Estimation of neovascularisation in hyperplasia and carcinoma of endometrium using a "power" angio-Doppler technique

The aim of this study was to estimate neovascularisation in hyperplasia and carcinoma of the endometrium using a "power" angio-Doppler technique. One hundred and eighty-two postmenopausal patients with irregular bleeding from the sexual organs were investigated. Age of the patients ranged between 46 and 78 years. No neovascularisation in a control group of women with normal histopathological results of the endometrium was observed. The sensitivity of this method with reference to the diagnosis of hyperplasia and cancer of the endometrium was 12.2% and 81.2%, respectively. The specificity and positive prediction values were equal to 100% each in both pathologies. The values of the analysed flow indices in the neovascular arteries in endometrial cancer were significantly lower (p<0.05) (properly PI-0.92+/-0.12; RI-0.46+/-0.08) in comparison to the corresponding values in hyperplasia of the endometrium (PI-1.38+/-0.28 and RI-0.66+/-0.18). In conclusion, using a "power" angio-Doppler technique irregular vascularity of the endometrium in a group of patients with hyperplasia was observed in 12.2% of all patients and in 81.2% of those with cancer of the endometrium. The analysis of the values of the blood flow qualitative parameters in the neovascularisation areas in the endometrium at the significance level of PI < or = 1.0; RI < or = 0.5 and TAMV > 18.0 cm can help determine the essential element in the differential diagnosis of benign and malicious lesions. Transvaginal ultrasonography with a "power" angio-Doppler technique can be a valuable diagnostic method in hyperplasia and cancer of the endometrium, especially useful in the early stages of these pathologies.
