    Abstract Outcomes in patients with acute lymphoblastic leukemia (ALL) who experience relapse after allogeneic hematopoietic cell transplantation (HCT) are unsatisfactory. This study aimed to evaluate the outcomes of patients with ALL who underwent second HCT (HCT2) for relapse after first HCT. It was a single-center retrospective study including adult patients with ALL who underwent HCT2 between 1991 and 2020. The cohort was stratified according to the transplant year, and included 39 patients with a median age of 29 years. A more recent transplant year was associated with achievement of complete remission (CR) and use of reduced-intensity conditioning (RIC), compared with an earlier transplant year. The overall survival (OS) rate and 2-year cumulative incidence of non-relapse mortality (recent vs. earlier) were 55% vs. 8% (P < 0.001) and 26% vs. 75% (P < 0.001), respectively. In multivariate analysis, non-CR (vs. CR; HR 3.6, 95% CI 1.2-11.3, P = 0.025) and myeloablative conditioning (vs. RIC; HR 3.5, 95% CI 1.3-9.4, P = 0.011) were negative prognostic factors for OS. Outcomes of the recent cohort from real-world data are promising, and achieving CR and using the RIC regimen at HCT2 may be an important therapeutic strategy.

    Abstract Objectives and methods: This single-center retrospective study was performed to evaluate the safety and efficacy of FMS-like tyrosine kinase 3 (FLT3) inhibitors before and after allogeneic hematopoietic cell transplantation (HCT) in relapsed/refractory patients with FLT3-mutation positive acute myeloid leukemia (AML).
    Results: Ten patients who met the eligibility criteria were included. Eight of them achieved hematological remission at HCT, within a median span of 79 days (range: 43-197). In post-HCT, patients started maintenance therapy (MT; median time-to-start 79 days, range: 43-197), and the median duration of MT was 390 days (range: 67-815). Grade 3 hematological adverse events (AEs) were found in two patients, and non-hematological AEs were found in five patients. Nine patients underwent either dose reduction, discontinuation of therapy, or a switch to another FLT3 inhibitor due to AEs. Disease relapse occurred in one patient during MT. At the time of the last follow-up, seven patients are alive and disease-free, while three have died due to infection or transplant complications.
    Conclusion: In relapsed/refractory FLT3 mutation-positive AML, the use of FLT3 inhibitors can lead to high response rates and provide a safe bridge from HCT to MT. If sufficient attention is paid to safety, this therapy is expected to prevent disease relapse even with reduced dosages.

    Abstract This single-center retrospective study was performed in consecutive patients with acute lymphoblastic leukemia who relapsed after allogeneic hematopoietic cell transplantation (HCT) and received salvage therapy using inotuzumab ozogamicin (InO). Ten patients (median age: 27 years) treated between June 2018 and July 2020 who met the eligibility criteria were included in this study. Nine patients received InO in one cycle and seven of these patients achieved complete hematological remission after salvage chemotherapy including InO. Negative minimal residual disease was confirmed in all four evaluable patients. Eight patients were successfully bridged to the subsequent HCT. After HCT, veno-occlusive disease (VOD) developed in three patients, and caused the death of one. No patient received maintenance therapy. At present, five patients are disease-free and alive, and the overall and progression-free survival rates at 1 year were 60% and 40%, respectively. High rates of disease remission and bridging to HCT with comprehensive treatments including InO may have contributed to favorable outcomes. However, further investigation is needed to reduce post-HCT complications including VOD.

    Abstract There are no clear criteria for selecting elderly patients with hematologic malignancies eligible for allogeneic hematopoietic stem cell transplantation (HSCT). This study aimed to evaluate inflammatory and nutritional status biomarkers as prognostic indicators of allogeneic HSCT in elderly patients. We compared the prognostic effects of 4 representative pretransplantation biomarkers: C-reactive protein-to-albumin ratio (CAR), Glasgow Prognostic Score (GPS), prognostic nutritional index (PNI), and albumin-to-globulin ratio (AGR). A total of 143 patients age ≥60 years who underwent their first allogeneic HSCT for a hematologic malignancy were enrolled between 2010 and 2020 in our single-center cohort. The median patient age was 65 years (range, 60 to 72 years). Pretransplantation high CAR, high GPS, and low PNI scores were associated with poor overall survival (OS), but the AGR was not associated with OS. Among the 4 biomarkers, CAR stratified OS most significantly (P < .001). Multivariate analyses identified only high CAR as an independent prognostic factor associated with OS (hazard ratio [HR], 1.98; P = .031) and showed that a Hematopoietic Cell Transplantation-Specific Comorbidity Index (HCT-CI) score ≥3 also was associated with OS (HR, 2.04; P = .012). High CAR was correlated with poor performance status, male sex, and high Disease Risk Index, but not with high HCT-CI score. When the patients were stratified into 3 groups according to a composite risk assessment using CAR and HCT-CI, the 3-year OS decreased significantly with increasing scores (82.8%, 50.3%, and 27.0%, respectively; P < .0001). In conclusion, CAR is the most useful prognostic indicator among the inflammatory and nutritional status biomarkers for allogeneic HSCT in elderly patients. Inflammatory and nutritional status in the elderly may be important prognostic factors for allogeneic HSCT independent of HCT-CI score.

    Abstract The prognosis for relapsed adult T-cell leukemia/lymphoma (ATL) after allogeneic hematopoietic stem cell transplantation is poor. Here, we report the case of a 67-year-old man who survived for 26 months after treatment with lenalidomide for post-transplant relapsed ATL. He underwent induction therapy with two cycles of modified VCAP-AMP-VECP and achieved complete remission. He received cord blood cell transplantation following a reduced-intensity conditioning regimen. Seven months after transplantation, swelling of the systemic lymph nodes appeared, and relapsed ATL was diagnosed based on a biopsy of the cervical lymph node. Treatment with 10 mg of lenalidomide induced partial remission. At 18 months after transplantation, skin tumors were successfully treated by increasing the dose of lenalidomide to 15 mg with the emergence of skin graft-versus-host disease. Although he died from ATL at 34 months after transplantation, systemic relapsed lesions were controlled by treatment with lenalidomide for 26 months. Our case suggests that lenalidomide is well tolerated and is an effective option for the treatment of post-transplant relapsed ATL.

    Abstract Background: Various biomarkers have been developed and evaluated to predict the prognosis and complications of allogeneic hematopoietic cell transplantation (HCT). Most previous studies conducted on different biomarkers evaluated single effects such as those associated with inflammation, immunology, iron metabolism, and nutrition, and only a few studies have comprehensively analyzed markers.
    Objective: The study aimed to survey comprehensive multiple markers prior to HCT and extract those that significantly predict the outcomes.
    Study design: A prospective multicenter observational study was performed. (UMIN000013506) Patients undergoing HCT for hematologic diseases were consecutively enrolled. Besides the usual clinical biomarkers, serum samples for extra-clinical biomarkers were collected and cryopreserved before starting the conditioning regimen. A total of 32 candidate biomarkers were selected, 23 from hematology, biochemistry, immunology, nutrition, and iron metabolism, and 9 from composite markers. Based on the area under the curve (AUC) values for survival, promising biomarkers was extracted. Internal validation for these markers was applied based on bootstrap methods. Setting the cut-off values for them, log-rank test was applied and outcomes including overall survival (OS), relapse, and non-relapse mortality (NRM) were evaluated using multivariate analyses. Furthermore, detailed analysis including transplant-related complications and external validation were conducted focusing on C-reactive protein (CRP) to platelet (Plt) ratio.
    Results: A total of 152 patients with hematologic malignancies were enrolled from April 2014 to March 2017. CRP, soluble interleukin-2 receptor (IL2R), CRP to albumin (Alb) ratio, CRP to Plt ratio, Plt to IL2R ratio, and IL2R to Alb ratio were identified as promising markers. Internal validation successfully confirmed their reliability of AUC and multivariate analysis demonstrated the statistical significance between the higher and the lower markers. Above all, a higher CRP to Plt ratio was significantly associated with a lower OS (hazard ratio [HR] 2.77; 95% confidence interval [CI] 1.30-5.91; P = 0.008) and higher non-relapse mortality rates (HR 2.79; 95%CI 1.14-6.80; P = 0.024) at 180 days. Furthermore, univariate analysis showed that a higher CRP to Plt ratio was significantly associated with a higher incidence of sinusoidal obstructive syndrome (P < 0.001) and bloodstream infection (P = 0.027). An external validation test confirmed the significance of the CRP to Plt ratio for these outcomes.
    Conclusion: The multicenter prospective observational study successfully identified significant biomarkers in patients with hematologic malignancies who received HCT. In particular, CRP to Plt ratio was identified as a novel and useful biomarker for predicting transplant outcomes. Further investigations are needed to validate the novel markers, analysis of the pathophysiology, and application to treatment settings other than HCT.

    Abstract The optimal bridge strategy at the decision for allogeneic hematopoietic stem cell transplantation (HSCT) in patients with myelodysplastic syndrome (MDS) is unclear. We performed a prospective observational study in which 110 patients with MDS who were decided to undergo HSCT were enrolled. Among these 110 patients, 77 patients were enrolled in this study within 1 month from the decision for HSCT. Among these 77 patients, 13 patients had a human leukocyte antigen (HLA)-matched sibling, 54 patients started an unrelated donor search, and the other 10 patients directly selected cord blood (CB) at the decision for HSCT, and 13 (100%), 38 (70.4%), and 9 (90%) patients actually underwent HSCT within 1 year, respectively. The overall survival (OS) at 1 year from their enrollment was 70.9%, and the selection of azacitidine use at the decision for HSCT was not associated with OS. Among 60 of the 77 patients who actually underwent HSCT within a year from their enrollment, a lower relapse rate after HSCT was observed in those who selected CB at the decision to undergo HSCT. However, this preferable effect of CB selection disappeared when patients who were enrolled in this study in > 1 month from the decision for HSCT were additionally included in the analyses. In conclusion, the selection of bridge strategy at the decision for HSCT did not affect outcomes in patients with MDS. The immediate performance of HSCT may be associated with better outcomes.

    Abstract The CFA ratio, calculated using pretreatment C-reactive protein (CRP), fibrinogen, and albumin levels (CRP × fibrinogen/albumin), was previously reported to be a significant prognostic factor for acute myeloid leukemia (AML). This multicenter retrospective study evaluated the prognostic value of the CFA ratio in 328 adult patients with newly diagnosed AML from April 2000 to March 2018. The median age was 49.5 years (range, 15-75 years), and 60.7% of the population were males. According to the European LeukemiaNet (ELN) risk classification, 67 patients (20.4%) were in the favorable-risk group, 197 patients (60.1%) in the intermediate-risk group, and 58 patients (17.7%) in the adverse-risk group. The median CFA ratio was 1.07 (0-67.69). Based on the calculated cutoff CFA ratio of 1.44, the cohort included 176 and 152 patients with low and high CFA ratios, respectively. At a median follow-up of 91.2 months, the 7-year overall survival (OS) and disease-free survival (DFS) rates were 51.2% and 48.6%, respectively, in the overall cohort. The 7-year OS rates were 61.7% and 39.0% in the low and high CFA ratio groups, respectively (p < 0.001). The 7-year DFS rates were 58.1% and 37.0% in the low and high CFA ratio groups, respectively (p = 0.004). In univariate analysis, age ≥50 years, male sex, ELN risk class, and comorbidities were associated with poor OS. Age, ELN risk class, comorbidities, and high CFA ratio were associated with poor OS in multivariate analysis. Subgroup analysis revealed that the CFA ratio was significant in the intermediate and adverse ELN risk classes. These findings indicate the prognostic significance of the CFA ratio in AML.

    Abstract Smoking is associated with a high risk for different diseases including respiratory tract infections in immunocompetent patients. However, data about the effects of cigarette smoking on the outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) are limited. Therefore, we retrospectively investigated 608 patients aged ≥20 years with hematological disorders who received their first allo-HSCT at our group of hospitals between 2000 and 2015, and evaluated the impact of cigarette smoking before allo-HSCT on clinical outcomes by dividing patients into two groups according to the Brinkman index (BI) (nonsmokers or light smokers [BI: 0-500] and heavy smokers [BI: ≥ 500]). Multivariate analyses showed that heavy smoking was associated with a high 5-year cumulative incidence of chronic graft-versus-host disease (cGVHD) (hazard ratio [HR]: 1.73, 95% confidence interval [CI]: 1.15-2.61, p < 0.01). The 5-year overall survival (HR: 1.16, 95% CI: 0.86-1.58, p = 0.33) and disease-free survival (HR: 1.12, 95% CI: 0.83-1.52, p = 0.45) were similar between the two groups. Hence, cigarette smoking is correlated with cGVHD, although prospective studies must be conducted to further verify this result.
