Effects of different types of allogeneic hematopoietic stem cell transplantation donors on Philadelphia chromosome-positive acute lymphoblastic leukemia during the tyrosine kinase inhibitor era: A systematic review and meta-analysis. Hematol Oncol Stem Cell Ther 2023; 16:197-208.

Abstract
BACKGROUND Matched donor (MD) allogeneic hematopoietic stem cell transplantation (allo-HSCT) is currently the preferred choice of treatment for Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) patients who have achieved complete remission. This systematic review and meta-analysis was conducted to investigate the effects of allo-HSCTs from different donor types for Ph+ ALL patients who received tyrosine kinase inhibitors (TKIs). METHODS Studies in EMBASE and MEDLINE between inception and December 2020 were identified using search terms related to "Ph+ ALL" and "HSCT." Eligible studies were studies with Ph+ ALL patients who received a TKI and allo-HSCT. The primary outcomes of interest-the overall survival (OS) or relapse-free survival (RFS)-needed to be reported. The Mantel-Haenszel method was used to combine the effect estimates and associated 95% confidence intervals (CIs) of each donor type. RESULTS Fourteen cohort studies were identified for the meta-analysis. Haploidentical (HID)-HSCT for Ph+ ALL patients resulted in a superior RFS to MD-HSCT, with a pooled odds ratio (OR) of 1.57 (95% CI, 1.05-2.32; I2 = 0%). However, HID-HSCT and MD-HSCT had comparable OS. Furthermore, HID-HSCT group had a significantly lower relapse rate than MD-HSCT group. On the other hand, the risks of graft-versus-host disease (GvHD) were higher for HID-HSCT and pooled OR of chronic GvHD rate. The OS and RFS of matched sibling-HSCT, matched unrelated-HSCT, and cord blood-HSCT were comparable with those of HID-HSCT. CONCLUSION This systematic review and meta-analysis showed that HID-HSCT is as effective as MD-HSCT in Ph+ ALL patients.

Safety and outcomes of maintenance therapy with third-generation tyrosine kinase inhibitor after allogeneic hematopoietic cell transplantation in Philadelphia chromosome positive acute lymphoblastic leukemia patients with T315I mutation. Leuk Res 2022; 121:106930. [PMID: 36007342 DOI: 10.1016/j.leukres.2022.106930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 06/26/2022] [Accepted: 08/15/2022] [Indexed: 11/30/2022]
Abstract
Studies using third-generation tyrosine kinase inhibitor (TKI) as maintenance therapy after hematopoietic cell transplantation (HCT) for patients with Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ALL) harboring the T315I mutation remain scarce. We conducted a cohort study to evaluate the safety and outcomes of ponatinib maintenance therapy after HCT in Ph+ALL patients with T315I mutation. BCR-ABL kinase domain mutations were assessed using direct sequencing. Twenty-six Ph+ALL patients with T315I mutation who received allogeneic HCT were enrolled. After HCT, ponatinib was administered as a prophylactic regimen (n = 12) or a preemptive therapy (n = 7). Seven patients did not receive maintenance therapy. Adverse events (AEs) occurred in 69.4 % of patients with ponatinib maintenance, but most presented with mild toxicities. Serious non-hematological AEs were not observed. The 5-year disease-free survival (DFS), overall survival (OS), and cumulative incidence of relapse in patients receiving prophylactic ponatinib were 81.5 %, 91.7 %, and 18.5 %, respectively, whereas they were 39.8 %, 46.0 %, and 48.4 % in the total cohort, respectively. The measurable BCR-ABL transcripts in the first three months after HCT was associated with poor DFS and OS, even with ponatinib therapy. We concluded that maintenance therapy with ponatinib is safe after HCT. Patients with T315I mutation who received prophylactic regimen showed promising results with an acceptable relapse rate and encouraging survival. However, patients with measurable BCR-ABL transcripts early post-transplant had poor outcomes.

Abstract
Poor graft function (PGF) is a life-threatening complication that occurs after transplantation and has a poor prognosis. With the rapid development of haploidentical hematopoietic stem cell transplantation, the pathogenesis of PGF has become an important issue. Studies of the pathogenesis of PGF have resulted in some success in CD34+-selected stem cell boosting. Mesenchymal stem cells, N-acetyl-l-cysteine, and eltrombopag have also been investigated as therapeutic strategies for PGF. However, predicting and preventing PGF remains challenging. Here, we propose that the seed, soil, and insect theories of aplastic anemia also apply to PGF; CD34+ cells are compared to seeds; the bone marrow microenvironment to soil; and virus infection, iron overload, and donor-specific anti-human leukocyte antigen antibodies to insects. From this perspective, we summarize the available information on the common risk factors of PGF, focusing on its potential mechanism. In addition, the safety and efficacy of new strategies for treating PGF are discussed to provide a foundation for preventing and treating this complex clinical problem.

A Comparison of the Clinical Outcomes of Haploidentical Transplantation and Other Graft Sources in Acute Lymphoblastic Leukemia: A Systematic Review and Meta-Analysis. CLINICAL LYMPHOMA, MYELOMA & LEUKEMIA 2022; 22:174-191. [PMID: 34802994 DOI: 10.1016/j.clml.2021.09.024] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/28/2021] [Accepted: 09/17/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Most likely due to the availability of potential stem cell sources, there appears to be a growing usage of haploidentical (haplo) donors for cases of acute lymphoblastic leukemia involving high-risk features or relapse. PATIENTS AND METHODS This study compared the outcomes of stem cell transplantations (SCTs) using haplo and other stem cell sources, namely, matched sibling donors (MSDs), matched unrelated donors (MUDs), and cord blood transplantations (CBTs). Literature searches were conducted of the MEDLINE and Embase databases from inception to December 2020. RESULTS Twenty-eight studies were examined (17 retrospective and 11 prospective). There were no significant differences in the overall survival of haplo and those of the other stem-cell sources. For haplo versus matched donor (MSD or MUD), the pooled odds ratio (OR) was 0.94 (95% CI, 0.79-1.12; I2, 22%); while for haplo versus CBT, the OR was 1.24 (95% CI, 0.78-1.96; I2, 28%). The cumulative relapse incidence was significantly higher for MSD than haplo (OR, 0.69; 95% CI, 0.48-0.99; I2, 48%). Both grade II-IV acute and long-term graft-versus-host disease (GVHD) were significantly higher for haplo than MSD (OR, 1.78; 95% CI, 1.15-2.74; I2, 28%; and OR, 1.33; 95% CI, 1.00-1.77; I2, 14%, respectively). The other clinical outcomes did not demonstrate any statistical differences. CONCLUSION The outcomes of patients treated with haplo-SCT appear comparable with those of the SCTs using other sources. The higher probability of developing GVHD supports the need for a novel method to harness T-cell alloreactivity.

Abstract
ABSTRACT Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is currently the standard of care for adult acute lymphoblastic leukemia (ALL) patients. In recent years, with the continuous development of immunotherapy, such as chimeric antigen receptor T cells, blinatumomab, and inotuzumab ozogamicin, a series of vital clinical studies have confirmed its high response rate and favorable outcomes for ALL. Although the emergence of immunotherapy has expanded relapsed or refractory (r/r) ALL patients' opportunities to receive allo-HSCT, allo-HSCT is associated with potential challenges. In this review, the role of allo-HSCT in the treatment of adult ALL in the era of immunotherapy will be discussed.

Abstract
The number of HLA-haploidentical allogeneic hematopoietic stem-cell transplantation (Haplo-HSCT) is increasing. Comparative studies about Haplo-HSCT versus allo-HSCT with HLA-matched sibling donors (MSD-HSCT) have been tried in leukemias and B-cell lymphomas. Few studies were reported in Peripheral T-cell lymphomas (PTCLs). We performed a multicenter retrospective study about 52 patients with PTCLs undergoing Haplo-HSCT (n = 20) or MSD-HSCT (n = 32). All Haplo-HSCT recipients received antithymocyte globulin (ATG) based graft versus host disease (GVHD) prophylaxis. The median follow-up for all survivors was 38 months. The 100-day cumulative incidence of grade II to IV acute GVHD was similar (19% in the MSD-HSCT group versus 28% in the Haplo-HSCT group, P = 0.52). The 2-year cumulative incidence of chronic GVHD (limited and extensive) after Haplo-HSCT (30%) was also similar with that in the MSD-HSCT group (50%, P = 0.15). The 3-year relapse rates (33% vs 27%, P = 0.84) and non-relapse mortality (21% vs 22%, P = 0.78) did not differ between these two groups. There were also no differences in 3-year overall survival (OS) (48% vs 50%, P = 0.78) and progression-free survival (47% vs 51%, P = 0.95) between these two groups. On multivariate analysis, prognostic index for T-cell lymphoma (PIT) score (higher than 1: hazard ratio [HR], 4.0; P = 0.003) and disease status (stable or progression disease before HSCT: HR, 2.8; P = 0.03) were independent variables associated with worse OS. We concluded that ATG-based haplo-HSCT platform could work as an alternative to MSD-HSCT for patients with PTCLs.

Allogeneic Hematopoietic Stem Cell Transplantation Improved Survival for Adult Core Binding Factor Acute Myelogenous Leukemia Patients with Intermediate- and Adverse-Risk Genetics in the 2017 European LeukemiaNet. Transplant Cell Ther 2020; 27:173.e1-173.e9.

Abstract
The use of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for consolidation therapy in patients with core binding factor (CBF) acute myelogenous leukemia (AML) with intermediate- and adverse-risk genetics remains controversial. We retrospectively analyzed the clinical outcomes of 286 CBF-AML patients with intermediate- and adverse-risk genetics in first complete remission following consolidation with chemotherapy (n = 122), auto-HSCT (n = 27), or allo-HSCT (n = 137) between January 2009 and December 2018 at our center. Patients with allo-HSCT showed superior 5-year overall survival (OS; 74% versus 38% or 49%; P < .001) and progression-free survival (PFS; 74% versus 26% or 49%; P < .001) and lower cumulative incidence of relapse (CIR; 9% versus 69% or 31%; P < .001) compared with chemotherapy alone or auto-HSCT. In the allo-HSCT group, minimal residual disease (MRD) at the second and third months after allo-HSCT could predict relapse in t(8;21) patients (2 months: PCIR = .002; 3 months: PCIR < .001) but not in inv(16) patients. Moreover, positive MRD after 2 courses of consolidation chemotherapy before allo-HSCT was an independent risk factor for survival in CBF-AML patients with intermediate- and adverse-risk genetics, whereas haploidentical donor (haplo-) HSCT could overcome the adverse prognosis (5-year OS, 87%; 5-year PFS, 81%; 5-year CIR, 7%). Allo-HSCT could be the optimal first-line consolidation therapy for patients with intermediate- and adverse-risk genetics, and haplo-HSCT could improve survival for patients with positive MRD after 2 courses of consolidation chemotherapy.

Abstract
Relapse is a major cause of treatment failure in Philadelphia-chromosome-positive acute lymphoblastic leukemia (Ph+ALL) undergoing allogeneic hematopoietic cell transplantation (allo-HCT). This study aimed to evaluate the effect of a new pre-emptive tyrosine kinase inhibitors (TKIs) strategy on relapse in Ph+ALL patients with complete remission undergoing allo-HCT. Pre-emptive TKIs initiation was based on BCR/ABL molecular monitoring. TKIs choice was based on BCR/ABL mutations. Donor lymphocyte infusion was recommended in those with poor response to TKIs. Prophylactic TKIs from historical data were as control. The primary endpoint was relapse. One hundred and sixty-seven Ph+ALL patients were enrolled in this study, including 103 in the pre-emptive group and 64 in the prophylactic group. The 3-year cumulative incidence of relapse was 11% and 31% in the pre-emptive and prophylactic groups (P = 0.001), respectively. The 3-year overall survival (OS) was 87% and 66% (P = 0.001), and leukemia-free survival (LFS) was 83% and 61% (P = 0.000), respectively, in the pre-emptive and prophylactic groups. Multivariate analysis showed that the pre-emptive strategy was the protective factor for relapse, OS, and LFS (P = 0.005, P = 0.005, and P = 0.003, respectively). Our data suggest that this new pre-emptive TKIs strategy based on BCR/ABL molecular monitoring might reduce relapse and improve survival for Ph+ALL patients undergoing allo-HCT.

Abstract
Background: This study compared the effects of pre-transplantation measurable residual disease (pre-MRD) on outcomes in Philadelphia chromosome (Ph)-positive ALL patients who underwent human leukocyte antigen-matched sibling donor transplantation (MSDT) or who received unmanipulated haploidentical SCT (haplo-SCT). Methods: A retrospective study (n = 202) was performed. MRD was detected by RT-PCR and multiparameter flow cytometry. Results: In the total patient group, patients with positive pre-MRD had a higher 4-year cumulative incidence of relapse (CIR) than that in patients with negative pre-MRD (26.1% vs. 12.1%, P = 0.009); however, the cumulative incidence of non-relapse mortality (NRM) (7.4% vs. 15.9%, P = 0.148), probability of leukemia-free survival (LFS) (66.3% vs. 71.4%, P = 0.480), and overall survival (OS) (68.8% vs. 76.5%, P = 0.322) were comparable. In the MSDT group, patients with positive pre-MRD had increased 4-year CIR (56.4% vs. 13.8%, P < 0.001) and decreased 4-year LFS (35.9% vs. 71.0%, P = 0.024) and OS (35.9% vs. 77.6%, P = 0.011) compared with those with negative pre-MRD. In haplo-SCT settings, the 4-year CIR (14.8% vs. 10.7%, P = 0.297), NRM (7.3% vs. 16.3%, P = 0.187) and the 4-year probability of OS (77.7% vs. 72.3%, P = 0.804) and LFS (80.5% vs. 75.7%, P = 0.660) were comparable between pre-MRD positive and negative groups. In subgroup patients with positive pre-MRD, haplo-SCT had a lower 4-year CIR (14.8% vs. 56.4%, P = 0.021) and a higher 4-year LFS (77.7% vs. 35.9%, P = 0.036) and OS (80.5% vs. 35.9%, P = 0.027) than those of MSDT. Multivariate analysis showed that haplo-SCT was associated with lower CIR (HR, 0.288; P = 0.031), superior LFS (HR, 0.283; P = 0.019) and OS (HR, 0.252; P = 0.013) in cases with a positive pre-MRD subgroup. Conclusions: Our results indicate that the effects of positive pre-MRD on the outcomes of patients with Ph-positive ALL are different according to transplant modality. For Ph-positive cases with positive pre-MRD, haplo-SCT might have strong graft-vs.-leukemia (GVL) effects.

Abstract
The role of hematopoietic cell transplantation (HCT) in adults with acute lymphoblastic leukemia (ALL) is reviewed and critically evaluated in this systematic evidence-based review. Specific criteria were used for searching the published literature and for grading the quality and strength of the evidence and the strength of the recommendations. A panel of ALL experts developed consensus on the treatment recommendations based on the evidence. Allogeneic HCT offers a survival benefit in selected patients with ALL, and this review summarizes the standard indications as well as the areas of controversy. There is now greater experience with pediatric-inspired chemotherapy regimens that has transformed upfront therapy for adult ALL, resulting in higher remission rates and overall survival. This in turn has increased the equipoise around decision making for ALL in first complete remission (CR1) when there is no measurable residual disease (MRD) at the end of induction and/or consolidation. Randomized studies are needed for adults with ALL to compare allogeneic HCT in CR1 with pediatric-inspired chemotherapy alone. Indications for transplantation in the evolving landscape of MRD assessments and novel targeted and immune therapeutics remain important areas of investigation.

Abstract
Relapsed and refractory acute myeloid leukemia (R/R AML) has complicated pathogenesis. Its treatment is complicated, and the prognosis is poor. So far, there is no consensus on what is the optimal treatment strategy. With the deepening of research, new chemotherapy regimens, new small molecule inhibitors, and immunotherapy have been increasingly applied to clinical trials, providing more possibilities for the treatment of R/R AML. The most effective treatment for patients who achieve complete remission after recurrence is still sequential conditioning therapy followed by allogeneic hematopoietic cell transplantation. Finding the best combination of treatments is still an important goal for the future.

Abstract
The outcome for adults with acute lymphoblastic leukemia (ALL) treated with chemotherapy or autologous hematopoietic stem cell transplantation (HSCT) is poor. Therefore, allogeneic HSCT (allo HSCT) for adults aged less than 50 years with ALL is performed with myeloablative conditioning (MAC) regimens. Among the several MAC regimens, a conditioning regimen of 120 mg/kg (60mg/kg for two days) cyclophosphamide (CY) and 12 gray fractionated (12 gray in six fractions for three days) total body irradiation (TBI) is commonly used, resulting in a long term survival rate of approximately 50% when transplanted at the first complete remission. The addition of 30 mg/kg (15 mg/kg for two days) etoposide (ETP) to the CY/TBI regimen revealed an excellent outcome (a long-term survival rate of approximately 80%) in adults with ALL, showing lower relapse and non-relapse mortality rates. It is preferable to perform allo HSCT with a medium-dose ETP/CY/TBI conditioning regimen at the first complete remission in high-risk ALL patients and at the second complete remission (in addition to the first complete remission) in standard-risk ALL patients. The ETP dose and administration schedule are important factors for reducing the relapse and non-relapse mortality rates, preserving a better outcome. The pharmacological study suggests that the prolonged administration of ETP at a reduced dose is a promising treatment.

Abstract
Newly diagnosed acute myeloid leukemia (AML) failed to achieve complete remission after two courses of intensive chemotherapy. This was considered as primary refractory AML (PRR-AML), and still has a dismal prognosis. Allogeneic hematopoietic stem cell transplantation could be the only cure for these patients. However, the role of haploidentical hematopoietic stem cell transplantation (HID-HCT) for PRR-AML is still undetermined. We retrospectively analyzed the outcomes of 45 adult patients with PRR-AML who underwent HID-HCT, and compared it with the result of 53 patients who received HLA-matched related or unrelated donor transplantation (MD-HCT) during the same treatment period. The 3-year overall survival (OS), leukemia-free survival (LFS), cumulative incidence of relapse (CIR), and non-relapse mortality (NRM) rates in the HID-HCT group were 19.0, 16.5, 70.0, and 35.2%, respectively, but showed no significant differences from the results of MD-HCT. Multivariate analysis showed that complex karyotype with del(7) and time > 6 months from diagnosis to transplantation were associated with lower OS and LFS, and chronic GVHD demonstrated better OS and LFS in the entire cohort. Complex karyotype with del(7) was related with higher CIR and chronic GVHD with lower CIR. In conclusion, HID-HCT could be an alternative treatment strategy to improve the long-term survival in PRR-AML adult patients who have no HLA-matched donors.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is widely used to treat malignant hematological neoplasms and non-malignant hematological disorders. Approximately, 5000 allo-HSCT procedures are performed in China annually. Substantial progress has been made in haploidentical HSCT (HID-HSCT), pre-transplantation risk stratification, and donor selection in allo-HSCT, especially after the establishment of the "Beijing Protocol" HID-HSCT system. Transplant indications for selected subgroups in low-risk leukemia or severe aplastic anemia (SAA) differ from those in the Western world. These unique systems developed by Chinese doctors may inspire the refining of global clinical practice. We reviewed the efficacy of allo-HSCT practice from available Chinese studies on behalf of the HSCT workgroup of the Chinese Society of Hematology, Chinese Medical Association and compared these studies to the consensus or guideline outside China. We summarized the consensus on routine practices of all-HSCT in China and focused on the recommendations of indications, conditioning regimen, and donor selection.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains an important curative option for children with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) who have a poor response to chemotherapy plus imatinib. For such children, if there are no matched related or unrelated donors, alternative donor transplantation may be a choice. The role of haploidentical donor (HID) HSCT in pediatric patients with Ph+ ALL has not been reported. The study population included pediatric patients with Ph+ ALL who underwent HID-HSCT. BCR-ABL transcript levels were analyzed using real-time quantitative reverse transcription polymerase chain reaction. At a median follow-up of 34 months, the 5-year probabilities of event-free survival (EFS) and overall survival (OS) were 61.0% and 70.0%, respectively in HID HSCT. The 3-year incidence of relapse and non-relapse mortality was 22.7% and 16.4%. Multivariate analysis showed that the post-HSCT BCR-ABL transcript level on +30day was a significant factor affecting relapse rate. HID HSCT for the treatment of pediatric patients with Ph+ ALL yielded promising long-term survival. Post-HSCT BCR-ABL transcript positivity was a significant factor for clinical relapse after allo-HSCT in the imatinib era.

A review of hematopoietic cell transplantation in China: data and trends during 2008-2016. Bone Marrow Transplant 2017; 52:1512-1518. [PMID: 28436973 DOI: 10.1038/bmt.2017.59] [Citation(s) in RCA: 53] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2016] [Revised: 02/08/2017] [Accepted: 02/13/2017] [Indexed: 02/05/2023]
Abstract
Hematopoietic cell transplantation (HCT) activity in China was surveyed to assess its current status. A record number of HCTs (21 884: 16 631 allogeneic (76%) and 5253 autologous (24%)) were reported by 76 centers in China between 1 January 2008 and 30 June 2016. HCT trends included continued growth in transplant activity, a continued rapid increase in haploidentical donors (HID), and slower growth for unrelated donors, matched-related donors (MRD) and cord blood transplantation (CBT). The proportion of HID HCT among allogeneic HCTs increased from 29.6% (313/1062) in 2008 to 48.8% (1939/3975) in 2015, even 51.7% (1157/2237) in the first half of 2016. During this time frame, the proportion of MRD HCTs among allogeneic HCTs decreased from 48.1% (511/1062) to 33.0% (332/3975). The proportion of unrelated donor HCTs among allogeneic HCTs decreased from 20.4 (216/1062) to 13.6% (540/3975). The proportion of CBTs among allogeneic HCTs was increased from 2.1% (22/1062) to 4.2% (184/3975). HCTs have been increasing continuously for all indications except chronic myelogenous leukemia. Severe aplastic anemia is a common HCT indication among non-malignant diseases in China. The number of cases of allogeneic HCT for this disorder has increased annually, from 59 (5.6%) in 2008 to 569 (14.3%) in 2015, even 334 (14.9%) in the first half year in 2016. This survey clearly shows recent trends for HCTs in China.

Efficacy and prognostic factors of imatinib plus CALLG2008 protocol in adult patients with newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia. Front Med 2017; 11:229-238. [PMID: 28349299 DOI: 10.1007/s11684-017-0506-y] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2016] [Accepted: 11/24/2016] [Indexed: 12/11/2022]
Abstract
A CALLG2008 protocol was developed by the Chinese Acute Lymphoblastic Leukemia Cooperative Group for adult acute lymphoblastic leukemia (ALL). We retrospectively analyzed 153 newly diagnosed adult patients with Philadelphia chromosome (Ph)-positive ALL enrolled into imatinib (400 mg/d) plus CALLG2008 regimen between 2009 and 2015. The median age was 40 years (range, 18-68 years), with 81 (52.3%) males. The overall hematologic complete remission (CR) rate was 96.7% after induction. With a median follow-up of 24.2 months, the estimated 3-year overall survival (OS) and event-free survival (EFS) rates were 49.5%(95%confidence interval (CI): 38.5%-59.5%) and 49.2% (95% CI: 38.3%-59.2%), respectively. Fifty-eight (36 with haploidentical donor) patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) in first CR. Among the patients in CR1 after induction, both the 3-year OS and EFS were significantly better in the allo-HSCT group than in the without allo-HSCT group (73.2%, 95% CI: 58.3%-83.5% vs. 22.2%, 95% CI: 8.7%-39.6% and 66.5%, 95% CI: 50.7%-78.2% vs. 16.1%, 95% CI: 5.1%-32.7%, respectively). Multivariate analysis showed that allo-HSCT and achievement of major molecular response were associated with favorable OS or EFS independently. Interestingly, in the allo-HSCT cohort, the donor type (haploidentical versus matched donors) had no significant impact on EFS or OS. All these results suggested that imatinib plus CALLG2008 was an effective protocol for Ph-positive ALL. Haploidentical donors can also be a reasonable alternative expedient donor pool.

Abstract
Allogeneic blood or bone-marrow transplantation (alloBMT) is a potentially curative treatment for a variety of haematological malignancies and nonmalignant diseases. Historically, human leukocyte antigen (HLA)-matched siblings have been the preferred source of donor cells owing to superior outcomes compared with alloBMT using other donors. Although only approximately one-third of patients have an HLA-matched sibling, nearly all patients have HLA-haploidentical related donors. Early studies using HLA-haploidentical alloBMT resulted in unacceptably high rates of graft rejection and graft-versus-host disease (GVHD), leading to high nonrelapse mortality and consequently poor survival. Several novel approaches to HLA-haploidentical alloBMT have yielded encouraging results with high rates of successful engraftment, effective GVHD control and favourable outcomes. In fact, outcomes of several retrospective comparative studies seem similar to those seen using other allograft sources, including those of HLA-matched-sibling alloBMT. In this Review, we provide an overview of the three most-developed approaches to HLA-haploidentical alloBMT: T-cell depletion with 'megadose' CD34(+) cells; granulocyte colony-stimulating factor-primed allografts combined with intensive pharmacological immunosuppression, including antithymocyte globulin; and high-dose, post-transplantation cyclophosphamide. We review the preclinical and biological data supporting each approach, results from major clinical studies, and completed or ongoing clinical studies comparing these approaches with other alloBMT platforms.

Abstract
The outcomes of adult acute lymphoblastic leukemia (ALL) patients with chemotherapy or autologous hematopoietic stem cell transplantation (HSCT) are unsatisfactory. Therefore, allogeneic (allo) HSCT has been applied to those patients in first complete remission (CR1), and has shown a long-term survival rate of approximately 50 %. In terms of myeloablative conditioning (MAC) regimen, higher dose of cyclophosphamide (CY) and total body irradiation (TBI) (the standard CY + TBI) has been generally applied to allo HSCT. Other MAC regimens such as busulfan-based or etoposide-based regimens have also been used. Among those, medium-dose etoposide (ETP) in addition to the standard CY + TBI conditioning regimen appears to be promising for allo HSCT in adult ALL when transplanted in ALL patients aged under 50 years in CR1 and also in CR2, showing an excellent outcome without increasing relapse or transplant-related mortality (TRM) rates. By contrast, reduced-intensity conditioning (RIC) regimens have also been applied to adult ALL patients and favorable outcomes have been obtained; however, relapse and TRM rates remain high. Therefore, an allo HSCT conditioning regimen which deserves further study for adult ALL patients aged under 50 years in CR1 and CR2 appears to be medium-dose ETP + CY + TBI and RIC is suitable for patients aged over 50 years or for younger patients with comorbid conditions. On the contrary, new therapeutic strategies for adult ALL patients are increasingly utilized with better outcomes; namely, various tyrosine kinase inhibitors for Philadelphia chromosome (Ph)-positive ALL, human leukocyte antigen-haploidentical HSCT, and pediatric-inspired regimens for Ph-negative ALL. Therefore, the optimal treatment modality should be selected considering patient’s age, Ph-positivity, donor availability, risk classification, efficacy, and safety.

Abstract
Human leukocyte antigen (HLA)-haploidentical hematopoietic stem cell transplantation (HLA-haplo HSCT) without T-cell depletion has tremendously progressed over the past 20 years and has become a feasible treatment option for leukemia patients without an HLA-identical sibling donor. Advances in conditioning regimens, graft manipulation, and pharmacological graft-versus-host disease (GVHD) prophylaxis have reduced the risk of fatal graft failure and severe GVHD, two of the most serious complications of traversing the HLA barrier. According to clinical observations, killer immunoglobulin-like receptor (KIR) mismatch and donor-specific anti-HLA (DSA) antibodies-negative status play potential roles in reducing the risk of GVHD and graft failure following HLA-haploidentical SCT. New strategies to improve transplant outcomes include donor lymphocyte, NK cell and selected T-cell subset infusion, mesenchymal stem cell (MSC) co-transplantation and interleukin-2 (IL-2) application. Future challenges remain in improving post-transplant immune reconstitution and finding the best approach to reduce the incidence and severity of GVHD while simultaneously preserving the graft-versus leukemia effect to prevent the recurrence of underlying malignancy.
