摘　　要：目的探讨彩色多普勒超声在睾丸精原细胞瘤与淋巴瘤鉴别诊断中的价值。方法选取我院经手术病理证实的睾丸肿瘤患者80例,其中睾丸精原细胞瘤50例,睾丸淋巴瘤30例,均为单发病灶。比较二者超声特征;建立Logistic回归模型,绘制受试者工作特征(ROC)曲线分析Logistic回归模型的诊断效能。结果睾丸精原细胞瘤与睾丸淋巴瘤形态、边界、内部回声、无回声区、后方回声比较差异均有统计学意义(均P<0.05)。建立的回归方程为:Logistic(Y)=0.282+1.451X1+2.745X2-0.719X3-1.857X4-2.376X5(X1:形态,X2:边界,X3:内部回声,X4:无回声区,X5:后方回声)。ROC曲线分析显示,Logistic回归模型鉴别睾丸精原细胞瘤与睾丸淋巴瘤的敏感性为96.7%,特异性为83.0%,准确率为70.1%,曲线下面积为0.884。结论彩色多普勒超声在鉴别睾丸精原细胞瘤与睾丸淋巴瘤中具有较高的临床应用价值。ABSRTACT Objective To explore the value of color Doppler ultrasound in the differential diagnosis of testicular seminoma and lymphoma.Methods A total of 80 cases of single lesions of testicular tumor were selected,including 50 cases of testicular seminoma and 30 cases of testicular lymphoma,all cases were confirmed by operation and pathology.The paramerers among groups were compared.The diagnositic model was established and Logistic regression analysis was conducted.Results Between testicular seminoma and lymphoma,there were statistical significance in the shape,boundary,internal echo,non echo area and rear echo(all P<0.05).Logistic(Y)=0.282+1.451 X1+2.745 X2-0.719 X3-1.857 X4-2.376 X5(X1:shape,X2:boundary,X3:internal echo,X4:non echo area,X5:rear echo).ROC curve showed that the sensitivity,specificity and accuracy of the model in the differential diagnosis of testicular seminoma and lymphoma were 96.7%,83.0%and 70.1%,respectively.The area under ROC curve was 0.884.Conclusion Color Doppler ultrasound has high clinical value in the differential diagnosis of testicular seminoma and testicular lymphoma.
