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).
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).
Eyal Meiri, MD, of the Cancer Treatment Centers of America at Southeastern Regional Medical Center, discusses his findings on heavily pretreated patients with colorectal cancer with high tumor mutational burden. Monotherapy with pembrolizumab showed antitumor activity, which merits further study to confirm efficacy (Abstract 133).
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).
Peter R. Galle, MD, of the University Medical Center, Mainz, discusses patient-reported outcomes from this phase III study, which showed the combination of atezolizumab plus bevacizumab vs sorafenib is well tolerated and may represent a new standard of care in the first-line setting for unresectable liver cancer (Abstract 476).
