Autologous reconstitution combined with durable leukemic remission after allogeneic BMT for CML: absence of persistence of a donor-derived T cell effector population

Abstract

We report a case of autologous hematopoietic recovery with durable leukemic remission after BMT from a phenotypically HLA-identical donor in a 30-year-old male with CML. Graft loss was diagnosed from day 60 post-BMT by VNTR PCR. To assess for the presence of a minor donor-derived T cell population that could exert an anti-leukemic effect, we serially applied a sensitive process of chimerism analysis by fluorescent PCR on sorted T cells. No residual donor T cells could be detected. We also showed retrospectively that a very sensitive method of MRD analysis by real-time quantitative PCR could have permitted prediction of relapse in this case. Bone Marrow Transplantation (2001) 28, 717–720.
