As reported in The New England Journal of Medicine by Karim Fizazi, MD, PhD, of Gustave Roussy Institute, Paris-Saclay University, and colleagues, the phase III TRITON3 trial has shown significantly improved progression-free survival with rucaparib vs physician-selected single-agent therapy in the...
Formal discussant of the FORMULA-509 trial, Tyler Seibert, MD, PhD, of the University of California San Diego, commented: “The important take-away of these results is who benefited from the intensification arm.

Alex K. Bryant, MD, of the University of Michigan, examined Veterans Administration (VA) facilities in which lower prostate-specific antigen (PSA) screening rates were associated with a subsequent increased incidence of metastatic prostate cancer, particularly among men aged 70 and older. From 2008 to 2019, PSA screening rates have declined in the national VA system, data that may be used to inform shared decision-making about the potential benefits of screening for those who wish to reduce their risk of advanced prostate cancer. (Abstract 298).
Rahul Aggarwal, MD, of the University of California, San Francisco, discusses recent data from the PRESTO study, which showed that apalutamide plus androgen-deprivation therapy (ADT) for 12 months significantly prolonged PSA progression-free survival compared with ADT alone in patients with biochemically recurrent prostate cancer. These results provide support for the intensification of ADT in this setting. (Abstract LBA63).

Scott T. Tagawa, MD, of Weill Cornell Medicine, NewYork-Presbyterian Hospital, discusses study results showing that, the anti-PSMA (prostate-specific membrane antigen) monoclonal antibody J591 with ketoconazole and hydrocortisone, when radiolabeled with lutetium-177, leads to improved 18-month metastasis-free survival vs radiolabeling with indium-111 in patients with nonmetastatic (M0) castration-resistant prostate cancer. This supports the development of anti-PSMA radioimmunotherapy, although the optimal radionuclide and targeting agent are unknown. (Abstract LBA21).
Alan H. Bryce, MD, of the Mayo Clinic, discusses the final results of the primary endpoint of rPFS and interim results on overall survival among patients with chemotherapy-naive metastatic castration-resistant prostate cancer. The data showed that rucaparib improved radiographic progression-free survival compared with either docetaxel or abiraterone and enzalutamide in disease with BRCA1/2 alterations. (Abstract 18).
Daniel P. Petrylak, MD, of the Yale Cancer Center, discusses phase III findings from the KEYNOTE-921 study, which was designed to assess the combination of pembrolizumab and docetaxel in the treatment of patients with metastatic castration-resistant prostate cancer. They had not received chemotherapy, but their disease progressed on the next-generation hormonal agent, or they could not tolerate the agent. (Abstract 19).
Paul L. Nguyen, MD, of Dana-Farber Cancer Institute and Harvard Medical School, discusses results from the FORMULA-509 study, which compared postoperative salvage radiotherapy and 6 months of GnRH agonist with or without abiraterone acetate/prednisone (AAP) and apalutamide, after radical prostatectomy. The study suggested that adding AAP and apalutamide to salvage radiotherapy, plus 6 months of androgen-deprivation therapy, may improve outcomes, particularly in the subgroup of patients with a prostate-specific antigen level higher than 0.5 ng/mL. (Abstract 303).
Investigators have estimated the environmental impacts of prostate magnetic resonance imaging (MRI) scans and prostate biopsies, according to a new study published by Michael S. Leapman, MD, MHS, and colleagues in European Urology. The findings suggest that more carefully selecting patients for...
Neeraj Agarwal, MD, of the Huntsman Cancer Institute, University of Utah, discusses phase III results from the TALAPRO-2 study, which suggested an improvement in radiographic progression-free survival with the combination of talazoparib and enzalutamide over standard-of-care enzalutamide alone as first-line treatment in patients with metastatic castration-resistant prostate cancer. The improvement was seen regardless of homologous recombination repair gene mutations. The combination regimen delayed the time to chemotherapy and worsening in global health status and quality of life. (Abstract LBA17).
