Abstract
BACKGROUND Human immunodeficiency virus (HIV)-infected patients are at higher risk of malignancies. In addition to traditional determinants, a specific deleterious effect of HIV and immunodeficiency is speculated. We aimed at studying the association between immunological and virological characteristics of HIV-infected patients in care and the risk of acquired immunodeficiency syndrome (AIDS)-defining and non-AIDS-defining malignancies. METHODS Patients consecutively enrolled in the hospital-based Agence Nationale de Recherche sur le Sida (ANRS) CO3 Aquitaine Cohort were included if the duration of follow-up was >3 months during the period 1998-2006. Multivariate modeling used an extended Cox proportional hazards model for time-dependent covariates and delayed entry. RESULTS The 4194 patients included in the study developed 251 first malignancies during 22,389 person-years. A higher incidence of AIDS-defining malignancies (107 cases) was independently associated with (1) both longer and current exposures to a plasma HIV RNA level >500 copies/mL (hazard ratio [HR], 1.27 per year [P<.001] and 3.30 [P<.001], respectively) and (2) both longer and current exposure to a CD4(+) cell count <200 cells/mm(3) (HR, 1.36 per year [P<.001] and 6.33 [P<.001], respectively). A higher incidence of non-AIDS-defining malignancies (144 cases) was independently associated with longer and current exposure to a CD4(+) cell count <500 cells/mm(3) (HR, 1.13 per year [P=.01] and 2.07 [P<.001], respectively) and male sex (HR, 1.69; P=.02) but not with plasma HIV RNA level (P=.49 and P=.10 for cumulative and current exposures, respectively). CONCLUSIONS Uncontrolled plasma HIV RNA level was independently associated with a higher likelihood of developing AIDS-defining malignancies, whereas immunosuppression was associated with a higher risk of developing any type of malignancies. Antiretroviral treatment should aim at reaching and maintaining a CD4(+) count >500 cells/mm(3) to prevent the occurrence of malignancy, this should be integrated to malignancy-prevention policies.

Growth regulation of simian and human AIDS-related non-Hodgkin's lymphoma cell lines by TGF-beta1 and IL-6. BMC Cancer 2007; 7:35. [PMID: 17324269 PMCID: PMC1810304 DOI: 10.1186/1471-2407-7-35] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2006] [Accepted: 02/26/2007] [Indexed: 01/01/2023] Open
Abstract
Background AIDS-related non-Hodgkin's lymphoma (AIDS-NHL) is the second most frequent cancer associated with AIDS, and is a frequent cause of death in HIV-infected individuals. Experimental analysis of AIDS-NHL has been facilitated by the availability of an excellent animal model, i.e., simian Acquired Immunodeficiency Syndrome (SAIDS) in the rhesus macaque consequent to infection with simian immunodeficiency virus. A recent study of SAIDS-NHL demonstrated a lymphoma-derived cell line to be sensitive to the growth inhibitory effects of the ubiquitous cytokine, transforming growth factor-beta (TGF-beta). The authors concluded that TGF-beta acts as a negative growth regulator of the lymphoma-derived cell line and, potentially, as an inhibitory factor in the regulatory network of AIDS-related lymphomagenesis. The present study was conducted to assess whether other SAIDS-NHL and AIDS-NHL cell lines are similarly sensitive to the growth inhibitory effects of TGF-beta, and to test the hypothesis that interleukin-6 (IL-6) may represent a counteracting positive influence in their growth regulation. Methods Growth stimulation or inhibition in response to cytokine treatment was quantified using trypan blue exclusion or colorimetric MTT assay. Intracellular flow cytometry was used to analyze the activation of signaling pathways and to examine the expression of anti-apoptotic proteins and distinguishing hallmarks of AIDS-NHL subclass. Apoptosis was quantified by flow cytometric analysis of cell populations with sub-G1 DNA content and by measuring activated caspase-3. Results Results confirmed the sensitivity of LCL8664, an immunoblastic SAIDS-NHL cell line, to TGF-beta1-mediated growth inhibition, and further demonstrated the partial rescue by simultaneous treatment with IL-6. IL-6 was shown to activate STAT3, even in the presence of TGF-beta1, and thereby to activate proliferative and anti-apoptotic pathways. By comparison, human AIDS-NHL cell lines differed in their responsiveness to TGF-beta1 and IL-6. Analysis of a recently derived AIDS-NHL cell line, UMCL01-101, indicated that it represents immunoblastic AIDS-DLCBL. Like LCL-8664, UMCL01-101 was sensitive to TGF-beta1-mediated inhibition, rescued partially by IL-6, and demonstrated rapid STAT3 activation following IL-6 treatment even in the presence of TGF-beta1. Conclusion These studies indicate that the sensitivity of immunoblastic AIDS- or SAIDS-DLBCL to TGF-beta1-mediated growth inhibition may be overcome through the stimulation of proliferative and anti-apoptotic signals by IL-6, particularly through the rapid activation of STAT3.

Abstract
PURPOSE Morbidity and mortality related to neoplasia are increasing in HIV-infected patients. CURRENT KNOWLEDGE AND KEY-POINTS: The incidence of AIDS opportunistic infections dramatically decreased since the introduction of highly active antiretroviral therapy (HAART). Among AIDS-cancers, the incidences of Kaposi sarcoma and of cerebral lymphoma decreased in a same way than AIDS infections but the incidences of systemic non-Hodgkin lymphoma and of cervical cancer decreased less than the others and remain higher than in the general population. This suggests that other factors than the quantitative immune reconstitution could be implicated. The most recent and large studies have also shown a 1.7 to 3 fold increased risk of developing non-AIDS cancers in HIV-infected patients when compared to the general population without significant impact of HAART on incidence curves. These malignancies include Hodgkin disease, lung, anal, head and neck cancers, hemopathies, and conjunctival cancers. PERSPECTIVES Epidemiologic survey will help to define priorities in terms of prevention and screening in this specific population and to evaluate interventions which should be systematically proposed (alcohol and tobacco cessation programs, viral coinfection). The own roles of HIV itself and of antiretrovirals as prooncogenic factors need to be assessed.

Abstract
PURPOSE To determine incidence of non-AIDS-defining cancers (NADC) in HIV-infected patients before (P1) and during (P2) the use of highly active antiretroviral therapy (HAART) relative to that observed in the French general population (FGP) of the same age and sex. PATIENTS AND METHODS Sex- and age-adjusted NADC standardized incidence ratios (SIR), with FGP as reference, were estimated in 1992 to 1995 (P1) and in 1996 to 1999 (P2) in a French Hospital Database on HIV prospective hospital cohort study. RESULTS NADCs were diagnosed in 260 patients during P1 and 391 patients during P2 among the 77,025 patients included in the database between January 1, 1992, and December 31, 1999. Estimated incidence of all cancers was higher in HIV-infected men than in FGP during both periods (P1 SIR = 2.36 and P2 SIR = 1.91). No excess of cancers was observed among HIV-infected women in either period. Incidence of all cancers did not change from P1 to P2 in either sex (SIR = 0.96 for men and 1.00 for women). In contrast, incidence of Hodgkin's disease (HD) was higher than in FGP in both sexes and both periods and increased in P2 as compared with P1; incidence of lung cancer was higher in both sexes during P2. CONCLUSION Relative to FGP, the overall incidence of NADCs was increased in HIV-infected men but not in women and did not differ between P1 and P2. Only HD was much more common in HIV infection, and the potential role of HAART on HD cannot be excluded.

Abstract
AIDS-related non-Hodgkin lymphomas (AIDS-NHL) consistently derive from B-cells and are characterized by extreme clinical aggressiveness. At histological level, AIDS-NHL are classified as AIDS-related Burkitt's lymphoma (AIDS-BL), AIDS-related diffuse large cell lymphoma (AIDS-DLCL) and AIDS-related primary effusion lymphoma (AIDS-PEL). The role of cytokines in the pathogenesis and management of AIDS-NHL has been studied to a certain extent. Production of large quantities of human IL-10 occurs frequently in AIDS-BL and correlates with latent EBV infection of the tumor clone. Lesser amounts of the cytokine are released in EBV negative cases. The pathogenetic role of IL-10 in AIDS-BL is suggested by the observation that IL-10 antisense oligonucleotides inhibit proliferation of the lymphoma. A significant fraction of AIDS-BL cell lines produce TNFbeta. Among AIDS-NHL, the release of TNFbeta appears to be specific for AIDS-BL. The pathogenetic relevance of TNFbeta in lymphomagenesis is suggested by the observation that some BL cell lines use TNFbeta as an autocrine growth factor. Some cases of AIDS-BL, particularly those carrying EBV infection, also secrete IL-6, IL-7 and IL-12. With respect to AIDS-DLCL, many cases express the IL-6R, rendering these cells responsive to the paracrine stimulation by the IL-6 produced by nearby T-cells, macrophages and endothelial cells which are frequently abundant in these tumor samples. The tumor clone itself, however, generally fails to release IL-6. AIDS-PEL is characterized by secretion of large amounts of IL-6 and IL-10. Some PEL cases also release oncostatin M. Apart from human IL-6, PEL also express viral IL-6, which is encoded by the HHV-8 genome. The biological relevance of both IL-6 and IL-10 in PEL proliferation and growth has been recently clarified in vitro and in vivo. Overall, these data suggest that activation of different cytokine loops clusters with different clinico-pathologic categories of AIDS-NHL and may represent the potential target of novel therapeutic strategies.

Abstract
Infection with SIVmac251 in some rhesus monkeys (Macaca mulatta) leads to B-cell non-Hodgkin's lymphomas (B-NHL) clinically similar to that of HIV-infected AIDS patients. To further characterize the SIV-associated B-NHL we have generated genetic profiles of malignant cells by subtractive hybridization and Northern blot analysis. We have analyzed 21 clones of a subtracted cDNA library corresponding to overexpressed genes in diffuse large B-cell (DLBCL) SIV-associated monkey lymphoma. Eight of these clones represent a sequence homologous to an abundant transcript from KG-1 cells originally established from a human myelogenous leukemia. The protein encoded has a 60% similarity to a hypothetical glycine-rich transmembrane signal protein of Caenorhabditis elegans and 25% similarity to the ret finger protein. The other cDNA clones contained sequences of the serum amyloid A gene (SAA), the alpha1-acid glycoprotein gene (AGP), the ribosomal protein S3a (RPS3a) and L8 (RPL8) genes, the interferon-inducible gene (INF-ind), the metastasin gene (mts1), and the NADH dehydrogenase I gene (ND-I). The remaining cDNA clones consisted of yet unknown sequences. In addition, we detected an up-regulation of the cytochrome c oxidase II gene (COX-II), the ND-IV gene, and the SET oncogene by Northern blot hybridization in three SIV-associated NHLs of different histomorphological classification. All these genes have not previously been found to be overexpressed in B-NHL.

Abstract
In the US over one million persons are currently infected with the HIV, over half a million have had AIDS, and over 300,000 have died from AIDS. Worldwide, it is estimated that more than 17 million people are currently infected with HIV, and over 1,200,000 cases of AIDS have been reported to the World Health Organization. By some estimates, up to 40% of patients with AIDS will ultimately develop some form of cancer. Non-Hodgkin's lymphoma, Kaposi's sarcoma and invasive cervical cancer have a higher incidence in persons with HIV infection and all three are AIDS-defining illnesses. In addition, several reports suggest that a number of other malignancies may occur at an increased incidence in persons with HIV infection, including squamous-cell carcinoma of the head, neck and anus, plasmacytoma, melanoma, small-cell lung cancer, basal-cell cancer, and germ-cell tumours. Clinicians should become familiar with HIV-related malignancies as their incidence is expected to further increase as more effective therapies for HIV and associated opportunistic infections allow patients to live longer in an advanced state of immunodeficiency. In the current article, we will review the clinical and therapeutic aspects of the most common AIDS-related malignancies including non-Hodgkin's and Hodgkin's lymphomas, Kaposi's sarcoma and anogenital epithelial neoplasias.

Abstract
Lymphomas associated with human immunodeficiency virus (HIV) will probably become an increasing problem with improved survivals of infected individuals in an immunosuppressed state because of the advances in antiretroviral treatment and the therapy of opportunistic infections. In an attempt to aid the understanding of the many aspects of the this growing problem, the current thinking about the epidemiology, pathology, biological and clinical features, and treatment of the systemic HIV-associated non-Hodgkin lymphomas is reviewed. The important features of the HIV-associated central nervous system lymphomas are also described. Finally, there is a discussion of Hodgkin's disease in HIV-infected individuals.

Abstract
The pathogenesis of polyclonal HIV-associated lymphomas lacking traditional B cell cofactors (i.e., Epstein-Barr virus [EBV] infection, c-myc translocations) is poorly understood. A multistep pathogenesis model has been proposed in which polyclonal lymphomas represent an earlier stage in HIV-associated lymphomagenesis before the emergence of a dominant malignant clone. Chronically present antigens have been proposed as a likely stimulus for polyclonal B cell proliferation; if so, polyclonal lymphoma-associated immunoglobulins (Igs) should have molecular evidence of somatic hypermutation, a process by which antibody affinity maturation in response to chronic antigenic stimulation occurs. Molecular analyses of Ig heavy chain variable (V(H)) gene use by B cells in a polyclonal HIV-associated large cell lymphoma lacking EBV and c-myc rearrangement was undertaken. Eighteen randomly selected clones generated from RT-PCR yielded 15 unique V(H) sequences, all of which were most homologous to only three previously identified germline V(H)1 genes. Two sets of clones (consisting of three and two clones, respectively) had identical V(H) gene sequences, and one pair of clones had identical third complementarity determining regions (CDR3s) but different V(H) gene sequences; eight clones were <95% homologous to their most related germline V(H)1 genes. We compared these results with Ig V(H)1 gene use by B cells present in a reactive hyperplastic lymph node obtained from an HIV-1-infected individual. Fifteen clones randomly selected from RT-PCRs yielded 15 unique V(H)1 sequences, all of which were most homologous to 5 previously identified germline V(H)1 genes; 10 clones were <95% homologous to their most related germline gene. Binomial probability analysis revealed that only 1 of the 15 unique V(H)1 sequences derived from the polyclonal lymphoma (i.e., 7%), as compared with 5 of 15 unique V(H)1 sequences derived from the reactive lymph node (i.e., 33%), had a low probability of occurrence by random chance (p < 0.05). These data provide molecular evidence of polyclonality in an HIV-associated polyclonal lymphoma, demonstrate a qualitative difference in somatic hypermutations of Ig V(H) genes associated with malignant versus reactive B cell lymphoproliferations, and support an antigen-mediated multistep pathogenesis model of HIV-1-associated lymphomagenesis.

Abstract
Primary malignant lymphomatous effusions arising in individuals infected with the human immunodeficiency virus, type 1 (HIV-1) represent a rare subset of HIV-associated lymphomas. Previous studies have demonstrated that the malignant cells are monoclonal (as defined by rearrangement of the immunoglobulin gene), express cell surface CD38, and are infected with Epstein-Barr virus (EBV) and human herpes virus, type 8 (HHV-8). Despite these detailed molecular and immunophenotypic studies, clinical information on this disease entity is scant, prompting us to review the clinical features of eight cases seen at our institutions. All eight patients had total peripheral CD4+ lymphocytes < 200/microliter and presented with complaints related to body cavity distension. Routine laboratory values were nondiagnostic and yielded no prognostic information. Only two patients could tolerate and thus received chemotherapy with no obvious impact on their clinical course. The mean overall survival after diagnosis was 60 days (range 6-166 days). Four patients were examined at autopsy. The primary malignant lymphomatous effusion either was the immediate cause of death or contributed significantly to the death of only two. All four patients examined post mortem, however, had lymphomatous infiltration of serosal surfaces adjacent to the site of the primary malignant effusion. Molecular and immunologic studies performed on the malignant cells and effusion fluids revealed universal expression of cell surface CD38 and the presence of HHV-8 gene sequences, but in contrast with previous studies, only four had rearranged immunoglobulin genes or EBV present: IL-6 and IL-10 levels in the malignant effusion fluids were markedly elevated. In summary, this rare subset of HIV-associated lymphomas in our eight patients arose late in the course of HIV-associated disease, had a rapid clinical course, and was molecularly heterogeneous. A pathogenetic role for HHV-8 alone in this disease process is strengthened by our observation of four cases lacking EBV but containing HHV-8.
