Abstract

Objective: Statins have been demonstrated to improve outcomes in patients receiving immune checkpoint blockade (ICB). This study aimed to investigate whether the timing of statin administration influences the outcomes of patients receiving ICB.

Methods: We conducted a retrospective cohort study utilizing electronic health records from two tertiary referral centers in Taiwan. We compared the overall survival (OS) and progression-free survival (PFS) of patients who received statins before and after ICB initiation.

Results: We included 734 patients who received ICB. Among them, 606 were non-statin users, 76 started statins after ICB initiation, and 52 started statins before ICB initiation. Post-ICB statin users demonstrated significantly prolonged OS (median 37.6 versus 10.3 versus 11.3 months, p = 0.009) and PFS (median 10.5 versus 6.3 versus 5.6 months, p = 0.024) compared to pre-ICB statin and non-statin users. Statin use after ICB initiation had a reduced risk of all-cause mortality (HR, 0.65 [95% CI: 0.45-0.94], p = 0.022) and progressive disease (HR, 0.71 [95% CI: 0.53-0.95], p = 0.021) by approximately 30-35%, compared to non-statin users. However, statin use prior to ICB initiation did not affect the risk of all-cause mortality or progressive disease. Similar results were observed after controlling for potential cofounders such as age, sex, cancer stage, and cancer type.

Conclusions: These findings suggest that initiating statin therapy after the initiation of ICB, regardless of indication, is associated with improved patient prognosis.
