BACKGROUND: RV1001 is a novel, potent, and selective PI3Kδ inhibitor. The purpose of this study was to evaluate the safety and efficacy of RV1001 in canine Non-Hodgkin lymphoma (NHL). METHODS AND RESULTS: Inhibition of endogenous pAKT by RV1001 in primary canine NHL cells was determined by Western blotting. A phase I study of RV1001 was performed in 21 dogs with naïve and drug resistant T and B-cell NHL to assess safety, pharmacokinetic profile, and response to therapy...

In aggressive lymphomas, discrepancies in survival reported from experimental and observational studies may reflect selective non-enrolment of high-risk patients in trials. We examined the association between time from diagnosis to chemotherapy and overall survival in diffuse large B-cell (DLBCL), Burkitt (BL), mantle cell (MCL) and peripheral T-cell lymphoma (PTCL), using National Cancer Data Base records of 130 549 patients treated in 2004-2014. Across the histologies, patients who started chemotherapy within 7 days of diagnosis had more often high International Prognostic Index (IPI) or advanced-stage disease...

No systematic reviews are available on data from humans on cancer risk from exposure to permethrin, a widely used insecticide for which some animal studies have reported positive findings based on mechanisms that may not be relevant to humans. We identified potentially relevant articles through a search of electronic databases which included all studies of pesticide exposure and human cancer. A total of 18 articles were selected, including six identified from the list of references of other articles. Most articles were based on analyzes of the Agriculture Health Study (AHS); they provided no evidence of an increased risk of cancers of colon, rectum, pancreas, lung, melanoma, female breast, prostate, urinary bladder, as well as non-Hodgkin lymphoma (including its main subtypes), and leukemia...

Primary mediastinal B-cell lymphoma (PMBCL) is a subtype of non-Hodgkin's lymphoma, which occurs rarely in pregnancy. We present a case of a pregnant 22-year-old female who presented with syncope and dyspnea. Computed tomography (CT) chest showed an anterior mediastinal mass, and its biopsy showed PMBCL. Since she was in her second trimester, we decided to treat her with rituximab-cyclophosphamide, doxorubicin, vincristine, prednisone (R-CHOP). Our case emphasizes the safety of chemotherapy in the second and third trimesters, with good maternal and fetal outcomes...

Objective: With the advent of screening tests, it was hypothesised that milder cases of coeliac disease coming to diagnosis might have reduced risk of mortality. An earlier publication did not support this view. We have re-examined this issue employing a larger number of patients followed for a further 8 years. Design: Patients with coeliac disease from Southern Derbyshire, UK, were followed prospectively from 1978 to 2014 and included those diagnosed by biopsy and serology...

The application of allogeneic hematopoietic cell transplantation (allo-HCT) in non-Hodgkin lymphoma (NHL) patients ≥65 years in the United States is limited by lack of Medicare coverage for this indication. Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we report allo-HCT outcomes of NHL patients aged ≥65 years (older cohort; n = 446) compared with a cohort of younger NHL patients aged 55-64 years (n = 1183). We identified 1629 NHL patients undergoing a first reduced-intensity conditioning (RIC) or nonmyeloablative conditioning allo-HCT from 2008 to 2015 in the United States...

Epstein-Barr virus (EBV) causes various diseases in the elderly including B-cell lymphoma such as Hodgkin's lymphoma (HL) and diffuse large B-cell lymphoma (DLBCL). Here, we show that EBV acts in trans on non-infected macrophages in the tumor through exosome secretion and augments the development of lymphomas. In a humanized mouse model, the different formation of lymphoproliferative disease (LPD) between two EBV strains (Akata and B95-8) was evident. Furthermore, injection of Akata derived exosomes affected LPD severity possibly through the regulation of macrophage phenotype in vivo...

INTRODUCTION: Diagnosing lymphoma continues to prove challenging in the clinical practice. Composite lymphoma (CL) is defined by the coexistence of different lymphoma subtypes in the same anatomical location. This condition has seldom been witnessed in the gastrointestinal (GI) tract. We weren't able to find previous cases in the literature about small bowel CL with follicular lymphoma (FL) and classical Hodgkin lymphoma (CHL). Surgery is the treatment of choice to obtain accurate histology, to manage and prevent acute complications...

Peripheral T-cell lymphoma (PTCL) is a rare, aggressive, heterogeneous, Non-Hodgkin's lymphoma with poor prognosis and inadequate response to current therapies. Recent sequencing studies indicate a prevalence of activating mutations in the JAK/STAT signaling pathway. Oncogenic mutations in STAT5B, observed in approximately one third of cases of multiple different PTCL subtypes, correlate with inferior patient outcomes. Therefore, interest in the development of therapeutic strategies for targeting STAT5 in PTCL is warranted...

Upconversion nanoparticles are a new type of fluorescent marker in biomedical imaging that can convert a longer wavelength (such as near-infrared fluorescence) into a shorter wavelength (such as visible light). Mantle cell lymphoma, which is derived from B-cell lymphoma, is a subtype of non-Hodgkin's lymphoma, and the immune phenotype is a mature B-cell phenotype (CD20+, CD5+). To develop the use of nanomaterials as specific markers for the medical imaging of mantle cell lymphoma, we modified the surface of UCNPs by oxidation so that the CD20 or CD5 antibody could covalently attach to the upconversion nanoparticles to form antibody-UCNP conjugates...

After years of setback, cancer immunotherapy has begun to yield clinical dividends, which are changing the treatment landscape and offering cancer patients the potential for long-term survival, reduced treatment-related toxicity and improved quality-of-life. Using the immune system to treat cancer is known as 'Immuno-oncology' (IO) and agents are sub-classified by their ability to enhance anti-tumor response or to direct the immune system to attack cancer cells via tumor-associated antigens. Areas covered: Clinical trials have demonstrated the effectiveness of several IO agents in many disease sites such as early and advanced stage melanoma, advanced non-small cell lung cancer, bladder, head and neck, gastric, kidney as well as Hodgkin's lymphoma...

OBJECTIVE: Older patients with cancer suffer from chemotherapy-related toxicities more frequently than younger patients. As novel agents are being used more commonly in chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL), toxicities of these agents in older patients have not been well studied. Further, impact of these toxicities on outcomes in the elderly is unknown. This study aimed to answer both questions. PATIENTS AND METHODS: We reviewed 14 Alliance for Clinical Trials in Oncology trials that enrolled CLL and/or NHL patients between 2004-2014...

BACKGROUND: Acquired C1-esterase inhibitor (C1-INH) deficiency angioedema (C1-INH-AAE) is a form of bradykinin-mediated angioedema. This rare disorder is due to acquired consumption of C1-INH, hyperactivation of the classic pathway of human complement, and potentially fatal recurrent angioedema symptoms. Clinical symptoms of C1-INH-AAE are very similar to those of hereditary angioedema (HAE) but usually appear after the fourth decade of life and induce abdominal pain less frequently. Laboratory tests are essential in establishing the diagnosis with low levels or abnormal structure and function of C1-INH...

BACKGROUND: Angioimmunoblastic T cell lymphoma is a rare malignancy, accounting for only 2% of all non-Hodgkin lymphomas, first described in the 1970s and subsequently accepted as a distinct entity in the current World Health Organization classification. Due to the paucity of this disease, there is still no identifiable etiology, no consistent risk factors, and the pathogenesis remains unclear. CASE PRESENTATION: An 83-year-old Caucasian man presented to an emergency department with palpitations and was found to have atrial fibrillation...

Carcinoid tumorlets are peribronchiolar proliferations of neuroendocrine cells often associated with lung scars. Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a non-Hodgkin's lymphoma that frequently involves the gastrointestinal tract but less commonly is described in the lung. Simultaneous occurrence of neuroendocrine neoplasms and MALT lymphoma is extraordinarily rare and has predominately been reported in the gastrointestinal tract. In this article, we describe the case of a 73-year-old female with coexisting pulmonary MALT lymphoma and carcinoid tumorlets of the right middle lobe...

Vitreoretinal lymphoma, which most commonly is diffuse large B cell non-Hodgkin in type, is a rare cancer with high morbidity and high mortality. Making a tissue diagnosis of vitreoretinal lymphoma is a major challenge for clinicians due to biological and technical factors. Yet, the delay in start of treatment may have vision- and life- threatening consequences, and there is considerable interest in the application of molecular assays to improve the accuracy of the diagnostic process: detection of a clonal immunoglobulin heavy chain rearrangements in lymphoma cells by polymerase chain reaction; measurement of vitreous or aqueous interleukin-10 protein levels in ocular fluids; and identification of mutations in the myeloid differentiation primary response gene 88 in tumour cells...
