目的 分析CT检查对中晚期食管癌分期的意义。材料与方法 搜集我院作CT扫描并经手术或放疗的中晚期食管癌患者 5 3例 ,研究其CT征象和手术病理所见 ,分析病变对邻近脏器侵犯的特征 ,以及转移淋巴结的显示情况。根据 1976年我国制定的食管癌临床分期标准 ,结合CT和手术结果分期 ,5 3例中 ,Ⅱ期 13例 ,Ⅲ期 31例 ,Ⅳ期 9例。结果 CT能精确显示食管壁的增厚程度 ,对邻近脏器侵犯的估计与手术对照正确率达 85 %以上 ,对局部和远处淋巴结显示的敏感性低于 70 % ,对远处脏器的转移只要扫描范围充分 ,均能明确诊断。结论 术前CT检查对食管癌分期、手术可切除性、放疗的重点和范围 ,以及预后的估价有重要意义。
Objective To analyze the significance of CT examination in the staging of advanced esophageal cancer. Materials and Methods Fifty-three patients with advanced esophageal carcinoma who underwent CT scan and undergone surgery or radiotherapy were collected to study their CT signs and surgical pathology findings. The characteristics of lesions on adjacent organs were analyzed, and the status of lymph node metastases was also analyzed. . According to the clinical staging criteria for esophageal cancer established in China in 1976, combined with CT and staging of surgical outcomes, 53 cases, 13 cases in stage II, 31 cases in stage III, and 9 cases in stage IV. Results The CT can accurately show the thickening of the esophagus wall. The accuracy of the assessment of the invasion of adjacent organs was higher than 85% with the surgical control, and the sensitivity of the local and distant lymph nodes was less than 70%. The transfer can be clearly diagnosed as long as the scan scope is adequate. Conclusion Preoperative CT examination is of great significance for staging of esophageal cancer, resectable surgery, emphasis and scope of radiotherapy, and evaluation of prognosis.
