Andrew C Dietz, Alan S Wayne
Relapse of cancer remains one of the primary causes of treatment failure and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). A multitude of approaches have been used in the management of posttransplant relapse. This review focuses on recent data with cellular therapies designed to treat or prevent posttransplant relapse of hematologic malignancies, although many of these therapeutic approaches also have applications to solid tumors and in the nontransplant setting. Currently available cell therapies include second transplant, natural killer cells, monocyte-derived dendritic cell vaccines, and lymphocytes via donor lymphocyte infusion, antigen-primed cytotoxic T lymphocytes, cytokine-induced killer cells, marrow-infiltrating lymphocytes, and chimeric antigen receptor T cells...

BACKGROUND: Outcomes for patients with relapsed or refractory acute myeloid leukemia (AML) are poor. Guadecitabine, a next-generation hypomethylating agent, could be useful in treating such patients. METHODS: In this multicenter, open-label, phase 2 dose-expansion study, AML patients from 10 North American medical centers were first randomized (1:1) to receive subcutaneous guadecitabine at 60 or 90 mg/m2 on 5 consecutive days in each 28-day cycle (5-day regimen)...

Introduction: African Americans experience the highest burden of cancer incidence and mortality in the United States and have been persistently less likely to receive interventional care, even when such care has been proven superior to conservative management by randomized controlled trials. The presence of disparities in access to radiation therapy (RT) for African American cancer patients has rarely been examined in an expansive fashion. Methods and materials: An extensive literature search was performed using the PubMed database to examine studies investigating disparities in RT access for African Americans...

Tumor Lysis Syndrome (TLS) commonly occurs in hematological malignancies, but it is very rare in patients with a solid tumor. In cases of solid tumors, TLS usually occurs spontaneously or after the initiation of anticancer therapy, and it has a high mortality rate. This syndrome consists of a constellation of laboratory findings such as hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia known as laboratory TLS. When clinical complications such as seizures, acute renal failure, and cardiac dysrhythmias occur in patients with laboratory TLS, the syndrome is called clinical TLS...

Adult survivors of acute leukemia in childhood have a higher than expected frequency of obesity, an increased risk for metabolic syndrome and early mortality from cardiovascular disease (CVD). Adipose tissue has been recognized as an endocrine and paracrine organ that secretes various adipokines involved in metabolic regulation and inflammatory processes. Examine inflammatory factors [IL-6 and TNF-] and adipokines (adiponectin, leptin) in addition to body composition and adiposity in cancer survivors who underwent hematopoietic cell transplantation (HCT) during childhood in comparison to sibling controls...

Importance: Locoregional failure for patients with locally advanced bladder cancer (LABC) after radical cystectomy (RC) is common even with chemotherapy and is associated with high morbidity and mortality. Adjuvant radiotherapy (RT) can decrease locoregional failure but has not been studied in the chemotherapy era. Objective: To investigate if adjuvant sequential RT plus chemotherapy can improve locoregional recurrence-free survival (LRFS) compared with adjuvant chemotherapy alone...

BACKGROUND: Chemotherapy-induced thrombocytopenia (CIT) is defined as a peripheral platelet count less than 100×109/L, with or without bleeding in cancer patients receiving myelosuppressive chemotherapy. CIT is a significant medical problem during chemotherapy, and it carries the risk of sub-optimal overall survival and bleeding. Alternative interventions to platelet transfusion are limited. Different stages of preclinical and clinical studies have examined the thrombopoietin receptor agonists (TPO-RAs) for CIT in patients with solid tumours...

BACKGROUND: Comorbidity is prevalent among stroke patients, affecting post-stroke survival. It remains unknown whether comorbidity impacts post-stroke mortality beyond the combined individual effects of stroke and comorbidity. METHODS: Using nationwide Danish databases, we performed a cohort study of 201,691 patients ≥ 18 years-old with incident ischemic stroke, intracerebral or subarachnoid hemorrhage, or unspecified stroke during 1995-2012, and 992,942 adults from the general population, matched to stroke patients by birth year, sex, and individual comorbidities in the Charlson Comorbidity Index...

BACKGROUND: Patients undergoing transcatheter aortic valve replacement (TAVR) are often characterized by risk factors not reflected in conventional risk scores. In this context, little is known about the outcome of patients suffering from an active cancer disease (ACD). The objective was to determine the prevalence, clinical characteristics, perioperative outcomes, and mortality of patients with ACD undergoing TAVR compared to those with a history of cancer (HCD) and controls without known tumor disease...

Hematologic malignancies and solid tumors increase the risk of venous and arterial thrombosis and contribute greatly to patient morbidity and mortality. Thrombosis occurs when the intricate balance of circulating antithrombotic and prothrombotic blood elements are disrupted. In recent years, the interplay between paraneoplastic cells and platelets has become apparent, with a change in platelet phenotype causing dysregulated platelet activity. This review discusses mechanism of thrombosis in cancer, evidence for using drug therapy, and exciting research efforts to understand and hopefully control aberrant thrombotic events in patients with cancer...

Age related alterations in the human blood system occur in B cells, T cells, cells of the innate system, as well as in hematopoietic stem and progenitor cells (HSPCs). Interestingly, age related, reduced genetic diversity can be identified both at the stem cell level, but also independently in B cells and T cells. This reduced diversity is most probably related to somatic mutations, or to changes in the micro-environmental niche. Either process can select for specific clones, or cause repeated evolutionary bottlenecks...

Acute leukemia is the major cause of mortality in hematological malignancies. Despite improvement of survival with current chemotherapies, patients die from the disease or side-effects of treatment. Thus, new therapeutic agents are needed. Frondoside A is a triterpenoid glycoside originally isolated from the sea cucumber, Cucumaria frondosa that has potent antitumor effects in various cancers. The current study investigated the effects of frondoside A in acute leukemia cell lines alone and in combination with drugs used for this malignancy...

REVIEW
Amy Houghtelin, Catherine M Bollard
While progress has been made in the treatment of both hematologic cancers and solid tumors, chemorefractory or relapsed disease often portends a dismal prognosis, and salvage chemotherapy or radiation expose patients to intolerable toxicities and may not be effective. Hematopoietic stem cell transplant offers the promise of cure for many patients, and while mismatched, unrelated or haploidentical donors are increasingly available, the recipients are at higher risk of severe immunosuppression and immune dysregulation due to graft versus host disease...

Fever during chemotherapy-induced neutropenia continues to be a major cause of morbidity and mortality in cancer patients. Mortality depends on the duration and degree of neutropenia, bacteremia, sepsis, performance status, comorbidities and other parameters. The highest mortality rates in cancer patients hospitalized with febrile neutropenia (FN) are observed in those with documented infection. The objectives of the study were to present available tools for risk assessment, to review pathogens causing infections in adult FN patients and to assess outcomes...

Hepatocellular carcinoma (HCC) is one of the most serious cancers, with rapid progression and high mortality. However, chemotherapy of HCC is hindered by multi-drug resistance (MDR). It is urgent, therefore, to explore new approaches for overcoming MDR of HCC cells. Ubenimex, an inhibitor of CD13, has been used as an immuno-enhancer for treating hematological neoplasms and other solid tumors. Here, we demonstrate that Ubenimex can also reverse MDR in the HCC cell lines HepG2/5-FU and Bel7402/5-FU. Ubenimex inhibits the expression of the proto-oncogene, Pim-3, which is accompanied by decreased expression of BCL-2 and BCL-XL, decreased phosphorylation of Bad, and increased tumor apoptosis...
