Myelodysplastic syndromes among atomic bomb survivors in Nagasaki: similarities to and differences from de novo and therapy-related cases.

Epidemiological studies for atomic bomb (A-bomb) survivors clearly demonstrated that A-bomb radiation increased the risk of hematological neoplasms, such as acute and chronic leukemia, and myelodysplastic syndromes (MDS) among survivors. Several studies on MDS among survivors investigated its characteristics, and it seems that MDS among survivors has different features from those seen in de novo MDS and therapy-related MDS. In this short review, we describe the differences of clinical features, chromosomal alterations and genome aberrations among them.
