- W2981569657 abstract "7055 Background: Comorbidity has been evaluated as an outcome predictor in elderly patients receiving induction chemotherapy for acute myeloid leukemia (AML) as well as in patients undergoing allogeneic hematopoietic cell transplantation (HCT) for various hematologic disorders. In this single-institute retrospective study, we investigated the prognostic significance of comorbidity in younger AML patients. Methods: A total of 276 patients, aged 14 to 59 years, who received standard induction chemotherapy consisting of cytarabine plus daunorubicin or idarubicin for de novo AML excluding M3 subtype between 2000 and 2007 were included. Pre-treatment comorbidity score, assessed by the HCT specific comorbidity index (HCT-CI), was calculated using clinico- pathologic data, which were retrieved from Asan Medical Center Leukemia Registry Database. The HCT-CI score was 0 in 113 patients (40.9%), 1 in 94 (34.1%), and ≥ 2 in 69 (25.0%). Results: In the univariate analyses, the HCT-CI score was not a significant prognostic factor for induction of complete remission (CR), whereas survival outcomes such as overall survival (OS), relapse-free survival (RFS) and event-free survival (EFS) were significantly different according to the HCT-CI scores (Table). The multivariate models showed that the HCT-CI score was an independent prognostic factor for EFS (P=0.044), but not for OS (P=0.301) and RFS (P=0.119). Other independent prognostic factors were age (P=0.001 for OS, P=0.002 for RFS, P=0.006 for EFS), initial leukocyte counts (P=0.006 for CR, P<0.001 for OS, P=0.039 for RFS), initial uric acid levels (P=0.004 for RFS, P=0.001 for EFS), and cytogenetic risk groups (P=0.012 for CR, P<0.001 for OS, P<0.001 for RFS, P=0.005 for EFS). Conclusions: Pre-treatment comorbidity may provide additional prognostic information over established prognostic factors in patients younger than 60 years of age receiving standard induction chemotherapy for de novo AML.
