    Abstract Chimeric Antigen Receptor T-cell (CAR T-cell) therapy is an effective treatment for relapsed/refractory (R/R) large B cell lymphoma (LBCL). However, patients with central nervous system (CNS) lymphoma were excluded in most of the CAR T-cell therapy trials. This meta-analysis assesses the efficacy with CAR T-cell therapy in LBCL patients with CNS involvement. Two reviewers independently searched PubMed and Cochrane Library to identify all published literature associated with United States Food and Drug Administration approved CAR T-cell therapies for LBCL. Patients with CNS LBCL were included. Meta-analysis of proportion was performed to evaluate the overall response (ORR), complete response (CR) for efficacy, and cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome for safety assessment. Nineteen studies were qualified for inclusion with 141 CNS LBCL patients. The ORR and CR rates were 61% and 55% respectively. The median overall survival (OS) was 8.8 months, and the median progression free survival (PFS) was 4.4 months. Severe immune effector cell-associated neurotoxicity syndrome (grade≥3) were reported in 25% (32/130) patients and severe cytokine release syndrome (grade≥3) were found in 10% (13/124) of the patients. The safety and efficacy of CAR T-cell therapy in CNS LBCL patients appears comparable to patients without CNS involvement.

    Abstract Ovarian dysfunction is an important consequence of hematopoietic stem cell transplantation (HCT). Premature ovarian failure and infertility can severely impact the quality of life for the increasing number of female long-term survivors of HCT. Here, we review the impact of HCT on ovarian function, post-transplant fertility and birth outcomes, and the contemporaneous strategies to preserve fertility for these patients.

    Abstract Allogeneic hematopoietic stem cell transplantation (HSCT) provides the only potentially curative option for multiple hematological conditions. However, allogeneic HSCT outcomes rely on an optimal balance of effective immune recovery, minimal graft-versus-host disease (GVHD), and lasting control of disease. The quest to attain this balance has proven challenging over the past few decades. The two-step approach to HSCT was conceptualized and pioneered at Thomas Jefferson University in 2005 and remains the main platform for allografting at our institution. Following administration of the transplant conditioning regimen, patients receive a fixed dose of donor CD3+ cells (HSCT step one-DLI) as the lymphoid portion of the graft on day -6 with the aim of optimizing and controlling T cell dosing. Cyclophosphamide (CY) is administered after the DLI (days -3 and -2) to induce donor-recipient bidirectional tolerance. On day 0, a CD34-selected stem cell graft is given as the myeloid portion of the graft (step two). In this two-step approach, the stem cell graft is infused after CY tolerization, which avoids exposure of the stem cells to an alkylating agent, allowing rapid count recovery. Here, the two-step platform is described with a focus on key results from studies over the past two decades. Finally, this review details lessons learned and current strategies to optimize the graft-versus-tumor effect and limit transplant-related toxicities.

    Abstract Posttransplant lymphoproliferative disorder (PTLD) includes a range of abnormal lymphoid proliferation following solid organ or allogeneic hematopoietic stem cell transplantation (HSCT), often associated with Epstein-Barr virus (EBV) infection. Treatment generally incudes rituximab, a chimeric monoclonal antibody directed against CD20. Here we present a 56-year-old woman with EBV-associated PTLD following allogeneic HSCT who was intolerant of rituximab. The patient was instead treated with ofatumumab, a fully human monoclonal antibody directed against CD20, with significant response in EBV viral load and lymphadenopathy. Ofatumumab could represent an important treatment option for patients unable to tolerate rituximab.

    Abstract Engraftment syndrome (ES) is associated with neutrophil recovery after stem cell transplantation (SCT). It is associated with autologous and allogeneic SCT. However, a literature review has shown that allogeneic SCT (allo-SCT) is associated with ES without conclusive data on risk factors or effects on outcomes. This meta-analysis was undertaken to estimate the cumulative incidence of ES following allo-SCT, and to evaluate the risk factors and outcomes among patients with ES following allo-SCT. Current literature was searched using electronic databases, and manually. Studies with ES after allo-SCT were selected, and a meta-analysis of proportion was performed using the Freeman-Tukey Double Arcsine transformation, random-effects model to calculate the cumulative incidence of ES. Donor type, source of haematopoetic stem cells, graft vs. host disease (GvHD) prophylaxes, and conditioning regimens' intensity were evaluated for risk factors for ES. Association of acute GvHD (aGvHD), chronic GvHD (cGvHD), relapse, nonrelapse mortality (NRM), and overall survival (OS) between the ES and no ES groups were assessed using the odds ratio (OR). Eighteen studies were included comprising 3620 patients receiving allo-SCT and 774 of them had developed ES with a cumulative incidence of 35.4%. The odds of aGvHD (OR 2.5, p < 0.001), cGvHD (OR 4.5, p = 0.021), and NRM (OR 1.8, p = 0.01) were higher among patients who developed ES. The odds of relapse were significantly less (OR = 0.679, p = 0.011) among the ES group. OS (OR = 0.72, p < 0.001) was reduced in the ES group. Myeloablative conditioning was found to be a significant risk factor for ES development. In conclusion, ES after allo-SCT is common with higher odds of developing aGvHD, cGvHD, and NRM and lower odds of OS.

    Abstract The majority of contemporary allogeneic hematopoietic stem cell transplantation (HCT) procedures utilize partially HLA-mismatched stem cell grafts. Donor-specific anti-HLA antibodies (DSA) are associated with primary graft failure independent of the graft source, conditioning intensity and other patient and donor factors. Here we provide an update on testing and monitoring of DSA, review the impact of DSA on stem cell engraftment, and present promising desensitization modalities. Ultimately, we attempt to provide practical recommendations for DSA screening and mitigation strategies.

    Abstract Acute graft versus host disease (aGVHD) was first described by Barnes et al. in 1962, who reported a 'secondary disease' in mice after irradiation and infusion of allogeneic spleen cells. The disease manifested as fatal diarrhea and skin abnormalities. They postulated that aGVHD resulted from introducing immunologically competent cells into an immunocompetent host. Treatments were developed to address this problem, and most centers use calcineurin inhibitors (tacrolimus or cyclosporine) combined with mycophenolate mofetil or methotrexate to prevents aGVHD. This classic GVHD prophylaxis is associated with an incidence of acute GVHD of approximately sixty percent. Other methods of GVHD prevention, including T-cell depletion and more recently post-trasnplant cyclophosphamid, have been tested, but all have their own limitations. The most effective methods tend to be more immunosuppressive and are not clearly superior in regards to long-term survival. Acute GVHD then remains a major problem in hematopoietic stem cell allogeneic transplantation (HCT). Its initial treatment consists of high-dose glucocorticosteroids (1-2 mg/kg daily). However, only one-third of patients are cured, leaving the majority of patients requiring more therapy. Patients with glucocorticosteroid refractory acute GVHD (SR aGVHD) have a very high mortality and to date, there is no effective treatment.
