BACKGROUND: Lung cancer is an important complication of chronic obstructive pulmonary disease (COPD), and even significantly affects the prognosis of patients with COPD. COPD also affects the postoperative complications and recurrence in patients with lung cancer. This study aims to investigate lung cancer patients complicated with COPD in thoracic surgical department. METHODS: All medical records of lung cancer patients discharged from the Department of Thoracic Surgery of People's Hospital, Peking University during January 2015 and December 2015 were reviewed, including gender, age, tobacco smoke history, harmful occupational exposure, clinic symptom, chest computed tomography (CT) scanning, postoperative pathology result report, discharged diagnosis and spirometry [All patients underwent pulmonary function test are received bronchial dilation test if the based predicted value of forced expiratory volume in one second (FEV1) <70%]. RESULTS: A full set of lung function test was measured in 703 lung cancer patients. Bronchial dilation test was finished in 67 patients. 62 (92.5%) patients were diagnosed as COPD. 677 cases with lung cancer were received surgery. Bronchial dilation test was measured in 42 cases. Of them 38 (92.7%) patients were diagnosed as COPD. It was found that the patients with lung cancer and COPD was more frequent in males, elders (≥65 yr), smokers, non-adenocarcinoma patients than those of patients without COPD (P<0.05). The males and the elders (≥65 yr) were more likely to suffer from COPD (OR: 2.374-2.807, 95%CI: 1.101-7.157)(P<0.05). Only 3 patients (4.3‰) were diagnosed as COPD and received standard treatment before admission. And only 5 patients (7.1‰) were diagnosed as COPD as discharged. CONCLUSIONS: The routine pulmonary function as well as bronchial dilation test are helpful for screening the patients with COPD. At present, the diagnosis and treatment of lung cancer combined with COPD is a serious problem, which needs to be paid attention to by thoracic surgeons and to join hands with physicians in order to improve the diagnosis level of COPD.

用Epidata 3.0软件进行数据录入,双人录入并进行一致性检验后,导入SPSS 19.0(SPSS Inc., Chicago, IL, USA)软件进行数据统计分析。其中计量资料采用Mean±SD表示,计数资料用例数(构成比)表示。利用t和χ2检验比较手术治疗肺癌合并/未合并慢阻肺患者的临床特征差异,将性别、年龄、吸烟纳入多因素Logistic回归,分析肺癌合并慢阻肺的影响因素。P<0.05为差异具有统计学意义。
结果
胸外科住院肺癌患者合并慢阻肺的情况
全年共有703例肺癌患者进行了全套肺功能测定,其中19例患者吸入支气管舒张剂前FEV1/FVC<70%,因其FEV1占预计值%≥70%,未做支气管舒张试验。进一步分析这些患者的肺功能测定结果和临床资料,其中有4例残气和/或肺总量占预计值%>120%;有5例弥散功能(diffusing capacity of the lung for carbon monoxide, DLCO)占预计值%<80%;两者均异常的有4例。有17例胸部高分辨率CT显示有不同程度肺气肿征象。67例行支气管舒张试验的患者中有62例(92.5%)符合慢阻肺诊断,按气流受限严重程度的肺功能分级,Ⅰ级5例,Ⅱ级46例,Ⅲ级8例,Ⅳ级3例。合并慢阻肺的肺癌中鳞癌38例,腺癌22例,大细胞癌1例,支气管粘液表皮样癌1例。
