Fourteen patients with chronic granulocytic leukemia received bone marrow grafts from HLA identical siblings. Ten patients were in blast crisis prior to grafting, three were in an accelerated phase of their disease, and one was aplastic secondary to chemotherapy. Prior to transplant all patients were conditioned with chemotherapy including cyclophosphamide plus 1,000 rad of total body irradiation. Ten patients achieved engraftment while four died 1 to 26 days after marrow infusion without functioning grafts. Two patients received a second infusion of donor marrow because of delayed engraftment. Neither marrow cell dose nor presence of myelofibrosis correlated with successful engraftment. Three out of ten engrafted patients developed graft-versus-host disease. Interstitial pneumonia occurred in seven patients. The immediate cause of death was bacterial septicemia in six patients. All evidence of leukemia disappeared in nine out of ten evaluable patients. The median survival was 43 days. One patient had a complete remission of 16 months duration.

The first 72 consecutive bone-marrow transplant recipients with haematological malignancies (29 with acute nonlymphoblastic leukaemia, 31 with acute lymphoblastic leukaemia, nine with CML and three with myelofibrosis, IgA myeloma and T-cell lymphoma, respectively) were investigated for the frequency of relapses 1 year or later after bone-marrow transplantation. Seven relapses occurred from 30 to 850 d after transplantation (median 180 d). All relapses occurred in patients with acute leukaemia less than or equal to 18 years of age with a high risk for relapse, i.e. transplanted in second or later remission or with more than 10% blasts in the marrow before transplantation. Among all patients the probability of relapse was increased in patients without cytomegalovirus (CMV) infection (P = 0.001) and in patients without chronic GVHD (P = 0.049). Among leukaemic patients less than or equal to 18 years of age with a high risk of relapse all relapses occurred in patients (n = 11) without CMV infection, whereas no relapses were seen in patients (n = 13) with CMV infection (P = 0.006). Known risk factors for leukaemic relapse were comparable in both groups.

Nine patients underwent allogeneic bone-marrow transplantation as treatment for chronic granulocytic leukaemia (CGL) during the accelerated phase, a point in the course of the disease when it has progressed beyond the stable chronic phase but before the onset of blast crisis. After bone-marrow transplantation, haematological and cytogenetic studies showed ablation of all evidence of leukaemia, successful engraftment, and persistence of normal haemopoiesis in all patients. In one patient severe myelofibrosis and osteosclerosis disappeared after bone-marrow transplantation. Two patients have died of complications related to graft-versus-host disease (GvHD) but with no evidence of CGL. In one patient haematological and cytogenetic evidence of recurrent disease developed after bone-marrow transplantation, and she survives in chronic phase. Six patients are free of disability, do not require transfusions, possess normal marrow chromosomes, and have persistent clinical and haematological evidence of complete remission from CGL. Intervention with allogeneic bone-marrow transplantation during the accelerated phase of CGL can eradicate the disease and can provide normal haemopoiesis with acceptably low early morbidity and mortality. The long-term efficacy of bone-marrow transplantation as treatment for CGL, and the most effective timing of the transplantation with regard to the course of disease have yet to be determined.

A 28-yr-old woman with acute malignant myelosclerosis received, as primary treatment, ablative chemotherapy and total body radiation therapy followed by bone marrow transplantation from her histocompatible brother. The patient is now well more than 15 mo after bone marrow transplantation, with normal peripheral blood counts, a normal bone marrow, no evidence of graft-versus-host disease, and is on no therapy. In light of the poor results obtained with conventional chemotherapy in this disease, bone marrow transplantation may represent the treatment of choice for patients who have an appropriate donor.

We report a successful ereated case of acute megakaryoblastic leukemia (AMKL) with myelofibrosis (MF), which achieved a disease free condition, with disappearance of MF, for over 24 months after allogeneic bone marrow transplantation (BMT) and summarized cases of MF receiving BMT reported in Japan to evaluate the influence of MF on engraftment of bone marrow (BM). A 40-year-old man was admitted on Jan. 29, 1991 due to anemia and thrombocytopenia. BM aspiration resulted in a dry tap and MF and cells stained positive with anti-GPIIb/IIIa (CD41a) antibody were demonstrated by BM the biopsy specimen. Complete remission was achieved by multi-drug chemotherapy including behenoylcytosine arabinoside, etoposide, mitoxantrone and prednisolone (PLS). After preconditioning with little BU+CY, BMT was performed from an HLA-identical brother on Jan. 16, 1992. From day 9 of post BMT, acute skin graft versus host disease (grade 1) was observed, which was controlled by 60 mg/day of PSL. Engraftment was achieved on day 12. Although cystitis developed, he was discharged on Apr. 5, 1992 and remains disease free. Including the present case, seven allogeneic BMT patient with MF have been reported so far in Japan. Four cases in whom MF recovered before BMT showed better results than other three cases that still showed MF at BMT. Reversal of MF seems to be a favorable pre-transplant factor for successful BMT in patients with MF.

Thirty-one patients (median age, 44 years) with advanced hematologic malignancies were given thiotepa 15 mg/kg, and cyclophosphamide 120 (n = 14) or 150 (n = 17) mg/kg followed by unfractionated peripheral blood stem cell transplants (PBSCT) from genotypically identical siblings (n = 28) or one antigen mismatched family donor (n = 3). Donors were mobilized with granulocyte colony-stimulating factor 5 to 10 microgram/kg/d for 6 days and underwent two to three leukapheresis on days +5, +6, +7. The median cell yield per donor expressed/kg of recipients body weight was as follows: nucleated cells 13 x 10(8)/kg; CD34+ cells 6 x 10(6)/kg; colony-forming unit-granulocyte macrophage 38 x 10(4)/kg, and CD3+ cells 449 x 10(6)/kg. The diagnoses were chronic myeloid leukemia (n = 4), acute myeloid (n = 9) or lymphoid leukemia (n = 2), acute myelofibrosis (n = 2), multiple myeloma (n = 1), lymphoma (n = 6), chronic lymphocytic leukemia (n = 1) myelodysplasia (n = 6). Twenty-eight patients had advanced disease, 29 patients were first grafts, and 2 were second transplants 3 and 9 years after the first. Neutrophil counts of 0.5 x 10(9)/L and platelet counts of 30 x 10(9)/L platelets were both achieved on day +14 (median). Engraftment could be proven by sex markers or DNA polymorphism in 29 of 31 patients: one had early leukemia relapse and one patient was unevaluable because of early death. Acute graft-versus-host disease (GVHD) was scored as minimal or absent (grade 0 to 1) in 14 patients, moderate (grade II) in 13, and severe (grade III to IV) in four. Causes of death were leukemia (n = 4), acute GVHD (n = 4, with associated cytomegalovirus infections in three), sepsis (n = 1), liver failure (n = 1), multiorgan failure (n = 1), and hemorrhage (n = 1). The actuarial transplant mortality is 29%, the actuarial relapse rate 22%. Nineteen patients survive with a median follow up of 288 days (100-690). The actuarial 2-year survival is 57%. Three patients received PBSCT from family donors mismatched for one class II antigen: all engrafted, one developed grade I aGVHD; one died of leukemia on day +155; two are alive disease free 267 to 290 days postgraft. This study suggests that thiotepa cyclophosphamide followed by unfractionated PBSC allograft may be an alternative form of transplant for adults with advanced leukemia, also in the setting of one antigen mismatched donor. The engraftment is rapid with acceptable GVHD and relatively low transplant-related mortality.

We report a patient with poor-prognosis myelodysplastic syndrome (MDS) after successful treatment of lymphoma, who was given an allogeneic BMT, engrafted and achieved complete remission, but later had a relapse of his MDS with complete disappearance of donor haemopoiesis. After two episodes of CMV pneumonia and continued prophylactic use of ganciclovir thereafter, he experienced a spontaneous complete disappearance of all signs of MDS, including myelofibrosis, and a complete return to donor haemopoiesis. This case is the first one to suggest a graft-versus-leukaemia effect (GVL) in MDS patients. It depicts the complex relationship between GVL, graft-versus-host disease (GVHD) and graft rejection. It could also constitute a clinical illustration of the possible antileukaemic effect of CMV infection and its treatment with ganciclovir.

An increasing number of volunteer unrelated donor bone marrow transplantations (VUD-BMT) are performed every year for hematological malignancies due to the availability of a large donor pool. Here we show the results of 36 VUD transplants from our institution using a chemotherapy-only conditioning regimen comprising busulfan 4 x 4 mg/kg and cyclophosphamide 2 x 60 mg/kg. All patients received heparin 200 IU/kg bw continuous i.v. infusion starting the day before conditioning until day +30. Thirty-four of 36 patients (94%) engrafted and no secondary graft failure was observed. The two non-engraftments occurred in patients with CML in blast crisis with extensive myelofibrosis. All 34 engrafted patients (100%) were in complete remission on day +30 as shown by bone marrow biopsy and cytogenetic examinations. No life-threatening treatment-related morbidity or mortality (TRM) were observed, in particular, no severe veno-occlusive disease (VOD) of the liver and no fatal pulmonary complication. Use of G-CSF significantly shortened the time of neutropenia by 5 days. GVHD prophylaxis consisted of CsA/methylprednisolone with or without MTX. Acute GVHD grade II-IV was observed in 18/34 patients (53%) and cGVHD in 12/27 patients (45%), who survived to day +100. In seven patients (four with HLA class I or II mismatch) anti-T-lymphocyte globulin (ATG) was added for acute GVHD prophylaxis. One of seven had aGVHD grade II and none developed grade III to IV GVHD or graft failure. We conclude that Bu/CY is a feasible, save and sufficiently immunosuppressive regimen for VUD transplantation. Severe acute GVHD might be avoided by additional use of ATG in GVHD prophylaxis.

Agnogenic myeloid metaplasia is a rare indication for allogeneic bone marrow transplantation (BMT). We have retrospectively studied 12 patients allografted for this disease within the French BMT group. Prior to BMT, the mean age was 40 years (range 14-49). Diagnosis was based on the Polycythaemia Vera Study Group criteria. Before BMT, 10 patients had been splenectomized, eight required transfusions, and four had received at least two lines of chemotherapy. Cyclophosphamide and total body irradiation was the main conditioning regimen used (n=8). The donor was an HLA-identical sibling except in one case where there was one HLA-DR mismatch. Acute graft-versus-host disease (GVHD) prophylaxis consisted of methotrexate and cyclosporine A. 11 patients engrafted with median times to achieve absolute neutrophil count > 0.5 x 10(9)/l and platelet count > 50 x 10(9)/l of 17 (range 12-44) and 29 (range 12-196) days respectively. One primary graft failure occurred. 10 patients developed grade II-IV acute GVHD, four developed extensive chronic GVHD. One patient relapsed 16 months post-BMT and was untreated and well 14 months later. Three patients died from the BMT procedure. In May 1996 the median follow-up was 25 months and the 4-year overall and event-free survivals were 71% and 59%, respectively. Thus, we conclude that extensive myelofibrosis is not associated with delayed engraftment, and that HLA-identical sibling allogeneic BMT can be considered in a small proportion of patients with agnogenic myeloid metaplasia.

The Bone Marrow Transplantation Program in Belarus was founded in 1992, and in 1993, a Bone Marrow Transplantation Centre was created in Minsk. From February 1994 to April 1996, 19 allogeneic bone marrow, 16 autologous bone marrow and 10 autologous peripheral blood stem cell transplantations were performed. Reasons for transplantation included chronic myeloid leukemia, multiple myeloma, severe aplastic anemia, acute myeloid leukemia, acute lymphoblastic leukemia, progressive myelofibrosis, Hodgkin's disease, non-Hodgkin's lymphoma, and neuroblastoma. Among the patients were two liquidators involved in the Chernobyl cleanup activity, both of whom underwent allogeneic bone marrow transplantation. A variety of ablative preparative regimens were used, and blood progenitor cells were mobilized by treatment with Cytoxan and granulocyte colony-stimulating factor. Therapy-related deaths resulted from graft-versus-host disease, septic shock, veno-occlusive disease bleeding and intestinal pulmonary fibrosis. Because the transplantation procedures were carried out on people who continued to be exposed to low-level irradiation, the post-transplantation period included a conservative strategy for prevention of graft-versus-host disease. There was nothing unusual about the post-transplantation period, although uncertainty about the continuing radiation dose should be taken into account when interpreting these data.
