颈淋巴结转移是喉癌患者最重要的预后因素。对52例原发喉癌做喉全切术或部分切除术及颈清扫术患者,进行临床及标本回顾性分析。喉癌病理诊断均为鳞癌。颈清扫之淋巴结病理结果分为三类:①无病理转移;②颈淋巴结癌转移限于淋巴结内;③癌转移侵及颈淋巴结被膜外组织(ECS)。肿瘤分级:T_1者5例(9%),T_2者13例(24%),T_3者30例(56%),T_4者4例(11%);肿瘤分期:Ⅱ期者4例(7%),Ⅲ期者28例(51%),Ⅳ期者20例(42%)。比较5年存活率结果:①TNM的Ⅱ期者为68%,Ⅲ期者为62%,Ⅳ期者为53%,各期无统计学差异;T_1或T_2者为
Cervical lymph node metastasis is the most important prognostic factor in patients with laryngeal cancer. 52 cases of primary laryngeal laryngectomy or partial resection and neck dissection in patients with clinical and specimen retrospective analysis. Pathological diagnosis of laryngeal squamous cell carcinoma. Neck dissection of the pathological results of lymph nodes are divided into three categories: ① no pathological transfer; ② cervical lymph node metastasis limited to lymph nodes; ③ cancer metastasis and invasion of cervical lymph nodes outside the capsule (ECS). The tumor grade was T5 in 5 cases (9%), T_2 in 13 cases (24%), T_3 in 30 cases (56%) and T_4 in 4 cases (11% ), Stage Ⅲ in 28 cases (51%), stage Ⅳ in 20 cases (42%). Comparison of 5-year survival rate results: ①TNM stage Ⅱ was 68%, stage Ⅲ was 62%, stage Ⅳ was 53%, no significant difference between the various stages; T_1 or T_2 were
