【摘要】 分析资料完整、无表浅淋巴结及远处转移、首程放疗的食管癌患者 34 83例 ,均随访 1 0年以上。病人采用60 Co常规外照射 ,剂量均在 5 0Gy以上。若将食管病变部位及病变长度相结合 ,再进行分析对比 ,其结果是食管胸下段癌的生存率与其它各段之间无明显差别。过去认为食管下段癌预后差 ,其原因可能是在分析部位时未将病变长度结合在一起。食管胸下段癌单纯放疗的预后并不是最差的。更多还原

【Abstract】 From October 1969 through December 1981, 3483 esoghageal carcinomas without superficial lymphatic metastasis were treated by 60 Co in our hospital. The radiation dose was over 50Gy and follow-up was over ten years. Results: No significant difference of survival rates was found in various cancer locations in the esophagus combined with the data between our hospital and Xingtai Tumor Hospital, the 5-year survival rates for lower third esophageal cancer were 20.7%～36.4% in surgery group and only 4.3% in radiation group. The 5-year survival rates were also significantly diffrent between radiation group(34.7%) and surgery group (64.9%) for cancer length of <5cm. We consider that the prognosis of lower third thoracic as reported in the past is due to the fact that most lower third thoracic esophageal cancers were treated with longer courses.更多还原
