Relationship of Vitamin D Levels in Thyroid Malignancy

Vitamin D has been reported in several studies to have antiproliferative, anti-apoptotic and pro-differentiating effects in several tumor types. The role of vitamin D in the incidence and/or progression of thyroid malignancy remain largely unknown. We performed a retrospective chart review of postoperative 25-hydroxyvitamin D levels from 255 subjects receiving total (n=197) or completion (n=58) thyroidectomy for benign (n=190) and malignant (n=65) disease at the University of Arkansas for Medical Sciences between October 2005 and July 2013. No significant difference (P = 0.72) was observed between postoperative 25-hydroxyvitamin D levels in subjects with malignant pathology (median 25 ng/mL; range 21-37 ng/ml) versus benign pathology (median 27 ng/ml; range 19.5-35 ng/ml). In our limited study, there was no correlation between postoperative 25-hydroxyvitamin D status and pathological findings in subjects undergoing thyroidectomy.
