Abstract
Allogeneic stem cell transplantation (SCT) is currently the only curative treatment option for chronic myeloid leukemia (CML) patients with BCR-ABL T315I mutations. We report the outcome of SCT in 22 patients with T315I(+) CML, most (n = 16) from haploidentical family donors (HID-SCT). At the time the mutation was detected, 8 patients were in the chronic phase (CP), 7 in the accelerated phase (AP), and 7 in the blast phase (BP). At the time of SCT 7 were in the CP, 8 in the AP or returning to the CP post-AP (AP/AP-CPn), and 7 in the BP or returning to CP post-BP (BP/BP-CPn). The cumulative incidence of grades III to IV acute graft-versus-host disease was 9.1%. Chronic graft-versus-host disease was observed in 60.0% of patients, including 25.0% who suffered from severe disease. Four patients died of transplant-related complications at a median interval from SCT of 16.3 months. The estimated 2-year leukemia-free survival rate was 80.0%, 72.9%, and 0% in CP, AP/AP-CPn and BP/BP-CPn groups at the time of SCT, respectively. After a median follow-up of 17.3 months from SCT, 14 patients are alive, including 13 in complete molecular response and 1 with an extramedullary relapse. In conclusion, HID-SCT is a potentially curative treatment for T315I + CML patients. For patients in CP/AP, immediate SCT might result in promising survival. The outcome of patients in BP with T315I(+) mutation remains very poor.

Abstract
Background Since the introduction of tyrosine kinase inhibitors (TKIs) into combination chemotherapy regimens, the majority of newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) patients have achieved complete remission (CR). However, without allogeneic hematopoietic stem cell transplantation (HSCT), long-term outcomes in adults remain unsatisfactory. Indeed, haploidentical HSCT has become a common treatment for adult patients who lack an HLA-matched donor, though limited data are available on the efficacy of haploidentical HSCT in Ph+ ALL patients. Methods We analyzed the clinical outcomes of 82 Ph+ ALL patients who underwent haploidentical HSCT (n = 47) or HLA-matched HSCT (n = 35). Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was performed to assess BCR-ABL expression. All of the patients were treated with an imatinib-based regimen before undergoing HSCT. Imatinib treatment was resumed in the patients’ posttransplantation following detection of BCR-ABL transcripts. Results All of the patients achieved neutrophil and platelet engraftment, with the exception of five patients who died prior to engraftment. Haploidentical HSCT was associated with higher incidences of acute graft-versus-host disease (GVHD) (51.1 vs. 25.7 %, p < 0.05) and chronic GVHD (48.9 vs. 25.7 %, p < 0.05) compared with HLA-matched HSCT, but there was no difference in the incidence of either grades III–IV acute GVHD or extensive chronic GVHD. The incidence of cytomegalovirus (CMV) infection was significantly higher in the patients treated with haploidentical HSCT than in those treated with HLA-matched HSCT (38.3 vs. 14.3 %, p < 0.05). Haploidentical HSCT was associated with a significantly lower relapse rate compared with HLA-matched HSCT (44.8 vs. 19.1 %, p < 0.05). There were no differences in non-relapse mortality (NRM), leukemia-free survival (LFS), or overall survival (OS) between the patients who received HLA-matched HSCT and those who underwent haploidentical HSCT. Conclusions Our data indicate that the incidence of NRM after HSCT is similar between the patients who receive HLA-matched donor cells and those who receive haploidentical donor cells and that haploidentical HSCT reduces the relapse rate. Haploidentical HSCT represents an encouraging treatment option for Ph+ ALL patients who lack a suitable HLA-matched donor.

Haploidentical hematopoietic stem cell transplantation in adults with Philadelphia-negative acute lymphoblastic leukemia: no difference in the high- and low-risk groups. Int J Cancer 2014; 136:1697-707. [PMID: 25138425 DOI: 10.1002/ijc.29146] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2014] [Revised: 08/06/2014] [Accepted: 08/08/2014] [Indexed: 01/10/2023]
Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) is the most effective post-consolidation therapy and curative option for adult patients with Philadelphia chromosome-negative (Ph-negative) acute lymphoblastic leukemia (ALL) in first complete remission (CR1). A human leukocyte antigen (HLA)-haploidentical related donor (haplo-RD) is one of the most important alternative sources for those without HLA-identical sibling donor (ISD). The present study aimed to evaluate the outcomes of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) in adult Ph-negative ALL CR1 patients (n = 183). We produced an unmanipulated haplo-HSCT protocol including granulocyte colony stimulating factor (G-CSF) for all donors, intensive immune suppression, anti-thymocyte globulin, and combination of G-CSF-primed bone marrow harvest and G-CSF-mobilized peripheral blood stem cells harvest as the source of stem cell grafts. The median age for high-risk versus low-risk groups were 29 versus 23 years. Three-year incidences of relapse mortality and nonrelapse mortality for high-risk versus low-risk groups were 7.1% versus 11.1% (p = 0.498) and 18.0% versus 16.2% (p = 0.717), respectively. Three-year probabilities of disease-free survival and overall survival for high-risk versus low-risk groups were 67.6% versus 68.2% (p = 0.896) and 74.9% versus 72.7% (p = 0.981), respectively. Multivariate analysis showed that limited cGVHD and a lower pre-HSCT comorbidity burden were associated with better outcomes. In summary, comparable outcomes were observed among high- and low-risk Ph-negative ALL CR1 patients after haplo-HSCT. Haplo-RD could be considered for adults with Ph-negative ALL in CR1 as an important alternative source of donors in cases when no ISD is available.

Abstract
While previous studies have shown comparable clinical results for related and unrelated bone marrow transplantation (BMT), the transplantation outcomes for related and unrelated peripheral blood stem cell transplantation (PBSCT) may not follow the same pattern due to a higher incidence of graft-versus-host disease (GVHD)-related morbidity and mortality in the case of long-term survival after unrelated PBSCT. Thus, given the higher possibility of an impaired quality of life due to severe GVHD in long-term survivors who receive unrelated PBSCT, the selection of the stem cell source needs to be decided very carefully. In addition, strategic approaches, such as the extended use of immunosuppressant as a GVHD prophylaxis, the use of antithymocyte globulins (ATGs), choosing a younger donor, and optimizing the CD34+ cell dose, need to be adopted to improve the transplantation outcomes by minimizing GVHD-related morbidity and mortality in an unrelated PBSCT setting. This review article provides a comparison of BMT and PBSCT, and related and unrelated PBSCT, plus introduces several adoptable strategies to improve the outcomes of unrelated PBSCT.

Abstract
ALL remains a difficult disease to treat. In the adult setting, most patients will ultimately die of their disease, whereas in the pediatric setting, relapsed and refractory disease remains a therapeutic challenge. Cellular therapy through allo-HSCT remains an option for these patients, and recent advances in alternative forms of allo-HSCT, including unrelated donor transplants, UCB transplants, and haploidentical transplants, have expanded the numbers of patients eligible for allo-HSCT but have not improved outcomes when compared with HLA-matched related allo-HSCTs. In light of this persistent failure, several novel adoptive cellular approaches are being investigated to treat patients with ALL. The use of enriched WT-1–specific donor T cells to treat patients with ALL is currently under investigation in phase I trials at several centers. Treatment of ALL with genetically modified T cells targeted to the CD19 antigen through the expression of a CD19-specific CAR also have entered phase I clinical trials at several centers. Similarly, a clinical trial treating patients with ALL with genetically modified NK cells targeted to the CD19 antigen has recently opened for accrual. Collectively, these ongoing and anticipated trials provide a promising role for adoptive cellular therapies in the treatment of ALL. What remains to be seen is whether this promise will either translate into improved outcomes for these patients or provide significant insights on which to design second-generation adoptive cell therapeutic clinical trials for ALL in the future.

Abstract
Clinical research published since the first evidence-based review on the role of hematopoietic stem cell transplantation (SCT) in the treatment of acute lymphoblastic leukemia (ALL) in adults is presented and critically evaluated in this update. Treatment recommendations changed or modified based on new evidence include: (1) myeloablative allogeneic SCT is an appropriate treatment for adult (<35 years) ALL in first complete remission for all disease risk groups; and (2) reduced-intensity conditioning may produce similar outcomes to myeloablative regimens. Treatment recommendations unchanged or strengthened by new evidence include: (1) allogeneic SCT is recommended over chemotherapy for ALL in second complete remission or greater; (2) allogeneic is superior to autologous SCT; and (3) there are similar survival outcomes after related and unrelated allogeneic SCT. New treatment recommendations based on new evidence include: (1) in the absence of a suitable allogeneic donor, autologous SCT may be an appropriate therapy, but results in a high relapse rate; (2) it is appropriate to consider cord blood transplantation for patients with no HLA well-matched donor; and (3) imatinib therapy before and/or after SCT (for Ph+ ALL) yields significantly superior survival outcomes. Areas of needed research in the treatment of adult ALL with SCT were identified and presented in the review.

Abstract
Approximately 10% of children with ALL present at diagnosis with VHR for relapse if treated with chemotherapy alone. They may benefit from allogeneic HSCT in CR1. We have reviewed the outcome of this population in our institution. Forty-three patients (median age: 8.9 yr) with VHR ALL in CR1 underwent HSCT from October 1994 to April 2006. VHR features included Philadelphia chromosome (n = 17), induction failure (n = 9), hypodiploidy (n = 6), MLL gene rearrangement (n = 5), and others (n = 6). All patients received TBI (1200 cGy) with either CY and/or etoposide. Stem cell source was unrelated (n = 24) and related (n = 19). Incidence of grade III-IV acute GVHD and chronic extensive GVHD were 25% and 16%, respectively. Twelve patients relapsed (eight received related HSCT). Eleven patients died due to transplant-related mortality (eight received unrelated HSCT). For a median follow up of 39 months (range 11-110), the event free survival and OS were 0.49 (95% CI: 0.31-0.67) and 0.53 (CI: 0.44-0.71), respectively. Outcomes of children with VHR ALL receiving HSCT in CR1 remain unsatisfactory. Relapse, mainly after related HSCT, and TRM, mainly after unrelated HSCT, continue to be major problems.

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

Abstract
Stem cell transplants save lives of many patients with blood diseases. Donation is painful, but rarely has lasting adverse effects. Patients can accept transplants only from donors with compatible immune systems. Those lacking a sibling match must seek donations from the general population. The probability that two unrelated persons are compatible is less than 1/10,000. Health authorities maintain a registry of several million genetically tested potential donors who agree to donate if asked. We find that the benefits of adding registrants of every race exceed costs. We also explore the peculiar structure of voluntary public good provision that faces potential donors.

Abstract
We studied the relative impact of donor source on outcomes following myeloablative hematopoietic stem cell transplantation (HSCT) for adult patients with acute lymphocytic leukemia (ALL). In this single center study, 138 patients aged 18-61 (median 31) years underwent myeloablative conditioning followed by allogeneic HSCT. Stem cell source was an HLA matched related donor (MRD) in 90, HLA matched unrelated donor (URD:M) in 15, HLA mismatched unrelated donor (URD:MM) in 14, and HLA 0-2 (A, B, DRB1) mismatched umbilical cord blood (UCB) in 19 patients. At the time of HSCT, 70 patients were in first clinical remission (CR1), 57 in CR2, and 11 in > or =CR3. Twenty-one patients had T-lineage disease; 43 patients (31%) had high-risk cytogenetics of either t(9;22) (n = 33), t(4;11) or t(1,19) abnormalities, with the remainder (69%) having normal cytogenetics. White blood cell count (WBC) > or =30 x 10(9)/L at diagnosis was documented in 33%. Demographics and disease characteristics were similar in all 4 groups except all UCB recipients were treated since 1996 and received growth factors. Overall survival (OS) at 3 years for the UCB group was 66% (95% confidence interval [CI] 44%-89%) compared to 27% (95% CI 17%-36%) in the MRD group, and only 13% (95% CI 0%-31%) and 14% (95% CI 0%-33%) in the URD:M and URD:MM groups, respectively. Similarly leukemia free survival (LFS) at 3 years was better in the UCB group at 61% (95% CI 38%-84%) than 27% (95% CI 18%-36%) in the MRD and only 13% (95% CI 0%-31%) in the URD:M group and 14% (95%CI 0%-33%) in URD:MM group. Relapse rates at 3 years were 5% (95% CI 0%-15%) in the UCB group compared to 26% (95% CI 16%-35%) in the MRD, 20% (95% CI 1%-39%) in the URD:M groups, and 0% in the URD:MM groups. Transplant-related mortality (TRM) at 3 years was the lowest in the UCB group at 34% and higher in the other donor groups: MRD 47%, URD:M 67%, and URD:MM 86%. In multiple regression analysis, 5 independent risk factors were significantly associated with poorer OS and LFS: use of URD:MM (relative risk [RR] 2.5, 95% CI, 1.2-5.1, P = .01), > or =CR3 at HSCT (RR 3.5, 95% CI, 1.2-9.6, P = .02), WBC > or =30 x 10(9)/l (RR 1.9, 95% CI, 1.2-3.0, P = .01) at diagnosis, recipient and donor (R/D) cytomegalovirus (CMV) seropositive (RR 3.8, 95% CI, 2.0-7.4, P < .01), and > or =2 induction regimens to achieve initial CR (RR 3.5, 95% CI, 1.2-9.6, P = .02). Graft-versus-host disease (GVHD) was associated with improved LFS (RR 0.4, 95% CI, 0.2-0.6, P < .01). When compared with URD:M, OS with UCB was better (RR 0.3, 95% CI, 0.1-0.7, P = .01), supporting the use of UCB as an alternative stem cell source for adults with ALL.

Abstract
Allogeneic transplantation is an effective treatment for adult patients with high-risk ALL, including patients in first or second remission. Although only a few studies have evaluated the optimal transplant regimens, the data would suggest that a TBI-based regimen results in better disease control. Although not as potent as it is in other hematologic malignancies, the GVL effect is an important component of achieving cure of ALL. Because of the toxicity of the fully ablative regimen, reduced-intensity transplants are being explored in older patients with ALL when the prognosis is especially poor with standard chemotherapy.
