Application value of color Doppler ultrasound in the differential diagnosis of testicular seminoma and testicular lymphoma

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.
