Abstract

Purpose This clinical practice guideline addresses abiraterone or docetaxel with androgen-deprivation therapy (ADT) for metastatic prostate cancer that has not been treated (or has been minimally treated) with testosterone-lowering agents. Methods Standard therapy for newly diagnosed metastatic prostate cancer has been ADT alone. Three studies have compared ADT alone with ADT and docetaxel, and two studies have compared ADT alone with ADT and abiraterone. Results Three prospective randomized studies (GETUG-AFU 15, STAMPEDE, and CHAARTED) examined overall survival (OS) with adding docetaxel to ADT. STAMPEDE and CHAARTED favored docetaxel (hazard ratio [HR], 0.78; 95% CI, 0.66 to 0.93; n = 2,962 and HR, 0.73; 95% CI, 0.59 to 0.89; n = 790, respectively). GETUG-AFU 15 was negative. LATITUDE and STAMPEDE examined the impact on OS of adding abiraterone (with prednisone or prednisolone) to ADT. LATITUDE and STAMPEDE favored abiraterone (HR, 0.62; 95% CI, 0.51 to 0.76; n = 1,199 and HR, 0.63; 95% CI, 0.52 to 0.76; n = 1,917, respectively). Recommendations ADT plus docetaxel or abiraterone in newly diagnosed metastatic non-castrate prostate cancer offers a survival benefit as compared with ADT alone. The strongest evidence of benefit with docetaxel is in men with de novo high-volume (CHAARTED criteria) metastatic disease. Similar survival benefits are seen using abiraterone acetate in high-risk patients (LATITUDE criteria) and in the metastatic population in STAMPEDE. ADT plus abiraterone and ADT plus docetaxel have not been compared, and it is not known if some men benefit more from one regimen as opposed to the other. Fitness for chemotherapy, patient comorbidities, toxicity profiles, quality of life, drug availability, and cost should be considered in this decision.
