食管癌放疗与放化疗综合治疗的疗效比效

目的 :探讨影响食管癌疗效的因素。材料与方法 :对 1993年 1月至 1999年 9月间病理和临床资料完整的 2 0 0例食管癌进行临床分析。所有病例均为初次治疗 ,经病理证实 ,鳞癌 196例 ,小细胞未分化癌 2例 ,腺癌 1例 ,腺鳞癌 1例 ,按UICC1987分期标准分期 ,原位癌 1例 ,Ⅰ期 3例 ,Ⅱ期 47例 ,Ⅲ期 12 7例 ,Ⅳ期 2 2例 ,全部病例中单纯放疗 (简称单放组 ) 113例 ,放化综合治疗 (简称综合组 ) 87例 ,所有病例均行60 Co或 6MVX线外照射 ,常规设野 ,常规分割 ,1 8～ 2Gy/次·天 ,5次 /周 ,DT5 0～ 73Gy ,有锁骨上淋巴结转移者加照锁骨上区 ,DT5 0～ 70Gy ,综合组多数在放疗结束后给予化疗 ,每 3～ 4周为一周期 ,共 2～ 5个周期不等 ,方案多为DDP +5 -Fu ,有的病例加PYM和或CF。统计分析方法 :生存率分析用Kaplan -MeierMethod ,生存差异性检验采用Log -ranktest,多元回归分析采用CoxProportionalHazardsMode。结果 :随访至 1999年 12月 31日 ,中位随访时间 14个月。 (1～ 80月 ) ,1、 3、 5年生存率综合组分别为 6 0 %、 2 2 %、 10 % ,单放组为 30 %、 11%、 2 % ,两组生存曲线的差异有显著性 ,P =0 0 470 ;1、 3、 5年无远处转移生存率综合组和单放组分别是 80 % ,5 5 % ,37% ;6 0 % ,2 1% ,8% ,两组生存曲线

A Comparison of Therapeutic Results between Radiotherapy Alone and Combined Chemoradiotherapy in Patients with Esophageal Cancer

Objective:To investigote the factors influencing the therapeutic results from treating carcinoma of the esophagus.Methods:Two hundred patients with carcinoma of esophagus proved pathologically were reviewed,and in these patients,113 patients received radiation therapy alone,and 87 received chemoradiotherapy (combined treatment).The data were analyzed with Kaplan-Meier method and log-rank test.Results:1,3,5-year disease-free survival with combined treatment and radiotherapy alone were 60%,22% and 10% vs.30%,11% and 2%,respectively, P =0 047,with statistical significance.Howeven,1,3,5-year distant metastases-free survival with combined treatment was significantly higher than that of radiotherapy alone,(80%,50%,and 37% vs.60%,21%,8%,respectively), P =0 0134.Conclusions:The rate of survival from combined treatment was better than that of radiotherapy alone.Treatment methods,therapeutic dosage applied and the clinical stages of the tumor were important prognostic factors.
