Tracy L. Rose, MD, on Bladder Cancer: Gemcitabine, Cisplatin, and Pembrolizumab as Neoadjuvant Therapy
2021 Genitourinary Cancers Symposium
Tracy L. Rose, MD, of the University of North Carolina at Chapel Hill, discusses phase II results of gemcitabine and split-dose cisplatin plus pembrolizumab as neoadjuvant therapy prior to radical cystectomy for patients with muscle-invasive bladder cancer. The trial showed this combination treatment is generally safe and may improve pathologic downstaging, but further study is warranted (Abstract 396).
Thomas Powles, MD, PhD, of Cancer Research UK Barts Centre, discusses phase III results from the EV-301 trial, which showed that enfortumab vedotin is the first therapy to demonstrate a significant survival advantage over standard chemotherapy in patients with previously treated locally advanced or metastatic urothelial carcinoma (Abstract 393).
Christopher Sweeney, MBBS, of Dana-Farber Cancer Institute, discusses phase III findings from the IPATential150 trial, which showed the effectiveness of ipatasertib plus abiraterone as first-line treatment in patients with metastatic castration-resistant prostate cancer vs placebo plus abiraterone. Analyses of biomarkers linked to the PI3K/AKT pathway, a subtype with a poor prognosis, further support this therapeutic option (Abstract 13).
A spirited discussion ensued when we asked Christopher Sweeney, MBBS, of Dana-Farber Cancer Institute, and Thomas Powles, MD, PhD, of Cancer Research UK Barts Centre, to compare notes on how they treat bladder, prostate, and kidney cancers.
Daniel M. Geynisman, MD, of Fox Chase Cancer Center, discusses phase II results from the RETAIN BLADDER study, which sequenced bladder tumor samples while treating patients with neoadjuvant methotrexate, vinblastine, doxorubicin, and cisplatin chemotherapy. The goal was to increase metastasis-free survival and also preserve the bladder and quality of life (Abstract 397).
Neeraj Agarwal, MD, of Huntsman Cancer Institute at the University of Utah, discusses final results of the phase III TITAN study, which showed apalutamide plus androgen-deprivation therapy improved overall survival, reducing the risk of death up to 48%. This combination treatment also delayed castration resistance and maintained health-related quality of life for patients with metastatic castration-sensitive prostate cancer (Abstract 11).
