鼻咽癌分期的研究──评’92福州分期标准

Evaluation of the TNM staging system for nasopharyngeal carcinoma ( NPC )

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) .
