PG - 175-8 AB - Bone marrow from 5 patients with acute myeloid leukemia with inversion 16, inv(16), was studied by a combination of fluorescence activated cell sorting (FACS) and fluorescence in situ hybridization (FISH) to establish the extent of cell-lineage involvement of inv(16). In all cases, interphase FISH demonstrated the inv(16) in 80-92% of blasts, monocytes, granulocytes, and a proportion of B-cells (21-41%). In contrast, inv(16) was not detectable above threshold levels in mature T-cells. The current study provides a direct evidence for the clonal involvement of myeloid lineage cells and B-lymphocytes and suggests that T-cells are not part of the malignant clone in this disease.
