Abstract
Classic Hodgkin lymphoma (CHL) is a unique form of lymphoid cancer featuring a heterogeneous tumor microenvironment and a relative paucity of malignant Hodgkin and Reed-Sternberg (HRS) cells with characteristic phenotype. Younger individuals (children, adolescents and young adults) are affected as often as the elderly, producing a peculiar bimodal age-incidence profile that has generated immense interest in this disease and its origins. Decades of epidemiological investigations have documented the populations most susceptible and identified multiple risk factors that can be broadly categorized as either biological or environmental in nature. Most risk factors result in overt immunodeficiency or confer more subtle alterations to baseline health, physiology or immune function. Epstein Barr virus, however, is both a risk factor and well-established driver of lymphomagenesis in a significant subset of cases. Epigenetic changes, along with the accumulation of somatic driver mutations and cytogenetic abnormalities are required for the malignant transformation of germinal center-experienced HRS cell precursors. Chromosomal instability and the influence of endogenous mutational processes are critical in this regard, by impacting genes involved in key signaling pathways that promote the survival and proliferation of HRS cells and their escape from immune destruction. Here we review the principal features, known risk factors and lymphomagenic mechanisms relevant to newly diagnosed CHL, with an emphasis on those most applicable to young people.

HIV positivity may not have a negative impact on survival in Epstein-Barr virus-positive Hodgkin lymphoma: A Japanese nationwide retrospective survey. Oncol Lett 2018; 16:3923-3928.

Abstract
There has been no comparative clinical study focused on differences in the clinical features of Epstein-Barr virus (EBV)+ Hodgkin lymphoma (HL) between HIV-positive and -negative cases. In a nationwide survey from 511 institutions in Japan, the present study investigated 16 EBV+ HIVpositive HL patients. To further clarify their characteristics in comparison with EBV+ HIVnegative HL (n=34) in the combination antiretroviral therapy era in Japan, the present study was performed. Results indicated that EBV+ HIVpositive HL frequently occurred in a younger population compared with EBV+ HIVnegative HL (P=0.0295), and that the EBV+ HIVpositive HL group was not associated with the nodular sclerosis subtype in the population who were below the age of 40. Notably, the EBV+ HIVpositive HL group had a significantly higher frequency of extra-nodal involvement (P=0.0214), including marrow invasion. In the advanced stage, 80% of those with EBV+ HIVpositive HL did not require dose-reduction and in the majority of cases, chemotherapy was completed. There were no significant differences in the complete remission rate (P=0.1961), overall survival (P=0.200) and progression-free survival (P=0.245) between EBV+ HIVpositive HL (median observational period, 23.5 months) and EBV+ HIVnegative HL (median observational period, 64.5 months), suggesting that HIV positivity may not have a negative impact on the clinical outcome of EBV+ HL. Notably, standard chemotherapy is effective and tolerable for EBV+ HL, regardless of HIV infection.

Abstract
The diagnosis of lymphoproliferative disorders associated with immunodeficiency can be challenging because many of these conditions have overlapping clinical and pathologic features and share similarities with their counterparts in the immunocompetent setting. There are subtle but important differences between these conditions that are important to recognize for prognostic and therapeutic purposes. This article provides a clinicopathologic update on how understanding of these B-cell lymphoproliferations in immunodeficiency has evolved over the past decade.

Abstract
Highly active antiretroviral therapy (HAART) for human immunodeficiency virus (HIV) infection has been widely available in industrialized countries since 1996; its widespread use determined a dramatic decline in acquired immunodeficiency syndrome (AIDS)-related mortality, and consequently, a significant decrease of AIDS-defining cancers. However the increased mean age of HIV-infected patients, prolonged exposure to environmental and lifestyle cancer risk factors, and coinfection with oncogenic viruses contributed to the emergence of other malignancies that are considered non-AIDS-defining cancers (NADCs) as a relevant fraction of morbidity and mortality among HIV-infected people twenty years after HAART introduction. The role of immunosuppression in the pathogenesis of NADCs is not well defined, and future researches should investigate the etiology of NADCs. In the last years there is a growing evidence that intensive chemotherapy regimens and radiotherapy could be safely administrated to HIV-positive patients while continuing HAART. This requires a multidisciplinary approach and a close co-operation of oncologists and HIV-physicians in order to best manage compliance of patients to treatment and to face drug-related side effects. Here we review the main epidemiological features, risk factors and clinical behavior of the more common NADCs, such as lung cancer, hepatocellular carcinoma, colorectal cancer and anal cancer, Hodgkin’s lymphoma and some cutaneous malignancies, focusing also on the current therapeutic approaches and preventive screening strategies.

Abstract
Hermansky Pudlak type 2 syndrome (HPS2) is a rare autosomal recessive primary immune deficiency caused by mutations on β3A gene (AP3B1 gene). The defect results in the impairment of the adaptor protein 3 (AP-3) complex, responsible for protein sorting to secretory lysosomes leading to oculo-cutaneous albinism, bleeding disorders and immunodeficiency. We have studied peripheral blood and lymph node biopsies from two siblings affected by HPS2. Lymph node histology showed a nodular lymphocyte predominance type Hodgkin lymphoma (NLPHL) in both HPS2 siblings. By immunohistochemistry, CD8 T-cells from HPS2 NLPHL contained an increased amount of perforin (Prf) + suggesting a defect in the release of this granules-associated protein. By analyzing peripheral blood immune cells we found a significant reduction of circulating NKT cells and of CD56(bright)CD16(-) Natural Killer (NK) cells subset. Functionally, NK cells were defective in their cytotoxic activity against tumor cell lines including Hodgkin Lymphoma as well as in IFN-γ production. This defect was associated with increased baseline level of CD107a and CD63 at the surface level of unstimulated and IL-2-activated NK cells. In summary, these results suggest that a combined and profound defect of innate and adaptive effector cells might explain the susceptibility to infections and lymphoma in these HPS2 patients.

Abstract
BACKGROUND Non-AIDS-defining cancers in HIV-infected patients in the highly active antiretroviral therapy era have increased. To our knowledge a comprehensive review of non-AIDS-related malignancies in New Orleans has not yet been conducted. METHODS Databases from main institutions in New Orleans were queried retrospectively for the years 2001 to 2011. The International Classification of Diseases, Ninth Revision codes were used to search for HIV infection and cancer comorbidity. RESULTS A total of 16 patients were diagnosed with lung cancer (mean age 50 years) with 81% of the patients presenting with advanced stages. In all, 20 (mean age 47 years) were diagnosed with anal cancer, and 35% presented in late stages. In all, 14 patients (mean age 42 years) were diagnosed with Hodgkin Lymphoma, and 64% were diagnosed at late stage. A total of 5 women (mean age 44 years) were diagnosed with breast cancer with 40% of them presenting at late stage. CONCLUSION Malignancies were diagnosed at late stages in the majority of the cases, presented with worse outcomes, and had higher recurrence rates. The role of HIV and other viruses (Epstein Barr virus, human papillomavirus) and the potential mechanisms or pathways of oncogene activation also need to be clarified.

Abstract
INTRODUCTION Although the incidence and prevalence of AIDS-defining malignancies has decreased in the era of highly active antiretroviral therapy (HAART), the incidence and prevalence of Hodgkin's lymphoma (HL) in the HIV-infected population continues to rise. Compared with the general population, HIV-infected patients exhibit a 5-10-fold increased risk for developing HL. METHODS A retrospective review of charts and electronic records from 2000-2010 at the HIV outpatient clinic (HOP)-Louisiana State University in New Orleans was conducted, and pathologically confirmed cases of HIV-HL were identified within this cohort. RESULTS We found a prevalence of 6.3 cases per 1,000 patients per year of HIV-HL over a period of 10 years in our HIV outpatient clinic. The mean absolute CD4 count before treatment was 284 cells/mm(3) and after treatment was 194 cells/mm(3). The average time from the diagnosis of HIV infection to the diagnosis of HIV-HL was 7.6 years. The most common histopathologic type was mixed cellularity followed by lymphocytic predominance. The majority of patients had 6 cycles delivered. In terms of HL staging 87% presented with advanced stages (III B or IV). To the best of our knowledge 5 out of the 14 patients remain alive. CONCLUSIONS Patients in our cohort were older than most patients identified in other cohorts. All of our patients had coexisting chronic illnesses associated with inflammation, as well as detectable HIV viral loads and CD4 count >200, suggesting a role for both HIV- and non-HIV-associated inflammation in HIV-HL pathogenesis in this population. The role of HIV virus and other oncogenic viruses (EBV, HPV, and others) in the pathogenesis of Hodgkin's lymphoma in this group of patients needs to be elucidated.

Abstract
Patients with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) are at increased risk for developing Hodgkin's lymphoma (HL), a risk that has not decreased despite the success of combination antiretroviral therapy (cART) in the modern era. HIV-associated HL (HIV-HL) differs from HL in non-HIV-infected patients in that it is nearly always associated with Epstein-Barr virus (EBV) and more often presents with high-risk features of advanced disease, systemic "B" symptoms, and extranodal involvement. Before the introduction of cART, patients with HIV-HL had lower response rates and worse outcomes than non-HIV-infected HL patients treated with conventional chemotherapy. The introduction of cART, however, has allowed for the delivery of full-dose and dose-intensive chemotherapy regimens with improved outcomes that approach those seen in non-HIV infected patients. Despite these significant advances, HIV-HL patients remain at increased risk for treatment-related toxicities and drug-drug interactions which require careful attention and supportive care to insure the safe administration of therapy. This paper will address the modern diagnosis, risk stratification, and therapy of HIV-associated HL.

Abstract
Neoplastic lymphoid proliferation may arise from immune deficiency or disordered regulation of the immune system. Often the neoplasms are associated with viral agents, such as Epstein-Barr virus, human immunodeficiency virus, or human herpes virus 8. Lymphoproliferative diseases have been documented in a variety of primary immune disorders. The most commonly encountered neoplastic lesion is diffuse large B-cell lymphoma (DLBCL), although Hodgkin lymphoma (HL), Burkitt lymphoma, and peripheral T-cell lymphomas and/or leukemias have also been documented in rare instances. We report a case of a 6-year-old girl with unclassifiable primary immunodeficiency diagnosed with 2 different clones of DLBCLs and subsequently developed lymphocyte-depleted, classical HL. Both neoplasms were associated with Epstein-Barr virus. To the best of our knowledge, this is the first reported occurrence of primary immune disorder-associated lymphoproliferative disease with sequential development of DLBCLs and HL in a pediatric patient. Thorough surveillance is paramount for accurate assessment of the associated lymphoproliferative disease and in ascertaining likely transformation to, or de novo evolution of a different lymphoid neoplasm. This is also important in evaluating treatment response with appropriate therapeutic adjustments if clinically indicated.

Abstract
Epidemiologic and molecular findings suggest that classical Hodgkin's lymphoma (CHL) is not a single disease but consists of more than one entity and may occur in different clinical settings. This review analyzes similarities and disparities among CHL entities arising in different host's conditions with respect to pathobiology parameters, therapeutic options, and outcome. For the purpose of this analysis, CHL entities have been subdivided according to the immune status of the host. In nonimmunosuppressed hosts, according to the age, CHL include pediatric, adult, and elderly forms, whereas, in immunosuppressed hosts, according to the type of immunosuppression, CHL include human immunodeficiency virus (HIV)-associated, iatrogenic, and post-transplant types. CHL entities in different settings are similar in morphology of neoplastic cells, expression of activation markers, and aberrations/activation of NFKB, JAK/STAT, and P13K/AKT pathways, but differ in the association with Epstein-Barr virus (EBV) infection, persistent B-cell phenotype, and cellular background composition. Large B-cell lymphomas resembling CHL may also be observed in the same clinical settings. These lesions, however, do not fulfill the diagnostic criteria of CHL and clinically display a very aggressive behavior. In this article, current treatment options for the CHL entities, especially for elderly CHL and HIV-associated CHL, are specifically reviewed. ABVD remains the gold standard both in nonimmunosuppressed or immunosuppressed hosts even if there are several data suggesting a possible improvement in outcome using the aggressive BEACOPP regimen in advanced stages. Refractory CHL, a clinical condition that may occur throughout the entire spectrum of CHL, is discussed separately.

Abstract
Hodgkin lymphoma (HL) represents one of the most common non-AIDS-defining cancers with an increasing incidence overtime. Clinically, patients present advanced stages of disease with extranodal involvement in the majority of cases. In the last years, significant improvements in the treatment of patients with HL and HIV infection have been achieved. In the lack of randomized trials, several phase II studies have showed that in the era of highly active antiretroviral therapy (HAART) the same regimens employed in HIV-negative patients with HL can be used in HIV setting with similar results. Moreover, in the last years the feasibility of high dose chemotherapy and peripheral stem cell rescue has allowed to save those patients who failed the upfront treatment. Finally, in the near future, a better integration of diagnostic tools (including PET scan), chemotherapy (including new drugs), radiotherapy, HAART, and supportive care will significantly improve the outcome of these patients.

Abstract
HIV-associated lymphoproliferative disorders represent a heterogeneous group of diseases, arising in the presence of HIV-associated immunodeficiency. The overall prevalence of HIV-associated lymphoma is significantly higher compared to that of the general population and it continues to be relevant even after the wide availability of highly active antiretroviral therapy (HAART) (1). Moreover, they still represent one of the most frequent cause of death in HIV-infected patients. Epstein-Barr virus (EBV), a γ-Herpesviruses, is involved in human lymphomagenesis, particularly in HIV immunocompromised patients. It has been largely implicated in the development of B-cell lymphoproliferative disorders as Burkitt lymphoma (BL), Hodgkin disease (HD), systemic non Hodgkin lymphoma (NHL), primary central nervous system lymphoma (PCNSL), nasopharyngeal carcinoma (NC). Virus-associated lymphomas are becoming of significant concern for the mortality of long-lived HIV immunocompromised patients, and therefore, research of advanced strategies for AIDS-related lymphomas is an important field in cancer chemotherapy. Detailed understanding of the EBV lifecycle and related cancers at the molecular level is required for novel strategies of molecular-targeted cancer chemotherapy The linkage of HIV-related lymphoma with EBV infection of the tumor clone has several pathogenetic, prognostic and possibly therapeutic implications which are reviewed herein.

Abstract
OBJECTIVE Post-transplant Hodgkin lymphoma (ptHL) is a rare but serious complication. We explored the clinical, phenotypic and genetic similarities and disparities between ptHL and classical Hodgkin lymphoma (cHL) in immunocompetent patients and sought proteins/pathways in ptHL that might have potential as therapeutic targets. RESEARCH DESIGN AND METHODS Eight ptHL cases in solid organ recipients (mean patient age 36 years; mean duration between organ transplant and onset of ptHL 80 months) were phenotypically and genotypically analyzed and the results were compared with known phenotypic and molecular characteristics of cHL. RESULTS All ptHL expressed CD15, CD30 and LMP-1 of EBV; the B-cell markers BOB-1, Oct2, CD79a and CD20 were more commonly expressed in ptHL versus cHL (100%, 86%, 50% and 38% in ptHL compared to 6%, 14%, 10% and 33% in cHL, respectively); all ptHL expressed phosphoinositide 3-kinase (PI3K) versus 81% of cHL; 2/6 (33%) ptHL displayed gains at 9p24 that were similar to cHL (32%). The JAK2 downstream pSTAT3 slightly predominated in ptHL versus cHL (60% versus 50%). Clonal immunoglobulin gene rearrangements were found in 2/4 cases. CONCLUSIONS ptHL and cHL are closely related, but not identical, neoplasms, with the primary differences being the strict association with EBV infection, persistent phenotypic B-cell signature and high expression of PI3K as well as the slightly CD4-depleted but TIA-1/Granzyme B-enriched cellular background composition in ptHL.

Abstract
In the past few years, there has been a greater understanding of the spectrum and biology of Hodgkin lymphoma (HL). In standard texts, HL is classified as 2 distinct entities, namely nodular lymphocyte-predominant HL and classical HL (CHL). However, recent evidence suggests that CHL is not a single disease. Although the mixed cellularity and lymphocyte-depleted subtypes might be part of a biologic continuum, the nodular sclerosis subtype has a distinct epidemiology, clinical presentation, and histology. Nodular sclerosis HL might also be related to primary mediastinal B-cell lymphoma and mediastinal gray-zone lymphomas. We present an update on the pathobiology of HL and discuss these biologic and clinical differences in this review.

Abstract
Among the most common HIV-associated lymphomas are Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL) with immunoblastic-plasmacytoid differentiation (also involving the central nervous system). Lymphomas occurring specifically in HIV-positive patients include primary effusion lymphoma (PEL) and its solid variants, plasmablastic lymphoma of the oral cavity type and large B-cell lymphoma arising in Kaposi sarcoma herpesvirus (KSHV)-associated multicentric Castleman disease. These lymphomas together with BL and DLBCL with immunoblastic-plasmacytoid differentiation frequently carry EBV infection and display a phenotype related to plasma cells. EBV infection occurs at different rates in different lymphoma types, whereas KSHV is specifically associated with PEL, which usually occurs in the setting of profound immunosuppression. The current knowledge about HIV-associated lymphomas can be summarized in the following key points: (1) lymphomas specifically occurring in patients with HIV infection are closely linked to other viral diseases; (2) AIDS lymphomas fall in a spectrum of B-cell differentiation where those associated with EBV or KSHV commonly exhibit plasmablastic differentiation; and (3) prognosis for patients with lymphomas and concomitant HIV infection could be improved using better combined chemotherapy protocols incorporating anticancer treatments and antiretroviral drugs.
