目的 追踪随访186例甲状腺微小乳头状癌(Papillary Thyroid Microcarcinoma,PMC)患者术后5年及10年的肿瘤复发率、生存率、及术后并发症,探讨不同手术方式对治疗甲状腺微小乳头状癌预后。方法 临床资料为1993—2003年收治的186例甲状腺微小乳头状癌患者,102例行患侧甲状腺大部分切除术(Ⅰ组),84例行患侧甲状腺全切术+峡部切除+对侧甲状腺大部分切除+中央区淋巴结清扫术(Ⅱ组)。结果 Ⅰ组患者术后5年及10年期间肿瘤复发率、生存率与Ⅱ组差别无统计学意义(P﹥0.05),对比I组,Ⅱ组患者术后发生甲状腺及甲状旁腺功能低下的发生率较高,且差别有统计学意义(P﹤0.05)。结论 甲状腺微小乳头状癌预后良好,实行患侧甲状腺大部分切除术对治疗甲状腺微小乳头状癌是安全可行的。

Objective To follow-up 186 cases of papillary thyroid microcarcinoma and analyse their tumor recurrence rate、survival rate and complicationg after 5 and 10 years postoperation, to investigate prognosis of papillary thyroid microcarcinoma from different operation approaches. Methods 186 cases of papillary thyroid microcarcinoma were from 1993 to 2003. All the patients were divided into two groups,102 cases(group Ⅰ) performed with resection of the majority of thyroid gland, and 84 caces(group Ⅱ) performed with total thyroidectomy, thyroidectomy+isthmus thyroidectomy+contralateral thyroid lobectomy+central lymph node ablation. Results The recurrence and survival rates after 5 and 10 years were not significantly different between the two groups, but compared group Ⅰ, the incidences of hypocalcemia and hypothyroidism were higher in group Ⅱ(P<0.05). Conclusion Papillary thyroid microcarcinoma had better prognosis. Resection of the majority of thyroid gland treating papillary thyroid microcarcinoma is safe and feasible.
