Abstract Sixty patients undergoing allogeneic bone marrow transplant for acute myeloid leukemia (AML) in first remission (CR1; n = 49) or more advanced phase (n = 11) were entered in a prospective trial of graft-versus-host disease (GvHD) prophylaxis: low-dose cyclosporin A (IdCSA; 1 mg/kg/d from day −1 to +20 day; n = 28) or IdCSA plus low-dose methotrexate (IdMTX; 10 mg/m2 for day +1, 8 mg/m2 for days +3, +6, and +11; n = 32). Primary end points were acute GvHD (aGvHD) and transplant-related mortality (TRM); secondary end points were relapse and survival. The conditioning regimen consisted of cyclophosphamide (120 mg/kg) and fractionated total body irradiation (3.3 Gy/d for 3 consecutive days). The actuarial risk of developing aGvHD grade II-III was 61% for IdCSA alone and 34% for IdCSA + IdMTX (P = .02). The actuarial risk of TRM at 1 year was 11% versus 13%, respectively, and older patients (≧29 years) had higher TRM than younger patients (22% v 5%,P = .01). The age effect was significant in the IdCSA group (P = .04) but not in the IdCSA + IdMTX group (P = .1). The median follow-up is 4.4 years, with an overall actuarial survival of 78% for CR1 patients and 36% for patients with advanced disease. For patients in CR1 the outcome of the two regimens was as follows: survival 77% versus 80% (P = .6), relapse 20% versus 9% (P = .1), and TRM 13% versus 17% (P = .6). This study suggests that TRM can be reduced in AML patients undergoing allogeneic marrow transplants with a mild conditioning regimen and low-dose immunosuppression, and this translates in a 78% 5-year survival for CR1 patients. Beyond CR1 the major obstacle remains leukemia relapse, which is not prevented by low-dose in vivo immunosuppression.

Green tea (GT) treatment was evaluated for its effect on the immune and antineoplastic response of elderly acute myeloid leukemia patients with myelodysplasia-related changes (AML-MRC) who are ineligible for aggressive chemotherapy and bone marrow transplants. The eligible patients enrolled in the study (n = 10) received oral doses of GT extract (1000 mg/day) alone or combined with low-dose cytarabine chemotherapy for at least 6 months and/or until progression. Bone marrow (BM) and peripheral blood (PB) were evaluated monthly. Median survival was increased as compared to the control cohort, though not statistically different. Interestingly, improvements in the immunological profile of patients were found. After 30 days, an activated and cytotoxic phenotype was detected: GT increased total and naïve/effector CD8+ T cells, perforin+/granzyme B+ natural killer cells, monocytes, and classical monocytes with increased reactive oxygen species (ROS) production. A reduction in the immunosuppressive profile was also observed: GT reduced TGF-β and IL-4 expression, and decreased regulatory T cell and CXCR4+ regulatory T cell frequencies. ROS levels and CXCR4 expression were reduced in bone marrow CD34+ cells, as well as nuclear factor erythroid 2–related factor 2 (NRF2) and hypoxia-inducible factor 1α (HIF-1α) expression in biopsies. Immune modulation induced by GT appears to occur, regardless of tumor burden, as soon as 30 days after intake and is maintained for up to 180 days, even in the presence of low-dose chemotherapy. This pilot study highlights that GT extracts are safe and could improve the immune system of elderly AML-MRC patients.

PURPOSE We retrospectively analyzed the outcome of children with acute myeloid leukemia (AML) in first complete remission (CR) who received HLA-identical bone marrow transplantation (BMT) in 13 French transplant centers. PATIENTS AND METHODS Seventy-four children were treated from June 1979 through December 1990. The conditioning regimen included total-body irradiation (TBI) in 54 cases and busulfan in 20. Prophylaxis of graft-versus-host disease (GVHD) consisted of cyclosporine (CycloA) plus methotrexate (MTX) for 38 patients, MTX for 17, CycloA for 18, and T depletion without other prophylaxis for one. The mean value of the interval from diagnosis to transplantation was 167 days. RESULTS Sixteen patients died of transplant-related complications, 12 relapsed, and 46 are alive in continuous remission with a median follow-up of 46 months. We examined results obtained over three successive periods: 1979 to 1982 (n = 14 children), 1983 to 1986 (n = 29), and 1987 to 1990 (n = 31). Probabilities of event-free survival (EFS) were 43%, 48%, and 82% for the three successive periods, respectively (P < .02). This improvement in EFS was linked to a decreased risk of transplant-related mortality: 36%, 36%, and 3%, respectively (P < .01). Other factors associated with a better EFS in the univariate analysis were a short time interval from diagnosis to transplant (< 120 days), the absence of significant (grade > or = 2) acute GVHD, and the absence of chronic GVHD. In the multivariate analysis, two factors had a favorable impact on long-term survival: the year of transplantation (years 1987 to 1990 v others) and the absence of acute GVHD. CONCLUSION The outcome for children receiving allogeneic BMT in first CR of AML has improved in France during recent years.

PURPOSE Childrens Cancer Group (CCG) protocol 2861 was designed to test the feasibility of aggressively timed induction therapy followed by autologous or allogeneic bone marrow transplantation (BMT) as the sole postremission therapy for newly diagnosed children with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). PATIENTS AND METHODS Between April 1988 and October 1989, 142 patients were eligible for study. All patients entered received a timing-intensive five-drug induction of dexamethasone, cytarabine (Ara-C), thioguanine, etoposide, and daunorubicin (DCTER) over 4 days with a second cycle administered after 6 days of rest, irrespective of hematologic status at that time. Most patients subsequently received a second two-cycle induction course. Those who achieved remission were eligible for bone marrow ablative therapy with busulfan and cyclophosphamide, followed by 4-hydroperoxy-cyclophosphamide (4-HC)-purged autologous or allogeneic BMT rescue. RESULTS One hundred eight (76%) patients achieved remission: 19 (13%) died of complications of the leukemia and/or chemotherapy, and 15 (11%) failed to achieve remission. Seventy-four patients subsequently underwent BMT with either autologous (n = 58) or allogeneic (n = 16) rescue. For patients who received autologous rescue with 4-HC-purged grafts, the actuarial disease-free survival (DFS) rate at 3 years from the day of transplant is 51%, compared with 55% for patients who received allogeneic grafts (P = .92). At 3 years, the overall actuarial survival rate for all 142 patients entered on this study is 45%, with an event-free survival (EFS) rate of 37%. Adverse prognostic factors for outcome included an elevated WBC count or the presence of CNS leukemia at the time of AML diagnosis. CONCLUSION Results suggest that aggressively timed induction therapy followed by marrow ablation and BMT rescue with either autologous or allogeneic grafts for children with newly diagnosed AML or MDS is both feasible and effective.

Relapse is a major cause of treatment failure following allogeneic bone marrow transplantation (BMT) for acute myeloid leukemia (AML). To reduce the risk of relapse following BMT for patients with hematologic malignancy, our group developed a novel preparative regimen which combines high-dose etoposide with cyclophosphamide and total body irradiation (VPCyTBI). We now report the outcome of therapy with VPCyTBI followed by allogeneic BMT for 40 patients with AML in untreated first relapse. With the exception of increased stomatitis, the toxicity of this regimen was similar to that reported by others for CyTBI. Forty-four months after transplant the actuarial probabilities of disease-free survival (DFS), persistent or recurrent leukemia, and transplant related mortality were .29, .44, and .47 respectively. DFS was improved (P < .01) and risk of persistent or recurrent leukemia reduced (P = .005) among patients with significant (grade > or = 2) acute GVHD. Patients with 30% or more blasts on pre-BMT bone marrow examination were not at increased risk for persistent or recurrent leukemia. We conclude that VPCyTBI with allogeneic BMT is effective therapy for AML in untreated first relapse and that a randomized trial comparing this regimen with CyTBI is warranted.
