title: Cultured autografting for juvenile myelomonocytic leukaemia.
abstract: A case of juvenile myelomonocytic leukaemia (JMML) associated with a chromosomal translocation (1;5) is described. Initial cytoreductive therapy failed to control the disease. In the absence of a matched family or unrelated donor, a Dexter-type long-term bone marrow culture (LTBMC) was established. The LTBMC showed preferential growth of normal stem cells over the abnormal clone, allowing a cultured autologous stem cell transplantation to be performed. Despite detection of the t(1;5) from 5 months to 7 years following cultured autograft, the patient remained in haematological remission. Currently the patient is alive and well at 10 years in full cytogenetic remission.
