[Ovarian cancer from the standpoint of medical oncology].

Ovarian cancer is chemosensitive. Staging surgery followed by the first line chemotherapy is recommended no matter the stage. For recurrent disease, it is difficult to prolong the survival by chemotherapy. The goal is palliation. When primary debulking surgery can not be achieved because of patients' status, neoadjuvant chemotherapy followed by interval debulking surgery should be considered, although it is still in clinical-trials.
