Simon J. Crabb, PhD, MBBS, on Urothelial Carcinoma: Switch Maintenance Therapy With Rucaparib Following Chemotherapy
2022 ASCO Genitourinary Cancers Symposium
Simon J. Crabb, PhD, MBBS, of the Southampton Experimental Cancer Medicine Centre, discusses data from the ATLANTIS trial, in which the authors hypothesized that switch maintenance therapy with the PARP inhibitor rucaparib, in patients who have derived clinical benefit from first-line chemotherapy, may improve outcomes for those with metastatic urothelial carcinoma that harbored a composite biomarker for DNA repair deficiency (Abstract 436).

Massimo Di Maio, MD, of the University of Turin, discusses the Meet-URO12 study, which showed that maintenance niraparib plus best supportive care (BSC) did not prolong progression-free survival, compared with BSC alone, among patients with urothelial cancer that did not progress after first-line platinum-based chemotherapy.

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.

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.

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).
