Abstract
OBJECTIVES: To evaluate shear wave elastography (SWE) technology diagnosis value of endometrial cancer (EC) and atypical endometrial hyperplasia (AEH), and to establish predictive logistic regression models for the diagnosis of EC and AEH. METHODS: Clinical information collection, transvaginal conventional ultrasonography, and SWE check were performed on 122 patients, who were perimenopausal or postmenopausal vaginal bleeding with ≥4.5 mm thick endometrium. The maximal (Emax) and mean (Emean) of Young's modulus for the endometrium were obtained. Using pathology as the gold standard, ROC curves were plotted to evaluate Young's modulus on the diagnostic effectiveness of EC and AEH. Single-factor analysis and bivariate logistic regression methods were applied to assess the clinical variables, transuaginal conventional ultrasonography variables, and Young's modulus on the identification of EC and AEH. RESULTS: Out of 122 cases of endometrial lesions, 85 cases were benign lesions, and the remaining 37 cases were EC and AEH. The Emax and Emean for the benign group were 29.80 ± 11.40 and 17.96 ± 8.05 kPa, respectively. The Emax and Emean values for EC and AEH group were 59.49 ± 16.95 and 38.46 ± 17.10 kPa, respectively. Emax and Emean for both groups were statistically significant, with p <.001. In the logistical regression analysis, endometrial thickness, Color score, and Young's modulus were identified as independent risk factors for EC and AEH. CONCLUSIONS: SWE technology plays an important role in the diagnosis of EC and AEH, and the diagnostic effectiveness would be higher when combined with conventional ultrasonography.
