RADIATION PROGNOSIS OF LOWER THIRD THORACIC ESOPHAGEAL CARCINOMA / 中华放射肿瘤学杂志

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
