Abstract
Aim: To compare all-cause and acute lymphoblastic leukemia (ALL)-related healthcare resource utilization (HCRU) and costs among patients receiving inotuzumab ozogamicin (InO) and blinatumomab (Blina) for ALL in the first relapsed/refractory (R/R) setting. Patients & methods: We studied retrospective claims for adult commercial and Medicare Advantage enrollees with ALL receiving InO (n = 29) or Blina (n = 23) from 1 January 2015 to 16 February 2021. Mean per-patient-per-month (PPPM) HCRU and total costs were described and multivariable-adjusted PPPM total all-cause and ALL-related predicted costs were calculated. Results: Mean monthly ALL-related hospitalizations were the same for patients receiving InO and Blina (PPPM = 0.8 stays); however, the length of ALL-related hospital stay was almost twice as long among patients receiving Blina versus InO (ALL-related: InO = 7.6 days; Blina = 14.1 days; p = 0.346). In multivariable models, total ALL-related costs were 43% lower for InO compared with Blina (PPPM costs: InO = $93,767; Blina = $163,470; p = 0.021). Conclusion: In the first R/R setting, patients who used InO had significantly lower all-cause and ALL-related costs compared with patients who used Blina, in part driven by hospitalization patterns.

Clonal hematopoiesis of indeterminate potential and its impact on patient trajectories after stem cell transplantation. PLoS Comput Biol 2019; 15:e1006913.

Abstract
Clonal hematopoiesis of indeterminate potential (CHIP) is a recently identified process where older patients accumulate distinct subclones defined by recurring somatic mutations in hematopoietic stem cells. CHIP's implications for stem cell transplantation have been harder to identify due to the high degree of mutational heterogeneity that is present within the genetically distinct subclones. In order to gain a better understanding of CHIP and the impact of clonal dynamics on transplantation outcomes, we created a mathematical model of clonal competition dynamics. Our analyses highlight the importance of understanding competition intensity between healthy and mutant clones. Importantly, we highlight the risk that CHIP poses in leading to dominance of precancerous mutant clones and the risk of donor derived leukemia. Furthermore, we estimate the degree of competition intensity and bone marrow niche decline in mice during aging by using our modeling framework. Together, our work highlights the importance of better characterizing the ecological and clonal composition in hematopoietic donor populations at the time of stem cell transplantation.

Autologous stem cell transplantation for adult acute leukemia in 2015: time to rethink? Present status and future prospects. Bone Marrow Transplant 2015; 50:1495-502.

Abstract
The use of autologous stem cell transplantation (ASCT) as consolidation therapy for adult patients with acute leukemia has declined over time. However, multiple randomized studies in the past have reported lower relapse rates after autologous transplantation compared with chemotherapy and lower non-relapse mortality rates compared with allogeneic transplantation. In addition, quality of life of long-term survivors is better after autologous transplantation than after allogeneic transplantation. Further, recent developments may improve outcomes of autograft recipients. These include the use of IV busulfan and the busulfan+melphalan combination, better detection of minimal residual disease (MRD) with molecular biology techniques, the introduction of targeted therapies and post-transplant maintenance therapy. Therefore, ASCT may nowadays be reconsidered for consolidation in the following patients if and when they reach a MRD-negative status: good- and at least intermediate-1 risk acute myelocytic leukemia in first CR, acute promyelocytic leukemia in second CR, Ph-positive acute lymphocytic leukemia. Conversely, patients with MRD-positive status or high-risk leukemia should not be considered for consolidation with ASCT.

Abstract
Adult patients with acute leukemia in need of a transplant but without a genoidentical donor are usually considered upfront for transplantation with stem cells from any other allogeneic source, rather than autologous stem cell transplantation. We used data from the European Society for Blood and Marrow Transplantation and performed a matched pair analysis on 188 T-cell-replete haploidentical and 356 autologous transplants done from January 2007 to December 2012, using age, diagnosis, disease status, cytogenetics, and interval from diagnosis to transplant as matching factors. "Haploidentical expert" centers were defined as having reported more than five haploidentical transplants for acute leukemia (median value for the study period). The median follow-up was 28 months. Multivariate analyses, including type of transplant categorized into three classes ("haploidentical regular", "haploidentical expert" and autologous), conditioning intensity (reduced intensity versus myeloablative conditioning) and the random effect taking into account associations related to matching, showed that non-relapse mortality was higher following haploidentical transplants in expert (HR: 4.7; P=0.00004) and regular (HR: 8.98; P<10(-5)) centers. Relapse incidence for haploidentical transplants was lower in expert centers (HR:0.39; P=0.0003) but in regular centers was similar to that for autologous transplants. Leukemia-free survival and overall survival rates were higher following autologous transplantation than haploidentical transplants in regular centers (HR: 1.63; P=0.008 and HR: 2.31; P=0.0002 respectively) but similar to those following haploidentical transplants in expert centers. We conclude that autologous stem cell transplantation should presently be considered as a possible alternative to haploidentical transplantation in regular centers that have not developed a specific expert program.

Abstract
OBJECTIVE To evaluate the efficacy and toxicity of autologous hematopoietic stem cell transplantation (AHSCT) for high-risk acute lymphoblastic leukemia (ALL). MATERIAL AND METHODS Overall, 128 high-risk ALL patients at a median age of 26 years (range 18-56 years) at diagnosis received AHSCT between 1991-2008. Induction treatment was anthracycline-based in all patients. Conditioning regimen consisted of CAV (cyclophosphamide, cytarabine, etoposide) in 125 patients whereas 3 subjects received cyclophosphamide and TBI (total body irradiation). Bone marrow was stored for 72 hours in 4°C and re-infused 24 hours after conditioning completion. Bone marrow was a source of stem cells in 119 patients, peripheral blood in 2 and 7 subjects received both bone marrow and peripheral blood. RESULTS With a median follow-up after AHSCT of 1.6 years (range 0.1-22.3 years), the probability of leukemia-free survival (LFS) for the whole group at 10 years was 27% and 23% at 20 years. Transplant-related mortality at 100 days after AHSCT was 3.2%. There was a strong tendency for better LFS for MRD-negative patients if compared with patients who had positive or unknown MRD status at AHSCT (32% vs 23% and 25%, respectively; p=0.06). There was no difference in LFS between B- and T-lineage ALL as well as between patients transplanted in first complete remission (CR1) and CR2. LFS at 10 years for patients with Philadelphia-positive (Ph+) ALL at transplant was 20% and this was comparable with subjects with negative and missing Ph status (26% and 28%; p=0.97). CONCLUSIONS The results of AHSCT for high-risk ALL remains unsatisfactory with low probability of long-term LFS.

Abstract
Escape of apoptosis may contribute to treatment failure in childhood acute lymphoblastic leukemia (ALL) calling for new approaches to overcome apoptosis resistance. Here, we provide for the first time evidence that small molecule inhibitors that target the anti-apoptotic protein X-linked inhibitor of apoptosis (XIAP) sensitize ALL cells for CD95-induced apoptosis. XIAP inhibitors at subtoxic concentrations, but not a structurally related control compound, act synergistically with agonistic anti-CD95 antibodies or MegaFasL, a hexameric form of CD95 ligand, to induce apoptosis in ALL cells. Further, XIAP inhibitors co-operate with MegaFasL to reduce clonogenic survival of ALL cells demonstrating their effect also on long-term survival. In contrast, XIAP inhibitors show little effect on MegaFasL-mediated apoptosis in normal peripheral blood lymphocytes (PBLs), pointing to some tumor selectivity. Molecular studies reveal that XIAP inhibitors enhance CD95-induced activation of caspases, loss of mitochondrial membrane potential and cytochrome c release in a caspase-dependent manner. Importantly, XIAP inhibitors sensitize primary leukemic blasts from children with ALL for MegaFasL-induced apoptosis. Thus, small molecule XIAP inhibitors present a promising novel approach to enhance CD95-induced apoptosis in childhood acute leukemia.

Abstract
AbstractThe decision to proceed to transplant for adult patients with acute lymphoblastic leukemia (ALL) is not clear-cut. Relapse and nonrelapse mortality continue to plague the outcome of hematopoietic stem cell transplantation (HSCT) even when undertaken in complete remission (CR). Those considered to be at high risk for relapse often are considered for HSCT in first complete remission (CR1) while those at lower risk may not be referred until they have relapsed, when their chances for cure are very poor. In some patients who have a suitable histocompatible sibling, disease- or patient-related factors may override the potential benefit of allogeneic HSCT. Because many patients do not have a suitable histocompatible sibling, one has to consider the relative merits of autologous transplantation versus use of an alternative allogeneic stem cell source, such as a matched-unrelated donor (MUD), umbilical cord blood (UCB) donor, or haploidentical donor. Deciding among these options in comparison to chemotherapy even in high-risk patients is difficult. In the review, the risks and benefits of these choices are discussed to determine whether and by what means to proceed to HSCT in adult patients with ALL who are in CR1. Presented are two patients with ALL and a discussion of how the data we provide would lead to a decision about the selection of therapy.

Abstract
Long-term disease-free survival (DFS) has been reported after autologous stem cell transplantation for acute lymphoblastic leukemia. Phase II studies have evaluated its role in first and subsequent complete remission (CR) with DFS rates of up to 50%. It has been under-utilized in 1st CR in part, due to a concern that patients who relapse after autologous stem cell transplantation (ASCT) have fewer options for salvage treatment of relapsed disease. Unfortunately, survival rates of <5% are reported in patients who relapse, regardless of initial therapy. Few prospective, randomized trials have analyzed large enough numbers of patients to allow us to determine the appropriate patient population for autologous transplantation. Although variability in the available studies makes it difficult to draw a definite conclusion, and many issues remain unresolved, available data suggests that there may be a group of patients for whom ASCT in first remission is a reasonable and perhaps superior treatment choice. Factors such as risk features at diagnosis, and minimal residual disease following induction therapy greatly affect outcome following ASCT. The available data as well as the questions that remain to be answered will be discussed and reviewed.

Abstract
A nationwide survey of hematopoietic cell transplantation (HCT) was started in Japan in 1991, and the analyzed survey data have been presented as the annual report of the Japan Society for Hematopoietic Cell Transplantation. The 10-year overall survival (OS) rates after HCT for each disease are as follows: acute myelogenous leukemia, 44.2%; acute lymphocytic leukemia, 33.7%; adult T-cell leukemia, 24.6%; chronic myelogenous leukemia, 53.3%; myelodysplastic syndrome, 37.3%; non-Hodgkin's lymphoma, 41.5%; Hodgkin's lymphoma, 50.8%; aplastic anemia, 72.5%; breast cancer, 37.1%; germ cell tumor, 52.6%; and ovarian cancer, 44.2%. The 5-year OS rates for multiple myeloma and lung cancer were 40.6% and 23.6%, respectively. Except in cord blood transplantation, engraftment was accomplished in more than 90% of patients. The respective frequencies of acute graft-versus-host disease (GVHD) and chronic GVHD were 41.1% and 34.9% for related bone marrow transplantation (BMT), 66.8% and 34.5% for unrelated BMT, 52.9% and 36.0% for allogeneic peripheral blood stem cell transplantation, and 53.3% and 32.1% for allogeneic cord blood transplantation. OS for each disease was analyzed by patient age, stem cell source, donor type, disease status, and disease type. These data provide objective and valuable information for hematologists as well as for patients who need HCT.

Abstract
BACKGROUND The prognosis for adult patients with acute lymphoblastic leukemia (ALL) remains unsatisfactory primarily because of the high incidence of recurrence. Therefore, optimal postremission therapy is a matter of vital concern. In particular, the clinical efficacy of allogeneic hematopoietic stem cell transplantation (HSCT) should be clarified. METHODS Rigorous criteria were used to select 7 studies of adult ALL that prospectively assessed overall survival (OS) using natural randomization based on donor availability combined with intention-to-treat analyses. The authors then performed a metaanalysis to evaluate the role of allogeneic HSCT. RESULTS Seven studies that included 1274 patients were selected. A metaanalysis demonstrated that patients in the donor groups had significantly better survival than patients in the no-donor groups (hazard ratio [HR], 1.29; 95% confidence interval [95% CI], 1.02-1.63 [P = .037]). When only high-risk patients were included in the analysis, the superiority of the survival advantage was even greater (HR, 1.42; 95% CI, 1.06-1.90 [P = .019]). A meta-regression analysis revealed that compliance with allogeneic HSCT showed a significant and positive correlation with survival (coefficient, 0.022; P < .01), suggesting that the greater the proportion of patients who actually received allogeneic HSCT, the better the survival of the donor group. No beneficial effects of autologous HSCT were observed. CONCLUSIONS The current findings demonstrated that allogeneic HSCT improves the outcome of adult patients with high-risk ALL. Although these analyses were based on abstracted data, the results indicated that allogeneic HSCT should be considered for such patients if a suitable donor is available.

Abstract
Dose-escalated chemotherapy has proven utility in a variety of treatment settings, including preparative regimens before bone marrow or hematopoietic stem cell transplantation. However, the potential damage imposed by aggressive regimens on the marrow microenvironment warrants further investigation. In the present study, we tested the hypothesis that dose-escalated chemotherapy, with etoposide as a model chemotherapeutic agent, activates the transforming growth factor beta-1 (TGF-beta1) signaling pathway in bone marrow stromal cells. After high-dose etoposide exposure in vitro, Smad3 protein was phosphorylated in a time-and dose-dependent manner in marrow-derived stromal cells, coincident with the release of active and latent TGF-beta1 from the extracellular matrix. Phosphorylation was modulated by p38 kinase, with translocation of Smad3 from the cytoplasm to the nucleus subsequent to its phosphorylation. Etoposide induced activation of TGF-beta1 followed the generation of reactive oxygen species and required matrix metalloproteinase-2 (MMP-2) protein availability. Chemotherapy effects were diminished in MMP-2(-/-) knockout stromal cells and TGF-beta1 knockdown small interfering RNA-transfected stromal cells, in which phosphorylation of Smad3 was negligible after etoposide exposure. Stable transfection of a human MMP-2 cDNA into bone marrow stromal cells resulted in elevated phosphorylation of Smad3 during chemotherapy. These data suggest TGF-beta1/p38/Smad3 signaling cascades are activated in bone marrow stromal cells after dose-escalated chemotherapy and may contribute to chemotherapy-induced alterations of the marrow microenvironment.

Abstract
Acute lymphoblastic leukaemia (ALL) in adults is a relatively rare neoplasm with a curability rate around 30% at 5 years. This consideration makes it imperative to dissect further the biological mechanisms of disease, in order to selectively implement an hitherto unsatisfactory success rate. The recognition of discrete ALL subtypes (some of which deserve specific therapeutic approaches, like T-lineage ALL (T-ALL) and mature B-lineage ALL (B-ALL)) is possible through an accurate combination of cytomorphology, immunophenotytpe and cytogenetic assays and has been a major result of clinical research studies conducted over the past 20 years. Two-three major prognostic groups are now easily identifiable, with a survival probability ranging from <10 to 20% (Philadelphia-positive ALL) to about 50-60% (low-risk T-ALL and selected patients with B-lineage ALL). These issues are extensively reviewed and form the basis of current knowledge. The second major point relates to the emerging importance of studies that reveal a dysregulated gene activity and its clinical counterpart. It is now clear that prognostication is a complex matter ranging from patient-related issues to cytogenetics to molecular biology, including the evaluation of minimal residual disease (MRD) and possibly gene array tests. On these bases, the role of a correct, highly personalised therapeutic choice will soon become fundamental. Therapeutic progress may be obtainable through a careful integration of chemotherapy, stem cell transplantation, and the new targeted treatments with highly specific metabolic inhibitors and humanised monoclonal antibodies.

Abstract
In 1402 patients allografted in Europe during the period 1990-2000 with an HLA-identical sibling in first remission (CR1), the median interval from CR1 to allotransplant (96 days) was a major prognostic factor, patients transplanted earlier having a worse outcome. We studied in depth the 414 fully evaluable patients transplanted less than 96 days after achieving CR1; in these patients, only three factors predicted for the outcome by multivariate analysis: patient age, CR1 achievement with one or more induction courses and the recipient/donor sex combination. These three factors overcame the information from cytogenetics and source of stem cells. Three prognostic groups could be identified in relation to the outcome, using a prognostic score affecting 1 to each poor risk factor (total from 0 to 3): Group 1 (good prognosis) includes patients <35 years old, achieving CR1 with one induction course and to be transplanted with any other sex combination than female to male (score 0); group 2 (intermediate) with one adverse factor (score 1); and group 3 (bad prognosis) with two or three adverse criteria (scores 2 and 3). In these three groups, the 3-year leukaemia-free survival was 56+/-5%, 48+/-4% and 29+/-4% and the overall survival was 65+/-5, 53+/-4 and 29+/-5%, respectively. Therefore, adult patients with ALL and a score of 0 or 1 are good candidates for an early transplant if they have an identical sibling donor. Patient age, response to induction and the sex of the HLA-identical family donor (if existing) are the strongest easy predictors of the outcome for an early transplant in an adult patient with ALL. No additional information is mandatory.

Abstract
OBJECTIVES To review the current evidence regarding the role and benefits of hematopoietic cell transplantation (HCT) in leukemia. DATA SOURCES Review articles, original articles, internet web sites, and books. CONCLUSION HCT is a potentially curative treatment modality for patients with hematologic malignancies such as leukemia. IMPLICATIONS FOR NURSING PRACTICE Nurses working with patients undergoing HCT need awareness of the type of leukemia, source of the hematopoietic cell product, type of preparative regimen used, and the complications of the procedure will enable nurses to educate and intervene with patients and their family members throughout the transplant trajectory.
