多年来人们认识到肺脓肿可合并一定比例的肺癌。文献报告肺脓肿者的肺癌发病率为7.6～17.5%。45岁以上的肺脓肿合并肺癌者多达1/3。因此,许多肺脓肿患者在疾病过程中需行可屈曲式纤维支气管镜检查术(flexible fiberoptic bronchoscopy,FFB)。本文作者回顾性研究了52例肺脓肿行 FFB 的患者,以了解合并肺癌的情况及需行 FFB 的客观标准。本组男49、女3例,据最后诊断把患者分为两组;组Ⅰ 19例(36.5%)为合并肺癌者;组 For many years people have realized that lung abscess can be combined with a certain proportion of lung cancer. The literature reports that the incidence of lung cancer in patients with lung abscess is 7.6 to 17.5%. Lung abscesses over 45 years of age with lung cancer are as much as 1/3. Therefore, many patients with lung abscesses need flexible fiberoptic bronchoscopy (FFB) during disease. The authors retrospectively studied 52 patients with FFB with lung abscess to understand the status of lung cancer and the objective criteria for FFB. This group of 49 males and 3 females, according to the final diagnosis of the patients were divided into two groups; group I 19 patients (36.5%) for lung cancer;
