  • Recurrent ovarian cancer is defined as recurrence of disease in a patient who achieved initial complete response to primary therapy
  • Persistent ovarian cancer is defined as having residual disease in the form of elevated tumor markers or microscopic or clinically evident disease in a patient who has completed and apparently responded to initial chemotherapy
