Abstract From 1990 to 1993 we performed a prospective study of busulfan (16 mg/kg) and cyclophosphamide (120 mg/kg) in 30 patients with refractory anemia (RA) undergoing related (n = 17) or unrelated (n = 13) donor marrow transplantation. Nineteen patients survive disease free (63% 3-year actuarial disease-free survival [DFS]) and no patient relapsed. These results were compared to those of 38 historical controls with RA treated with cyclophosphamide and total body irradiation, of whom 22 are disease-free survivors and 1 relapsed. After correcting for significant variables between the two treatment groups, we found no statistically significant difference in outcome based on preparative regimen. Combining data from these 68 patients plus 2 additional patients with RA treated before 1993 with busulfan and cyclophosphamide, we identified four variables independently associated with improved survival: younger age, shorter disease duration, lower neutrophil count pretransplant, and lower hematocrit pretransplant. We also found that 15 patients 40 to 55 years of age had a 46% 3-year actuarial DFS and 26 patients receiving unrelated or mismatched related donor marrow had a 50% 3-year actuarial DFS. We conclude that there does not appear to be any significant difference in outcome based on preparative regimen in this patient population. In addition, allogeneic bone marrow transplantation may be a reasonable approach to therapy of RA early after diagnosis. However, whether early intervention with transplantation prolongs survival over that expected without transplantation cannot be ascertained with certainty from available data.

Abstract We treated 93 patients with myelodysplastic syndrome using cyclophosphamide and either total body irradiation (n = 88) or busulfan (n = 5) followed by marrow transplantation. Sixty-five marrow donors were genotypically HLA-identical siblings and 28 were other family members or unrelated donors. Before transplantation all patients had either severe neutropenia or thrombocytopenia or had greater than 5% blasts in the marrow or peripheral blood. The probabilities of disease- free survival, relapse, and non-relapse mortality at 4 years were 41%, 28%, and 43%, respectively. Multivariate analysis revealed that younger age and shorter disease duration were significantly associated with improved disease-free survival and decreased non-relapse mortality. Relapse was seen only in patients with excess blasts at the time of transplantation (51% at 4 years). Patients younger than age 40 and without excess blasts had a 4-year disease-free survival of 62%. This study confirms that allogeneic marrow transplantation can cure some patients with myelodysplasia. Because of the favorable outcome in younger patients without excess blasts, we recommend that transplantation be considered early for patients younger than age 40, before disease progression or development of life-threatening cytopenias. For older patients and those with excess blasts, changes in the transplant procedure will be necessary to improve outcome.

Abstract Seventy patients with acute nonlymphocytic leukemia (ANLL) underwent allogeneic bone marrow transplantation following cytoreduction with total body irradiation and cyclophosphamide. Thirty patients underwent transplantation in first remission, 11 in second remission, 3 in third remission, and 26 in relapse. At a median follow-up of 30 mo, 17 of those in first remission and 7 of those in second remission survive in continuous remission, compared to 1 in third remission and 3 in relapse. The 3-yr Kaplan-Meier probability of disease-free survival among the various groups was 55% (+/- 9.2%) for the first remission transplants, 64% (+/- 14.5%) for second remission, 33% (+/- 20%) in third remission, and 10.3% (+/- 6.3%) in the relapse group. Statistical analysis showed a similar survival in the first and second remission groups that was significantly better than that seen in the third remission and relapse groups (p less than 0.01). The improved survival seen in the early remission groups was due to a significant decrease in the incidence of relapse posttransplant (p less than 0.01). These results confirm observations that a significant number of patients transplanted in first remission may achieve extended disease-free survival and document similar results for patients transplanted in second remission.

Thirty-two children ranging in age from 1.5 to 16 years with poor-prognosis acute lymphoblastic leukemia (ALL) were treated with myeloablative immunosuppressive therapy consisting of cyclophosphamide (CPM) and total body irradiation (TBI) followed by allogeneic bone marrow transplantation (BMT) while in first complete remission (CR). The main reasons for assignment to BMT were WBC count greater than 100,000/microL, structural chromosomal abnormalities, and resistance to initial induction therapy. All children were transplanted with marrow from histocompatible siblings. Twenty-seven patients are alive in first CR for 7 to 82 months post-transplantation (median, 30 months). The actuarial disease-free survival rate is 84.4% (confidence interval, 7.2% to 29%) and the actuarial relapse rate is 3.5% (confidence interval, 0.9% to 13%). Four patients died of transplant-related complications, 16 developed low-grade acute graft-v-host disease (GVHD), and six developed chronic GVHD. The very low incidence of relapse (one of 28 long-term survivors) precluded the determination of the prognostic significance of the different poor-outcome features. Moreover, two infants treated with busulfan, CPM, and cytarabine (Ara-C) relapsed promptly in the marrow. In summary, as a means of providing long-term disease-free survival and possible cure, BMT should be considered for children with ALL presenting poor-prognostic features, particularly certain chromosomal translocations [t(4;11), t(9;22)], very high WBC counts, notably if associated with a non-T immunophenotype, and, perhaps, a poor response to initial therapy with corticosteroids (CS), or infants less than 6 months of age.

Abstract Since the introduction of high-dose cytarabine therapy, there are still controversies for the role of allogeneic or autologous stem cell transplantation (SCT) in acute myeloid leukemia (AML), but the SCT, especially allogeneic, has a benefit in AML patients with intermediate risk. However, it is needed to investigate for a new prognostic factor, in addition to the cytogenetics, to the further stratifying approach. Internal tandem duplications (ITD) within FLT3 are present in 20–30% of patients with AML and have a prognostic implication in the disease. However, there was no report in AML patients who underwent allogeneic bone marrow transplantation (BMT). In this study, we evaluated the prognostic relevance of FLT3/ITD in 42 patients with AML who underwent allogeneic BMT. FLT3/ITD mutations were studied on bone marrow samples at diagnosis using PCR. As a baseline study, we firstly analyzed the incidence of FLT3/ITD in BM samples at diagnosis of 214 patients with AML. Of the patients, FLT3/ITD were found in 68 patients (31.8%). In this study, 64% of the patients who underwent allogeneic BMT were positive for FLT3/ITD mutations. Methologically, FLT3/ITD detections by melting curve analysis showed higher sensitivity (66.7%) than those by gel electrophoresis (61.9%). There were no significant differences in the engraft periods and the incidence of acute and chronic GVHD according to the presence of FLT3/ITD mutations. When we analyze patient’s survival according to the presence or absence of FLT3/ITD, the probability of overall survival (OS) at 3 years in the AML patients with FLT3/ITD tended to be shorter than those lacking FL3/ITD (53.9 ± 9.9% vs. 60.6 ± 14.7%, P=0.46). In addition, the probability of disease free survival (DFS) at 3 years in the AML patients with and without FLT3/ITD was 57.3±10.3% and 85.7±13.2%, respectively (P=0.046). Among the cytogenetic risk group, low-risk and high-risk groups were no significant differences according to FLT3/ITD despite of the limited number of patients studied. However, patients with intermediate-risk were significantly shorter DFS in the presence of FLT3/ITD than those in the absence of FLT3/ITD (P=0.048). These findings suggest that the presence of FLT3/ITD mutations is a poor prognostic factor for disease free survival in AML patients, especially with cytogenetically intermediate-risk, who underwent allogeneic BMT and melting curve analysis to detect the presence of FLT3/ITD mutations is a useful tool with high sensitivity.

Abstract Despite myeloablative and immunosuppressive conditioning therapy, allogeneic bone marrow transplantation (BMT) may fail because of either graft failure or relapse of the malignant disease. In this study we have evaluated the impact of second BMT on long-term disease-free survival (DFS) in 42 patients who were transplanted in our institution between January 1983 and March 2005. GRAFT FAILURE. Eleven patients (4 with aplastic anemia, 4 thalassemia major (TM), 3 chronic myeloid leukemia (CML), 2 acute myeloid leukemia (AML), 1 acute lymphoblastic leukemia (ALL), 1 myelodisplastic syndrome (MDS) received a second BMT for graft failure, either primary (n=8) or secondary (n=3). The median age at time of first BMT was 19 years (range, 3 to 42). The median interval between the first and second BMT was 35 days (range, 27 to 532). Donors were the same of the first BMT. They were HLA genotipically identical (n=8) or HLA phenotipically identical (n=1) or 1 antigen mismatched family members. Four patients died for BMT related causes (2 for acute GvHD, 1 for heart failure and 1 for CNS hemorrhage and rejection). Six patients are now living after a median follow-up of 169 months (range, 52 to 202). Five patients are cured and one had an autologous thalassemia reconstitution and is now living under transfusion treatment. RELAPSE. Thirty-one patients (11 with CML, 9 AML, 9 ALL, 1 MDS, 1 TM) were given a second BMT following relapse of the malignant disease. The median age at time of first BMT was 27 years (range, 1 to 43). The median interval between the first and second BMT was 528 days (range, 115 to 5584 ). Thirty patients received the second BMT from the same HLA genotipically identical family member used for the first transplant. One patient was given the first BMT from a matched unrelated donor and the second transplant from an haploidentical brother. The 6 months transplant related mortality (TRM) was 19%. Six patients died for BMT related causes (4 for acute GvHD, 1 for heart failure and 1 for infection and multiorgan failure). Eight patients had leukaemia relapse following second BMT. Five of them died of chemotherapy complications. One of them, who was reinducted into complete remission and received a third BMT from an unrelated donor, died because encephalopathy. Nineteen patients are living after a median follow-up of 72 months (range, 4 to 236). The 5-years probabilities of overall survival and disease free survival (DFS) were 59% and 52% respectively. The 5-years DFS for AML, CML and ALL patients was 72%, 54% and 12% respectively (p=0.03). The 5-years DFS for 17 patients conditioned with TBI and for 13 patients conditioned with busulphan (BU) was 62% and 31% respectively (p=0.09). This study show that many patients may benefit from a second BMT either following graft failure or leukemia relapse with an acceptable TRM. In particular, patients with AML or CML are the best candidates to be cured from second BMT. TBI conditioning regimen gives better results as compared to BU regimen.
