RESUMEN
The Ethics committee of Gustave Roussy cancer center is devoted to both reflection and action. The group has 40 members, professionals, patients and outside experts. These meet in plenary meetings or in specific working sessions and intervene at the request of any professional faced with ethical questions in the care. This Ethics Committee has voluntarily a double vocation: on one hand, a reflective group on major issues of ethics in health and its involvement in hospital life; on the other hand, a working group embedded in the daily lives of the care. The themes addressed at the meetings (plenary sessions, annual meetings) include shared-decision making, advance directives, refusal of care, religious aspects, or biomedical research Daily activity centered on the care revolves around several times a week meetings, in various services, "Supportive Collegial Meetings" such as proposed in the 3rd French Cancer Plan; these include nursing staff members, oncologists, intensive and palliative care specialists, psychologist, around difficult medical and/or ethical situations. In case of situation requiring an urgent discussion, a referral to the Ethics Committee brings together within 24hours four to five members of the Committee and the care team. Moreover, the Ethics Committee helped develop Aid to Decision making Form upon care gradation for hospitalized cancer patients. Through these interventions on a daily basis, assistance of professionals, reflexive vocation or even delivery of training, the Ethics Committee contributes to an acculturation around anticipation and collegiality in the care. Its double polarity aims to reconcile "philosophical time' for the ethics process, and the connection with the routine issues raised by patients, their families and caregivers.
