We retrospectively analyzed the outcomes of all acute myelogenous leukemia (AML) patients in first remission (n = 44; median age = 48 years; high-risk cytogenetics = 59%) who received unrelated donor hematopoietic cell transplantation (HCT) with myeloablative conditioning regimen of i.v. busulfan, fludarabine, and antithymocyte globulin (ATG) between January 2002 and November 2009 at our institution. Donor-recipient pairs were matched by high-resolution HLA-A, -B, -C, -DRB1, and -DQB1 typing (10/10 matches, n = 41; 9/10 matches, n = 3). With a median follow-up of 34 months, actuarial 3-year event-free survival (EFS) and overall survival (OS) is 70% and 78%, respectively. The 3-year EFS and OS in patients with and without poor risk cytogenetics is similar (63% versus 82%, P = 0.43 and 78% versus 82%, P = .89, respectively). The 3-year EFS and OS is also similar in patients above age 55 year versus patients age 55 year or younger (80% versus 67%, P = .47 and 80% versus 78%, P = .81, respectively). The 100-day and 3-year cumulative incidence of transplant-related mortality is 5% and 15%, respectively. Six patients have relapsed, and 3 of them are alive and in remission after salvage therapy, with a median follow-up of 23 months. These results indicate that the majority of AML patients eligible for this treatment can achieve long-term disease control.
