目的探讨16层螺旋CT(16-SCT)在诊断非小细胞肺癌TNM分期与病理TNM分期的相关一致性。方法选用由16-SCT检查并经手术治疗的84例非小细胞肺癌病例,采用国际肺癌TNM分期(1997年)标准进行诊断,将16-SCT诊断的TNM分期结果与手术、病理分期结果进行比较,分析16-SCT诊断分期结果与手术病理TNM分期相关一致性。结果16-SCT诊断肺癌的TNM分期与病理分期有良好的一致性。在总的TNM分期中,16-SCT的符合率、灵敏度、特异度分别达到91.7%、82.2%、93.7%。16-SCT在诊断非小细胞肺癌T、N分期中,与病理的Kappa值分别为0.84、0.79。结论16-SCT能够准确诊断非小细胞肺癌TNM分期,16-SCT为非小细胞肺癌的诊断治疗提供重要的影像学资料。
Objective To investigate the correlation between 16-slice spiral CT (16-SCT) and TNM staging in non-small cell lung cancer (NSCLC). Methods Eighty-four non-small cell lung cancer cases were examined by 16-SCT and surgically treated. TNM staging (1997) was used to diagnose lung cancer. The TNM staging results by 16-SCT were compared with those by surgery and pathological staging , Analysis of 16-SCT diagnostic staging and surgical pathology related TNM staging consistency. Results 16-SCT diagnosis of lung cancer TNM staging and pathological staging have a good consistency. In the total TNM staging, the coincidence rate, sensitivity and specificity of 16-SCT reached 91.7%, 82.2% and 93.7% respectively. 16-SCT in the diagnosis of non-small cell lung cancer T, N stage, and pathological Kappa values were 0.84,0.79. Conclusion 16-SCT can accurately diagnose non-small cell lung cancer TNM staging. 16-SCT provides important imaging data for the diagnosis and treatment of non-small cell lung cancer.
