Abstract

Using T-depleted BM from HLA-identical sibling donors we have performed 36 BMTs since 5/83 in first remission (CR1) of acute leukaemia (AL). Standard conditioning for BMT consisted of Cy 60 mg/kgx2 and 7.5 Gy single fraction TBI (n=27). Six patients received Ara-C 3 g/m2x6, cy 45 mg/kgx2 and 7.5 Gy, while 3 received Cy 60 mg/kgx2 radiation. T lymphocytes were depleted in vitro with 2 murine McAbs (MBG6 + RFT8, n = 17; or RFT8 + RFT12, n = 13; or RFT2, RFT8 + RFT 12, n = 6) plus rabbit c'-mediated lysis. No immunosuppressive therapy was given in the absence of graft-versus-host disease (GvHD). Of 34 patient evaluable for aGvHD, 4 had grade I, 2 grade II and 1 grade III. Chronic GvHD occurred in 3 of 22 evaluable patients (> 150 days). There have been 13 deaths but only 1 from leukaemic relapse (CNS). The mean KS of surviving patients is 86% and actuarial disease-free survival is 53% at 40 months or 65% in those having 'standard conditioning'. The previous major problems of GvHD and leukaemia relapse appear to have been largely overcome. The major risk factor now is infection, particularly pneumonitis, and this problem is surmountable.
