Folate receptor: a potential target in ovarian cancer

Ovarian cancer is the most frequent cause of gynecological cancer-related death. Unfortunately, many patients are diagnosed at an advanced stage and have a poor prognosis. The standard treatment for advanced disease involves maximal cytoreductive surgery and chemotherapy based on platinum compounds and taxanes. Patients presenting at an advanced stage have a higher risk of recurrence. The development of drug resistance currently represents a major obstacle in the systematic treatment and, therefore, the discovery of new anticancer agents and approaches should improve the poor prognosis of these patients. Folate receptor α is overexpressed in epithelial ovarian cancer (EOC), but has limited expression in nonmalignant human tissues. The degree of folate receptor expression corresponds with the stage and grade of the disease. Because of this, folate receptor α seems to be a potential therapeutic target for the treatment of ovarian cancer. Currently, several approaches have been studied to target this protein in ovarian cancer treatment. This review summarizes current knowledge about the potential usage of folate receptors as prognostic and predictive biomarkers as well as their role in the management and targeted therapy of ovarian cancer.
