Umang Swami, MD, on Prostate Cancer: Differences in Genomic, Transcriptomic, and Immune Landscape Based on Site of Metastasis
2024 ASCO GU Cancers Symposium
Umang Swami, MD, of Huntsman Cancer Institute at the University of Utah, describes the molecular and immunologic mechanisms of metastatic tropism in advanced prostate cancer, data that may facilitate future drug development. In patients with metastatic disease, specific sites are associated with differential overall survival, but the biological reasons have not been fully explored (Abstract 21).
Maha H.A. Hussain, MD, of the Robert H. Lurie Comprehensive Cancer Center, Northwestern University, discusses phase II findings from the BRCAAway trial. This study showed that in patients with metastatic castration-resistant prostate cancer with BRCA1/2 or ATM alterations, abiraterone and prednisone plus olaparib was well tolerated and resulted in a longer progression-free survival than either agent alone or sequentially.
Thomas Powles, MD, of Barts Cancer Institute, Cancer Research UK Experimental Cancer Medicine Centre, and Queen Mary University of London, discusses outcomes reported by patients with previously treated renal cell carcinoma (RCC), taking part in the phase III LITESPARK-005 study. Belzutifan was associated with a prolonged time to deterioration, fewer disease-specific symptoms, and better quality of life compared with everolimus (Abstract 361).
Andrew Johns, MD, of The University of Texas MD Anderson Cancer Center, discusses efficacy, safety, and tolerability data on tivozanib. The agent yielded a modest clinical benefit in a minority of patients with advanced clear cell renal cell carcinoma who received prior immune checkpoint–based therapies, cabozantinib, and lenvatinib with or without everolimus (Abstract 419).
Andrea B. Apolo, MD, of the National Cancer Institute, National Institutes of Health, discusses the results of the AMBASSADOR Alliance A031501 study, which showed adjuvant pembrolizumab improved disease-free survival vs observation for patients with high-risk muscle-invasive urothelial carcinoma after radical surgery. According to Dr. Apolo, the findings support adjuvant pembrolizumab as a new treatment option for this population (Abstract LBA531).
Michiel S. Van Der Heijden, MD, PhD, of the Netherlands Cancer Institute, discusses phase III results from the global EV-302 study, showing that enfortumab vedotin-ejfv plus pembrolizumab improves outcomes in patients with previously untreated locally advanced metastatic urothelial carcinoma compared with chemotherapy. Overall survival benefit was observed across select prespecified subgroups. According to Dr. Van Der Heijden, this immunotherapy combination is a potential new standard of care for first-line locally advanced metastatic urothelial carcinoma (Abstract LBA530).
