A subgroup of therapy-related myeloid neoplasms (t-MN), associated with a treatment of an unrelated neoplastic or autoimmune disease with cytotoxic agents, like cyclophosphamid, platins, melphalan and others. The neoplastic cells typically harbour unbalanced aberrations of chromosomes 5 and 7 (monosomy 5/del(5q) and monosomy 7/del(7q)) or a complex karyotype. It usually presents with multilineage dysplasia and cytopenias 5-10 years after exposure, with symptoms related to the degree of bone marrow failure and the corresponding cytopenia (fatigue, bleeding and bruising, recurrent infections, bone pain). |

A subgroup of therapy-related myeloid neoplasms (t-MN), associated with treatment of an unrelated neoplastic disease with cytotoxic agents, like etoposide, doxorubicin, daunorubicin and others. The neoplastic cells often show rearrangements involving the mixed lineage leukaemia gene at 11q23. This subgroup of t-MN is typically associated with overt leukaemia, without preceding myelodysplastic syndrome, developing 2-3 years after exposure, presenting with non-specific symptoms related to ineffective haematopoesis (fatigue, bleeding and bruising, recurrent infections, bone pain) and/or extramedullary site involvement. |

A subgroup of therapy-related myeloid neoplasms (t-MN), associated with treatment of an unrelated neoplastic disease with radiation. The neoplastic cells typically harbor unbalanced aberrations of chromosomes 5 and 7 (monosomy 5/del(5q) and monosomy 7/del(7q)) or a complex karyotype. Patients frequently present with multilineage dysplasia and cytopenias 5-10 years after exposure. |
