Dr. Sepideh Gholami and Dr. Aaron Scott join us to discuss the latest evidence-based guideline from ASCO on the management of locally advanced rectal cancer. They review the recommendation highlights on topics including assessment, total neoadjuvant therapy, timing of chemotherapy, nonoperative management, and immunotherapy. Additionally, we discuss the importance of this guideline for both clinicians and patients, and the outstanding research questions in the management of locally advanced rectal cancer.

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'm interviewing Dr. Aaron Scott from the University of Arizona Cancer Center and Dr. Sepideh Gholami from Northwell Health, co-chairs on, “Management of Locally Advanced Rectal Cancer: ASCO Guideline.” Thank you for being here, Dr. Scott and Dr. Gholami.

Dr. Sepideh Gholami: Thank you for having us.

Brittany Harvey: Then, before we discuss this guideline, I'd 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. Scott and Dr. Gholami, who have joined us here today, are available online with a publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.

And with the advent of the total neoadjuvant approach, we really have seen tremendous changes. So the purpose really of these guidelines was to consolidate the various approaches that we've had in several clinical trials and to provide the oncology community a general management recommendation guideline to really optimize the outcomes for these patients. And I would further notice that with the specifics to like which patients are included for these, so we define patients with locally advanced rectal cancer as any of those patients with T3 or T4 tumors and/or lymph node positive disease.

Brittany Harvey: Great. I appreciate you providing that background and context of this guideline.

So then, next, I'd like to review the key recommendations of this guideline. So, Dr. Scott, starting with the first section of the guideline, what are the recommendations for assessment of locally advanced rectal cancer?

Dr. Aaron Scott: Yeah, thank you. So really, we were charged with trying to answer, I think, several very important questions as it comes to the treatment of locally
