Serum C-reactive protein in the differential diagnosis of ovarian masses.

Objective: A number of serum tumor markers have been investigated to aid clinicians in the differential diagnosis of ovarian masses. Serum C-reactive protein (CRP) is a widely used biomarker of inflammation and has been previously shown to be a promising biomarker in patients with ovarian cancer.

Study Design: In a retrospective single-center study, we evaluated serum CRP in 576 patients with benign and in 242 patients with malignant (ovarian tumors of low malignant potential [LMP]: n=44, epithelial ovarian cancer [EOC]: n=198) ovarian masses.
