Vitamin D and Cancer: Current Dilemmas/Future Needs
May 7-8, 2007, Bethesda, Maryland
More than 150 researchers from the United States and around the world attended the conference "Vitamin D and Cancer: Current Dilemmas/Future Needs" in May on the NIH Campus in Bethesda, MD. The conference addressed gaps in the literature on the role of vitamin D alone and in combination with genetic factors and other nutrients in preventing cancer.

Participants focused on the following questions that could be made part of a research agenda for the future:
- How strong is the evidence that vitamin D status is related to cancer risk?
- How has nutrigenetics advanced our understanding of the relationship between vitamin D and cancer risk?
- What other genes determine the response to vitamin D?
- What are the important dietary components that modify the effect of vitamin D?
- What information have preclinical models provided about the relationship between vitamin D, calcium, and cancer?
Compelling evidence continues to accumulate on vitamin D's protective effects against cancer. Epidemiologic studies suggest that a deficiency of the vitamin is associated with increased risk for colorectal, prostate, and breast cancer, and perhaps for other cancers. The conference provided the opportunity to consider the state of the science on the vitamin and research that needs to be tackled next to more clearly understand its role in cancer risk.

Among the participants were EGRP-funded investigators who provided the epidemiologic perspective on the role of vitamin D and cancer risk, including Cedric Garland, Dr.P.H., University of California, San Diego; Edward Giovannucci, M.D., Sc.D., Harvard University; Sue Ingles, Dr.P.H., University of Southern California; Thomas Rohan, M.D., Ph.D., Albert Einstein School of Medicine; Martha Slattery, Ph.D., University of Utah; and Walter Willett, M.D., Dr.P.H., Harvard University.
A publication summarizing the proceedings was published in a supplement to the August 2007 issue of Nutrition Reviews:
Davis CD, Hartmuller V, Freedman M, Hartge P, Picciano MF, Swanson CA, Milner JA. Vitamin D and Cancer: Current Dilemmas and Future Needs. Nutr Rev. 2007; 65 (Supplement 1): 71-74.
The workshop organizers were EGRP's Virginia (Ginny) Hartmuller, Ph.D., R.D., Acting Chief, Modifiable Risk Factors Branch; Patricia Hartge, Sc.D., DCCPS and DCEG; Cindy Davis, Ph.D., and John Milner, Ph.D., DCP; D. Michal Freedman, Ph.D., DCEG; and Mary-Frances Picciano, Ph.D., and Christine Swanson, Ph.D., ODS.
The workshop was cosponsored by NCI's Division of Cancer Control and Population Sciences (DCCPS), of which the EGRP is a part; the Division of Cancer Prevention (DCP); Division of Cancer Epidemiology and Genetics (DCEG); and the NIH Office of Dietary Supplements (ODS).
A follow up conference was held on September 5-6, 2007 focusing on an evidence-based review of Vitamin D in food. Further details regarding the September 2007 conference can be obtained through the NIH Office of Dietary Supplements Web site.
