Primary central nervous system lymphoma (PCNSL) is an extranodal non-Hodgkin lymphoma limited to the brain, spinal cord, leptomeninges, and eyes. The majority of patients are immunocompetent, with a median age of 65 years at diagnosis. Historically, whole-brain radiation therapy (WBRT) was the first and sole treatment for PCNSL. Today, due to the recognized neurotoxicity of WBRT, this modality is usually avoided in the treatment. Most chemotherapy regimens are based on high-dose methotrexate plus the anti-CD20 monoclonal antibody rituximab, leading to high response rates, but 5-year survival is still poor at approximately 30% compared with other extranodal lymphomas...

INTRODUCTION: Secondary pancreatic tumors are uncommon and account for 2-5% of pancreatic cancer. Tumors characterized most commonly with pancreatic involvement are lymphoma, renal cell and lung carcinomas. PRESENTATION OF CASE: A 76-year-old female patient with obstructive jaundice as the primary symptom and inguinal lymphadenopathy is presented. Imaging revealed a bulky solitary solid pancreatic head mass along with paraaortic and mesenteric lymphadenopathy. The absence of a previous history of malignancy and the presence of a dominant pancreatic mass along with distal lymphadenopathy confined differential diagnosis to advanced secondary pancreatic lymphoma, which is the most common secondary pancreatic tumor, and locally advanced/metastatic pancreatic adenocarcinoma...

Primary bone lymphoma is a rare disease, accounting for less than 5% of all extranodal lymphoma. Although the femur is cited as being the most common site, primary bone lymphoma is rare, accounting for less than 1% of all non-Hodgkin's lymphoma. Herein we present a case of diffuse B-cell-type malignant lymphoma manifested as a large soft-tissue mass of the leg, via metastasis of primary non-Hodgkin's lymphoma of the femur, which went untreated. We highlight the advantages of various imaging modalities used throughout the process of diagnosis and treatment because accurate and early diagnosis are essential...

Non-Hodgkin lymphoma of the bone is rare and typically causes an extensive bone lesion. The present study describes a case of diffuse large B-cell primary non-Hodgkin lymphoma of the bone, which occurred in the right femur, and was initially treated with surgery and chemotherapy. Following a 7-year period of complete remission, a new, similar lesion was identified in the left femur. With both lesions, there was no accompanying destruction of any other bones or organ involvement. Metastasis of PLB to the contralateral side is extremely rare and, to the best of our knowledge, this is the first report of this particular presentation in China or worldwide...

BACKGROUND: The first step in the production of chimeric antigen receptor T cells is the collection of autologous T cells using apheresis technology. The procedure is technically challenging, because patients often have low leukocyte counts and are heavily pretreated with multiple lines of chemotherapy, marrow transplantation, and/or radiotherapy. Here, we report our experience of collecting T lymphocytes for chimeric antigen receptor T-cell manufacturing in pediatric and young adult patients with leukemia, non-Hodgkin lymphoma, or neuroblastoma...

Previous studies have focused on the relationship between hepatitis B virus (HBV) infection and non-Hodgkin lymphoma (NHL). However, the results remain inconsistent and somehow conflicting in different sub-groups. The aim of this study was to combine the findings of independent studies to comprehensively assess the association between HBV and NHL using a meta-analysis. Relevant studies were identified through structured keyword searches in PubMed, EMBASE and the China National Knowledge Infrastructure (CNKI) database and 58 studies with a total of 53,714 NHL cases and 1,778,591 controls were finally included...

Background: The incidence and biology of non-Hodgkin lymphoma (NHL) vary according to age. Some data suggest that the impact of age in pediatric and adolescent NHL patients depends on the histological subtype. Objectives: We aimed to analyze the impact of age at diagnosis on clinical characteristics and treatment-related toxicity in children and adolescents with NHL. Methods: Retrospective review of medical records of children and adolescents diagnosed with NHL at the Hospital for Sick Children, Toronto, between January 1995 and December 2008...

OBJECTIVE: To study the difference in expression of TOPK/PBK in lymph nodes between children with malignant lymphoma and those with reactive lymphoid hyperplasia. METHODS: Eighty children with malignant lymphoma and twenty children with reactive lymphoid hyperplasia were enrolled as subjects. Immunohistochemistry was used to determine the expression of TOPK/PBK in all the subjects. The expression of TOPK/PBK was compared between the two groups. RESULTS: The TOPK/PBK-positivity rate was significantly higher in children with malignant lymphoma than in those with reactive lymphoid hyperplasia (P<0...

Primary hepatic peripheral T-cell lymphoma (H-PTCL) is one of the rarest forms of non-Hodgkin lymphoma. We report a patient who presented with worsening jaundice, abdominal pain, and vomiting. Laboratory values were significant for elevated total bilirubin, alkaline phosphatase, and liver aminotransferases. Following a liver biopsy, histopathology revealed several large dense clusters of atypical T-lymphocytes which were CD2+, CD3+, CD5+, CD7-, CD4+, CD8-, CD56-, CD57-, CD30+ by immunohistochemistry. The proliferation index was approximately 70% by labeling for ki67/mib1...

Non-Hodgkin lymphomas (NHL) are a group of cancers with highly heterogeneous biology and clinical features. Statins are increasingly prescribed to prevent cardiovascular diseases. Early evidence shows a preventive effect of statins for some cancers, but their effect on NHL risk is unclear. We conducted a population-based nested case-control study involving 5,541 NHL cases and 27,315 controls matched for gender, age, place of residence, and length of period of available prescription drug data. We assessed the use of statins prior to diagnosis (excluding the 12 months prior to the index date)...

Mantle cell lymphoma (MCL) is a rare but often aggressive B-cell non-Hodgkin lymphoma (NHL). Initial therapy can achieve high response rates but invariably patients relapse and die from their disease. Incorporating a maintenance phase into the treatment strategy may prolong remission duration and ultimately prolong survival. Areas covered: The current literature incorporating a maintenance phase into treatment strategies for newly diagnosed and pre-treated MCL patients has been summarized. A literature search was performed using search terms "mantle cell lymphoma", "indolent NHL", "maintenance", "interferon", "rituximab", "lenalidomide", "bortezomib" and "ibrutinib"...

The main cause of death in mantle cell lymphoma (MCL) patients is relapse due to undetermined minimal residual disease (MRD) and therefore monitoring MRD is crucial for making the best treatment decisions. The gold standard method for MRD analysis is the quantitative polymerase chain reaction. The most commonly used molecular markers for measuring MRD in MCL are: t(11;14)(q13;p32) translocation or CCND1 expression and IGH rearrangement. Such markers can, however, be found in other B cell non-Hodgkin lymphomas...

Primary (localized) non-Hodgkin lymphoma (NHL) of the ovary is extremely rare; only a few cases have been reported in the literature. We report two cases of primary ovarian lymphoma (POL), one involving bilateral ovaries in a 15-year-old girl and other involving one ovary in a 5-year-old girl. This report describes detailed clinical, histopathological, and imaging findings, along with the review of literature of primary diffuse large B-cell lymphoma (DLBCL) arising from an ovary. In addition, we describe findings of targeted capture panel sequencing on both tumors and identify the major genetic mutations that are recurrently mutated in pan-cancers...

The clinical outcome of T-cell non-Hodgkin lymphoma (NHL) is poor and innovative treatments are needed. Tenascin-C is a large extracellular glycoprotein not expressed under physiological conditions, but overexpressed in cancer. Aim of the study was to evaluate tenascin-C expression within pathologic tissue of T-cell NHL and determine its clinical significance. We used an immunohistochemistry approach using the anti-tenascin-C monoclonal antibody Tenatumomab in 75 systemic T-cell NHL (including 72 mature and 3 precursor T-cell NHL), and 25 primary cutaneous T-cell NHL...

Constitutive signaling of PI3K/Akt/mTOR plays a prominent role in malignant transformation and progression of B-cell non-Hodgkin lymphomas (B-NHL) underscoring the need for PI3K targeted therapies. The pan-class I PI3-kinase inhibitor BKM120 has shown preclinical activity in distinct malignancies and is currently tested in clinical trials. Intratumor heterogeneity is an intrinsic property of cancers that contributes to drug resistance and tumor recurrence. Here, we demonstrate that inhibition of PI3-kinases by BKM120 attenuates growth and survival of B-NHL cell lines by inducing mitotic arrest with subsequent induction of intrinsic apoptosis...

Achalasia secondary to underlying neoplasm is a rare entity. Early recognition of secondary achalasia is important as its treatment involves management of underlying malignancy, while treatment of primary achalasia mainly involves lowering the lower oesophageal sphincter pressure with pneumatic dilatation or Heller's myotomy. We discuss an interesting case of achalasia secondary to non-Hodgkin's lymphoma.
