Leukemia,Myeloid, Chronic

Gut microbiome (GM) is acquiring increasing importance in human health and disease. GM influences hematopoiesis and immune cells types differentiation. Patients with cancer are characterized by dysbiosis and compromised immunity. In the case of Chronic Myeloid Leukemia (CML), treatment with Tyrosine Kinase Inhibitors (TKIs) restores immunosurveillance; in particular deep molecular response (DMR) is associated with increased levels of NK and CD8+ Tcells. There is no literature on the effects of GM on CML outcomes. This project aims to identify a microbial signature associated with a higher probability of achieving DMR.

French prospective multicenter, open-label study involving newly diagnosed CML patients. Two assessments will be performed during the follow-up of these patients: individual frailty using geriatric tools and individual biological aging determined by DNA methylation analysis.
