Christopher Sweeney, MBBS, on Prostate Cancer: Analyzing Biomarkers, Ipatasertib Plus Abiraterone
2021 Genitourinary Cancers Symposium
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).
Sumanta K. Pal, MD, of City of Hope, discusses phase II results from the SWOG 1500 study, which showed that compared with crizotinib and savolitinib, cabozantinib was the only agent that prolonged progression-free survival vs sunitinib in patients with metastatic papillary renal cell carcinoma (Abstract 270).
Elizabeth R. Plimack, MD, of Fox Chase Cancer Center, discusses key abstracts discussed at this year’s meeting on renal cell carcinoma and offers her views on the latest trends and findings (Abstracts 269, 308, 270, 313).
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).
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).
Elizabeth R. Plimack, MD, of Fox Chase Cancer Center, discusses phase III results from the KEYNOTE-426 study—specifically, an exploratory subgroup analysis of patients with advanced renal cell carcinoma who were randomly assigned to receive pembrolizumab plus axitinib and completed 2 years of treatment (Abstract 327).
