Priya Rastogi, MD, of the University of Pittsburgh, discusses results from the NRG Oncology/NSABP B-42 trial, which evaluated the utility of the 70-gene MammaPrint assay in predicting the benefit of extended letrozole therapy in patients who had completed 5 years of adjuvant endocrine therapy (Abstract 502).
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).
Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses phase III results from KEYNOTE-564, which evaluated the safety and efficacy of pembrolizumab in the adjuvant treatment of patients with renal cell carcinoma who have undergone nephrectomy for intermediate-high or high-risk disease or no evidence of disease (Abstract LBA5).
Sumanta K. Pal, MD, of City of Hope, discusses results from a phase II study that sought to determine whether adding berzosertib, a selective ATR inhibitor, to the standard upfront chemotherapy regimen of cisplatin with gemcitabine may improve outcomes in patients with metastatic urothelial carcinoma (Abstract 4507).
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).
