Cytogenetic study concerned 24 patients. In 13 cases the karyotype was pathological with deletion 5 q in 64% of cases. Seventeen patients have received a chemotherapy. Survival rate to 36 months is 11%. At the time, the only curative treatment is the bone marrow transplantation, which is proposed to young patients with HLA identical donor.
