ABSTRACT

Purpose: The comparison of the two risks of malignancy indicators (RMI) in preoperative diagnostic of ovarian cancer. Material and methods: The study of 224 ovarian cancer patients, hospitalized at Gynecological Department in Municipal Hospital No 2 in Ruda Śląska was performed. The bimanual examination, transvaginal ultrasound, the serum Ca 125 level estimation and detailed interview were accomplished. Verification of adnexal masses was based on postoperative histopathological examination. According to the data in the literature, the classification of the USG pictures was performed. The RMIs were calculated according to the algorithms presented in the literature. The performance of the indices was estimated by ROC curves. Results: In the analyzed group, 193 of the masses were benign and 31 malignant. ROC curves for both RMIs were similar. Conclusions: 1. The risk of malignancy indicators (RMIs) can be useful in preoperative diagnosis of ovarian tumors. 2. Both of compared indices were similar in sensitivity and specificity.
