Prognosis of the<unk>  depends heavily on the speed of its progression to bone marrow failure, myelodysplasia with excessive blast cells, or acute myeloid leukemia. Intervention with non-myeloablative hematopoietic stem cell transplantation before development of the latter two disorders is thought to improve survival indefinitely in most cases. While not yet tested, this transplantation intervention would seem to offer a similar benefit in cases of severe, potentially lethal bone marrow failure.
