作者将４９例甲状腺分化癌作一回顾性分析，对甲状腺切除范围，颈淋巴结清扫和术后辅助治疗作一扼要探讨。（１）为了提高生存率，降低复发率和避免并发症，最理想的术式是甲状腺几乎全切除术。（２）原发肿瘤直径超过１．５ｃｍ者无论术前和术中是否摸到肿大淋巴结，均需作改良淋巴结清扫。（３）原发病灶如已完全切除而无甲状腺外侵犯者，无须作预防性放射治疗。放射性碘的应用只限于无法完全切除的肿瘤或能摄碘的远处转移病灶。此外，术后常规用甲状腺激素辅助治疗以抑制ＴＳＨ。
The authors performed a retrospective analysis of 49 cases of thyroid differentiation cancer and discussed the scope of thyroidectomy, cervical lymph node dissection, and postoperative adjuvant therapy. (1) In order to improve the survival rate, reduce the recurrence rate and avoid complications, the most ideal surgical method is almost complete thyroidectomy. (2) No matter whether the diameter of the primary tumor is more than 1.5cm, no matter if it touches the enlarged lymph nodes before or during the operation, the lymph node dissection needs to be improved. (3) If the primary lesion has been completely resected without thyroid invasion, no preventive radiotherapy is required. The use of radioactive iodine is limited to tumors that cannot be completely removed or distant metastatic lesions that can take up iodine. In addition, postoperative thyroid hormone assisted treatment is routinely used to suppress TSH.
