Immunotherapy for platinum-resistant ovarian cancer
Ovarian cancer is characterized by a high mortality on incidence ratio. Although the majority of patients achieve complete response after primary treatment, approximately 65–80% of patients recur with the first 5 years. Platinum-free interval is one of the main prognostic factors. Patients recurring with 6 months within the end of platinum-based chemotherapy are characterized by poor prognosis. To date no effective treatment modality are identified for those patients. The mainstay of treatment for platinum-resistant ovarian cancer is single agent chemotherapy.
