目的分析CT诊断非小细胞肺癌TNM分期的价值。方法采用回顾性分析方法,以2014年1月-2016年7月,医院采用CT进行TNM分期,并经手术或病理检查诊断的非小细胞肺癌患者115例入组,评价CT的诊断分期价值。结果 CT整体符合率为78.26%,CT对ⅠA期的符合率最高,随着分期的上升,ⅠB~ⅢA期符合率呈下降趋势,ⅢB分期无差异,Kappa一致性检验k=0.82,达到高度一致。CT对淋巴结转移的检验敏感性59.52%(50/84),特异性90.18%(294/326),符合率83.90%(344/410),对侵犯胸膜的敏感性88.37%(38/43)。CT测量病灶大小1.5(0.8~6.5)cm,实际测量水平1.5(0.8~6.8)cm,差异无统计学意义(P>0.05),实测与CT测量病灶的误差(0.4±0.2)cm。结论 CT诊断非小细胞肺癌TNM分期效果较好。
Objective To analyze the value of CT in the diagnosis of TNM staging of non-small cell lung cancer. Methods A retrospective analysis method was used to evaluate the staging value of CT in 115 patients with non-small cell lung cancer diagnosed by surgery or pathology from January 2014 to July 2016 in our hospital. Results The overall coincidence rate of CT was 78.26%. The coincidence rate of CT in stage IA was the highest. With the increase of stage, the coincidence rates of stage IB ~ IIIA showed a decreasing trend, there was no difference in stage IIB, kappa 0.82 with Kappa consistency test . The sensitivity of CT in detecting lymph node metastasis was 59.52% (50/84), specificity was 90.18% (294/326), the coincidence rate was 83.90% (344/410), and the sensitivity of pleural invasion was 88.37% (38/43). The size of lesion was 1.5 (0.8-6.5) cm in CT measurement and 1.5 (0.8-6.8) cm in actual measurement. The difference was not statistically significant (P> 0.05). Conclusion CT diagnosis of non-small cell lung cancer TNM staging better.
