Impact of HIV status on prognosis of malignancies among people living with HIV in Japan.

Antiretroviral therapy has reduced the incidence and mortality of AIDS-defining malignancies (ADM); however, non-AIDS-defining malignancies (NADM) are a major cause of death among people living with HIV (PLWH) today. Though current guidelines suggest that PLWH should receive the same treatment as the general population, there are limited studies focused on how HIV status affects the prognosis of cancers. The present study aimed to investigate the characteristics and prognosis of malignant diseases among PLWH in Japan. Patients with HIV diagnosed with malignant diseases at our institution between 2011 and 2021 were retrospectively reviewed. There were 205 patients who were diagnosed with malignancies. Of these, 87 (42.4%) were diagnosed with ADM and 118 (57.6%) were diagnosed with NADM. Among 69 patients who received chemotherapy for ADM, 24 (34.8%) developed AIDS-defining opportunistic infections during treatment. In contrast, only one (1.8%) of the 56 patients administered chemotherapy for NADM developed AIDS-defining opportunistic infections. Complications of opportunistic infections at diagnosis of malignancies, low CD4+ T-cell count, positive HIV RNA, and nonadministration of antiretroviral therapy were associated with 5-year overall survival among patients with malignant lymphomas. However, the variables associated with HIV did not affect NADM prognosis. In this analysis, HIV status had a small impact on the prognosis of malignant diseases in PLWH. Few patients with NADM developed AIDS-defining opportunistic infections after receiving chemotherapy.

Measures of Longitudinal Immune Dysfunction and Risk of AIDS and Non-AIDS Defining Malignancies in Antiretroviral-Treated People With Human Immunodeficiency Virus.

Human immunodeficiency virus (HIV) infection leads to chronic immune activation/inflammation that can persist in virally suppressed persons on fully active antiretroviral therapy (ART) and increase risk of malignancies. The prognostic role of low CD4:CD8 ratio and elevated CD8 cell counts on the risk of cancer remains unclear. We investigated the association of CD4:CD8 ratio on the hazard of non-AIDS defining malignancy (NADM), AIDS-defining malignancy (ADM) and most frequent group of cancers in ART-treated people with HIV (PWH) with a CD4 and CD8 cell counts and viral load measurements at baseline. We developed Cox proportional hazard models with adjustment for known confounders of cancer risk and time-dependent cumulative and lagged exposures of CD4:CD8 ratio to account for time-evolving risk factors and avoid reverse causality. CD4:CD8 ratios below 0.5, compared to above 1.0, were independently associated with a 12-month time-lagged higher risk of ADM and infection-related malignancies (adjusted hazard ratio 2.61 [95% confidence interval {CI }1.10-6.19] and 2.03 [95% CI 1.24-3.33], respectively). CD4 cell counts below 350 cells/μL were associated with an increased risk of NADMs and ADMs, as did infection, smoking, and body mass index-related malignancies. In ART-treated PWH low CD4:CD8 ratios were associated with ADM and infection-related cancers independently from CD4 and CD8 cell counts and may alert clinicians for cancer screening and prevention of NADM.

Prognostic Factors in Children and Adolescents with Lymphomas and Vertical Transmission of HIV in Rio de Janeiro, Brazil: A Multicentric Hospital-Based Survival Analysis Study.

Lymphomas related to HIV are generally aggressive and have a poor prognosis, despite the use of combined antiretroviral therapy (cART) and effective chemotherapy treatment. To determine survival and prognostic factors in children and adolescents living with HIV (CLWH) in Rio de Janeiro (RJ), Brazil, who developed lymphomas, we performed a retrospective and observational study of vertically infected CLWH aged from 0 to 20 incomplete years during1995 to 2018 at five reference centers for cancer and HIV/AIDS treatment. Of the 25 lymphomas, 19 were AIDS-defining malignancies (ADM) and 6 were non-AIDS-defining malignancies (NADM). The 5-year overall survival (OS) and 5-year event-free survival (EFS) probabilities were both 32.00% (95% CI = 13.72-50.23%), and the 5-year disease-free survival (DFS) probability was 53.30% (95% CI = 28.02-78.58%). In the multivariate Cox regression analysis, performance status 4 (PS 4) was considered a poor prognostic factor for OS (HR 4.85, 95% CI = 1.81-12.97, p = 0.002) and EFS (HR 4.95, 95% CI = 1.84-13.34, p = 0.002). For the DFS, higher CD4+ T-cell counts were considered a better prognostic factor (HR 0.86, 95% CI = 0.76-0.97, p = 0.017) in the multivariate Cox regression analysis. This study demonstrates, for the first time, survival and prognostic factors for CLWH who developed lymphomas in RJ, Brazil.

Incidence and Clinical Description of Lymphomas in Children and Adolescents with Vertical Transmission of HIV in Rio de Janeiro, Brazil, in Pre- and Post-Combined Antiretroviral Therapy Eras: A Multicentric Hospital-Based Survival Analysis Study.

The incidence of cancer in children living with HIV (CLWH) is high and lymphomas are the most common type of cancer in this population. The combined antiretroviral therapy (cART) changed the natural history of HIV infection. To determine the incidence and profile of these CLWH malignancies in Rio de Janeiro (RJ), Brazil, we conducted a retrospective and observational study of vertically infected CLWH, ranging from 0-20 incomplete years, from 1995 to 2018, at five reference centers. The study period was divided into three eras in accordance with the widespread use of cART in Brazil. 1306 patients were included. Of the 25 lymphomas found, 19 were AIDS-defining malignancies (ADM); 6 were non-AIDS-defining malignancies (NADM). The incidence rate (IR) of lymphoma developing was 1.70 per 1000 children-year (95% CI 1.09-2.50). ADM development IR decreased from 2.09-1.75-0.19 per 1000 children-year (p < 0.001) through cART eras. Cumulative Nelson-Aalen hazards of developing ADM over a 20-year period were 3.73% in the Early-cART era, 3.07% in the Mid-cART era, and 0.32% in the Late-cART era (p = 0.013). This study demonstrates the IR of lymphoma in CLWH in RJ, Brazil, as well as the benefit of cART in reducing ADM and death occurrence in the Post-cART era.

A comparison of lung cancer in HIV-positive and HIV-negative populations.

Background Lung cancer is the most common cancer worldwide and is the greatest contributor to malignancy-associated deaths. Human immunodeficiency virus (HIV) is an epidemic in many developing countries and South Africa carries the largest burden of this disease in the world. With the introduction of antiretroviral therapy (ART), acquired immune deficiency syndrome (AIDS)-defining malignancies (ADMs) are on the decline and non-AIDS-defining malignancies (NADMs) are becoming more common, with lung cancer being the most common among these. Objectives To describe and compare a cohort of HIV-positive lung cancer patients and a cohort of HIV-negative lung cancer patients. Methods A retrospective study of 188 patients with histologically confirmed bronchogenic carcinoma was conducted. Smoking history, cancer sub-type, cancer stage, HIV parameters and demographic data were collected. Results There were 31 (16.94%) HIV-positive patients. They presented at a younger age (53.94 years) than the HIV-negative group (61.64 years) (p=0.0001). Adenocarcinoma was the most common sub-type in the HIV-negative cohort while squamous cell carcinoma was slightly more common in the HIV-positive cohort. Both groups predominantly presented with locally advanced or metastatic disease. Conclusion HIV-positive patients present at a younger age than HIV-negative patients and both groups show a male-predominant pattern.

Malignancies among children and young people with HIV in Western and Eastern Europe and Thailand.

Objectives:Investigate trends over time and predictors of malignancies among children and young people with HIV.Design:Pooled data from 17 cohorts in 15 countries across Europe and Thailand.Methods:Individuals diagnosed with HIV and presenting to paediatric care less than 18 years of age were included. Time at risk began at birth for children with documented vertically acquired HIV, and from first HIV-care visit for others. Children were followed until death, loss-to-follow-up, or last visit in paediatric or adult care (where data after transfer to adult care were available). Rates of reported malignancies were calculated overall and for AIDS-defining malignancies (ADM) and non-AIDS-defining malignancies (NADM) separately. Risk factors for any malignancy were explored using Poisson regression, and for mortality following a malignancy diagnosis using Cox regression.Results:Among 9632 individuals included, 140 (1.5%) were ever diagnosed with a malignancy, of which 112 (80%) were ADM. Overall, the rate of any malignancy was 1.18 per 1000 person-years; the rate of ADM decreased over time whereas the rate of NADM increased. Male sex, being from a European cohort, vertically acquired HIV, current severe immunosuppression, current viral load greater than 400 copies/ml, older age, and, for those not on treatment, earlier calendar year, were risk factors for a malignancy diagnosis. Fifty-eight (41%) individuals with a malignancy died, a median 2.4 months (IQR 0.6–8.8) after malignancy diagnosis.Conclusion:The rate of ADM has declined since widespread availability of combination ART, although of NADM, there was a small increase. Mortality following a malignancy was high, warranting further investigation.

Serious clinical events in HIV-positive persons with chronic kidney disease.

Predictors of chronic kidney disease (CKD) amongst HIV-positive persons are well established, but insights into the prognosis after CKD including the role of modifiable risk factors are limited. Prospective cohort study. D:A:D participants developing CKD (confirmed, >3 months apart, eGFR ≤ 60 ml/min per 1.73 m or 25% eGFR decrease when eGFR ≤ 60 ml/min per 1.73 m) were followed to incident serious clinical events (SCE); end stage renal and liver disease (ESRL and ESLD), cardiovascular disease (CVD), AIDS-defining and non-AIDS-defining malignancies (NADM), other AIDS or death, 6 months after last visit or 1 February 2016. Poisson regression models considered associations between SCE and modifiable risk factors. During 2.7 (IQR 1.1-5.1) years median follow-up 595 persons with CKD (24.1%) developed a SCE [incidence rate 68.9/1000 PYFU (95% confidence interval 63.4-74.4)] with 8.3% (6.9-9.0) estimated to experience any SCE at 1 year. The most common SCE was death (12.7%), followed by NADM (5.8%), CVD (5.6%), other AIDS (5.0%) and ESRD (2.9%). Crude SCE ratios were significantly higher in those with vs. without CKD, strongest for ESRD [65.9 (43.8-100.9)] and death [4.8 (4.3-5.3)]. Smoking was consistently associated with all CKD-related SCE. Diabetes predicted CVD, NADM and death, whereas dyslipidaemia was only significantly associated with CVD. Poor HIV-status predicted other AIDS and death, eGFR less than 30 ml/min per 1.73 m predicted CVD and death and low BMI predicted other AIDS and death. In an era where many HIV-positive persons require less monitoring because of efficient antiretroviral treatment, persons with CKD carry a high burden of SCE. Several potentially modifiable risk factors play a central role for CKD-related morbidity and mortality.

Non-AIDS-defining malignancies in Japanese hemophiliacs with HIV-1 infection.

Along improvement of prognosis of HIV-1-infected patients due to successful anti-retroviral therapy, main causes of death in the patients have been changing from AIDS to non-AIDS defining malignancies (NADM) recently. However, little is known about the prevalence and incidence of NADM in patients, and especially in HIV-1-infected hemophiliacs. We prospectively conducted NADM screening with FDG-PET, chest CT, upper gastrointestinal endoscopy, tumor markers, and stool occult blood in hemophiliacs with a mean age of 48.9 years. Screening was done twice from December 2016 through March 2019; the first screening was used to calculate prevalence in 69 patients and the second was used to calculate incidence in 56 patients. The first screening revealed 4 cases of malignancies; three were cases of thyroid cancer and one was a case of a neuroendocrine tumor in the pancreas; prevalence was 5.8% (95% CI: 0.2-11.4%). During a mean follow-up of 1.2 years with 68.2 person-years (PYs), cancer was diagnosed in 2 cases (pancreatic and liver cancer) during the second screening. Incidence was 2.99/100 PY. It can be speculated that there might be around 40 cases of undiagnosed NADM currently and 20 cases of new NADM annually in this population, because 718 HIV-1-infected hemophiliacs are surviving in Japan according to the 2018 Nationwide Survey on Coagulation Disorders. Screening for NADM in HIV-1-infected hemophiliacs at other hospitals is strongly recommended.

326. Is Antiretroviral Treatment Averting AIDS and non-AIDS Defining Malignancies in Colombia?

BackgroundThe use of effective antiretroviral therapy (ART) has shown to modify the trend of AIDS-defining malignancies (ADM) toward non-AIDS defining malignancies (NADM); however, Latin America is a region with a known late presentation of HIV/AIDS and late initiation of ART, which could not result in averting the incidence of ADM. The epidemiology of cancers that define or not AIDS in people living with HIV in Colombia is not known.MethodsThe purpose of our study was to identify the trend of ADM and NADM and the effect of ART in a collective cohort of 15 centers of 8 cities in Colombia. After the institutional review board approval, the study was conducted as a retrospective chart review of patients with any diagnosis of cancer presented after the diagnosis of HIV and a year before. Demographic and clinical data related to the HIV infection, ART treatment, and cancer diagnosis were analyzed with Stata 12 software, and associations between different variables were made using univariate and bivariate analyses.ResultsA total of 415 patients with malignancies were included since 1986 (table). Most common cancers were Kaposi sarcoma (n = 227; 54.7%), and non-Hodgkin lymphoma (n = 80, 19,3%). Median CD4+ cell count was very low in this population (median 115.5, P25-75 39.5–243) at the time of HIV diagnosis. Most common NADM were skin cancer (n = 22; 5.3%) and Hodgkin lymphoma (15; 3.6%). The ratio of ADM:NADM was 0.5 before 1995 and increased progressively up to 3.0 after 2010 (P = 0.001) (figure). By bivariate analysis, we found a correlation of ADM with older age (P < 0.001), male gender (P = 0.03), recent years (P < 0.001), lower CD4 and higher VL at the time of cancer (P < 0.0001 for both), and mortality (P = 0.027). Cancer-associated mortality was 3.9%.ConclusionThe trend for diagnosis of ADM in Colombia is increasing despite antiretroviral treatment and exceeds NADM diagnosis. Potential explaining factors are the late presentation and initiation of ART, and poor treatment success in this population. Special efforts are required to diagnose and treat HIV patients in Colombia to avert this worrying trend. Disclosures All authors: No reported disclosures.

Non-AIDS defining malignancies in the combination ART era: immunological and socio-behavioral risk factors

Background: Since the advent of combination antiretroviral therapy (cART), non-AIDS defining malignancies (NADM) have become increasingly important. We examined risk factors for NADM, including immunological, virological and socio-behavioral characteristics. Methods:We linked the Swiss HIV Cohort Study (SHCS) with cancer registries to identify incident cancers between 1996 and 2012. We analyzed four common NADM: anal, lung, prostate, and liver cancer. We calculated standardized incidence ratios (SIRs) and assessed the effect of time-updated CD4 and CD8 count, CD4/CD8 ratio, and HIV viral load (copies/ml) in Cox regression models. We lagged time-dependent variables for 12, 24, and 36 months and captured cumulative exposures using simple moving averages (SMA). In multivariable models, we also considered HIV transmission group, smoking, and chronic hepatitis B or C infection as potential predictors of NADM incidence.Results.Between 1996 and 2012, 563 HIV-infected individuals developed NADM, including 70 anal, 49 lung, 44 prostate, and 36 liver cancers. Compared with the general population, the SHCS exhibited higher rates of anal (SIR 76.1, 95% Confidence interval (CI) 60.2-96.2), lung (SIR 1.98, 1.50-2.62), and liver cancer (SIR 7.28, 5.25-10.1) but similar rates of prostate cancer (SIR 1.03, 0.76-1.38). Anal cancer was associated with low CD4 cell count, high CD8 cell count, men who have sex with men, and smoking. For lung cancer, the CD8 cell count was the only significant predictor identified among the immunological and virological factors. CD4 cell count, and chronic hepatitis B and C infection were predictive of liver cancer incidence. We found no evidence of any of the immunological factors being associated with prostate cancer.Conclusions:The importance of immunodeficiency (indexed by CD4 count) and immune senescence (indexed by CD8 count) differs across NADM. Immunodeficiency was an important risk factor for anal and liver cancer whereas immune senescence was associated with lung cancer and anal cancer.

Non-AIDS defining malignancies among HIV-infected patients in a tertiary referral center in Hong Kong.

1576Background: Non-AIDS defining malignancy (NADM) is increasingly recognized as an important cause of death among human immunodeficiency virus (HIV)-infected individuals. This study describes the details and survival trend of NADM in this group of patients in a tertiary center in Hong Kong. Methods: We have investigated the occurrence of NADM in a retrospective observational study of 1,523 HIV-infected patients. Baseline demographics, immunological data, the use of highly-active anti-retroviral therapy (HAART), details of malignancy and their treatment were analyzed. Survival was analyzed by Kaplan-Meier and Cox proportional hazards model. Results: From November 1993 to March 2013, a total of 41 NADM was diagnosed in 39 HIV-positive patients. Lung cancer, anogenital cancer, head and neck cancer, and hepatocellular carcinoma were the most common malignancies among the NADM. Compared with the 65 patients diagnosed with AIDS-defining malignancy (ADM), patients with NADM were significantly older at cancer d...

Overview of cancer incidence and mortality among people living with HIV/AIDS in British Columbia, Canada: Implications for HAART use and NADM development

BackgroundThe objective of this study is to evaluate the incidence of non-AIDS defining malignancies (NADMs) among people living with HIV/AIDS (PLWHA) in British Columbia, focusing on clinical correlates, highly active antiretroviral therapy (HAART) use, and survival, in order to elucidate mechanisms for NADM development.MethodsA retrospective population based analysis was carried out for individuals with HIV/AIDS that began their treatment between 1996 and 2008.ResultsThere were 145 (2.95%) NADMs and 123 (2.50%) AIDS defining malignancies (ADMs) identified in 4918 PLWHA in the study population. NADMs were represented by a range of cancer types including, most commonly, lung cancer, followed by anal, breast, head/neck, prostate, liver, rectal, and renal cancers. PLWHA had a SIR of 2.05 (CI:1.73, 2.41) for the development of NADMs compared to individuals without an HIV/AIDS diagnosis in the general population. Independent factors significantly associated with a NADM were: male gender, older age, lower CD4 cell counts, previous NADM, absence of HAART (non-HAART versus HAART) and treatment during the early-HAART era (before 2000 versus after 2000).ConclusionsNADMs represent an important source of morbidity for PLWHA. Use of HAART with its associated improvement in immune-restoration, and tailored targeted cancer screening interventions, may be beneficial and improve outcomes in this unique patient population.

Malignancies in women with HIV infection.

To review current knowledge of different cancer states affecting women with HIV infection. With improved survival of persons with HIV in the post-cART era, the landscape of malignancies in this population has greatly changed with fewer AIDS-defining malignancies (ADM) and a growing number of non-AIDS defining malignancies (NADM). Women, however, continue to represent a vulnerable population at risk for certain ADM and NADM such as cervical, anal, and breast cancer. Human papillomavirus-mediated cancers disproportionately burden women in resource-poor settings such as sub-Saharan Africa. For cancers such as Kaposi's sarcoma, lung cancer, liver cancer, and colorectal cancer, women share a lower burden of disease compared with their male counterparts. However, there remains a dearth of evidence characterizing these disease states specifically among women. Cancer in women with HIV continues to be a major source of morbidity and mortality worldwide, especially in low-income countries. Screening strategies, primary prevention through vaccination against human papillomavirus and viral hepatitis, and treatment for HIV with combined antiviral therapy remain cornerstones in cancer prevention.

High-density lipoprotein-cholesterol levels and risk of cancer in HIV-infected subjects: Data from the ICONA Foundation Cohort.

Investigation of the relationship between high-density lipoprotein-cholesterol (HDL-c) and the risk of developing cancer in a prospective cohort of human immunodeficiency virus (HIV)-infected patients.The Italian Cohort of Antiretroviral-naïve Patients Foundation Cohort is an Italian multicenter observational study recruiting HIV-positive patients while still antiretroviral treatment-naïve, regardless of the reason since 1997.Patients with at least 1 HDL-c value per year since enrollment and one such value before antiretroviral treatment initiation were included. HDL-c values were categorized as either low (<39 mg/dL in males or <49 mg/dL in females) or normal. Cancer diagnoses were classified as AIDS-defining malignancies (ADMs) or non-AIDS-defining malignancies (NADMs). Kaplan–Meier curves and Cox proportional-hazards regression models were used.Among 4897 patients (13,440 person-years of follow-up [PYFU]), 104 diagnoses of cancer were observed (56 ADMs, 48 NADMs) for an overall incidence rate of 7.7 (95% confidence interval [CI] 6.3–9.2) per 1000 PYFU.Low HDL-c values at enrollment were associated with higher risk both of cancer (crude hazard ratio [HR] 1.72, 95% CI 1.16–2.56, P = 0.007) and of NADM (crude HR 2.50, 95% CI 1.35–4.76, P = 0.003). Multivariate analysis showed that the risk of cancer diagnosis was higher in patients with low HDL-c values (adjusted HR [AHR] 1.87, 95% CI 1.18–2.95, P = 0.007) in older patients, those patients more recently enrolled, and in those with low current cluster of differentiation 4+ levels, and/or high current HIV-ribonucleic acid.The multivariate model confirmed an association between HDL-c (AHR 2.61, 95% CI 1.40–4.89, P = 0.003) and risk of NADM.Low HDL-c is an independent predictor of cancer in HIV-1-infected subjects.

The Role of Cancer Biomarkers in HIV Infected Hosts.

A higher incidence of cancer has been observed in Human Immunodeficiency Virus (HIV) infected individuals as compared with healthy people of the same age. A complex relationship between HIV-induced immune suppression, chronic antigenic stimulation, and oncogenic virus co-infections may promote carcinogenesis and increase the risk of developing tumors in these patients. Cancers in HIV subjects include the AIDS-defining malignancies (ADMs) and other non-AIDS-defining malignancies (NADMs). Antiretroviral therapy has reduced the incidence of ADMs whereas a concurrent increase of NADMs was observed in the last years. Biomarkers are measurable parameters, characterizing normal or pathogenic processes, which could provide a high potential for risk evaluation and diagnosis of patients. Therefore, the early detection of cancer biomarkers in HIV-positive subjects would be useful to identify patients at most risk of tumor disease development. This review will focus principally on the risk assessment and diagnostic role of several biomarkers of malignancy in HIV patients including cellular and viral biomarkers, cytokines, immune activation molecules and genetic polymorphisms.

The Spectrum of Malignancies among Adult HIV Cohort in Poland between 1995 and 2012: A Retrospective Analysis of 288 Cases.

The aim of the studyThe aim of the study was to evaluate the spectrum of AIDS-defining malignancies (ADMs) and non-AIDS-defining malignancies (NADMs) in HIV-infected patients in Poland.Material and methodsA retrospective observational study was conducted among HIV-infected adult patients who developed a malignancy between 1995 and 2012 in a Polish cohort. Malignancies were divided into ADMs and NADMs. Non-AIDS-defining malignancies were further categorised as virus-related (NADMs-VR) and unrelated (NADMs-VUR). Epidemiological data was analysed according to demographic data, medical history, and HIV-related information. Results were analysed by OR, EPITools package parameters and Fisher's exact test.ResultsIn this study 288 malignancies were discovered. The mean age at diagnosis was 41.25 years (IQR20-81); for ADMs 38.05 years, and for NADMs-VURs 46.42 years; 72.22% were male, 40.28% were co-infected with HCV. The risk behaviours were: 37.85% IDU, 33.33% MSM, and 24.31% heterosexual. Mean CD4+ at the diagnosis was 282 cells/mm3 (for ADMs 232 and for NADMs-VUR 395). Average duration of HIV infection at diagnosis was 5.69 years. There were 159 (55.2%) ADMs and 129 (44.8%) NADMs, among whom 58 (44.96%) NADMs-VR and 71 (55.04%) NADMs-VUR. The most frequent malignancies were: NHL (n = 76; 26.39%), KS (n = 49; 17.01%), ICC (n = 34; 11.81%), HD (n = 23; 7.99%), lung cancer (n = 18; 6.25%) and HCC (n = 14; 4.86%). The amount of NADMs, NADMs-VURs in particular, is increasing at present. Male gender (OR = 1.889; 95% CI: 1.104–3.233; p = 0.024), advanced age: 50–60 years (OR = 3.022; 95% CI: 1.359–6.720; p = 0.01) and ≥ 60 years (OR = 15.111; 95% CI: 3.122–73.151; p < 0.001), longer duration of HIV-infection and successful HAART (OR = 2.769; 95% CI: 1.675–4.577; p = 0) were independent predictors of NADMs overall, respectively.ConclusionsIn a Polish cohort NHL was the most frequent malignancy among ADMs, whereas HD was the most frequent among NADMs. Increased incidence of NADMs appearing in elderly men with longer duration of HIV-infection and with better virological and immunological control was confirmed. As HIV-infected individuals live longer, better screening strategies, especially for NADMs-VUR, are needed. The spectrum of cancer diagnoses in Poland currently does not appear dissimilar to that observed in other European populations.

Use of statins and risk of AIDS-defining and non-AIDS-defining malignancies among HIV-1 infected patients on antiretroviral therapy.

Previous studies have shown that statins use is associated with a lower mortality risk or occurrence of non-Hodgkin's lymphoma or non-AIDS-defining malignancies (NADMs) in HIV-positive patients. We evaluated the effect of statin therapy on the occurrence of all AIDS-defining malignancy (ADM) and NADM among HIV-positive patients. A chart study on HIV-1 infected patients attending the Infectious Diseases Department of the San Raffaele Scientific Institute, Italy. Incident malignancies diagnosed since antiretroviral treatment (ART) initiation until October 2012 among treated patients not taking statins at ART initiation. Statin therapy had to precede cancer diagnosis, if it occurred. Malignancies that occurred before ART or statin initiation were excluded. Follow-up was calculated since ART initiation until the first cancer diagnosis or loss to follow-up or death or last available visit, whichever occurred first. Results are described as median (interquartile range, IQR). Five thousand, three hundred and fifty-seven HIV-1 treated patients were included. During 52 663 person-years, 740 (14%) patients had a history of statin use; 375 malignancies occurred: 12 (1.6%) malignancies (0 ADM; 12 NADM, crude incidence rate, 1.3/1000 person-years) among statin users and 363 (7.9%) malignancies (194 ADM; 169 NADM, crude incidence rate, 8.4/1000 person-years) among non-statin users. By multivariate Fine-Gray regression, statin use was associated with a lower risk of cancer [adjusted hazard ratio (95% confidence interval) for ever use: 0.45 (0.17-0.71)]. Among HIV-1 treated patients, statin use was associated with a lower risk of cancer; the benefit was mainly related to AIDS-defining malignancies. Confirmatory studies are needed to consider the residual confounding likely present in this study.

Cumulative HIV viremia and non-AIDS-defining malignancies among a sample of HIV-infected male veterans.

Research suggests that cumulative measurement of HIV exposure is associated with mortality, AIDS, and AIDS-defining malignancies. However, the relationship between cumulative HIV and non-AIDS-defining malignancies (NADMs) remains unclear. The aim of this study was to evaluate the effect of different HIV measures on NADM hazard among HIV-infected male veterans. We performed a retrospective cohort study using Veterans Affairs HIV Clinical Case Registry data from 1985 to 2010. We analyzed the relationship between HIV exposure (recent HIV RNA, % undetectable HIV RNA, and HIV copy-years viremia) and NADM. To evaluate the effect of HIV, we calculated hazard ratios for 3 common virally associated NADM [ie, hepatocarcinoma (HCC), Hodgkin lymphoma (HL), and squamous cell carcinoma of the anus (SCCA)] in multivariable Cox regression models. Among 31,576 HIV-infected male veterans, 383 HCC, 211 HL, and 373 SCCA cases were identified. In multivariable regression models, cross-sectional HIV measurement was not associated with NADM. However, compared with <20% undetectable HIV, individuals with ≥80% had decreased HL [adjusted hazard ratio (aHR) = 0.62; 95% confidence interval (CI): 0.37 to 1.02] and SCCA (aHR = 0.64; 95% CI: 0.44 to 0.93). Conversely, each log10 increase in HIV copy-years was associated with elevated HL (aHR = 1.22; 95% CI: 1.06 to 1.40) and SCCA (aHR = 1.36; 95% CI: 1.21 to 1.52). Model fit was best with HIV copy-years. Cumulative HIV was not associated with HCC. Cumulative HIV was associated with certain virally associated NADM (ie, HL and SCCA), independent of measured covariates. Findings underline the importance of early treatment initiation and durable medication adherence to reduce cumulative HIV burden. Future research should prioritize how to best apply cumulative HIV measures in screening for these cancers.

Infecção VIH e Neoplasias Não Definidoras de SIDA: Experiência de um Centro

Human Immunodeficiency Virus infected patients have an increased risk for developing different types of cancer. After the introduction of highly active antiretroviral therapy (HAART), and consequent increased survival, a shift has been seen in the spectrum and evolution of HIV infection related diseases, particularly oncological ones, with a tendency to increase non-AIDS-defining malignancies (NADM) as opposed to AIDS defining malignancies. Characterization of the Human Immunodeficiency Virus infected patients with a non-AIDS defining malignancy diagnosis, followed over 16 years at an outpatient clinic in Lisbon through the review of medical records and retrospective evaluation of demographic, epidemiological, clinical and laboratorial parameters, treatment and mortality. Of the 1042 patients evaluated, there were 34 Non-AIDS defining malignancy cases identified, mostly in men (78%), with a median age of 55 years. The most common cancers were: lung (20.6%), bladder (17.6%), prostate (8.8%), and anal carcinoma (5.9%). The mean time between Human Immunodeficiency Virus infection and non-AIDS-defining malignancy diagnosis was 6.8 ± 4 years. At the time of non-AIDS- defining malignancy diagnosis the majority of patients (78.8%) was receiving HAART for a mean period of 5.7 ± 3 years, most of whom were immune and virologically controlled (64%). There were 45.5% deaths, mainly in patients with lung cancer (20%). Given the risk of developing a non-AIDS-defining malignancy in Human Immunodeficiency Virus-infected patients, it is essential to continue to invest in prevention strategies, promote smoking cessation as well as vaccination programs, as well as applying screening protocols adjusted to this population.
