目的:探讨甲状腺微小癌的临床诊断和治疗方法。方法:对诊断明确的47例甲状腺微小癌进行回顾性分析。结果:术前仅12例疑为甲状腺癌,余35例均于术中冰冻和术后病理确诊。34例合并甲状腺良性疾病,伴颈淋巴结转移3例。47例中有11例术后无瘤生存时间≥10年,24例术后无瘤生存时间≥5年。结论:甲状腺微小癌术前不易确诊,且易漏诊,对甲状腺良性疾病手术时应仔细触诊,对可疑结节行冰冻切片。首次手术应行患侧腺叶及峡部切除术,有淋巴结转移者行功能性淋巴结清扫术可取得较好疗效。
Objective: To investigate the clinical diagnosis and treatment of thyroid microcarcinoma. Methods: A retrospective analysis of 47 cases of diagnosed thyroid microcarcinoma was made. Results: Only 12 cases of preoperative thyroid cancer suspected, more than 35 cases were intraoperative frozen and postoperative pathological diagnosis. 34 cases of benign thyroid disease, with cervical lymph node metastasis in 3 cases. Of the 47 patients, 11 had a postoperative tumor-free survival of ≥10 years and 24 had a postoperative tumor-free survival of ≥5 years. Conclusion: The thyroid microcarcinoma is not easily diagnosed preoperatively and is easily misdiagnosed. Palpation of thyroid benign diseases should be carefully palpated and the suspicious nodules should be frozen sectioned. The first operation should be affected by ipsilateral lobectomy and isthmus, lymph node metastasis line functional lymph node dissection can achieve better results.
