Chronic use of NSAIDs and/or statins does not impact longitudinal PSA or PSA velocity in men at high risk for prostate cancer - Abstract

Background: Prostate specific antigen (PSA) and PSA velocity (PSAV, rate of PSA change over time) are biomarkers for diagnosis and prognosis of prostate cancer (PCa).

Men who are at high risk for PCa also have associated co-morbidities for which they are taking NSAIDs and statins for long periods; therefore it is important to understand the effect of these medications on markers used to assess PCa risk.

Methods: Using a population of 699 men, multiple linear regressions were used to investigate the associations between PSA and concomitant medications; and mixed effects models were used to investigate these associations with PSAV.

Results: After adjusting for selenium use, age, race, body mass index, and pack-years of smoking; aspirin, other NSAIDs, or statins did not demonstrate statistically significant associations with PSA (p = 0.79, 0.68, and 0.79 respectively) or PSAV (p = 0.23, 0.43, and 0.84 respectively). Results were not altered upon stratifying the sample between men who developed PCa during the course of the study and those who did not.

Conclusions: Results from this study indicate that chronic use of aspirin, other NSAIDs, or statins did not impact PSA levels or PSAV in men at high risk for PCa. Larger prospective studies designed to investigate these relationships are needed to confirm this result.

Impact: Long-term use of NSAIDs or statins in men at high risk for PCa may not interfere with the diagnosis or prognosis of this disease, and supports appropriate use of these medications with regard to PCa risk.
