Objective To evaluate significance of barium esophagography combined with CT in the evaluation of short-term efficacy of radiotherapy for esophageal cancer. Methods A total of 62 patients with esophageal cancer on radiotherapy at Baoji Central Hospital were selected from January 2012 to December2012. According to the different efficacy evaluation methods,patients were divided into the contrast group and the combination group,with 31 patients in each group. The contrast group received esophagogram evaluation method,and the combination group used esophageal barium meal combined with CT comprehensive evaluation method. Clinical efficacy and tumor metastasis rate were compared between the two groups.Results The 1-,3-and 5-year efficacy rate was 74. 2%,48. 4% and 35. 5% for the contrast group and83. 9%,61. 3% and 45. 2% for the combination group with the combination group higher than the contrast group( all P 0. 05). The 1-,3-and 5-year tumor metastasis rate was 35. 5%,58. 1% and 74. 2% in the contrast group and 16. 1%,38. 7% and 48. 4%,respectively for the combination group with,the latter lower than the former( all P 0. 05). Conclusion Barium esophagography combined with CT has a high accuracy in evaluating the short-term efficacy of radiotherapy for esophageal cancer. It is helpful for guiding the subsequent treatment,and is worthy of popularization and application.
