Background New evidence has questioned the role of high-dose cytarabine (HDAC) in consolidation therapy of acute myeloid leukemia (AML) in first complete remission (CR1).We performed a meta-analysis to clarify the question.Methods An extensive literature search was conducted to identify randomized controlled trials (RCTs) comparing HDAC with other therapies for AML in CR1 without donor.The pooled hazard ratios (HRs) for overall survival (OS) and relapse-free survival (RFS), and the pooled odds ratio (ORs) for treatment related mortality (TRM) and toxicities were calculated.
