The only paper we found that reported an inverse correlation between vitamin D and leukemia incidence was a nested case-control study from the Health Professionals Follow-up Study, which found a suggestive inverse association was observed for leukemias (RR = 0.44, 95% CI = 0.20 to 1.00) based on 82 cases1.
That study used a vitamin D index based on oral vitamin D intake and recreational exposure to solar UVB for 1000 men, then applied to all 50,000 men in the study. Significant inverse correlations were found for colorectal, esophageal, gastric, oral/pharyngeal, and pancreatic cancer, most of which have been reported as vitamin D-sensitive in other studies2 3.
