Abstract:
OBJECTIVE: The purpose of this study was to design a new scoring system for differentiation between benign and malignant ovarian masses and to assess effectiveness of new scoring system comparing other scoring systems. METHODS: This study was based on 199 women who visited Soonchunhyang Hospital for surgery of ovarian mass. Ultrasonography and scoring system based on De Priest, Sassone, Ferrazi and Alcazar was performed the day before operation. Pathologic diagnosis after operation was directly compared with diagnosis of scoring system. The cut-off level of the new index is 11 points. This study was evaluated by sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS: Parameters of new scoring system were wall thickness, number of septum, volume of mass, irregularity, vascularity and echogenicity. The new scoring system had sensitivity 73.9%, specificity 97.7% and negative and positive predictive values of 96.6% and 80.9% respectively. CONCLUSION: Sensitivity of new scoring system was similar to previous ones but specificity of that is higher. Our new scoring system shows better to differentiate benign from malignant ovarian mass than four other scoring systems.
