Cytoreductive Surgery in Platinum-resistant Recurrent Ovarian Cancer

Open surgery is conducted by senior doctors in gynecological oncology. The following parameters should be recorded: period of operation, location and number of recurrent lesions, location and number of resected lesions, amount of intraoperative bleeding and blood transfusion, whether R0 is reached, size and distribution of residual lesions, surgical complications, hospital stay, and period to adjuvant chemotherapy. Patients are required to start intravenous chemotherapy within 4W after surgery, at least for 4 cycles.
