[Evaluation of predictive value of the ultrasound Doppler's scale in determination of the ovarian tumors malignancy].
Ultrasound examination with the use of the transvaginal probe is extremely important among early detection methods of the ovarian tumors. Application of the Doppler's technique makes it possible to evaluate vascularity of the tumors in the light of malignancy prognosis.


OBJECTIVE
Evaluation of predictive value of the suggested Doppler's Scale (DS.) detecting preoperative degree of the ovarian tumor malignancy.


METHODS
The analyses involved data obtained in evaluation of 464 ovarian tumors of women treated in Gynecology and Obstetric Clinical Hospital of the Karol Marcinkowski University of Medical Sciences, Poznan, Poland in the years 1994-2002. As a result of histopathological examination, 165 patients had a malignant ovarian tumor detected, and other 299 were found to suffer from a benign tumor. Predictive values among the scrutinized group of women were also analyzed in respect of their menopausal status by determining appropriate values for women before and after menopause. The obtained data allowed to draw ROC curves and to compare diagnostic value of the suggested scale for the groups of patients under the scrutiny. Evaluation involved: number of vessels, their location and arrangement, shape of velocity waves as well as presence of the protodiastolic notch in the arterial vessels of the tumor. Each of the mentioned features could acquire a point-value of 0 or 1.


RESULTS
A cut-off point for the suggested Doppler's evaluation scale of the ovarian tumors vascularity was determined at the level of 4. The following predictive values were obtained: [table: see text]


CONCLUSIONS
Tumor features analyses as a result of ultrasound Doppler's evaluation enables precise prognosis of the malignancy degree. The suggested point-scale concerning the most significant elements of the Doppler's half-amount analyses facilitates precise determination of the malignancy degree of the ovarian tumors and enables selection of the most effective of therapeutic treatment. The technique is a precious supportive tool in the preoperative detection of the ovarian tumors malignancy.
