This book provides an overview of the latestdevelopments in the concepts and management of ovarian cancer. The new datapresented throughout opens the way to radically different therapeuticapproaches. Surgery remains the core of ovarian cancer treatment, but itsultimate goal and the standard surgical procedure have evolved, giving rise tothe question of how to label expert centers for debulking surgery. Neo-adjuvantchemotherapy is becoming more popular and is also a new field for testing noveldrug combinations. Over recent years, ovarian cancer managementhas embraced molecular biology. It is now more correct to talk about cancers ofthe ovary rather than ovarian cancer, since it is not a unique disease butseveral entities with different molecular drivers. The significant advances indrugs targeting the microenvironment or the tumor cell DNA repair mechanismsare presented in detail together with exciting future perspectives. All these advances would not have been possiblewithout collaborative groups such as the GINECO group in France and theirintegration in wider clinical research networks at the European (ENGOT) andinternational (GCIG) level.
