甲状腺髓样癌的影像学进展

The Imaging Progress of Medullary Thyroid Carcinoma

甲状腺癌是较常见的内分泌系统肿瘤之一,甲状腺髓样癌(medullary carcinoma of the thyroid, MTC)是来源于滤泡旁细胞(C细胞)的肿瘤,占据甲状腺癌的1%~5%。MTC与其他类型的甲状腺癌相比,在生物学行为以及预后方面存在明显差异,在临床上较为罕见,但其恶性程度高,且对放化疗不敏感,因而早期确诊MTC具有非常重要的临床意义。MTC的术前诊断以及术后肿瘤复发诊断主要依靠影像学检查,特本文就现有影像学检查对MTC的诊断及其研究进展进行综述。

Thyroid cancer is one of the most common endocrine system tumors. Medullary carcinoma of the thyroid (MTC) is a tumor derived from parafollicular cells (C cells), which accounts for 1% to 5% of thyroid cancers. Compared with other types of thyroid cancer, MT has obvious differences in biological behavior and prognosis. It is relatively rare in clinical practice, but its malignant degree is high, and it is not sensitive to radiotherapy and chemotherapy. Therefore, early diagnosis of MTC has very important clinical significance. The preoperative diagnosis of MTC and the diagnosis of postoperative tumor recurrence mainly rely on imaging examinations. This article reviews the existing imaging examinations for the diagnosis of MTC and its research progress.
