  • Title: Transvaginal color Doppler and CA125 as tools in the differential diagnosis of postmenopausal ovarian masses.

    Journal: Maturitas; 1997 Apr; 26(3):203-9. PubMed ID: 9147352.
    Abstract:
    OBJECTIVE: To evaluate whether transvaginal color Doppler and CA125 are valid in differentiating malignant from benign postmenopausal ovarian masses. METHODS: Sixty-two women with ovarian masses were studied with transvaginal color Doppler ultrasound before surgery. Serum CA125 levels were also measured. Resistance index (RI) and pulsatility index (PI) were calculated from the waveforms generated from blood flow within the ovary. RESULTS: Benign tumors had a significantly higher pulsatility index (mean 1.23 +/- 1.02; range 0.65-2.99) and resistive index (mean 0.78 +/- 0.22; range 0.5-1.1) than did malignant tumors. However some overlap in individual values for benign and malignant lesions was found. RI and PI sensitivity were significantly higher than those with CA125 (P < 0.05). Blood flow was detectable by color Doppler imaging in 95% of cases with malignant masses. CONCLUSION: Doppler sonographic evaluation of resistance and pulsatility indexes in the vessels of ovarian masses together with CA125 increased the sensitivity of prediction of malignancy for pelvic masses, but further work is needed before the validity of these factors is proved.
