Preoperative Low 25-hydroxyvitamin D Level Is Associated With Poor Prognosis of Papillary Thyroid Cancer
Research Square (Research Square)(2021)
Abstract
Abstract Purpose: To evaluate the relationship between preoperative 25-hydroxyvitamin D (25[OH]D) level and poor prognosis factors of papillary thyroid cancer.Methods: A total of 1198 patients diagnosed of papillary thyroid cancer were analyzed retrospectively. Patients were categorized into vitamin D deficiency (VDD) group and normal group according to preoperative 25(OH)D<20 ng/mL and 25(OH)D≥20 ng/mL. Differences of demographic date and clinicopathological characteristics were analyzed between two groups. Liner and logistic regression analysis to determine the effect of 25(OH)D on the established poor prognosis factors of papillary thyroid cancer were also applied.Results: We observed a negative liner correlation between 25(OH)D levels and tumor size and an independent relationship between VDD and lymph node metastasis in central area. Additionally, there was a significant correlation between preoperative 25(OH)D and thyroid-stimulating hormone (TSH) levels.Conclusions: 25(OH)D level significantly associated with certain poor prognosis factors of papillary thyroid cancer. Assessing and supplementing vitamin D may be an important addition to preoperative management of patients with papillary thyroid cancer.
