Overview
The observational study aimed at evaluating the incidence of systemic mastocytosis associated with t(8;21) AML in patients with de novo t(8;21) AML and their responses to first induction, and the prognosis from standard therapy.
Description
This is a multicenter, retrospective and prospective, observational study that aims to collect clinical information on patients with systemic mastocytosis associated with t(8;21) AML from September 2022 to August 2023. No intervention is expected.
The purpose of this study is to identify and characterize the patients with systemic mastocytosis associated with t(8;21) AML, t(8;21) AML without systemic mastocytosis, and OSM (Oligo-mastocytic SM) with associated t(8;21) AML.
In order to estimate the incidence of systemic mastocytosis associated with t(8;21) AML, a survey will be sent every month to all participating sites to collect the number of all diagnoses of systemic mastocytosis associated with t(8;21) AML, t(8;21) AML without systemic mastocytosis, and OSM with associated t(8;21) AML. All patients will be followed until August 2025 in order to have at least 2 years of observation.
