[The announcement in pediatric oncology - Feedback on simulation-based training within the GOCE (Grand Ouest cancer de l'enfant - Grand West Childhood Cancer)].

The announcement of a cancer diagnosis is a crucial moment in the management of the disease, as it is the starting point for a relationship of trust between patient and caregiver. In 2005, this issue led to the creation of an announcement system as part of the 2003-2007 cancer plan, but its implementation in practice remains uncertain. Pediatric oncology has its own specificities, with a triangular relationship and the need for doctors to adapt to the child's age.

Either professional or amateurs performers, and sometimes " real " patients, called expert patients, are acting. Actor training and preparation to achieve the simulation sessions should be rigorous.
