鼻咽癌TNM分期标准的新建议

A NEW PROPOSAL ON THE TNM STAGING SYSTEM OF NASOPHARYNGEAL CARCINOMA

将1969年2月—1981年12月我院677例鼻咽癌的临床表现,放疗后存活情况应用TNM分期进行探讨,并对我院1985年12月～1991年12月342例鼻咽癌CT扫描结果分析。CT扫描后发现肿瘤向鼻咽腔外侵犯者较临床诊断增加,T_1,T_2分别从8.48％和54.68％减至0.88％和26.31％,而T_3和T_4分别从34.21％和2.63％上升至59.65％和13.16％。因此,必须特别强调现代影象学在鼻咽癌TNM分期标准中的重要作用,提出了鼻咽癌TNM分期标准的新建议,并与1979年长沙会议和1977年日本京都会议鼻咽癌分期法进行了比较。

A new clinical staging system based on 677 patients with nasopharyngeal carcinoma (NPC) as treated from 1969 to 1981 is proposed. Comparison of the results of CT scaned with that by clinical examination of 342 untreated NPC patients admitted from 1985 to 1991 showed that in the pri- mary lesion (T) the percentage of T1 and T2 were reduced from 8. 47% and 54. 67% to 0. 87% and 26. 31% by CT scan. The pecent age of T3 and T4 were increased from 43. 21% and 2. 63% to 59. 64% and 13. 16%. The authors emphasize the importance of CT scan in the staging of NPC. Accordingly a new proposal on the staging system of NPC is presented and comparison of Changsha, Kyoto and this new staging system is discussed.
