Value of ADNEX model combined with three-dimensional power Doppler ultrasound in distinguishing benign and malignant ovarian tumors
Objective To explore and evaluate the clinical application value of different ADNEX(assessment of different neoplasias in the adnexa)model combined with 3D power Doppler ultrasound(3D-PDUS)in distinguishing benign from malignant ovarian tumors.Methods From October 2022 to June 2023,67 tumors of 64 patients with ovarian tumors who underwent surgical treatment in Meizhou People's Hospital and underwent two-dimensional and three-dimensional ultrasound examination before operation were collected retrospectively.According to pathological classification,they were divided into benign group(40)and malignant group(27),and ADNEX model analysis was performed separately.The differences in 3D-PDUS blood flow parameters between benign and malignant ovarian tumor groups were compared,meaningful indicators were screened,and the diagnostic results of the ADNEX model were upgraded or downgraded based on this accordingly.The ROC curves of ADNEX model and 3D-PDUS in the diagnosis of ovarian tumors were drawn respectively,and the values of ADNEX model and 3D-PDUS in the diagnosis of benign and malignant ovarian tumors were compared.Results The vascularity index(VI)and vascularization-flow index(VFI)of 3D-PDUS in the malignant group were higher than those in the benign group,and the differences were statistically significant(P＜0.05).After adjusting the grading of ovarian tumors based on VI and VFI values,among the ovarian tumors with the pathological nature of benign,8 were correctly downgraded to benign and 2 were incorrectly upgraded to malignant,and 2 of the ovarian tumors with a malignant pathological nature were incorrectly downgraded to benign and one was correctly upgraded to malignant.The AUC value of the ADNEX model was 0.751(95％CI:0.631-0.871),with a sensitivity of 85.2％,a specificity of 65.0％,a positive predictive value of 62.2％,and a negative predictive value of 86.7％.After joining forces with 3D-PDUS,the AUC value was 0.826(95％CI:0.719-0.932),with a sensitivity of 85.2％,a specificity of 80.0％,a positive predictive value of 74.2％,and a negative predictive value of 88.9％,and all diagnostic indexes except sensitivity were improved.Conclusion The ADNEX model combined with 3D-PDUS technology can better distinguish benign from malignant ovarian tumors,and improve the diagnostic specificity without reducing the sensitivity.
