Long-term Outcome of Reoperations for Medullary Thyroid Carcinoma

Background Most patients with medullary thyroid carcinoma (MTC) have persistent disease after primary surgery, as evidenced by calcitonin elevation. Previous reports showed that reoperation on selected patients yields immediate calcitonin normalization in one-third of patients. Long-term follow-up data are needed to assess the outcome in such patients. This report aims to provide 8– to 10–year follow-up on reoperations for persistent or recurrent MTC.
