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.

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
