[The observatory of rare malignant gynecologic tumors].

The observatory of gynecological rare tumors (TMRG) has been initially created for ovarian rare neoplasms (TMRO). Because of the similarities between ovarian and other gynecological tumors, this observatory has been then extended to all gynecological rare tumors. The recognition by INCa of three national expert centers (centre Léon-Bérard, hôpitaux de Paris, institut Gustave-Roussy) in rare gynecological cancers and a network of regional expert centers in 2010, expend the experience of the website "Observatoire francophone des tumeurs rares de l'ovaire". The major goals of this gynecology rare tumors experts network, are to promote systematic second opinion for initial diagnostic by experts in gynecopathology, systematic multidisciplinary advice by surgeons and medical oncologist experts, to disseminate clinical guidelines dedicated to rare gynecological tumors, to promote specific fundamental and translational research within clinical trials dedicated to rare tumors. At the end, we would like to improve benefit in term of survival and/or fertility for all these potential young patients.
