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).
Karim Fizazi, PhD, MD, of Gustave Roussy and University of Paris-Saclay, discusses results from a first-in-human phase I/II trial, which showed that administering ODM-208—an oral, nonsteroidal inhibitor of the enzyme CYP11A1—to men with metastatic castration-resistant prostate cancer who were pretreated with abiraterone/enzalutamide and taxanes was effective in blocking the production of steroid hormones. It also showed antitumor activity, especially in men with AR mutation–positive cancers.
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.

As reported in the Journal of Clinical Oncology by Stockler et al, enzalutamide was associated with worsening in several quality-of-life domains—but not in overall health and quality of life—vs standard of care in the phase III ENZAMET trial evaluating the efficacy of the agent for patients with...
In October 2021, the National Comprehensive Cancer Network (NCCN) prostate caycer panel modified its guidelines (NCCN Clinical Practice Guidelines in Oncology [NCCN Guidelines®]) for low-risk prostate cancer to remove the word “preferred option” for active surveillance, giving equal weight to...
In a Finnish study reported in JAMA Oncology, Vettenranta et al found that statin use did not appear to markedly affect the benefits of prostate-specific antigen (PSA) screening for prostate cancer. As stated by the investigators, “PSA screening for prostate cancer has resulted in a slight...

In a study published by Abashidze et al in JAMA Network Open, the investigators found that Black men were at least 23.6% less likely than White men to undergo magnetic resonance imaging (MRI) following an elevated prostate-specific antigen (PSA) test result. They also found that Hispanic and Asian...
The immune checkpoint protein B7-H3 may be a potential new target in treatment-resistant prostate cancers, according to two studies presented recently at the European Society for Medical Oncology (ESMO) Congress 2021. “Virtually every prostate cancer cell expresses some degree of B7-H3, which...
Amar U. Kishan, MD, of the University of California, Los Angeles, discusses findings from a meta-analysis of clinical trials in patients with localized prostate cancer. The phase III results suggest that the use of androgen-deprivation therapy (ADT) or prolonged adjuvant ADT with radiotherapy may benefit patients with localized prostate cancer. Further biomarkers are needed to better personalize treatment intensification (Abstract 8).
Mark K. Buyyounouski, MD, MS, of Stanford University, discusses phase III results from the NRG Oncology GU003 trial, which showed that, post-prostatectomy, using fewer—but higher—doses of radiation does not appear to increase long-term side effects or reduce quality of life when compared with conventional radiation treatment (Abstract 3).
Benjamin Movsas, MD, of the Henry Ford Cancer Center, discusses results from the NRG Oncology/RTOG 0815 study, which explored dose-escalated radiotherapy alone or in combination with short-term hormonal therapy for patients with intermediate-risk prostate cancer. In addition to clinical outcomes, Dr. Movsas discusses patient-reported results in the study that may help patients make informed decisions when choosing between these treatment options (Abstract 4).
Cleveland Clinic researchers have shown that diet-associated molecules in the gut may be associated with aggressive prostate cancer, suggesting dietary interventions may help reduce risk. These findings were published by Reichard et al in Cancer Epidemiology, Biomarkers & Prevention. While...
As reported in The Lancet Oncology by Bancroft et al, the first round of prostate cancer screening in the IMPACT study of men with pathogenic variants in mismatch repair genes showed an increased risk of prostate cancer in carriers of MSH2 and MSH6 variants compared with noncarrier controls. As...
