The TRUMPET registry: Assessing clinical outcomes and quality of life in patients with castration-resistant prostate cancer and their caregivers.

241 Background: Patient care in castration-resistant prostate cancer (CRPC) is complex, with varying treatment patterns due to differences in therapies, patient characteristics, and physician practices. The impact of such patterns on clinical outcomes and quality of life (QoL) represent a contemporary medical issue. This study aims to improve the understanding of clinical outcomes and QoL of patients with CRPC and their caregivers. Methods: TRUMPET is a prospective, observational, multi-center study of patients with CRPC in the United States. Approximately 2000 patients and their caregivers (if eligible) will be enrolled over 24 months from IRB-approved urology and oncology sites. Eligible patients with CRPC include those with life expectancy of ≥ 6 months initiating the first active course of anti-cancer treatment for M0 or M1. A 48-month observation period will follow the last patient enrolled. Primary objectives are to describe longitudinal patterns of care, disease assessment methods, treatment decisi...
