Popis: | e16080 Background: Corticosteroids (CS) have been integral in metastatic castration-resistant prostate cancer (mCRPC) treatment and can be used alongside life-extending therapies (LETs), despite potential toxicity effects. LET and CS timing and adherence were examined in CRPC patients in the Veterans Health Administration (VHA) dataset with conditions sensitive to CS use. Methods: Diagnosed prostate cancer patients with evidence of medical/surgical castration, at least two following prostate-specific antigen (PSA) increases (third PSA value date was the index), and ≥1 claim for cabazitaxel, docetaxel, or abiraterone acetate 06/2007-05/2012 were examined. Adherence was the total overlapping days of CS and LET prescriptions divided by total LET prescription days (≥0.8). Comorbid conditions were measured for 6 months pre-index date. Descriptive analysis, Cox proportional hazards, and logistic regression models summarized therapeutic/clinical features of CRPC or the CS-adherent patient subset. Results: Common CS-sensitive conditions among 15,585 mCRPC patients included hypertension (58.94%) and hyperlipidemia (42.56%). Fewer glaucoma (hazard ratio [HR]: 0.67), ischemic heart disease (HR: 0.78), and peripheral vascular disease (HR: 0.78) patients were prescribed LETs (all p |
