Patients with HIV are at increased risk for developing B-cell lymphomas likely due in part to chronic antigen stimulation leading to clonal immunoglobulin (Ig) gene rearrangements. Next-generation sequencing (NGS)-based identification of circulating Ig clonotypes has not been well-characterized in HIV-related lymphomas. The AIDS Malignancies Consortium (AMC) enrolled 51 untreated patients with HIV-related B-cell lymphomas and analyzed paired tumor/plasma specimens for Ig clonotypes using an NGS approach (AMC064, NCT00981097)...

The emergence of HIV/AIDS more than three decades ago led to an increased incidence of diseases caused by HHV8 co-infection, particularly Kaposi sarcoma, primary effusion lymphoma, and multicentric Castleman disease. Over time, the development of highly effective AIDS therapies has resulted in a decreased incidence of HHV8-associated entities, which are now more commonly found in patients with undiagnosed and/or untreated AIDS. Due to their rarity, some of these diseases may be difficult to recognize without appropriate clinical information...

AIDS-related cancer diseases are malignancies with low incidence on healthy people that affect mostly subjects already immunocompromised. The connection between HIV/AIDS and these cancers has not been established yet, but a weakened immune system is certainly the main cause. We envisaged the possibility to screen a small library of compounds synthesized in our laboratory against opportunistic tumors mainly due to HIV infection like Burkitt's Lymphoma. From cellular assays and gene expression analysis we identified two promising compounds...

Endemic Burkitt lymphoma (eBL) is an aggressive B cell lymphoma and is associated with Epstein-Barr virus (EBV) and Plasmodium falciparum malaria co-infections. Central to BL oncogenesis is the over-expression of the MYC proto-oncogene which is caused by a translocation of an Ig enhancer in approximation to the myc gene. While whole genome/transcriptome sequencing methods have been used to define driver mutations and transcriptional dysregulation, microRNA (miRNA) dysregulation and differential expression has yet to be fully characterized...

Lymphoma is fourth most frequent malignancy diagnosed prenatally (~1:6000 cases), with Hodgkin's Lymphoma (HL) forming the major chunk. However, in recent times, there has been an increase in occurrence of Non-Hodgkin's Lymphoma (NHL) due to late child bearing age and high incidence of AIDS-related NHL in developing countries. Managing NHL in pregnancy involves intricate medical, ethical and psychological issues. Diagnostic and treatment delays may influence the prognosis for indolent cases. Seen the complexity of the management decisions associated with NHL, interdisciplinary and individualized approach becomes imperative for each woman...

Large epidemiological studies have shown a consistent increased risk for developing lymphoma in the setting of autoimmune disorders (AID). It is known that this link appears to be stronger for some AID and certain non-Hodgkin lymphoma subtypes e.g. Sjögren's syndrome and extra-nodal marginal zone lymphoma of the salivary gland, and thyroid MALT lymphoma in a background of Hashimoto's thyroiditis. B and T-cell hyperactivity due to chronic antigenic stimulation and the consequent presence of acquired lymphoid tissue seems to play a key role in the pathogenesis of AI-related lymphomas...

Chylothorax is defined as the presence of chyle in the pleural cavity. Central vein thrombosis is an under-recognized cause of chylothorax in the adult population and is commonly related to central venous catheterization. Case 1 illustrates a patient with AIDS and disseminated tuberculosis with left chylothorax and central vein thrombosis after a month of antituberculosis therapy. Case 2 was a patient with advanced seminoma who presented with left chylothorax and central vein thrombosis while on chemotherapy...

PURPOSE: Given childhood cancer survivors' risk of treatment-induced late effects, long-term follow-up care is recommended. We explored experiences with late effects-related care and preferences for long-term follow-up care among adult survivors of childhood malignant lymphoma in Norway. METHODS: We conducted five focus group interviews with 34 survivors (19 females; 21 Hodgkin/13 non-Hodgkin lymphoma survivors; mean age 39 years; mean time from diagnosis 26 years)...

BACKGROUND: Patients infected with HIV have a significantly increased risk of developing non-Hodgkin lymphomas despite the widespread use of HAART. To investigate mTOR pathway activity in acquired immunodeficiency syndrome (AIDS) related diffuse large B-cell lymphoma AR-DLBCL, we used immunohistochemistry to examine the presence of the phosphorylated 70 ribosomal S6 protein-kinase (p70S6K), an extensively studied effector of mTOR Complex 1 (mTORC1) and the phosphorylated phosphatase and tensin homolog (pPTEN), a negative regulator of mTORC1 pathway...

Epstein-Barr virus (EBV) encodes 49 microRNAs (miRNAs) in the BART and BHRF1 regions of its genome. Although expression profiles of EBV-encoded miRNAs have been reported for EBV-positive cell lines and nasopharyngeal carcinoma, to date there is little information about total miRNA expression, including cellular and viral miRNAs, in the primary tumors of EBV-associated B-lymphoproliferative disorders. In this study, next-generation sequencing and quantitative real-time reverse transcription-PCR were used to determine the expression profiles of miRNAs in EBV-infected cell lines and EBV-associated B-cell lymphomas, including AIDS-related diffuse large B-cell lymphoma (DLBCL), pyothorax-associated lymphoma, methotrexate-associated lymphoproliferative disorder, EBV-positive DLBCL of the elderly, and Hodgkin lymphoma...

Selenium compounds such as methylseleninic acid (MSA) and sodium selenite (SS) have been widely evaluated as potential anti-cancer agents in the clinical setting. Primary effusion lymphoma (PEL) is a non-Hodgkin's B-cell lymphoma, associated with immunosuppressed individuals, such as post-transplant or AIDS patients. Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of PEL and Kaposi's sarcoma. Here, we found that MSA and SS markedly inhibited the growth of PEL cells compared with KSHV-uninfected B cells...

Retinal diseases generally are vision-threatening conditions that warrant appropriate clinical decision-making which currently solely dependents upon extensive clinical screening by specialized ophthalmologists. In the era where molecular assessment has improved dramatically, we aimed at the identification of biomarkers in 175 ocular fluids to classify four archetypical ocular conditions affecting the retina (age-related macular degeneration, idiopathic non-infectious uveitis, primary vitreoretinal lymphoma, and rhegmatogenous retinal detachment) with one single test...

Compromised apoptotic signaling is a prerequisite for tumorigenesis. The design of effective therapies for cancer treatment depends on a comprehensive understanding of the mechanisms that govern cell survival. The antiapoptotic proteins of the BCL-2 family are key regulators of cell survival and are frequently overexpressed in malignancies, leading to increased cancer cell survival. Unlike BCL-2 and BCL-XL, the closest antiapoptotic relative BCL-W is required for spermatogenesis, but was considered dispensable for all other cell types...

Previous studies have reported an increased risk for certain types of cancer in the HIV-infected population. The aim of this study was to assess the risk for cancer in people with AIDS (PWA) in comparison with the general population in São Paulo (Brazil), between 1997 and 2012. A population-based registry linkage study was carried out to assess the risk for cancer, using a standardized incidence ratio (SIR) approach. A total of 480 102 person-years, of which 337 941 (70.4%) person-years were men, were included in the analysis...
