This will be a multicenter, translational study without any therapeutic intervention. It will be conducted at 7 central laboratories (Hospital Universitari i Politcnic La Fe, Hospital Universitario de Salamanca, Hospital 12 de Octubre, Hospital Universitario Virgen del Roco, Hospital Dr. Negrn de Las Palmas de Gran Canaria, Hospital Reina Sofa de Crdoba and Clnica Universidad de Navarra) belonging to the Spanish PETHEMA Group. The laboratories will receive and process bone marrow and peripheral blood samples of patients with AML at the time of the initial diagnosis or at relapse or resistance (first or subsequent relapse/resistance). The demographic data and clinical characteristics of the patients and of the AML, morphological and molecular response will be collected in case report forms (CRFs). Since the aim of this study is the molecular diagnosis of AML, all patients with AML will be included, regardless of the treatment (or no treatment at all) they receive.

The physicians will receive the report about the molecular diagnosis for FLT3, NPM1, CBF and PML/RARa quickly (<48-96 hours), in order to provide them with knowledge of the mutational status, that may cause changes to be made during the initial management of the disease.

The aim of this project is to set up this rapid screening and diagnostic platform for AML by having specimens sent to 7 centralized reference laboratories across the country, where the molecular characteristics of leukemic cells will be analyzed by qRT-PCR and NGS technologies with high quality standards. This platform will provide homogeneous criteria for assessing the biological characteristics of the different entities that make up the disease.

It is expected that samples of marrow and/or blood of 700 patients with AML will be analyzed per year.
