Abstract
Background
The innovative combination of all‐trans retinoic acid (ATRA) and arsenic trioxide (ATO) has established a new chapter of curative approach in acute promyelocytic leukemia (APL). The disease characteristics and prognostic influence of additional cytogenetic abnormalities (ACA) in APL with modern therapeutic strategy need to be elucidated.
Methods
In the present study, we retrospectively investigated disease features and prognostic power of ACA in 171 APL patients treated with ATRA‐ATO‐containing regimens.
Results
Patients with ACA had markedly decreased hemoglobin levels than that without ACA (p = 0.021). Risk stratification in the ACA group was significantly worse than that in the non‐ACA group (p = 0.032). With a median follow‐up period of 62.0 months, worse event‐free survival (EFS) was demonstrated in patients harboring ACA. Multivariate analysis showed that ACA was an independent adverse factor for EFS (p = 0.033). By further subgroup analysis, in CD34 and CD56 negative APL, patients harboring ACA had inferior EFS (p = 0.017; p = 0.037).
Conclusions
To sum up, ACA remains the independent prognostic value for EFS, we should build risk‐adapted therapeutic strategies in the long‐term management of APL when such abnormalities are detected.
