The Eugène Marquis Centre conducts clinical trials promoted by pharmaceutical laboratories and institutional groups such as UNICANCER, the European Organisation for Research and Treatment of Cancer (EORTC), Comprehensive Cancer Centres and university hospitals. It has developed a close partnership with Rennes University Teaching Hospital in the area of clinical research.
The Centre Eugène Marquis is a Private Health Establishment with Collective Interests (Etablissement de Santé Privé d'Intérêt Collectif) (ESPIC). With its vocation as a university hospital it is a non-profit-making establishment and is a participant in the public health hospital service.
A recognized public utility foundation, the Centre Eugène Marquis founded in 1923, is one of the 20 Centres de Lutte Contre le Cancer (Centres in the Fight against Cancer) (CLCC) set up by the Ordinance of 1945 and since then regrouped under the umbrella of the Fédération Française des Centres de Lutte contre le Cancer (French Federation of Centres for the Fight against Cancer).
