Decitabine in combination with G-CSF, low-dose cytarabine and aclarubicin is as effective as standard dose chemotherapy in the induction treatment for patients aged from 55 to 69 years old with newly diagnosed acute myeloid leukemia

摘要

We retrospectively studied 87 patients aged from 55 to 69 years old with acute myeloid leukemia (AML) who received decitabine in combination with G-CSF, low-dose cytarabine and aclarubicin (DCAG) or standard dose chemotherapy as induction therapy. Patients receiving DCAG had a similar overall response rate (ORR) (p = .6105) and complete remission (CR) rate (p = .3615) compared to those undergoing standard induction. The median overall survival (OS) and relapse-free survival (RFS) was also similar between the two groups although more 'older' (aged from 60 to 69 years old) and 'unfit' patients underwent DCAG regimen. Notably, patients in DCAG group experienced significantly fewer infections (75 versus 100%, p = .001). Moreover recovery of platelet count was significantly more rapid in DCAG group. Thus we speculate DCAG is possibly a feasible and safe treatment regimen for the relatively older patients with AML and is as effective as standard induction.
