[Molecular diagnosis in hematopathology].
The diagnosis of hematopoietic neoplasias has nowadays become more and more refined by molecular cytogenetic and molecular biological techniques. The biological basis of most of these techniques is that (malignant) tumors represent clonal neoplasias that are derived from a single or few progenitor cells, thus imparting a clonal relationship to all daughter cells. Apart from clonality analysis as a marker for neoplastic growth, the presence or absence of certain primary chromosome abnormalities, and the number and the kind of secondary genetic anomalies become increasingly important in the delineation of the biological grade of aggressiveness.
