摘要目的 探讨成人喉乳头状瘤恶变的临床特征、病理特点及远期治疗效果.方法 对62例成人喉乳头状瘤患者手术前后的临床及病理资料进行分析.结果 62例成人喉乳头状瘤中发生恶变17例,其中术前经1次病理检查确诊者5例(29.4%),经2～7次病理检查确诊8例(47.1%),术后确诊4例(23.5%);其早期病理特征是部分区域恶变,而其他部位还保持着喉乳头状瘤的特点.其中声门型14例(T1N0M06例,T2N0M05例,T3N0M0 2例,T3N1M0 1例),声门上型3例(T4N0M01例,T4N1M02例).行全喉切除术4例,喉部分切除术13例,术后1年内全部拔管,拔管率100%.3年、5年生存率分别为88.2%(15/17)、76.5%(13/17).结论 必要时反复活检是术前确诊成人喉乳头状瘤恶变的重要方法,彻底的手术切除是其治疗的重要手段.

abstractsObjective To explore the malignant change of laryngeal papilloma in adults, especially its pathological figures, clinical characters and long -term results.Methods Analysis was made for the pre - and post - operated clinical and pathological dates of 62 laryngeal papilloma cases.Results Malignant changes had been found in 17 cases.Among these cases, 5 were diagnosed after 1 biopsy, 8were diagnosed after 2 up to 7 biopsies, 4 were diagnosed after surgeon.It was the character of earlier pathological changes that there were malignant changes in part areas, whereas normal papilloma in the other areas of the laryngeal neoplasm.There were 14 of 17 cases whose malignant changes were in glottis (T1N0M0 6 cases, T2N0M0 5 cases, T3N0M0 2 cases, T3N1M0 1 case).Malignant changes of the other 3cases were in supraglottic area(T4N0M0 1 case, T4N1M0 2 cases).Total laryngectomy was performed for 4 cases, and partial laryngectomy was selected for other 13 cases.The decannulation rate was 100% after 1 - year' s follow - up.The overall 3 - years and 5 - years survival rates were 88.2%(15/17)and 76.5%(13/17)respectively.Conclusions It is important to repeat biopsies if necessary to avoid fail to report the malignant change before surgeon.The key to cure it is completely removal of the tumor.
