慢性阻塞性肺疾病与肺癌的临床关系分析

目的探讨COPD与肺癌的临床关系,以便早期诊断及降低肺癌发生率。方法分析临床68例COPD合并肺癌及30例单纯COPD患者及30例正常对照组病例的临床特点。结果在所有的危险因素中,长期吸烟暴露率最高。COPD合并肺癌、单纯COPD以及正常对照组3组之间肺功能差异有统计学意义（P〈0．05）。结论吸烟是COPD和肺癌患者的主要危险因素：动态监测COPD患者的肺功能特别是弥散功能有利于早期发现肺癌。

Clinical relation analysis of chronic obstructive pulmonary disease and lung cancer

Objective To investigate the clinical relation of COPD and lung cancer to diagnosis early and reduce the incidence. Methods Analyzed the clinical characteristics of 68 patients with COPD combined lung cancer and 30 cases of simple COPD patients and 30 cases of normal control patients. Results Long-term smoking was the highest rate in all risk factors. COPD combined lung cancer, simple COPD and normal control group, lung function of the three groups has differences, and have statistical significance （P 〈 0.05）. Conclusion Smoking is the main risk factor for COPD and lung cancer; Dynamically monitoring lung function of COPD patients is helpful for the early detection of lung cancer.
