| 目的 探讨彩色多普勒超声在睾丸精原细胞瘤和淋巴瘤鉴别诊断中的价值。
方法 选取睾丸肿瘤手术患者共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。运用?2检验比较两组组间的特点，用自变量X来表示有统计学意义的参数，因变量 Y来表示病理结果，按彩色多普勒超声设立模型并行Logistic回归分析。
结果 声像图特点中形态、边界、内部回声、无回声区、后方回声有统计学意义（P均<0.05)。回归模型具有统计学意义（P <0.05)。模型的灵敏度96.7%,特异度83%,准确率 70.1%。Logistic 回归模型的 ROC 曲线下面积为0.884。
结论 彩色多普勒超声对睾丸精原细胞瘤与睾丸淋巴瘤的鉴别诊断中具有较高临床应用价值。 |

| Abstract: |
| Absrtact:Objective To explore the value of color Doppler ultrasound in the differential diagnosis of testicular seminoma and lymphoma. Methods 80 cases of testicular tumor were selected, including 50 cases of testicular seminoma and 30 cases of testicular lymphoma. The paramerers among groups were compared by ?2 test. The diagnositic model was established and Logistic regression analysis was conducted. Results There were statistical significance in the shape, boundary, internal echo, non echo area and rear echo (all P < 0.05). The regression model was statistically significant (P < 0.05). The sensitivity, specificity and accuracy of the model were 96.7%, 83% and 70.1%, respectively. The area under ROC curve of logistic regression model is 0.884. Conclusions Color Doppler ultrasound has high clinical value in the differential diagnosis of testicular seminoma and testicular lymphoma. |
