目的分析影响孤立性肺结节(solitary pulmonary nodule,SPN)恶性概率的危险因素,对已有的SPN恶性概率预测模型进行验证、比较和改良。方法纳入2017年3~9月在中日友好医院接受诊治、术后获得明确病理诊断的117例SPN患者,其中男59例、女58例,年龄24~83(59.10±11.31)岁。分析影像学上结节最大径、所处部位、毛刺状、分叶征、钙化灶等特点,记录癌胚抗原(CEA)和细胞角蛋白19片段抗原(Cyfra21-1)等血清学检验结果,应用单因素分析模型分析临床资料与术后病理良恶性诊断的关系,应用不同SPN恶性概率预测模型绘制受试者工作特征曲线(receiver operating characteristic curve,ROC曲线),得到各模型的曲线下面积(area under curve,AUC)、灵敏度、特异度、阳性预测值、阴性预测值等并进行比较,探索模型改进方法。结果 117例患者中经病理诊断为恶性肿瘤93例(79.5%),良性肿物24例(20.5%),单因素分析发现患者年龄、结节最大径、血清CEA和Cyfra21-1水平、毛刺状、分叶征及钙化表现在良、恶性SPN之间的差...
【英文摘要】
Objective To identify risk factors that affect the verification of malignancy in patients with solitary pulmonary nodule(SPN) and verify different prediction models for malignant probability of SPN. Methods We retrospectively analyzed the clinical data of 117 SPN patients with definite postoperative pathological diagnosis who underwent surgical procedure in China-Japan Friendship Hospital from March to September 2017. There were 59 males and 58 females aged 59.10±11.31 years ranging from 24 to 83 years. Ima...
