[Development and validation of a tool for the systematic identification of social vulnerabilities in cancer patients: the DEFCO tool].

Introduction: Literature suggests that patients from deprived backgrounds are less likely to adhere to their treatments, continue to expose themselves to risk factors and, as a result, have poorer health outcomes. It is therefore crucial to identify these vulnerable populations early on, in order to provide them with tailored and reinforced care. The primary aim of this research is to construct and validate a systematic screening tool for identifying patients at highest risk of social vulnerability due to deprivation, through the use of psychometric techniques.

[Coordination in oncology, pivot nurses].

The function of the pivot nurse was created when the Cancer Plans were first introduced to improve patient management and has constantly developed since then. It is an essential role for the coordination of care and the different players involved along the patient's care pathway.
