分化型甲状腺癌(differentiated thyroid carcinoma,DTC)大多恶性程度低、生长缓慢、预后好,完善治疗后其10年生存率在90%以上[1]。然而,有6%~13%的肿瘤可能发生周围组织或器官的侵犯,此常由原发肿瘤直接侵犯或中央区淋巴结转移侵犯引起,受累部位包括颈前带状肌(53%)、喉返神经(47%)、气管(37%)、颈鞘(30%)、食管(21%)、喉(12%)等,此类患者的10年生存率也因此下降至45%[2]。McCaffrey等[3]认为,喉、食管及气管的管腔侵犯是晚期DTC患者死亡的主要原因,其中食管/气管受累与否与患
Differentiated thyroid carcinoma (DTC) most of the low degree of malignancy, slow growth, good prognosis, and its 10-year survival rate after percutaneous coronary intervention in more than 90% [1]. However, 6% to 13% of the tumors may be infiltrated by surrounding tissues or organs. This is often caused by direct invasion of the primary tumor or invasion of the central lymph node metastasis. The affected sites include the anterior cervical sphenoid muscle (53%), (47%), trachea (37%), neck sheath (30%), esophagus (21%), larynx (12%), etc. The 10-year survival rate of these patients is therefore reduced to 45% [2]. McCaffrey et al [3] that laryngeal, esophageal and tracheal lumen invasion is the leading cause of death in patients with advanced DTC, esophageal / trachea involvement or not with the affected
