PG - 565-70 AB - Hypermetaphase FISH (HMF), a molecular cytogenetic procedure combining the long term mitotic arrest of bone marrow cultures with detection of a specific chromosomal rearrangement by fluorescence in situ hybridization (FISH), has recently been shown to be effective in determining the frequency of Philadelphia chromosome positive (Ph+) cells in the bone marrow of chronic myelogenous leukemia (CML) patients undergoing treatment. By combining the probe for the Ph chromosome with one for the detection of the X chromosome, we used HMF to monitor the presence of malignant cells within the emerging host cell population in the marrow of a CML patient that had undergone sex-mismatched allogeneic bone marrow transplantation. In successive studies, we detected 0.5% and 1.75% Ph+ cells, respectively, confirmed by Western blot analysis for p210 protein. These readings occurred concordantly with a repopulation of host-derived diploid female cells. Standard G-band cytogenetic analyses did not detect any Ph+ cells at these time points. Intervention with donor lymphocyte infusion reinduced complete remission. This experience indicates that HMF is useful to identify low levels of repopulation by Ph+ cells in the marrow post-BMT at a stage when intervention is most efficacious.
