Evolution from an antecedent chronic myeloid malignancy does not impact survival outcomes in NPM1-mutated AML
Nucleophosmin-1 (NPM1)-mutated AML is a molecularly defined subtype typically associated with favorable treatment response and prognosis; however, its prognostic significance in AML evolving from an antecedent chronic myeloid malignancy is unknown. This study's primary objective was to determine the impact of mutated NPM1 on the prognosis of AML evolving from an antecedent chronic myeloid malignancy. We conducted a retrospective chart review including patients with NPM1-mutated de novo and sAML. sAML was defined as those with a preceding chronic-phase myeloid malignancy before diagnosis of AML. Of 575 NPM1-mutated patients eligible for inclusion in our study, 51 (8.9%) patients were considered to have sAML. The median time from diagnosis of NPM1-mutated chronic myeloid malignancy to sAML evolution was 3.6 months (0.5–79.3 months). No significant differences in leukemia-free (2-year LKFS 52.0% vs. 51.2%, p = .9922) or overall survival (2-year OS 56.3% vs. 49.4%, p = .4246) were observed between patients with NPM1-mutated de novo versus sAML. Our study suggests that evolution from a preceding myeloid malignancy is not a significant predictor of poor prognosis in the setting of an NPM1 mutation. Our study demonstrated a short time to progression to sAML in most patients, which further supports the consideration of NPM1 as an AML-defining mutation.
期刊介绍:
European Journal of Haematology is an international journal for communication of basic and clinical research in haematology. The journal welcomes manuscripts on molecular, cellular and clinical research on diseases of the blood, vascular and lymphatic tissue, and on basic molecular and cellular research related to normal development and function of the blood, vascular and lymphatic tissue. The journal also welcomes reviews on clinical haematology and basic research, case reports, and clinical pictures.
