based prostate cancer screening trial.

Data was used from a Finnish population-based study of prostate cancer screening that randomized men to PSA screening or routine care. All men aged 55-67 years at baseline and residing in the Tampere or Helsinki districts of Finland were included. Information on statin purchases was obtained from a national prescription registry. Eligible men from the population registry of Finland were identified and men already diagnosed with prostate cancer were excluded.

The men were randomly assigned to 1 of 2 groups: the first group received 3 invitations for PSA screening at 4-year intervals.  The second group received “routine care,” some of which also may have elected to undergo PSA screening.  The study population included 78,606 men with a median age of 59 years with statin-purchase data available.  The statin users had a lower incidence of low-risk (Gleason score 6, grade group 1 and clinically localized tumors); where, the rates of high-grade tumors (Gleason score of 8 to 10, grade group 4 or 5) were similar in the two groups.  PSA screening was associated with a lower incidence of metastatic tumors regardless of statin use.  These results suggest that statin use does not compromise the benefits of PSA screening.
