作者分析某医院1954—1971年的声门上鳞癌431例,这次观察限于病人的病变在技术上为可切除者。重点分析放疗代替部分喉切除的效果,并选择病人最宜以手术及术后有计划的放疗者。 147例接受喉部放疗,其病变为T_1及T_2;舌骨上会厌部及杓会厌皱襞有选择的外生型T_3病变;有选择的舌骨上会厌外生型T_4病变。喉部病变获得较满意控制及保持正常发声者为88.5％的T_1病变至60％的T_4病变。对以下二组曾比较其疗效:仅用手术治疗者,其无瘤迹象率为37％;手术并用术后放疗者,无瘤迹象率为63％,效果较仅用手术治疗者
The authors analyzed 431 cases of supraglottic squamous cell carcinoma in a hospital from 1954 to 1971. This observation was limited to patients whose lesions were technically resectable. Focus on the analysis of the effect of radiotherapy instead of partial laryngectomy, and select patients who are most suitable for surgery and postoperative planned radiotherapy. Among 147 patients who underwent laryngeal radiotherapy, the lesions were T_1 and T_2; the epiglottis and epiglottis folds of the hyoid bone had selective exogenous T_3 lesions; and the epiglottis exophytic T_4 lesions were selected. Laryngeal lesions with satisfactory control and maintaining normal vocalization were 88.5% T_1 lesions to 60% T_4 lesions. The efficacy of the following two groups was compared: the rate of no tumor was only 37% for those who only had surgery; the rate of no tumor was 63% when the patients were treated with postoperative radiotherapy.
