1976年1月~1984年12月,放射治疗(肿瘤量在40Gy以上)住院食管癌患者1110例,其中男性778例,女性332例。全部病人均采用60Co体外照射,肿瘤量为50Gy~70Gy5周~7周。病人均随访5年以上,随访率为98,3%。1年、3年、5年生存率分别为55.9%、20.1%、13.8%。放射治疗效果与患者年龄、病变部位、病变长度、梗阻程度、放疗后病灶改善程度和肿瘤量等因素有密切关系。放疗失败的主要原因是局部肿瘤未能控制和肿瘤复发。
From January 1976 to December 1984, 1,110 cases of esophageal cancer were hospitalized with radiotherapy (tumor volume above 40 Gy), including 778 males and 332 females. All patients were irradiated with 60Co in vitro and the tumor volume was 50 Gy to 70 Gy for 5 weeks to 7 weeks. All patients were followed up for more than 5 years. The follow-up rate was 98,3%. The 1-year, 3-year, and 5-year survival rates were 55.9%, 20.1%, and 13.8%, respectively. The effect of radiotherapy is closely related to factors such as patient age, lesion location, lesion length, degree of obstruction, extent of lesion improvement after radiotherapy, and tumor volume. The main reason for the failure of radiotherapy is local tumor failure and tumor recurrence.
