Thierry André, MD, of Hôpital Saint-Antoine, discusses final overall survival data for the phase III KEYNOTE-177 study, which confirmed pembrolizumab as a new standard of care for first-line treatment of patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract 3500).
Peter H. O’Donnell, MD, of The University of Chicago, discusses response and survival results from the phase II KEYNOTE-052 study, which showed that after up to 5 years of follow-up, pembrolizumab continued to elicit clinically meaningful, durable antitumor activity in cisplatin-ineligible patients with advanced urothelial cancer (Abstract 4508).
Terry P. Mamounas, MD, MPH, of the University of Florida Health Cancer Center, discusses results from the NRG Oncology/NSABP B-42 study, which examined the Breast Cancer Index and its ability to predict whether extended treatment with letrozole benefits patients with hormone receptor–positive breast cancer (Abstract 501).
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses first phase III results from a prospective high-risk cohort of patients with luminal breast cancer, which showed a good prognosis in some women with more than four positive lymph nodes and low recurrence scores. The study also showed that a lower postendocrine Ki67 index and limited tumor burden may be promising criteria for chemotherapy de-escalation strategies, even in patients with high recurrence scores (Abstract 504).
Jingxuan Zhao, MPH, of the American Cancer Society, discusses study findings that showed worse long-term survival among low-income patients with cancer who live in states that have not expanded Medicaid eligibility (Abstract 6512).
Taiga Nishihori, MD, of the H. Lee Moffitt Cancer Center and Research Institute, discusses the outcome of a trial that explored maintenance therapy with ixazomib after allogeneic hematopoietic cell transplantation in patients with high-risk multiple myeloma. Toxicities unrelated to the maintenance treatment forced the trial to close prematurely (Abstract 7003).
