212例孤立肺结节的临床分析

目的：对直径≤30mm孤立肺结节进行临床分析。方法：回顾性分析2007年1月-2008年3月我院212例孤立肺结节患者的临床资料,比较良、恶性结节的临床差异。结果：本组男女比例为1.5：1,临床表现无特异性,一半以上因查体发现。螺旋CT为术前常见检查途径。212例患者均行手术治疗,149例（70.3%）病理诊断为恶性。结论：孤立肺结节恶性所占比例较高,应早发现、早治疗,鉴别诊断困难时应积极手术。

Clinical analysis of 212 cases of solitary pulmonary nodules

Objective： To analyze the clinical solitary pulmonary nodules （SPN） less than 30mm in diameter. Methods： Clinical data of 212 patients with SPN admitted to our hospital from January 2007 to March 2008 were reviewed. Clinical differences in benign and malignant SPN were compared. Results ： The male and female ratio was 1.5： 1.0. No specificity was observed in clinical manifestations of SPN and over 50% of clinical manifestations of SPN were discovered at routine examinations. Computed tomography was used to detect the lesions before operation. All patients underwent surgical resection of SPN and malignant SPN were found in 149 cases （70.3%）. Conclusion： Malignant SPN were much more common than benign SPN. SPN should be detected at their early stage and surgically removed.
