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).
Peter Reichardt, MD, PhD, of Helios Klinikum Berlin-Buch, discusses the 10-year survival analysis of 3 years vs 1 year of adjuvant imatinib for patients with high-risk gastrointestinal stromal tumor. The study found that about 50% of deaths can be avoided with longer imatinib treatment (Abstract 11503).
Christopher Sweeney, MBBS, of Dana-Farber Cancer Institute, talks with Thomas Powles, MD, PhD, of Queen Mary University of London, about the first study to demonstrate a survival advantage with avelumab for metastatic urothelial cancer. In the trial, avelumab improved median overall survival by 21.4 months compared with 14.3 months with best supportive care (Abstract LBA1).
Lakshmi Nayak, MD, of Dana-Farber Cancer Institute, reviews two key abstracts on newly diagnosed primary central nervous system lymphoma and treatment with whole-brain radiotherapy, methotrexate, temozolomide, rituximab, procarbazine, vincristine, and cytarabine (Abstracts 2500 and 2501).
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).
Daniel P. Petrylak, MD, of the Yale Cancer Center, discusses early data on ARV-110, an androgen receptor proteolysis–targeting chimera degrader, demonstrating antitumor activity in metastatic castration-resistant prostate cancer after treatment with enzalutamide and abiraterone (Abstract 3500).
