Incidence of Second Primary Malignancies in Castration-Resistant Prostate Cancer: An Observational Retrospective Cohort Study in the US

Trial purpose

This study is conducted to estimate population-based incidence rates of second primary malignancies among patients with CRPC similar to those treated with Xofigo. These rates will provide context for second primary malignancy incidence rates from the REASSURE study.
Furthermore this study aims to provide further information about the documentation of bone metastases in Medicare data and the extent of use of only oral androgen deprivation drugs among patients with Medicare Part D coverage, as well as to estimate overall survival of the study population.
