Abstract
ObjectiveTo explore the factors affecting the prognosis of precise radiotherapy of esophageal carcinoma after surgery, provide the measures to improve the life quality of the patients.Method633 cases of patients with thoracic esophageal carcinoma after radical operation and postoperative radiotherapy in our hospital from June 2007 to April 2009 were grouped and compared in accordance with the 1, 3, 5 year survival situation, a single factor analysis of clinical patients in each group, and sums up the factors affecting prognosis by Logistic multi factor regression analysis.Result633 patients were followed up for 1 year, the survival of 574 cases (90.7%), 3 year survival of 375 cases (59.2%), 5 year survival of 289 cases (45.7%), the mean survival time was (46.9±8.2) months; single factor regression analysis showed that, the survival of patients, tumor size, lymph node transfer number, TNM staging were signiifcant statistically (P<0.05); multi factor regression analysis showed that, the tumor diameter≥3 cm, lymph node metastasis and TNM stageⅢ/Ⅳ≥3 period were the results of independent risk factors of poor prognosis in precise radiotherapy of thoracic esophageal carcinoma after operation (P<0.05).ConclusionThoracic esophageal carcinoma after radiotherapy in improving the accuracy of long-term survival in patients with signiifcant, and in patients with risk factors have a poor prognosis, in clinical treatment in the future, as appropriate, to increase the patient's lymph node dissection and radiotherapy range, in order to reduce the metastasis of cancer cells, improve the quality of life.关键词
