The management of ovarian cancer continues to provide major challenges and debates about optimal treatment. For first-line therapy there remain discussions about optimal chemotherapy for early disease, the use of taxanes as standard for advanced newly diagnosed patients, whether there is a definite role for neoadjuvant chemotherapy and the question of maintenance treatment. For relapsed disease, the management hinges around the distinction between platinum-sensitive and -resistant cancer, and the recent AGO-2.5 and ICON-4 studies suggest that treating with carboplatin and paclitaxel or carboplatin and gemcitabine is recommended. Intraperitoneal chemotherapy remains an enigma with at least three studies showing survival advantage; however, there has been no move to incorporate it into standard management of those patients who achieve complete remission after first-line chemotherapy. Finally, neoadjuvant chemotherapy prior to debulking surgery is the subject of several ongoing clinical trials and may turn out to be one of the most important developments since the concept of interval debulking surgery was established and proven in Europe.
