3 Cancer Incidences in HIV in USA Number of people living with AIDS, AIDS-defining cancers, non-AIDS-defining cancers, and all cancers in the USA during 1991–2005.Cancer Incidences in HIV in USANumber of people living with AIDS, AIDS-defining cancers, non-AIDS-defining cancers, and all cancers in the United States during 1991–2005. A) US AIDS population by calendar year and age group. B) The estimated counts and standardized rates of AIDS-defining cancers among people living with AIDS in the United States by calendar year and age group. C) The estimated counts and standardized rates of non-AIDS-defining cancers among people living with AIDS in the United States by calendar year and age group. Of note, the bars for 0–12 year olds in panels (B) and (C) are difficult to see because of small numbers of cancers in this age group during 1991–2005 (122 AIDS-defining cancers and 25 non-AIDS-defining cancers). D) The estimated counts and standardized incidence rates of total cancers among people living with AIDS in the United States, stratified by AIDS-defining cancers, non-AIDS-defining cancers, and poorly specified cancers. Bars depict the estimated number of cancers, and points connected by lines depict incidence rates standardized to the 2000 US AIDS population by age group, race, and sex.Shiels M S et al.

21 Hodgkin’s Disease Association with HIV-infection Hodgkin’s disease: RR: 5 to 30Non-Hodgkin’s disease: RR: 24 to 165Incidence increasing rapidly in post HAART era>95% are EBV+Patients with HIV present with:B symptoms (70% to 96%), worse histology, higher-stage tumor (74% to 92% are III or IV), bone marrow involvement (40% to 50%), pancytopeniaGood response to MOPP/ABVComplete response: 74.5%2-year disease-free survival: 62% but more relapses in HIVEarly good results with Stanford V, BEACOPP and brentuximab vendotinSlide #32: Hodgkin’s DiseaseHodgkin’s disease is associated with HIV disease, however this association is lower than that seen with non-Hodgkin’s lymphoma (relative risk: 5-30 vs , respectively).1,2HIV-infected patients diagnosed with Hodgkin’s disease frequently present with:1,2B symptoms that are typically associated with poorer prognoses. These symptoms include fever, night sweats, and loss of more than 10% of body weight.Higher grade of disease than is found in newly diagnosed patients who are not HIV-positive.<1% of all patients with Hodgkin’s disease exhibit lymphocyte depletion. However, most of these cases are found in patients with HIV.Indicative if advanced disease, there is a greater chance of bone marrow involvement and pancytopenia being present at diagnosis.The MOPP/ABV regimen has produced good results, with a complete response rate of 74.5% and a 2-year disease-free survival rate of 62%.3ReferencesSpina M, Vaccher E, Nasti G, Tirelli U.

23 Kaposi’s Sarcoma One of the first recognized AIDS-defining illnesses Vascular tumor that may involve mucocutaneous, lymphatic, gastrointestinal, and pulmonary sitesHuman herpesvirus-8 (HHV8) or KSHVHHV8DNA virus found in both HIV+ and HIV- KS.Tropism for B cells and endothelial cells, high titers in salivaAlso associated with primary effusion lymphoma, Castleman’s disease, and angioimmunoblastic lymphadenopathy in HIVGenome codes for viral homologs of human proteins involved in cell cycle regulation and signalingHIV- and Kaposi’s sarcoma-induced angiogenic and inflammatory cytokines also stimulate Kaposi’s sarcoma cell growthSlide #8: Characteristics of Malignancies in AIDSKaposi’s sarcoma was one of the first AIDS-defining conditions.1Once a rare cancer of elderly men of Mediterranean origin, it became epidemic in the early years of AIDS.Virus associated with Kaposi’s sarcoma.1Kaposi’s sarcoma-associated herpesvirus (KSHV), also known as human herpes virus-8 (HHV8).HHV8 is sexually transmitted although it is not found in high concentrations in semen.2Recent research has detected viral replication in the oropharynx, suggesting an oral route of transmission. If true, then high-risk behaviors would be expanded to include “deep kissing” and oral/genital contact; and it would be expected that high rates of infection would be seen within the heterosexual community. Instead, the prevalence of HHV8 in heterosexuals is low, and MSMs are more likely to develop Kaposi’s sarcoma than their heterosexual counterparts, except in Africa where the incidence of Kaposi’s sarcoma is approximately equal in the two genders. The possibility of oral transmission of KSHV raises many unanswered questions.Levine and Tulpule observed that while HAART has been directed at reducing HIV-induced immunosuppression, it has also been associated with a drop in the incidence of Kaposi’s sarcoma. The study of Kaposi’s sarcoma thus could yield insight into pathogenesis-based therapeutic interventions.3ReferencesOsmond DH, Buchbinder S, Cheng A, et al.

32 Treatments for Kaposi’s Sarcoma Local1Systemic1,2Radiation therapyPhotodynamic (laser) therapyCryotherapyAlitretinoin gel – 9-cis retinoic acid (topical)Antiretroviral therapyLiposomal anthracyclinesPaclitaxelBleomycinVinca alkaloidsGemcitabineAlpha InterferonSlide #9: Treatment for Kaposi’s SarcomaKaposi’s sarcoma lesions may be treated locally with various therapies.1Efficacy of local radiation is variable, but this treatment may result in complete remission for some patients.Photodynamic (laser) therapy, intralesional chemotherapy (vinblastine or vincristine),cryotherapy, alitretinoin topical gel.Recurrence following remission induced by local therapy is quite common.Systemic therapy is useful for the treatment of visceral lesions that do not respond to other therapies, but efficacy varies greatly among patients.1,2Interferon-alfa has a 30% response rate. Flu-like symptoms, neutropenia, peripheral neuropathy, and central nervous system effects are dose-limiting toxicities for this treatment.Liposomal anthracyclines are recommended as first-line therapy for advanced Kaposi’s sarcoma.Paclitaxel is recommended as second-line therapy for those who have failed the anthracyclines.Other systemic therapies include bleomycin, vinca alkaloids (such as vinblastine, vincristine, and vinorelbine), cytokines, retinoids, and antivirals, such as cidofovir.Toxicity is common with systemic therapy and may range from hair loss to myelosuppression and neurotoxicity, depending on the specific therapy.1ReferencesLevine AM, Tulpule A.

34 SummaryAs patients live longer with HIV, morbidity and mortality from cancers are increasingThe types of cancers in HIV may vary in different populations around the worldTreatment of malignancies in HIV should be vigorous and appropriate to the situationSide effects of therapy should be treated/preventedPrevention strategies for virally-associated malignancies in HIV need to be investigatedThrough prospective clinical trials research can treatment and prevention strategies be effectively evaluatedSlide #44: SummaryAs patients live longer with HIV disease, we need to be alert to the development of cancers.Simultaneous treatment of HIV infection and cancer can make meaningful differences in patients’ lives.Treatment of side effects, including anemia, can make meaningful differences in patients’ quality of life.Groups like the AIDS Malignancy Consortium are working to sponsor and coordinate trials that can explore the best methods for treating these diseases and enabling patients to tolerate these treatments.Research contributes not only to improved treatment regimens but to our general understanding of the mechanisms of oncogenesis, viral proliferation, immune-system functions, and cell-cycle biochemistry.
