Should Calcitonin Be Measured in Every Thyroid Nodule?
There are controversial suggestions in the literature about the routine measurement of calcitonin (Ct) in thyroid nodules. Barriers in front of measuring routine serum calcitonin are cost-effectiveness and the possibility of having elevated serum Ct in the absence of medullary thyroid carcinoma (MTC). Here we report a sporadic MTC patient with negative fine needle aspiration biopsy (FNAB) result whose diagnosis was made by preoperative calcitonin measurement. As we perform routine Ct measurement before surgery, the surgeon becomes aware of the MTC earlier, and this gives the opportunity of making an appropriate surgical procedure which is crucial for patients’ outcome.
