Based on these criteria, a risk score model was developed and validated to estimate the probability of AC following allo-HSCT. selleck chemicals The model separates all patients into low-, intermediate-, and high-risk groups and thereby provides a basis for early detection of this complication in the management of allo-HSCT.The predictive value of measurable residual disease (MRD) for survival in acute myeloid leukemia (AML) has been firmly established in younger patients treated with intensive chemotherapy. The value of MRD after treatment with decitabine in older patients is unknown. This retrospective analysis included patients ≥60 years of age with AML who received an allogeneic hematopoietic cell transplantation (alloHCT) after treatment with decitabine or intensive chemotherapy. Of the 133 consecutively transplanted patients, 109 had available pretransplantation MRD analyses (by flowcytometry [threshold 0.1%]). Forty patients received decitabine treatment (10-day schedule), and 69 patients received intensive chemotherapy (7 + 3 regimen). Patients who received decitabine were older (median 67 versus 64 years) and more often had MRD (70% versus 38%). OS after alloHCT was comparable in both groups. In the chemotherapy group, MRD-positive patients had a significantly higher relapse probability (subdistribution hazard ratio [sHR] 4.81; P= .0031) and risk of death (HR 2.8; P= .02) compared to MRD-negative patients. In the decitabine group there was no significant association between the presence of MRD and relapse (sHR 0.85; P= .83) or death (HR 0.72; P= .60). Pretransplantation MRD in patients receiving decitabine treatment does not have similar predictive value for relapse or survival in older AML patients receiving an alloHCT, compared to patients receiving intensive chemotherapy.The optimal stem cell (SC) mobilization strategy for patients with multiple myeloma (MM) remains a matter of debate. Possible approaches include low or high doses of cyclophosphamide (Cy), other chemotherapeutic agents, or granulocyte colony-stimulating factor (G-CSF) alone. The scope of the study was to compare low-dose Cy plus G-CSF versus intermediate-high-dose Cy plus G-CSF versus G-CSF alone for SC mobilization in MM, in terms of efficacy and safety. We retrospectively analyzed 422 MM patients undergoing SC mobilization in 6 Italian centers, including 188 patients who received low-dose Cy (LD-Cy group, defined as 2 g/m2), 163 patients who received intermediate-high-dose Cy (HD-Cy group, defined as ≥ 3 g/m2), and 71 patients who received G-CSF alone (G-CSF group). The median peak of circulating CD34+ cells was 77/µL in the LD-Cy group, 92/µL in the HD-Cy group, and 55/µL in the G-CSF group (P = .0001). The median amount of SCs collected was 9.1 × 106/kg, 9.7 × 106/kg, and 5.6 × 106/kg in the 3 groups, respectively (P = .0001). The rate of mobilization failure (defined as failure to collect ≥2 × 106/kg) was 3.7% in the LD-Cy group, 3.4% in the HD-Cy group, and 4.3% in the G-CSF group (P = .9). The target SC dose of at least 4 × 106/kg was reached in 90.4%, 91.1%, and 78.6% of the patients in these 3 groups, respectively (P = .014). The "on demand" use of plerixafor was higher in the G-CSF group (76%) compared with the LD-Cy group (19%) and the HD-Cy group (6%). In multivariate analysis, G-CSF mobilization and previous use of melphalan or radiotherapy were independently associated with failure to collect the target SC dose of ≥4 × 106/kg. No impacts of age, blood counts, or previous treatment with lenalidomide, bortezomib, or carfilzomib were observed. Our results suggest that LD-Cy may be considered for successful SC mobilization in patients with MM.Numerous genetic abnormalities affect treatment outcomes in multiple myeloma. The role of coexistent trisomy or hyperdiploidy and high-risk cytogenetic abnormalities (CGAs) is not well defined. We assessed the influence of overlapping genetic abnormalities in patients who received frontline autologous stem cell transplantation. A total of 491 consecutive patients between January 2009 and January 2016 were identified. High-risk CGAs included del(17p), t(4;14), t(14;16), and gain 1q21 by fluorescence in situ hybridization and del(13) by conventional cytogenetics. Thirty-two percent had a trisomy, 27% had a high-risk CGA, and 11% had both. Among patients with any trisomy, 3-year progression-free survival (PFS) and overall survival (OS) were 60% and 90%, respectively, compared to 25% and 65%, respectively, for patients with any high-risk CGA. Patients with co-existent trisomy and high-risk CGAs had 3-year PFS and OS of 43% and 89%, respectively, whereas those with isolated high-risk CGAs without trisomy had 3-year PFS and OS of 13% and 49%, respectively. The PFS (hazard ratio [HR], 1.9; 95% confidence interval [CI], 1.1 to 3.3; P = .02) and OS (HR, 4.5; 95% CI, 1.5 to 13; P = .006) were worse for high-risk CGAs without versus those with concurrent trisomies. Our findings suggest a protective impact of trisomies in patients with high-risk CGAs and a potential need for revised risk stratification assessments to account for overlapping genetic abnormalities.In patients with lymphoma, third-space fluid accumulations may develop or worsen during cytokine release syndrome (CRS) associated with chimeric antigen receptor (CAR) T cell therapy. Pre-existing symptomatic pleural effusions were excluded by the ZUMA-1 trial of axicabtagene ciloleucel for large B cell lymphoma (LBCL) and variants. The incidence and management of effusions during CAR T cell therapy for LBCL are unknown. We performed a single-center retrospective study evaluating 148 patients receiving CD19-directed CAR T cell therapy for LBCL between May 2015 and September 2019. We retrospectively identified patients who had radiographic pleural, pericardial, or peritoneal effusions that were present prior to the time of CAR T infusion (pre-CAR T) or that newly developed during the first 30 days after CAR T-cell infusion (post-CAR T). Of 148 patients, 19 patients had a pre-CAR T effusion, 17 patients without pre-existing effusion developed a new infusion after CAR T, and 112 patients had no effusions. Comparfusions commonly complicate CAR T cell therapy for lymphoma. Malignant effusions that occur prior to CAR T therapy are frequently persistent and require therapeutic intervention, and patients have a higher rate of toxicity and death. Effusions that newly occur after CAR T therapy can generally be managed medically and tend not to persist.Until recently, treatment options were relatively limited for children and young adults with relapsed or refractory (r/r) acute lymphoblastic leukemia (ALL). Tisagenlecleucel is a chimeric antigen receptor T cell (CAR-T) immunotherapy with promising efficacy and manageable safety that was approved in Japan in 2019 for the treatment of CD19-positive r/r B cell ALL (B-ALL). However, there is no publication assessing the cost-effectiveness of CAR-T in Japan. The objective of this study was to assess the cost-effectiveness of a tisagenlecleucel treatment strategy compared to a blinatumomab treatment strategy and a clofarabine combination treatment strategy (i.e., clofarabine + cyclophosphamide + etoposide) in Japan for pediatric and young adult patients up to 25 years of age with r/r B-ALL. A partitioned survival model with a lifetime horizon and monthly cycle was constructed from a Japanese public healthcare payer's perspective. Patients were distributed across the following partitioned health states event-free costs, and terminal care costs. Incremental cost-effectiveness ratios (ICERs) per life-years (LYs) gained and ICERs per quality-adjusted life-years (QALYs) gained were evaluated using a 2% discount rate, and a threshold of ¥7.5 million was used to assess cost-effectiveness. Deterministic and probabilistic sensitivity analyses were performed. The total LYs (discounted) for tisagenlecleucel, blinatumomab, and clofarabine combination treatment strategies were 13.3, 4.0, and 2.7 years, respectively; the corresponding QALYs were 11.6, 3.1, and 2.1 years, respectively. The ICERs per QALY gained for tisagenlecleucel were ¥2,035,071 versus blinatumomab and ¥2,644,702 versus clofarabine combination therapy. Extensive sensitivity analyses supported the findings. Tisagenlecleucel is a cost-effective treatment strategy for pediatric and young adult patients with r/r B-ALL from a Japanese public healthcare payer's perspective.CD19-targeted chimeric antigen receptor (CAR) T cells have shown excellent activity against relapsed and refractory (R/R) diffuse large B cell lymphoma (DLBCL). CAR T cell therapy is associated with early toxicities, including cytokine release syndrome and neurotoxicity. The incidence and severity of these toxicities has been associated in part with baseline disease and patient characteristics, which also may impact overall survival (OS) and progression-free survival (PFS). However, there are limited data on patient selection and how to better predict toxicities or outcomes. Indexes used in patients with DLBCL, such as the International Prognostic Index (IPI and age-adjusted IPI [aaIPI]) and in transplantation recipients, such as the Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI), have not been evaluated in this setting. Here we evaluated 4 indices- IPI, aaIPI, HCT-CI, and the Charlson Comorbidity Index (CCI)-and their associations with early CAR T cell related-toxicities and outcomes. We demonstrated an association between high-risk IPI or aaIPI and inferior PFS in patients with R/R DLBCL treated with CAR T cell therapy. We also found an association between aaIPI and IPI with OS and neurotoxicity, respectively. CCI was not associated with toxicities or outcomes, and owing to the small sample size, we could not draw a conclusion regarding associations with the HCT-CI. Both the IPI and aaIPI are widely used tools that can now provide better information to guide selection of patients who would best benefit from CD19 CAR T cell therapy.Chronic graft-versus-host disease (cGVHD) remains a common threat after allogeneic hematopoietic cell transplantation (allo-HSCT), and ocular manifestations occur in up to 60% to 90% of cGVHD patients. We sought to reveal major metabolic dysregulation and to determine tear metabolites as potential biomarkers for ocular cGVHD. Twenty-three ocular cGVHD and 16 control tear samples were collected for this study. Differential metabolites were identified using a liquid chromatography-mass spectrometry system. Spearman's test was used to analyze the correlation between metabolites and ophthalmic indexes (National Institutes of Health [NIH] eye score, fluorescein tear film break-up time [T-BUT], corneal fluorescein staining [CFS], and Schirmer's test). Receiver operating characteristic (ROC) curve was analyzed to evaluate the prediction potential of identified metabolites for ocular cGVHD. Differential metabolites were mainly observed in lipid metabolites, and we highlighted the lipid dysregulation in glycerophospho as promising tear biomarkers to indicate metabolic dysregulation and ophthalmic manifestations in ocular cGVHD.The Practice Guidelines Committee of the American Society of Transplantation and Cellular Therapy partnered with its Transplant Infectious Disease Special Interest Group to update its 2009 compendium-style infectious disease guidelines for hematopoietic cell transplantation (HCT). A completely fresh approach was taken with the goal of better serving clinical providers by publishing each standalone topic in the infectious disease series as a concise format of frequently asked questions (FAQs), tables, and figures. Adult and pediatric infectious disease and HCT content experts developed, then answered FAQs, and finalized topics with harmonized recommendations that were made by assigning an A through E strength of recommendation paired with a level of supporting evidence graded I through III. This second guideline in the series focuses on invasive aspergillosis, a potentially life-threatening infection in the peri-HCT period. The relevant risk factors, diagnostic considerations, and prophylaxis and treatment approaches are reviewed.
