Benign And Assiut Scoring Model

Abstract
Background: The differentiation between benign and malignant adnexal masses is vital to decisions regarding clinical management and surgical planning and prognosis in such patients.
The aim of Study : to evaluate the ability of four versions of RMI (RMI 1, RMI 2, RMI 3 and RMI 4) ,CA-125 and Assiut Scoring Model (ASM). to distinguish a benign from a malignant ovarian masses in Woman Health Hospital, Assiut university, and to assess the accuracy of the different types malignancy risk indices in comparison to Assiut scoring model in preoperative discrimination of benign from malignant ovarian masses in Woman Health Hospital, Assiut university.
Methods: A prospective cross- sectional study was conducted on 60 women with adnexal
There were two teams worked on the data one team for calculation of RMI and the other team blindly from the RMI and CA125 value calculate the Assiut scoring model. The four indices of risk of malignancy indices were calculated for all patients, Ultrasound scans scored as one point for each of the following characteristics: multilocular cyst, solid areas, intra-abdominal metastases, ascites, and bilateral lesions. For each patient a total ultrasound score (U) was calculated. The difference of the first three RMI is based on the allocation of the U and M scores.RMI 4 include other parameter which is tumour size (S) , according to the following equations:
1. RMI 1 [14] = U x M x CA-125, where a total ultrasound score of 0 made U =0, a score of 1 made U =1, and a score of ≥2 made U =3; premenopausal status made M =1 and postmenopausal M =3. The serum level of CA-125 was applied directly to the calculation.
2. RMI 2 [14] = U x M x CA-125, where a total ultrasound score of 0 or 1 made U =1, and a score of ≥2 made U =4; premenopausal status made M =1 and post-menopausal M =4. The serum level of CA-125 was applied directly to the calculation
