Although complex approaches in haematopoietic stem cell transplantation (aHSCT) improved substantially in the last decades, considerable proportion of patients still suffer from life-threatening complications including graft versus host disease (GvHD). Great effort has therefore been dedicated to identification of biomarkers of the aHSCT outcome. Recently, prognostic scores for the prediction of GvHD and non-relapse mortality based on circulating molecules, such as tumour necrosis factor receptor-1, IL-33receptor (ST2) and regenerating islet-derived 3-alpha were proposed and evaluated in multicentre studies. Furthermore, several biomarkers, for example, ST2, represent promising targets for therapeutic intervention in severe GvHD. These results bring us closer to the clinical strategies to effectively control complications following aHSCT, and therefore to the tailored stem cell therapy with higher benefits for the patients.
