Alberto F. Sobrero, MD, of the Ospedale San Martino, discusses final results of the IDEA study, which supported the use of 3 months of adjuvant CAPOX, vs 6 months, for most patients with stage III colon cancer. The shorter treatment duration reduced toxicity, inconvenience, and cost (Abstract 4004).
Jeffrey A. Meyerhardt, MD, MPH, of Dana-Farber Cancer Institute, discusses results from the CALGB/SWOG 80702 trial of celecoxib plus standard adjuvant therapy with fluorouracil, leucovorin, and oxaliplatin (FOLFOX). Adding celecoxib to standard chemotherapy did not significantly improve disease-free or overall survival (Abstract 4003).
Nancy U. Lin, MD, of Dana-Farber Cancer Institute, discusses the HER2CLIMB study of patients with previously treated HER2-positive metastatic breast cancer that had metastasized to the brain. Adding tucatinib to trastuzumab and capecitabine doubled the intracranial response rate and reduced the risk of death by nearly half, compared with trastuzumab plus capecitabine (Abstract 1005).
Parameswaran Hari, MD, of the Medical College of Wisconsin, discusses data from four trials and their clinical implications for the treatment of patients with multiple myeloma: the KarMMa and EVOLVE studies on CAR T cell therapies; SWOG-1211 on bortezomib, lenalidomide, and dexamthasone with/without elotuzumab for newly diagnosed, high-risk disease; and the GMMGCONCEPT trial on isatuximab, carfilzomib, lenalidomide, and dexamethasone in front-line treatment (Abstracts 8503, 8504, 8507, 8508).
David R. Wise, MD, PhD, of New York University Perlmutter Cancer Center, summarizes three important studies in prostate cancer: circulating tumor cell count as a prognostic marker of PSA response and progression in metastatic castration-sensitive disease; new phenotypic subtypes; and how circulating tumor DNA dynamics associate with treatment response and radiologic progression-free survival (Abstracts 5506, 5507, and 5508).
Egbert F. Smit, MD, PhD, of the Netherlands Cancer Institute, discusses interim results from the DESTINY-Lung01 trial of fam-trastuzumab deruxtecan in patients with HER2-mutated metastatic non–small cell lung cancer. The data show clinical activity with high overall response rates and durable responses (Abstract 9504).
