目的探讨胸段食管癌临床TNM分期与手术病理结果的一致性。材料和方法对1992年12月至1997年12月86例具有完整术前临床资料的胸段食管瘤病人，根据UICC的TNM分期系统，进行术前临床“T”、“N”、“TNM”分期，术后根据手术病理结果采用Kappa统计量进行一致性分析。结果临床“T”分期与手术病理结果具有较好的一致性（Kappa＝0．6736）．临床“N”和CTNM分期与手术病理结果的一致性较差，Kappa值分别为0．0822和0．3668。结论目前的临床诊断技术能较好地反应食管癌原发灶的侵犯程度，但诊断淋巴结转移尚存在严重不足；寻找更有效的淋巴结转移诊断技术是提高食管癌CTNM分期准确性的关键。
Objective To investigate the clinical TNM staging of thoracic esophageal carcinoma and the consistency of surgical pathology. Materials and Methods For patients with thoracic esophageal tumors with complete preoperative data from December 1992 to December 1997, preoperative clinical “T”, “N”, and “TNM” were performed according to UICC’s TNM staging system. Staging, postoperative follow-up pathological results using Kappa statistics for consistency analysis. Results The clinical “T” staging had a good agreement with the surgical pathological results (Kappa = 0.6736). The consistency between clinical “N” and CTNM staging and surgical pathology results was poor, with Kappa values of 0.0822 and 0.3668, respectively. Conclusion Current clinical diagnostic techniques can better reflect the extent of primary lesions of esophageal cancer, but there are still serious deficiencies in the diagnosis of lymph node metastasis. Finding more effective diagnostic techniques for lymph node metastasis is the key to improving the accuracy of CTNM staging of esophageal cancer.
