Van K. Morris, MD, on Stage II Colon Cancer: Circulating Tumor DNA as a Predictive Biomarker in Adjuvant Chemotherapy
2020 Gastrointestinal Cancers Symposium
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).
Danielle S. Bitterman, MD, of the Harvard University Radiation Oncology Program and Massachusetts General Hospital, discusses an analysis of genomic and clinical data from 97 patients with pancreatic ductal adenocarcinoma with circulating tumor DNA. Mutations were most frequently detected in patients with locally advanced and metastatic disease (Abstract 753).
Eileen M. O’Reilly, MD, of Memorial Sloan Kettering Cancer Center, discusses phase II trial findings showing that cisplatin and gemcitabine, with or without veliparib, exceeded a prespecified response rate for patients with pancreatic adenocarcinoma and a germline BRCA/PALB2 mutation (Abstract 639).
Thomas Yau, MBBS, of the University of Hong Kong, discusses this triplet combination, which yielded better responses than doublet combination therapy in patients with advanced liver cancer, but with more severe adverse events and more treatment discontinuations (Abstract 478).
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).
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).
