Abstract: Ovarian cancer is the leading cause of death among gynecological malignancies. Signs and symptoms of ovarian cancer are frequently absent in early stages. It is easily to invade or spread to other parts of the body. So, it is difficult to diagnose until it spreads and advances to later stages. Some patients cannot tolerate the adverse chemotherapy reaction, so the effect of chemotherapy is hardly satisfactory. Moreover, drug resistance is common and recurrent rate of ovarian cancer is high. These challenges lead to the development of drug delivery nanoparticles for ovarian cancer treatment. Based on enhanced permeability and retention effect, domestic and foreign scholars prepare drug delivery nanoparticles and targeted tumor to complete drug release. It helps to enhance efficacy and reduce side effects in vivo and in vitro research. Various drug delivery nanoparticles are developed by different nanomaterials and some combine with gene, immune therapy. Nano-sized carriers can also be functionalized to both diagnose and treat cancer. This review focuses on different types of targeted nanotherapy for ovarian cancer treatment, including passive targeting, active targeting, magnetic targeting, gene targeting, immune targeting and ultrasound targeting.
