Molecular Biomarkers in Localized Prostate Cancer Guideline ASCO Guidelines

    • Medicine

An interview with Dr. Scott Eggener of University of Chicago Medicine on "Molecular Biomarkers in Localized Prostate Cancer: ASCO Guideline." This guideline provides recommendations for available tissue-based prostate cancer biomarkers geared toward patient selection for active surveillance, identification of clinically significant disease, choice of postprostatectomy adjuvant versus salvage radiotherapy, and to address emerging questions such as the relative value of tissue biomarkers compared with MRI.

Hello and welcome to the ASCO Guidelines Podcast Series brought to you by the ASCO Podcast Network, a collection of nine programs covering a range of educational and scientific content and offering enriching insight into the world of cancer care. You can find all the shows including this one at podcast.asco.org. My name is Shannon McKernin. And today I'm interviewing Dr. Scott Eggener from the University of Chicago Medicine, lead author on molecular biomarkers in localized prostate cancer ASCO Guideline. Thank you for being here today, Dr. Eggener.

Thanks for having me, Shannon, and covering the guideline.

So first, can you give us a general overview of what this guideline covers?

Yeah, this guideline has been two years in the making and is an overview of the available molecular biomarkers to help clinicians and patients make smart decisions for men with localized prostate cancer. And that's in the newly diagnosed setting, as well as for certain patients that have undergone surgery and are considering adjuvant radiation therapy.

And so what are the key recommendations for this guideline?

So there was a lot of data that the team looked through with the help of the ASCO home office, and a Herculean amount of work went into it. There's a lot of commercially available tests out there. Most of them are quite expensive. And we are trying to make sense of the available literature and provide a guide to clinicians on what these tests are, which patients they might be relevant for, and how to interpret them.

The key takeaways that the data that's been published for most of these biomarkers are purely prognostic. And there is good science and good data supporting them. But they have not been embedded in a rigorous fashion or within trials or validated to have the highest level of evidence. However, they can be used in certain situations to add additional info for the patient and clinician to try to make smart decisions based on prognostic information.

Another key recommendation is that there are select patients that these can be helpful for. And we dive into a lot of the details on who these patients may be. Number one is a patient newly diagnosed with prostate cancer who is trying to determine whether to do treatment of the prostate cancer or embark on active surveillance. And some of those decisions are relatively easy and straightforward.

But when the clinician and the patient are looking for all pieces of information to influence one way or the other, genomic or molecular biomarkers can be useful at that critical fork in the road. However, we made it very clear mul
