Abstract
BACKGROUND Due to the prolonged life expectancy and increased risk of colorectal cancer (CRC) among patients with human immunodeficiency virus (HIV) infection, the prognosis and pathological features of CRC in HIV-positive patients require examination. AIM To compare the differences in oncological features, surgical safety, and prognosis between patients with and without HIV infection who have CRC at the same tumor stage and site. METHODS In this retrospective study, we collected data from HIV-positive and -negative patients who underwent radical resection for CRC. Using random stratified sampling, 24 HIV-positive and 363 HIV-negative patients with colorectal adenocarcinoma after radical resection were selected. Using propensity score matching, we selected 72 patients, matched 1:2 (HIV-positive:negative = 24:48). Differences in basic characteristics, HIV acquisition, perioperative serological indicators, surgical safety, oncological features, and long-term prognosis were compared between the two groups. RESULTS Fewer patients with HIV infection underwent chemotherapy compared to patients without. HIV-positive patients had fewer preoperative and postoperative leukocytes, fewer preoperative lymphocytes, lower carcinoembryonic antigen levels, more intraoperative blood loss, more metastatic lymph nodes, higher node stage, higher tumor node metastasis stage, shorter overall survival, and shorter progression-free survival compared to patients who were HIV-negative. CONCLUSION Compared with CRC patients who are HIV-negative, patients with HIV infection have more metastatic lymph nodes and worse long-term survival after surgery. Standard treatment options for HIV-positive patients with CRC should be explored.

Abstract
Viruses have the ability to modulate the cellular machinery of their host to ensure their survival. While humans encounter numerous viruses daily, only a select few can lead to disease progression. Some of these viruses can amplify cancer-related traits, particularly when coupled with factors like immunosuppression and co-carcinogens. The global burden of cancer development resulting from viral infections is approximately 12%, and it arises as an unfortunate consequence of persistent infections that cause chronic inflammation, genomic instability from viral genome integration, and dysregulation of tumor suppressor genes and host oncogenes involved in normal cell growth. This review provides an in-depth discussion of oncoviruses and their strategies for hijacking the host's cellular machinery to induce cancer. It delves into how viral oncogenes drive tumorigenesis by targeting key cell signaling pathways. Additionally, the review discusses current therapeutic approaches that have been approved or are undergoing clinical trials to combat malignancies induced by oncoviruses. Understanding the intricate interactions between viruses and host cells can lead to the development of more effective treatments for virus-induced cancers.

Abstract
Skin cancers represent the most common human tumors with a worldwide increasing incidence. They can be divided into melanoma and non-melanoma skin cancers (NMSCs). NMSCs include mainly squamous cell (SCC) and basal cell carcinoma (BCC) with the latest representing the 80% of the diagnosed NMSCs. The pathogenesis of NMSCs is clearly multifactorial. A growing body of literature underlies a crucial correlation between skin cancer, chronic inflammation and immunodeficiency. Intensity and duration of immunodeficiency plays an important role. In immunocompromised patients the incidence of more malignant forms or the development of multiple tumors seems to be higher than among immunocompetent patients. With regards to people living with HIV (PLWH), since the advent of combined antiretroviral therapy (cART), the incidence of non-AIDS-defining cancers (NADCs), such as NMSCs, have been increasing and now these neoplasms represent a leading cause of illness in this particular population. PLWH with NMSCs tend to be younger, to have a higher risk of local recurrence and to have an overall poorer outcome. NMSCs show an indolent clinical course if diagnosed and treated in an early stage. BCC rarely metastasizes, while SCC presents a 4% annual incidence of metastasis. Nevertheless, metastatic forms lead to poor patient outcome. NMSCs are often treated with full thickness treatments (surgical excision, Mohs micro-graphic surgery and radiotherapy) or superficial ablative techniques (such as cryotherapy, electrodesiccation and curettage). Advances in genetic landscape understanding of NMSCs have favored the establishment of novel therapeutic strategies. Concerning the therapeutic evaluation of PLWH, it’s mandatory to evaluate the risk of interactions between cART and other treatments, particularly antiblastic chemotherapy, targeted therapy and immunotherapy. Development of further treatment options for NMSCs in PLWH seems needed. We reviewed the literature after searching for clinical trials, case series, clinical cases and available databases in Embase and Pubmed. We review the incidence of NMSCs among PLWH, focusing our attention on any differences in clinicopathological features of BCC and SCC between PLWH and HIV negative persons, as well as on any differences in efficacy and safety of treatments and response to immunomodulators and finally on any differences in rates of metastatic disease and outcomes.

Trends in mortality among ART-treated HIV-infected adults in the Asia-Pacific region between 1999 and 2017: results from the TREAT Asia HIV Observational Database (TAHOD) and Australian HIV Observational Database (AHOD) of IeDEA Asia-Pacific. J Int AIDS Soc 2019; 22:e25219. [PMID: 30615271 PMCID: PMC6322485 DOI: 10.1002/jia2.25219] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Accepted: 11/05/2018] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION AIDS-related deaths in people living with HIV/AIDS have been decreasing in number since the introduction of combination antiretroviral treatment (cART). However, data on recent causes of death in the Asia-Pacific region are limited. Hence, we analysed and compared AIDS-related and non-AIDS-related mortality in high- and low-income settings in the region. METHODS Patients from the TREAT Asia HIV Observational Database (TAHOD) and Australian HIV Observational Database (AHOD) receiving cART between 1999 and 2017 were included. Causes of death verification were based on review of the standardized Cause of Death (CoDe) form designed by the D:A:D group. Cohorts were grouped as AHOD (all high-income sites), TAHOD-high (high/upper-middle income countries) and TAHOD-low (lower-middle income countries). TAHOD sites were split into high/upper-middle income and lower-middle income country settings based on World Bank classifications. Competing risk regression was used to analyse factors associated with AIDS and non-AIDS-related mortality. RESULTS Of 10,386 patients, 522 died; 187 from AIDS-related and 335 from non-AIDS-related causes. The overall incidence rate of deaths during follow-up was 0.28 per 100 person-years (/100 PYS) for AIDS and 0.51/100 PYS for non-AIDS. Analysis indicated that the incidence rate of non-AIDS mortality decreased from 0.78/100 PYS to 0.37/100 PYS from year groups 2003 to 2007 to 2013 to 2017 (p < 0.001). Similarly, incidence rates of AIDS-related deaths decreased from 0.51/100 PYS to 0.09/100 PYS from year groups 2003 to 2007 to 2013 to 2017 (p < 0.001). More recent years of follow-up were associated with reduced hazard for non-AIDS mortality (2008 to 2012: aSHR (adjusted sub-hazard ratio) 0.72, 95% confidence interval (CI) 0.54 to 0.96, p = 0.027; 2013 to 2017: aSHR 0.64, 95% CI 0.47 to 0.87, p = 0.004) compared to years 2003 to 2007. The AHOD cohort had almost twice the hazard of non-AIDS mortality compared to TAHOD-low (lower-middle income sites) (aSHR 1.72, 95% CI, 1.20 to 2.46, p = 0.003); there were no differences between cohorts for AIDS-related mortality (p = 0.834). CONCLUSION AIDS and non-AIDS-related mortality rates have decreased over the past years in the Asia-Pacific region. There is a greater risk for non-AIDS-associated deaths in the AHOD cohort compared to lower-middle income settings in TAHOD.

Abstract
Since their discovery as the etiologic agents of cervical cancer in the mid-1970s, human papillomaviruses (HPVs) have been linked with a growing number of epithelial-derived tumors, including head and neck squamous cell carcinomas. HPV demonstrates a particular predilection for causing tumors of the oropharynx, with the majority of cases involving infection with high-oncogenic risk HPV-16. People living with HIV are at increased risk of infection with HPV- and HPV-related oral complications even with adequate control of their HIV infection with antiretroviral therapy. In this chapter, we discuss the molecular mechanisms that underlie HPV-mediated oncogenesis in the oropharynx. We also describe the progress that has been made in understanding the epidemiology of oral HPV infection and the determinants of oral HPV-related pathology. Finally, we examine what can be done to treat and prevent oral HPV infection, benign lesions, and cancer, particularly in the context of the HIV-positive patient.

Abstract
Background Highly active antiretroviral therapy has significantly changed the natural history of HIV infection, leading to a dramatic reduction of HIV-related morbidity and mortality. Late Presenters, Very Late Presenters and AIDS presenters still represent, also in Europe, including Italy, a huge challenge in terms of diagnostic and therapeutic management. Case presentation A 35-year-old male with a history of fever and back pain. HIV test resulted positive with a high HIV Viral Load and a very low T-CD4 number of cells (5 cells/mm3). Imaging investigations revealed multiple vertebral and pulmonary lesions together with abdominal and thoracic lymphadenopathy. Blood cultures were positive for Cryptococcus neoformans and for Staphylococcus haemolyticus. Lymphnode biopsy resulted positive in PCR for Non-Tuberculosis Mycobacteria (Mycobacterium chelonae). A gastric biopsy also revealed a GIST. The patient also had CMV DNA positive. Although we performed antiretroviral therapy and specific-therapies for each disease, he was transferred to intensive care unit where he died due to an Acute Respiratory Distress Syndrome. Conclusion The reported case is unusual due to the relevant number of opportunistic diseases (both infectious and tumoral) emerging not long after the HIV infection had been diagnosed. Late presenters HIV patients and AIDS presenters still represent a challenge, which is often too complex for clinicians to deal with. In spite of proper management, the risk of suboptimal results cannot be excluded.

Abstract
Over the last 20 years we assisted to an increase in the mean age of People Living with HIV and their comorbidities. Especially, there was an increase in Human Papillomavirus-related head and neck squamous cell carcinomas. Despite their increasing incidence in HIV-positive people, mechanisms that lead to their development and progression are only partially understood. The aim of this review is to identify key data and factors about HPV-related head and neck squamous cell carcinoma in HIV-seropositive patients. Systematic search and review of the relevant literature-peer-reviewed and grey-was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. We included in our review only the 35 full-text articles we considered the most substantial. It is mandatory to improve our knowledge about the interactions existing between HPV and HIV, and about their actions on oral mucosa immune system.

Abstract
BACKGROUND Intracranial meningiomas are most common among patients in their fifth to seventh decade of life and rare in children and young adults. They constitute 1.5% of all neoplasms in patients age <20 years, but account for 13.5% of all neoplasms in patients age 20-34 years. They are often associated with hereditary or familial syndromes in children and young adults, and tend to be of high grade. Here we describe the histopathological subtypes of intracranial meningioma between human immunodeficiency virus 1 (HIV-1)-seropositive patients and the general population with intracranial meningiomas 35 years old and younger. METHODS Data were collected from all consecutive patients age ≤35 years diagnosed with intracranial meningioma between May 2003 and May 2015. Age was categorized as <20 years, 21-30 years, and >30 years. Histopathological grade was classified according to the 2000 World Health Organization (WHO) grading system as grade I, II, or III. Patients were grouped into an HIV-1-seropositive group and the general population, presumed seronegative. WHO grade II/III meningioma represented high-grade meningioma. RESULTS HIV-1-seropositive status was associated with increased risk of the development of high-grade (WHO grade II/III) meningioma (odds ratio, 2.9; 95% confidence interval, 1.06-8.09; P = 0.04) compared with the general population of patients with meningiomas. No significant associations were found between WHO grade and age, sex, ethnicity/race, or location. CONCLUSIONS Intracranial meningiomas in young HIV-1-positive patients tend to be of high grade; therefore, conservative or noninvasive therapies should be offered with caution and only after tissue diagnosis has confirmed benign WHO grade.

Abstract
AIDS-related cancer diseases are malignancies with low incidence on healthy people that affect mostly subjects already immunocompromised. The connection between HIV/AIDS and these cancers has not been established yet, but a weakened immune system is certainly the main cause. We envisaged the possibility to screen a small library of compounds synthesized in our laboratory against opportunistic tumors mainly due to HIV infection like Burkitt's Lymphoma. From cellular assays and gene expression analysis we identified two promising compounds. These derivatives have the dual action required inhibiting HIV replication in human TZM-bl cells infected with HIV-1 NL4.3 and showing cytotoxic activity on human colon HT-29 and breast adenocarcinoma MCF-7 cells. In addition, preclinical in vitro adsorption, distribution, metabolism, and excretion studies highlighted a satisfactory pharmacokinetic profile.

Abstract
INTRODUCTION The introduction of Highly Active Antiretroviral Therapy (HAART) into clinical practice has dramatically changed the outcome of HIV-infected patients by prolonging their survival. The increase in life expectancy has led to an increased risk of non-AIDS-related mortality and morbidity, including cardiovascular diseases, neurocognitive diseases, neuroendocrine dysfunctions and cancer. Areas covered: The GICAT (Italian Cooperation Group on AIDS and Tumors) has demonstrated that patients who receive a multidisciplinary approach with the combination of anticancer agents (AC) and HAART can achieve better responses and survival rates than patients who receive AC alone. The first obstacle for the oncologist to plan treatment for cancer HIV-patients is the preliminary evaluation of drug-drug interactions between AC and HAART. Recent progress in pharmacogenomics could provide a new approach for personalized treatments. The rationale of this review is to summarize the existing data on the impact of HAART on the clinical management of cancer patients with HIV/AIDS and DDIs between antiretrovirals and AC. In addition, to maximize the efficacy of both concomitant therapy and to minimize the risk of DDIs, a currently useful list of pharmacogenomic markers of key metabolic enzymes is provided. Expert opinion: In this scenario, the importance of cooperation between oncologists and other health specialists (i.e., infectivologists, pharmacists, genetics and lab specialists) must not be underestimated in the management of these patients with the aim of planning an individual treatment strategy.

Abstract
Many HIV-infected individuals do not enter health care until late in the infection course. Despite encouraging earlier testing, this situation has continued for several years. We investigated the prevalence of late presenters and factors associated with late presentation among HIV-infected patients in an Asian regional cohort. This cohort study included HIV-infected patients with their first positive HIV test during 2003-2012 and CD4 count and clinical status data within 3 months of that test. Factors associated with late presentation into care (CD4 count <200 cells/μl or an AIDS-defining event within ±3 months of first positive HIV test) were analyzed in a random effects logistic regression model. Among 3,744 patients, 2,681 (72%) were late presenters. In the multivariable model, older patients were more likely to be late presenters than younger (≤30 years) patients [31-40, 41-50, and ≥51 years: odds ratio (OR) = 1.57, 95% confidence interval (CI) 1.31-1.88; OR = 2.01, 95% CI 1.58-2.56; and OR = 1.69, 95% CI 1.23-2.31, respectively; all p ≤ 0.001]. Injecting drug users (IDU) were more likely (OR = 2.15, 95% CI 1.42-3.27, p < 0.001) and those with homosexual HIV exposure were less likely (OR = 0.45, 95% CI 0.35-0.58, p < 0.001) to be late presenters compared to those with heterosexual HIV exposure. Females were less likely to be late presenters (OR = 0.44, 95% CI 0.36-0.53, p < 0.001). The year of first positive HIV test was not associated with late presentation. Efforts to reduce the patients who first seek HIV care at the late stage are needed. The identified risk factors associated with late presentation should be utilized in formulating targeted public health intervention to improve earlier entry into HIV care.

Kaposi's sarcoma-associated herpesvirus-encoded LANA associates with glucocorticoid receptor and enhances its transcriptional activities. Biochem Biophys Res Commun 2015; 463:395-400.

Abstract
Kaposi's sarcoma-associated herpesvirus (KSHV)-encoded latency-associated nuclear antigen (LANA), which interacts with cellular proteins, plays a central role in modification of viral and/or cellular gene expression. Here, we show that LANA associates with glucocorticoid receptor (GR), and that LANA enhances the transcriptional activity of GR. Co-immunoprecipitation revealed a physical interaction between LANA and GR in transiently transfected 293T and HeLa cells. In human B-lymphoma cells, LANA overexpression enhanced GR activity and cell growth suppression following glucocorticoid stimulation. Furthermore, confocal microscopy showed that activated GR was bound to LANA and accumulated in the nucleus, leading to an increase in binding of activated GR to the glucocorticoid response element of target genes. Taken together, KSHV-derived LANA acts as a transcriptional co-activator of GR. Our results might suggest a careful use of glucocorticoids in the treatment of patients with KSHV-related malignancies such as Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman disease.

Abstract
We retrospectively compared the incidence of neutropenia in two groups of HIV patients with lymphoma, who underwent chemotherapy supported by once-per-cycle administration of pegfilgrastim or by daily subcutaneous injection of filgrastim, respectively. Our findings indicate that pegfilgrastim and filgastrim produce similar results in preventing both neutropenia and febrile neutropenia.

Abstract
OBJECTIVES Pancreatic cancer (PC) is the fourth and fifth most common cause of cancer-related death among men in United States and in Europe, respectively. No data are available for HIV-positive patients. The aim of this study was to investigate and to compare clinical presentation and outcome between HIV-positive and HIV-negative PC patients. METHODS From April 1988 to June 2010, the Italian Cooperative Group on AIDS and Tumors identified 16 cases of HIV-positive PC patients. Each HIV-positive patient from our institution was randomly matched (ratio 1:2) with HIV-negative patients (32 controls) based on sex and year of PC diagnosis. Differences in clinical presentation, treatment, and overall survival were assessed. RESULTS At multivariate analysis, HIV-positive patients compared with HIV-negative patients had a higher risk of an unfavorable performance status (PS ≥ 2) and a younger age (<50 years) at cancer diagnosis. At multivariate analysis, HIV-positive status and PS of 2 or greater were the only 2 features that significantly reduced PC patients' survival. CONCLUSIONS Our data show, for the first time, that HIV-positive PC patients, compared with HIV-negative patients, are younger at cancer diagnosis. Furthermore, they share a more unfavorable PS and a shorter survival.

Abstract
PURPOSE: To morphometrically quantify CD1a+ dentritic cells and DC-SIGN+ dendritic cells in HIV-positive patients with anal squamous intraepithelial neoplasia and to evaluate the effects of HIV infection, antiretroviral therapy and HPV infection on epithelial and subepithelial dendritic cells. METHODS: A prospective study was performed to morphometrically analyze the relative volume of the dendritic cells and the relationship between anal intraepithelial neoplasia and cancer in HIV-positive patients from the Tropical Medicine Foundation of Amazonas, Brazil. All patients were submitted to biopsies of anorectal mucosa to perform a classic histopathological and immunohistochemical analysis, employing antibodies against CD1a and DC-SIGN for the morphometric quantification of dendritic cells. RESULTS: HIV-negative patients displayed a CD1a DC density significantly higher than that of HIV-positives patients (3.75 versus 2.54) (p=0.018), and in patients with severe anal intraepithelial neoplasia had correlated between DC CD1a density with levels of CD4 + cells (p: 0.04) as well as the viral load of HIV-1 (p: 0.035). A not significant rise in the median density of CD1a+ DC was observed in the HIV positive/ HAART positive subgroup compared to the HIV positive/ HAART negative subgroup. The CD1a+ DC were also significantly increased in HIV-negative patients with anorectal condyloma (2.33 to 3.53; p=0.05), with an opposite effect in HIV-positive patients. CONCLUSIONS: Our data support an enhancement of the synergistic action caused by HIV-HPV co-infection on the anal epithelium, weakening the DC for its major role in immune surveillance. Notoriously in patients with severe anal intraepithelial neoplasia, the density of CD1a+ epithelial dendritic cells was influenced by the viral load of HIV-1. Our study describes for the first time the density of subepithelial DC-SIGN+ dendritic cells in patients with anal severe anal intraepithelial neoplasia and points to the possibility that a specific therapy for HIV induces the recovery of the density of epithelial DC.

Abstract
BACKGROUND a clinical study of 14 patients presenting both malignant melanoma and HIV infection, and analysis of the literature to determine the frequency and specific features of this association. PATIENTS AND METHODS ten men and four women of median age 43 years were included. In 50% of cases, the primary melanoma consisted of spreading superficial melanoma with a mean Breslow thickness of 2.83 mm. In two cases, regional lymph node metastasis was discovered but with no primary melanoma being identified. HIV infection was already documented on diagnosis of melanoma in 11 cases, and it was discovered in three cases at the time of surgery for melanoma (treatment of the primary melanoma in two cases, and in one case, regional lymph node dissection two years after the initial diagnosis). Eight patients died within a mean period of 39 months, with melanoma being the cause of death in six cases. Following relapse of melanoma, the course of the disease was severe, with mean stage IV survival of 3.6 months. No response to chemotherapy was observed where such treatment was feasible. DISCUSSION the presence of HIV appears to be an aggravating factor for the outcome of metastatic melanoma. CONCLUSION our study suggests the importance of clinical examination of pigmented lesions in HIV patients in order to ensure early identification of melanoma.

Abstract
BACKGROUND Previous studies suggest a poor prognosis of epidermoid anal cancer in HIV+ patients. AIM To investigate the long-term outcome of epidermoid anal cancer in HIV+ and HIV- patients in the highly active antiretroviral treatment (HAART) era. METHODS We included all patients with epidermoid anal cancer referred to six hospitals from 1998 to 2004. RESULTS In all, 151 patients (44 HIV+, 107 HIV-) were reviewed retrospectively for 27 (median of 16-44) months. HIV+ patients were male (100% vs. 27%, P < 0.001) and younger (45 vs. 62 years old, P < 0.001) than HIV- patients. No significant differences were observed in the tumour stage, pelvic radiotherapy dose or concomitant chemotherapy, according to the HIV status. After chemoradiotherapy, similar numbers of HIV+ and HIV- patients had grade III-IV toxicity. A complete response was obtained in 82% and 75% (N.S.) of cases, respectively. The disease-free survival rates were 77% and 67% (N.S.) and the overall survival rates were 85% and 84% (N.S.), respectively, after 3 years of follow-up. Duration of HIV infection, viral load and CD4 count had no effect on the survival rate of HIV+ patients with EAC. CONCLUSIONS The clinical outcome of HIV+ patients with epidermoid anal cancer is similar to that of HIV- patients. Therefore, the same therapeutic guidelines should be applied to both populations.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection is known to be associated with an increased risk of non-Hodgkin's lymphoma (NHL). The majority of lymphomas (>80%) occurring during immunosuppression are aggressive B-cell in origin and have a high-to-intermediate histology grade. Treatment of NHL is not standardized. OBJECTIVES To assess the clinical effectiveness and safety of single agent or combination chemotherapy with or without immunochemotherapy (rituximab) and with or without highly active antiretroviral therapy (HAART) on overall survival (OS) and disease-free survival (DFS) for previously untreated patients with AIDS-related NHL. SEARCH STRATEGY The Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2009), MEDLINE (1966-March 6, 2009), EMBASE (1988-March 6, 2009), LlLACS (1982 to February 17, 2009), Gateway (March 6, 2009), and AIDSearch (2006 -February 2008) were used to identify published, potentially eligible trials. Further, we searched several electronic sources. For additional information see the Cochrane HIV/AIDS Group search strategy. SELECTION CRITERIA Randomized controlled trials (RCTs) assessing the effectiveness of systemic treatments for previously untreated AIDS-related NHL. There were no age or language restrictions. DATA COLLECTION AND ANALYSIS Authors independently assessed relevant studies for inclusion; four RCTs were selected. No meta-analysis was attempted due to clinical heterogeneity. MAIN RESULTS Four RCTs that included 857 patients (number range: 30 to 485) met the inclusion criteria. The studies have a high risk of bias; three RCTs were conducted in the United States and one was a multi-national, multi-centre RCT performed in France and Italy. One of the trials included only men. It was impossible to pool data for any of the outcomes due to the differences in the interventions assessed in these RCTs. Overall survival did not differ significantly between treatment groups. Disease free survival (DFS) was reported in two of the four RCTs, but it was not statistically significant between treatment groups. AUTHORS' CONCLUSIONS We found no evidence that the systemic interventions for untreated patients with AIDS-related NHL provide superior clinical effectiveness for improving OS, DSF, and tumour response rate; however, this conclusion is based on four RCTs with limited sample size and variable quality. More adequately powered RCTs that have low risk of bias are necessary to determine the real benefit or harm of interventions to treat this population. Overall survival (OS), DFS, and quality of life should be included as endpoints.

Abstract
Oral lesions are among the early signs of HIV infection and can predict its progression to acquired immunodeficiency syndrome (AIDS). A better understanding of the oral manifestations of AIDS in both adults and children has implications for all health care professionals. The knowledge of such alterations would allow for early recognition of HIV-infected patients. The present paper reviews epidemiology, relevant aspects of HIV infection related to the mouth in both adults and children, as well as current trends in antiretroviral therapy and its connection with orofacial manifestations related to AIDS.

Abstract
PURPOSE Highly active antiretroviral therapy has enabled better control over HIV infection. Thus, the immunologic status of such patients has been improving and we believe that changes in their perianal diseases also have been occurring. This study was designed to compare anorectal disease incidence among HIV-positive patients attended in two eras: prehighly active antiretroviral therapy and highly active antiretroviral therapy. METHODS We examined 5,660 HIV-positive patients with anorectal diseases, divided into two groups: 1,860 treated during 1989 to 1995 (Group 1), and 3,800 during 1996 to 2005 (Group 2). RESULTS In Group 1, the most common diseases were condylomas (24.7 percent), ulcers (21.8 percent), and anal fistulas (19.7 percent). Tumors occurred in 2.5 percent, with Kaposi's sarcoma in 51.1 percent, and squamous-cell carcinoma in 27.6 percent. In Group 2, the most common anorectal lesions were condylomas (75.6 percent), ulcers (17 percent), and fistulas (12.1 percent). The tumor incidence was 1.8 percent, with squamous-cell carcinoma in 59.4 percent and Kaposi's sarcoma in 23.2 percent. Changes in incidence were statistically significant for the increase in condylomas and fissures, and for the decrease in ulcers, fistulas, and Kaposi's sarcoma among Group 2 patients. CONCLUSION Anorectal disease incidences have changed in the highly active anti-retroviral therapy era.

Abstract
HIV-infected patients face a greater risk of developing malignant disease. The most commonly reported neoplasms of the head and neck region include Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL). There is also an increased risk of oral squamous cell carcinoma (SCC). A descriptive cross-sectional study including HIV-infected patients with neoplastic and non-neoplastic lesions was conducted. Of the 200 participants, 116 (58%) were male and 84 (42%) female with an age range of 18-61 years (mean 37 years). The females were significantly younger (mean 33 years) than the males (mean 37 years) (t test; 2.57; P<0.05 [0.001]). The prevalence of neoplastic lesions in this study was 27%; 37 (68%) patients had KS, 9 (17%) had SCC, 7 (13%) had NHL and 1 (2%) had Burkitt's lymphoma. More females than males presented with lesions of KS and SCC compared with NHL. The youngest patient presented with SCC at 18 years (mean 35.7 years), followed by KS at 23 years (mean 36.3 years) and NHL at 33 years (mean 43.9 years). Most study participants (97%) were in stage III/IV of the disease and the remaining 3% in stage II. In this study, the most common malignant neoplasms were KS, SCC and NHL, manifesting in a younger age group than in the non-HIV group of patients.

Abstract
Colorectal cancers are rare in developing countries, but are the second most frequent malignancy in the affluent world. Data on colorectal cancer in HIV-positive patients are limited. Up to now, there are no published data on treatment patterns, response to therapy, or survival in this setting. Oxaliplatin is an antineoplastic agent currently indicated, concomitantly to fluorouracil and leucovorin, for the treatment of advanced colorectal cancer. The FOLFOX-4 regimen (oxaliplatin 85 mg/m(2) as a two-hour infusion on day 1; leucovorin 200 mg/m(2) as a two-hour infusion on days 1 and 2, fluorouracil as a bolus infusion on days 1 and 2, followed by a fluorouracil 22-hour infusion 600 mg/m(2) for two consecutive days every two weeks), with concomitant highly active antiretroviral therapy (HAART) is feasible and active, while the HIV infection is not a limiting factor for its use. Moreover, the concomitant use of HAART does not seem to increase the toxicity of the FOLFOX-4 regimen.

BACKGROUND Plasmablastic lymphoma (PBL) is an unusual non-Hodgkin lymphoma (NHL) most commonly found in the head and neck region. The majority of cases are seen in adult HIV-positive patients, although PBL has been reported in HIV-negative patients. The diagnosis of PBL serves as an AIDS-defining illness. METHODS We report a case of PBL localized to the oral cavity in a previously undiagnosed AIDS patient. The lesion manifested as solitary, ulcerated, and markedly tender. PBL was confirmed by immunohistochemical profile and subsequent tests confirmed AIDS diagnosis. The patient was prescribed highly active antiretroviral therapy (HAART) and concomitant local low dose radiation therapy prior to initiation of chemotherapy. RESULTS Complete local clinical response was observed after 4 weeks of treatment with HAART and radiation therapy. The response sustained in this patient in the subsequent 11 months following diagnosis. CONCLUSIONS The diagnosis of PBL has a unique immunophenotypic profile and should raise suspicion for AIDS in these patients. HAART added to treatment has shown improved survival.

Abstract
BACKGROUND Hodgkin's disease (HD) is the most common non-AIDS-defining malignancy in HIV-infected patients. Its unusually aggressive tumour behaviour includes a higher frequency of unfavourable histologic subtypes, high-stage and extranodal involvement by the time of presentation (anal canal, stomach), and poor therapeutic outcome, in comparison with HD outside the HIV setting. The optimal therapeutic strategy is still controversial, and median overall survival is short, ranging from 12 to 18 months. Thus, there is a need to identify the efficacy and safety of different interventions for AIDS-associated HD on overall survival and disease-free survival in treatment-naive adults with AIDS. OBJECTIVES To assess the effects of different interventions for treating AIDS-associated Hodgkin's disease including chemotherapy, bone marrow transplantation (BMT), and gene therapy on overall survival and disease-free survival in treatment-naive adults with AIDS. SEARCH STRATEGY We searched The Cochrane HIV/AIDS Group Trials Register (September 2006), which comprises references identified from comprehensive electronic database searches and handsearching of relevant journals and abstract books of conference proceedings. We also searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 3, 2006), MEDLINE (1966 to September 2006), EMBASE (1974 to September 2006) LILACS (1982 to September 2006), ISI Web of Knowledge (1993 to September 2006), and AIDSearch (1980 to December 2006). Date of most recent search: December 2006. SELECTION CRITERIA We searched for published or unpublished randomised controlled trials. DATA COLLECTION AND ANALYSIS We intended to summarise data by standard Cochrane Collaboration methodologies, but no eligible randomised controlled trials were identified. MAIN RESULTS We were unable to find any randomised controlled trials of interventions for treating AIDS-associated HD in treatment-naive adults with AIDS. AUTHORS' CONCLUSIONS Randomised controlled trials are needed to establish the efficacy and safety of interventions for treating AIDS-associated HD in treatment-naive adults with AIDS.

Abstract
Among individuals with HIV-infection, coinfection with oncogenic viruses including EBV, HHV-8, and HPV cause significant cancer-related morbidity and mortality. It is clear that these viruses interact with HIV in unique ways that predispose HIV-infected individuals to malignant diseases. In general, treatment directed specifically against these viruses does not appear to change the natural history of the malignant disease, and once the malignancy develops, if their health permits, HIV-infected patients should be treated using similar treatment protocols to HIV-negative patients. However, for the less frequent HIV-related malignancies, such as PEL, or MCD, optimal treatments are still emerging. For certain AIDS-defining malignancies, it is clear that the widespread access to HAART has significantly decreased the incidence, and improved outcomes. However, for other cancers, such as the HPV-related tumors, the role of HAART is much less clear. Further research into prevention and treatment of these oncogenic virally mediated AIDS-related malignancies is necessary.

Abstract
HPV infection of both the genital tract and oral cavity of HIV+ men and women is increased. HPV-related pathology is also increased in the HIV+ individuals, usually with further increases seen for those HIV+ individuals with lower CD4 cell counts. Fortunately, the rates of cervical cancer and anal cancer are relatively low and not related to CD4 cell count. Treatment of the HIV+ individual with HPV-related disease is challenging and requires close long-term follow-up to prevent recurrent disease. The mechanism of how HPV and HIV interact is still not known but is more likely to be linked to immune suppression rather than a direct interaction between viruses. The newly developed HPV vaccines will likely have a significant impact on HPV-related disease in immunocompetent individuals. It remains to be seen what impact these vaccine will have on the immune depressed.

Abstract
Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) pose major public health concerns worldwide. HCV is clearly associated with the occurrence of hepatocellular carcinoma, and recently HIV infection has also been linked to the development of a multitude of cancers. Previously, we identified a novel nucleoside analog transcriptional inhibitor ARC (4-amino-6-hydrazino-7-beta-D-ribofuranosyl-7H-pyrrolo[2,3-d]-pyrimidine-5-carboxamide) that exhibited proapoptotic and antiangiogenic properties in vitro. Here, we evaluated the effect of ARC on HIV-1 transcription and HCV replication. Using reporter assays, we found that ARC inhibited HIV-1 Tat-based transactivation in different cell systems. Also, using hepatoma cells that harbor subgenomic and full-length replicons of HCV, we found that ARC inhibited HCV replication. Together, our data indicate that ARC could be a promising candidate for the development of antiviral therapeutics against HIV and HCV.

Abstract
PURPOSE To evaluate in a pilot study the safety and efficacy of liposomal doxorubicin, cyclophosphamide, and etoposide (LACE) when combined with antiretroviral therapy (ART) in patients with AIDS-related lymphoma (ARL). The impact of HIV viral control on therapy and survival was also assessed. PATIENTS AND METHODS Between 1994 and 2005, 40 patients at Virginia Mason Medical Center were diagnosed with ARL. Twelve received LACE every 28 days. All patients received intrathecal chemoprophylaxis, ART, and G-CSF. RESULTS The median patient CD4+ count was 190 cells/microl (range, 20-510 cells/microl), and the median HIV viral load (VL) was 61,613 copies/ml (range, <50-500,000 copies/ml). Seven patients (58%) had an International Prognostic Index score of 3 or 4. Six patients (50%) were ART-naïve, five were viremic despite ART, and one had an undetectable HIV-1 VL. Nine patients (75%) achieved a complete response (CR), and median overall survival was 107 months. At a median follow-up of 46 months, the recurrence-free survival rate was 50%. Two patients died from relapsed/refractory ARL and one patient achieved a CR with salvage therapy. One CR patient died from complications of pneumonia, and another CR patient died from uncertain causes 5 years after treatment. Grade 3 or 4 neutropenia occurred in 23 of 61 (38%) chemotherapy cycles. Hospitalization was required after 5% of treatment cycles due to neutropenic fever. CONCLUSION LACE is an effective and tolerable treatment for ARL. HIV viral control can be maintained in the majority of patients during and after completion of LACE.

Abstract
A radioquimioterapia (RT/QT) tornou-se o tratamento de escolha para o carcinoma espinocelular anal (CEC). Na recidiva local ou na persistência da doença, deve-se instituir o tratamento cirúrgico. OBJETIVO: O objetivo deste estudo retrospectivo foi analisar os resultados do tratamento de doentes de CEC anal. MÉTODO: Acompanhamos 17 pacientes com diagnóstico anátomo-patológico de carcinoma espinocelular anal. Eram 14 (82,3%) do sexo feminino e três (17,8%) do masculino. A idade variou de 36 a 78 anos, com média de idade de 59,1 anos. Utilizando a classificação TNM, tivemos quatro (23,6%) no estádio I, seis (35,2%) no II, quatro (23,6%) no IIIa e três (17,6%) no IIIb. Todos foram submetidos a tratamento inicial com RT/QT, exceto um submetido a ressecção local. Definimos que a biópsia negativa, realizada entre 12 e 16 semanas após esse tratamento, determinaria o controle local da doença. RESULTADOS: Perdemos seguimento de três doentes (17,6%). Seguimos os 14 restantes (82,3%) entre um e cinco anos. Todos os doentes nos estádios I e II (10) apresentaram regressão total da doença, enquanto que três (75%) nos estádios IIIa e IIIb tiveram remissão completa. Realizamos a amputação abdomino-perineal de resgate em dois doentes e ressecção local em outros dois. A recidiva local ocorreu em dois (20%) nos estádios I e II e em dois (75%) nos estádios mais avançados (IIIa e IIIb). A sobrevivência em 3 anos foi de 100% nos que se encontravam nos estádios I e II, embora o controle da doença fosse atingido em oito (80%). Nos quatro doentes que estavam nos estádios IIIa e IIIb, a sobrevivência em um ano foi de 75% e em três anos foi de 25%. Esse último permanece livre da doença. Complicações do tratamento radioterápico ocorreram em oito doentes (57,1%). Nenhum óbito foi constatado durante o tratamento RT/QT. Os dois doentes, (14,3%) com sorologia positiva para HIV, apresentavam infecção anal pelo Papilomavírus humano (HPV). CONCLUSÃO: A análise dos nossos resultados evidenciou que o esquema de tratamento empregado foi efetivo para o controle local e preservação da função esfincteriana do ânus e que, na falha do tratamento radioquimioterápico, a operação de resgate controlou localmente a doença.

Abstract
Infection with human immunodeficiency virus (HIV) and progression to acquired immune deficiency syndrome (AIDS) are associated with a vide variety of morbidities. Local and systemic diseases can develop in association with HIV infection and may manifest themselves as malignancies of the oropharynx. Advances in HIV management, fueled by increasing understanding of molecular pathogenesis, have resulted in marked changes in the prevalence of oral malignant disease. This paper discusses recent trends in the presentation and treatment of malignancies related to HIV and AIDS with an emphasis on malignancies seen in the oral cavity.

Abstract
HIV infection affects residents of all countries of the world, but the greater majority of affected individuals reside in the developing world. In the past decade there have been substantial changes in the management of HIV disease, particularly the introduction of highly active antiretroviral therapy (HAART). Such agents have reduced significantly the morbidity and mortality associated with HIV disease, however, they are not available for most HIV-infected individuals in the developing world. There is now considerable understanding of the molecular epidemiology, transmission and therapy of the common opportunistic oral infections of HIV disease, and as a consequence of improved anti-HIV strategies, the frequency and severity of oral disease associated with HIV infection have reduced considerably, although HAART may predispose to human papilloma virus infection of the mouth and potentially increase the risk of later oral squamous cell carcinoma. Despite advances in clinical care the majority of individuals with HIV disease worldwide will continue to develop oral disease, as they are resident in the developing world and do not have ready access to even simple therapies.
