The Value of IOTA Simple Rules Combined With CEUS Scoring System in the Diagnosis of Benign and Malignant Ovarian Masses and Its Correlation With MVD and VEGF: A Preliminary Study.

OBJECTIVES

To investigate the diagnostic value of International Ovarian Tumor Analysis (IOTA) simple rules combined with contrast-enhanced ultrasound (CEUS) scoring system in the differential diagnosis of ovarian tumors, and the correlations of the scoring system with microvessel density (MVD) and vascular endothelial growth factor (VEGF).

METHODS

One hundred eighty-nine patients with ovarian tumors were examined by routine ultrasound and CEUS. The enhanced characteristics of CEUS were observed, and the masses were classified by IOTA simple rules. To compare the diagnostic value of IOTA simple rules combined with CEUS scoring system and IOTA simple rules in the diagnosis of ovarian tumors. Immunohistochemistry was used to detect the expression of MVD and VEGF in postoperative tissue samples. The correlations between the new scoring system with MVD and VEGF were analyzed.

RESULTS

The sensitivity (93.98%), specificity (94.34%), positive predictive value (92.86%), negative predictive value (95.24%), and accuracy (94.18%) of IOTA simple rules combined with CEUS scoring system in the diagnosis of ovarian tumors were higher than those of IOTA simple rules alone (all P < .05). The score system was significantly positively correlated with MVD and VEGF, and the r values were 0.77 and 0.63, respectively (P < .001).

CONCLUSIONS

IOTA simple rules combined with CEUS scoring system was helpful to improve the accuracy of ultrasound diagnosis of ovarian tumors, which was significantly correlated with MVD and VEGF. It could provide important reference information for treatment scheme formulation and prognosis evaluation.
