We report here a case of donor cell leukemia in a female Ph-positive CML pa
tient who received an allogeneic BRIT from her HLA-identical brother in the
chronic phase and subsequently developed a donor cell Ph-positive ALL. The
number of cases of donor cell leukemia after BRIT so far reported is less
than 20 and in this case, as in the first cases reported by Marmont Et al a
nd McCane et al. the original leukemia and donor cell leukemia share the pr
esence of a Ph chromosome. Furthermore, we analyzed the patient during diff
erent stages of her disease by RT-PCR and determined the type of bcr-abl ju
nctions (M bcr-abl junction; b3a2 transcript, p210) in both the recipient a
nd donor cell leukemia.
