原发性声门下肿瘤应与扩展至声门下的声带肿瘤相区别。原发于声门下的上皮癌极为罕见。本文报道了原发性声门下癌的观察和治疗结果。作者们在1980年前的15年间共见到2,180例喉癌患者,仅22例(1%)为原发性声门下癌,其中6例曾在别处作过治疗故未列入,余16例中除3例系近几年内治疗者外其余13例患者均随访5年以上。16例中男13,女3例。年龄33～77(平均60)岁。有声嘶,咯血及呼吸窘迫症状。按TNM分期T_1 1例,T_2 2例,T_3 5例,均未见转移;T_4 8例,其中T_4N_1和T_4N_2各2例。对T_3和T_4的13例患者均早期行全喉切除,3例T_1和T_2期者作部分喉切除。对明显淋巴结转移者还作了根治性颈廓清术。1例死于术后的上消化道出血。3例T_1和T_2期患者未见局部复发。
Primary subglottic tumors should be distinguished from vocal cord tumors that extend below the subglottic. Epithelial cancers that originate under the glottis are extremely rare. This article reports the observation and treatment of primary subglottic cancer. The authors saw 2,180 cases of laryngeal cancer in the 15 years before 1980. Only 22 cases (1%) were primary supraglottic carcinomas, of which 6 had been treated elsewhere and were not included. The remaining 16 cases In addition to the 3 cases in the treatment of 13 patients in the remaining 13 cases were followed up for more than 5 years. In 16 cases, there were 13 males and 3 females. Age 33 to 77 (average 60) years old. There are voices, hemoptysis, and respiratory distress symptoms. According to TNM staging T_1 1 case, T_2 2 cases, T_3 5 cases, no transfer was seen; T_4 8 cases, T_4N_1 and T_4N_2 each had 2 cases. Thirteen patients with T_3 and T_4 were treated with total laryngectomy, and 3 patients with T_1 and T_2 had partial laryngectomy. Radical neck dissection was also performed for patients with significant lymph node metastases. One patient died of postoperative upper gastrointestinal bleeding. No local recurrence was found in 3 patients with T 1 and T 2 phases.
