Abstract OBJECTIVE: Plasma fibrinogen is a key acute phase protein and known to be elevated in ovarian cancer. We aimed to investigate the association between plasma fibrinogen and malignant and benign ovarian tumors. METHODS: In a retrospective, single-center study, we evaluated preoperative plasma fibrinogen levels in 471 patients with benign and in 224 patients with malignant (borderline ovarian tumor [BOT]: n=36, epithelial ovarian cancer [EOC]: n=188) ovarian tumors. The association between preoperative plasma fibrinogen levels and clinico-pathological parameters was investigated. A multivariate logistic regression model was performed to identify an independent association. RESULTS: Mean (standard deviation) preoperative plasma fibrinogen levels in patients with benign ovarian tumors, BOT, and invasive ovarian cancers were 346.7 (99.7), 372.8 (114), and 472.6 (148.4) mg/dL, respectively (p<0.001). Within the EOC cohort, patients with advanced stage disease had higher plasma fibrinogen levels (485.5 [151.3] mg/dL) than patients with early stage disease (430.9 [130.3] mg/dL; p=0.03). In a multivariate model plasma fibrinogen was identified to be independently associated with the presence of BOT and EOC. In the subgroup of patients <50 years, plasma fibrinogen levels remained independently associated with malignant ovarian tumors in CA 125 positive and negative patients. CONCLUSION: Plasma fibrinogen levels are independently associated with malignant ovarian tumors. Plasma fibrinogen levels showed an independent association with malignant ovarian tumors in the subgroup of patients <50 years, in whom differential diagnosis of ovarian tumors is particularly challenging.
