本院从1978年3月至1980年3月期间用电子直线加速器(10 MV X线)治疗66例食管癌及同期不加选择的~(60)Co治疗76例食管癌进行对比分析,现报道如下: 临床资料病例的选择条件是:(1)所有病例均经X片诊断;(2)125例(88％)经脱落细胞及病理诊断证实,其余17例(12％)无病理诊断;(3)除2例术前放疗肿瘤量为3850 cGy外,余均在4000 cGy以上,大部分在6500～7500cGy之间。一、性别与年龄 10 MV X线组(下称加速器组)男52例,女14例,~(60)Co γ线组(下称钴组)男68例,女8例,两组共男120例,女22例,男与女之比为5.45:1,与上海报告的5.4:1相仿。
From March 1978 to March 1980, our hospital used a linear accelerator (10 MV X-ray) to treat 66 cases of esophageal cancer and 76 cases of esophageal cancer treated with unselected ~(60)Co during the same period. The following are the conditions for the selection of clinical data: (1) All cases were diagnosed with X-ray; (2) 125 cases (88%) were confirmed by exfoliated cells and pathological diagnosis, and the remaining 17 cases (12%) had no pathological diagnosis; ( 3) Except for 2 cases of 3850 cGy of tumor before radiotherapy, the rest was above 4000 cGy, most of which was between 6500 and 7500 cGy. I. Gender and age 10 MV X-ray group (hereinafter referred to as accelerator group) 52 males and 14 females, ~(60)Co γ-ray group (hereinafter referred to as cobalt group) 68 males and 8 females, males in two groups In 120 cases and 22 females, the male-to-female ratio was 5.45:1, similar to the 5.4:1 reported by Shanghai.
