Kim Nguyen Chi, MD, on Prostate Cancer: New Findings on Niraparib, Abiraterone, and Prednisone
2022 ASCO Genitourinary Cancers Symposium
Kim Nguyen Chi, MD, of the University of British Columbia, BC Cancer-Vancouver Center, discusses first phase III results from the MAGNITUDE study, which explored the use of the PARP inhibitor niraparib with abiraterone acetate and prednisone as first-line therapy in patients with metastatic castration-resistant prostate cancer with and without homologous recombination repair gene alterations (Abstract 12).

Karen E. Knudsen, PhD, MBA, Chief Executive Officer of the American Cancer Society, discusses ways to address the inequities in genitourinary screening, treatment, and outcomes. Her suggestions focus on increasing awareness of screening, identifying risk factors, the dramatic rise in incidence among Hispanic individuals, and the basis for increased mortality in Black men.

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).

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).

Hielke-Martijn de Vries, MD, of the Netherlands Cancer Institute, discusses phase II findings on the use of atezolizumab with or without radiotherapy for patients with advanced squamous cell carcinoma of the penis. The study was designed to address the poor prognosis for this disease by exploring whether a protracted schedule of radiotherapy for locoregional disease, in combination with immunotherapy, could improve outcomes (Abstract 3).

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).
