Impact of a Telemonitoring Device on the Occurever at Home in Children at Risk of Chemotherapy-Induced Neutropenia

Brief Summary

The goal of this clinical trial is to evaluate the feasibility of the study, measured by the acceptability rate of patients to be recruited in a study proposing temperature monitoring at home, by a remote monitoring device or by the visit of an IDE at home (in association with the usual educational sessions), to children at risk of febrile neutropenia, from families with psycho-social vulnerabilities. The main questions it aims to answer are: * Will participants adhere to the telemonitoring system? * Is the intervention feasible, in terms of the device's failure to record temperature data? * Will parents behave appropriately when using the device? * How satisfied will parents and caregivers be? * What will be the physical tolerance of the device? * On an exploratory basis, will the remote monitoring system be effective for months? Researchers will compare : * patients using the telemonitoring device for continuous temperature monitoring at home, in combination with education sessions on temperature monitoring and the device * with patient with temperature monitoring at home by a nurse, 2 times a day, in combination with education sessions on temperature monitoring (without the telemonitoring device at home)
