舌鳞癌颈部淋巴结转移的临床分析

A Clinical Study on Patients with Cervical Lymphnode Metastasis of Tongue Squamous Cell Carcinoma

目的 探讨舌鳞癌颈淋巴转移的发生规律以及对CN0 (临床不怀疑转移 )患者的治疗原则。方法 对本院 1991— 2 0 0 2年间 73例舌鳞癌患者的临床资料进行回顾性分析研究。结果 舌鳞癌总体转移率为 46 5 8% ,CN0 患者的颈淋巴结隐匿转移率为 2 9 0 3 % ,舌鳞癌隐匿性转移与肿瘤T分期密切相关。结论 舌鳞癌颈部转移率及CN0 患者淋巴结隐匿性转移率均较高 ,临床上应根据原发灶的大小等因素综合考虑 ,研究合理的治疗方案 ,可提高其颈部控制率和生存率。

Objective To investigate the regularity of cervical lymphnode metastasis of tongue squamous cell carcinomas and the treatment principles to the CN 0 patients. Methods By retrospective analysis of 73 cases with squamous cell carcinoma of oral cavity. All the cases underwent neck dissection from 1991 to 2002. Results The total rate of cervical lymphnode metastasis of tongue squamous cell carcinoma was 46.58%; The rate of occult metastasis was 26.03%. The incidence of occult metastasis was closely related to the staging of T. Conclusion This study revealed that the therapy region of the tongue squamous cell carcinoma should be based on the carefully clinical examination of primary lesion according to the size and the compositive analysis of cervical lymphnode. Elective neck dissection may decrease the ratio of metastasis of tongue squamous cell carcinoma.
