Our purpose in this study is to explore the feasibility of treatment of non promyelocytic Acute myeloid leukaemia on elderly patients. We select ten patients with age further than 60 with comorbidity and treat by low dose cytosar subcutaneous plus arsenic trioxide for ten days in month. We will assess overall response rate and overall survival in end of one year.

Acute myeloid leukemia is a disease in which characterised by blast further than 20% in bone marrow plus incomplete differentiation. Many of this patients are elderly with age further than 60 years(CALGB,ECOG,EORTC) or 55 years (SWOG). Mortality rate fallowing standard therapy of this patients is high that can reach to 50%. One of methods to apply a remission with least mortality and morbidity and also significant lower cost effects compare to historical and conventional standard regimen is low dose cytosar and arsenic trioxide combination that has been reported complete remission to 34%.

We select ten patients with age further than 60 with comorbidity and treat by low dose cytosar subcutaneous plus arsenic trioxide for ten days in month. We will assess overall response rate and overall survival in end of one year.
