Abstract:
Objective:To explore age-related clinical characteristics, early responses and outcomes in non-senile adults with de novo acute myeloid leukemia (AML).
Methods:Data of consecutive cases of 18-65 years adults with de novo AML (non-acute promyelocytic leukemia) were reviewed retrospectively. Clinical characteristics at diagnosis, early responses and outcomes across different age groups of patients were analyzed.
Results:1 097 patients were enrolled. 591 (53.9%) were male. Median age was 42 years. Increasing age was significantly associated with decreasing WBC count (P=0.003), increasing PLT count (P=0.034), lower blast proportions in bone marrow (P=0.021). The incidence of NPM1+/FLT3-ITD- increased with age (P<0.001). Multivariate analyses showed that increasing age was associated with low probabilities of achieving morphologic leukemia free state (MLFS) (P=0.053) and complete remission (CR) (P=0.004) and poor overall survival (OS) (P=0.070) in the whole patients population. However, increasing age was not associated with low MLFS rate and poor OS, except low CR rate (P=0.075) in those receiving standard induction regimen instead of low-intensity regimen.
Conclusions:There were significant differences on clinical characteristics, cytogenetics and molecular genetics across different age groups in non-senile adults with de novo AML. In the patients receiving standard induction regimen, age was not associated with MLFS rate and OS.
