Evaluation of Risk of Malignancy Index in the Preoperative Assessment of the Patients with Ovarian Mass

Abstract

Background: Adnexal masses indicate a variety of gynecological and non-gynecological disorders, which may be benign or malignant. Early detection of malignancy is crucial to a proper planning of treatment and improvement of survival. Objective: The purpose of the study was to evaluate predictive value of risk of malignancy index (RMI) in differentiating between benign and malignant ovarian masses preoperatively. Study Design: Cross sectional (Validation) study. Settings: Obstetrics & Gynecology Department of Madinah Teaching Hospital affiliated with University Medical & Dental College Faisalabad Pakistan. Duration: One year from January 2018 to December 2018. Methodology: Total 86 patients were included in the study. Ultrasound was performed then staging laparotomy done followed by histopathological examination. Results: A total of 86 patients were included in the study. Out of which 50 patients (58.1%) were premenopausal and 36 patients (41.9%) were menopausal. The mean age of the patients was 55.79 years. According to histopathological examination of the specimens 44 were malignant and 42 were benign. The sensitivity of the RMI for malignant ovarian tumor is 70.45% and specificity is 69.05%. Conclusion: RMI was considered to have significant importance in preoperative evaluation and treatment of women with an adnexal mass, and was helpful in-patient referral to higher Centre for suitable and effective surgical intervention.
