【摘要】 目的 :探讨 CT对支气管肺癌术前分期的价值。方法 :经手术和病理证实的支气管肺癌 (非小细胞型 )共 6 3例 ,对其 CT-病理对照分析。结果 :CT分期和术后病理符合率为 期 72 % , 期 6 2 % , A期 77% , B期 80 % , 期 10 0 % ,总体符合率 75 %。CT诊断淋巴结转移的敏感性 6 3% ,特异性 6 0 % ,准确率 6 2 %。结论 :CT对显示肺癌原发灶 (T)和远处转移 (M)较准确 ,对淋巴结转移 (N)有一定限度。更多还原

【Abstract】 Objective:To explore the value of CT staging of bronchogenic carcinoma.Methods:The CT-pathologic correlative analysis of bronchegenic carcinoma(NSBC)confirmed by operation and pathologic histology was performed in 63 patients.Results:The results showed that the correspondent rates of CT-pathology were 72% in stage Ⅰ,62% in stage Ⅱ,77% in stage Ⅲ A,80% in stage Ⅲ B and 100% in stage Ⅳ.The overall rate of correspodance was 75%.In detecting metastatic lymph nodes by CT the sensitivity was 63%,the specificity was 60% and the diagnostic accuracy rate was 60%.Conclusion:CT is an effective method in diagnosis of tumor(T) and distant metastasis(M),but CT scan is limited in detecting the metastatic lymph nodes.
