Clinical TrialBAVC regimen and autograft for acute myelogenous leukemia in second complete remission.
Since 1984 we have autografted a total of 60 patients with AML in second complete remission (CR) utilizing the BAVC (BCNU, amsacrine, vepesid, cytosine-arabinoside) conditioning regimen and unpurged marrow. Projected disease-free survival (DFS) probability in 42% at 10 years. Autografting was performed at a median interval of 2 months (range 1-13) from second CR. ⋯ A first CR duration > 12 months is correlated with a significantly better overall survival probability (61 vs 25%, P = 0.02), while no factors influence DFS. Outcome of patients who relapsed after autografting has been analyzed separately; a longer overall survival after relapse is correlated with a longer duration of the second CR (62% at 34 months for patients who relapsed after > 12 months from the autograft vs 5% for the others, P = 0.001). These results confirm that AML patients autografted in second CR with BAVC regimen and unpurged marrow have the possibility of becoming long-term DFS and can therefore be cured.

Long-term follow-up of patients undergoing allogeneic bone marrow transplantation for acute myeloid leukemia in first complete remission after cyclophosphamide-total body irradiation and cyclosporine.
Eighty-five patients (median age 28 years) with acute myeloid leukemia (AML) in first remission underwent allogeneic bone marrow transplantation (BMT) from HLA-identical siblings between 1978 and 1987 after cyclophosphamide and single-fraction total body irradiation with cyclosporine for graft-versus-host disease (GVHD) prophylaxis. The actuarial probabilities of development of acute and chronic GVHD were 57% and 47%, respectively. Twenty-six patients died of transplant-related complications at a median of 3.5 months, and two of unrelated causes. ⋯ In multivariate analysis, infusion of a lower cell dose, development of GVHD, and age > 35 years were associated with increased transplant-related mortality, donor-recipient ABO incompatibility with a lower relapse rate, and age > 35 years and a lower cell dose with poorer disease-free survival. We conclude that with long-term follow-up, allografting in AML after cyclophosphamide-TBI and cyclosporine has resulted in disease-free survival that is comparable to most currently reported series. Patients who are alive and well 3-4 years after BMT have excellent prospects of long-term survival.

ReviewAntifungal effects of yeast-derived rhu-GM-CSF in patients receiving high-dose chemotherapy given with or without autologous stem cell transplantation: a retrospective analysis.
Systemic fungal infections (SFI) in patients receiving high-dose chemotherapy (HDC) are a frequent cause of morbidity and mortality. Preclinical studies have reported augmented antifungal activity of monocytes, macrophage cells, and neutrophils exposed to certain colony-stimulating factors (CSF), including GM-CSF. We conducted a retrospective descriptive epidemiologic study to examine the characteristics of 145 consecutive patients receiving HDC administered with or without autologous stem cell transplantation (ASCT) and who subsequently received either GM-CSF and G-CSF, G-CSF alone, GM-CSF +/- IL-3 or no CSF. ⋯ Four SFI-related deaths occurred in the NMMS group and one SFI-related death occurred in the MMS group. Our data suggest a protective role for GM-CSF, IL-3 or other MMS cytokines in preventing SFI in patients receiving HDC. This should be further investigated as a potential complementary approach to conventional strategies in antifungal prophylaxis for patients receiving HDC.

Review Case ReportsSuccessful bone marrow transplantation in a child with X-linked chronic granulomatous disease.
A 16-month-old Aboriginal boy was diagnosed with chronic granulomatous disease (CGD) when he presented with frequent significant infections from the age of 12 months. BMT was performed from a HLA-matched sibling after conditioning with busulphan, cyclophosphamide, etoposide and antithymocyte globulin. A small bowel obstruction developed in the first week and settled with conservative treatment. ⋯ BMT can be successfully performed for CGD. Complications occurring post-BMT may be related to the underlying disease (CGD). BMT remains an attractive option for CGD in children who have a matched sibling donor.

Multicenter StudyAllogeneic peripheral blood progenitor cell transplantation: analysis of short-term engraftment and acute GVHD incidence in 33 cases. allo-PBPCT Spanish Group.
The results of 33 allogeneic peripheral blood progenitor cells transplants (allo-PBPCT) in adult patients with hematologic malignancies were analyzed in a retrospective and multicenter study. In 21 of 33 cases (63%) the disease was refractory or in advanced stage and eight of the 33 cases (24%) were second transplants after relapse. Donors were treated with a median of 10 (4-16) micrograms/kg/day of rhG-CSF subcutaneously for 5-7 days. ⋯ The quantity of CD34+ cells infused did not significantly affect the engraftment kinetics, from a starting cutoff of 2.5 x 10(6)/kg. The speed of neutrophil recovery seemed to be influenced strongly by using rhG-CSF post-transplant and marginally by the type of GVHD prophylaxis. Actuarial probability for grade II-IV acute GVHD of the whole group was 37% (95% Cl, 20-54%).
