胸外科住院肺癌合并慢性阻塞性肺疾病的调查结果分析

背景与目的 肺癌是慢性阻塞性肺疾病(慢阻肺)重要的合并症,会显著影响慢阻肺患者的预后.慢阻肺也会影响肺癌患者的术后并发症和复发.本研究旨在调查胸外科住院肺癌合并慢阻肺的情况.方法回顾性分析北京大学人民医院胸外科2015年1月-2015年12月收治的原发性非小细胞肺癌患者.通过查阅病历获取患者的性别、年龄、吸烟状况、有害职业史、症状、胸部计算机断层扫描(computed tomography,CT)、术后病理、出院诊断、全套肺功能及支气管舒张试验,当基础肺功能第一秒钟用力呼气容积(forced expiratory volume in one second,FEV1)占预计值<70%时即行支气管舒张试验.结果703例肺癌患者进行了全套肺功能测定,其中67例进行支气管舒张试验,62例(92.5%)符合慢阻肺诊断.接受手术治疗的肺癌患者有677例,其中41例进行支气管舒张试验,38例(92.7%)符合慢阻肺诊断.在接受手术治疗的肺癌患者中合并慢阻肺者年龄≥65岁、男性、有吸烟史和非腺癌的比例高于未合并慢阻肺者,差异有统计学意义(P<0.05);男性和≥65岁者更易合并慢阻肺(OR:2.807-2.374,95%CI:1.101-7.157)(P<0.05).住院前仅有3例(4.3‰)诊断慢阻肺并按慢阻肺规范治疗.出院时仅有5例(7.1‰)诊断慢阻肺.结论在胸外科住院肺癌患者中行常规肺功能及支气管舒张试验可提高肺癌合并慢阻肺的诊断;当前肺癌合并慢阻肺诊断和治疗严重不足,需要引起胸外科医生重视,与呼吸内科医生携手共同防治慢阻肺.

Investigation of Lung Cancer Patients Complicated with Chronic Obstructive Pulmonary Disease in Thoracic Surgical Department

Background and objective Lung cancer is an important complication of chronic obstructive pulmo-nary 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) scan-ning, 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.Conclusion 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.
