喉癌喉前淋巴结转移

Prelaryngeal lymph node metastasis

回顾性调查1865例行全喉切除的喉癌病例．发现120例喉癌有喉前淋巴结，其中24例发生喉前淋巴结转移。非转移性喉前淋巴结最大直径从0．2cm大小到1cm左右不等，转移性喉前淋巴结从0．2cm到最大直径1．9cm。喉前淋巴结转移率为1．3％．其中声门上癌、声门癌、声门下癌和跨声门癌的喉前淋巴结转移率分别为0．39％、0．73％、5．02％和2．55％。喉前淋巴结转移与细胞分化无关，与喉癌原发部位及肿瘤分期有关，声门下癌或侵犯声门下区的喉癌较声门上癌和声门癌易发生喉前淋巴结转移，跨声门侵犯的喉癌较声门上癌易发生喉前淋巴结转移；T3、T4期喉癌，较T1、T2期喉癌易发生喉前淋巴结转移；有喉前淋巴结转移的喉癌．易发生颈侧淋巴结转移。

Eighteen hundred and sixty five patients with laryngeal squamous cell carcinoma treated by laryngectomy were reviewed. One hundred twenty cases with prelaryngeal lymph nodes were identified, 24 of them with prelaryngeal lymph nodes metastasis. The metastasis incidences of prelaryngeal lymph node were 0. 39%, 0. 37%, 0. 02% and 2. 55% respectively of supraglottic, glottic, subglottic and transglottic carcinomas.Prelaryngeal lymph node metastasis was associate with slies and T stage. Subglottic or advanced carcinomas were easier to develops prelaryngeal lymph node metastasls. Laryngeal squamous cell carcinomas with prelaryngeal lymph node metastasis tended to develope cervical lymph node metastasis.
