abstract = {To improve monitoring of myeloid neoplasms by flow
cytometry-based minimal residual disease (MRD) analysis, we
analyzed the significance of leukemia-associated
immunophenotype (LAIP) markers in 44 patients.In a pilot
study cohort, peripheral blood or bone marrow samples from
13 patients with myeloid neoplasms and one case of B
lymphoblastic leukemia in complete hematologic remission
after allogeneic bone marrow or stem cell transplantation
were subjected to selection for leukemia-specific phenotypes
by fluorescence-activated cell sorting using individual
marker combinations, followed by PCR-based chimerism
analysis.The feasibility of this method could be
demonstrated, with selection being successful in 12 cases,
including two cases where mixed chimerism was found
exclusively in sorted cells. Interestingly, four specimens
displayed full donor chimerism in cells expressing the
presumably aberrant combination CD34+ /CD7+ . Further
analyses, including assessment of an independent cohort of
25 patients not affected by neoplastic bone marrow
infiltration, revealed that normal myeloid precursors
usually include a population coexpressing CD34, CD13, CD33,
and CD7.We conclude that the combination CD34+ /CD7+ might
not be suitable as an LAIP for MRD diagnostics and that a
subset of normal myeloid precursors in the bone marrow
expresses CD7.},
