Heinz-Josef Lenz, MD, of USC Norris Comprehensive Cancer Center, discusses how treating microsatellite instability–high/DNA mismatch repair–deficient metastatic colorectal cancer with nivolumab once every 2 weeks plus low-dose ipilimumab every 6 weeks may represent a new option for patients (Abstract 11).
Scott Kopetz, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses phase III findings from the BEACON CRC trial, which had demonstrated that the triplet regimen of encorafenib, cetuximab, and binimetinib significantly improved overall survival in patients with a BRAF V600E mutation. The new analysis showed that the regimen also led to substantial improvement in patient-reported quality of life compared with current standard of care (Abstract 8).
Van K. Morris, MD, of The University of Texas MD Anderson Cancer Center, discusses the COBRA study, which is examining circulating tumor DNA and its ability to predict whether patients with resected stage IIA colon cancer may benefit from adjuvant chemotherapy (Abstract TPS261).
Franck Pagès, MD, PhD, of the Hôpital Européen Georges Pompidou, discusses study findings from the prospective IDEA France cohort study of patients with stage III colon cancer treated with mFOLFOX6. The study showed that patients with an intermediate or high Immunoscore seemed to benefit from 6 months of mFOLFOX6 treatment compared with 3 months (Abstract 10).
Thibaud Kössler, MD, PhD, of Geneva University Hospital, discusses the first trial to study the efficacy and safety of anti–PD-1 immunotherapy plus short-course radiotherapy in localized microsatellite-stable rectal cancer. The study explores whether a gene signature can predict sensitivity to immunotherapy (Abstract TPS272).
Zev A. Wainberg, MD, of the UCLA Medical Center, discusses the first subset analysis of how a combined positive score in gastric and gastroesophageal junction cancers related to the efficacy of pembrolizumab in PD-L1–positive disease (Abstract 427).
