[MUSIC PLAYING] BRITTANY HARVEY: 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 Brittany Harvey. And today I'm interviewing Dr. Beverly Moy from Massachusetts General Hospital in Boston, Massachusetts, co-chair and lead author on chemotherapy and targeted therapy for patients with HER2 negative metastatic breast cancer that is either endocrine pre-treated or hormone receptor negative ASCO guideline update. Thank you for being here, Dr. Moy. BEVERLY MOY: Thanks for having me, Brittany. BRITTANY HARVEY: First, 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 full conflict of interest information for this guideline panel is available online with the publication of the guideline in the Journal of Clinical Oncology. Dr. Moy, do you have any relevant disclosures that are directly related to this guideline topic? BEVERLY MOY: I do not have any relevant disclosures related to this guideline topic. BRITTANY HARVEY: Great. Thanks so much. Then let's get into what this update covers. So first, what prompted the update of this ASCO guideline and what does the scope of this guideline update? BEVERLY MOY: So this guideline update was developed to address both chemotherapy and targeted therapy for women with advanced HER2 negative breast cancer that is either endocrine pre-treated or hormone receptor negative. So it really focuses on chemo and targeted therapy. The original ASCO clinical treatment guideline was published in 2014 and really focused on chemotherapy, since that was generally the standard of care at that time. Since 2014, however, there have been several important new therapies that have become available based on robust evidence from numerous clinical trials. These include, but are not limited to, BOLERO-6 and PEARL trials for hormone receptor positive HER2 negative metastatic breast cancer, the ASCENT and EMBRACE trials for triple negative metastatic breast cancer, and the EMBRACA trial for metastatic breast cancer associated with germline BRCA1 or 2 mutations. So it really was important to update the guideline in a fairly urgent matter. BRITTANY HARVEY: Great. Well, then this guideline addresses four overarching clinical questions. For each of these, I'd like to review the key recommendations for our listeners. So starting with question one, is there an optimal sequence of chemotherapy and/or targeted therapy for patients with triple negative metastatic breast cancer either with or without BRCA1 or BRCA2 germline mutations? BEVERLY MOY: So clinical question one really focused on patients with metastatic triple negative breast cancer. So for patients with metastatic triple negative disease, the first key question is,
