title: Autologous bone-marrow transplantation in relapsed adult acute leukaemia.
abstract: 24 cases of adult acute leukaemia, of which 21 were evaluable, were treated in irreversible relapse with high-dose piperazinedione and supralethal total-body irradiation (T.B.I.) in conjunction with autologous marrow transplantation (A.B.M.T.). The grafted marrow cells had been collected and stored in liquid nitrogen at the time of remission. In 12 patients the marrow cells were fractionated on discontinuous albumin gradients in an attempt to separate normal cells from residual leukaemic cells. 11 patients achieved complete remission (C.R.); 7 other patients had signs of engraftment but died before C.R. The median remission duration was 4 months (2-14). 6 of 9 acute myeloblastic leukaemia patients, in whom bone-marrow transplantation was the first treatment of relapse, achieved C.R. 4 of 5 patients with acute lymphoblastic leukaemia, whose bone-marrow cells were collected during first remission, reached C.R. Autologous bone-marrow transplantation is a valuable first treatment for acute myeloblastic leukaemia in relapse and acute lymphoblastic leukaemia in second relapse.
