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)

Inclusion Criteria:

patient

• Aged 0 to 17 inclusive
• Followed in the Pediatric Onco-Hematology Department
• Primo-diagnosed with solid or hematological cancer (incident case)
• Having received a first cycle of chemotherapy
• Whose family has psycho-social vulnerabilities assessed by the Froger et al. tool, indicating a need for an IDE to support the family in monitoring the patient.

Exclusion Criteria:

Patient:

• with a dermatosis contraindicating the use of the device
• Refusing to participate in the study
