Neil E. Fleshner, MD, MPH, on High-Risk Prostate Cancer: New Data on Abiraterone and Cabazitaxel
2022 ASCO Genitourinary Cancers Symposium
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.

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).

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).

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).

Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses a 30-month follow-up of results from the KEYNOTE-564 trial, which further support the use of adjuvant pembrolizumab when treating patients with renal cell carcinoma at intermediate-high or high risk of recurrence, or with an M1 NED (no evidence of disease) status after nephrectomy. The data show a disease-free survival benefit vs placebo (Abstract 290).

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.
