Summary Chromosome studies were performed in 24 patients who underwent allogeneic bone marrow transplantation (BMT) for severe aplastic anaemia (8), chronic myeloid leukemia (5 in chronic, 2 in accelerated phase and 1 in lymphoid blast crisis), acute myeloid leukemia (6), acute lymphoblastic leukemia in relapse (1) and Hodgkin's disease (1). Donor-cell type engraftment was demonstrated in 21 patients: in all 17 sex-mismatched transplants and — as demonstrated by reconstitution with Ph-negative cell populations — in 4 CML patients with a sex-matched donor. Recipient-type mitoses were seen in the bone marrow of 5 cases (1 SAA, 3 CML, 1 AML) after transplantation. They were only observed on one occasion in patients with SAA (4 of 25 on day 33) and AML (44 of 50 on day 14). Despite the continued demonstration of some Ph-positive mitoses in 3 patients with CML up to day 28, 323 and 451 after BMT, respectively, all surviving CML patients are still in complete haematological and clinical remission. So far the significance of these cytogenetically abnormal persisting host cells remains unknown.
