Sumanta K. Pal, MD, on Advances in Genitourinary Cancer Treatment: Expert Perspective
2022 ASCO Genitourinary Cancers Symposium
Sumanta K. Pal, MD, of City of Hope National Medical Center, discusses some key research developments in kidney cancer, including data on nivolumab and ipilimumab with or without CBM588 in metastatic renal cell carcinoma; intestinal microbiome associated with the development of grade 3 or 4 adverse events in patients with metastatic disease who have been treated with nivolumab plus ipilimumab and probiotic support; the link between TERT promoter mutations and clinical outcome with immune checkpoint inhibitor therapy for advanced urothelial cancer; mutations in the androgen receptor gene in patients with prostate cancer receiving novel androgen deprivation treatments; and findings on waning antibody titers in patients who have received COVID-19 vaccinations (Roundup of Abstracts 371, 561, 374, Posters 38 and 48).

Fred Saad, MD, of the University of Montreal Health Centre, discusses phase III findings demonstrating for the first time the clinical benefits of olaparib plus abiraterone in patients with metastatic castration-resistant prostate cancer, irrespective of their homologous recombination repair mutation status. This regimen led to significantly longer radiographic progression-free survival than placebo plus abiraterone (Abstract 11).

Matthew R. Zibelman, MD, of Fox Chase Cancer Center, discusses phase I/II results from a study of treatment-naive patients with advanced renal cell carcinoma who received a combination of the immunotherapy (IO) nivolumab and the tyrosine kinase inhibitor (TKI) axitinib. The findings suggest that the efficacy of this regimen is comparable to that of currently available IO/TKI combinations for this population and has a similar safety profile (Abstract 291).

Jonathan E. Rosenberg, MD, of Memorial Sloan Kettering Cancer Center, discusses phase II findings from the BAYOU trial, which studied durvalumab in combination with olaparib for first-line treatment of platinum-ineligible patients with unresectable, stage IV urothelial carcinoma. Because secondary analyses indicated a potential progression-free survival benefit with this combination, there may be a role for PARP inhibitors in the treatment of advanced disease with homologous recombination repair mutation (Abstract 437).

Massimo Di Maio, MD, of the University of Turin, discusses the Meet-URO12 study, which showed that maintenance niraparib plus best supportive care (BSC) did not prolong progression-free survival, compared with BSC alone, among patients with urothelial cancer that did not progress after first-line platinum-based chemotherapy.

Alfredo Berruti, MD, of Italy’s University of Brescia, discusses the first study to give adjuvant mitotane to patients with adrenocortical carcinoma, a rare disease with a high risk of relapse after radical surgery. Although theoretically this treatment may be clinically worthwhile, the findings suggest that the need for adjuvant mitotane should always be discussed on a case-by-case basis by the multidisciplinary team, and more study is warranted (Abstract 1).
