The impact of the graft-versus-leukemia effect on survival in acute lymphoblastic leukemia. Blood Adv 2020; 3:670-680. [PMID: 30808685 DOI: 10.1182/bloodadvances.2018027003] [Citation(s) in RCA: 54] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Accepted: 01/22/2019] [Indexed: 11/20/2022] Open
Abstract
Allogeneic hematopoietic cell transplant is a potential curative therapy for acute lymphoblastic leukemia (ALL). Delineating the graft-versus-leukemia (GVL) effect as a function of graft-versus-host disease (GVHD) offers the potential to improve survival. We examined 5215 transplant recipients with ALL reported to the Center for International Blood and Marrow Transplant Research registry. Overall survival (OS) was compared according to the presence and severity of GVHD and evaluated in 3 cohorts: 2593 adults in first or second complete remission (CR1/CR2), 1619 pediatric patients in CR1/CR2, and 1003 patients with advanced (CR ≥3 or active disease) ALL. For patients in CR1/CR2, development of acute GVHD (aGVHD) or chronic GVHD (cGVHD) was associated with lower risk of relapse than no GVHD (hazard ratio [HR], 0.49-0.69). Patients with advanced ALL developing grades III and IV aGVHD or cGVHD were also at lower risk of relapse (HRs varied from 0.52 to 0.67). Importantly, adult and children in CR1/CR2 with grades I and II aGVHD without cGVHD experienced the best OS compared with no GVHD (reduction of mortality with HR, 0.83-0.76). Increased nonrelapse mortality accompanied grades III and IV aGVHD (HRs varied from 2.69 to 3.91) in all 3 cohorts and abrogated any protection from relapse, resulting in inferior OS. Patients with advanced ALL had better OS (reduction in mortality; HR, 0.69-0.73) when they developed cGVHD with or without grades I and II aGVHD. In conclusion, GVHD was associated with an increased GVL effect in ALL. GVL exerted a net beneficial effect on OS only if associated with low-grade aGVHD in CR1/CR2 or with cGVHD in advanced ALL.

Total Body Irradiation without Chemotherapy as Conditioning for an Allogeneic Hematopoietic Cell Transplantation for Adult Acute Myeloid Leukemia. Case Rep Hematol 2016; 2016:1257679.

Abstract
Current therapies for acute myeloid leukemia (AML), failing induction, are rarely effective. We report our experience in 4 patients with AML who received 16 Gy TBI prior to allogeneic hematopoietic cell transplantation (alloHCT), between June 2010 and May 2011. Patients were 20 to 55 years of age, 2 with relapsed disease and 2 with AML failing induction. An HLA-matched graft from related or unrelated donor was infused on day 0. All but one, who received a CD34+-selected graft, received methotrexate and tacrolimus +/- antithymocyte globulin, as GVHD prophylaxis. The other patient received tacrolimus alone. Neutrophil and platelet engraftment occurred at a median of 18 and 14 days, respectively. Patients were discharged at a median of 28 days. There were no unexpected toxicities in the first 30 days. One patient had cytomegalovirus (CMV) viremia and anorexia, at two months. One patient had grade 2 acute GVHD of the skin. One patient developed chronic GVHD of the eyes, mouth, skin, joints, and lung at 4 months. Two patients died from relapse of their leukemia at days 65 and 125. Two patients remain in remission beyond day 1500. 16 Gy TBI followed by an alloHCT for AML, failing induction, is feasible and tolerable.

A multicenter trial of myeloablative clofarabine and busulfan conditioning for relapsed or primary induction failure AML not in remission at the time of allogeneic hematopoietic stem cell transplantation. Bone Marrow Transplant 2016; 52:59-65. [PMID: 27427921 DOI: 10.1038/bmt.2016.188] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2016] [Revised: 05/30/2016] [Accepted: 05/31/2016] [Indexed: 11/09/2022]
Abstract
Allogeneic hematopoietic cell transplantation (HCT) may produce long-term survival in AML after relapse or primary induction failure (PIF). However, outcomes of HCT performed for AML not in remission are historically poor given high relapse rates and transplant-related mortality. Preliminary studies suggest conditioning with clofarabine and myeloablative busulfan (CloBu4) may exert significant anti-leukemic effects without excessive toxicity in refractory hematologic malignancies. A prospective multicenter phase II trial was conducted to determine the efficacy of CloBu4 for patients proceeding directly to HCT with AML not in remission. Seventy-one patients (median age: 56 years) received CloBu4. At day 30 after HCT, 90% achieved morphologic remission. The incidence of non-relapse mortality and relapse at 2 years was 25% and 55%, respectively. The 2-year overall survival (OS) and event-free survival (EFS) were 26% and 20%, respectively. Patients entering HCT in PIF had significantly greater EFS than those in relapse (34% vs 8%; P<0.01). Multivariate analysis comparing CloBu4 with a contemporaneous cohort (Center for International Blood and Marrow Transplantation Research) of AML not in remission receiving other myeloablative conditioning (n=105) demonstrated similar OS (HR: 1.33, 95% confidence interval: 0.92-1.92; P=0.12). HCT with myeloablative CloBu4 is associated with high early response rates and may produce durable remissions in select patients with AML not in remission.

Abstract
Purpose The purpose of this study was to compare leukemia-free survival (LFS) and other clinical outcomes in patients with acute myelogenous leukemia who underwent a myeloablative allogeneic stem cell transplant with and without total body irradiation (TBI). Methods and materials Adult patients with acute myelogenous leukemia undergoing myeloablative allogeneic stem cell transplant at Duke University Medical Center between 1995 and 2012 were included. The primary endpoint was LFS. Secondary outcomes included overall survival (OS), nonrelapse mortality, and the risk of pulmonary toxicity. Kaplan-Meier survival estimates and Cox proportional hazards multivariate analyses were performed. Results A total of 206 patients were evaluated: 90 received TBI-based conditioning regimens and 116 received chemotherapy alone. Median follow-up was 36 months. For all patients, 2-year LFS and OS were 36% (95% confidence interval [CI], 29-43) and 39% (95% CI, 32-46), respectively. After adjusting for known prognostic factors using a multivariate analysis, TBI was associated with improved LFS (hazard ratio: 0.63; 95% CI: 0.44-0.91) and OS (hazard ratio: 0.63; 95% CI, 0.43-0.91). There was no difference in nonrelapse mortality between cohorts, but pulmonary toxicity was significantly more common with TBI (2-year incidence 42% vs 12%, P < .001). High-grade pulmonary toxicity predominated with both conditioning strategies (70% and 93% of cases were grade 3-5 with TBI and chemotherapy alone, respectively). Conclusions TBI-based regimens were associated with superior LFS and OS but at the cost of increased pulmonary toxicity.

Abstract
To further find effective method to improve the long term survival of refractory or relapsed acute myeloid leukemia (AML) patients, we retrospectively analyzed the outcomes of myeloablative hematopoietic stem cell transplantation (HSCT) for 133 consecutive patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) therapy related AML(t-AML) in not remission status. The overall 3-year OS and DFS were 40.9% and 35.6% respectively. The variables associated with improved long term DFS were a bone marrow blast cell count less than 20% and an intensified conditioning regimen. In addition, the t-AML group had higher rates of relapse and III-IV acute GVHD than the primary AML group. The unrelated donor group had similar OS and DFS with sibling groups. Our study suggested that decreasing bone marrow blast cell counts before HSCT and strengthening the conditioning regimen may improve long-term DFS for refractory/relapsed AML patients, and unrelated donor group can get similar effect when compared to the sibling group.

High-dose cytarabine as salvage therapy for relapsed or refractory acute myeloid leukemia--is more better or more of the same? Hematol Oncol 2015; 34:28-35.

Abstract
Cytarabine is the backbone of most chemotherapeutic regimens for acute myeloid leukemia (AML), yet the optimal dose for salvage therapy of refractory or relapsed AML (RR-AML) has not been established. Very high dose single-agent cytarabine at 36 g/m(2) (ARA-36) was previously shown to be effective and tolerable in RR-AML. In this retrospective analysis, we aim to describe the toxicity and efficacy of ARA-36 as salvage therapy for patients with AML who are primary refractory to intensive daunorubicin-containing induction or those relapsing after allogeneic stem cell transplant (alloSCT). Fifteen patients, median age 53 years, were included in the analysis. Six patients were treated for induction failure, one had resistant APL, and eight relapsed after alloSCT. Complete remission was achieved in 60% of patients. Surviving patients were followed for a median of 8.5 months. One-year overall survival was 54% (95% CI 30%-86%), and relapse rate from remission (n = 9) was 56%. Grade III/IV pulmonary, infectious, ocular and gastrointestinal toxicities occurred in 26%, 20%, 20% and 20% of patients respectively. Salvage therapy with ARA-36 regimen for RR-AML has considerable efficacy with manageable toxicity in patients with induction failure or post-transplant relapse. Overall survival in these high-risk patients still remains poor.

Abstract
Internal tandem duplication of the fms-like tyrosine kinase-3 gene (FLT3-ITD) and nucleophosmin-1 (NPM1) mutations have prognostic importance in acute myeloid leukemia (AML) patients with intermediate-risk karyotype at diagnosis, but less is known about their utility to predict outcomes at relapse. We retrospectively analysed outcomes of 70 patients with relapsed, intermediate-risk karyotype AML who received a uniform reinduction regimen, with respect to FLT3-ITD and NPM1 mutation status and first complete remission (CR1) duration. CR1 duration, but not molecular status, was significantly correlated with CR2 rate. On univariate analysis, patients with mutated FLT3-ITD (FLT3+) had significantly worse overall survival (OS) compared with those with neither an NPM1 nor FLT3-ITD mutation (NPM1-/FLT3-). On multivariate analysis, shorter CR1 duration was significantly correlated with inferior OS at relapse (P<0.0001), while FLT3 and NPM1 mutation status and age were not significantly correlated with OS. Patients who subsequently underwent allogeneic stem cell transplant (alloSCT) had a superior OS regardless of CR1 duration, but outcomes were better in patients with CR1 duration>12 months. In intermediate-risk karyotype AML patients receiving reinduction, CR1 duration remains the most important predictor of OS at relapse; FLT3-ITD and NPM1 status are not independent predictors of survival.

Abstract
Clofarabine and gemtuzumab ozogamicin (GO) are active agents against acute myeloid leukemia (AML), but have not previously been tested in combination. We conducted a phase I study to determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLTs) of clofarabine when combined with GO in adult patients with relapsed or refractory AML. Twenty patients received clofarabine (10, 20 or 30 mg/m(2)) on days 1-5, with GO 3 mg/m(2)/day on days 1, 4 and 7. Common dose-limiting toxicities were prolonged myelosuppression and hepatotoxicity. Clofarabine 20 mg/m(2) was the MTD, but with a DLT rate of 0.38 (5/13) - a rate that is prohibitively high to recommend for phase II study. The overall response rate (complete response [CR] + complete response with incomplete hematologic recovery [CRi]) was 42% among all patients. Thus, this combination demonstrated activity in relapsed and refractory patients, but further testing of the combination using lower doses of GO may identify more favorable rates of toxicity while maintaining efficacy.

Abstract
We conducted a phase I trial to determine the maximum tolerated dose (MTD) of clofarabine with high-dose busulfan followed by allogeneic stem cell transplantation (SCT) in patients with high-risk and refractory acute leukemia. Patients received intravenous busulfan 0.8 mg/kg every 6 h on days -6 to -3 and clofarabine 30-60 mg/m(2) per day on days -6 to -2. Graft-versus-host disease prophylaxis included sirolimus plus tacrolimus (days -2 to +180). A total of 15 patients, median age 48 (30-58) years, with acute leukemia that was relapsed and refractory (n=8), primary refractory (n=6), or in CR2 (n=1), were treated at four clofarabine dose levels: 30 (n=3), 40 (n=3), 50 (n=3) and 60 mg/m(2) per day (n=6) with busulfan. All engrafted, and the MTD was not reached. Grades 3-4 non-hematological toxicities included vomiting (n=3), mucositis (n=9), hand-foot syndrome (n=1), acute renal failure (n=1) and reversible elevation of aspartate aminotransferase/alanine aminotransferase (n=10). The 1-year event-free survival was 53% (95% confidence interval: 33-86%), and the 1-year overall survival was 60% (95% confidence interval: 40-91%). Given the good tolerability and promising results, we recommend clofarabine 60 mg/m(2) per day × 5 days as a phase II dose in combination with busulfan (12.8 mg per kg total dose) for further study as a myeloablative regimen for allogeneic SCT for high-risk acute leukemia.

Abstract
Adults with high-risk acute lymphoblastic leukemia (HR-ALL) have a poor outcome with standard chemotherapy and usually undergo unrelated stem cell transplantation (SCT) if a matched sibling donor is not available. We analyzed the outcome of adult patients with unrelated SCT for HR-ALL and studied the possible effect of the hematopoietic stem cell source of the transplant. A total of 149 adult patients (median age, 29 years, range, 15-59 years) with HR-ALL underwent unrelated SCT in 13 Spanish institutions between 2000 and 2007. Patients in first complete remission (CR1) at transplantation had at least one adverse prognostic factor (advanced age, adverse cytogenetics, hyperleukocytosis, or slow response to induction therapy). ALL was in CR1 in 81 patients (54%), in second CR (CR2) in 37 patients (25%), in third CR (CR3) in 11 patients (7%), and with overt disease in 20 patients (13%). The hematopoietic source was unrelated cord blood (UCB) in 62 patients and an unrelated donor (UD) in 87 patients. The patients undergoing UCB-SCT and UD-SCT were comparable in terms of the main clinical and biological features of ALL, except for a higher frequency of patients with more overt disease in the UCB-SCT group. There was no statistically significant difference in overall survival (OS) or disease-free survival (DFS) at 5 years between the 2 groups. Treatment-related mortality (TRM) was significantly lower in the UCB-SCT group (P = .021). The probability of relapse at 1 year was 17% (95% confidence interval [CI], 7%-27%) for the UD-SCT group and 27% (95% CI, 14%-40%) for the UCB-SCT group (P = .088), respectively. Only disease status at transplantation (CR1, 41% [95% CI, 18%-64%] vs CR2, 51% [95% CI, 17%-85%] vs advanced disease, 66% [95% CI, 46%-86%]; P = .001) and the absence of chronic graft-versus-host disease (74% [95% CI, 46%-100%] vs 33% [95% CI, 17%-49%]; P = .034) were significant factors for relapse. All unrelated transplantation modalities were associated with high treatment-related mortality for adult HR-ALL patients without a sibling donor. UCB-SCT and UD-SCT were found to be equivalent options. Disease status at transplantation and chronic GVHD were the main factors influencing relapse in both transplantation modalities.

Abstract
The Philadelphia (Ph) chromosome, a short chromosome 22, is the most frequent cytogenetic abnormality in adult patients with acute lymphoblastic leukemia (ALL). It occurs in approximately 20% to 30% of adults and in about 5% of children with this disease. The incidence rises with age and occurs in approximately 50% of patients older than 50 years. This article reviews the treatment regimens for Ph+ ALL, including imatinib and second generation tyrosine kinase inhibitors (TKIs). The introduction of effective TKIs in the treatment of Ph+ ALL has introduced several avenues of research in a disease that was hitherto difficult to treat.

Abstract
Aim: To analyze the results of idarubicin (IDA)- versus etoposide (VP16)-intensified myeloablative conditioning regimen in allogeneic hematopoietic stem cell transplantation (allo-SCT) for high-risk acute leukemia. Methods: From January 2005 to June 2008, 48 consecutive patients (male: n=29; median age: 30 years, range 14–51 years) with high-risk acute leukemia underwent allo-SCT following an IDA- or VP16-intensified conditioning regimen. The conditioning regimens were modified BUCY2 (busulfan+cyclophosphamide) consisting of IDA (15 mg/m2 per day, days -12 to -10) or VP16 (25 mg/kg per day, days -3 to -2) and CY/TBI (cyclophosphamide/total body irradiation) intensified with IDA (15 mg/m2 per day, days -6 to -5) or VP16 (25 mg/kg per day, days -3 to -2) for acute myeloid leukemia and acute lymphoblastic leukemia, respectively. Results: Between the two groups, no significant differences in terms of baseline characteristics, incidence of acute or chronic graft-versus-host disease (GVHD) or transplant-related mortality (TRM) (P=0.50) were observed. However, the IDA group demonstrated higher incidences of mucositis and Aspergillus pneumonia (P<0.01 and P=0.03, respectively). For the IDA and VP16 groups, relapse rates were 28% and 50%, respectively (P=0.13). For the same groups, the 2-year probabilities of leukemia-free survival (LFS) and overall survival (OS) were 72% versus 51% (P=0.04) and 74% versus 53% (P=0.04), respectively. Conclusion: This retrospective analysis suggests that conditioning regimens intensified with IDA can achieve better outcomes than conditioning regimens with VP16 in patients preparing to undergo allo-SCT for high-risk acute leukemia.

Abstract
The role of autologous or allogeneic hematopoietic stem cell transplantation (HSCT) in ALL is controversial because of its adverse risk/benefit ratio, and the main policy is to reserve it for high-risk patients. In our Institution, between 1984 and 2002, 40 patients received an allogeneic HSCT and 39 underwent autografting. The conditioning regimen included HD-Ara-C, HD-CTX and 10 Gy fractionated TBI. After allogeneic SCT in first CR, four patients relapsed, leading to a 10-year EFS chance of 78.3%; of the other patients, 5 are still in CR. After autografting in first CR, there was an early death, one secondary AML, one death in CR and six relapses, leading to a 10-year EFS chance of 44.4%; of the other patients, 6 are still in CR. Even considering the limited number of patients and the slow accrual rate, selection bias cannot be considered a sufficient explanation for the favorable outcome of allografting in first CR as the majority of the patients had adverse prognostic factors. It cannot be claimed that allogeneic SCT was performed in patients already cured, as the autografted patients had a notably worse outcome, and a 10-year EFS chance of about 80% is an uncommon finding even in standard-risk ALL patients. It might be inferred that the timing of SCT as late intensification, in addition to a rather aggressive conditioning regimen, helped to minimize the leukemic burden, thus favoring the expression of a GVL effect. Conversely, the results in more advanced disease phases are discouraging, due to poor quality CRs and inefficacy of GVL in managing large residual disease.

Abstract
Post-remission options were compared in a population of 262 relapsing and refractory acute myeloid leukemia patients achieving complete remission (CR) after the same re-induction according to etoposide - mitoxantrone - cytarabine (EMA) trials. The selection of post-remission therapy depended on trial recommendations, age, performance status, and availability of an HLA-identical sibling. One hundred and thirty patients received chemotherapy consolidation courses, 50 received autologous stem cell transplantation (SCT), and 43 underwent allogeneic bone marrow transplantation (BMT), while 39 did not receive any additional therapy. The preliminary analysis identified 3 favorable prognostic factors correlated with event-free survival (EFS): M3 subtype, previous CR duration > 1 year, and transplantation. Three year EFS was 68 vs. 23% with autologous SCT and allogeneic BMT in M3 patients and, respectively, 41 vs. 20% in non-M3 patients. Three year probabilities of treatment-related mortality were 11 and 47%, respectively. A statistical model was conceived with adjustment on prognostic factors and post-remission option. In the multivariate analysis, autologous SCT appeared significantly better than allogeneic BMT (P < 0.01) or chemotherapy (P = 0.001), while allogeneic BMT was not statistically different than chemotherapy. This indicates a high treatment-related toxicity with allogeneic BMT in patients re-induced by highly intensive chemotherapy, and therefore a tendency for a better outcome with autologous SCT as post-remission treatment in those patients.

Abstract
Acute myeloid leukemia (AML) is a heterogeneous disease with outcomes dependent upon several factors, including patient age, karyotype, mutational status, and comorbid conditions. For younger patients, approximately 60% to 80% achieve complete remission with standard therapy involving cytarabine and an anthracycline. However, only 20% to 30% have long-term disease-free survival. For adults older than 60 years of age, only 40% to 55% achieve a complete remission, with dismal long-term survival rates. Unfortunately, the median age at diagnosis for AML is 70 years. Significant advances in our understanding of the molecular biology of AML have led to newer therapies that specifically target molecular abnormalities. Examples of such therapies include the immunoconjugate gemtuzumab ozogamicin, FMS-like tyrosine kinase 3 inhibitors, farnesyl transferase inhibitors, histone deacetylase inhibitors, DNA hypomethylating agents, multidrug-resistance inhibitors, BCL-2 inhibitors, antiangiogenesis agents, and various nucleoside analogs. This review summarizes the standard treatments for AML and discusses the role of novel therapies.

Abstract
We present 60 patients with refractory (n=8) or relapsed (n=52) adult ALL who received allogeneic hematopoietic SCT (HSCT) with (n=41) or without (n=19) prior reinduction chemotherapy. In our center, omission of reinduction is recommended if a suitable donor is promptly available, tumor burden is moderate and disease features suggest a highly aggressive course. Overall survival (OS) of the whole cohort at 1, 2 and 5 years was 42, 33 and 28%, respectively. Leukemia-free survival at 1, 2 and 5 years was 37, 33 and 24%. Deaths were due to relapse (n=25), acute or chronic GVHD (n=7), infections (n=8) or toxicity (n=4). Interestingly, patients who did not receive reinduction before HSCT had better outcomes than patients who received reinduction with OS at 1, 2 and 5 years being 58 vs 34%, 47 vs 25% and 47 vs 18%, respectively (P=0.039). Importantly, even achievement of a second CR after reinduction was not associated with improved survival compared to patients directly proceeding to HSCT. We conclude that patients who undergo HSCT for refractory or relapsed ALL can achieve long-term survival. In selected patients, reinduction chemotherapy can be omitted if immediate HSCT is feasible.

Abstract
Disease recurrence has been and remains the leading cause of treatment failure in patients with high-risk leukemia. We retrospectively analyzed outcome in 61 patients with high-risk leukemia receiving a combination of fludarabine and intermediate-dose cytarabine as induction (n = 11) or salvage therapy (n = 35). Thirty-six patients having a suitable stem cell donor proceeded to allogeneic hematopoietic stem cell transplantation (HSCT). Ten patients received fludarabine-based salvage therapy without consecutive allogeneic transplantation and 15 patients received fludarabine/intermediate-dose cytarabine because of disease relapse following allogeneic stem cell transplantation. In patients without prior allogeneic HSCT (n = 46) the complete remission rate (CR) was 41% with a CR rate of 46 and 14% in patients with acute myeloid leukemia (AML) and with acute lymphoblastic leukemia (ALL), respectively. Overall survival for patients achieving a CR was 41 versus 0% for patients not achieving CR (P < 0.0001). The best outcome was observed in patients receiving an allogeneic HSCT in CR following fludarabine/ intermediate-dose cytarabine (47 vs. 0% for patients not in CR at the time of allografting, P = 0.01). All 10 patients receiving fludarabine/intermediate-dose cytarabine without subsequent allogeneic HSCT died within 3 years either of disease relapse/progression or infection. Only 1/15 (7%) patients receiving fludarabine/intermediate-dose cytarabine because of relapse following allogeneic HSCT became a long-term survivor. By multivariate analysis achieving CR, receiving an allogeneic HSCT, and being in first relapse or untreated were the only parameters that significantly determine the outcome. Although preliminary only high-risk AML patients having a stem cell donor are candidates for fludarabine/intermediate-dose cytarabine and only those achieving a CR should be referred to subsequent allogeneic HSCT. All other patients with high-risk leukemia are candidates for experimental therapies within controlled trials.

Abstract
The aim of the present study was to identify graft-versus-leukemia effects and the factors that affect outcome in 201 adults with acute lymphobalstic leukemia who received myeloablative allogeneic stem cell transplantation from matched sibling or unrelated donors (1995-2004). One hundred seventy-eight (88.6%) of these patients had high-risk criteria, and 151 (75.1%) patients were transplanted in first complete remission (CR). All patients received unmodified stem cell grafts (185 bone marrow and 16 peripheral blood) following total- body irradiation-containing myeloablative preparations. Graft-versus-host disease (GVHD) prophylaxis was uniformly attempted by administering calcineurin inhibitor plus methotrexate. After a median follow-up of 63 months (range: 25+ to 139+ months) for surviving transplants, disease-free survival at 5 years was 47.8% for all patients and 60.3% for patients in the first CR. No difference in transplantation outcome was observed between sibling and unrelated transplants in the first CR. The most powerful predictive factor affecting transplantation outcome was disease status at transplantation (the first CR versus beyond the first CR, P<.001). Chronic GVHD (cGVHD), especially limited type, was also found to have a significant antileukemic effect. Interestingly, the influence of cGVHD on relapse risk was prominent in patients with chromosomal translocations or normal cytogenetics.

Abstract
Prognostic factors for survival following allogeneic BMT for AML include age, disease status and cytogenetic risk classification. Lactate dehydrogenase (LDH) levels have not been studied as a potential risk factor. We reviewed our experience with BMT for AML and included LDH at the time of admission in an analysis of prognostic factors for survival. We found that LDH >330 U/l (1.5 times the upper limit of normal at our institution), older age, active disease, peripheral stem cell graft and male-to-male transplant were significant adverse predictors of survival. After accounting for LDH, other factors such as disease status and cytogenetics were not significantly associated with the outcome of BMT. All but one patient with an LDH >330 U/l had active disease. However, when patients in CR were excluded, LDH >330 U/l remained a significant adverse predictor of overall survival (hazard ratio 2.70, 95% confidence interval 1.41-5.16, P=0.003). We conclude that LDH is an important adverse risk factor for survival and should be included in future studies of risk performed on larger patient cohorts.

Abstract
This chapter addresses the impact of the disease and disease status on the outcome of stem-cell transplantation. In consideration of the other topics addressed within this volume we have elected to focus on allogeneic rather than autologous transplantation. Furthermore we have not tried to be comprehensive and discuss the role of disease status in all conditions amenable to allografting, but rather to review the evidence that exists for selected haematological malignancies. Where possible we have made some clear recommendations, but where evidence is less clear we have indicated the ongoing controversies.

Abstract
Outcome of adults with acute lymphoblastic leukemia (ALL) who fail to achieve complete remission (CR) or who relapse soon after initial response is poor. The goal of this phase II study by the Polish Adult Leukemia Group (PALG) was to evaluate safety and efficacy of a new salvage regimen (FLAM) consisting of sequential fludarabine, cytarabine, and mitoxantrone. Fifty patients were included with primary (n = 13) or secondary (n = 5) refractoriness, early (<12 months) first relapse (n = 15), first relapse after hematopoietic cell transplantation (HCT) regardless CR duration (n = 13), and second or subsequent relapse (n = 4). Median age was 31(18-60) years, 28% of patients were bcr/abl-positive. CR rate equaled 50% and was significantly higher for patients in whom FLAM was administered as a second-line therapy compared to those more heavily pre-treated (66 vs 13%, p = 0.02). Seventeen patients had leukemia regrowth after initial cytoreduction, whereas, eight patients died in aplasia. The incidence of early death was higher in patients aged > or =40 years compared to the younger subgroup (33 vs 8%, p=0.03). Septic infections were the most frequent severe complication. At 3 years, the probability of disease-free survival for patients who achieved CR equaled 16%. Seven patients underwent allogeneic HCT. FLAM regimen is feasible for relapsed and refractory adults with ALL and could be recommended in particular for younger patients as a second-line treatment. However, as the remission duration is short, allogeneic HCT (alloHCT) should be considered as soon as possible.

Abstract
We report the results of 84 patients with ALL after related (n = 46) or unrelated (n = 38) allogeneic SCT. Mean recipient age was 23 years (range: 1-60) and median follow-up was 18 months (range: 1-133). Forty-three patients were transplanted in CR1; 25 in CR2 or CR3; four were primary refractory; four in PR; eight in relapse. The conditioning regimen consisted of TBI/VP16/CY (n = 76), TBI/VP16 (n = 2), TBI/CY (n = 2), Bu/VP16/CY (n = 4). The OS at 3 years was 45% (44% unrelated, 46% related). Univariate analysis showed a significantly better OS for patients <18 years (P=0.03), mismatched sex-combination (P = 0.03), both with a stronger effect on increasing OS after unrelated SCT. Factors decreasing TRM were patient age <18 years (P = 0.004), patient CMV-seronegativity (P = 0.014), female recipient (P = 0.04). There was no significant difference in TRM and the relapse rate was similar in both donor type groups. Multivariate analysis showed that factors for increased OS which remained significant were mismatched sex-combination (RR: 0.70,95% CI: 0.51-0.93, P = 0.015), patient age < 18 years (RR: 0.66, 95% CI: 0.47-0.93, P = 0.016). A decreased TRM was found for female patients (RR: 0.56, 95% CI: 0.33-0.98, P=0.042), negative CMV status of the patient (RR: 0.57, 95% CI: 0.36-0.90, P = 0.015). Unrelated stem cell transplantation for high-risk ALL patients with no HLA-compatible family donor is justifiable.

Abstract
We examined retrospectively 44 patients with refractory acute leukemia (acute myeloid leukemia (AML)/acute lymphoblastic leukemia=25/19) who underwent allogeneic transplantation at our center between 11/1990 and 04/2004. The median leukemic blasts was 25% and age 28 years (range, 3-56). Twenty-one patients had untreated relapse, 13 failed reinduction, eight in partial remission and two aplastic. Conditioning was myeloablative using cyclophosphamide, busulfan, total-body irradiation and etoposide (Bu/Cy/VP, n=22; TBI/Cy/VP, n=17; others, n=5) followed by marrow or peripheral blood transplant (n=23/21) from unrelated or related donors (n=28/16). All patients had graft-versus-host disease (GVHD) prophylaxis with cyclosporin and methotrexate. One patient experienced late graft failure. Severe acute-GVHD and chronic-GVHD appeared in eight and 14 patients, respectively. Thirteen patients (30%) remain alive after a median of 25.3 months (range, 2.4-134.1); with 31 deaths, mostly from relapse (n=15) and infections (n=12). Overall survival (OS) and progression-free survival (PFS) at 5 years was 28 and 26%, respectively. OS and PFS were significantly better with blasts < or =20% and time to transplant < or =1 year while transplant-related mortality was less with the use of TBI. We conclude that patients with refractory leukemia can benefit from allogeneic BMT, especially with < or =20% marrow blast.

Abstract
Although continued advances have been made in the treatment of acute myeloid leukemia (AML), approximately 20-30% of patients will never achieve a remission. For these patients with primary refractory AML, the only curative option remains an allogeneic stem cell transplant. Allogeneic transplantation provides the ability to administer myeloablative doses of chemotherapy or chemoradiotherapy, as well as the advantage of a possible graft-versus-leukemia effect. Difficulty in interpreting the literature is due to selection bias, in particular, the varying definitions of primary refractory disease with respect to the morphological criteria and the number of induction regimen required before being defined as being refractory. Regardless, it is a procedure with high treatment-related mortality and risk of relapse. Most studies demonstrate an event-free survival of 10-20% at 5 years. Predictive factors of outcome include blast cell count in the marrow, karyotype, the number of prior regimen, age, performance status and availability of a related donor. These prognostic factors should be considered prior to offering allogeneic transplantation for primary refractory AML. Those patients with many favorable prognostic factors and an HLA-matched related donor available would be the best candidate for the procedure. Those with many poor prognostic factors and only an unrelated donor available may be better served by being offered palliation or being enrolled in investigational studies.

Abstract
Previously, we suggested that imatinib incorporation into conventional chemotherapy as an alternative (imatinib interim therapy) might be a useful strategy for bridging the time to allogeneic stem cell transplantation (SCT) for newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+) ALL). Here, we provide an updated report on this strategy in 29 patients. At the time of enrollment, 23 patients (79.3%) achieved complete remission (CR). After the first imatinib cycle, the median breakpoint cluster region-Abelson oncogene locus (BCR-ABL)/ABL ratios decreased by 0.77 log in 25 (86.2%) responders, and their BCR-ABL/ABL ratios decreased further by 0.34 log after the second imatinib cycle, which included 7 molecular CR. One patient (4.3%) relapsed during the imatinib therapy. The remaining 3 patients were primarily refractory to both imatinib and chemotherapy. Twenty-five (86.2%) of the 29 patients received transplants in first CR. With a median follow-up duration of 25 months after SCT, the 3-year estimated probabilities of relapse, nonrelapse mortality, disease-free survival, and overall survival were 3.8%, 18.7%, 78.1%, and 78.1%, respectively. In comparison to our historical control data, first-line imatinib interim therapy appears to provide a good quality of CR and a survival advantage for patients with Ph(+) ALL. Further long-term follow-up is needed to validate the results of this study.

Abstract
Deficiencies or structural defects of the apoptotic machinery have been postulated as a potential mechanism for a broad resistance of acute myeloid leukaemia (AML) blasts towards cytotoxic therapy comprising chemotherapeutic agents with diverse pharmacodynamic principles but also cell-mediated cytotoxicity of the graft-versus-leukaemia effect, for example, in the setting of allogeneic transplantation. This hypothesis was systematically tested by functionally analysing the early, intermediate and late events of the apoptotic process in primary AML (n = 31) blasts following activation of the intrinsic and extrinsic pathway of apoptosis (etoposide and cytarabine as DNA damaging agents, FAS-ligand as an activator of the death receptor pathway). Activation of the extrinsic pathway by FAS-ligand did not induce apoptosis in primary AML, instead the proapoptotic signal was shown to 'fade', even in the early phase of the apoptotic sequence. However, activation of the intrinsic pathway induced severe cytotoxicity in all samples that showed the characteristic features of typical apoptosis, with a prominent apoptotic volume decrease (blebbing) in the early phase, significant increases in caspase 3 activity (intermediate or effector phase) and breakdown of cellular energy production in the late phase of apoptosis. These characteristics did not differ between prognostically favourable versus unfavourable AML karyotypes or between clinically responding versus refractory AML--indicating that a functional apoptotic apparatus is present even in the unfavourable AML subgroups. Our data indicate that the mechanism for a broad clinical resistance is not a dysfunctional apparatus per se but rather the consequence of anti-apoptotic regulation impeding otherwise functional apoptotic machinery.

Abstract
Acute graft-versus-host disease (GVHD) increases post-transplant mortality and morbidity, but exerts a potent graft-versus-leukemia (GVL) effect. To clarify the impact of GVHD on outcome after transplant in aggressive diseases, patients with acute myeloid or lymphoblastic leukemia (AML, n = 366 or ALL, n = 255) in nonremission states, or chronic myelogenous leukemia (CML, n = 180) in accelerated phase (AP) or blastic crisis (BC), who received allogeneic hematopoietic stem cell transplantation (HSCT) from a related donor between 1991 and 2000, were analyzed. Significant improvement in overall and disease-free survival (DFS) was detected with grade I acute GVHD in AML (P = 0.0002 for overall survival and 0.0009 for DFS, respectively) and in CML (P = 0.0256 and 0.0366, respectively), while the trend towards improved survival was observed in ALL. Relapse rate was lower in grade I acute GVHD than in grade II in all three diseases, suggesting that treatment for grade II GVHD may compromise the GVL effect associated with GVHD. Chronic GVHD was found to suppress relapse in CML and ALL, but not in AML, although no improvement in survival was observed in any disease category. Our results suggest that treatment for grade II acute GVHD may need to be attenuated in transplant for refractory leukemias.

Abstract
The diverse clinical applications of allogeneic peripheral blood stem cells based on use of their advantages are summarized. It is apparent that more stem cells and T-lymphocytes can be harvested by mobilization treatment with cytokines from healthy donors in allogeneic peripheral blood stem cell transplantation (PBSCT) than in bone marrow transplantation. It is also clear that a stronger graft-versus-tumor effect can be induced with allogeneic PBSCT than with bone marrow transplantation. One merit of allogeneic PBSCT is that it allows clinicians to design diverse clinical applications. It would appear that allogeneic PBSCT may be preferable in special clinical settings, such as advanced hematological malignancies, situations requiring a strong graft-versus-tumor effect, nonmyeloablative stem cell transplantation, and situations requiring a megadose of stem cells. Cytokine-primed peripheral blood stem cells can also be used for adoptive immunotherapy, such as a nonprimed donor lymphocyte infusion.

Abstract
Patients who had suffered chronic GVHD after an allogeneic PBSCT were evaluated using a new chronic GVHD grading system. The study included 36 consecutive adult patients with hematological diseases, who survived at least until day 90 following allogeneic PBSCT and who could be evaluated for chronic GVHD. Extensive skin involvement was observed in five patients, thrombocytopenia in 14, and progressive-type onset in 10, while grade 1 chronic GVHD appeared in 21 patients, grade 2 in 10, and grade 3 in five. There was a significant difference in the probability of relapse between the groups with grade 1 and 2+3 chronic GVHD (55.3 vs 16.4%, P=0.0211). The difference was particularly marked in patients with high-risk hematological malignancies (grade 1 vs grade 2+3, 75 vs 0%, P=0.0115). With a median follow-up of 12 months (range, 4-52 months), 22 (66.1%) patients were still alive. The estimated 2-year survival rate for the whole population was 57.6%, while that for the group with chronic GVHD grade 1 and grade 2+3 was 53.5 and 56.3%, respectively (P=0.4387). Accordingly, there was a significant difference in the probability of relapse between the groups with grade 1 and grade 2+3 chronic GVHD.

Abstract
Although the use of peripheral blood stem cells instead of bone marrow is still a matter of debate in transplantation from HLA-identical sibling donors, allogeneic peripheral blood stem cell transplantation (PBSCT), with a stronger graft-versus-leukemia (GVL) effect, may be preferable as a source of stem cells, especially in the case of advanced hematologic diseases. As such, the current paper reports on the outcomes of 27 consecutive patients with high-risk hematologic diseases treated with allogeneic PBSCT. The median dose of CD34+, CD3+ cells, and MNC infused was 8.18 x 10(6)/kg (range: 2.78-14.93), 1.50 x 10(8)/kg (range: 0.06-4.25), and 7.17 x 10(8)/kg (range: 0.95-15.85), respectively. The median time taken for the ANC and platelets to reach 500 and 20,000 x 10(6)/microL was 15 (range: 9-25) and 16 d (range: 10-56), respectively. Three patients (11.1%) experienced transplant-related mortality within 90 d of transplantation, and 15 (62.5%) of 24 evaluated patients developed chronic graft-versus-host disease (GVHD; six limited, nine extensive). There was a significant difference in overall survival (OS) between the group with chronic GVHD and the group without chronic GVHD (P = 0.0253). The causes of death included relapse (six cases) and non-relapse mortality (infection: four cases, chronic GVHD-related death: three cases). The 4-yr OS rate and disease-free survival rate was 43.3 +/- 10.9% and 35.8 +/- 10.2%, respectively. Accordingly, chronic GVHD was found to have a positive role in patients with high-risk hematologic diseases that received allogeneic PBSCT.

Abstract
Between March 1997 and January 2002, 18 consecutive patients (18-47 years) with hematological malignancies and previous proven invasive fungal infection underwent stem cell transplantation (SCT) (10 matched sibling allograft, 6 autograft, and 2 haploidentical). All patients had full myeloablative conditioning. The fungal pathogens diagnosed were Aspergillus (14), Fusarium (2), Mucor (1), Exserohilum (1), and Candida (1), involving the lungs (15), sinuses (5), and liver (1). All patients were treated pre- and during transplant with systemic antifungal therapy. Eleven out of 18 (61%) patients survived the transplant. Only 1 of 5 patients who transplanted with an active fungal infection accompanied with active leukemia survived the transplant, compared with 10/13 (84%) survivals in patients who had no clinical and radiological signs of infection or active leukemia (P < 0.025). None of the autografted patients has died, compared with 7/12 allografted patients, of whom 5 underwent transplant with active hematological/active fungal disease. In only 3 patients was the cause of death reactivation of previous fungal infection. Both active fungal infection and active leukemia place patients at a very high risk for procedure-related mortality. Pre-transplant therapy of fungal infection, aiming to achieve a clinically undetectable state of infection, followed by an antifungal treatment during transplant may allow the SCT with no fungal reactivation in selected patients.

Abstract
We report on a 9-yr-old boy suffering from primary refractory AML. Remission was not achieved after two courses of induction therapy, leading to prolonged aplasia for more than 3 months and severe infection. Therefore, the boy was treated with a reduced intensity conditioning regimen consisting of fludarabine, cyclophosphamide and OKT3. Megadose transplantation of highly enriched CD34+ peripheral stem cells from his HLA-identical brother, followed on day +11 by a boost of unmanipulated bone marrow, was performed. Regeneration of donor hematopoiesis was rapid and led to resolution of infection. No additional donor lymphocyte infusions were necessary. More than 4 1/2 yr after the transplant the boy remains in complete continuous remission with no evidence for chronic GvHD or other late effects. Therefore, we conclude that reduced intensity conditioning in combination with allogeneic megadose stem cell transplantation and bone marrow boost may have helped to achieve cure from primary refractory AML as well as a good quality of life for this boy.

Abstract
A review of the published literature, supplemented with a recent analysis of Fred Hutchinson data, has been undertaken to investigate the association of infused CD34 cell dose with various clinical outcomes after HLA-identical transplantation. Separate assessments for unrelated vs related donors and the use of bone marrow or mobilized G-PBMC have been incorporated. The three primary findings are: (1) higher CD34 dose results in better neutrophil and platelet recovery in all settings; (2) high CD34 doses (>8 x 10(6)/kg) are associated with the development of more chronic GVHD when using related G-PBMC; (3) higher CD34 dose is correlated with improved survival after bone marrow transplantation, especially with unrelated donors. This is not seen when using G-PBMC. The data suggest that the CD34 content of the graft can have a significant impact on clinical outcome after allogeneic transplantation, but optimal dose is dependent on both donor type and stem cell source.

Abstract
The aim of this study was to evaluate the outcomes for Philadelphia-chromosome-positive acute lymphoblastic leukaemia (Ph+ ALL) patients in remission treated with allogeneic bone marrow transplantation (BMT). Twenty-three adults were entered onto this study. The 2-year probabilities of relapse and disease-free survival (DFS) were 39.4 +/- 11.6% and 43.5 +/- 10.3% respectively. The presence of chronic graft-versus-host disease (GVHD) was found to be an independent predictive factor affecting lower relapse and DFS. To monitor the BCR-ABL transcript, we also analysed 48 bone marrow samples of eight patients using real-time quantitative reverse-transcription polymerase chain reaction (RT-PCR). The kinetics of the BCR-ABL transcript correlated well with the patients' clinical course. In six patients who were in continuous remission after BMT, a rapid decrease in BCR-ABL copy number to the PCR-negative status was observed after the development of chronic GVHD. Meanwhile, routine bone marrow examination of two patients showed PCR positivity with a 3 or 4-log increase of BCR-ABL copy number and subsequent haematological relapse, which occurred 2 and 4 months later respectively. Although our data should be interpreted cautiously, the presence of chronic GVHD may reduce the risk of relapse in Ph+ ALL. Real-time quantitative RT-PCR appears to be a useful test for BCR-ABL transcript monitoring.

Abstract
Between 1982 and 2000, 172 patients with acute myelogenous leukaemia (AML) received haematopoietic stem cell transplants (SCT) from related (n = 132) or unrelated (n = 40) donors at four Austrian transplant centres and their results were reported to the Austrian Stem Cell Transplantation Registry. Conditioning for SCT consisted of cyclophosphamide and total body irradiation in 156 (91%) patients. Graft-versus-host disease (GVHD) prophylaxis was with standard cyclosporine and methotrexate in 95 (55%) patients. Median post-transplant follow-up was 5.6 years (range, 0.2--16.7). Multivariate analysis of transplant-related mortality (TRM) identified four variables associated with a lower risk: disease status of first complete remission (CR) at SCT, patient age of 45 years and younger, transplant performed during or after 1995, and lack of acute GVHD. Variables associated with significantly improved leukaemia-free survival were: bone marrow as the stem cell source, disease status of first CR at SCT, and occurrence of chronic GVHD. In multivariate analysis, transplantation performed during or after 1995, first CR at SCT, occurrence of limited chronic GVHD and lack of acute GVHD grades III to IV were associated with increased overall survival. Based on these analyses, options for the improvement of results obtained with allogeneic SCT in patients with AML could be defined.

Abstract
Between January 1987 and January 1997, 69 eligible patients with acute myeloid leukaemia (AML) in either second (CR2) or third (CR3) complete remission (CR2 = 60, CR3 = 9) underwent 4-hydroperoxycyclophosphamide-purged autologous bone marrow transplantation (BMT) at the Johns Hopkins Oncology Center. The patients' median age was 27 years (range 1-62) and all received busulphan and cyclophosphamide as their preparative regimen. The probability of event-free survival (EFS) at 5 years was 30% [95% Confidence Interval (CI): 19-42%] for CR2 patients and 22% (3-51%) for those in CR3, with a median follow up of 8 years in the surviving group. The median time to an absolute neutrophil count of 0.5 x 109/l was 45 d (range 20-185). Relapse was the major cause of failure with a relapse rate of 55% in CR2 and 44% in CR3, while the non-relapse, transplant-related mortality rate was 15% in CR2 and 33% in CR3. In univariate analysis, patient age, cytogenetics, white blood cell count at presentation, CR1 duration and the sensitivity of clonogeneic leukaemia (CFU-L) in the graft to 4HC were all prognostic for EFS. Using each of these significant variables in multivariate modelling, patient age and sensitivity of CFU-L to 4HC were determined to be predictors of EFS. 4HC-purged autologous BMT produced results similar to allogeneic BMT for AML patients beyond first remission.

Abstract
The prognostic relevance of karyotype has been established in adult acute lymphoblastic leukaemia (ALL) patients treated with chemotherapy but not definitively evaluated in an allogeneic bone marrow transplantation (BMT) setting. To determine the factors affecting the outcome of allogeneic BMT for adults with precursor B-lineage ALL in first or second complete remission (CR), a total of 41 consecutive patients with a successful karyotype were enrolled in this study. There were 21 men and 20 women with a median age of 27 (15-43) years. The distribution of French-American-British (FAB) subtypes was as follows: L1 (n = 26), L2 (n = 15). Unfavourable karyotypes (n = 12) were defined as Ph+ or t(4;11). Disease status at the time of transplant was first CR (n = 35) or second CR (n = 6). With a median follow-up of 36 months, the 3-year probabilities of relapse and disease-free survival (DFS) were 36.3 +/- 8.4% and 57.3 +/- 8.4% respectively. Potential variables predicting worse relapse and DFS were FAB subtype (L2), extramedullary involvement, pre-BMT status (second CR), unfavourable karyotype and type of graft-versus-host disease (GVHD). Further multivariate analysis showed that karyotype and pre-BMT status were independently associated with relapse and DFS. In addition, chronic GVHD was found to be significantly associated with a lower relapse rate.

Abstract
BACKGROUND Standard allogeneic bone marrow transplantation (BMT) offers only a small chance of cure for most adult patients with advanced hematologic malignancies. The authors postulated that allogeneic peripheral blood stem cell transplantation (PBSCT) followed by prophylactic growth factor-primed donor lymphocyte infusion (DLI) with cells reserved at harvest would maximize the graft-versus-tumor effects in patients with hematologic malignancies who had a high risk of recurrence. METHODS Seventeen patients with hematologic malignancies who had a high risk of recurrence were allocated on an intent-to-treat basis to allogeneic PBSCT from human leukocyte antigen-matched sibling donors followed by prophylactic growth factor-primed DLI of cells reserved at harvest for transplantation. RESULTS The median age was 37 years (range, 19-56 years). All donors underwent two or more apheresis procedures. The median numbers of mononuclear cells (MNCs), CD34 positive (CD34+) cells, and CD3+ cells, respectively, that were collected for 17 donors were 9.0 x 10(8) MNCs/kg (range, 4.9-14.4 x 10(8) MNCs/kg), 13.0 x 10(6) CD34+ cells/kg (range, 2.4-75.2 x 10(6) CD34+ cells/kg), and 5.8 x 10(8) CD3+ cells/kg (range, 3.3-9.9 x 10(8) CD3+ cells/kg) for a mean number of 2.35 apheresis procedures (range, 2.0-4.0 procedures). The median numbers of MNCs and CD3+ cells that were cryopreserved were 2.1 x 10(8) MNCs/kg (range, 0.0-4.4 x 10(8) MNCs/kg) and 1.4 x 10(8) CD3+ cells/kg (range, 0.0-3.5 x 10(8) CD3+ cells/kg). Seven of 17 patients received additional PBSCs, with a median of 5.0 x 10(7) CD3+ cells/kg (range, 3.0-9.9 CD3+ cells/kg) between Day 41 and Day 120. The reasons for inability to administer additional PBSCs in 10 patients included early death (n = 4 patients), severe graft-versus-host disease (GVHD) (n = 3 patients), disease recurrence (n = 2 patients), and harvest failure (n = 1 patient). Of seven patients, two patients died of recurrence, and one died of cytomegalovirus pneumonitis. The surviving four patients were free of disease when last assessed (median follow-up, 597 days) but were suffering from chronic GVHD (one patient had limited GVHD, and three patients had extensive GVHD). CONCLUSIONS The authors suggest that allogeneic PBSCT with prophylactic growth factor-primed DLI may be a potentially curative strategy for the treatment of hematologic malignancies in patients with a high risk of recurrence. Their approach may offer the additional advantage of collecting enough cells at harvest for the potential use of DLI, which is easy, convenient for donors, and cost effective.

Abstract
Relapse is the major cause of death after allogeneic bone marrow transplantation (BMT). This study tested the hypothesis that the numbers of donor mononuclear cells, lymphocytes, and CD34(+) cells influence relapse and event-free survival (EFS) after BMT. The study population consisted of 113 consecutive patients with hematologic malignancies who underwent non-T-cell-depleted BMT from HLA-matched siblings. Sixty-four patients had low-risk diagnoses (ALL/AML CR1, MDS RA/RARS, and CML CP1); 49 patients had high-risk diagnoses (all others). CD34(+) cells, T cells, B cells, natural killer cells, monocytes, and a rare population of CD3(-), CD4(bright) cells in the allografts were measured by flow cytometry. The CD3(-), CD4(bright) cells in bone marrow had the same frequency and phenotype as CD123(bright) type 2 dendritic cell (DC) progenitors, and they differentiated into typical DCs after short-term culture. Cox regression analyses evaluated risk strata, age, gender, and the numbers of nucleated cells, CD3(+) T cells, CD34(+) hematopoietic cells, and CD4(bright) cells as covariates for EFS, relapse, and nonrelapse mortality. Recipients of larger numbers of CD4(bright) cells had significantly lower EFS, a lower incidence of chronic graft-versus-host disease (cGVHD), and an increased incidence of relapse. Recipients of larger numbers of CD34(+) cells had improved EFS; recipients of fewer CD34(+) cells had delayed hematopoietic engraftment and increased death from infections. In conclusion, the content of donor CD4(bright) cells was associated with decreased cGVHD and graft-versus-leukemia effects in recipients of allogeneic bone marrow transplantation, consistent with a role for donor DCs in determining immune responses after allogeneic BMT.

Abstract
Two patients with high-risk acute myeloid leukemia (AML) whose bone marrow aspirates showed more than 25% blasts between 2 and 4 weeks after the first induction chemotherapy immediately received modified conditioning therapy with intravenous busulfan at 50% of the usual dose and fludarabine, before hematologic recovery occurred. Unmanipulated G-CSF mobilized peripheral blood stem cells from an HLA-identical sibling donor were transfused and haematopoietic recovery was achieved in both recipients. Both of them are in continuing hematological remission with full donor chimerism 12 and 22 months after transplantation. Early treatment intensification with allogeneic cell therapy during marrow aplasia might cure high-risk AML patients who are unlikely to achieve remission with conventional chemotherapy protocols.

Abstract
The overall prognosis for patients with relapsed or refractory adult ALL remains poor. Further insight into the biology of ALL is required, and novel therapeutic agents are needed to counter mechanisms of resistance. A palliative approach to the management of multiply relapsed or refractory ALL should be supplanted by enrollment into clinic trials to promote drug discovery. Monitoring of minimal residual disease may allow an earlier intervention before overt clinical relapse and improve outcome; prospective studies are needed. Attainment of a second or later CR should be followed by allogeneic BMT when feasible owing to the paucity of long-term survivors with salvage chemotherapy alone.

Abstract
Acute lymphocytic leukemia remains a difficult disease to treat in adults. Allogeneic bone marrow transplantation can cure some patients with ALL, but GVHD transplant-related mortality and disease relapse remain problematic. Immunotherapeutic approaches aimed at eliminating minimal residual disease and enhancing the GVL effect may decrease relapse rates and improve overall survival. Because of the rarity of this disease in adults, every new patient should be entered in well-designed, peer-reviewed, investigational trial.

Abstract
Twenty-nine consecutive patients with high-risk hematological malignancy aged from 3 to 58 years underwent an unmanipulated graft from an HLA-identical sibling after an irradiation-free preparative regimen consisting of idarubicin (IDA), 21 mg/m2/day administered by continuous infusion on days -12 and -11, followed by busulphan (BU), 4 mg/kg/day orally from day -7 to -4, and cyclophosphamide (CY), 60 mg/kg/day intravenously on days -3 and -2 (IDA-BUCY2). Most clinically relevant extra-hematological regimen-related toxicities consisted of stomatitis observed in all subjects and hemorrhagic cystitis occurred in five cases (17%) within 100 days after transplant. Six patients (21%) developed a grade 2 acute graft-versus-host disease (GVHD) and three (10%) a grade 3 or 4; extensive chronic GVHD was assessed in nine of 22 (41%) evaluable patients. So far, 12 patients have died and 17 are alive, 16 of whom disease-free, 5-41 months after transplant (median, 15 months). The causes of death were related to GVHD in three patients, to sepsis in one and to disease recurrence in the remaining eight. At present, only one of nine relapsed patients is alive. For all patients the actuarial probability of survival (OS) at 1 and 2 years +/- standard error (s.e.) was 63 +/- 9% and 52 +/- 10%, respectively. The actuarial probabilities of disease-free survival (DFS), relapse and transplant-related mortality (TRM) at both 1 and 2 years +/- s.e. were 53 +/- 9%, 35 +/- 9% and 16 +/- 7%, respectively. These results are encouraging but not substantially different from those obtained in 28 patients with malignancy in advanced phase transplanted after the standard BUCY2 regimen, who had an actuarial probability of OS, DFS, relapse and TRM projected at 10 years +/- s.e. of 54 +/- 10%, 57 +/- 9%, 36 +/- 9% and 11 +/- 6%, respectively. Although the retrospective comparison between the two groups does not seem to show any advantage in the use of the IDA intensified regimen, only a prospective randomized trial could answer this question.
