Molecular Features and Treatment Paradigms of Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a common hematologic malignancy that is considered to be a disease of aging, and traditionally has been treated with induction chemotherapy, followed by consolidation chemotherapy and/or allogenic hematopoietic stem cell transplantation. More recently, with the use of next-generation sequencing and access to molecular information, targeted molecular approaches to the treatment of AML have been adopted. Molecular targeting is gaining prominence, as AML mostly afflicts the elderly population, who often cannot tolerate traditional chemotherapy.

Impact of Palliative Care Referral on End-of-Life Outcomes for Patients With Hematologic Malignancy.

Context: Compared to patients with solid malignancies, less is known about the role of palliative care in patients with hematologic malignancies, leading to underutilization of palliative care.

Objectives: Evaluate the timing and impact of palliative care referrals on end-of-life outcomes over a 5-year period with intent to improve the utilization of palliative care in patients with advanced hematologic malignancies.

Methods: A retrospective cohort of patients from an urban, NCI-designated comprehensive cancer center, aged 18 years and older with a diagnosis of an advanced hematologic malignancy were separated into groups of early, late, very late, or no specialty palliative care.

Leukemia Cutis in Relapsed Acute Myeloid Leukemia: A Call for Distinct Classification.

BACKGROUND Acute myeloid leukemia is characterized by dysregulated proliferation and maturation arrest of myeloid precursors, precipitating a spectrum of complications. Among these, leukemia cutis refers specifically to ectopic deposition and proliferation of malignant myeloid cells within the skin. This infiltration pathogenesis remains unclear.

Single agent subcutaneous blinatumomab for advanced acute lymphoblastic leukemia.

Blinatumomab is a BiTE® (bispecific T-cell engager) molecule that redirects CD3 T-cells to engage and lyse CD19 target cells. Here we demonstrate that subcutaneous (SC) blinatumomab can provide high efficacy and greater convenience of administration. In the expansion phase of a multi-institutional phase 1b trial (ClinicalTrials.

Acute Myeloid Leukemia Treatment in the Elderly: A Comprehensive Review of the Present and Future.

Background: Acute myeloid leukemia (AML) is a disease of the hematopoietic system that remains a therapeutic challenge despite advances in our understanding of the underlying cancer biology in the past decade. It is also an affliction of the elderly that predominantly affects patients over 60 years of age. Standard therapy involves intensive chemotherapy that is often difficult to tolerate in older populations.

Large granular lymphocytic leukemia cured by allogeneic stem cell transplant: a case report.

Background: Large granular lymphocytic leukemia is a rare lymphocytic neoplasm that can pose a treatment challenge in patients with severe neutropenia in whom conventional therapies fail. We report one of the first cases in which allogeneic stem cell therapy was used as treatment for large granular lymphocytic leukemia. We report and discuss the case of a 42-year-old white Caucasian female who, despite multiple therapies including methotrexate, cyclophosphamide, prednisone, cyclosporine, and pentostatin, continued to show severe neutropenia and recurrent infections.

Pulmonary Toxic Effects After Myeloablative Conditioning With Total Body Irradiation Delivered via Volumetric Modulated Arc Therapy With Fludarabine.

We present the case of a 56-year-old female with a diagnosis of acute T-cell lymphoblastic leukemia who received myeloablative conditioning for bone marrow transplant with total body irradiation (TBI) using volumetric modulated arc therapy (VMAT) to the upper body and anterior-posterior/posterior-anterior (AP/PA) open fields to the lower body followed by hematopoietic stem cell transplant. Her clinical course was complicated by high-grade pulmonary toxic effects 55 days after treatment that resulted in death. We discuss the case, planning considerations by radiation oncologists and radiation physicists, and the multidisciplinary medical management of this patient.

Prescreening to Increase Therapeutic Oncology Trial Enrollment at the Largest Public Hospital in the United States.

Purpose: The recruitment of underserved patients into therapeutic oncology trials is imperative. The National Institutes of Health mandates the inclusion of minorities in clinical research, although their participation remains under-represented. Institutions have used data mining to match patients to clinical trials.

Post-transplantation Cyclophosphamide: From HLA-Haploidentical to Matched-Related and Matched-Unrelated Donor Blood and Marrow Transplantation.

Following allogeneic blood and marrow transplantation (BMT), graft-versus-host disease (GvHD) continues to represent a significant cause of treatment failure, despite the routine use of conventional, mainly calcineurin inhibitor-based prophylaxis. Recently, post-transplant cyclophosphamide (PTCy) has emerged as a safe and efficacious alternative. First, omitting the need for T-cell depletion in the setting of haploidentical transplantation, growing evidence supports PTCy role in GvHD prevention in matched-related and matched-unrelated transplants.

Haploidentical Hematopoietic Stem Cell Transplantation Followed by 'Post-Cyclophosphamide': The Future of Allogeneic Stem Cell Transplant.

Allogeneic hematopoietic cell transplant (Allo-HCT) is a potentially curative therapy for many malignant and nonmalignant hematological diseases. However, a suitable human leukocyte antigens (HLAs)-matched donor may not be available when the patient is in urgent need of a stem cell transplant. This challenge has been ameliorated to a large extent by the introduction of haploidentical donors.

Current Status and Future Directions in Graft--Host Disease Prevention Following Allogeneic Blood and Marrow Transplantation in Adults.

Graft--host disease (GvHD) in its acute and chronic forms continues to represent a significant barrier to the success and wide-applicability of blood and marrow transplantation as a potentially curative treatment modality for a number of benign and malignant blood conditions. Presently, calcineurin inhibitor (CNI)-based regimens remain the most commonly used prevention strategy, although post-transplant cyclophosphamide is emerging as an alternative approach, and is providing a backbone for innovative CNI-free combinations. In this paper, we review the current strategies used for the prevention of GvHD, and highlight some of the developing and promising combinations.

Human Herpes Virus-6 Encephalitis Following Autologous Blood and Marrow Transplant.

Human herpesvirus-6 (HHV-6) is a highly prevalent virus that establishes lifelong latency in human hosts. Symptomatic HHV-6 reactivation rarely occurs in immunocompetent individuals and is best described in immunosuppressed patients such as recipients of bone marrow transplants (BMT). In that setting, HHV-6 reactivation has been associated with fever, rash, pneumonitis, encephalitis, and delayed engraftment.

Assessment of the Safety of Pembrolizumab in Patients With HIV and Advanced Cancer-A Phase 1 Study.

Importance: Anti-PD-1 (anti-programmed cell death 1) and anti-PD-L1 (anti-programmed cell death ligand 1) regimens are preferred therapies for many cancers, including cancers associated with HIV. However, patients with HIV were excluded from most registered trials.

Objective: The primary objective was to evaluate the safety of pembrolizumab in people with HIV and advanced cancer; the secondary objective was to evaluate tumor responses.

Primary extramedullary plasmacytoma with diffuse lymph node involvement: a case report and review of the literature.

Background: Primary plasmacytomas are localized proliferations of clonal plasma cells occurring in the absence of a systemic plasma cell dyscrasia such as multiple myeloma. Primary plasmacytomas most commonly manifest as solitary lesions of the bone or of the upper aerodigestive tract. Presentation in a lymph node is very uncommon and can often be initially mistaken for lymphoma.

A Challenging Blastic Plasmacytoid Dendritic Cell Neoplasm Case: Tough Decisions to Make.

Blastic plasmacytoid dendritic cell neoplasm is a very rare disease and in our case report we discuss the presentation of our patient, her treatment and response in addition for a discussion of the newly therapeutic options that are available.

T-cell lymphomas, a challenging disease: types, treatments, and future.

T-cell lymphomas are rare and aggressive malignancies associated with poor outcome, often because of the development of resistance in the lymphoma against chemotherapy as well as intolerance in patients to the established and toxic chemotherapy regimens. In this review article, we discuss the epidemiology, pathophysiology, current standard of care, and future treatments of common types of T-cell lymphomas, including adult T-cell leukemia/lymphoma, angioimmunoblastic T-cell lymphoma, anaplastic large-cell lymphoma, aggressive NK/T-cell lymphoma, and cutaneous T-cell lymphoma.

Novel agents in the treatment of multiple myeloma: a review about the future.

Multiple myeloma (MM) is a disease that affects plasma cells and can lead to devastating clinical features such as anemia, lytic bone lesions, hypercalcemia, and renal disease. An enhanced understanding of MM disease mechanisms has led to new more targeted treatments. There is now a plethora of treatments available for MM.

A Synthetic Lethal Interaction between Glutathione Synthesis and Mitochondrial Reactive Oxygen Species Provides a Tumor-Specific Vulnerability Dependent on STAT3.

Increased production of mitochondrion-derived reactive oxygen species (ROS) is characteristic of a metabolic shift observed during malignant transformation. While the exact sources and roles of ROS in tumorigenesis remain to be defined, it has become clear that maintaining redox balance is critical for cancer cell proliferation and survival and, as such, may represent a vulnerability that can be exploited therapeutically. STAT3, a latent cytosolic transcription factor activated by diverse cytokines and growth factors, has been shown to exhibit an additional, nontranscriptional function in mitochondria, including modulation of electron transport chain activity.

Novel agents in the treatment of chronic lymphocytic leukemia: a review about the future.

Half of a century ago, physicians managing chronic lymphocytic leukemia (CLL) recognized some of its presenting features such as lymphocytosis, lymphadenopathy, and splenomegaly. Subsequently, an enhanced understanding of the disease mechanisms involved in CLL led to new, more targeted treatments. There is now a plethora of treatments available for CLL.
