Vıtamın D and Thyroıd Nodules in an Eastern Regıon of Turkey

Objective: There are reported associations between Vitamin D and some cancers, but the relationship in thyroid cancer has not been fully evaluated. The aim of this study is evaluate the relationship between Vitamin D levels and ultrasonographical data and cytological features of the nodules obtained by biopsy and after surgery in an eastern region of Turkey. Methods: The records of 225 patients who underwent fine needle aspiration biopsy were included in the research. Thyroid hormone, and Vitamin D levels, ultrasonograpical parameters and biopsy and surgery results of the individuals were recorded. We seeked a relationship between Vitamin D levels and also results of the nodules obtained with ultrasonography, biopsy and surgery. Results: There were no relationship between Vitamin D and ultrasonographical characteristics, fine needle aspiration biopsy and also histopathological surgery results. Conclusions: Our results showed that there were no relationship between Vitamin D and ultrasonographical characteristics, biopsy and surgery results. However although size of our group was small, we found that if the patient had a large nodule and deficient Vitamin D levels, their cytological results might be malign. So we reached a conclusion that in such patients although biopsy reveals a benign result, the procedure must be repeated.
