Higher levels of soluble E-cadherin in cyst fluid from malignant ovarian tumours than in benign cysts.

A major diagnostic dilemma in the clinical gynaecological oncology setting is to preoperatively determine whether a complex ovarian mass is benign or malignant. The cell-cell adhesion molecule E-cadherin has previously been localised in biopsies from both benign and malignant epithelial ovarian tumours. In this study, soluble E-cadherin levels was measured with ELISA-technique in peripheral blood, ascites and cystic fluids from patients (n = 33) undergoing surgery for ovarian cystic masses. The levels of soluble E-cadherin were significantly higher in cystic fluid from cystadenocarcinomas (p < 0.001) and borderline tumours (p < 0.05) as compared to cystic fluid from cystadenomas. In ascites fluid and peripheral blood no significant differences were seen. However, ratios of cystic fluid/peripheral blood levels were significantly higher in cystadenocarcinoma (p < 0.001) and borderline tumours (p < 0.05) as compared to benign tumours. In conclusion, measurements of soluble E-cadherin in cystic fluid from patients presenting with complex ovarian masses may be beneficial in increasing the accuracy of preoperative diagnosis.
