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).
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).
Ingrid A. Mayer, MD, of Vanderbilt University Medical Center, discusses phase III results from a trial that showed patients with triple-negative breast cancer who had residual invasive disease after neoadjuvant chemotherapy had lower-than-expected invasive disease–free survival, regardless of study treatment with platinum-based chemotherapy or capecitabine (Abstract 605).
Byoung Chul Cho, MD, PhD, of the Yonsei Cancer Center, discusses study results that showed treatment with the EGFR-MET bispecific antibody amivantamab plus the EGFR inhibitor lazertinib yielded responses in 36% of chemotherapy-naive patients with non–small cell lung cancer whose disease progressed on osimertinib. Genetic biomarkers may be able to identify patients most likely to benefit from the combination regimen (Abstract 9006).
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).
