摘要
本文60例鼻咽癌患者进行放疗前鼻咽部CT扫描,分析CT扫描对鼻咽癌临床分期的作用.结合CT扫描图象分析,使原常规临床分期发生了较大变化.T_0从1.6％下降为0％;T_1、T_2分别从16.6％、30％下降至5％、10％;而T_3、T_4分别由31.6％、20％上升为35％、50％.60例中常规临床分期与结合CT扫描分期相符者22例(36.7％),T分期升级者38例(63.3％).结合CT扫描可提示鼻咽癌临床分期的准确性,使放疗方案设计更为合理.
From January 1990 to December 1991,60 patients with nasopharyngeal carcinoma were scanned with GE9000 CT scanner. CT image upgraded the clinical staging in 38 cases(63. 3%). The incidence of stage T0 was reduced from 1.6% to 0%,T1 from 16. 6% to 5% ,and T2 from 30% to 10%. Frequencies of T3 and T4,however,were increased from 31. 6% to 35% and from 20% to 50%respectively. It is suggested that CT can find minimal bone destruction and tumor invasion and in turn raise the accuracy of staging.
