متن کاملSwitch of the mutation type of the NPM1 gene in acute myeloid leukemia (AML): relapse or secondary AML?
Mutations in exon 12 of the nucleophosmin (NPM1) gene have been described as primary leukemogenic event in up to 35% of adult acute myelogenous leukemia (AML) cases, mainly those with normal karyotype. This type of AML is listed as provisional entity in the World Health Organization classification of tumors of the hematopoietic and lymphoid tissues 2008. NPM1 mutation status has improved risk s...
متن کاملClonal evolution in relapsed NPM1-mutated acute myeloid leukemia.
Mutations in the nucleophosmin 1 (NPM1) gene are considered a founder event in the pathogenesis of acute myeloid leukemia (AML). To address the role of clonal evolution in relapsed NPM1-mutated (NPM1mut) AML, we applied high-resolution, genome-wide, single-nucleotide polymorphism array profiling to detect copy number alterations (CNAs) and uniparental disomies (UPDs) and performed comprehensive...
متن کاملThe FLT3ITD mRNA level has a high prognostic impact in NPM1 mutated, but not in NPM1 unmutated, AML with a normal karyotype.
The impact of a FLT3-internal tandem duplication (FLT3ITD) on prognosis of patients with acute myeloid leukemia (AML) is dependent on the ratio of mutated to wild-type allele. In 648 normal karyotype (NK) AML patients, we found a significant independent effect of the quantitative FLT3ITD mRNA level--measured as (FLT3ITD/wtFLT3)/(FLT3ITD/wtFLT3+1)--on outcome. Moreover, this effect was clearly s...
متن کاملAn intensive approach to treatment for older patients with relapsed isolated NPM1 mutated AML
We present a short case series of elderly patients with NK-AML and isolated NPM1 mutation who were treated with intensive chemotherapy, achieving significant CRs multiple times on reinduction, even with a single course.We hope to highlight the NPM1 as a molecular marker in elderly for consideration of aggressive treatment, even if abridged, as this subset may achieve a durable, good quality res...
