It is known that treatment outcome could be positively associated with treatment intensity. However, tolerance of chemotherapy decreases in the elder, some patients could not tolerate standard (SD) therapy and even died of side effect, and overall survival (OS) might not be prolonged. Whether all elder acute myeloid leukemia (AML) patients could benefit from SD therapy, or some should receive reduced-intensity therapy or even only supporting care remains controvertal. In this multi-center study, we are going to evaluate the benefit of SD and non-SD (NSD) therapy in elder AML patients.

Whether all elder acute myeloid leukemia (AML) patients could benefit from SD therapy, or some should receive reduced-intensity therapy or even only supporting care remains controvertal. SD therapy is definited as the treatment regimen must follow NCCN guildline and chemotherapy intensity could not be reduced. Non-SD (NSD) therapy is definited as patients receiving reduced-intensity therapy or only supporting care. In this multi-center study, we are going to evaluate the benefit of SD and NSD therapy in elder AML patients.
