孤立性肺结节肺癌患病率和相关因素分析

The prevalence of lung cancer with solitary pulmonary nodule and analysis of related factors

目的对影像学孤立性肺结节肺癌患病率和相关因素进行分析,为早期肺癌患者制定诊疗策略提供思路。方法对经手术、穿刺活检和痰检等病理已经确诊的117例孤立性肺结节病例的CT片进行回顾性分析。采用非条件Logistic回归进行相关因素分析。结果肺癌者共计91例,占77.8%,患者年龄、男性、吸烟史、恶性肿瘤病史、毛刺征、分叶征、胸膜凹陷征、血管集束征、空气支气管征、空泡征、多结节征、棘突征与肺癌相关(P<0.05)。结论孤立性肺结节肺癌患病相关因素对良恶性结节的鉴别有意义,应针对影像相关因素,制定进一步的诊疗对策。

Objective To study the prevalence of lung cancer in patients with solitary pulmonary nodule and to analyze the related factors of lung cancer .Methods One hundred and seventeen patients with solitary pulmona-ry nodules have been diagnosed by surgery ,biopsy and sputum pathology .CT scans of the patients were analyzed retrospectively .Related data was analyzed by using Logistic regression analysis .Results The number of lung cancer in these patients was 91 （77.8% ） .The relevant factors of lung cancer were age ,male ,smoking history , history of malignancy ,spiculation ,lobulation ,pleural indentation ,vascular convergence sign ,air bronchogram , vacuole sign ,nodular intrinsic and spinous sign .Conclusion Solitary pulmonary nodule is benign or malignant . Relevant factors of images is related to lung cancer .
