Doppler flowmetry in the differentiation of biological characteristics of ovarian cancer.

On basis of ultrasonographic structural criteria and Doppler flowmetry in a group of 76 patients with ovarian cancer, benign lesions were discovered in 59 patients and malignant lesions in 17 patients (77.6% and 22.4%, respectively). Surgical intervention was indicated according to the clinical findings and following of the trend of organ-specific oncomarkers in 32 out of 76 patients (42.1%). The stratification involved 17 patients with sonomorphologically/Doppler-flowmetry - diagnosed malignancy as well as 15 patients with sonographically diagnosed benign ovarian tumor. The clinical findings were histologically verified in all 32 patients. Histology confirmed malignant tumor in 16 patients, 1 histologically borderline malignancy and 15 benign tumors. The Doppler-flowmetry showed 94.1% sensitivity, 93.3% specificity, 93.3% positive predictive value, and 93.75% accuracy.
