Multiple Myeloma (MM), a clonal malignancy of antibody-producing plasma cells, is the second most common hematologic malignancy and results in significant patient morbidity and mortality. The high degree of immune dysregulation in MM, including T cell imbalances and up-regulation of immunosuppressive checkpoint proteins and myeloid derived suppressor cells, allows this malignancy to escape from host immune control. Despite advances in the therapeutic landscape of MM over the last decade, including the introduction of immunomodulatory drugs, the prognosis for this disease is poor, with less than 50% of patients surviving 5 years...

Purpose: Although hepatitis B surface antigen (HBsAg)-negative, hepatitis B core antibody (anti-HBc)-negative patients are not considered to be at risk for hepatitis B virus (HBV)-related hepatitis, the actual risk remains to be elucidated. This study aimed to evaluate the risk of HBV-related hepatitis in HBsAg-negative, anti-HBc-negative patients receiving autologous stem cell transplantation (ASCT) for multiple myeloma (MM) or malignant lymphoma. Materials and Methods: We retrospectively reviewed data from 271 HBsAg-negative patients (161 anti-HBc-negative and 110 anti-HBc-positive at the time of ASCT) who received ASCT for MM or lymphoma...

We retrospectively analyzed a large study to investigate the association of hepatitis B virus (HBV) with aggressive B cell non-Hodgkin's lymphoma (aggressive B-NHL) in China, where HBV is endemic. HBV was present in 39 aggressive B-NHL patients (10.46%), 13 indolent B-NHL patients (5.09%), 12 multiple myeloma (MM) patients (3.67%), and 5 solitary plasmacytoma (SP) patients (6.67%). HBV infection was significantly associated with increased risks for aggressive B-NHL (P < 0.01). HBV seems to have a very important role in the pathogenesis of aggressive B-NHL in China...

A higher risk for a variety of cancers is among the major complications of post-transplant immunosuppression. In this part of a continuing series on cancers post-transplant, this review focuses on the hematologic cancers after solid organ transplant. Post-transplant lymphoproliferative disorders (PTLDs), which comprise the great majority of hematologic cancers, represent a spectrum of conditions that include, but are not limited to, the Hodgkin and non-Hodgkin lymphomas. The oncogenic Epstein-Barr virus is a key pathogenic driver in many PTLD cases, through known and unknown mechanisms...

SLAMF7 is under intense investigation as a target for immunotherapy in multiple myeloma. Here, we redirected the specificity of T-cells to SLAMF7 through expression of a chimeric antigen receptor (CAR) derived from the huLuc63 antibody (Elotuzumab), and demonstrate that SLAMF7-CAR T-cells prepared from patients and healthy donors confer potent antimyeloma reactivity. We confirmed uniform, high-level expression of SLAMF7 on malignant plasma cells in previously untreated and in relapsed/refractory (R/R) myeloma patients who had received prior treatment with proteasome-inhibitors and immunomodulatory agents (IMiDs)...

Subsets of mature B cell neoplasms are linked to infection with intracellular pathogens such as Epstein-Barr virus (EBV), hepatitis C virus (HCV), or Helicobacter pylori. However, the association between infection and the immunoglobulin-secreting (Ig-secreting) B proliferative disorders remains largely unresolved. We investigated whether the monoclonal IgG (mc IgG) produced by patients diagnosed with monoclonal gammopathy of undetermined significance (MGUS) or multiple myeloma (MM) targets infectious pathogens...

Previously called Crow-Fukase syndrome, POEMS syndrome is characterized by poly-neuropathy, osteo-sclerotic myeloma, organomegaly, endocrinopathy, monoclonal plasma cell disorder, and skin changes. Extremely elevated levels of serum vascular endothelial growth factor (VEGF) are characteristic of the syndrome. Chronic hepatitis B (HBV) and C (HCV) infections can also be present in POEMS. The pathogenesis of the syndrome is not well understood. The link between chronic alcohol consumption and this malignant condition has not been reported until now...

Oncolytic viruses (OVs) are emerging as powerful anti-cancer agents and are currently being tested for their safety and efficacy in patients. Reovirus (Reolysin), a naturally occurring non-pathogenic, double-stranded RNA virus, has natural oncolytic activity and is being tested in phase I-III clinical trials in a variety of tumor types. With its recent US Food and Drug Administration (FDA) orphan drug designation for several tumor types, Reolysin is a potential therapeutic agent for various cancers, including head and neck squamous cell carcinomas (HNSCCs), which have a 5-year survival of ∼55%...

Multiple myeloma is a malignancy of plasma cells of the bone marrow. Although the prognosis is variable, no curative therapy has been defined. Vaccinia virus infects cancer cells and kills such cells in a variety of ways. These include direct infection, triggering of immunomediated cell death, and vascular collapse. The potential of the vaccinia virus as an anti-tumor therapy has attracted the attention of oncologists. Interestingly, our preliminary experiments revealed that myeloma cells were particularly susceptible to vaccinia virus...

Background and Aim: The vast majority of the 2.7 million individuals in the United States who are currently infected with hepatitis C virus (HCV) were born between 1945 and 1965. The median age of these patients in this particular generation at the time of this writing was 55 years. In the general population, older age is a risk factor for multiple myeloma (MM) and other monogammopathies. As the baby boomer population ages, HCV providers are increasingly likely to encounter HCV-infected patients with a monoclonal gammopathy...

Hepatitis C virus (HCV) infection is a leading cause of chronic liver damage and is associated with other diseases. Some studies reported that patients with HCV have a significantly increased risk of multiple myeloma while others do not report an association.We aimed to clarify the association between HCV and multiple myeloma and analyze the factors that affect the controversial conclusions through a meta-analysis. We conducted a systematic literature search of HCV and myeloma in the databases of PubMed/Medline, Cochrane Library, EMBASE, Wanfang, and China National Knowledge Infrastructure (CNKI) from inception to Sep 2016...

BACKGROUND: The effects of pediatric solid organ transplantation on cancer risk may differ from those observed in adult recipients. We described cancers in pediatric recipients and compared incidence to the general population. METHODS: The US transplant registry was linked to 16 cancer registries to identify cancer diagnoses among recipients <18 years old at transplant. Standardized incidence ratios (SIRs) were estimated by dividing observed cancer counts among recipients by expected counts based on the general population rates...

Non-Hodgkin lymphoma (NHL) and leukemia are among the most common cancers worldwide. While the treatment of NHL/leukemia of B-cell origin has much progressed with the introduction of targeted therapies, few treatment standards have been established for T-NHL/leukemia. As presentation in both B- and T-NHL/leukemia patients is often aggressive and as prognosis for relapsed disease is especially dismal, this cancer entity poses major challenges and requires innovative therapeutic approaches. In clinical trials, oncolytic viruses (OVs) have been used against refractory multiple myeloma (MM)...

Hepatitis C virus (HCV) is a blood-borne pathogen which has chronically infected people worldwide. Therefore, it is of utmost importance to design prophylactic and therapeutic vaccine in order to control HCV infection. To date, several researchers have attempted to improve the efficiency of HCV vaccine by using different adjuvants. However, a few studies have focused on the synthetic immunomodulatory drugs as adjuvants for HCV vaccine. Recently, researchers have shown that lenalidomide, which is used to treat the patients with multiple myeloma, is capable of improving the immune system factors...

Micro-organism resistance is an important challenge in modern medicine due to the global uncontrolled use of antibiotics. Natural and synthetic antimicrobial peptides (AMPs) symbolize a new family of antibiotics, which have stimulated research and clinical interest as new therapeutic options for infections. They represent one of the most promising antimicrobial substances, due to their broad spectrum of biological activity, against bacteria, fungi, protozoa, viruses, yeast and even tumour cells. Besides, being antimicrobial, AMPs have been shown to bind and neutralize bacterial endotoxins, as well as possess immunomodulatory, anti-inflammatory, wound-healing, angiogenic and antitumour properties...
