Researchers Say More Aggressive Vitamin D Supplementation Needed In Obese Cancer Patients

Body mass index (BMI) should be taken into account when assessing a cancer patient"s vitamin D status, according to researchers at Cancer Treatment Centers of America (CTCA), who found that obese cancer patients had significantly lower levels of vitamin D compared to non-obese patients. The association between vitamin D and obesity remains unsettled with studies reporting conflicting findings on the relationship between the two. This association assumes even greater importance in cancer because of the alleged role of vitamin D in cancer. "Currently, the dietary recommendations for vitamin D do not take into account a patient"s BMI," said Carolyn Lammersfeld, national director of nutrition for CTCA and a principal investigator in the study. "We investigated the relationship between vitamin D and BMI in a large sample of cancer patients and found that as BMI groups increased from normal to overweight or obese classifications, there was a significant decrease in vitamin D." The researchers evaluated a group of 740 cancer patients seen at CTCA from January 2008 to June 2008. Of the 740 patients, 303 were male and 437 female, with a mean age at presentation of 55.7 years (SD = 10.2). The mean BMI was 27.9 kg/m2 (SD = 6.7). The most common cancers were lung (134, 18.1%), breast (131, 17.7%), colorectal (97, 13.1%), pancreatic (86, 11.6%), prostate (45, 6.1%) and ovarian (39, 5.3%). The mean vitamin D (serum 25(OH)D) was 21.9 ng/ml (SD = 13.5). The study concluded that obese cancer patients (BMI >=30 kg/m2) had significantly lower levels of vitamin D compared to non-obese patients (BMI About Cancer Treatment Centers of America Founded in 1988, Cancer Treatment Centers of America (CTCA) is a national network of hospitals providing a comprehensive, fully integrative approach to cancer treatment.
