LOG-AFTER software to improve long-term monitoring of childhood cancer survivors

LOG-I - Impact Study of LOG-AFTER Software on Long-term Monitoring of Former Patients (LOG-I - LOG-Impact Study) / Etude d'Impact du Logiciel LOG-AFTER Sur le Suivi à Long Terme Des Anciens Patients (LOG-I - LOG-Impact Study)

Not applicable Interventional University Hospital, Angers · NCT06939322

This project will test whether giving childhood cancer survivors access to the LOG-AFTER app (with optional GP linkage) helps them follow recommended long-term screenings.

What this trial studies

This is a randomized interventional comparison where survivors are assigned to follow-up with or without access to the LOG-AFTER software. For participants given access, an account is created within five days of the visit and their personalized after-cancer plan (PPAC) is recorded; all participants complete the PAM-13 patient activation questionnaire. The system collects treatment history, late-effect and psychosocial data, and can notify the patient’s general practitioner when activated. The main aim is to compare how the digital tool affects adherence to recommended survivorship screenings and patient activation over routine follow-up.

Who should consider this trial

Good fit: Ideal candidates are survivors treated for cancer or malignant hematologic disease before age 25 who are disease-free or stable without treatment for at least 5 years, have three or more recommended screenings in their survivorship plan, have internet access on a computer or smartphone/tablet, and can give informed consent.

Not a fit: Patients unlikely to benefit include those with a relapse or second cancer within the past 5 years, people without internet access or health insurance, and those under legal protection or deprived of liberty.

Why it matters

Potential benefit: If successful, LOG-AFTER could increase adherence to recommended screenings, improve patient activation, and help detect late complications earlier.

How similar studies have performed: Previous digital survivorship and e-health programs have shown modest improvements in follow-up adherence and patient activation, while LOG-AFTER’s radiotherapy details and GP linkage represent a relatively novel combination.
