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.

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.

Cd20 Expression

Abstract CD20 expression is associated with early recurrence and inferior survival in precursor-B acute lymphoblastic leukemia patients treated with chemotherapy. Whether CD20 influences outcomes after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is unknown. We analyzed CD20 expression on blasts at diagnosis in 157 patients who underwent allo-HSCT in the first complete remission (57%) or the second complete remission (43%). Of 125 evaluable patients, 71 were ≥ 20 years of age. CD20 expression was observed in 58 patients (46%; 52% of children, 39% of adults). There was no association between age, Ph+ status, white blood cell count at diagnosis, and CD20 positivity. After allo-HSCT, disease-free survival at 5 years was 48% for all patients, 55% (95% confidence interval 40%-67%) for CD20+ patients, and 43% (95% confidence interval 30%-54%) for CD20− patients (P = .15). Relapse did not differ between the groups. These results can serve as a reference to evaluate incorporation of anti-CD20 therapeutics to HSCT for the CD20+ acute lymphoblastic leukemia subset. Clinical trial numbers for www.clinicaltrials.gov are NCT00365287, NCT00305682, and NCT00303719.

Background: B-acute lymphoblastic leukemia (B-ALL) with t(v;11q23)/MLL-rearrangement (MLL-r) in children (1 year or older) is rare, and its outcome and optimal treatment options remain controversial. This study aimed to analyze the clinical characteristics and outcomes of these patients, and to explore the role of allogeneic hematopoietic stem cell transplantation (allo-HSCT), especially haploidentical HSCT (haplo-HSCT) in the treatment of these patients. Methods: At the time of the last follow-up (July 1, 2019), we retrospectively analyzed clinical data of 42 non-infant children with t(v;11q23)/MLL-r B-ALL. Comparison of outcomes was made between patients received allo-HSCT in the first complete remission (CR1) and chemotherapy only. Results: The median follow-up was 41 (1-106) months. The median age at diagnosis was 4.5(1-14) years and the median leukocyte count was 56.0 (2.2-735.2)×109/L. One was excluded for death during induction. For the remaining 41 patients, the complete remission rate after induction therapy was 40/41 (97.6%), the estimated 4-year probabilities of overall survival (OS), event-free survival (EFS) and cumulative incidence of relapse (CIR) were 59.7%, 51.6% and 43.4%, respectively. 19 patients received allo-HSCT in CR1 (HSCT in CR1 cohort), notably, 18/19 cases in this cohort received haplo-HSCT, and the remaining 22 patients continued the consolidation therapy (Non-HSCT in CR1 cohort). The estimated 4-year probabilities of OS, EFS and CIR in the HSCT in CR1 cohort were 86.6%, 89.2% and 5.3%, respectively. Meanwhile, the estimated 4-year probabilities of OS, EFS and CIR in the Non-HSCT in CR1 cohort were 37.5%, 19.9% and 75.6%, respectively. They were considered to be statistically significant. Of the 17 patients who relapsed during consolidation chemotherapy, 9 patients who underwent chemotherapy only (Non-HSCT after relapse cohort) all died within 44 months. For the remaining 8 patients who chose allo-HSCT (HSCT in CR2 cohort) when they achieved the second complete remission (CR2), the estimated 4-year probability of OS was 47.6% (P=0.002). Multivariate analysis showed that HSCT in CR1 was the only independent protective factor for OS, EFS and CIR, and age at diagnosis (≥10 years) was an independent risk factor of OS. Conclusions: Allo-HSCT (especially haplo-HSCT) in CR1 may reduce the risk of relapse and improve prognosis in non-infant children with MLL-r B-ALL. In addition, allo-HSCT also seemed to be an effective approach to improve the prognosis of relapsed patients. Thus, haplo-HSCT could be an alternative approach for non-infant children with MLL-r B-ALL. Disclosures No relevant conflicts of interest to declare.
