Abstract
Forkhead box O1 (FOXO1) is a key regulator of osteogenesis. The aim of this study was to identify the mechanisms of microRNAs (miRNAs) targeting FOXO1 in osteogenic differentiation of human bone marrow mesenchymal stem cells (hMSCs). Three miRNA target prediction programs were used to search for potential miRNAs that target FOXO1. Quantitative real-time polymerase chain reaction was conducted to detect the expression of miR-1271-5p and FOXO1 during osteogenic differentiation. Target gene prediction and screening, luciferase reporter assay was used to verify the downstream target gene of miR-1271-5p. The expression levels of FOXO1 and Runx2 were detected by RT-qPCR and Western blot analysis. Alkaline phosphatase (ALP) activity and matrix mineralization were detected by biochemical methods. The expression levels of Runx2, ALP, and osteocalcin were detected by RT-qPCR. Our results showed that miR-1271-5p was downregulated during osteogenic induction. And the expression levels of miR-1271-5p were higher in osteoporotic tissues than that in adjacent nonosteoporotic tissues. The expression levels of FOXO1 were lower in osteoporotic tissues than that in adjacent nonosteoporotic tissues. And a negative correlation was found between miR-1271-5p and FOXO1 in osteoporotic tissues. Overexpression of miR-1271-5p downregulated FOXO1 and inhibited osteogenic differentiation in hMSCs. Overexpression of miR-1271-5p downregulated the expression of osteogenic markers and reduced ALP activity. In addition, ectopic expression of FOXO1 reversed the effect of miR-1271-5p on osteogenic differentiation. In conclusion, miR-1271-5p functioned as a therapeutic target of osteogenic differentiation in hMSCs by inhibiting FOXO1, which provides valuable insights into the use of miR-1271-5p as a target in the treatment of osteoporosis and other bone metabolic diseases.

Abstract
The indications for bone marrow transplantation (BMT) continue to expand as supportive care improves and alternative stem cell sources have been exploited. The application of allogeneic BMT has expanded to include unrelated histocompatibility antigen-matched donors and partially matched family donors. While the results of these transplants are not as good as those with sibling donors, these alternative donors allow curative therapy to be delivered to patients with leukemia, aplastic anemia, and immunodeficiency diseases who otherwise would not be eligible for curative therapy. Autologous BMT has emerged as a curative therapy for patients with non-Hodgkin's lymphoma, Hodgkin's disease, acute myeloid leukemia, and acute lymphoblastic leukemia. In addition, dose-intensive therapy with marrow or peripheral blood stem cell support to patients with Stage II, III, and IV breast carcinoma is under intense study in single and multiple-institution studies. Important issues under active study are prophylaxis for graft-versus-host-disease, the role of marrow purging in autologous BMT, the use of cytokine and chemotherapy-mobilized peripheral blood stem cells, and control of infectious diseases. This review summarizes current results in both allogeneic and autologous bone marrow transplantation, issues in marrow graft manipulations, issues in infectious disease control, the application of gene therapy to correct genetic disease through bone marrow or peripheral blood infusion, and current concepts in post-BMT immunization.

Abstract
Hematopoietic stem cell transplantation (HSCT) and consolidation chemotherapy have been used to treat intermediate-risk acute myeloid leukemia (AML) patients in first complete remission (CR1). However, it is still unclear which treatments are most effective for these patients. The aim of our study was to analyze the relapse-free survival (RFS) and overall survival (OS) benefit of allogeneic HSCT (alloHSCT) for intermediate-risk AML patients in CR1. A meta-analysis of prospective trials comparing alloHSCT to non-alloHSCT (autologous HSCT [autoHSCT] and/or chemotherapy) was undertaken. We systematically searched PubMed, Embase, and the Cochrane Library though October 2014, using keywords and relative MeSH or Emtree terms, 'allogeneic'; 'acut*' and 'leukem*/aml/leukaem*/leucem*/leucaem*'; and 'nonlympho*' or 'myelo*'. A total of 7053 articles were accessed. The primary outcomes were RFS and OS, while the secondary outcomes were treatment-related mortality (TRM) and relapse rate (RR). Hazard ratios (HR) and 95% confidence intervals (CI) were calculated for each outcome. The primary outcomes were RFS and OS, while the secondary outcomes were TRM and RR. We included 9 prospective controlled studies including 1950 adult patients. Patients with intermediate-risk AML in CR1 who received either alloHSCT or non-alloHSCT were considered eligible. AlloHSCT was found to be associated with significantly better RFS, OS, and RR than non-alloHSCT (HR, 0.684 [95% CI: 0.48, 0.95]; HR, 0.76 [95% CI: 0.61, 0.95]; and HR, 0.58 [95% CI: 0.45, 0.75], respectively). TRM was significantly higher following alloHSCT than non-alloHSCT (HR, 3.09 [95% CI: 1.38, 6.92]). However, subgroup analysis showed no OS benefit for alloHSCT over autoHSCT (HR, 0.99 [95% CI: 0.70, 1.39]). In conclusion, alloHSCT is associated with more favorable RFS, OS, and RR benefits (but not TRM outcomes) than non-alloHSCT generally, but does not have an OS advantage over autoHSCT specifically, in patients with intermediate-risk AML in CR1.

Autologous Stem Cell Transplantation in elderly Acute Myeloid Leukemia. Mediterr J Hematol Infect Dis 2013; 5:e2013018.

Abstract
Treatment outcome in elderly Acute Myeloid Leukemia (AML) is still very disappointing. Although complete remission rate is around 50–60% the 2 years survival is only in the magnitude of 10–20%. This is mainly due to an overrepresentation of adverse prognostic factors present in elderly AML. As relapses emerge from residual disease present after chemotherapy, intensification of treatment could emerge as a rational strategy. Intensification of chemotherapy by increasing the dose of anthracyclines or addition of gemtuzumab ozogamycin (Mylotarg) to standard chemotherapy indeed has proved to be of advantage in elderly AML. In younger AML autologous peripheral blood stem cell transplantation (AuPBSCT) as post remission treatment in comparison to intensive consolidation chemotherapy has been investigated in a few randomized studies. AuPBSCT showed reduced relapse rates with low non-relapse mortality rates. In elderly AML intensification by AuPBSCT also have been performed although randomized studies are lacking. Nevertheless, in the previous years various reports have suggested the potential utility of AuHSCT in AML of the elderly with encouraging results, albeit mostly in highly selected patients. Acceptable toxicity and a relatively low rate of transplant-related mortality has been notified. However relapses occurred which, irrespective of age, still remains the major cause of treatment failure of AuHSCT in AML. In this review we summarize the experience of AuPBSCT in elderly AML.

Abstract
The medical records of 99 patients with acute myeloid leukemia (AML; except AML, M3) in the first remission from 1995 to 2004 were retrospectively reviewed. When they achieved complete remission, at first complete remission (CR1), patients received allogeneic (n = 23), autologous hematopoietic stem cell transplantation (HSCT) (n = 35), or intensive chemotherapy (n = 41) according to prognostic factors and donor availability. There was an advantage in terms of event-free survival (EFS, p = 0.0001) and overall survival (OS, p = 0.0002) with HSCT as compared to those of intensive chemotherapy. However, the EFS and OS were not different between allogeneic HSCT and autologous HSCT. In high-risk patients, the EFS and OS of allogenic or autologous HSCT group were higher compared with those in the intensive chemotherapy group (p < 0.01). However, there was no difference between allogeneic HSCT and autologous HSCT in terms of EFS and OS. In the intermediate- or low-risk group, there was no significant difference in the outcome according to the postremission modalities.

Abstract
Post-remission therapy in acute myeloid leukemia (AML) remains problematic. It has been demonstrated that younger patients can maintain longer complete remissions (CR) with aggressive post-remission therapies after induction treatment: allogeneic (allo), autologous (auto) stem cell transplantation (SCT), or intensive chemotherapy (ICC). The purpose of our study was to identify the most important randomized and controlled studies comparing these three therapeutic options, in order to draw conclusions and possible suggestions for post-remission therapy of AML, according to the evidence based medicine (EBM) rules. We performed an exhaustive analysis of the literature, searching either in electronic databases or among the references of the identified articles (hand searching). We searched the MEDLINE computer database for reports from 1985 through January 2005 and selected for analysis the clinical trials conducted over adults affected by newly diagnosed AML aged less than 65 years. The study design had to satisfy strict methodological criteria and must consider global mortality and/or disease free survival as primary outcomes. Overall we found 7750 papers; by using the limits "clinical trial" as publication type, "all adults 19+ years", we were able to select 344 papers. Among these, a further selection was made, based on two main clinical queries: 1) is auto-SCT superior to ICC/no other therapy in improving DFS and/or OS in adult AML patients in first CR? 2) is allo-SCT superior to auto-SCT/other therapeutic options in improving DFS and/or OS in adult AML patients in first CR? Concerning the first query, a possible advantage of auto-SCT over ICC was not clearly supported by data from clinical trials; there is no evidence that auto-SCT is superior in terms of OS to chemotherapy. Nevertheless, the reported TRM has been significantly reduced within the past years. Thus, the percentage of patients suitable for auto-SCT in CR has increased. Moreover, the scarce data concerning the comparison between auto-SCT and chemotherapy in different subsets of patients are unable to suggest a differentiated approach in patients with high-risk, standard-risk or low-risk AML. Data from the literature show that patients with unfavorable risk disease are more often addressed to allo-SCT and patients with low-risk disease receive more often intensive consolidation chemotherapy. Concerning the second query, interpretation of data from the main prospective studies about the role of allo-SCT in previously untreated AML is not easy. The first problem is the lack of real randomized clinical trials; in fact, according to the reported studies, AML patients generally receive allo-SCT on the basis of donor availability (the so called "genetic randomization"). The second problem is the frequent absence of intention to treat analysis. Despite methodological limitations, it was possible to compare allo-SCT with auto-SCT on a donor versus no-donor analysis and within risk groups. No overall benefit of allo-grafting on survival was demonstrated by any trial. In conclusion, the EBM approach highlighted the limitations observed in the published studies concerning consolidation therapy in AML; some suggestions, emerging from non-randomized, as well as randomized studies, are adequate, but not conclusive. This point, coupled with the intrinsic complexity to study AML biological heterogeneity, is probably a major obstacle to draw conclusive evidences for consolidation therapy in AML. These observations should plan to address new randomized studies on AML therapy; however, due to the emergence of genetic subgroups and new drugs targeting specific abnormalities, these trials should probably be designed directly focusing on the single entities. In this way, the cure of AML could eventually become the cure of each specific AML subset with its peculiar biological, molecular and prognostic features.

Abstract
Most adult patients under 60 years with acute myeloid leukaemia (AML) who achieve a complete remission after induction chemotherapy will relapse if they do not receive further therapy. Consolidation treatment with autologous stem cell transplantation (SCT) is one option that has been studied extensively. High-dose cytotoxic therapy followed by autologous SCT or intensive cycles of chemotherapy furnish overall approximately similar probabilities of survival when applied in first remission. Here, we present a concise update regarding the place of autologous SCT in the treatment of AML. Particular issues discussed are the value of autologous SCT in different prognostic subsets of AML and the value of autologous mobilised peripheral blood stem cell transplants, which offer a much faster haematopoietic recovery.

Abstract
Purpose We analyzed the impact of allogeneic stem-cell transplantation (alloSCT) as an early consolidation for young patients with acute myeloblastic leukemia in first complete remission (CR1) through four successive protocols. Patients and Methods Of the 472 patients who achieved CR1, 182 (38%) had an HLA-identical sibling (donor group), and alloSCT was performed in 171 patients (94%). Of the 290 patients without donor (no-donor group), 62% received an autologous SCT. Results In an intent-to-treat analysis based on donor availability, the overall 10-year survival probability was 51% v 43% (P = .11) for the donor and no-donor groups, respectively. A Cox analysis determined that four factors had independent prognostic significance for survival (initial WBC count, French-American-British subtypes, cytogenetic risk, and number of induction courses). This permitted constitution of a simple index that reclassified 21% of the patients compared with usual cytogenetic classification and identified three subpopulations with different outcome and different impact of alloSCT. Conclusion AlloSCT was associated with a survival advantage for an intermediate-risk group. In other groups, numbers are limited for definitive conclusion. However, early performed alloSCT does not seem to be the optimal treatment of high-risk patients or offer any advantage over intensive chemotherapy in low-risk patients.

Abstract
We report on a randomized trial aimed to determine the impact of a second consolidative high-dose cytarabine-based chemotherapy (HiDAC) in patients with acute myeloid leukaemia prior to an autologous stem cell transplantation (ASCT). Patients aged 18-60 years, in complete remission (CR) received a first consolidation with daunorubicin and cytarabine at reduced dose. Patients not allocated to allogeneic transplantation received one course of HiDAC and then were randomized to receive an ASCT immediately (HiDAC 1 group) or after one more course of HiDAC (HiDAC 2 group). Out of the 437 initial patients, 351 achieved CR (80%), of those 277 (79%) were eligible for first HiDAC, and 128 (36%) were randomized (HiDAC 1:65, HiDAC 2:63). Overall survival, leukaemia-free survival and cumulative incidence of relapse and non-relapse deaths were 41% and 53% (P = 0.14), 39% and 48% (P = 0.12), 57% and 47% (P = 0.11), 8% and 8% (P = 0.95) for HiDAC 1 and HiDAC 2 groups, respectively. Further studies are warranted with a larger number of patients to test the place of a second course of HiDAC in this setting.

Abstract
The question as to whether autologous stem cell transplantation (SCT) after consolidation chemotherapy improves the probability of survival of patients with acute myeloid leukaemia (AML) in first remission has not been settled. Here, we present the results of a phase III study conducted in newly diagnosed adult AML patients aged <60 years. Patients who had reached a complete remission (CR) after two courses of induction chemotherapy and who were not eligible for a human leucocyte antigen-matched sibling SCT (n = 130), were randomized after a third consolidation cycle of chemotherapy between high-dose cytotoxic treatment and autologous bone marrow transplantation or no further treatment. No significant differences in disease-free survival and overall survival were observed between the two treatment arms. A slightly better overall survival in the no further treatment arm was because of fewer deaths in the first CR and a significantly better overall survival after the first relapse. The results are discussed in relation to the generic problems of applying autologous transplantation and in the perspective of the limited statistical power of this and other previously published studies.

Abstract
Interleukin-15 (IL-15) is a pleiotropic proinflammatory cytokine with inefficient posttranscriptional processing. We hypothesized that endogenous IL-15 could affect disease progression in the well-described C57Bl/6 (B6)-->(C57Bl/6 x DBA/2) F1 hybrid (B6D2F1) murine model of acute allogeneic graft-versus-host disease (GVHD). B6D2F1 allogeneic recipients received transplants of IL-15(-/-) B6 bone marrow cells or B6 bone marrow cells expressing a murine IL-15 transgene (IL-15 tg) modified for efficient translation and secretion. Mice that received transplants of IL-15(-/-) B6 bone marrow cells displayed a significantly longer median survival time (MST) compared with mice that received transplants of wild-type (wt) B6 bone marrow; in contrast, mice that received transplants of IL-15 tg B6 bone marrow cells had a dramatically decreased MST. This decrease in survival was associated with a substantial activation and expansion of effector-memory (CD44highCD62Llow) CD8+ T lymphocytes. Finally, in vivo depletion of either CD4+ or CD8+ T lymphocyte subsets significantly prolonged survival in mice receiving IL-15 tg B6 marrow, while depletion of both CD4+ and CD8+ T cells provided complete protection from acute GVHD. We thus show that acute GVHD is attenuated in the absence of donor bone marrow-derived IL-15 and conclude that donor-derived IL-15 is a critical mediator of T-cell function in acute GVHD.

Abstract
In the present study, we have conducted a meta-analysis comparing autologous bone marrow transplantation (ABMT) and intensive chemotherapy in adult acute myeloid leukemia (AML) patients in first remission. Combined results of the six appropriate randomised controlled studies indicate that ABMT had no advantage over chemotherapy or no further treatment concerning death rate (overall rate ratio (RR)-0.95, 95% CI, 0.81-1.11), while was superior to chemotherapy concerning event rate (overall RR--0.82, 95% CI, 0.71-0.94). In conclusion, ABMT did not improve survival but it improved event-free survival (EFS) when compared with chemotherapy or no further treatment in patients with AML in first complete remission.

Abstract
Haematopoietic stem cell transplantation (HSCT) is an established curative treatment for many malignant and non-malignant diseases. Over the last two decades, novel approaches have resulted in significant reductions in the morbidity and mortality associated with HSCT. These include the utilisation of reduced intensity regimens, more effective graft versus host disease prophylaxis, exploration of new sources of progenitor haematopoietic stem cells and better prophylaxis and treatment of infections. Despite current advances, new strategies are needed to further reduce the complications associated with HSCT. This article reviews the current indications for HSCT and the recent progress in the field of both allogeneic- and autologous HSCT.

Abstract
BACKGROUND The optimal consolidation therapy for adults who are in first remission of acute myeloid leukemia after induction chemotherapy and who do not have a histocompatible donor is poorly established. We conducted a meta-analysis to compare the efficacy of autologous bone marrow transplantation with that of non-myeloablative chemotherapy alone (or no further treatment). METHODS Eligible studies were identified by searching electronic databases and by examining the reference lists of relevant studies and review articles. Eligible studies were those that prospectively enrolled adults with acute myeloid leukemia and randomly assigned patients who were in first remission and who did not have a matched sibling donor to one of the two consolidation therapies. Two reviewers independently assessed all studies for relevance and validity. We used a fixed-effects model to calculate the ratio of probabilities for disease-free and overall survival at 48 months or at the nearest recorded assessment point for each study and for all studies combined. All statistical tests were two-sided. RESULTS We identified 587 potentially relevant studies, 36 of which were retrieved for detailed evaluation. In the six studies eligible for this meta-analysis, a total of 1044 patients were randomly assigned to receive autologous bone marrow transplantation or non-myeloablative chemotherapy (five studies) or autologous bone marrow transplantation or no further treatment (one study). Compared with patients who received chemotherapy or no further treatment, patients who received autologous bone marrow transplantation had a better disease-free survival (ratio of disease-free survival probabilities = 1.24, 95% confidence interval [CI] = 1.06 to 1.44; P =.006) but a similar overall survival (ratio of overall survival probabilities = 1.01, 95% CI = 0.89 to 1.15; P =.86). CONCLUSION Our results do not support the routine use of autologous bone marrow transplantation in adult acute myeloid leukemia patients in first remission.

Abstract
The objective of the study was to assess the long-term outcome and impact of stem cell source in patients with acute myelogenous leukemia (AML) who received ASCT in first complete remission (CR). A total of 101 patients (median age 46 years) were included in the study. Cytogenetic categories distribution was: favorable: 18%, intermediate: 42%, and unfavorable: 7%. More than one induction course was needed for CR in 21% of patients. In all, 78% of patients had received at least one course of high-dose ara-C before autologous stem cell transplantation (ASCT). Bone marrow (n=58) or peripheral blood stem cells (PBSC) (n=43) transplantation was performed at a median of 3.5 months from CR. Hematologic recovery and hospitalization duration were significantly reduced in the PBSC group. No toxic death was recorded in this group. The median follow-up of survivors is 67 months (range: 15-183). The 6-year survival, disease-free survival (DFS), and relapse probabilities are 44%, 38%, and 54%, respectively. The presence of a favorable karyotype and the use of PBSC are independently associated to better survival, and DFS by multivariate analysis. Our results confirm that long-term DFS can be achieved with high-dose chemotherapy and ASCT in patients with AML. They show that use of PBSC is associated to very low mortality rate and acceptable morbidity and contributes to an improvement of autotransplant results.

Abstract
Based on our previous demonstration that quinine could be used clinically to reverse P-glycoprotein-mediated resistance, we designed a multicenter, randomized trial aiming to determine whether quinine would improve the survival of adult patients (15-60 years old) with de novo acute myelogenous leukemia (AML). These patients randomly received (n = 213) or did not receive (n = 212) a 30 mg/kg/day continuous intravenous infusion of quinine in combination with induction chemotherapy combining idarubicine and cytarabine and, depending on bone marrow examination at day 20, an additional course of cytarabine and mitoxantrone. The mean steady-state quinine concentration was 7.8 mg/L and the mean multidrug resistance reversing activity of serum was 1.96. Complete remission (CR) was obtained in 344 patients (80.9%) without significant influence of quinine. Of the patients in complete remission, 82 were assigned to receive HLA-matched bone marrow transplants, whereas 262 were assigned to 2 courses of intensive consolidation chemotherapy, with or without quinine, depending on initial randomization. The 4-year actuarial overall survival (OS) of the 425 eligible patients was 42.0% +/- 2.5%, without significant influence of quinine. Of 160 patients who could be studied, 54 demonstrated rhodamine 123 efflux. In these patients, quinine significantly improved the CR rate from 12 of 25 (48.0%) to 24 of 29 (82.8%) (P =.01). However, there was no significant difference in OS. Neither mdr1 gene nor P-glycoprotein expression influenced the outcome. We conclude that quinine does not improve the survival of adult patients with de novo AML, even though it improves CR rate in a small subgroup of patients defined by rhodamine 123 efflux.

Abstract
The objective of this study was to use survival-weighted psychometric scores (SWPS) to construct a 'health profile' for long-term survivors of acute myelogenous leukemia (AML). The study cohort included all patients who had been diagnosed and treated in our institution from 1985 to 1999 and achieved complete remission after standard chemotherapy (n = 259). One hundred and four patients were interviewed by the European Organization for the Research and Treatment of Cancer (EORTC)-QLQ-C30 questionnaire and the brief form of World Health Organization quality of life questionnaire (WHOQOL-BREF) to estimate the quality of life (QOL) function of the cohort. Forty-one patients underwent bone marrow transplantation (BMT) as consolidation or salvage therapy; 63 received chemotherapy alone. SWPS for every functioning domain and symptom item was obtained by direct integration of the mean QOL function with the survival function of the cohort. A Monte Carlo method was used to extrapolate the life-long SWPS beyond the follow-up limit. The mean scores of EORTC-QLQ-C30 and WHOQOL-BREF did not differ significantly between patients who received BMT or those who received chemotherapy only (p > 0.01). In mean SWPS, patients who received BMT had significantly (p < 0.01) better SWPS in all of the functioning domains and symptom items of EORTC-QLQ-C30 and all four domains of WHOQOL-BREF. However, when the life-long extrapolation of SWPS was made, these differences diminished in global health and several symptom items of EORTC-QLQ-C30 as well as in the social and environmental domains of WHOQOL-BREF. Patients' perspective on QOL may be domain-specific and may evolve over time. SWPS may be useful to evaluate the efficacy of different treatment strategies for AML. Confirmation of the relative merit of BMT vs. chemotherapy alone from prospective studies is needed.

Abstract
Introduction of the HSV-Tk suicide gene into allogeneic T cells offers the possibility to control developing host-reactive cells within the context of allogeneic bone marrow transplantation (BMT). Sensitive quantitative detection methods are a prerequisite to monitor genetically modified T cells in peripheral blood and tissues to study their involvement in graft-versus-host disease (GVHD)-induced lesions as well as their disappearance or persistence after ganciclovir (GCV)-induced suicide. We monitored the alloreactivity of HSV-Tk-transduced T cells after BMT by studying their in vivo distribution and quantity in peripheral blood and in tissues in a WAG/Rij into Brown Norway fully mismatched rat allogeneic BMT model. Genetically modified T cells were quantified in blood and tissues by fluorescence-activated cell sorting, immunohistochemical analysis, and real-time quantitative polymerase chain reaction (PCR) analysis. A significant increase in the number of allogeneic HSV-Tk(+) T cells was found in particular in spleen and lymph nodes and large numbers were found in tongue, skin, and intestines. In blood, an increase in HSV-Tk(+) T cells closely preceded clinical symptoms of GVHD. Real-time quantitative PCR proved to be a fast and accurate tool by which to quantify transduced T cells both in blood and tissues. This enables the study of the in vivo alloreactivity of retrovirus-transduced cells and the response of HSV-Tk-expressing T cells to GCV-induced suicide therapy. Furthermore, we showed the potential use to study specific cause-effect relationships in a broad range of animal and clinical studies involving genetically engineered cells.

Abstract
BACKGROUND The role of allogeneic bone marrow transplantation (BMT) in the consolidation of young adults with acute myeloid leukemia (AML) with matched sibling donors (MSD) is controversial. Although BMT is associated with increased event free survival compared with intensive chemotherapy (CT) consolidation, BMT also is associated with increased treatment-related mortality and likely decreased quality of life and life expectancy in patients who do not develop recurrent disease. METHODS The authors used decision analysis to compare three strategies for maximizing quality-adjusted life years (QALYs) in patients with AML in first remission with an MSD: BMT All, BMT None (consolidation CT only), or BMT in high-risk patients, as defined by baseline cytogenetic testing (Test strategy). A second decision-analysis tree was then constructed that compared BMT with CT specifically for patients with intermediate cytogenetics. RESULTS Using expected QALYs as the outcome measure, the Test, BMT All, and BMT None strategies were associated with 20.10 QALYs, 19.63 QALYs, and 18.38 QALYs, respectively. Thus, the Test strategy, with CT for low-risk patients and BMT for intermediate risk and high-risk patients, was expected to be the optimal strategy. In the intermediate cytogenetic decision analysis, although the expected QALY for BMT recipients was higher compared with CT recipients (19.78 QALYs vs. 18.75 QALYs), because of uncertainty in variable estimates, the optimal choice was less clear. CONCLUSIONS CT consolidation is a reasonable option for patients with AML who have favorable cytogenetics, even if an MSD is available. This model provides a framework from which patients with AML and their physicians can make decisions about consolidation therapy.

Abstract
Variable numbers of CD34+ cells can be harvested from the blood of AML patients in CR after G-CSF supported mobilization following consolidation chemotherapy. We hypothesized that a decreased ability to mobilize stem cells reflects a chemotherapy-induced reduction in the number of normal and leukemic stem cells. We therefore analyzed whether the mobilizing capacity of these patients was of prognostic significance. 342 AML-patients in first CR received daily G-CSF from day 20 of the consolidation course and underwent 1-6 aphereses to obtain a minimum dose of 2 x 10(6) CD34+ cells/kg. Afterwards they were randomized for autologous bone marrow (BM) or blood SCT. As a surrogate marker for the mobilizing capacity, the highest yield of CD34+ cells of a single apheresis was adopted. Patients could be categorized into four groups: no harvest (n = 76), low yield (<1 x 10(6) CD34+/kg; n = 50), intermediate yield (1-6.9 x 10(6) CD34+ cells/kg; n = 128) and high yield (> or = 7 x 10(6) CD34+ cells/kg; n = 88). The median follow-up was 3.4 years; 163 relapses and 16 deaths in CR were reported. Autologous blood or BM SCT was performed in 36%, 64%, 81% and 88%, respectively, of the patients assigned to the no harvest, low, intermediate and high CD34+ yield group. The 3-year disease-free survival rate was 46.7%, 65.0%, 50.4% and 26.9% (P = 0.0002) and the relapse incidence was 47.5%, 30.1%, 43.1% and 71.9% (P < 0.0001). Multivariate Cox's proportional hazards model showed that the CD34+ yield was the most important independent prognostic variable (P = 0.005) after cytogenetics. Patients with the highest mobilizing capacity have a poor prognosis due to an increased relapse incidence.

Abstract
Acute myelogenous leukemia (AML) describes a group of related hematologic malignancies that are being approached therapeutically from several perspectives. Conventional chemotherapeutic agents, such as anthracyclines and cytosine arabinoside (Ara-C), are useful in treating AML but now appear to have reached their maximum potential. Newer therapeutic approaches to AML have recently focused on immune-based therapy through monoclonal antibodies that target and destroy malignant cells via specific cell receptors. One such agent is gemtuzumab (CMA-676), an agent that targets the CD33 antigen on malignant myeloid cells. Initial studies have shown significant anticancer activity. We will discuss traditional and newer therapeutic approaches to AML and review the role of monoclonal antibody based therapies for patients with AML. A case of a 30-year-old man with refractory AML who was treated with gemtuzumab will be mentioned, highlighting potential applications and possible limitations to this novel therapy. Despite the effective reduction in the number of malignant cells in bone marrow, gemtuzumab ineffectively treated extramedullary leukemic gingival infiltrate. Regardless of limitations, monoclonal-based therapy offers an exciting and potentially safer adjunctive therapy for patients with AML.

Between August 1993 and January 1999, 17 patients, median age 26 (4-44) years, underwent T cell depleted bone marrow transplant from partially mismatched related donors (PMRD), as a salvage for AML relapsing after an autograft. The median time from auto-transplant to relapse was 7 months (1.5-24) and the interval between transplants was 10 months (3-30). All patients had active leukemia at time of transplant. Donors were siblings (n = 8), parents (n = 2), daughters (n = 4) and others (n = 3), and 82% were > or = 2 major HLA antigen mismatched with the recipient. The conditioning therapy included total body irradiation in 14 patients and was busulfan-based in three. Graft-versus-host disease (GVHD) prophylaxis consisted of partial T cell depletion along with post-transplant immunosuppression. Median day to engraftment was 16 days (12-20). Acute GVHD was seen in six patients, and chronic GVHD in four of 13 surviving beyond 100 days. Ten patients died of non-relapse causes, at 1-588 (median 77) days. Two patients relapsed at 3 and 4 months. Five patients (29%) are surviving leukemia-free 42-84 months post transplant (median 68 months). A short interval between transplants was predictive of early relapse but not mortality. Age <18 and <2 organ toxicities were marginally predictive of better survival. We conclude that BMT from PMRD is a reasonable option for patients with refractory AML post autograft.

Abstract
Conventional chemotherapy of acute myelogenous leukemia (AML) results in an overall long-term disease-free survival of less than 50%, but for selected subsets of younger patients the prognosis can be improved by allogeneic stem cell transplantation. The use of autologous stem cell transplantation is now investigated as an alternative to allotransplantation due to its lower risk of serious complications. However, autotransplantation is associated with a relatively high risk of post-transplant AML relapse that can be derived from contaminating leukemia cells in the autograft. Peripheral blood mobilized stem cell (PBSC) grafts usually contain a higher number of platelets. The degree of platelet contamination is determined by the peripheral blood platelet count at the time of harvesting, and the platelets become activated and release soluble mediators during the ex vivo handling of PBSC grafts. Many of these platelet-derived mediators can bind to specific receptors expressed by AML blasts, and the platelet contamination may then alter AML blast survival and thereby influence the risk of post-transplant leukemia relapse. Therefore, we conclude that the platelet contamination of autologous stem cell grafts is possibly of clinical importance, but the effect of this nonstandardized parameter is difficult to predict in individual patients because the number of graft-contaminating platelets, the degree of platelet activation, and the effects of platelet-derived mediators on AML blasts differ between patients.

Abstract
Roquinimex, Linomide, a quinoline derivative with pleiotropic immunomodulatory activity, has previously been shown to enhance natural killer (NK) cell number and activity after ABMT in patients with AML. In this study 278 AML patients in remission were randomized to receive Roquinimex 0.2 mg/kg body weight or placebo twice weekly for 2 years following ABMT. Out of 139 patients in each group, 109 Roquinimex patients and 108 placebo patients were in their first CR. Median age at inclusion was 41 years for Roquinimex patients and 39 years for placebo patients. Twelve patients in each group had their marrow purged prior to reinfusion. Relapse and death were study endpoints. Surviving patients were followed for 2.6 to 6. 9 years. The total number of relapses was 60 in the Roquinimex group and 63 in the placebo group (not significant). Leukemia-free and overall survivals were similar in the two groups. Recovery of platelet counts was significantly delayed in the Roquinimex group as compared to placebo. No other significant differences regarding toxicity parameters were recorded. In conclusion, previous findings on NK cells could not be confirmed and the study showed no benefit for Roquinimex over placebo regarding relapse or survival following ABMT for AML in remission.

Abstract
PURPOSE To describe quality-of-life considerations in post-remission therapies for children with acute myelogenous leukemia. PATIENTS AND METHODS A quality-adjusted survival analysis, using the quality-adjusted time without symptoms or toxicity (Q-TWiST) method, was applied to Pediatric Oncology Group Trial 8821, which compared randomized assignment with intensive consolidation chemotherapy (CC) or autologous bone marrow transplantation (ABMT). Nonrandomized assignment to allogeneic bone marrow transplantation (allo BMT) on the basis of availability of a matched related donor was also evaluated. A 25-patient cohort provided data for modeling chronic graft-versus-host disease. The Q-TWiST analysis was performed based on the intent-to-treat principle. RESULTS As previously reported, the 3-year event-free survival was not significantly different between the randomized arms (CC v ABMT). At a median follow-up of 5 years (of the censoring distribution), the CC group had less time in toxicity (TOX) and more time without symptoms or toxicity (TWiST), relapse-free time, and alive time than patients assigned to ABMT (none of these were statistically significant). Compared with the CC group, allo BMT patients spent more time in TOX (P <.001), more time in TWiST (P =.06), and had more relapse-free time (P =.03) and time alive (P =.07). Allo BMT was superior to ABMT with greater time in TWiST (P =.02), relapse-free time (P =.01), and time alive P =.002). CONCLUSION The Q-TWiST analysis is a powerful decision aid in choosing among alternative therapies. Prospective information on patient preferences will facilitate future trials evaluating treatment outcomes. Refinements in the Q-TWiST method could be included to further enhance the power of this patient care decision-making tool.

Abstract
To determine whether patients with a HLA-identical sibling donor have a better outcome than patients without a donor, an analysis on the basis of intention-to-treat principles was performed within the framework of the EORTC-GIMEMA randomized phase III AML 8A trial. Patients in complete remission (CR) received one intensive consolidation course. Patients with a histocompatible sibling donor were then allocated allogeneic bone marrow transplantation (alloBMT), the patients without a donor were randomized between autologous BMT (ABMT) and a second intensive consolidation (IC2). 831 patients <46 years old and alive >8 weeks from diagnosis were included. HLA typing was performed in 672 patients. AlloBMT was performed during CR1 in 180 (61%) out of 295 patients with a donor. Another 38 patients were allografted: five in resistant disease, 14 during relapse and 19 in CR2. ABMT was performed in 130 (34%) out of 377 patients without a donor in CR1, in six (2%) patients during relapse and in 38 (10%) patients during CR2. The disease-free survival (DFS) from CR for patients with a donor was significantly longer than for patients without a donor (46% v 33% at 6 years; P=0.01, RR 0.78, 95% confidence interval 0.63-0.96). The overall survival from diagnosis for patients with a donor was longer, but not statistically significant, than for patients without a donor (48% v 40% at 6 years; logrank P=0.24). When patients were stratified according to prognostic risk groups, the same trend in favour of patients with a donor was seen for survival duration and the DFS remained significantly longer for this group of patients.

Abstract
BACKGROUND Three strategies are used to prevent relapse in patients with acute myeloid leukaemia in first remission. Most of those with suitable donors are offered allogeneic haemopoietic-stem-cell transplant. Other patients may receive intensive chemotherapy or autologous transplantation; we undertook this randomised prospective trial to assess which is the better option. METHODS After three courses of intensive chemotherapy, bone marrow was harvested from patients (<56 years of age) in remission who lacked an HLA-matched sibling donor. These patients were then randomised to receive, after one more course of chemotherapy, no further treatment (n=191) or an autologous bone-marrow transplant (BMT) after preparation with cyclophosphamide and total-body irradiation (n=190). Outcome comparisons were by intention to treat with adjustment for the most important risk factors for relapse. FINDINGS 381 patients were randomised (38% of those eligible). Of the 190 patients allocated autologous BMT, 126 received it. On intention-to-treat analysis the number of relapses was substantially lower in the autologous BMT group than in the group assigned no further treatment (64/190 [37%] vs 101/191 [58%], p=0.0007), resulting in superior disease-free survival at 7 years (53 vs 40%; p=0.04). These benefits were observed in all risk groups and age-groups. There were more deaths in remission in the autologous BMT group than in the no further treatment group (22 [12%] vs 7 [4%], p=0008). In children (<15 years) and patients with good-risk disease, survival from relapse in the no further treatment group was 35% and 38% at 2 years. There was an overall survival advantage in the autologous BMT group at 7 years (57 vs 45%, p=0.2). INTERPRETATION The addition of autologous BMT to four courses of intensive chemotherapy substantially reduces the risk of relapse in all risk groups, leading to improvement in long-term survival. The good chance of salvage for children or patients with good-risk disease who relapse from chemotherapy, and the mortality, morbidity, late effects, and expense of autologous BMT, suggest that delay of autograft until second remission in these two groups may be appropriate.

Abstract
The destruction of hematopoiesis and lymphopoiesis by total body irradiation or high dose chemotherapy for the treatment of malignancy can be reversed by the transplantation of allogeneic or autologous hematopoietic stem cells. In primary disorders of bone marrow or immune system, allogeneic stem cells replace deficient cells. Acute leukemias can be cured, with in 50 to 80% disease free survival after 5 to 8 years. The allogeneic graft versus leukemia effect by immunoreactive cells reduces the relapse rate in myeloid and lymphoid malignancies. 40 to 70% of patients with chronic myeloid leukemia remain disease free after more than 5 years. Patients with malignant lymphoma have a 40 to 70% chance of cure with autologous transplantation, which is not increased by allogeneic cells, because of a higher incidence of severe complications. An increasing number of patients without option for cure is treated with the aim of prolonging remission or retarding disease progression, such as in chronic myeloid leukemia, multiple myeloma and certain solid tumors. New studies suggest in breast cancer with axillary lymph node metastases, that adjuvant high dose chemotherapy with autologous stem cell support will significantly improve disease free survival from 30 to over 60% after 3 to 5 years. In congenital metabolic and storage diseases deficient enzymes are substituted by the allogeneic cells. Clinical trials explore the use of stem cell transplantation after myeloablative therapy in autoimmune disorders as well as in gene therapy with transfected hematopoietic stem cells.

Abstract
We report the outcome of 50 consecutive patients with CR1 acute leukemia (AML = 22; ALL = 28) treated with autologous BMT, after cyclophosphamide and TBI, followed with a sequential high dose rIL2 regimen. rIL-2 (RU 49637 from Roussel-Uclaf, Romainville, France) was started after hematological reconstitution an average of 72 +/- 22 days post transplant. The schedule consisted of a continuous infusion over 5 cycles (Cycle 1: 5 days starting on day 1; cycle 2-5: 2 days starting on day 15, 29, 43 and 57). Patients were treated at 4 different dosages (12 (N = 40), 16 (N = 3), 20 (N = 2), 24 (N = 5) x 10(6) IU/m2/day). Toxicities were mainly related to capillary leak syndrome and thrombocytopenia. Patients received an average of 122 +/- 49 10(6) IU/m2. Two patients with AML died from toxicity. rIL-2 infusion was associated with very a high level of immune stimu-lation of both T-cells (P < 0.05) and natural killer (NK) cells (P < 0.05) and associated cytolytic functions (P < 0.05). With a minimal and median follow-up of 21 and 46 months, 3 year leukemia free survival is 41 +/- 6% overall, 39 +/- 10% and 43 +/- 8% for AML and ALL respectively. Relapse probabilities at 3 years are 59 +/- 11% for AML and 57 +/- 8% for ALL. We conclude that this short infusion of rIL-2 over 2 months, resulting in an increased immune stimulation, is not associated with a better leukemic control for patients with acute leukemia transplanted early after reaching first complete remission.

Abstract
Untreated acute leukemia is a uniformly fatal disease with a median survival time shorter than 3 months. Current treatment strategies provide a significant increase in survival time for most patients, some of whom may be cured. The majority of patients with acute leukemia, however, ultimately die of the disease or complications of treatment. The effective treatment of acute leukemia requires (1) differentiation of acute myeloid leukemia (AML) from acute lymphoblastic leukemia (ALL) and recognition of clinically relevant subtypes; (2) identification of patients who are more likely or less likely than average to benefit from a conventional treatment; and (3) selection of therapy that provides a reasonable likelihood of response with acceptable risk of toxic effects. The diagnosis of acute leukemia is established in most cases by a bone marrow aspirate that demonstrates at least 30% blast cells. The traditional criteria to distinguish between AML and ALL rely on morphology and cytochemical reactions. Immunologic analysis of antigen expression and analysis for numerical or structural chromosomal abnormalities of leukemia cells are routinely feasible. Karyotypic analysis is of prognostic importance and should be performed on all diagnostic specimens of bone marrow aspirate. Immunophenotypic analysis may be useful to confirm the disease classification in selected cases. The importance of the routine immunophenotypic characterization of acute leukemia, however, is controversial. The subtypes that must be recognized because of the need for specific treatment include (a) acute promyelocytic leukemia (APL), which is the M3 subtype of AML, and (b) the L3 subtype or mature B-cell ALL. Induction therapy for acute leukemia is treatment intended to achieve induction of complete remission (CR). Complete remission is defined as the absence of morphologic evidence of leukemia after recovery of the peripheral blood cell counts. Failure to achieve CR may be attributed to death during chemotherapy-induced bone marrow hypoplasia or to drug resistance manifested either as failure to achieve hypoplasia or as persistent leukemia after recovery from hypoplasia. Postremission therapy is treatment administered in CR to prevent or delay relapse of the leukemia. However, the majority of patients have disease relapse. Intensification of therapy is a treatment strategy designed to overcome resistance to chemotherapy. Recent clinical trials of intensified induction or postremission therapy suggest improved outcome. However, the toxic effects of dose intensification can be substantial, limiting any potential benefit of this approach. Identification of prognostic factors may allow one to estimate the likelihood of an outcome, to determine an optimal treatment strategy. It is well established that age at the time of diagnosis, leukemia cell karyotype, and whether the leukemia is de novo or secondary are factors that influence treatment decisions. Patients with favorable prognostic factors should probably receive conventional therapy. Patients with unfavorable prognostic factors have shown little benefit from conventional therapy. In addition, factors that indicate poor outcome with conventional therapy are also predictive of poor outcome with intensified therapy. Consequently, these patients should be considered for investigational therapeutic strategies. The bias may be to counsel them to accept the potential increased morbidity of such treatment before there is definite evidence of the possibility of improved outcome. Induction chemotherapy for younger patients with AML (less than 55 years of age) in general consists of one or more courses of cytarabine (ara-C) and an anthracycline or an anthracycline derivative. Randomized trials have failed to confirm that treatment with either etoposide or high-dose ara-C induces disease remission. Patients with secondary AML, high levels of CD34 antigen expression, or an unfavorable karyotype, however, may benefit from ind

Abstract
The best therapy for people with acute myelogenous leukemia (AML) in first remission is controversial. Options include postremission chemotherapy, a bone marrow transplant (HLA-identical sibling or autotransplant) or chemotherapy followed by a transplant at relapse. Four large cooperative group trials address this issue. In this review design and implementation of these trials is considered. Whether data from these trials will answer the questions of the best therapy for AML in first remission, is focused upon.

Abstract
Hematopoiesis after autologous bone marrow transplantation (BMT) is characterized by a prolonged and severe deficiency of marrow progenitors for several years, especially of erythroid and megakaryocyte progenitors, while the peripheral blood cells and marrow cellularity have reached relatively normal values within a few weeks. These anomalies are comparable to those reported for allogeneic BMT, despite the absence of any allo-immune reaction or post-graft immunosuppressive therapy. Post-graft hematopoietic impairment is the consequence of quantitative and qualitative changes involving both stem cell and stromal compartments which are expressed by an impaired capacity of stem cell self-renewal and commitment towards erythroid and megakaryocytic lineages. Besides the toxicity of conditioning regimens, hematopoietic reconstitution using autologous grafts is particularly dependent on a combination of factors related to the patient, such as underlying disease and pre-graft chemotherapy regimens, and to the graft processing itself, such as in vitro purging with chemotherapeutic agents.

Abstract
Twenty-three patients with acute myelogenous leukemia (AML) in first relapse were treated with high-dose cytosine-arabinoside (Ara-C) and amsacrine or idarubicin. To prime the cells, the patients were given rhGM-CSF. We studied the influence of 48-h infusion of rhGM-CSF on proliferation and Ara-C sensitivity of leukemic cells both ex vivo and in vitro. We found that a 48-h infusion of rhGM-CSF increased both white blood cell counts and peripheral blood blast cell percentages. Using a Bromodeoxyuridine/DNA (BrdUrd/DNA) staining in flow cytometry, we found an non-constant increase in cells in the S-phase. Ex vivo 48-h culture of leukemic cells with or without rhGM-CSF, with or without other hematopoietic growth factors (HGFs), showed a greater increase of the cells in the S-phase with GF but no correlation with the ex vivo results. We used a method of quantitation of the DNA synthesis previously described (Lacombe F., et al. (1992) Cytometry 13, 730) to monitor the Ara-C sensitivity of the cells in S-phase before and after 48-h infusion with rhGM-CSF. We observed a great variation in the Ara-C sensitivity of the leukemic cells before and after infusion with rhGM-CSF from one patient to another. The BrdUrd/DNA method seems a convenient method to study the influence of HGFs on Ara-C sensitivity of the patients.

Abstract
BACKGROUND The value of autologous bone marrow transplantation in the treatment of children with acute myeloid leukemia (AML) is unknown. We compared autologous bone marrow transplantation with intensive consolidation chemotherapy as treatments for children with AML in first remission. METHODS We induced remission with one course of daunorubicin, cytarabine, and thioguanine, followed by one course of high-dose cytarabine (3 g per square meter of body-surface area for six doses). Patients in remission after the second course of induction therapy were eligible for randomization. Between June 1988 and March 1993, 552 of 649 enrolled patients who could be evaluated (85 percent) entered remission. A total of 209 patients were not eligible for randomization; of the remaining 343 patients, 232 were randomly assigned to receive six courses of intensive chemotherapy (117 patients) or autologous transplantation (115 patients). Of the original 649 patients, 189, including 21 with Down's syndrome, were nonrandomly assigned to receive intensive chemotherapy. RESULTS The rates of event-free survival and overall survival for the entire group at three years were 34 +/- 2.5 percent and 42 +/- 2.6 percent, respectively. For patients who were randomly assigned to one of the two treatment groups, the mean (+/- SE) rates of event-free survival three years after randomization were not significantly different in the two groups when examined by intention-to-treat analysis: 36 +/- 5.8 percent for the intensive-chemotherapy group as compared with 38 +/- 6.4 percent for the autologous-transplantation group; and the relative risk of treatment failure for the chemotherapy group as compared with the autologous-transplantation group was 0.81 (P = 0.20 by the log rank test; 95 percent confidence interval, 0.58 to 1.12). Overall survival at three years followed a similar pattern. There was a lower relapse rate (31 percent vs. 58 percent, P < 0.001) but a higher rate of treatment-related mortality (15 percent vs. 2.7 percent, P = 0.005) in the group treated with autologous transplantation than in the intensive-chemotherapy group. The event-free survival at three years for the nonrandomized intensive-chemotherapy group was 39 +/- 5.1 percent, and for a contemporaneous group of patients each of whom received a histocompatible bone marrow transplant from a sibling, it was 52 +/- 8.0 percent. CONCLUSIONS Treatment of children with AML in first remission with either autologous bone marrow transplantation or intensive chemotherapy prolongs event-free survival equally.

Abstract
Current induction chemotherapy regimens afford a complete remission in 60 to 80% of patients less than 60 years of age who are diagnosed with acute myelogenous leukaemia. Patients who undergo consolidation with high dose Ara-C or with autologous or allogeneic bone marrow transplantation can expect a long-term disease free survival of 30 to 45%. Which mode of consolidation is preferable is still being investigated in randomized studies. Many disease characteristics have been put forward as prognostic variables in treatment outcome and as understanding of the biology of AML has continued to expand, cytogenetic and molecular markers have assumed greater importance in disease characterization, but the ultimate role that these play in prognosis remains incompletely defined. Once AML has relapsed, bone marrow transplantation may result in prolonged disease free survival as compared to use of salvage chemotherapy regimens. Because the long-term survival of all patients diagnosed with AML is only in the order of 10 to 20%, new treatment approaches to this disease are required. Current clinical and research efforts have focused on modulation of the immune system, modulation of drug resistance phenotypes, and understanding of the response of leukaemic cells to haematopoietic growth factors.

Abstract
Despite progress over the past three decades, most patients with acute myeloid leukemia (AML) treated with conventional chemotherapy alone relapse and die of recurrent leukemia. Treatments used to improve outcome include allogeneic (alloBMT) and autologous bone marrow transplantation (ABMT). Indications for transplantation and the relative merits of alloBMT and ABMT remain unclear. In this review, we evaluate evidence supporting a role of ABMT in AML and compare the results with outcomes after alloBMT. In addition, we discuss areas of controversy including the optimal timing for ABMT, the role of bone marrow purging, the place of peripheral blood stem cell collection, the high dose regimen, and post-transplant immunotherapy to reduce relapse.

Abstract
BACKGROUND Allogeneic or autologous bone marrow transplantation and intensive consolidation chemotherapy are used to treat acute myelogenous leukemia in a first complete remission. METHODS After induction treatment with daunorubicin and cytarabine, patients who had a complete remission received a first course of intensive consolidation chemotherapy, combining intermediate-dose cytarabine and amsacrine. Patients with an HLA-identical sibling were assigned to undergo allogeneic bone marrow transplantation; the others were randomly assigned to undergo autologous bone marrow transplantation (with unpurged bone marrow) or a second course of intensive chemotherapy, combining high-dose cytarabine and daunorubicin. Comparisons were made on the basis of the intention to treat. RESULTS A total of 623 patients had a complete remission; 168 were assigned to undergo allogeneic bone marrow transplantation, and 254 were randomly assigned to one of the other two groups. Of these patients, 343 completed the treatment assignment: 144 in the allogeneic-transplantation group, 95 in the autologous-transplantation group, and 104 in the intensive-chemotherapy group. The relapse rate was highest in the intensive-chemotherapy group and lowest in the allogeneic-transplantation group, whereas the mortality rate was highest after allogeneic transplantation and lowest after intensive chemotherapy. The projected rate of disease-free survival at four years was 55 percent for allogeneic transplantation, 48 percent for autologous transplantation, and 30 percent for intensive chemotherapy. However, the overall survival after complete remission was similar in the three groups, since more patients who relapsed after a second course of intensive chemotherapy had a response to subsequent autologous bone marrow transplantation. Other differences were also observed, especially with regard to hematopoietic recovery (it occurred later after autologous transplantation) and the duration of hospitalization (it was longer with bone marrow transplantation). CONCLUSIONS Autologous as well as allogeneic bone marrow transplantation results in better disease-free survival than intensive consolidation chemotherapy with high-dose cytarabine and daunorubicin. Transplantation soon after a relapse or during a second complete remission might also be appropriate.

Abstract
The DNR accumulation (DNR Acc) and the verapamil (VRP) index (percent increase of VRP on DNR accumulation) was studied by using flow cytometry. Fresh leukemic mononuclear bone marrow blasts from 80 unselected ANLL patients' samples were incubated with DNR in the presence or absence of VRP. The DNR accumulation was determined by flow cytometry. The median DNR Acc was 28 (range: 4-101) and the median VRP index was 4% (range 0-53). VRP significantly enhanced DNR Acc in 42 of the ANLL samples (52.5%). DNR Acc or VRP index were not influenced by age, sex, or WBC counts. Only the FAB subclassification and the blast immunophenotyping were found to influence the parameters studied here. The lowest DNR Acc was found in M0 and M6 blast cells (15 range 0-46 and 10.5 range 8-13 respectively). M4 and M5 ANLL samples accumulated significantly more DNR than M0 and M6 blast cells. The VRP index was significantly higher in M0 compared with M1 and M2 samples, as well as in M4 compared with M1 samples. A slightly positive correlation was found between the percentage of CD34-positive cells in the CD34-positive samples and DNR Acc. In this study, DNR Acc and the VRP index were not significantly correlated with the response to chemotherapy or survival. In conclusion, this study shows that ANLL leukemic cells differ in anthracyclin accumulation and response to VRP in vitro.

Abstract
From highly investigational to standardized therapy, allogeneic BMT has established its role in the treatment of selected diseases. Continued refinements in bone marrow transplantation will increase the number of potential candidates, reduce associated risks, and improve disease-free survival rates. With further exploration into its efficacy, allogeneic BMT will bring new challenges and opportunities for patients, families, and health care providers.

Abstract
The direct and indirect costs of acute myeloid leukemia were estimated for Sweden in 1989. The calculated total cost was SEK 460 million. Nearly half of the costs, or 1.7 million per patient diagnosed, were indirect costs due to premature mortality. Direct costs of relapses and indirect costs of mortality represent costs due to the absence of completely curable therapy. They also represent potential cost savings that could be obtained after introduction of new treatment options in the future.
