Correlation between Blood Flow Parameters of Four-dimensional Power Doppler Ultrasound and Disease Stage in Patients with Cervical Cancer
Objective:To explore the correlation between the blood flow parameters of four-dimensional power Doppler ultrasound and the disease stage in patients with cervical cancer.Methods:80 patients with cervical cancer who were treated in our hospital from August 2019 to July 2022 were selected as the study group,another 50 patients with cervical intraepithelial neoplasia who were admitted to the hospital during the same period were selected as the CIN group,and 50 patients with benign lesions of the uterus at the same period were selected as the control group.Four-dimensional power Doppler ultrasound was performed on them respectively to compare the differences of ultrasound parameters between the three groups,The patients in the study group were divided into different disease stages(stage Ⅰ 23,stage Ⅱ 34,stage Ⅲ 23)according to the FIGO standard,and the differences of ultrasound parameters in different stages of cervical cancer were compared,and the differential value of ultrasound parameters in different stages of cervical cancer was evaluated by drawing the subject curve(ROC).Results:There were significant differences in ultrasound blood flow parameters PSV and RI between the study group,CIN group and the control group,and the difference between the two groups was statistically significant(P＜0.05);There were significant differences in ultrasound blood flow parameters among patients with different stages of cervical cancer.PSV of FIGO Ⅲ was the highest and RI was the lowest.The same difference was statistically significant between the two groups(P＜0.05);The AUC of PSV was 0.6829(95％CI=0.5333-0.8324,P=0.0200)for FIGO Ⅰ to FIGO Ⅱ,0.7698(95％CI=0.6402-0.8995,P=0.0006)for FIGO Ⅱ to FIGO Ⅲ,and 0.7505(95％CI=0.6072-0.8937,P=0.0036)for FIGO Ⅰ to FIGO Ⅲ;The AUC of RI was 0.9309(95％CI=0.8662-0.9957,P＜0.001)for FIGO Ⅰ to FIGO Ⅱ,0.7148(95％CI=0.5804-0.8493,P=0.0063)for FIGO Ⅱ to FIGO Ⅲ,and 0.9811(95％CI=0.9504-1.000,P＜0.001)for FIGO Ⅰ to FIGO Ⅲ.Conclusion:The blood flow parameters of four-dimensional power Doppler ultrasound in patients with cervical cancer have a certain correlation with their disease stages.The application of PSV and RI index in the differentiation of cervical cancer stages has good application value and has the significance of popularization and application.
