Role of allogeneic hematopoietic cell transplantation in VEXAS syndrome.

VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) is a newly diagnosed syndrome comprising severe systemic inflammatory and hematological manifestations including myelodysplastic syndrome and plasma cell dyscrasia. Since its discovery four years ago, several groups have identified pleomorphic clinical phenotypes, but few effective medical therapies exist which include Janus Kinase (JAK) inhibitors, interleukin inhibitors (IL-1 and IL-6), and hypomethylating agents. Prospective trials are lacking at this time and most patients remain corticosteroid dependent.

Cytogenetically cryptic PML::RARA fusion in acute promyelocytic leukemia: Testing strategies in the modern era.

Acute promyelocytic leukemia (APL) is a unique leukemia that is characterized by the fusion. This fusion is often detected by conventional karyotype and fluorescence in situ hybridization (FISH); however, rare cases are cryptic and require molecular techniques to identify the fusion. Furthermore, as the incidence of these cases is rare, analysis by a targeted next-generation sequencing (NGS) panel of myeloid associated genes has never been reported.

Demographic differences among patients treated with chimeric antigen receptor T-cell therapy in the United States.

Background: It is not clear if all Americans have benefitted equally from the availability of chimeric antigen receptor T-cell (CART) therapy. We aimed to evaluate if demographic differences existed among adult patients who received CART therapy and to assess predictors of CART treatment outcomes.

Methods: Records of patients ≥18 years who received CART therapy for non-Hodgkin's lymphoma, acute lymphoblastic leukemia, and multiple myeloma in 2018 were evaluated in the National Inpatient Sample.

Male-specific late effects in adult hematopoietic cell transplantation recipients: a systematic review from the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation.

Male-specific late effects after hematopoietic cell transplantation (HCT) include genital chronic graft-versus-host disease (GvHD), hypogonadism, sexual dysfunction, infertility, and subsequent malignancies. They may be closely intertwined and cause prolonged morbidity and decreased quality of life after HCT. We provide a systematic review of male-specific late effects in a collaboration between transplant physicians, endocrinologists, urologists, dermatologists, and sexual health professionals through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research, and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation.

Male-Specific Late Effects in Adult Hematopoietic Cell Transplantation Recipients: A Systematic Review from the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation.

Male-specific late effects after hematopoietic cell transplantation (HCT) include genital chronic graft-versus-host disease (GVHD), hypogonadism, sexual dysfunction, infertility, and subsequent malignancies, such as prostate, penile, and testicular cancer. These effects may be closely intertwined and cause prolonged morbidity and decreased quality of life after HCT. Here we provide a systematic review of male-specific late effects in a collaboration among transplantation physicians, endocrinologists, urologists, dermatologists, and sexual health professionals through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation.

Return to Work Among Young Adult Survivors of Allogeneic Hematopoietic Cell Transplantation in the United States.

Young adult (YA) survivors of allogeneic hematopoietic cell transplantation (HCT) are at risk for late psychosocial challenges, including the inability to return to work post-HCT. Work-related outcomes in this population remain understudied, however. We conducted this study to assess the post-HCT work status of survivors of allogeneic HCT who underwent HCT as YAs and to analyze the patient-, disease-, and HCT-related factors associated with their work status at 1 year post-HCT.

Impact of depth of clinical response on outcomes of acute myeloid leukemia patients in first complete remission who undergo allogeneic hematopoietic cell transplantation.

Acute myeloid leukemia (AML) patients often undergo allogeneic hematopoietic cell transplantation (alloHCT) in first complete remission (CR). We examined the effect of depth of clinical response, including incomplete count recovery (CRi) and/or measurable residual disease (MRD), in patients from the Center for International Blood and Marrow Transplantation Research (CIBMTR) registry. We identified 2492 adult patients (1799 CR and 693 CRi) who underwent alloHCT between January 1, 2007 and December 31, 2015.

Impact of Pretransplantation Renal Dysfunction on Outcomes after Allogeneic Hematopoietic Cell Transplantation.

Renal dysfunction is a recognized risk factor for mortality after allogeneic hematopoietic cell transplantation (alloHCT), yet our understanding of the effect of different levels of renal dysfunction at time of transplantation on outcomes remains limited. This study explores the impact of different degrees of renal dysfunction on HCT outcomes and examines whether the utilization of incremental degrees of renal dysfunction based on estimated glomerular filtration rate (eGFR) improve the predictability of the hematopoietic cell transplantation comorbidity index (HCT-CI). The study population included 2 cohorts: cohort 1, comprising patients age ≥40 years who underwent alloHCT for treatment of hematologic malignancies between 2008 and 2016 (n = 13,505; cohort selected given a very low incidence of renal dysfunction in individuals age <40 years), and cohort 2, comprising patients on dialysis at the time of HCT (n = 46).

Acute myeloid leukemia or myelodysplastic syndrome with chromosome 17 abnormalities and long-term outcomes with or without hematopoietic stem cell transplantation.

Introduction: Chromosome 17 abnormalities, especially disorders of the 17p region and including TP53 gene mutations, result in very low rates of cure for patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) treated with conventional chemotherapy or allogeneic hematopoietic cell transplant (allo-HCT). Our retrospective study analyzed outcomes in patients with chromosome 17 (ch17) abnormalities who received conventional chemotherapy followed by allo-HCT versus those who did not receive a transplant. We analyzed whether poor outcomes extend to patients with all types of ch17 abnormalities and the impact of concomitant TP53 gene mutations assessed by next-generation sequencing (NGS) on prognosis.

Utility of Routine Surveillance Imaging for Hodgkin Disease following Autologous Transplant: Experiences from a Single Institution.

Background: Surveillance scans performed after autologous stem cell transplant (auto-HCT) for patients with Hodgkin disease (HD) have no proven survival benefit.

Methods: We studied survival differences among patients with HD after auto-HCT whose recurrences were detected on clinical history and exam, versus those detected on routine surveillance scan.

Results: Among the 98 patients with HD that underwent auto-HCT from 2000 to 2014 at our institution, 30 relapsed, of which 21 were detected radiologically and 9 clinically.

Utility of routine surveillance imaging for diffuse large B-cell lymphoma post autologous transplant: A single center experience.

Surveillance scans after autologous stem cell transplant (auto-HCT) for patients with relapsed/refractory (RR) diffuse large B Cell lymphoma (DLBCL) have no proven survival benefit. We studied survival differences among patients with RR DLBCL post auto-HCT whose recurrences were detected clinically versus with routine surveillance imaging. Among the 139 patients with RR DLBCL that underwent auto-HCT from 2000 to 2014 at our institution, 37 relapsed: 21 clinical and 16 radiological.

Mesenchymal Stromal Cells: What Is the Mechanism in Acute Graft-Versus-Host Disease?

After more than a decade of preclinical and clinical development, therapeutic infusion of mesenchymal stromal cells is now a leading investigational strategy for the treatment of acute graft-versus-host disease (GVHD). While their clinical use continues to expand, it is still unknown which of their immunomodulatory properties contributes most to their therapeutic activity. Herein we describe the proposed mechanisms, focusing on the inhibitory activity of mesenchymal stromal cells (MSCs) at immunologic checkpoints.

Inversion 3 Cytogenetic Abnormality in an Allogeneic Hematopoietic Cell Transplant Recipient Representative of a Donor-Derived Constitutional Abnormality.

Allogeneic hematopoietic cell transplantation (HCT) is an important treatment for many severe hematologic disorders; however, HCT can be associated with significant complications, including organ toxicity, graft-versus-host disease, and relapse. Another serious, but rare, complication is the transmission of hematologic and nonhematologic diseases from the donor to the recipient. With older donors, the risk of an abnormality may be increased.

Phase II Trial on Extending the Maintenance Flushing Interval of Implanted Ports.

Purpose: Retrospective studies suggest that it may be safe to extend the maintenance flushing interval of implanted ports from once every month, as recommended by the manufacturer, to once every 3 months, but no prospective cohort studies have been done specifically assessing the safety and feasibility of this intervention.

Methods: This was a phase II study in oncologic patients who retained a functional port after completion of systemic chemotherapy. Patients enrolled in the study had their port flushed once every 3 months and were observed until completion of five scheduled flushes (one on enrollment and four additional flushes, one every 3 months) or development of any port-related complication, including infections, thrombosis, and occlusions.

Exploring Big Data in Hematological Malignancies: Challenges and Opportunities.

Secondary analysis of large datasets has become a useful alternative to address research questions outside the reach of clinical trials. It is increasingly utilized in hematology and oncology. In this review, we provided an overview of some examples of commonly used large datasets in the USA and described common research themes that can be pursued using such a methodology.

Novel Therapeutic Strategies in Acute Lymphoblastic Leukemia.

Chemotherapy cures only a minority of adult patients with acute lymphoblastic leukemia (ALL). In addition, relapsed ALL has a poor outcome with 5-year survival as low as 7 %. Hence, there is a need to develop effective therapies to treat relapsed disease and to combine these agents with chemotherapy to improve outcomes in newly diagnosed patients.

Type B lactic acidosis: a rare but life threatening hematologic emergency. A case illustration and brief review.

Major strides have been made in improving the treatment of medical emergencies associated with malignancies. Nonetheless, metabolic emergencies in cancer patients can often times be life-threatening. Type B lactic acidosis is a rare but potentially fatal paraneoplastic phenomenon that has been described in association with hematologic and solid malignancies and portends a poor prognosis if not rapidly recognized and treated.

Ibrutinib: a new frontier in the treatment of chronic lymphocytic leukemia by Bruton's tyrosine kinase inhibition.

Chronic lymphocytic leukemia (CLL) is characterized by progressive accumulation of nonfunctional mature B cells in blood, bone marrow and lymphoid tissues. In the last decade, our understanding of CLL and consequently our diagnostic and therapeutic approaches have changed dramatically. Conventional fludarabine based chemotherapy has led to improved disease response and longer survival in young patients with CLL.

Impairment of salivary mucin production resulting in declined salivary viscosity during naproxen administration as a potential link to upper alimentary tract mucosal injury.

Objectives: Nonsteroidal anti-inflammatory drugs (NSAIDs) contribute to the esophageal mucosal injury through its direct topical impact on the luminal aspect of the surface epithelium. Its indirect, systemic impact, however, on salivary component of the esophageal pre-epithelial barrier remains to be explored. Therefore, salivary mucin secretion and viscosity at baseline and during naproxen-placebo, as well as naproxen-rabeprazole, administration were investigated.
