Health-related quality of life (HRQoL) patient-reported outcomes (PROs) and survival (OS) in metastatic castration-resistant prostate cancer (mCRPC) patients (pts).

53 Background: HRQoL is a relevant endpoint in trials in advanced prostate cancer. An association between HRQoL and OS has been reported. The Functional Assessment of Cancer Therapy-Prostate (FACT-P) is a validated HRQoL PRO in mCRPC.

FACT-P scores, sub-scores (physical (PWB), emotional (EWB), functional (FWB),...
