Abstract
Secondary AML (sAML) has a poor prognosis with conventional chemotherapy alone. Allogeneic hematopoietic cell transplantation (HCT) is beneficial for high-risk AML. Data comparing outcomes of transplants for patients with de novo and sAML are limited. We compared outcomes of patients transplanted for de novo and sAML in first complete remission and investigated the effect of age, HCT comorbidity index (HCT-CI) and karyotype in both groups. A total of 264 patients with de novo (n=180) and sAML (n=84) underwent allogeneic HCT between 1999 and 2013. Median age at transplant was 51 years (range 18–71), median follow-up of survivors was 77 months. Evaluation of all patients demonstrated no significant difference between de novo and sAML for overall survival (P=0.18), leukemia-free survival (P=0.17), cumulative incidence of relapse (P=0.51) and non-relapse mortality (P=0.42). Multivariable and propensity score analyses confirmed the comparable outcomes between de novo and sAML post transplant. Although sAML demonstrates outcomes inferior to de novo AML treated with chemotherapy alone, outcomes following allogeneic HCT are comparable between the two groups.
