In an effort to standardize hematopoietic stem cell allograft procedures, the Francophone bone marrow transplantation and Cell Therapy Society (SFGM-TC) organized the 9th Allograft Harmonization Practice Workshop in Lille in September 2018. The purpose of these workshops is to propose a consensual attitude to the centers that wish it. In this workshop, we discuss how to capture the cytogenetic and molecular abnormalities of acute leukaemias, myelomas, myelodysplasias, myeloproliferative syndromes and myelodysplastic/myeloproliferative syndromes in the database common to all European transplant centers called ProMISe and managed by the European Society for Blood and Marrow Transplantation (EBMT). The complexity of cytogenetic and molecular data makes it difficult to enter data into the ProMISe registry. This workshop proposes a tool for input assistance, in tabular form by pathology. The main recommendation for the karyotype remains that of the complex karyotype that must be entered in "Full caryotype". Concerning the molecular anomalies, it is necessary to enter all the items proposed by ProMISe. In reviewing all the sheets proposed by ProMise, we note the absence of some relevant elements that can be added later.
