The factors affecting early death after the initial therapy of acute myeloid leukemia.

There are some improvements in management of acute myeloid leukemia (AML). However, induction-induced deaths still remain as a major problem. The aim of this study is to assess clinical parameters affecting early death in patients with AML. 199 AML patients, who were treated with intensive, non-intensive or supportive treatment between 2002 and 2014 in Hacettepe Hematology Department, were analyzed retrospectively. In our study early death rate for elderly was found to be lower than previous reports whereas it was similar for those who were under age of 60. Better ECOG performance (ECOG performance score 0 and 1) and non-intensive treatment associated with lower early death rates, however APL-type disease associated with higher early death rates. ECOG performance score at diagnosis was found to be the most related independent factor with higher rate of early death in 15 days after treatment (P<0.001). Therefore we decided to understand the factors which were related with ECOG. WBC count at diagnosis was found to be the only related parameter with ECOG performance score. Leucocyte count at diagnosis appears like to have an indirect effect on early death in AML patients. It maybe suggested that in recent years there is an improvement in early death rates of elderly AML patients. The currently reported findings require prospective validation and would encourage the incorporation of other next generation genomics for the prediction of early death and overall risk status of AML.
