Methods： Study involved the women treated for adnexal tumors throughout a period of 2 years. On admission, detailed anamnestic and laboratory data were obtained, expert ultrasound scan was performed, and power Doppler index （PDI）, risk of malignancy index （RMI） and body mass index （BMI） were calculated for all patients. Obtained data were related to histopathological findings, and statistically analyzed. Results： The study included 689 women （112 malignant, 544 benignant, and 33 borderline tumors）. Malignant and borderline tumors were more frequent in postmenopausal women （P=0.000）. Women who had benignant tumors had the lowest BMI （P=0.000）. There were significant （P〈0.05） differences among tumor types regarding erythrocyte sedimentation rate, CA125 and carcinoembryonic antigen （CEA） levels. Among ultrasound findings, larger tumor diameter and ascites were more frequent in malignant tumors （P=0.000）. Women with malignant tumors had highest values of RMI and PDI （P=0.000）. Conclusions： Anamnestic data, ultrasound parameters and laboratory analyses were all found to be good discriminating factors among malignant, benignant and borderline tumors.展开更多
