Josh Neman, PhD, of the Keck School of Medicine, University of Southern California, discusses the distribution of brain metastasis to preferential brain regions that vary according to cancer subtype, how neurotransmitters respond, and the ways in which the central nervous system acclimates (Abstract SY32).
Nickolas Papadopoulos, PhD, of the Sidney Kimmel Comprehensive Cancer Center, discusses early detection as the key to reducing cancer mortality and the lack of tests for many malignancies. Liquid biopsies have the potential to screen for various tumor types, albeit with varying levels of sensitivity. Dr. Papadopoulos discusses his research on such blood tests, following patients prospectively to find the best combination of genetic and epigenetic biomarkers to increase sensitivity (Abstract PL02).
Timothy A. Yap, MBBS, PhD, of The University of Texas MD Anderson Cancer Center, discusses results from the PETRA study, a first-in-class, first-in-human trial of the next-generation PARP1-selective inhibitor AZD5305 in patients with BRCA1/2, PALB2, or RAD51C/D mutations in advanced or metastatic ovarian cancer, HER2-negative breast cancer, pancreatic, or prostate cancer. Target engagement was demonstrated across all dose levels, and antitumor activity was observed in selected tumor and molecular subtypes.
Gautam Mehta, MD, of the U.S. Food and Drug Administration, discusses how accelerated approval of potentially life-saving cancer therapies has been applied in precision oncology. Although “fast-tracking” drugs presents opportunities and challenges, one possible measure of the program’s success is the fact that, to date, no solid tumor accelerated-approval indications have been withdrawn (Abstract DC06).
Silvia C. Formenti, MD, of Weill Cornell Medicine, discusses research on the best way to integrate radiotherapy with immune modifiers, which might require changes in standard radiation oncology practices. Variables such as the type of treatment fields, the inclusion of draining nodal stations, the degree of exposure of circulating immune cells, the type of dose fractionation, and the timing of radiotherapy during immune checkpoint blockade all can affect the success of immunoradiotherapy combinations (Abstract SY43).
Vivek Subbiah, MD, of The University of Texas MD Anderson Cancer Center, talks about innovative design of clinical studies that may help demonstrate clinical benefit in precision medicine and advance treatment to deliver the right intervention to the right patient at the right time (Abstract DC06).
