Abstract
Patients infected with human immunodeficiency virus-1 (HIV-1) have an increased incidence of B-cell lymphoma, even though HIV-1 does not infect B cells. The development of B-cell lymphomas appears to be related to the action of the HIV-1 transactivator protein (Tat), which is released from HIV-infected cells and penetrates uninfected B cells, affecting host cell gene expression. Upon chronic HIV-1 infection, Tat acts on the cells for a long time, probably allowing the cells to adapt to the presence of the viral protein. The aim of this work was to identify and study the mechanism of adaptation of cells to prolonged (chronic) exposure to HIV-1 Tat. We performed a comparative analysis of cells expressing Tat under the action of either an inducible promoter or a constitutive promoter, allowing us to model acute and chronic Tat effects, respectively. We found that the acute action of Tat leads to the suppression of cell proliferation, probably due to the downregulation of genes associated with replication and protein synthesis. In the case of chronic action of Tat, cell proliferation was restored and the expression of genes associated with the implementation of protective (antiviral) functions of the cell was increased. Analysis using proteasome inhibitors showed that in the case of chronic action, intense Tat proteolysis occurred, which could be the main mechanism of B-cell adaptation. Thus, B cells have a powerful mechanism to adapt to the entry of HIV-1 Tat, the efficiency of which may determine the frequency of lymphomagenesis in HIV-1-infected patients.

Abstract
BACKGROUND Drug-drug interactions between antiretroviral treatment (ART) and cytostatics may have a negative impact in the prognosis of people with HIV (PWH) and cancer. OBJECTIVE The objective of this study is to evaluate the impact of the implementation of interdisciplinary management and the type of ART in PWH diagnosed with lymphoid neoplasms. METHODS This is a multicentric, retrospective observational cohort study including PWH diagnosed with lymphoid neoplasm who started first-line chemotherapy between 2008 and 2020. Demographic, clinical and therapeutic variables were obtained from the electronic medical records and associated with 5-year progression-free survival (PFS) and overall survival (OS) using Cox proportional hazard models. RESULTS A total of 118 individuals were included. Boosted ART was being used in 55 (46.6%) cases at the time of neoplasm diagnosis. The Infectious Diseases or the Pharmacy Department was consulted before starting chemotherapy in 79/118 (66.9%) cases. Interdisciplinary management resulted in fewer subjects taking boosted ART (17.7% versus 71.8%, P < 0.001) and more subjects using unboosted integrase strand transfer inhibitor-based ART (74.7% versus 7.7%, P < 0.001). The use of boosted ART with chemotherapy was associated with worse 5-year PFS (P = 0.003) and 5-year OS (P = 0.016). There was a trend towards better 5-year PFS and OS when interdisciplinary management was implemented, with significant differences for individuals receiving boosted ART at neoplasm diagnosis (P = 0.0246 and P = 0.0329, respectively). CONCLUSIONS Our findings underscore the significant impact of the type of ART on the prognosis of PWH undergoing chemotherapy. Encouraging collaborative management between oncologists, pharmacists and HIV teams for these patients enhances PFS and OS rates.

Abstract
OBJECTIVES To address the paucity of HIV-related lymphoma (HRL)-specific prognostic scores for the Japanese population by analyzing domestic cases of HRL and constructing a predictive model. DESIGN A single-center retrospective study coupled with a review of case reports of HRL. METHODS We reviewed all patients with HRL treated at our hospital between 2007 and 2023 and conducted a comprehensive search for case reports of HRL from Japan using public databases. A multivariate analysis for overall survival (OS) was performed using clinical parameters, leading to the formulation of the HIV-Japanese Prognostic Index (HIV-JPI). RESULTS A total of 19 patients with HRL were identified in our institution, whereas the literature review yielded 44 cases. In the HIV-JPI, a weighted score of 1 was assigned to the following factors: age at least 45 years, HIV-RNA at least 8.0×10 4 copies/ml, Epstein-Barr virus-encoded small RNA positivity, and Ann Arbor classification stage IV. The overall score ranged from 0 to 4. We defined the low-risk group as scores ranging from 0 to 2 and the high-risk group as scores ranging from 3 to 4. The 3-year OS probability of the high-risk group [30.8%; 95% confidence interval (CI): 9.5-55.4%) was significantly poorer than that of the low-risk group (76.8%; 95% CI: 52.8-89.7%; P < 0.01). CONCLUSION This retrospective analysis established pivotal prognostic factors for HRL in Japanese patients. The HIV-JPI, derived exclusively from Japanese patients, highlights the potential for stratified treatments and emphasizes the need for broader studies to further refine this clinical prediction model.

Abstract
Adoptive cell therapies (ACTs) have revolutionized cancer immunotherapy, prompting exploration into their application against oncoviruses. Oncoviruses such as human papillomavirus (HPV), hepatitis B virus (HBV), hepatitis C virus (HCV), and Epstein-Barr virus (EBV) contribute significantly (12-25%) to human malignancies through direct or indirect oncogenic mechanisms. These viruses persistently or latently infect cells, disrupt cellular homeostasis and pathways, challenging current antiviral treatment paradigms. Moreover, viral infections pose additional risks in the setting of long-term cancer therapy and lead to morbidity and mortality. Virally encoded oncoproteins, which are tumor-restricted, immunologically foreign, and even uniformly expressed, represent promising targets for patient-tailored ACTs. This review elucidates the rationale for leveraging viral antigen-specific ACTs in combating viral-associated malignancies. On this basis, ongoing preclinical studies consolidate our understanding of harnessing ACTs against viral malignancies, underscoring their potential to eradicate viruses implicated in cancer progression. Furthermore, we scrutinize the current landscape of clinical trials focusing on virus-specific ACTs and discuss their implications for therapeutic advancement.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of lymphoma worldwide, accounting for up to 40% of new non-Hodgkin Lymphoma (NHL) globally. People living with HIV are up to 17 times more likely to develop NHL, and as such, DLBCL is the leading cause of cancer death in this high-risk population. While histologically indistinguishable, HIV-associated (HIV+) and HIV-negative (HIV-) DLBCL are molecularly distinct, and biological differences may have implications for the development of future therapeutic interventions. Further, the impact of immunologic differences in people with HIV, including preceding ART, remains largely unknown. Here, we investigate the impact of HIV infection and ART exposure on the clinical features of DLBCL and T-cell immune response by performing imaging mass cytometry on our unique patient cohort in Malawi. In this cohort, HIV infection is positively prognostic, and HIV+/ART-naïve patients have the best outcomes. No established biomarkers other than Ki67 are associated with HIV or ART status, and the only tumour-intrinsic biomarkers that remain prognostic are MYC and MYC/BCL2 protein co-expression. Finally, TCR clonality is associated with distinct tumour-T cell interactions by HIV/ART status, indicating differential anti-tumour immune responses. We demonstrate previously undescribed HIV and ART-related differences in the DLBCL tumour microenvironment.

Abstract
The immune deficiency associated with human immunodeficiency virus (HIV) infection causes a distinct increased risk of developing certain cancer types. Kaposi sarcoma (KS), invasive cervical cancer and non-Hodgkin's lymphoma (NHL) are the prominent malignancies that manifest as a result of opportunistic viral infections in patients with advanced HIV infection. Despite the implementation of antiretroviral therapy (ART), the prevalence of these acquired immunodeficiency syndrome (AIDS)-defining malignancies (ADMs) remains high in developing countries. In contrast, developed countries have experienced a steady decline in the occurrence of these cancer types. However, there has been an increased mortality rate attributed to non-ADMs. Here, we provide a review of the molecular mechanisms that are responsible for the development of ADMs and non-ADMs which occur in HIV-infected individuals. It is evident that ART alone is not sufficient to fully mitigate the potential for ADMs and non-ADMs in HIV-infected individuals. To enhance the diagnosis and treatment of both HIV and malignancies, a thorough comprehension of the mechanisms driving the development of such cancers is imperative.

Abstract
OBJECTIVE To analyze the factors associated with survival in the largest cohort of individuals with HIV and lymphoma so far described in Brazil. DESIGN A retrospective, observational, multicenter study involving five institutions in São Paulo, Brazil. METHODS The medical records of consecutive patients with HIV diagnosed with lymphoma between January 2000 and December 2019 were screened. Inclusion criteria consisted of age over 17 years and a biopsy-confirmed diagnosis of lymphoma. The data collected included age, sex, staging (Ann Arbor system), duration of HIV infection, CD4 + lymphocyte count, HIV viral load, lactate dehydrogenase, erythrocyte sedimentation rate and serum beta-2-microglobulin levels, treatment and outcome. RESULTS Overall, 276 patients were included. Median age was 42 years. Most patients were male (74.3%) and with an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 (28.6% and 46.4%, respectively). Most had non-Hodgkin lymphomas (89.2%, n = 246), particularly diffuse large B-cell lymphoma (40.9%) and Burkitt lymphoma (26.4%). Hodgkin lymphoma accounted for 9.4%. Advanced stages III/IV were predominant (86.8%). HIV viral load at the moment of lymphoma diagnosis was detectable in 52.9% of patients. A CD4 + cell count of <200 cells/μl was recorded for 53% of the patients. Most patients (62.4%) were on combination antiretroviral therapy. The factors that significantly affected survival were: the ECOG performance status, lymphoma subtype, staging, beta-2-microglobulin level, central nervous system (CNS) infiltration, site of CNS infiltration, relapsed/refractory lymphoma and International Prognostic Index score. CONCLUSIONS HIV status, CD4 + -lymphocyte count and relapsed/refractory disease affected survival. Rituximab did not appear to improve outcome in HIV-related lymphomas.

Abstract
An increased frequency of B-cell lymphomas is observed in human immunodeficiency virus-1 (HIV-1)-infected patients, although HIV-1 does not infect B cells. Development of B-cell lymphomas may be potentially due to the action of the HIV-1 Tat protein, which is actively released from HIV-1-infected cells, on uninfected B cells. The exact mechanism of Tat-induced B-cell lymphomagenesis has not yet been precisely identified. Here, we ectopically expressed either Tat or its TatC22G mutant devoid of transactivation activity in the RPMI 8866 lymphoblastoid B cell line and performed a genome-wide analysis of host gene expression. Stable expression of both Tat and TatC22G led to substantial modifications of the host transcriptome, including pronounced changes in antiviral response and cell cycle pathways. We did not find any strong action of Tat on cell proliferation, but during prolonged culturing, Tat-expressing cells were displaced by non-expressing cells, indicating that Tat expression slightly inhibited cell growth. We also found an increased frequency of chromosome aberrations in cells expressing Tat. Thus, Tat can modify gene expression in cultured B cells, leading to subtle modifications in cellular growth and chromosome instability, which could promote lymphomagenesis over time.

Abstract
PURPOSE OF REVIEW To summarize the recent evidence on the pathology, current standard of care and recent advances in the treatment of HIV-related lymphomas. RECENT FINDINGS Lymphomas remain a major cause of morbidity and mortality in people living with HIV, even in the era of combination antiretroviral therapy (cART). However, treatment outcomes for these malignancies have improved in recent decades, due to full-dose chemotherapy, effective cART and supportive care. Recent advances include the identification of novel driving signaling pathways as promising molecular targets to improve lymphoma outcomes. SUMMARY Patients with HIV-related lymphomas who receive effective cART should be treated like the general population.

Abstract
Few data exist on Epstein-Barr virus (EBV) prevalence across the full spectrum of lymphoma subtypes, particularly in sub-Saharan Africa. The objective of our study was to test the presence of EBV in a nationally representative sample of malignant lymphomas diagnosed in the Butaro Cancer Center of Excellence (BCCOE) in Rwanda. Of 102 Hodgkin (HL) and 378 non-Hodgkin lymphomas (NHL) diagnosed in BCCOE between 2012 and 2018, 52 HL and 207 NHL were successfully tested by EBV-encoding RNA in situ hybridization. EBV prevalence was 54% in HL, being detected in all classical HL subtypes: mixed-cellularity (n = 3/8), nodular-sclerosis (n = 7/17) and lymphocyte-rich (n = 2/3). EBV prevalence was 9% in NHL, being 10% among 158 B-cell NHL, 3% among 35 T-cell NHL and the single NK-cell NHL was EBV-positive. Among B-cell NHL, EBV was present in the majority of Burkitt (n = 8/13), and was also rarely detected in follicular (n = 1/4) and acute B-cell lymphoblastic (n = 1/45) lymphomas. Five of the 45 (11%) diffuse large B-cell lymphomas (DLBCLs) were EBV-positive, including three out of five plasmablastic lymphoma (PBL). Of 39 HL and 163 NHL of known human immunodeficiency virus (HIV) status, 2 (5%) and 14 (9%) were HIV-positive, respectively, of which only four were also EBV-positive (2 PBL, 2 HL). In summary, we report rare regional-level data on the association of EBV with classical HL, Burkitt and DLBCLs, and report sporadic detection in other subtypes possibly related to EBV. Such data inform the burden of disease caused by EBV and can help guide application of future advances in EBV-specific prevention and therapeutics.

Meer S, Perner Y, Willem P. Oral versus extra-oral plasmablastic lymphoma: A comparative analysis of 101 cases. J Oral Pathol Med 2021; 51:146-151. [PMID: 34910327 DOI: 10.1111/jop.13269] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 11/22/2021] [Accepted: 12/08/2021] [Indexed: 11/28/2022]
Abstract
AIMS Originally described exclusively orally in HIV-infected patients, plasmablastic lymphoma (PBL) is increasingly described extra orally and in non-HIV-infected persons. The study comparatively analysed the clinico-pathologic features of oral PBLs (n = 55) to previously published extra-oral PBLs (n = 45 + 1) diagnosed over a seven-year period at the same institution in an HIV prevalent setting in South Africa in order to clarify any distinction between oral and extra-oral PBLs. METHODS AND RESULTS Tumours were assessed histologically and immunohistochemically with CD45 (LCA), CD3, CD20, CD79a, PAX5, CD138, MUM1, BLIMP1, VS38c, Ki-67, BCL6 and CD10 using standard protocols. Age ranged from 22 to 76 years (oral) and 9 and 59 years (extra-oral). Most PBL patients were HIV positive [oral (84%); extra-oral (65%)]. Male:female ratio was 2.7:1 for oral and 1.4:1 for extra-oral PBLs. Favoured oral and extra-oral sites were the maxilla and anus. PBLs displayed an indistinguishable immunohistochemical profile with unusually high CD45 expression (oral: 98%, extra-oral: 84%). EBV assessed by chromogenic in situ hybridisation (ISH) showed positivity in all oral PBLs and 95% extra-oral PBLs. MYC rearrangements (fluorescence ISH MYC break-apart probe) were similar in all the PBLs. CONCLUSIONS Extra-oral PBL is identical to its oral counterpart in gender and age distribution, HIV status, morphological appearances, immunophenotypic profile and EBV association. PBL should be regarded as the same tumour irrespective of oral or extra-oral site of origin.

Abstract
The pathogenesis of plasmablastic lymphoma (PBL) involves the Epstein-Barr virus (EBV), human immunodeficiency virus (HIV), and MYC gene aberrations. We aimed to determine the EBV latent infection pattern and frequency of MYC gene aberrations in PBLs. Immunohistochemistry was performed using antibodies for EBNA1, EBNA2, and LMP1 while fluorescence in situ hybridization was performed using a MYC probe. The patient cohort comprised 49 adult cases (44 were HIV-positive and three were HIV-negative). Forty-one cases were EBV-positive with 11 EBNA1-positive cases, all cases EBNA2-negative, and four LMP1-positive cases. Latency 0 was determined in 29 cases, latency I in eight cases, and latency II in four cases. The MYC gene was rearranged in eight cases, showed copy number alterations in 11 cases and, no rearrangement in 11 cases. This is the largest cohort of PBLs from South Africa to show a predominantly restricted EBV latency pattern with MYC gene aberrations as a common finding.

Abstract
Cancer arises from the accumulation of genetic and epigenetic alterations. Even in the era of precision oncology, carcinogens contributing to neoplastic process are still an important focus of research. Comprehensive genomic analyses have revealed various combinations of base substitutions, referred to as the mutational signatures, in cancer. Each mutational signature is believed to arise from specific DNA damage and repair processes, including carcinogens. However, as a type of carcinogen, tumor viruses increase the cancer risk by alternative mechanisms, including insertional mutagenesis, viral oncogenes, and immunosuppression. In this review, we summarize virus-driven carcinogenesis to provide a framework for the control of malignant cell proliferation. We first provide a brief overview of oncogenic viruses and describe their implication in virus-related tumors. Next, we describe tumor viruses (HPV, Human papilloma virus; HBV, Hepatitis B virus; HCV, Hepatitis C virus; EBV, Epstein-Barr virus; Kaposi sarcoma herpesvirus; MCV, Merkel cell polyoma virus; HTLV-1, Human T-cell lymphotropic virus, type-1) and tumor virus-related cancers. Lastly, we introduce emerging tumor virus candidates, human cytomegalovirus (CMV), human herpesvirus-6 (HHV-6) and adeno-associated virus-2 (AAV-2). We expect this review to be a hub in a complex network of data for virus-associated carcinogenesis.
