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).

Neil E. Fleshner, MD, MPH, of the Princess Margaret Cancer Centre, discusses phase II results from the ACDC-RP trial, which indicate a significant tumor response to neoadjuvant abiraterone acetate plus prednisone and leuprolide, with or without cabazitaxel, in patients with high-risk prostate cancer. Those who exhibited either a complete response or minimal residual disease experienced higher rates of progression-free survival. According to Dr. Fleshner, genomic efforts are underway to determine predictors of response.

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.

Petros Grivas, MD, PhD, of the University of Washington and Fred Hutchinson Cancer Research Center, discusses results from Cohort 3 of the TROPHY-U-01 study, which assessed sacituzumab govitecan-hziy in combination with pembrolizumab in patients with metastatic urothelial cancer who experienced disease progression after platinum-based regimens (Abstract 434).

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).

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.
