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。
Objective: To investigate the value of CT in preoperative staging of bronchogenic carcinoma. Methods: Sixty-three patients with bronchogenic carcinoma (non-small cell type) confirmed by surgery and pathology were analyzed by CT-pathology. Results: The coincidence rate of CT staging and postoperative pathology was 72%, 62%, 77% in stage A, 80% in stage B, 100% in period, and the overall coincidence rate was 75%. Sensitivity of CT in diagnosing lymph node metastasis was 63%, specificity was 60%, and accuracy rate was 62%. Conclusion: CT is more accurate in detecting the primary tumor (T) and distant metastasis (M) in lung cancer and has a certain limit to lymph node metastasis (N).
