| Clinics and Pathology |
| Disease | Treatment related acute myeloid leukaemia (t-AML) |
| Phenotype / cell stem origin | Only 2 cases to date, a M4-AML and a case with no data |
| Clinics | A 7 year old boy presented with M4-AML 67 months after treatment of a T-ALL with epipodophyllotoxins |
| Prognosis | No data |
| Genetics |
| It is likely that RUNX1 was involved in the translocation. RUNX1, also called AML1 or CBFA2, is a transcription factor, critical regulator of hematopoietic-cell development, involved in many de novo and treatment related leukaemias. |
| Cytogenetics |
| Additional anomalies | The patient also had a t(11;19)(q23;p13) and a complex karyotype with other (non-recurrent) anomalies |
| To be noted |
| Additional cases are needed to delineate the epidemiology of this rare entity: you are welcome to submit a paper to our new Case Report section. |
