Abstract Autologous hematopoietic stem cell transplantation (HSCT) is a recognised option of post-consolidation therapy for adults with high-risk acute lymphoblastic leukemia (ALL) not having a donor. G-CSF-stimulated peripheral blood SCT results in faster recovery compared to cryopreserved bone marrow transplantation (BMT) and is currentlly used by the majority of centres. In the current study we analyze the feasibility of a new technique of autologous BMT, which does not require cryopreservation. 115 adult patients (median age 24.5 (16–53) years) with high-risk ALL in first complete remission (CR) were treated with autologous BMT between 1991–2004 in a single center using uniform standard operating procedures. Immune phenotype was as follows: proB 17%, preB 9%, common 44%, mature B 1%, preT 9%, mature T 19%. Initial WBC was >30 G/l in 30% of patients. 8% of patients were bcr/abl(+), 38% required >1 course of induction to achieve CR. Bone marrow was collected in general anaesthesia and further stored for 72 hours in 4degC without any processing and reinfused 24 hours after completion of myeloablative therapy. Conditioning regimen (CAV) consisted of cytarabine 2x1000 mg/m2 d. −3, −2, −1, etoposide 800 mg/m2 d. −3, −2, cyclophosphamide 60 mg/kg d. −3, −2. Median NC dose was 2.0 (0.9–10.8)x10e8, CD34+cell dose − 1.6 (0.4–15)x10e6/kg. Median recovery of ANC>0.5 G/l equaled 16(11–45) days, PLT>50 G/l – 16(10–53) days (11% patients received cytokines to stimulate NC recovery). Median duration of hospital stay since the date of BMT was 19(13–51) days. The OS rate at 10 years (median follow-up 6.5 years) equaled 57% (+/−5%), LFS rate − 47% (+/−5%). Three patients died within 100 days after ABMT of septic infections (non-relapse mortality rate − 2.6%). None of the analysed factors (age, WBC at diagnosis, immonophenotype, time to achieve CR) was found to influence the long-term outcome. We conclude that autologous transplantation of non-cryopreserved bone marrow after CAV conditioning is feasible for adults with high-risk ALL. The method is characterized by fast recovery, short hospital stay and low non-relapse mortality, and may constitute good alternative to autologous PBSCT.

Purpose The role of unrelated allogeneic stem-cell transplantation in acute lymphoblastic leukemia (ALL) patients is still not clear, and only limited data are available from the literature. We analyzed factors affecting clinical outcome of ALL patients receiving a related or unrelated stem-cell graft from matched donors. Patients and Methods The total study population was 264 adult patients receiving a myeloablative allogeneic stem-cell transplant for ALL at nine bone marrow transplantation centers between 1990 and 2002. Of these, 221 patients receiving a matched related or unrelated graft were analyzed. One hundred forty-eight patients received transplantation in complete remission; 62 patients were in relapse; and 11 patients were refractory to chemotherapy before transplant. Fifty percent of patients received bone marrow, and 50% received peripheral blood stem cell from a human leukocyte antigen–identical related (n = 103), or matched unrelated (n = 118) donor. Results Disease-free survival (DFS) at 5 years was 28%, with 76 patients (34%) still alive (2.2 to 103 months post-transplantation), and 145 deceased (65 relapses, transplant-related mortality, 45%). We observed an advantage regarding DFS in favor of patients receiving transplantation during their first complete remission (CR) in comparison with patients receiving transplantation in or after second CR (P = .014) or who relapsed (P < .001). We observed a clear trend toward improved survival in favor of B-lineage ALL patients compared with T-lineage ALL patients (P = .052), and Philadelphia chromosome–positive patients had no poorer outcome than Philadelphia chromosome–negative patients. Total-body irradiation–based conditioning improved DFS in comparison with busulfan (P = .041). Conclusion Myeloablative matched related or matched unrelated allogeneic hematopoietic stem-cell transplantation in ALL patients should be performed in first CR.

Abstract Purpose The role of hematopoietic stem cell transplantation (HSCT) for children with high-risk (HR) T- cell acute lymphoblastic leukemia (T-ALL) in first complete remission (CR1) is still under critical discussion. This study explored the hierarchical criteria, prognostic factors of childhood T-ALL, and the role of HSCT, especially haplo-HSCT, for children with HR T-ALL in CR1. Methods Seventy-four pediatric T-ALL patients were included in this study and stratified into low-risk chemotherapy cohort (n=16), high-risk chemotherapy cohort (n=31) and high-risk transplant cohort (n=24). Results Patient prognosis in the high-risk chemotherapy cohort was significantly inferior to the low-risk chemotherapy cohort (5-year overall survival (OS): 51.2%±10% vs. 100%, P = 0.003; 5-year event-free survival (EFS): 48.4%±9.8% vs. 93.8%±6.1%, P = 0.01; 5-year cumulative incidence of relapse (CIR): 45.5%±0.8% vs. 6.3%±0.4%, P = 0.043). The 5-year OS, EFS, and CIR of the high-risk transplant cohort were 77.0%±8.3%, 77.0%±8.3%, and 11.9%±0.4%, respectively. When compared to the high-risk chemotherapy cohort, the P values were 0.084, 0.041, and 0.011, respectively. Minimal residual disease (MRD) re-emergence, initial white blood cell (WBC) count, and age≥10 years were independent risk factors for prognosis. ConclusionsHSCT, especially haplo-HSCT, might effectively improve the survival outcomes for HR childhood T-ALL in CR1.

In adults with standard-risk acute lymphoblastic leukemia, the greatest benefit is achieved from a matched sibling allogeneic transplantation in first complete remission, and an autologous transplantation is less effective than conventional consolidation/maintenance chemotherapy in all patients: final results of the International ALL Trial (MRC UKALL XII/ECOG E2993)

An international collaboration was set up to prospectively evaluate the role of allogeneic transplantation for adults with acute lymphoblastic leukemia (ALL) and compare autologous transplantation with standard chemotherapy. Patients received 2 phases of induction and, if in remission, were assigned to allogeneic transplantation if they had a compatible sibling donor. Other patients were randomized to chemotherapy for 2.5 years versus an autologous transplantation. A donor versus no-donor analysis showed that Philadelphia chromosome–negative patients with a donor had a 5-year improved overall survival (OS), 53% versus 45% (P = .01), and the relapse rate was significantly lower (P ≤ .001). The survival difference was significant in standard-risk patients, but not in high-risk patients with a high nonrelapse mortality rate in the high-risk donor group. Patients randomized to chemotherapy had a higher 5-year OS (46%) than those randomized to autologous transplantation (37%; P = .03). Matched related allogeneic transplantations for ALL in first complete remission provide the most potent antileukemic therapy and considerable survival benefit for standard-risk patients. However, the transplantation-related mortality for high-risk older patients was unacceptably high and abrogated the reduction in relapse risk. There is no evidence that a single autologous transplantation can replace consolidation/maintenance in any risk group. This study is registered at http://clinicaltrials.gov as NCT00002514.

Abstract Abstract 2303 Poster Board II-280 Introduction: In acute lymphoblastic leukemia (ALL) specific clinical and biological features confer high relapse risk and inferior overall survival (OS) after treatment with conventional chemotherapy alone. The differential prognostic impact of these high risk features after treatment with allogeneic hematopoietic stem cell transplantation (HCT) has not been well studied. Patients and Methods: 79 adult ALL patients in first complete remission (CR) received allogeneic HCT at our center between 1995 and 2008. All patients were high or very high risk according to German Multicenter Study Group for Adult ALL (GMALL) criteria. Median age was 36 years (range: 17-68). Patients received high-dose conditioning consisting of 12 Gy total body irradiation ± etoposide ± cyclophosphamide (n=69, 87%) or reduced intensity conditioning (RIC) consisting of fludarabine/busulfan/ATG (n=10, 13%) and HSCT from related (n=34, 43%) or unrelated (n=45, 57%) donors. Bone marrow (n=17, 22%) or peripheral blood stem cells (n=62, 78%) were given. Graft-versus-host-disease prophylaxis was CSA/MTX for high-dose conditioning or CSA/MMF for RIC. Results: Patients were classified as high risk or very high risk due to Philadelphia chromosome-positive disease (Ph+) (n=30, 38%), leukocytosis>30/nl at diagnosis in B-ALL (n=25, 23%), late response to induction therapy in B-ALL (>week 4) (n=13, 16%), early or mature T-ALL (n=13, 16%), pro-B-ALL/t(4;11) (n=8, 10%), persistence of minimal residual disease (MRD) (>week 16) (n=8, 10%) or complex aberrant karyotype (n=6, 8%). 57 patients (72%) presented with one high risk feature, whereas 20 patients (25%) and 2 patients (3%) presented with two or three features, respectively. Currently, after a median follow-up of 56 months (7-169) 49 patients (62%) remain alive. Projected OS of the whole cohort at 1, 2 and 5 years was 78%, 70% and 55% and leukemia-free survival was 77%, 66% and 55%. Cumulative incidence of non-relapse mortality (NRM) and relapse mortality (RM) at 5 years was 23% and 18%, respectively. In multivariate Cox regression analysis, a non-significant trend for inferior OS was seen for patients with early or mature T-ALL (hazard ratio (HR): 2.03 (95%CI: 0.92-4.52), p=0.082), whereas no differential effect on OS, NRM or RM was seen for any other high risk feature (Table 1). In additional analyses, inferior OS (HR 1.81 (95%CI: 1.02-3.29), p=0.043) and increased RM (HR 2.17 (95%CI 1.16-4.05), p=0.015) was observed for patients with more than one high risk feature. Conclusions: In summary, this single center study on allogeneic HCT in high risk ALL found a negative prognostic trend for early or mature T cell immunophenotype. No differential prognostic impact on OS, NRM and RM was seen for other high risk features as defined by GMALL criteria, however this conclusion is limited by the low patient number in some of the subgroups. Overall survival for the whole cohort was 55% at 5 years, with inferior OS and higher RM being observed in patients with more than one high risk feature.

Abstract Background: Relapse of Philadelphia-chromosome-positive acute lymphoblastic leukemia (Ph+ALL) may result from the persistence of leukemia stem cells sometimes termed leukemia-propagating cells (LPCs). We recently found that Ph+ALL LPCs are enriched in the CD34+CD38-CD58- fraction using anti-CD122-conditioned NOD/SCID xenograft assay by intra-bone marrow injection, which translating to adverse clinical outcomes (Kong Y, et al. Leukemia 2014. accepted). Despite the widespread use of abelson tyrosine kinase inhibitors (TKIs) in Ph+ALL, allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the best curative option. However, whether the prognostic significance of the identified LPCs phenotype to identify patients at high risk for relapse could retain in Ph+ALL after allo-HSCT, if any, is unknown. Aims: To investigate the prognostic significance of the candidate CD34+CD38-CD58- LPCs in Ph+ALL subjects underwent allo-HSCT. Methods: A total of 80 consecutive adults (18-60 years) with Ph+ALL underwent allo-HSCT were eligible for the study at Peking University Institute of Hematology from January 1, 2009 to December 31, 2013. Imatinib was routinely administered in subjects pre- and post-HSCT as previously reported. A multi-parameter flow cytometry analysis of CD58-FITC/CD10-PE/CD19-APC-Cy7/CD34-PerCP/CD45-Vioblue/ CD38-APC on gated leukemia blasts of bone marrow was performed at diagnosis. Furthermore, minimal residual disease (MRD) was monitored by BCR/ABL transcripts in bone marrow samples at diagnosis, directly before transplantation, as well as serially at 1, 2, 3, 6, 9, 12,24,36,60 months post-HSCT and at relapse using real-time quantitative polymerase chain reaction. Cumulative incidences of relapse (CIR) and non-relapse mortality were calculated using the Kalbfleisch and Prentice method. Leukemia-free survival (LFS) and overall survival (OS) were estimated using the Kaplan-Meier method and compared using the log-rank test. Factors at a level of P<0.1 were included as variables in the multivariate Cox regression model. The study was approved by the Ethics Committee of Peking University People’s Hospital. Results: On the basis of blasts phenotypes at diagnosis, subjects were stratified into CD34+CD38-CD58- group (N=15) and other phenotype group (N=65). The demographic and clinical characteristics showed no significant difference between the two phenotype groups. Median follow-up was 25.5 mo (range, 6-65 mo) for all subjects and 33 mo (range, 6-65 mo) for survivors. During the MRD monitoring, significantly higher levels of BCR/ABL transcripts were detected in subjects in CD34+CD38-CD58- group than persons in other phenotype group especially at 3 mo post-HSCT [0.12(0-152.4)% vs. 0(0-100)%, P=0.001]. Additionally, CD34+CD38-CD58- LPCs phenotype directly correlated with higher 3-year CIR (63.2% [58.2-68.1%] vs. 5.3% [5.1-5.5%]; P<0.0001), worse LFS (30.2% [8.1-56.6%] vs. 78.7% [64.5-87.7%]; P=0.001) and OS (37.7% [12.6-63.2%] vs. 82.3% [68.5-90.4%]; P=0.0004). Multivariate analyses indicated that CD34+CD38-CD58- LPCs phenotype at diagnosis and BCR-ABL reduction at 3 mo post-HSCT were independent risk factors for relapse, LFS and OS in adults with Ph+ALL underwent allo-HSCT. Summary/Conclusion: Our data suggest that a candidate CD34+CD38-CD58- LPCs phenotype at diagnosis allows rapid identification of high-risk patients for relapse even after allo-HSCT. Risk-stratification post-HSCT therapy incorporating analysis of CD34+CD38-CD58- LPCs phenotype at diagnosis promises to benefit the adults with Ph+ALL in the future.

Abstract Aims: Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) patients generally have a poor prognosis when treated with chemotherapy alone. In adults, allogeneic hematopoietic stem cell transplantation (HSCT) in first complete remission is still the standard strategy for Ph+ALL. However, in children, HSCT should be avoided as much as possible to eliminate late complications. There are some reports showing that the combination of tyrosine kinase inhibitors (TKIs) with chemotherapy may avoid HSCT in childhood Ph+ALL. Thus, we planned this clinical trial (JPLSG ALL-Ph13) with the aim of improving outcomes with as few HSCT by chemotherapy with TKIs based on Ig/TCR minimal residual disease (MRD). Methods: Patients aged 1 to 19 with Ph+ALL were enrolled in JPLSG ALL-Ph13 Study. The diagnosis of Ph+ALL was performed using reverse-transcription PCR for BCR-ABL1. Chemotherapy follows the BFM ALL high-risk regimen (IA, IB, HR3, HR2, HR1, III, IM, III, IM, III, and maintenance). Imatinib was started on day 15 of induction therapy and continued until the final day of maintenance therapy (Ima group). If Ig/TCR MRD was positive (≥10 -4) at the end of IB, imatinib was changed to dasatinib and chemotherapy was continued (Dasa group). If MRD was positive at the end of the HR blocks, HSCT was performed (HSCT group). Results: During the period 2013-17, 43 patients were registered in this study, and 2 patients were excluded by not meeting inclusion criteria. Thirty-three, 7, and 1 patient were stratified into Ima, Dasa, and HSCT groups, respectively. Induction rate was 52.6% at the end of IA and 89.2% at the end of IB. MRD-negative rate was 61.3% at the end of IB and 87% at the end of HR. Although 51.2% of patients eventually received HSCT, only 13.9% received HSCT at the first complete remission. In all patients, the 3-year event-free survival (EFS) rate was 65.1%, and the 3-year overall survival (OS) rate was 85.1%. Four patients died of serious infections during treatment (2 in IA, 2 in 1st III). Interpretation: In our previous study for children with Ph+ALL (the JPLSG Ph+ALL04 study), all patients underwent HSCT, with the 3-year EFS rate of 57% and the OS rate of 80%. In this ALL-Ph13 study, the EFS and OS are almost the same as those in the Ph+ALL04. These are also almost the same as those in the EsPhALL2010 study, which aimed at avoiding HSCT. However, as in the EsPhALL2010 study, the comparatively high incidence of fatal adverse events was a problem with this study. Conclusion: Chemotherapy with the use of TKIs based on MRD has the potential to avoid HSCT in treatment for children with Ph+ALL. Reducing the occurrence of fatal adverse events is a future challenge to overcome. Disclosures No relevant conflicts of interest to declare.
