Serum tumor markers can be a blessing and a curse. After definitive local therapy for prostate cancer, prostate-specific antigen (PSA) is quite sensitive and specific, and can detect micrometastatic disease well before any radiographic or symptomatic evidence of disease. When biochemical recurrence (BCR) occurs, early detection can guide curative-intent salvage therapies such as salvage radiation.

In the ARASENS trial (NCT02799602), darolutamide in combination with androgen-deprivation therapy (ADT) and docetaxel significantly reduced the risk of death by 32.5% (HR, 0.68; 95% CI, 0.57-0.80; P < .0001) compared with placebo plus ADT with docetaxel in patients with metastatic hormone-sensitive prostate cancer (mHSPC). We present efficacy and safety of darolutamide versus placebo in Black patients from ARASENS.
