A recent study, published in Cancer Epidemiology, Biomarkers & Prevention is the second study to show that high levels of circulating vitamin D binding protein (DBP) in the blood is associated with a reduced risk of developing renal cell carcinoma (RCC).
The study included 39,371 individuals who provided a blood sample and were free of cancer at the time of blood collection. In 2009, 87 of these people were determined to have a primary diagnosis of RCC from a questionnaire and their medical records.
The researchers found that high levels of serum DBP were inversely associated with RCC risk. Those people with the highest levels of DBP were found to be younger, more likely to be female, had a lower BMI, and were more likely to be non-smokers.
