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).

Tanya B. Dorff, MD, of City of Hope National Medical Center, discusses the first-in-human phase I findings showing that prostate stem cell antigen (PSCA) CAR T-cell therapy is feasible in patients with metastatic castration-resistant prostate cancer, with preliminary antitumor activity exhibited.

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).

Alicia K. Morgans, MD, MPH, of Dana-Farber Cancer Institute, discusses findings from the largest digital survey conducted in patients with prostate cancer, allowing identification of unmet needs in the patient journey. Preliminary data suggest that lower rates of screening may correlate with higher rates of symptoms at diagnosis and potentially later-stage diagnosis.

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).

Wesley Yip, MD, of Memorial Sloan Kettering Cancer Center, discusses phase II results on neoadjuvant gemcitabine and cisplatin for high-grade upper tract urothelial carcinoma, which was well tolerated and demonstrated a favorable pathologic response rate. Dr. Yip notes that this treatment, given prior to nephroureterectomy, did not significantly delay surgery or increase perioperative complication rates.
