    Abstract:
    Seven patients with relapsed acute leukemia (4 ANLL, 3 ALL) and one with juvenile chronic myelomonocytic leukemia (JCMML) received a second BMT (BMT2). Patients were conditioned with CY/TBI (n = 7) or BU/CY (n = 1) for the first BMT (BMT1), with adequate recovery in all and without the appearance of acute GVHD (n = 3) or with mild forms (grade I, n = 2; grade II, n = 3). Relapse after BMT1 occurred in < 6 months (n = 2), between 6 and 12 months (n = 5) and > 12 months (n = 1), and the interval from BMT1 to BMT2 was < 6 months (n = 1), from 6 to 12 months (n = 5) or > 12 months (n = 2). Conditioning for BMT2 was done in untreated relapse and included combinations of BU/CY (n = 2), CY/TBI (n = 1) or BU 1 mg/kg at intervals of 6 h by mouth on days -7 to -4 and melphalan 180 mg/m2 i.v. on day -2, with the addition of VP-16 in the patient with JCMML. Two patients died on day +11 with no evidence of residual leukemia at autopsy. Six patients engrafted, one of whom had an uneventful BMT2, but he relapsed 6 months later. The other five developed severe acute GVHD (grades III-IV), with a fatal outcome in three cases, while two responded to treatment and are currently alive in continuous CR at 12 and 36 months. All patients had received conventional prophylaxis against acute GVHD.(ABSTRACT TRUNCATED AT 250 WORDS)
