Fred Saad, MD, on Prostate Cancer: Results From the PROpel Trial on Olaparib and Abiraterone
2022 ASCO Genitourinary Cancers Symposium
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).
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).
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.
Axel Bex, MD, PhD, of The Netherlands Cancer Institute, discusses an efficacy, safety, and biomarker analysis of neoadjuvant avelumab and axitinib in patients with localized renal cell carcinoma who are at high risk of relapse after nephrectomy (Abstract 289).
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.
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.
