目的探讨肺癌患者空气贮留与肺功能指数的相关性。方法对57例病理确诊为肺癌患者,使用螺旋CT分别进行了不同呼吸时相的连续容积数据模式扫描,对空气贮留进行评分,全部患者作了肺功能检查。结果肺癌患者空气贮留与小气道功能指标FEF25%(r=-0.51,P<0.05),FEF50%(r=-0.77,P<0.01)、RV(r=0.75,P<0.01)高度相关,与FEV1(r=-0.20,P>0.05)、FVC(r=-0.19,P>0.05)、FEV1/FVC(r=-0.35,P>0.05)不相关。结论肺癌患者的空气贮留与小气道功能指标有密切相关性。
Objective To investigate the correlation between air storage and pulmonary function index in patients with lung cancer. Methods Fifty - seven patients diagnosed as lung cancer by pathology were scanned with continuous volume data of different respiratory phases by spiral CT respectively. The air volume was scored and all patients were examined for pulmonary function. Results The air storage in patients with lung cancer was highly correlated with small airway function indexes FEF25% (r = -0.51, P <0.05), FEF50% (r = -0.77, P <0.01) FVC (r = -0.19, P> 0.05) and FEV1 / FVC (r = -0.35, P> 0.05) were not correlated with FEV1 (r = -0.20, P> 0.05) Conclusion The air storage in patients with lung cancer is closely related to the indexes of small airway function.
