We analyzed the distribution of tumors and lymphomas of the anterior mediastinum diagnosed between 1997 and 2016 at the National Cancer Center Hospital, Japan. The median age of 283 patients with anterior mediastinal tumors was 48 (range 6-84) years, and 143 (51%) were male. The incidence of tumors was as follows: thymoma, 34%; thymic carcinoma, 16%; primary mediastinal large B-cell lymphoma (PMBL), 13%; germ cell tumors, 10%; classical Hodgkin lymphoma (CHL), 9%; thymic cyst, 7%; metastatic tumors, 3%; T lymphoblastic leukemia/lymphoma (T-LBL), 2%; other lymphomas, 3%; and others, 3%...

A 13-yr-old male addax (Addax nasomaculatus) presented with locally extensive alopecia, slight erythema, and skin thickening on the medial aspect of the left rear leg between the stifle and tarsus. Cutaneous T-cell lymphoma was diagnosed after histopathology and immunohistochemical staining of representative skin-punch biopsies. No treatment was elected, and the addax was euthanized 3 yr later because of poor body condition, chronic dental disease, and confirmed spread of lymphoma to other cutaneous locations...

TK1 is an enzyme involved in DNA synthesis and repair. TK1 is usually found elevated in cancer patients' serum, which makes it a useful tumor proliferation biomarker that strongly correlates with cancer stage, metastatic capabilities, and recurrence risk. In this study, we show that TK1 is upregulated and localizes on the plasma membrane of Burkitt's lymphoma, acute promyelocytic leukemia, T cell leukemia, and acute lymphoblastic leukemia (ALL). Using flow cytometry, we confirmed that TK1 localizes on the surface of Raji, HL60, and Jurkat cell lines and on ALL clinical samples...

We present here the case of a 33-year-old Chinese female patient with synchronous double primary malignant tumors (chronic myeloid leukemia [CML] and classic Hodgkin lymphoma). This patient was admitted to our hospital because of bilateral cervical lymph node enlargement and recurrent fever for 2 weeks. The complete blood cell count revealed white blood cell counts of 18.2×10(9)/L, hemoglobin of 9.6 g/dL, and platelet counts of 1,547×10(9)/L. Chromosome karyotype analysis demonstrated that t(9;22)(q34;q11) was positive in all 20 cells examined...

The pro-inflammatory activity of interleukin 17, which is produced by the IL-23/IL-17 axis, has been associated with the pathogenesis of traumatic brain injury (TBI). The study investigated the potential role of IL-17 in secondary brain injury of TBI in a rat model. Our data showed that the levels of IL-17 increased from 6 h to 7 days and peaked at 3 days, in both the CNS and serum, which were consistent with the severity of secondary brain injury. The IL-23 inhibitor suberoylanilide hydroxamic acid (SAHA) treatment markedly decreased the expressions of IL-17 and apoptosis-associated proteins cleaved caspase-3 and increased the protein ratio of Bcl-2 (B cell lymphoma/leukemia-2)/Bax (Bcl-2-associated X protein)...

The C - X - C chemokine receptor 4 (CXCR4) and its natural ligand CXCL12 are key factors in the process of cell migration, homing of hematopoietic stem cells to the bone marrow, and represent important mediators of angiogenesis and cell proliferation. The CXCR4/CXCL12 interplay can be disrupted by CXCR4 antagonists such as Plerixafor which are already in daily clinical use, i.e. for mobilization and subsequent harvesting of hematopoietic progenitor cells and stem cell transplantation. In a pathological condition, involvement in the process of metastasis and homing of cancer cells to a protective niche has been described, making CXCR4 an attractive target for imaging and treatment of malignant diseases...

The aim of the present study was to examine the apoptotic effect of cordycepin (COR) on human THP-1 acute monocytic leukemia cells. THP-1 cells were exposed to different concentrations of COR for 24, 48, 72 or 96 h. The cell viability and apoptotic rate were analyzed. The gene expression of Akt1, Akt2, Akt3, B-cell lymphoma 2 (Bcl-2) and Bcl-2-associated X protein (Bax) were assessed by reverse-transcription quantitative PCR. Western blot analysis was used to detect the protein levels of phosphorylated (p)-Akt, p-extracellular signal-regulated kinase (ERK) and cleaved caspase-3...

Treatment intensification to maximize disease control and reduced-intensity approaches to minimize the risk of late sequelae have been evaluated in newly diagnosed Hodgkin lymphoma. The influence of these interventions on the risk of secondary malignant neoplasms, progression-free survival and overall survival is reported in the present meta-analysis based on individual patient data from 9498 patients treated within 16 randomized controlled trials for newly diagnosed Hodgkin lymphoma between 1984 and 2007. Secondary malignant neoplasms were meta-analyzed using Peto's method as time-to-event outcomes...

Human T-cell leukemia virus type-1 (HTLV-1) causes two distinct diseases, adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Since there are no disease-specific differences among HTLV-1 strains, the etiological mechanisms separating these respective lymphoproliferative and inflammatory diseases are not well understood. In this study, by using IL-2-dependent HTLV-1-infected T-cell lines (ILTs) established from patients with ATL and HAM/TSP, we demonstrate that the anti-inflammatory cytokine IL-10 and its downstream signals potentially act as a switch for proliferation in HTLV-1-infected cells...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive hematologic malignancy characterized by frequent skin involvement that most commonly affects older patients. BPDCN is known to have a poor prognosis. Our objective was to assess if outcome and disease prognosis were independently influenced by age when evaluated with clinical presentation, sex, and treatment regimens. We conducted a systematic review to identify BPDCN cases, to compare pediatric BPDCN cases with adult cases. A total of 125 publications were identified detailing 356 cases...

Doxorubicin (DOX) is the most effective chemotherapeutic drug developed against broad range of cancers such as solid tumors, transplantable leukemias and lymphomas. Conventional DOX induced cardiotoxicity has limited its use. FDA approved drugs i.e. non-pegylated liposomal (Myocet®) and pegylated liposomal (Doxil®) formulations have no doubt shown comparatively reduced cardiotoxicity, but has raised new toxicity issues. The entrapment of doxorubicin in biocompatible, biodegradable and safe nano delivery systems can prevent its degradation in circulation minimizing its toxicity with increased half life, enhanced pharmacokinetic profile leading to improved patient compliance...

Adult T-cell leukemia-lymphoma (ATL) is a mature T-cell malignancy associated with human T-cell leukemia virus type I (HTLV-1) infection. Japan is the most endemic country for HTLV-1 and ATL in the world. Recent nationwide studies of Japanese blood donors reported that HTLV-1 carriers spread from endemic areas to non-endemic areas. Therefore, the latest information on nationwide epidemiological and clinical data for ATL is necessary to guide clinical practice. We conducted a multicenter, hospital-based survey of newly diagnosed ATL patients from 2010 to 2011...

The epidemiology and outcomes of tumor lysis syndrome (TLS) are understudied. We used the National Inpatient Sample (NIS), a nationally representative weighted sample of all U.S. hospital discharges, to study outcomes and predictors of mortality in hospitalized patients with TLS. The NIS was queried for patients with a discharge diagnosis of TLS (ICD-9 code 277.88) from 2010-2013. Baseline characteristics and outcomes were analyzed. A multivariable logistic regression analysis was performed to identify predictors of mortality...

Patients with relapsed/refractory B-cell malignancies such as non-Hodgkin lymphoma (B-NHL) or acute lymphoblastic leukemia (B-ALL) have a poor prognosis. Despite measurable clinical activity with new targeted therapies, many patients do not achieve a complete or durable response suggesting an opportunity to improve upon existing therapies. Here we describe SGN-CD19B, a pyrrolobenzodiazepine (PBD)-based anti-CD19 antibody drug conjugate (ADC) being investigated for treatment of B-cell malignancies, which has improved potency compared to other ADCs...

BACKGROUND: Efficacy and the risk of severe late effects have to be well-balanced in treatment of Hodgkin lymphoma (HL). Late adverse effects include secondary malignancies which often have a poor prognosis. To synthesise evidence on the risk of secondary malignancies after current treatment approaches comprising chemotherapy and/or radiotherapy, we performed a meta-analysis based on individual patient data (IPD) from patients treated for newly diagnosed HL. OBJECTIVES: We investigated several questions concerning possible changes in the risk of secondary malignancies when modifying chemotherapy or radiotherapy (omission of radiotherapy, reduction of the radiation field, reduction of the radiation dose, use of fewer chemotherapy cycles, intensification of chemotherapy)...

Type I interferons (IFNs) such as IFN-α, IFN-β, IFN-ε, IFN-κ, and IFN-ω represent cytokines, which are deeply involved in the regulation and activation of innate and adaptive immune responses. They possess strong antiviral, antiproliferative, and immunomodulatory activities allowing their use in the therapy of different viral diseases, neoplasms, and immune-mediated disorders, respectively. Initially, treatment strategies were based on nonspecific inducers of type I IFNs, which were soon replaced by different recombinant proteins...

Canine lymphoma is a heterogeneous disease with many different subtypes. Lymphoma of T cell type in particular is variable in outcome, and includes subtypes with non-progressive, slowly- and rapidly-progressive disease course. Association of immunotype with disease course is incompletely defined. Here, results of flow cytometric immunotyping of 127 canine T cell lymphomas were analyzed in relation to survival and progression free interval. Samples originated from 101 multicentric, 8 mediastinal, 6 cutaneous, 5 hepatosplenic, 5 gastrointestinal and 2 other anatomic subtypes of T cell lymphoma...

Hairy B-cell lymphoproliferative disorder (HBLD) is one of chronic polyclonal B-cell lymphocytosis. We report a 47-year-old female Japanese patient diagnosed as having HBLD based on lymphocytosis with hairy cell appearance and characteristic phenotypes including CD11c+ and without B-cell monoclonality. She was a non-smoker and possessed HLA-DR4. She has been closely followed up without treatment and lymphoma development for over five years. Although this disease is quite rare and has been reported, to our knowledge, in only 13 Japanese cases, an accurate diagnosis, particularly differential diagnosis from persistent polyclonal B-cell lymphocytosis or hairy cell leukemia-Japanese variant is essential for the prevention of unnecessary treatments...

Associations between immunoglobulin (IG) receptors with distinctive immunogenetic features and particular gene mutations is a recurring theme in mature B cell lymphomas. Relevant observations have been made in chronic lymphocytic leukemia (CLL), where gene mutations are distributed asymmetrically in cases bearing or not somatic hypermutations within the clonotypic immunoglobulin heavy chain variable region (IGHV) genes (e.g. TP53 mutations predominate in IG-unmutated CLL, whereas the opposite is seen for MYD88 mutations, enriched in IG-mutated CLL) and in subsets of cases with stereotyped IG (enrichment for SF3B1 mutations in CLL subset #2)...

The human T-lymphotropic virus type-1 (HTLV-1) is the causative agent of adult T cell leukemia/lymphoma (ATL) and HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). CD4(+)T cells are the main target of HTLV-1, but other cell types are known to be infected, including immature lymphocytes. Developing T cells undergo differentiation in the thymus, through migration and interaction with the thymic microenvironment, in particular with thymic epithelial cells (TEC) the major component of this three dimensional meshwork of non-lymphoid cells...
