Title: [Radiation associated leukemia and myelodysplastic syndrome].
Abstract: Leukemias including acute myeloid leukemia (AML), acute lymphocytic leukemia, and chronic myeloid leukemia as well as myelodysplastic syndrome (MDS), male non-Hodgkin lymphoma and MGUS are statistically significant radiation-associated hematopoietic neoplasms. Recently, MDS has been confirmed to increase among atomic bomb survivors. AML/RUNX1 is a critical transcription factor of differentiation and proliferation of hematopoietic stem cells. AML1 point mutations, especially N-terminal RUNT domain in-frame type, are frequently detected in radiaton-associated and therapy-related (rad-t-) MDS/AML. In addition, the point mutations, are frequently associated with additional mutations in receptor tyrosine kinase (RTK)-RAS pathway, including FLT3, N-RAS, SHP2 and NF1. The combination of AML1/RUNX1 mutation and RTK-RAS pathway mutation in hematopoietic stem cells is considered responsible for the oncogenesis of rad-t- MDS/AML.
