In a study published by Salem et al in Circulation, researchers examined how several testosterone-blocking drugs commonly used in the treatment of prostate cancer affect the heart's QT interval. The longer a QT interval—typically measured by an electrocardiogram—the more at risk a ...
In patients with prostate cancer with surgical positive margins or extracapsular extension of their disease, the risk of disease recurrence postprostatectomy is higher than in cases where the cancer cells are confined within the prostate. The Finnish FinnProstataX study investigated...
On July 30, the U.S. Food and Drug Administration (FDA) approved darolutamide (Nubeqa) for the treatment of nonmetastatic castration-resistant prostate cancer. Approval was based on the ARAMIS study, a multicenter, double-blind, placebo-controlled clinical trial of 1,509 patients with...

WHEN ASKED which treatment to start with—docetaxel or enzalutamide, Dr. Sweeney said, “Patients fit for chemotherapy with high-volume disease can receive chemotherapy [docetaxel] and come back to these newer hormonal treatments or start with anyone of the hormonal options. Choosing among the newer...
