About

Prospective study to decipher the clonal architecture of ASXL1-mutated primary and secondary myelofibrosis and its impact on prognosis

Full description

The clonal architecture of myelofibrosis patients is still little described. Inconsistent results in terms of the prognostic value of some mutations are observed in the literature, in particular concerning ASXL1 mutations. We assume that a better understanding of the clonal architecture of ASXL1-mutated myelofibrosis could help refining the prognostic impact of ASXL1 mutations.

This study aims to evaluate a multicenter cohort of 50 patients. Blood of patients will be collected within 18 months of diagnosis. After 4 years of follow-up of the patient as part of his usual care, data on survival and leukemic transformation will be collected.

Enrollment: 50 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
