Membership

Shannon Westin, Pamela Kunz, and Rachna Shroff discuss the lack of gender equity on oncology industry advisory boards. TRANSCRIPT The guest on this podcast episode has no disclosures to declare. Dr. Shannon Westin: Hello, everyone, and welcome to another episode of the JCO After Hours podcast; our podcast where we get in-depth for articles in the Journal of Clinical Oncology. I am your fearless leader, and host, Shannon Westin, the Social Media Editor for the JCO, as well as a Professor of Gynecologic Oncology at MD Anderson Cancer Center. And I am so excited to introduce our two guests today. We are going to be discussing the article from the JCO, 'Where Are All the Women in Industry Advisory Boards?' And none of my guests have Conflict of Interest related to this work. So, first, let me introduce Dr. Rachna Shroff, she is from the University of Arizona, Tucson. She's not only the Interim Chief of the Division of Hematology/Oncology, she's the Associate Dean of Clinical and Translational Research, and Associate Professor of Medicine, the Chief of the Section of GI Medical Oncology, and the leader of the GI Clinical Research team. And somehow, we got her on this podcast. I don't know how she had the time. Welcome. Dr. Rachna Shroff: Thank you. So excited to be here. Dr. Shannon Westin: She is the first author on this paper, and she's also accompanied by the last author on this paper, Dr. Pamela Kunz, from the Yale School of Medicine, where she serves as Associate Professor of Internal Medicine, the Director of the Center for Gastrointestinal Cancers at Smilow Cancer Hospital, and Yale Cancer Center, the Chief of GI Medical Oncology, and the Vice Chief of Diversity, Equity, and Inclusion in Medical Oncology. Welcome. Dr. Pamela Kunz: Thank you. Really excited for this. Dr. Shannon Westin: I have to step up my game, man. This is an esteemed panel here. So, we're going to get right to it. I think this is such an important topic because you know, we've been seeing quite a bit of focus on gender equity in Oncology, I would say, really over the last five years, really, especially - yay. Where do you all see the biggest gaps? Like, what are we missing? What do we need to do? Dr. Rachna Shroff: Well, I'm happy to chime in, and I know that Dr. Kunz has her thoughts as well, but I agree with you. I think the first step to trying to address these gaps is just opening the conversation, and I think we have made tremendous strides in that regard. In terms of gaps, I mean, half of the reason that we even started thinking about this topic was really related to research, and opportunities for clinical trials, clinical research, drug development, and where women can try to increase their visibility and their opportunities. And the honest truth is, some of these things we see day-to-day when we see the number of women at the podium presenting pivotal trials, and the number of women that are lead authors on practice-changing papers. And that, I think, is really an area that needs to be talked about. And then, we need to work on the opportunities for solving these problems and coming up with solutions with everybody around the table, all of the key stakeholders engaged. Dr. Pamela Kunz: I completely agree. And you know, I think that because Dr. Shroff and I are both in the clinical trials space, you know, she and I have talked about this, and I think that industry-sponsored clinical trials are certainly one space, national clinical trial network trials are another space that we are also trying to move the needle, and I think that we really all have a collective responsibility in whatever we're doing to really try to ensure equity and representation, both of women, but also underrepresented minorities. And I think that the way I really like to personally think about this is, as Dr. Shroff said, if we can diversify the people who are leading the science, whether it's clinical trials, basic or translational, our science will in fact be better. We will ask more innovative, creative questions, and our patients will benefit from it. We will have more, I think, health equity because different people will be thinking about how to do the science. So, it's really critical and I think it's something that it is really exciting. I agree with you, Dr. Weston, that it's, "Yay," that we're having some recognition of this. And I think really step one is collecting data, benchmarking, figuring how we can do better. Dr. Shannon Westin: Yes. And I think that's a really nice segue to get into kind of what led you to explore this current area of focus around advisory board participation, and why that matters Dr. Pamela Kunz: Dr. Shroff, should I tell the story? Dr. Rachna Shroff: I was going to say, "Should we share our story?" Dr. Shannon Westin: Oh, I love a story. Yeah, definitely. Dr. Pamela Kunz: Oh, it's a good story. It's a good story. It involves Dr. Brian Alexander, who is one of our co-authors in this and is at Foundation. So, I was invited to participate in a Foundation Advisory Board, this was now, probably two years ago. And I have, as a practice, I now ask, "Who else is on the Advisory Board, and who is chairing the Advisory Board?" Because I've ended up, as I'm sure Dr. Shroff has as well, on advisory boards where I'm the only woman. And so, I've just as a policy, tried asking, and then I will also nudge if I notice that there's not great representation of women. And so, this was one of those times, and there were no other women advisors invited, and I objectively had a conflict, so I could not attend. And this was before I even knew Brian. I was like, "I'm going to email the CEO and the COO of Foundation." And I did, and immediately got a response. And in fact, really to Dr. Alexander's credit, he called me the next day and said, "We can't let this happen. How can we be part of the solution? We have some other fantastic industry partners intentionally as part of this author list, and I think we're really eager to try to partner in this. I think it takes an academic-industry partnership to try to move the needle here." So, I think it took some real vulnerability on Dr. Alexander's part to say, "We need to do better and to really do a deep dive." Dr. Shroff, any comments on that? And then you and I started texting, I think. Dr. Rachna Shroff: Yeah, No. So, similarly, I was asked to participate in I think, the same advisory board, but I also had a conflict, which is why Dr. Kunz did not see that I was one of the invitees. And so, that's how we started talking about it. And I agree. I think what was truly admirable was, of course, not just the immediate responsiveness, but the, "Let us be part of the solution." Like, "What can we do intentionally to try to shine a light on this?" And then, "What can we do to help find solutions?" But you know, I think it was interesting because once Dr. Kunz and I started talking about it, I also mentioned to her that I have had the privilege because I work in a very small research space of cholangiocarcinoma, that I have had the privilege of participating in an all-female advisory board. And it was again, a very purposeful creation and composition of an advisory board in partnership with industry and myself. I helped chair that advisory board, and it was night and day in terms of the way that the advisory board ran, the way in which there was engagement and participation. And so, we kind of started talking about, "Well, what if we started coming up with these types of solutions, and how could we flip the script and be able to see positive impact?" Dr. Shannon Westin: I'm an advisory board participant myself, in a predominantly female-driven cancer, and a female-dominant physician, and still, we have a long way to go in GYN oncology as well. I'm often the only woman at the table, and so, I'm so grateful to your leadership for kind of calling this out. I guess before we get too much into your paper, I want to be mindful for listeners that maybe don't participate in these advisory boards, can you give us a little bit of a rundown with what happens at these tables? Dr. Pamela Kunz: Dr. Shroff, I'm happy to let you start if you want to. Dr. Rachna Shroff: Okay. So, you know, advisory boards are typically composed of anywhere from five to 15, 20, sometimes participants. And usually, the composition is what are historically called KOLs. So, people who are thought of as thought leaders in a specific space, and advisory boards are typically organized by an industry partner, and that partner decides on the question, the question that they want the advisors to address. Oftentimes, it's related to a drug that they are developing, and it could be as early as, you know, "How do we design the initial clinical trials," to "How do we bring this to a phase III, and to the FDA, and to market?" So, it can be anywhere along the continuum of drug development. And the advisors are basically often given some, maybe a little bit of pre-reading and homework, but we basically come together. Pre-COVID, we came together in person, I think since COVID, it's been a little bit of a mix in terms of virtual opportunities as well as in-person opportunities. And it's anywhere from three-hour up to full-day, if not a day and a half of discussions in a room where the company, or the sponsor is asking very specific questions in terms of helping pick our brains and ask us to help develop their drug, and trial design, and help them focus their efforts in a very specific manner. Dr. Pamela Kunz: Yeah, maybe I'll add to that. So, the KOLs that Dr. Shroff mentioned are Key Opinion Leaders, and I think what's really interesting-- and I certainly learned more about this process in the course of writing the paper, but Key Opinion Leaders are really selected on the basis of metrics that are themselves biased. So, it's number of podium talks, number of publications, number of times you've maybe chaired a prior advisory boar

ASCO25 Preview: Key Research Accelerating Cancer Care

Dr. John Sweetenham and Dr. Erika Hamilton discuss top abstracts that will be presented at the 2025 ASCO Annual Meeting, including research on tech innovations that could shape the future of oncology. Transcript Dr. John Sweetenham: Hello, and welcome to the ASCO Daily News Podcast. I'm your host, Dr. John Sweetenham, and I'm delighted to be joined today by Dr. Erika Hamilton, a medical oncologist and director of breast cancer and gynecologic cancer research at the Sarah Cannon Research Institute in Nashville, Tennessee. Dr. Hamilton is also the chair of the 2025 ASCO Annual Meeting Scientific Program, and she's here to tell us about some of the key abstracts, hot topics, and novel approaches in cancer care that will be featured at this year's Annual Meeting. Our full disclosures are available in the transcript of this episode. Dr. Hamilton, it's great to have you on the podcast today, and thanks so much for being here. Dr. Erika Hamilton: Thanks, Dr. Sweetenham. I'm glad to be here. Dr. John Sweetenham: Dr. Hamilton, the Presidential Theme of the Annual Meeting this year is 'Driving Knowledge to Action: Building a Better Future,' and that's reflected in many of the sessions that will focus on action-oriented guidance to improve care for our patients. And as always, there'll be great presentations on practice-changing abstracts that will change treatment paradigms and transform care. Can you tell us about some of the hot topics this year and what you're particularly excited about? Dr. Erika Hamilton: You're right. Dr. Robin Zon's theme is 'Driving Knowledge to Action: Building a Better Future,' and you're going to see that theme really interlaced throughout the ASCO program this year. We had a record number of submissions. Over 5,000 abstracts will be published, and there'll be about 3,000 presentations, either in oral format or poster presentations. We have 200 dynamic sessions. Many of the discussants will be highlighting key takeaways and how we can translate action-oriented guidance to better treat our patients to build a better future. Our state-of-the-art science will include a Plenary Session. This will feature presentations as well as discussion of each of the presentations for clinical late-breaking abstracts. We have Clinical Science Symposia that I'm particularly excited about this year. These will feature key abstracts as well as discussions and a foundational talk around the subject. We're covering novel antibody-drug conjugate targets, turning "cold" tumors "hot" to include CAR T, as well as the future of cancer detection. There'll be rapid oral abstracts, case-based panels, and this will also feature interactive audience polling and case discussions. I also want to highlight the community connection opportunities. There will be 13 Communities of Practice that will be meeting on-site during ASCO, and there's also really a plethora of networking opportunities for trainees and early-career professionals, a Women's Networking Center, a patient advocate space, and I'm happy to report there will also be live music out on the terrace this year at ASCO. Dr. John Sweetenham: Well, that's going to be a really great addition. I have to say, I think this is always a special time of year because excitement starts to mount as the meeting gets closer and closer. And once the abstracts are out there, I certainly personally feel that the excitement builds. Talking of abstracts, let's dive into some of the key abstracts for this year's meeting. I'd like to start out by asking you about Abstract 505. This reports on 15-year outcomes for women with premenopausal hormone receptor-positive early breast cancer in the SOFT and TEXT trials. It assesses the benefits of adjuvant exemestane and ovarian function suppression or tamoxifen and ovarian function suppression. So, could you talk us through this and tell us what you think the key takeaways from this abstract are? Dr. Erika Hamilton: Absolutely. This is essentially the SOFT and TEXT trials. They are trials that we've been following for quite some time, evidenced by the 15-year outcome. And I think it really answers two very important questions for us regarding adjuvant endocrine therapy for patients that are facing hormone receptor-positive disease. The benefit of ovarian function suppression for one, and then second, the benefit of exemestane over tamoxifen, which is our SERM [selective estrogen receptor modulator]. So, in terms of the SOFT trial, when we talk about distance recurrence-free interval, which I really think is probably the most meaningful because secondary cancers, et cetera, are not really what we're getting at here. But in terms of distant recurrence-free interval, certainly with tamoxifen, using tamoxifen plus ovarian function suppression adds a little bit. But where we really get additional benefits are by moving to exemestane, an aromatase inhibitor with the ovarian function suppression. So, for example, in SOFT, for distant recurrence-free interval for patients that have received prior chemotherapy, the distance recurrence-free interval was 73.5% with tamoxifen, bumped up just a tiny bit to 73.8% with ovarian function suppression. But when we used both ovarian function suppression and switched to that aromatase inhibitor, we're now talking about 77.6%. It may seem like these are small numbers, but when we talk about an absolute benefit of 4%, these are the type of decisions that we decide whether to offer chemotherapy based on. So, really just optimizing endocrine therapy really can provide additional benefits for these patients. Just briefly, when we turn to TEXT, similarly, when we look at distance recurrence-free interval for our patients that are at highest risk and receive chemotherapy, tamoxifen and ovarian function suppression, 79%; 81% with exemestane and ovarian function suppression. And when we talk about our patients that did not receive chemotherapy, it increased from 91.6% up to 94.6%—very similar that 3% to 4% number. So, I think that this is just very important information when counseling our patients about the decisions that they're going to make for themselves in the adjuvant setting and how much we want to optimize endocrine therapy. Dr. John Sweetenham: Thanks so much for your insight into that. Dr. Erika Hamilton: Yeah, absolutely. So, let's turn to hematologic malignancies. Abstract 6506 reports exciting results on the new agent ziftomenib in relapsed/refractory NPM1-mutant acute myeloid leukemia. This is a phase 1b clinical activity study and safety results. This was the pivotal KOMET-001 study. And my question is, will this new agent fulfill an unmet need in this NPM1 space? Dr. John Sweetenham: Yeah, great question. And I think the answer is almost certainly 'yes'. So, just as some brief background, NPM1 mutation is known to be a driver of leukemogenesis in around 30% of patients with AML, and it's a poor prognostic factor. And typically, about 50% of these patients will relapse within a year of their first-line therapy, and only around 10% of them will get a subsequent complete remission with salvage therapy. Menin inhibitors, which disrupt the interaction between menin and KMT2A, are known to be active in NPM1-mutated as well as in KMT2A-rearranged AML. And ziftomenib is a selective oral menin inhibitor, which in this study was evaluated at a dose of 600 mg once a day, as you mentioned, a phase 1b/2 study, which is multicenter and presented by Dr. Eunice Wang from Roswell Park. It's a relatively large study of 112 patients who were treated with this standard dose with relatively short median follow-up at this time. The median age was 69 years, and median prior therapies were two, but with a range of one to seven. And I think very importantly, 60% of these patients had previously been treated with venetoclax, and 23% of them had had a prior transplant. Looking at the results overall for this study, the overall response rate was 35%, which is actually quite impressive. Specifically for those patients in the phase 2 part of the study, around 23% achieved a CR [complete remission] or CRh [complete remission with partial hematologic recovery]. What's very interesting in my mind is that the response rates were comparable in venetoclax-naive and venetoclax-exposed patients. And the drug was very well tolerated, with only 3% of patients having to discontinue because of treatment-related adverse events. And I think the authors appropriately conclude that, first of all, the phase 2 primary endpoint in the study was met, and that ziftomenib achieved deep and durable responses in relapsed and refractory NPM1-mutated AML, regardless of prior venetoclax, with good tolerance of the drug. And so, I think putting all of this together, undoubtedly, these data do support the potential use of this agent as monotherapy and as a new option for those patients who have relapsed or refractory NPM1-mutated acute myeloid leukemia. So, let's move on a little bit more now and change the subject and change gears completely and talk about circulating tumor DNA [ctDNA]. This has been a hot topic over a number of years now, and at this year's meeting, there are quite a few impactful studies on the use of ctDNA. We have time to focus on just one of these, and I wanted to get your thoughts on Abstract 4503. This is from the NIAGARA trial, which looks at ctDNA in patients with muscle-invasive bladder cancer who receive perioperative durvalumab. Could you tell us a little bit about this study? Dr. Erika Hamilton: So, this was the phase 3 NIAGARA trial, and this is literally looking for patients with muscle-invasive bladder cancer that are cisplatin-eligible, and the addition of durvalumab to neoadjuvant chemotherapy. So here, this is a planned exploratory analysis of ctDNA and the association with clinical outcomes from NIAGARA. So, this is really the type of study that helps u

JCO PO Article Insights: Prognostic Artificial Intelligence Nonmetastatic Prostate Cancer

In this JCO Precision Oncology Article Insights episode, Natalie DelRocco summarizes "Digital Pathology–Based Multimodal Artificial Intelligence Scores and Outcomes in a Randomized Phase III Trial in Men With Nonmetastatic Castration-Resistant Prostate Cancer" by Felix Y. Feng, et al published January 31, 2025. Come back for the next episode where JCO Precision Oncology Conversations host, Dr. Rafeh Naqash interviews the author of the JCO PO article discussed, Dr. Tim Showalter. TRANSCRIPT Natalie DelRocco: Hello and welcome to JCO Precision Oncology Article Insights. I'm your host Natalie Del Rocco. Today, we'll be discussing the article, "Digital Pathology-Based Multimodal Artificial Intelligence Scores and Outcomes in a Randomized Phase III Trial in Men With Nonmetastatic Castration-Resistant Prostate Cancer." We will also be discussing the accompanying editorial, "Leveraging Artificial Intelligence to Improve Risk Stratification in Nonmetastatic Castration-Resistant Prostate Cancer." So, we're going to start by summarizing the original report and then we'll jump into a few of the high-level interpretations that were supplied by the editorial. The original report by Feng et. al. describes the application of multimodal artificial intelligence to data collected on a nonmetastatic castration-resistant prostate cancer. We will call this disease moving forward NMCRPC, a Clinical Trial. So, we're looking at data from an NMCRPC clinical trial. The SPARTAN trial was a randomized phase three trial and this study compared metastasis-free survival as the primary endpoint for those treated with traditional androgen deprivation therapy or ADT to those treated with androgen deprivation therapy plus apalutamide. Other secondary endpoints included progression-free survival and overall survival, but the primary endpoint there was metastasis-free survival or MFS. This study found that the addition of apalutamide resulted in a significantly longer median metastasis-free survival compared to androgen deprivation therapy alone. And we should note that this is a double-blind placebo-controlled trial. In the overall study, 1,207 patients participated and over the course of this study histopathology slides were collected and they were digitized for future use. And that future use is what we are going to be discussing today. The authors do note that there are currently no good biomarkers for use in NMCRPC. The authors seem to be inspired by the ArteraAI prostate test, which was a recent application of multimodal artificial intelligence models. But in localized prostate cancer as opposed to NMCRPC, the authors constructed a multimodal artificial intelligence model or an MMAI model. They applied this to the SPARTAN trial with the intention of developing a risk score that could be used for risk stratification in NMCRPC. And we should note here that multimodal artificial intelligence or MMAI is a broad class of artificial intelligence models, and they can analyze different types of data at one time, hence the term multimodal. So in this example, the author's primary data source of interest were those digitized histopathology images because histopathology tells you a lot about NMCRPC. The authors though also wanted their model to consider traditional clinical factors that are known to be prognostic such as Gleason score, tumor stage, PSA level, and age. So those two different types of data, those histopathology images and that traditional clinical data are the two different types of data that make this model multimodal. So we should note here importantly, after dropping missing data, 420 patients contribute to this model, the MMAI model. The authors generate a risk score from this MMAI model and they categorize that risk score into low, intermediate, and high risk groups using clinical knowledge. The authors found in their results that an increase in this MMAI risk score was associated with an increased hazard of metastasis-free survival event with a hazard ratio from a Cox proportional hazards model of 1.72. To summarize how the authors arrived here, they derived a risk score from this MMAI model which incorporates both imaging and regular data. They plugged this risk score into a Cox proportional hazards mode,l modeling metastasis-free survival and they found that an increase in that MMAI based risk score is associated with increased hazard of metastasis-free event with a hazard ratio of 1.72, which is quite large. Additionally, the risk score seemed to be associated with PFS2 and OS, which were two of the secondary endpoints from the SPARTAN clinical trial, though the effect sizes were more modest. Those are the highlights from the original report, the methods and the results. The accompanying editorial notes that both histopathology and Gleason score specifically are very critical to understanding prostate cancer, and Gleason score alone is not sufficient to summarize the complexity of the disease, although it is a well validated prognostic factor for prostate cancer. So this makes MMAI an excellent tool in the setting described by the authors. We have an existing prognostic factor that doesn't describe the entire picture of the disease by itself and so we can use those digitized histopathology slides to help bolster our understanding and provide the model more information. MMAI allows you to do this because it can take in different types of data. So that was the main conclusion of the editorial. They also summarize a number of recent validations of MMAI models in prostate cancer research, noting that it will be an important tool for risk stratification and has already been shown to outperform classical techniques. The editorial though does highlight a number of weaknesses of this paper, limitations and I think the most important one to highlight, and we touched on this earlier, is that 420 patients from the SPARTAN clinical trial contributed to the development of this MMAI score. That is a small proportion of the roughly 1200 patients that did participate in the SPARTAN clinical trial. So we have a small subgroup analysis that can be limiting and this model will need to be validated in a broader population in the future.

Transcriptomic Profiling of Non-Localized Prostate Cancer

JCO PO author Dr. Amar U. Kishan, Professor, Executive Vice Chair, and Chief of Genitourinary Oncology Service in the Department of Radiation Oncology at the University of California, Los Angeles, shares insights into his JCO PO article, "Transcriptomic Profiling of Primary Prostate Cancers and Nonlocalized Disease on Prostate-Specific Membrane Antigen Positron Emission Tomography/Computed Tomography: A Multicenter Retrospective Study." Host Dr. Rafeh Naqash and Dr. Kishan discuss the relationship between Decipher genomic classifier scores and prostate-specific membrane antigen (PSMA) PET/CT-based metastatic spread. TRANSCRIPT Dr. Rafeh Naqash: Hello and welcome to JCO Precision Oncology Conversations, where we bring you engaging conversations with authors of clinically relevant and highly significant JCO articles. I'm your host, Dr. Rafeh Naqash, Assistant Professor at the OU Health Stephenson Cancer Center at the University of Oklahoma. Today we are joined by Dr. Amar Kishan, Executive Vice Chair of the Department of Radiation Oncology at the David Geffen School of Medicine at UCLA and UCLA Jonsson Comprehensive Cancer Center, and also the corresponding and senior author of the JCO Precision Oncology article entitled, "Transcriptomic Profiling of Primary Prostate Cancers and Non Localized Disease on Prostate-Specific Membrane Antigen (PSMA) Positron Emission Tomography/Computed Tomography: A Multicenter Retrospective Study." Dr. Kishan, welcome to our podcast and thank you for joining us today. Dr. Amar Kishan: Thank you so much for that kind introduction and the invitation to be here today. Dr. Rafeh Naqash: Well, it seems to me that there's a theme that people in the GU space, investigators in the GU space, are very interested in trying to understand risk predictors for prostate cancer. We had somebody, I believe from Huntsman Cancer Center a few months back on a previous podcast, where they were trying to do risk prediction modeling as well. Could you tell us why that's something that the GU community is very interested in? What's the background? Is it because there's no risk prediction approaches currently? And would this somehow influence management in the near future? Dr. Amar Kishan: Yeah, that's a great question. So, I think this goes back to the point that we're in the era of precision medicine now, and many cancers have these molecular stratification scores and all that. Prostate cancer has lagged a little bit behind in that regard, despite the fact that it's such a common cancer that affects so many people across the country and across the world. So, we do have risk stratification schemes for prostate cancer. These are based off clinical and pathologic variables, like the level of PSA, the size of the tumor on digital rectal examination, now, we're incorporating MRI imaging as well, and then what the cancer looks like under the microscope, the Gleason score. And now there have been revisions to the Gleason score, but it's really kind of the architecture, what the biopsy looks like. And this was kind of developed many, many years ago by Donald Gleason, a pathologist at the VA. What we're not necessarily taking into account routinely is kind of the biology of the cancer per se. You know, what are the molecular drivers? How could that influence ultimate outcome? And that's very important because we have these risk groups, low risk, very low risk, favorable intermediate risk, unfavorable intermediate risk, high risk, very high risk. But within each of those groups, based on the clinical kind of pathological characteristics, there's a huge heterogeneity in outpatients too, and our treatments are effective, but they can be morbid. Putting someone on hormone therapy for an extended period of time has a lot of side effects. Dose escalating radiotherapy or doing surgery and then radiation afterwards, these are big things that have a big impact on the patient, and I think we really need better risk stratification tools to understand who needs intensification and who we can de-escalate treatment for. Dr. Rafeh Naqash: I think those are absolutely valid points, perhaps not just for prostate cancer, more so for all cancers that we currently treat, especially in the current day and age, where we have a tendency to add more and more therapies, combination therapies for patients, and as you mentioned, risk stratification to help identify high risk versus low risk, where you can de intensify treatment, is of high value from a patient standpoint as well as from a financial toxicity standpoint. So then, going to this next part of the approach that you used, and from what I understand in this paper, you had the radiological aspect, which is the PSMA PET, which we'll talk about. Then you had the genomic aspect, where you did some genomic risk-based stratification. Then you had the transcriptomic score based on the Decipher score. So, could you go into some of the details, first, for the PSMA PET, when is it used? What is the utilization? What is it based on, the science behind the PSMA PET? And then we can talk about some of the other genomic transcriptomic predictors that you use in this study. Dr. Amar Kishan: Sure. Absolutely. So, a PSMA PET is an advanced molecular imaging tool. PSMA stands for prostate specific membrane antigen. It's a membrane protein that is expressed on the surface of prostate cancer cells. It is expressed elsewhere in the body as well. The utilization of this for imaging has been a revolution in the staging of prostate cancer, both upfront and in the recurrent setting. We basically had fairly recent approval for PSMA PET being used more routinely in upfront staging and recurrent staging in 2022. Essentially, what this is it gives us an ability to detect whether prostate cancer has spread at a time of diagnosis or try to localize the recurrence. Now, no imaging test is perfect, of course, and a PET has a resolution of about 3 mm. There are questions about the sensitivity of the PET. You get it on a patient with high-risk disease, the PET is negative; you do surgery, there are positive lymph nodes. That can happen, but it's far superior to the tools that we have had before. For instance, beforehand, all we would have is a contrast enhanced CT, bone scan, and MRI. And the sensitivity of those is far below that of a PSMA PET. And that has actually been shown in a randomized trial called the ProPSMA trial out of Australia, where they compared conventional upfront imaging versus PSMA upfront imaging with a crossover design, and there was better detection of disease with the PSMA PET. So that's been a revolution in how we stage prostate cancer. But I'm sure many of your listeners and others are aware of the concerns. When you get a new test and you're detecting disease that's extra prostatic, for instance, are you seeing truly significant new disease that we do need to change our management for, or are we just seeing stuff that wasn't there before that actually wouldn't impact anything? And what I mean by that is, let's say you're seeing things that would never have made a difference to the patient, but now you're saying they have metastatic disease. You're changing their entire treatment paradigm, all kinds of things like that. There's implications to this that hasn't been fully fleshed out. But very recently, like we're talking in July of 2024, essentially, there was a Lancet Oncology paper that looked at the long-term prognosis of patients who had extra prostatic disease on PSMA PET, judged by something called a PROMISE score, kind of gives a quantification on the volume of disease, the brightness of disease, and they correlated that with long term outcomes. And that was really the first time that we have long term follow up data that this extra prostatic disease on PSMA PET actually is prognostically important. So, we're getting there. I mean, now that it's approved and, in some sense, the cat is out of the bag, patients are coming in asking for a PSMA PET, etc. I'm sure everyone has experienced that, but I think we now do have good evidence that it actually is prognostically important as well. Dr. Rafeh Naqash: Thank you for that explanation. And again, to put this into context for things that I've seen and that might also help the listeners in other tumors, so, for example, melanoma surveillance tends to be or while on treatment, patients tend to have more PET scans than what you see, maybe in individuals with lung cancer, where you get a baseline PET and then you have follow up CT scan based imaging is that something that you guys have shifted from in the prostate cancer space with the approval for PSMA PET, where follow up imaging, whether patient is on treatment or surveillance imaging, is PSMA PET based? Dr. Amar Kishan: Yeah, that's a good question. I think there's actually less robust data to support it as a means of treatment response. But in terms of evaluating a recurrence, then, yes, that has become kind of a standard tool. It's very complicated because all of the metrics that we have for, say, a treatment failing are based on conventionally detected metastases or something that shows up on a CT or bone scan. So, again, that question arises if someone is on systemic therapy and then you see something on a PSMA PET, are you going to abandon the therapy that you're on? It technically would be earlier than you would otherwise have done that, or what are you going to do? So, that hasn't been fully fleshed out, but it is used in that circumstance. So, I'd say less for treatment monitoring and more for evaluation of suspected recurrence. Dr. Rafeh Naqash: Understood. And I'm guessing, as a futuristic approach, somebody out there may perhaps do a trial using PSMA PET based imaging to decide whether treatment change needs to be made or does not need to be made. Dr. Amar Kishan: Yeah. It is being incorporated into trials as we speak, I think. Dr. Rafeh Naqas
