PG - 701-6 AB - We present a study in which we used a recently described method combining fluorescence in situ hybridization (FISH) and immunophenotyping, i.e. FICTION, to assess the involvement of different cell lineages in myelodysplastic syndrome (MDS) with monosomy 7 (-7), trisomy 8 (+8) or loss of Y chromosome (-Y). Blood or marrow smears or cytocentrifuge preparations were stained both by antibodies to granulocytes (CD15), monocytes (CD14), T lymphocytes (CD3), B lymphocytes (CD20) and by probes specific for chromosomes 7, 8 or Y. Of nine cases of MDS with -7, four with +8 and two with -Y studied, none showed lymphocytic involvement by the chromosome abnormality. In contrast, -7, +8 and -Y were found in granulocytes and monocytes in all patients studied, but they involved a variable proportion of those cells. The partial involvement by -7 and +8 seen in some cases suggests that myelopoiesis was only partially clonal in those cases, or that the chromosome abnormality was a secondary event in the MDS process. FICTION therefore appears to be a simple and easily reproducible method that can be used for the assessment of lineage involvement in MDS and other haematological malignancies.
