Immunological Follow-up After Allogeneic Hematopoietic Stem Cell Transplantation

Description of the evolution of the biological characteristics of immune blood populations and biomarkers of interest in patients who have received allogeneic hematopoietic stem cell transplantation.

Biomarkers Impact Evaluation on the Post-transplant Immune Response After Allografting of Hematopoietic Stem Cells

Chemotherapy or targeted therapy are usually used to treat hematological pathologies. Despite of medical improvement, some of these pathologies present drug resistances, or high risk of relapse. Hematopoietic stem cell (HSC) transplantation remain the gold standard of consolidation, to maintain a durable response. In this situation, allograft with hematopoietic stem cells donor aims at producing Graft-versus-Tumor effect, by producing a new immune system, reproducing anti-tumoral immunity. However, all hemopathies do not have the same sensibility. Nowadays, mechanisms underlying this phenomenon remain poorly understood. Indeed, few data precisely document the expression of immunological checkpoints and other biomarkers in the context of allogeneic HSC transplantation, particularly their impact on post-transplant outcome.

Characteristics and Results of Patients Treated by Therapeutic Intensification

Many studies have focused on patients treated with allogeneic peripheral stem cell transplantation; few studies have until now been carried out to describe the characteristics and results of autografted patients and to attempt to determine possible prognostic factors. However, it is estimated that nearly 5% of autograft patients require MIR care. The investigators therefore wish to conduct a retrospective study including patients treated by therapeutic intensification followed by autograft of hematopoietic stem cells and admitted to the MIR department of the Hautepierre hospital of the University Hospitals of Strasbourg (HUS) within thirty days following initiation of chemotherapy.
