{Abstract}: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor originating from the parafollicular cells (C cells) of the thyroid gland, classified as sporadic and hereditary. Calcitonin (Ctn) secreted by the C cells is a specific serological marker for MTC, which is of great value in diagnosis, treatment and postoperative management of MTC. The effect of chemoradiotherapy and 131I therapy on MTC is limited, with surgery being the primary therapy. Given the aggressive nature and relatively poor prognosis of MTC, the reasonable surgical extent is crucial for improving cure rate and prognosis of patients. However, there are still some controversies regarding the extent of surgery for MTC. This article elaborates on the research progress and controversies of serum Ctn levels in assisting the evaluation of the extent of surgery for MTC.<BR>甲状腺髓样癌（MTC）是一种起源于甲状腺滤泡旁细胞（C细胞）的神经内分泌肿瘤，分为散发性和遗传性。C细胞分泌的降钙素（Ctn）是MTC特异性的血清学标志物，在MTC的诊断、治疗及术后管理中具有重要价值。放化疗及131I对MTC的治疗效果十分有限，手术为目前MTC的主要治疗方式。MTC侵袭性较强、预后相对较差，因此，合理的手术范围对于提高患者的治愈率及改善预后具有重要意义。然而，目前关于MTC的手术范围仍存在部分争议，现就血清Ctn水平在协助评估MTC手术范围的研究进展及争议进行阐述。.
