Ann S. LaCasce, MD, of Dana-Farber Cancer Institute, discusses results from the CALGB 50801 Alliance study, which showed that a PET scan–adapted approach may reduce the need for radiation treatment and may improve progression-free outcomes in patients with stage I/II bulky classic Hodgkin lymphoma (Abstract 7507).
Evan J. Lipson, MD, of Johns Hopkins University, discusses primary phase III results from the RELATIVITY-047 study, which showed that relatlimab plus nivolumab as a fixed-dose combination may improve progression-free survival compared with nivolumab monotherapy in patients with advanced melanoma. This is the first study to demonstrate a benefit from dual inhibition of the LAG-3 and PD-1 pathways.
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).
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).
Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, discusses two abstracts from a session she co-chaired: the phase II DEEPER trial, which explored the use of FOLFOXIRI plus cetuximab vs FOLFOXIRI plus bevacizumab as first-line treatment in metastatic colorectal cancer with RAS wild-type tumors; and the phase II FIRE-4.5 study, which investigated FOLFOXIRI plus either bevacizumab or cetuximab as first-line treatment of BRAF V600E–mutant advanced disease (Abstracts 3501 and 3502).
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).
