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

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
