摘要
目的探讨食管癌CT表现及其对放疗的预测价值。方法回顾性分析182例食管癌的临床资料,并采用Kaplan-Meier法进行生存分析。182例均接受放疗,采用8MVX射线照射,DT64～68 Gy,32～34次,42～46天。结果CT检查可显示肿瘤强化程度、外侵情况、病灶长度、最大直径。2年局部控制率中度强化者高于轻度强化者(73.3%和54.3%,χ2=6.0,P<0.05),边缘规则者高于边缘不规则和明显外侵者(77.8%、67.7%和48.5%;χ2=6.87,P<0.05;χ2=6.04,P<0.05),病变短者高于病变长者(χ2=12.3,P<0.05)。肿瘤直径与2年局部控制率无显著相关性(χ2=1.4,P>0.05)。结论食管肿瘤强化程度低、边缘不规则或外侵、病变长度越长者局部控制率越低,据此可以粗略判断患者预后。
Objective To explore esophageal carcinoma CT expression and its prognostic value of radiotherapy.MethodsRetrospective analysis of record information of 182 cases of esophageal carcinoma patients,and the Kaplan-Meier method of survival analysis.182 patients received radiotherapy,using 8 MVX irradiation,DT 64～68 Gy,32～34,42～46 days.Results The CT examination showed tumor enhancement degree,invasion,focal length,maximum diameter.Within 2 years,the local control rate of moderate enhancement was higher than that of the mild enhancement（73.3% and 54.3%,χ2=6.0,P0.05）,rule edge was higher than that of irregular edge and obvious invaders（77.8%,67.7% and 48.5%;χ2=6.87,P 0.05;χ2=6.04,P0.05）,shorter lesions was higher than that of elderly lesions（χ2=12.3,P0.05）.Tumor diameter and 2 years local control rate had no significant correlation（χ2=1.4,P0.05）.Conclusion As the esophageal tumor enhancement degree is low,margin is irregular or foreign invasion,the lesion length is more elderly,local control rate is lower.It can be used to roughly judging prognosis.
