Summary

In patients with hematological malignancies one of the most substantial findings is the karyotype of bone marrow cells at the time of diagnosis. The detection of clonal chromosome aberrations in diagnostic samples not only confirms a neoplastic or premalignant process but also provides important diagnostic and prognostic information essential for precise disease classification and choice of suitable therapy. Karyotype analysis during the disease course also allows monitoring of the treatment success reflected as well in the revised WHO classification where patients are often classified into the different diagnostic subtypes based on the finding of specific chromosome and/or genetic changes. Recently, also increases the number of advanced treatment approaches that directly or indirectly target the genetic aberrations present in tumor cells. Despite the large development of new sequencing technologies in recent years, cytogenetic analysis supplemented by the molecular cytogenetic methods still remains a very important part of diagnostics of hematological malignancies.

Keywords:
