Prognostic significance of blood count at the time of achieving morphologic leukemia-free state in adults with acute myeloid leukemia
Objective: To explore prognostic significance of blood count at the time of achieving first morphologic leukemia-free state[complete remission (CR, ANC ≥1×10(9)/L and PLT ≥100×10(9)/L) , CR with incomplete PLT recovery (CRp) and CR with incomplete ANC and PLT recovery (CRi) ]in adult patients with de novo acute myeloid leukemia (AML) . Methods: From January 2008 to February 2016, data of consecutive newly-diagnosed AML (non-APL) adults who received continuous chemotherapy in our hospital were analyzed retrospectively. Results: 352 patients were included in the study. 179 (50.9%) were male. Median age was 44 (17-65) years. Using the SWOG cytogenetic classification, 87 (24.7%) , 171 (48.6%) , 46 (13.1%) and 48 (13.6%) patients belonged to favorable, intermediate, unfavorable and unknown categories, respectively. 16 (4.5%) had monosomal karyotype and 41 (11.6%) had FLT3-ITD mutation positive. Best response achieved at the time of achieving first morphologic leukemia-free state was CR in 299 (84.9%) patients, CRp in 26 (7.4%) and CRi in 27 (8.1%) . With a median follow-up period of 16 (2-94) months in survivors, the probabilities of cumulative incident of relapse (CIR) rate, disease free survival (DFS) and overall survival (OS) at 30 months were 47.5%, 46.0% and 58.6%, respectively. Multivariate analyses showed that non-CR (CRp or CRi) , was associated with high relapse rate, shorter DFS and OS. In addition, intermediate or high risk of SWOG cytogenetic classification and FLT3-ITD positive were common unfavorable factors affecting CIR, DFS and OS. Peripheral blast ≥60% at diagnosis was adverse factors affecting DFS. Age ≥48 years and bone marrow blasts ≥67% were associated with shorter OS. Conclusion: Blood count at the time of achieving morphologic leukemia-free state was one of the key markers associated with treatment outcomes in adults with AML.
