HAPLO-FANCONI: Observational Follow-up Study of Haplo-identical Transplants in Fanconi Disease
Study Details
Study Description
Brief Summary
This observational protocol will allow for an independent, prospective evaluation of the improvement in survival of patients with Fanconi disease in hematological deadlock due to the absence of an HLA-identical donor and having received a haploidentical transplant.

Detailed Description
Fanconi's disease is characterised by a constitutional defect in DNA repair which results in the occurrence of bone marrow failure and haematological malignancies, mainly myeloid: at the age of 40, the cumulative incidence of these two types of pathology reaches almost 100%. The only curative treatment for haemtalogocial diseases is allogenic hematopoietic stem cell transplant. Transplantation modalities must be adapted to the particular susceptibility of these patients to DNA bridging agents and radiotherapy. HSC transplantation is indicated with an unaffected matched related or matched unrelated donor when the patient has severe bone marrow failure or a poor prognostic clonal evolution (cytogenetic evolution or proven haemopathy). Alternative transplants (9/10 pheno-identical, haplo-identical and placental blood donors) were no longer proposed in most cases due to the frequency of severe complications (graft-versus-host disease, viral infections) and the catastrophic medium-term survival of around 40% (Dufort, Bone Marrow Transplant 2012, Gluckman Biol Blood Marrow Transplant. 2007). The development over the last decade of new haploidentical or phenoidentical 9/10 transplant protocols with unmodified grafts and GVH prophylaxis with post-transplant cyclosphosphamide or ex vivo T-depletion adapted to the particular susceptibility of patients with Fanconi disease has reduced the incidence of these severe complications.
This observational protocol will allow for an independent, prospective evaluation of the improvement in survival of patients with Fanconi disease in hematological deadlock due to the absence of an HLA-identical donor and having received a haploidentical transplant

- Quality of Life questionnaire for adults [At inclusion]
Quality of life will be assessed for adult using "European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ) " EORTC QLQ-C30-V3 questionnaire.The QLQ-C30 is composed of both multi-item scales and single-item measures. All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level.

- Quality of life questionnaire for minors [At inclusion]
Quality of life will be assessed for minor using The Pediatric Quality of Life Inventory™ (PedsQL™) The 36-item PedsQL™ Family Impact Module is a parent-report instrument designed to assess the impact of pediatric chronic health conditions on parents and the family.
