This study aims to investigate the effect of involved-field radiotherapy for recurrent ovarian cancer after primary standard treatment. We will investigate whether the addition of involved-field RT improves 2-year PFS in those patients than that of historical data (only with other standard salvage treatments as systemic chemotherapy ± maximum tumor resection).

| 2 years after radiotherapy |
| Chemotherapy-free interval (The interval to delay the need for a new chemotherapy regimen for disease progression) | It means the interval between the last date performing the previous chemotherapy (before the start of involved-field radiotherapy) and the first date performing the new regimen of chemotherapy (for the disease failures after the involve-field radiotherapy). We want to measure this interval because we want to check the capability of involved-field radiotherapy to delay the need for the new regimen of chemotherapy for the progressive diseases. | 2 years after radiotherapy |
