We prospectively evaluated 28 triple-class experienced HIV-1-infected patients harbouring R5 virus, who received maraviroc, raltegravir and etravirine. By on-treatment analysis, 26 (92%) had less than 50 copies HIV-RNA/ml at week 48. The median (interquartile range) 48-week increase in CD4 cell counts was 267 (136-355) cells/microl. Three serious adverse events occurred: one recurrence of mycobacterial spondylodiscitis, one anal cancer, one Hodgkin lymphoma. Although long-term safety needs further study, this protease inhibitor and nucleoside analogue-sparing regimen showed sustained efficacy.

Since the first reports between the association of Human Immunodeficiency Virus (HIV) infection and neoplasia, there has been a dramatic change in the incidence and epidemiology of AIDS-related malignancies. Kaposi sarcoma (KS), non-Hodgkin's lymphomas (NHL), and cervical cancer are classified by the Centers for Disease Control and Prevention (CDC) as AIDS-defining malignancies. However, since the availability of highly active combination antiretroviral therapy (cART), especially protease inhibitors, there has been a steady increase in non- AIDS defining malignancies, such as Hodgkin's lymphoma (HL), lung cancer, hepatocellular cancer, anal cancer and others and a decline in AIDS-defining neoplasias. Although the emergence of non-AIDS defining cancers could be a result of longer life expectancy and due to a better control of HIV, toxic habits and co-infection with other viruses such as hepatitis B, hepatitis C and human papilloma virus (HPV) could play an important role. The interactions of cART and incomplete immune reconstitution could be other factors explaining the increase in non-AIDS defining cancers. These emerging non-AIDS defining malignancies present a new challenge in the care of patients with HIV infection, and require optimal treatment protocols that take into consideration the interaction between cART and systemic chemotherapy. We review the current status of AIDS-related malignancies, its pathophysiology, epidemiology and management with emphasis in the changing patterns of presentation.

Technological innovations such as web services and collaborative Grid platforms like caGrid can create opportunities to converge the worlds of health care and clinical research, by facilitating access and integration of HIV-related malignancy clinical and outcomes data at more sophisticated, semantic levels. At the same time, large numbers of randomized clinical trial and outcomes data on AIDS-defining malignancies (ADM) and non-AIDS-defining malignancies (nADM) have been produced during the last few years. There is still much work to do, though, on obtaining clear conclusions from the integration of such information. This is a white paper on work in progress from Emory University's HIV/AIDS related malignancy data integrative knowledge base project (HIV-K). We are working to increase the understanding of available clinical trial data and outcomes of ADM such as lymphoma, as well as nADM such as anal cancer, Hodgkin lymphoma, or liver cancer. Our hypothesis is that, by creating prototypes of tools for semantics-enabled integrative knowledge bases for HIV/AIDS-related malignancy data, we will facilitate the identification of patterns and potential new overall evidence, as well as the linking of integrated data and results to registries of interest.

Since no large descriptive studies of incident cancers in HIV-infected patients are available in France, the nationwide cross-sectional ONCOVIH study aimed to prospectively report new malignancies diagnosed in HIV-infected patients in cancer centers and HIV/AIDS centers. We estimated the number of cancers in France for the year 2006 using the capture-recapture methods with two sources: ONCOVIH and the FHDH ANRS-CO4 cohort, as well as the completeness of the sources. Incidence and relative risks (RR) to the general population were estimated. In 2006, 672 new malignancies in 668 patients were reported in ONCOVIH; the most common were non Hodgkin's lymphoma (NHL, 21.5%), Kaposi's sarcoma (KS, 16.0%), lung cancer (9.4%), anal cancer (8.2%), Hodgkin's lymphoma (7.6%), skin cancers excluding melanoma (6.8%), and liver cancer (5.6%). Based on the capture-recapture approach, the estimated number of malignancies was 1320 and non-AIDS-defining malignancies (NADM) represented 68% of cases. The overall ascertainment of malignancies were 53%, and 59%, in the ONCOVIH study, and the FHDH ANRS-CO4 cohort, respectively. The estimated incidence of cancer among HIV-infected patients was 14 per 1000 person-years. Compared with the general population, the estimated RR in HIV-infected patients was 3.5 (95%CI 3.3-3.8) in men and 3.6 (95%CI 3.2-4.0) in women, and was particularly elevated in younger patients. Even in the era of combined antiretroviral therapy, the incidence of cancer is higher in HIV-infected persons than in the general population. A large variety of malignancies were diagnosed, and the majority were NADM.

The introduction of highly active antiretroviral therapy (HAART) has drastically changed the scope and spectrum of diseases associated with HIV, shifting from AIDS-related to non-AIDS-related diseases. Studies linking HIV/AIDS databases to cancer registries have shown a dramatic decrease in AIDS-related malignancies and a steady increase in non-AIDS-defining malignancies (NADM). We review the causes underlying the rise in incidence of NADM and the clinical presentation, pathology, and treatment outcomes of the four most commonly encountered NADM in the HAART era. Meta-analysis of published studies show an increase in NADM over the general population, mostly among infection-related cancers such as anal cancer, Hodgkin lymphoma, and liver cancer. Among the non-infection-related cancers, lung and skin cancers predominate. The overall effect of HAART on NADM is unsettled. As HIV-infected individuals survive longer, better screening strategies are needed to detect cancer earlier, and prospective data are needed to assess the impact of HAART on cancer outcomes.

Exfoliative and aspiration cytologies play a major role in the management of patients with human immunodeficiency virus infection. Common cytology samples include cervicovaginal and anal Papanicolaou tests, fine needle aspirations, respiratory specimens, body fluids, Tzanck preparations, and touch preparations from brain specimens. While the cytopathologists need to be aware of specific infections and neoplasms likely to be encountered in this setting, they should be aware of the current shift in the pattern of human immunodeficiency virus-related diseases, as human immunodeficiency virus patients are living longer with highly active antiretroviral therapy and suffering fewer opportunistic infections with better antimicrobial prophylaxis. There is a rise in nonhuman immunodeficiency virus-defining cancers (e.g., anal cancer, Hodgkin's lymphoma) and entities (e.g., gynecomastia) from drug-related side effects. Given that fine needle aspiration is a valuable, noninvasive, and cost-effective tool, it is frequently employed in the evaluation and diagnosis of human immunodeficiency virus-related diseases. Anal Papanicolaou tests are also increasing as a result of enhanced screening of human immunodeficiency virus-positive patients for cancer. This paper covers the broad spectrum of disease entities likely to be encountered with human immunodeficiency virus-related cytopathology.

Non-AIDS-defining cancers are a rising health concern among HIV-infected patients. Cancer screening is now an important component of health maintenance in HIV clinical practice. The decision to screen an HIV-infected patient for cancer should include an assessment of individualized risk for the particular cancer, life expectancy, and the harms and benefits associated with the screening test and its potential outcome. HIV-infected patients are at enhanced risk of several cancers compared to the general population; anal cancer, hepatocellular carcinoma, Hodgkin's lymphoma, and lung cancer all have good evidence demonstrating an enhanced risk in HIV-infected persons. A number of cancer screening interventions have shown benefit for specific cancers in the general population, but data on the application of these tests to HIV-infected persons are limited. Here we review the epidemiology and background literature relating to cancer screening interventions in HIV-infected persons. We then use these data to inform a conceptual model for evaluating HIV-infected patients for cancer screening.

The eruption of Kaposi sarcoma (KS) and aggressive non-Hodgkin lymphoma (NHL) in young homosexual men in 1981 in the West heralded the onset of the human immunodeficiency virus (HIV) infection epidemic, which remains one of the biggest challenges to global public health and science ever. Because KS and NHL were increased >10,000 and 50-600 times, respectively, with HIV, they were designated AIDS defining cancers (ADC). Cervical cancer (CC), increased 5-10 times was also designated as an ADC. A few other cancers are elevated with HIV, including Hodgkin lymphoma (10 times), anal cancer (15-30 times), and lung cancer (4 times) are designated as non-AIDS defining cancers (NADCs). Since 1996 when combination antiretroviral therapy (cART) became widely available in the West, dramatic decreases in HIV mortality have been observed and substantial decrease in the incidence of ADCs. Coincidentally, the burden of NADCs has increased as people with HIV age with chronic HIV infection. The impact of HIV infection on cancer in sub-Saharan Africa, where two thirds of the epidemic is concentrated, remains poorly understood. The few studies conducted indicate that risks for ADCs are also increased, but quantitatively less so than in the West. The risks for many cancers with established viral associations, including liver and nasopharynx, which are found in Africa, do not appear to be increased. These data are limited because of competing mortality, and cancer is under diagnosed, pathological confirmation is rare, and cancer registration not widely practiced. The expansion of access to life-extending cART in sub-Saharan Africa, through programs such as the Global Fund for AIDS, Malaria, and Tuberculosis and the US President's Emergency Program for AIDS Relief (PEPFAR), is leading to dramatic lengthening of life of HIV patients, which will likely influence the spectrum and burden of cancer in patients with HIV. In this paper, we review current literature and explore merits for integrating cancer research in established HIV programs to obtain timely data about the incidence and burden of cancer in HIV-infected persons in Africa.

Fibrosarcoma is a malignant mesenchymal neoplasm of fibroblasts that rarely affects the oral cavity and can cause local recurrences or metastasis. Fibrosarcomas account for 15% of all soft tissue sarcomas, which represent only 1% of all malignant tumors of the head and neck region. The clinical behavior of the fibrosarcoma is characterized by a high local recurrence rate, and low incidence of loco regional lymph node and/or distant hematogenous metastasis. The etiology for fibrosarcoma has no definite cause but is thought to occur from preexisting lesions or in previously irradiated areas of bone lesions. Immunosuppression associated with HIV infection and acquired immune deficiency syndrome (AIDS) has been consistently linked to various cancers, including Kaposi's sarcoma, non-Hodgkin's lymphoma, and invasive cervical cancer. Rare neoplasms like Hodgkin's disease, anal cancer, leukemia, basal cell carcinoma, and squamous cell carcinoma have also been demonstrated. This paper presents one such a rare incidence of an intraosseous fibrosarcoma occurring in an HIV-positive patient.

The natural history of HIV infection has been greatly changed by the introduction of highly active antiretroviral therapy (HAART). As a consequence of improved immune function, the incidence of AIDS-defining cancers (ADCs), such as Kaposi's sarcoma, non-Hodgkin's lymphoma (NHL) and invasive cervical cancer, has significantly declined. On the contrary, non-AIDS-defining cancers (NADCs), such as hepatocellular carcinoma, anal cancer, lung cancer, colorectal cancer and Hodgkin's lymphoma, have gradually emerged as a major fraction of the overall cancer burden. The reasons are still partially unknown. Some of the increased risk may be explained by a high prevalence of cancer risk factors, such as smoking, alcohol consumption, human papilloma virus (HPV) infection and HCV infection among HIV-infected people. The role of immunosuppression in the development of NADCs is controversial, as several studies have not found a clear-cut evidence of an association between the degree of immunosuppression and the development of NADCs. Analogously, the impact of HAART is still not well defined. Future research should focus on the etiology of NADCs, in order to shed light on the pathogenesis of cancer and ultimately to work for prevention; moreover, additional studies should evaluate the best therapeutic approaches to NADCs and the impact of cancer screening interventions among HIV-infected people, in an effort to diagnose cancer at an earlier stage.
