摘要
研究鼻咽癌分期。材料与方法首次放疗前经CT扫描检查的鼻咽癌204例,1979年长沙分期法和1992年福州分期法进行评价。结果本组随访率为94.6%,5年生存率为52.2%。按’92福州分期法本组各项分布是:Ⅰ期2.5%,Ⅱ期22.1%,Ⅲ期48.5%,Ⅳ期24.0%,Ⅳb期2.9%:各期5年生存率分别是80%,76.2%,52.7%,43.7%和0%。结论作者建议:(1)将原发肿瘤局限在鼻咽腔者列为T1。(2)将Ⅳ期分为Ⅳ。期(T4或N3)和Ⅳb期(任何T,任何N,M1)。
Purpose To evaluation the TNM staging system for nasopharyngeal carcinoma ( NPC ) . Materials and Methods Two - hundred and four patients with NPC with computed tomography ( CT ) examined prior to their primary radiotherapy were collected to evaluate the staging systems for NPC recommended by Changsha Conference in 1979 ( ' 79 system) and that by Fuzhou conference in 1992 ( ' 92 system) . Results The overall 5 - year survival rate of this group was 52 . 2 % clinically staged by ' 92 system. The staging distributions were as follows : 2 . 5 % in stage I , 22 . 1 % in stage , 48 . 5 % in stage , 24 % in stage and 2.9% instage b.The5- year survival rates ranged from 80% 76.2% ,52.7%,43.7% to 0% Conclusion The authors suggest : ( 1 ) primary lesions limited in nasopharyngeal cavity be ranked as T1: (2)stage IV be divided into stage a (T4 or/and N3. and M0 ) and b( M1 and any T, any N) .
