目的分析微小乳头状甲状腺癌淋巴结转移的特点与手术清扫的必要性。方法 46例微小乳头状甲状腺癌患者,分析其甲状腺癌淋巴结转移的特点,并观察颈部淋巴结清扫术的治疗效果。结果年龄、肿瘤原发灶数量、肿瘤直径、发病区域等均为微小乳头状甲状腺癌淋巴结转移的主要影响因素(P<0.05)。本组46例患者经治疗,治愈44例,治愈率为95.65%,随访期间复发2例,均经再次手术治愈,随访期间无死亡病例。结论微小乳头状甲状腺癌淋巴结转移的影响因素复杂,行颈部淋巴结清扫术治疗的治愈率与安全性均较为理想。
Objective To analyze the characteristics of lymph node metastasis in mini papillary thyroid carcinoma and the necessity of surgical dissection. Methods Forty - six patients with papillary thyroid carcinoma were analyzed for the characteristics of lymph node metastasis of thyroid carcinoma and the therapeutic effect of cervical lymphadenectomy was observed. Results The age, the number of primary tumor, the diameter of tumor and the incidence area were the main influencing factors of lymph node metastasis in minimal papillary thyroid carcinoma (P <0.05). The group of 46 patients treated, 44 cases were cured, the cure rate was 95.65%, 2 cases of recurrence during follow-up, were cured by reoperation, no deaths during follow-up. Conclusion The influencing factors of lymph node metastasis in patients with papillary thyroid carcinoma are complex, and the cure rate and safety of cervical lymph node dissection are ideal.
