The Association of Statin Use With Survival Outcomes in Patients With Metastatic Castration-Resistant Prostate Cancer (mCRPC) Treated With Androgen Receptor Targeted Therapies (ART).

Statins may provide a compounded effect on ART by decreasing cholesterol levels thus decreasing de novo androgen synthesis and tumor cell viability. We investigated the clinical efficacy of concurrent statin use on outcomes of patients with mCRPC taking ART.

A single-institution retrospective analysis of patients with mCRPC receiving ART from 2010 to 2021 was performed. Our primary outcome was PSA progression free survival (PFS), and our secondary outcomes were overall survival (OS). Patient characteristics were collected in addition to ART treatment course, statin treatment, and survival outcomes. Cox proportional hazards regression model was used to estimate hazard ratios (HR) for OS and PSA PFS and multivariable logistic regression to determine risk factors.

153 patients with mCRPC treated with ART were included. A total of 67 patients (43.8%) received concurrent statins. Median PSA PFS was 20.4 months for patients that received statins versus 15.3 months for patients who did not receive statins. Median OS was 45.1 months for patients who received concurrent statins versus 29.7 months for patients who did not. On univariate and multivariate survival analyses, there was no statistically significant difference between groups for PSA PFS (HR 0.7; CI 0.44-1.1; P = .123) and OS (HR 0.67; CI 0.42-1.06; P = .089).

Our analysis suggests that statins do not significantly improve clinical outcomes in patients with mCRPC. Ultimately, current understanding remains limited, and prospective studies are needed, but here we provide a cost-effective, timely, and selective preliminary analysis.
