目的 :为了准确地预测食管癌术前淋巴结转移情况 ,并对食管癌术前CT分期及术后TNM分期对比。方法 :6 0例经病理学证实的食管癌病人行术前CT检查 (平扫加增强扫描 5 6例 ) ,并与手术及术后病理结果相对比。结果 :术前CT检查对淋巴结转移的敏感性、特异性及准确性分别为 48.0 0 %、81.48%及 6 5 .38%。按术前CT的Moss法分期 :Ⅰ期 ,0 ;Ⅱ期 39;Ⅲ期 18;Ⅳ期3。与术后的国际TNM分期符合 49例 ,符合率为 81.6 7%。结论 :食管癌术前CT检查对淋巴结转移的预测是较有价值和重要的 ,还可协助制定治疗方案等。目的 :为了准确地预测食管癌术前淋巴结转移情况 ,并对食管癌术前CT分期及术后TNM分期对比。方法 :6 0例经病理学证实的食管癌病人行术前CT检查 (平扫加增强扫描 5 6例 ) ,并与手术及术后病理结果相对比。结果 :术前CT检查对淋巴结转移的敏感性、特异性及准确性分别为 48.0 0 %、81.48%及 6 5 .38%。按术前CT的Moss法分期 :Ⅰ期 ,0 ;Ⅱ期 39;Ⅲ期 18;Ⅳ期3。与术后的国际TNM分期符合 49例 ,符合率为 81.6 7%。结论 :食管癌术前CT检查对淋巴结转移的预测是较有价值和重要的 ,还可协助制定治疗方案等。 Objective: To accurately predict the preoperative lymph node metastasis of esophageal carcinoma, and to compare the preoperative CT staging and postoperative TNM staging of esophageal carcinoma. Methods : Sixty patients with esophageal cancer confirmed by pathology underwent preoperative CT examination (56 plain scan plus enhanced scan). The results were compared with the results of surgery and postoperative pathology. Results: The sensitivity, specificity and accuracy of preoperative CT examination for lymph node metastasis were 48.00%, 81.48% and 65.8%, respectively. According to the Moss method of preoperative CT, staging: stage I, 0; stage II 39; stage III 18; stage IV 3. The international TNM stage was consistent with postoperative 49 cases, with a compliance rate of 81.67%. Conclusion: Preoperative CT examination of esophageal cancer is valuable and important in predicting lymph node metastasis. It can also assist in the development of treatment protocols.
