BACKGROUND AND AIM: Chronic HCV infection is associated with several extrahepatic manifestations (EHMs). Data on the effect of sustained virological response (SVR) on the risk of EHMs are limited. METHODS: We conducted a retrospective cohort study using data of patients from the US Veterans Affairs HCV Clinical Case Registry who had a positive HCV RNA test (10/1999-08/2009). Patients receiving interferon-based antiviral therapy (AVT) were identified. SVR was defined as negative HCV RNA at least 12 weeks after end of AVT...

Non-Hodgkin's lymphoma (NHL) constitutes a collection of lymphoproliferative disorders with diverse biologic, histologic, and clinical features. With a better understanding of the molecular pathogenesis, recently there have been major advances in the treatment of NHLs including addition of novel monoclonal antibodies, targeted therapies, and immune activators to the therapy armamentarium. Despite these remarkable developments, autologous hematopoietic cell transplantation (auto-HCT) remains not only a standard-of-care curative option for aggressive NHL but also an important therapeutic option for indolent NHL...

OBJECTIVE/BACKGROUND: Primary central nervous system lymphoma (PCNSL) is associated with worst prognosis compared with other aggressive non-Hodgkin's lymphomas. However, recent trials have demonstrated that long-term progression-free survival can be achieved by immunochemotherapy. Our goal is to present our experience in aggressive PCNSL in this study. METHODS: We retrospectively evaluated the clinical features and management of 13 PCNSL patients who were diagnosed and treated between 2006 and 2015...

Composite lymphoma is a rare tumor composed of two or more distinct lymphomas in the same topographic site or tissue. Several combinations of B-cell non-Hodgkin lymphoma (NHL), T-cell NHL, and Hodgkin lymphoma can occur with different prognoses and treatments. The coexistence of a B-cell NHL and a T-cell NHL is unusual. The exact etiology of composite lymphoma is unknown; however, few mechanisms have been proposed to explain its pathogenesis. The chemotherapeutic protocols are heterogeneous but are essentially targeted against the high-grade component...

Globally, peripheral T-cell lymphomas (PTCLs) constitute about 12% of all non-Hodgkin lymphomas, of which the unspecified category is the most common subtype (30%). Mostly, the unspecified category shows a diffuse pattern of involvement in the lymph nodes. However, rarely, they may show a follicular/nodular pattern mimicking a follicular lymphoma. We report a case of a follicular variant of PTCL, not otherwise specified. This case displayed a striking nodular/follicular pattern with an admixture of small (centrocyte-like) and large (centroblast-like) cells, thus mimicking a follicular lymphoma...

BACKGROUND: Peripheral T-cell lymphomas (PTCLs) are non-Hodgkin's lymphomas (NHLs) with considerable variation in incidence across the world. They show a wide variety of clinicopathological features and generally associated with poor clinical outcome. Lymphoma data from different geographic regions will definitely aid in routine clinical practice and research work. PTCLs are reported with a higher frequency in Asia as compared to Western countries. OBJECTIVE: The objective of this study was to analyze the frequency and distribution of PTCLs diagnosed in a tertiary care cancer center in Kerala...

Ibrutinib is a Bruton's tyrosine kinase (BTK) inhibitor finding increasingly widespread use in non-Hodgkin lymphoma. Evidence of an increased risk of atrial fibrillation (AF) emerged in Phase III studies with a median incidence of approximately 6%. The mechanism remains unknown, but inhibition of a cardioprotective pathway has been proposed. Ibrutinib induces a platelet function defect, increasing the bleeding risk of anticoagulation for AF stroke prophylaxis. Multiple potential drug interactions are an added complication...

REVIEW
Lu Zhang, Michele Ghielmini, Bruce D Cheson, Chaitra Ujjani
Follicular lymphoma (FL) is the most prevalent indolent non-Hodgkin lymphoma. Most patients present with advanced disease and are incurable with current therapy. The approval of rituximab has revolutionized the treatment of follicular lymphoma when administered in the induction setting for high-tumor burden disease, but the use of rituximab as a maintenance therapy (MR) continues to be a point of controversy. In this article, we review the main data and arguments in favor and against MR in FL. In summary, most studies have demonstrated a significant benefit in progression-free or event-free survival in this notoriously recurrent disease; however, long-term outcomes could not consistently demonstrate to be improved with this intervention...

Anaplastic large cell lymphoma (ALCL) is a CD30+ T-cell non-Hodgkin lymphoma with two main clinical presentations: primary cutaneous (pcALCL) and systemic (sALCL). While rare cases of myxoid sALCL have been reported, there are no previous cases of myxoid pcALCL reported. We present two unusual cases of pcALCL showing prominent collections of dermal mucin closely intermingling with the anaplastic lymphocytes. Patient 1 was a 30-year-old woman who presented with ulcerated nodules on her neck, abdomen, chest, and shoulders...

The occurrence of extranodal primary B cell non-Hodgkin's lymphoma is rare. Total hip replacement is one of the most common orthopaedic procedures performed. There has been an increased incidence of primary lymphomas involving periprosthetic sites. Chronic inflammation due to metal debris arising from the prosthetic implants has been evidenced as one of the causes for the development of soft tissue lymphomas albeit rarely. We describe a case report of a 77-year-old patient who had underwent a cemented total hip replacement in the past who further developed large B cell primary non-Hodgkin's lymphoma...

Neck pain is a common reason for seeking medical attention. It affects at least 15% of the labor force and up to 40% of individuals whose occupation is hazardous. On the other hand, primary bone lymphoma is a very rare disease (less than 1% of all malignant bone tumors), and the relationship between the 2 has rarely been mentioned. We report the case of a patient who had a 1-month history of neck pain. The main symptom was pain on palpation of C2-C6 cervical spinous processes and contracture of the trapezius muscle that did not cease with conventional treatment...

BACKGROUND: Previous studies have provided limited support to the association between tobacco smoking and lymphomas with weak evidence of a dose-response relationship. METHODS: We investigated the relationship between tobacco smoking and risk of non-Hodgkin lymphomas (NHL) and Hodgkin lymphomas (HL) through logistic regression spline models. Data were derived from an Italian hospital-based case-control study (1999-2014), which enrolled 571 NHLs, 188 HLs, and 1004 cancer-free controls...

Persistent human papillomavirus (HPV) infection may promote carcinogenesis by hyperactivation of the immune system. We, therefore, explored the associations between HPV infection and risk of Hodgkin and non-Hodgkin lymphoma in a nationwide cohort study using conization as a surrogate marker. We identified all Danish women who underwent conization between 1978 and 2011. We computed standardized incidence ratios and 95% confidence intervals for Hodgkin and non-Hodgkin lymphoma based on national cancer incidence rates...

Background: Human immunodefieciency virus (HIV)-infected persons are living longer in the era of effective HIV treatment, resulting in an increasing cancer burden in this population. The combined effects of HIV and cancer on mortality are incompletely understood.Methods: We examined whether individuals with both HIV and cancer have excess mortality using data from the HIV/AIDS Cancer Match Study and the National Center for Health Statistics (1996-2010). We compared age, sex, and race-stratified mortality between people with and without HIV or one of the following cancers: lung, breast, prostate, colorectum, anus, Hodgkin lymphoma, or non-Hodgkin lymphoma...

Non-Hodgkin lymphoma is a heterogeneous group of lympho-proliferative disorders. We performed a meta-analysis to summarize the available evidence from case-control studies and cohort study on the inconsistent association between occupational sun exposure and the risk of non-Hodgkin lymphoma. We searched PubMed, ISI web of science, the Cochrane Library, EMBASE and reference lists for relevant articles. Study specific odds ratios or relative risk and 95% confidence intervals were pooled by using fixed-effects or random-effects models...

Double Hit (DH) or Double Expressor (DE) diffuse large B-cell lymphoma (DLBCL) are aggressive Non-Hodgkin's Lymphomas (NHLs) with translocations and/or over-expressions of MYC and BCL-2, that are difficult to treat. Aurora kinase (AK) inhibition with alisertib in DH/DE-DLBCL induces cell death in ~30%, while ~70% are aneuploid and senescent cells (AASCs), a mitotic escape mechanism contributing to drug resistance. These AASCs elaborated a high metabolic rate by increased AKT/mTOR and ERK/MAPK activity via BTK signaling through the chronic active B-cell receptor (BCR) pathway...
