Epidemiological studies suggest that vitamin and mineral intake is associated with cancer incidence. A prevention strategy based on diet or dietary supplementation could have enormous benefit, both directly, by preventing disease, and indirectly by alleviating fear in millions of people worldwide who have been exposed to asbestos. We have previously shown that dietary supplementation with the antioxidants vitamins A, E, and selenium does not affect overall survival nor the time to progression of asbestos-induced mesothelioma in MexTAg mice. Here we have extended our analysis to vitamin D. We compared survival of asbestos-exposed MexTAg mice provided with diets that were deficient or supplemented with 4500 IU/kg vitamin D (cholecalciferol). Survival of supplemented mice was significantly shorter than mice given a standard AIN93 diet containing 1000 IU/kg cholecalciferol (median survival was 29 and 32.5 weeks respectively). However, mice deficient in vitamin D had the same rate of mesothelioma development as control mice. Neither the latency time from asbestos exposure to diagnosis nor disease progression after diagnosis were significantly different between mice on these diets. We conclude that vitamin D is unlikely to moderate the incidence of disease in asbestos-exposed populations or to ameliorate the pathology in patients with established mesothelioma. © 2014 Taylor and Francis Group, LLC.
