声门下区喉癌的临床特点与手术治疗

目的　探讨声门下区喉癌的临床特点和治疗手段。方法　 7例 46～ 74岁 (平均 62 5岁 )原发声门下区喉癌。分期为T2 N0 M0 2例 ,T3 N1M0 3例 ,T3 N0 M0 1例 ,T4 N1M0 1例。对其临床特点、治疗方法、预后等方面进行分析。结果　声门下区癌发病率低 ,气管造口复发率高 ,声门下区癌T3 、T4 病变者宜全喉切除。T1、T2 病变者作声门下区部分切除预后同样好。结论　声门下区癌易向气管旁淋巴结、喉前淋巴结转移。术中应注意这些淋巴结的清扫。术后放疗对肿瘤的复发和转移是一种有效的辅助治疗。

Study on the Clinical Features and Treatment of Subglottic Cancer

Objective The clinical features and treatment of subglottic cancer were studied.Methods There were 7 males with subglottic cancer, ranging in age from 46 to 72 (mean age:62.5 years). The stage of TNM was T 2N 0M 0 in 2, T 3N 1M 0 in 3, T 3N 0M 0 in 1 and T 4N 1M 0 in 1. The clinical features,treatment and prognosis of subglottic cancer were analysed.Results The mobidity of subglottic cancer was low. Tracheostomal recurrences were often found. Total laryngectomy is to be performed for T 3,T 4 lesion and partial laryngectomy is to be performed for T 1,T 2 lesion.Conclusions The mestastasis of subglottic cancer often goes to prelaryngeal lymph node and paratraches lymph node. During the operation, those lymph nodes should be dissected. Postoperative radiotherapy was an effective adjuct for recurrence and metastasis of the tumor.
