Advances in molecular biology techniques during the past decades allowed for the scrutiny of tumor derived biomolecules, including circulating tumor DNA fragments at an unprecedented level. In case of metastatic tumors, the minimally invasive liquid biopsy sampling provides great opportunity to simultaneously detect and monitor genetic aberrations emerging at distinct anatomical sites, and to identify alterations associated with clonal evolution. Consequently, several studies have recently interrogated the utility of liquid biopsy in the analysis of solid tumors, with this approach already being incorporated into the diagnostic workflow of some diseases. In oncohematology, diffuse large B-cell lymphoma, Hodgkin lymphoma and multiple myeloma are the most intensively studied entities in this regard. Based on data previously published by our group and others, the investigation of circulating tumor DNA in hematology has a potential to convey invaluable prognostic information prior to treatment, to detect actionable genetic alterations, to monitor treatment efficacy and minimal residual disease as well as to identify therapy resistant clones. In this review, we provide an overview of the potential applications of liquid biopsy analysis in oncohematology.
