甲状腺乳头状微小癌124例的治疗和预后分析

目的 探讨甲状腺乳头状微小癌的治疗和预后.方法 回顾性分析1990年1月1日-1999年12月31日间在中山大学肿瘤防治中心头颈科接受治疗的124例甲状腺乳头状微小癌的临床和随访资料,对其进行Kaplan-Meier法单因素分析和Cox比例模型多因素分析.结果 124例甲状腺乳头状微小癌患者10年和15年生存率分别为94.9%、92.5%;单因素分析提示首诊时年龄≥35岁、有远处转移显著影响甲状腺乳头状微小癌患者的预后(均P＜0.05).而性别、是否为术中偶然发现、原发癌灶大小、淋巴结转移、是否为术后复发、手术范围等与患者预后无显著相关;多因素分析发现患者年龄≥35岁是影响甲状腺乳头状微小癌预后的独立因素(P=0.045).结论 甲状腺乳头状微小癌患者预后较好,但年龄≥35岁或有远处转移者预后较差.

Abstract：

Objective To investigate the treatment and prognosis of patients with papillary thyroid microcarcinoma. Methods The clinical and following-up data of 124 patients with papillary thyroid microcarcinoma treated at the Department of Head and Neck Surgery of Cancer Centre, SUN Yat-sen University from Jan 1990 to Dec 1999 were analyzed retrospectively for mortality and survival rate ( KaplanMeier). A multivariate analysis was performed in these patients by Cox proportional hazard model. Results The overall 10-year and 15-year survival rate of all 124 patients with papillary thyroid microcarcinoma were 94.9% and 92.5% respectively. The univariate analysis showed the prognostic factors significantly influencing the survival of patients included age (being worse for those of 35 years and older) at presentation, and the status of distant metastasis ( all P ＜ 0. 05 ) , while gender, incidentally found at surgery, the size of primary tumor, the status of neck lymph node metastasis, recurrence after a primary resection, and the extent of surgical resection did not significantly effect the prognosis. Multivariate analysis showed the age more than 35 years at presentation was an independent risk factor indicating worse prognosis (P = 0. 045 ). Conclusioas The prognosis of patients with papillary thyroid microcarcinoma is satisfactory, but that is poor for those patients 35 years old and up at presentation and with distant metastasis.
