  • Serum 25-OH vitamin D levels and risk of developing prostate cancer in older men CANCER CAUSES & CONTROL Barnett, C. M., Nielson, C. M., Shannon, J., Chan, J. M., Shikany, J. M., Bauer, D. C., Hoffman, A. R., Barrett-Connor, E., Orwoll, E., Beer, T. M. 2010; 21 (8): 1297-1303


    Multiple studies have shown clear evidence of vitamin D's anti-tumor effects on prostate cancer cells in laboratory experiments, but the evidence has not been consistent in humans. We sought to examine the association between vitamin D and prostate cancer risk in a cohort of older men.We conducted a prospective case-cohort study nested within the multicenter Osteoporotic Fractures in Men (MrOS) study. Baseline serum 25-OH vitamin D was measured in a randomly selected sub-cohort of 1,433 men > or = 65 years old without a history of prostate cancer and from all participants with an incident diagnosis of prostate cancer (n = 297). Cox proportional hazards models were used to evaluate the associations between quartiles of total 25-OH vitamin D and incident prostate cancer, as well as Gleason score.In comparison with the lowest quartile of 25-OH vitamin D, the hazard ratio for the highest quartile of 25-OH vitamin D was 1.22 (CI 0.50-1.72, p = 0.25), no trend across quartiles (p = 0.94) or association with Gleason score was observed. Adjustment for covariates did not alter the results.In this prospective cohort of older men, we found no association between serum 25-OH vitamin D levels and subsequent risk of prostate cancer.
