Lung cancer (LC) screening detects tumors early. The prospective GESIDA 8815 study was designed to assess the usefulness of this strategy in HIV + people (PLHIV) by performing a low-radiation computed tomography (CT) scan.

371 heavy smokers patients were included (>20 packs/year), >45 years old and with a CD4+ <200 mm3 nadir. One visit and CT scan were performed at baseline and 4 for follow-up time annually.

329 patients underwent the baseline visit and CT (CT0) and 206 completed the study (CT1 = 285; CT2 = 259; CT3 = 232; CT4 = 206). All were receiving ART. A total >8 mm lung nodules were detected, and 9 early-stage PCs were diagnosed (4 on CT1, 2 on CT2, 1 on CT3 and 2 on CT4). There were no differences between those who developed LC and those who did not in sex, age, CD4+ nadir, previous lung disease, family history, or amount of packets/year. At each visit, other pathologies were diagnosed, mainly COPD, calcified coronary artery and residual tuberculosis lesions. At the end of the study, 38 patients quit smoking and 75 reduced their consumption. Two patients died from LC and 16 from other causes (p = 0.025).

The design of the present study did not allow us to define the real usefulness of the strategy. Adherence to the test progressively decreased over time. The diagnosis of other thoracic pathologies is very frequent. Including smokers in an early diagnosis protocol for LC could help to quit smoking.

Non-AIDS defining malignancies present a growing challenge for persons with human immunodeficiency virus (HIV, PWH), yet tailored interventions for timely cancer diagnosis are lacking. The Spanish IMPAC-Neo protocol was designed to compare two comprehensive cancer screening strategies integrated into routine HIV care. This study reports baseline data on the prevalence and types of precancerous lesions and early-stage cancer among participants at enrolment. Acceptability of the procedure was additionally assessed.

Cross-sectional analysis of a comprehensive screening protocol to detect precancer and cancer. The readiness of healthcare providers to implement the protocol was evaluated using a validated 4-item survey.

Among the 1430 enrolled PWH, 1172 underwent 3181 screening tests, with positive findings in 29.4% of cases, leading to further investigation in 20.7%. Adherence to the protocol was 84%, with HIV providers expressing high acceptability (97.1%), appropriateness (91.4%), and feasibility (77.1%). A total of 145 lesions were identified in 109 participants, including 60 precancerous lesions in 35 patients (3.0%), 9 early-stage cancers in 9 patients (0.8%), and 76 low-risk lesions in 65 subjects (5.5%). Adverse events related to screening occurred in 0.8% of participants, all mild. The overall prevalence of cancer precursors or early-stage cancer was 3.8% (95% confidence interval [CI], 2.74%-5.01%), with highest rates observed in individuals screened for anal and colorectal cancers.

The baseline comprehensive cancer screening protocol of the IMPAC-Neo study successfully identified a significant proportion of PWH with precancerous lesions and early-stage cancer. High adherence rates and positive feedback from providers suggest effective implementation potential in real-world healthcare settings.

Cancer is the leading cause of mortality in people living with HIV (PWH) and is expected to account for a growing fraction of deaths as PWH age.

In this literature review, we have compiled the most recent developments in cancer screening and screening performance in PWH, which are currently primarily implemented in well-resourced settings. This includes an assessment of the associated benefits, harms, and cost-effectiveness. The article also addresses unmet needs and potential strategies for tailored screening in the HIV population.

Incidence and mortality due to screenable cancer are higher in PWH than in the general population, and diagnosis is frequently made at younger ages and/or at more advanced stages, the latter amenable to improved screening. Adequate evidence on the benefits of screening is lacking for most cancers in the HIV population, in whom standard practice may be suboptimal. While cancer surveillance has helped reduce mortality in the general population, and interest in risk-based strategies is growing, implementation of screening programs in the HIV care settings remains low.

Given the devastating consequences of a late diagnosis, enhancing early detection of cancer is essential for improving patient outcomes. There is an urgent need to extend the investigation in cancer screening performance to PWH, evaluating whether personalized measures according to individual risk could result in higher efficiency and improve patient outcomes.

Although lung cancer is a leading cause of death among people living with HIV (PLWH), limited research exists characterizing real-world lung cancer screening adherence among PLWH. Our objective was to compare low-dose computed tomography (LDCT) adherence among PLWH to those without HIV treated at one integrated health system. Using the University of Florida's Health Integrated Data Repository (01/01/2012-10/31/2021), we identified PLWH with at least one LDCT procedure, using Current Procedural Terminology codes(S8032/G0297/71271). Lung cancer screening adherence was defined as a second LDCT based on the Lung Imaging Reporting and Data System (Lung-RADS®). Lung-RADS categories were extracted from radiology reports using a natural language processing system. PLWH were matched with 4 randomly selected HIV-negative patients based on (+/- 1 year) age, Lung-RADS category, and calendar year. Seventy-three PLWH and 292 matched HIV-negative adults with at least one LDCT were identified. PLWH were more likely to be male (66% vs.52%,p < 0.04), non-Hispanic Black (53% vs.23%,p < 0.001), and live in an area of high poverty (45% vs.31%,p < 0.001). PLWH were more likely to be diagnosed with lung cancer after first LDCT (8% vs.0%,p < 0.001). Seventeen percent of HIV-negative and 12% of PLWH were adherent to LDCT screenings. Only 25% of PLWH diagnosed with category 4A were adherent compared to 44% of HIV-negative. On multivariable analyses, those with older age (66-80 vs.50-64 years) and with either Medicaid, charity-based, or other government insurance (vs. Medicare) were less likely to be adherent to LDCT screenings. PLWH may have poorer adherence to LDCT compared to their HIV-negative counterparts.

Lung cancer is a common cancer in people living with HIV, but the risk of cancer in this group has not been investigated for over a decade. We investigated trends in relative and absolute risk of lung cancer among people living with HIV of various age groups in the USA.

In this population-based registry linkage study, we used 2001-16 data from the HIV/AIDS Cancer Match study, which links data from HIV and cancer registries from 13 regions in the USA. We included non-Hispanic White, non-Hispanic Black, and Hispanic individuals living with HIV aged 20-89 years in our study population. Average annual percentage changes in lung cancer rates were estimated with multivariable Poisson regression, and standardised incidence ratios (SIRs) and excess absolute risks were estimated comparing people living with HIV with the general US population. We used non-parametric cumulative incidence curves to estimate the 5-year cumulative incidence of lung cancer and two AIDS-defining cancers (non-Hodgkin lymphoma and Kaposi sarcoma).

There were 3426 lung cancers in 4 310 304 person-years of follow-up in our study population. Age-standardised lung cancer incidence rates in people living with HIV declined by 6% per year (95% CI -7 to -5) during 2001-16, with greater declines in the 20-29 age group (-11%, -16 to 6) than in the older age groups (eg, -3% [-6 to 1] in those aged 70-89 years). During 2013-16, the SIR of lung cancer in people living with HIV was 2·01 (95% CI 1·52 to 2·61) in those aged 40-49 years, and 1·31 (1·12 to 1·52) in those aged 60-69 years, whereas the excess absolute risk among people living with HIV was 11·87 (3·95 to 21·89) per 100 000 person-years for those aged 40-49 years and 48·23 (6·88 to 95·47) per 100 000 person-years for those aged 60-69 years. Beginning in 2011, the 5-year cumulative incidence for lung cancer (1·36%, 95% CI 1·17 to 1·53) surpassed that of Kaposi sarcoma (0·12%, 0·06 to 0·17) and non-Hodgkin lymphoma (0·45%, 0·35 to 0·56) for people living with HIV aged 60-69 years.

Between 2001 and 2016, the risk of lung cancer decreased for people living with HIV aged 20-69 years, but remained substantially elevated compared with the general population, probably due to a combination of smoking and immunosuppression. For people living with HIV aged 60 years and older, the risk of lung cancer exceeds that of two of the most common AIDS-defining cancers, highlighting the importance of lung cancer among the growing older population of people living with HIV.

Intramural Research Program of the US National Cancer Institute.

The US Preventive Services Task Force (USPSTF) 2021 updated recommendations on lung cancer screening with chest computed tomography to apply to individuals 50-80 years of age (previously 55-80 years), with a ≥20 pack-year history (previously ≥30), whether currently smoking or quit ≤15 years ago. Despite being at higher risk for lung cancer, persons with HIV (PWH) were not well-represented in the National Lung Screening Trial, which informed the USPSTF 2013 recommendations. It is unknown or unclear how PWH are affected by the 2021 recommendations.

This study was a retrospective analysis of PWH with and without lung cancer in the Women's Interagency HIV Study and the Multicenter AIDS Cohort Study.

We identified PWH, ages 40-80 years, who currently or previously smoked, with (cases) and without lung cancer (noncases). The sensitivity and specificity of the old, new, and alternative screening criteria were evaluated in each cohort.

We identified 52 women and 19 men with lung cancer and 1950 women and 1599 men without lung cancer. Only 11 women (22%) and 6 men (32%) with lung cancer met 2013 screening criteria; however, more women (22; 44%) and men (12; 63%) met 2021 criteria. Decreased age and tobacco exposure thresholds in women further increased sensitivity of the 2021 criteria.

The 2021 USPSTF lung cancer screening recommendations would have resulted in more PWH with lung cancer being eligible for screening at the time of their diagnosis. Further investigation is needed to determine optimal screening criteria for PWH, particularly in women.

Shared decision making (SDM) is an important part of lung cancer screening (LCS) that includes discussing the risks and benefits of screening, potential outcomes, patient eligibility and willingness to participate, tobacco cessation, and tailoring a strategy to an individual patient. More than other cancer screening tests, eligibility for LCS is nuanced, incorporating the patient's age as well as tobacco use history and overall health status. Since comorbidities and multimorbidity (ie, 2 or more comorbidities) impact the risks and benefits of LCS, these topics are a fundamental part of decision-making. However, there is currently little evidence available to guide clinicians in addressing comorbidities and an individual's "appropriateness" for LCS during SDM visits. Therefore, this literature review investigates the impact of comorbidities and multimorbidity among patients undergoing LCS. Based on available evidence and guideline recommendations, we identify comorbidities that should be considered during SDM conversations and review best practices for navigating SDM conversations in the context of LCS. Three conditions are highlighted since they concomitantly portend higher risk of developing lung cancer, potentially increase risk of screening-related evaluation and treatment complications and can be associated with limited life expectancy: chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, and human immunodeficiency virus infection.

In this pilot program of low-dose computed tomography (LDCT) for the screening of lung cancer (LC) in a targeted population of people with HIV (PWH), its prevalence was 3.6%; the number needed to screen in order to detect one case of lung cancer was 28, clearly outweighing the risks associated with lung cancer screening. While data from additional cohorts with longitudinal measurements are needed, PWH are a target population for lung cancer screening with LDCT.

No other place illustrates the increasing burden of cancer than in Africa and in particular, sub-Saharan Africa. Many of the individuals to be diagnosed with cancer will be in low-resource settings in the future due to, for example, an increase in populations and aging, and high co-morbidity with infections with viruses such as human immunodeficiency virus (HIV) and human papillomavirus (HPV), as well as the presence of infectious agents linked to cancer development. Due to lack of prevention and diagnostic innovation, patients present with advanced cancers, leading to poor survival and increased mortality. HIV infection-associated cancers such as B cell lymphomas, Kaposi's sarcoma, and HPV-associated cancers such as cervical cancer are particularly noteworthy in this context. Recent reports show that a host of other cancers are also associated with viral infection and these include lung, oral cavity, esophageal, and pharyngeal, hepatocellular carcinoma, and anal and vulvar cancers. This article examines the ways in which diagnostic innovation empowered by integrative biology and informed by public health priorities can improve cancer prevention or early intervention in Africa and beyond. In addition, I argue that because diagnostic biomarkers can often overlap with novel therapeutic targets, diagnostics research and development can have broader value for and impact on medical innovation.

People living with HIV are living longer, high-quality lives; however, as they age, this population is at increased risk for developing chronic comorbidities, including cardiovascular disease, certain types of cancer (e.g., lung, anal, and liver), and diabetes mellitus. The purpose of this state-of-the-science review is to provide an evidence-based summary on common physical comorbidities experienced by people living and aging with HIV. We focus on those chronic conditions that are prevalent and growing and share behavioral risk factors that are common in people living with HIV. We will discuss the current evidence on the epidemiology, physiology, prevention strategies, screening, and treatment options for people living with HIV across resource settings.

Lung cancer is the leading cause of cancer mortality in the United States. Certain groups are at increased risk of developing lung cancer and experience greater morbidity and mortality than the general population. Lung cancer screening provides an opportunity to detect lung cancer at an early stage when surgical intervention can be curative; however, current screening guidelines may overlook vulnerable populations with disproportionate lung cancer burden. This review aims to characterize disparities in lung cancer screening eligibility, as well as access to lung cancer screening, focusing on underrepresented racial/ethnic minorities and high-risk populations, such as individuals with human immunodeficiency virus. We also explore potential system- and patient-level barriers that may influence smoking patterns and healthcare access. Improving access to high-quality health care with a focus on smoking cessation is essential to reduce the burden of lung cancer experienced by vulnerable populations.

We describe the care burden derived from a lung cancer screening program in high-risk patients with HIV. In a well-selected group with the described criteria, one annual low-dose thoracic computed tomographic exploration can be applied to 7.2% of the patients attended (95% confidence interval: 4.2-9.6), with at least one follow-up exploration in another 1.3%, with the generation of at least 2 extra visits for explanation of the protocol and results. If smoking habit does not change over the next 2 years, another 4.3% of the patients will have met the inclusion criteria. Early detection of lung cancer with low-dose thoracic computed tomographic could be of interest in HIV-infected patients because of the increased of risk but would imply an increase in care burden that must be taken into account.

We have developed a technique to measure ventilation heterogeneity (VH) on low dose chest CT scan that we hypothesize may be associated with the development of lung nodules, and perhaps cancer. If true, such an analysis may improve screening by identifying regional areas of higher risk.

Using the National Lung Screening Trial database, we identified a small subset of those participants who were labeled as having a positive screening test at 1 year (T1) but not at baseline (T0). We isolated the region in which the nodule would form on the T0 scan ("target region") and measured VH as the standard deviation of the linear dimension of a virtual cubic airspace based on measurement of lung attenuation within the region.

We analyzed 24 cases, 9 with lung cancer and 15 with a benign nodule. We found that the VH of the target region was nearly statistically greater than that of the corresponding contralateral control region (0.168 [0.110-0.226] vs. 0.112 [0.083-0.203], p = 0.051). The % emphysema within the target region was greater than that of the corresponding contralateral control region (1.339 [0.264-4.367] vs. 1.092 [0.375-4.748], p = 0.037). There was a significant correlation between the % emphysema and the VH of the target region (rho = +0.437, p = 0.026).

Our study provides the first data in support of increased local VH being associated with subsequent lung nodule formation. Further work is necessary to determine whether this technique can enhance screening for lung cancer by low dose chest CT scan.

Lung cancer is the leading cause of cancer related death among people living with HIV (PLHIV). Tobacco exposure is higher among PLHIV (38.5%) and mainly explains the increased risk of lung cancer. To reduce lung cancer mortality, two approaches need to be implemented: lung cancer screening with low-dose thoracic CT scan and smoking cessation. Low dose CT scan is feasible in PLHIV. The false positive rate is not higher than in the general population, except for cases with CD4 <200/mm³. The impact on survival remains to be assessed. Despite the high prevalence, smoking cessation research among PLHIV is scarce. Very low quality data from 11 studies showed that more intensive smoking cessation interventions were effective in achieving short-term abstinence. A single randomized phase 3 trial showed the superiority of varenicline compared to placebo in long-term smoking cessation. The maximum benefit of reducing lung cancer mortality should be obtained by combining smoking cessation and lung cancer screening.

Immunotherapy has widely changed the management of different malignancies. However, efficacy and safety of immune checkpoint inhibitors (ICIs) are not well established in people living with HIV (PLWH). Population of HIV-positive patients has deeply changed after the introduction of modern antiretroviral therapy (ART) and available data of immunotherapy in this subgroup are inadequate considering that cancer has become a leading cause of death and morbidity in this population. Moreover, there are many similarities between cancer and infectious antigen stimulation so that ICIs are even under evaluation as specific HIV treatment. Most of literature on this topic is based on small case series that suggest that immunotherapy for PLWH seems to be as effective as in HIV-negative population with a good safety profile. In this article we review literature on HIV and immunotherapy and we collect many case series available in different malignancies, with a brief focus on lung cancer.

Lung cancer is the leading cause of cancer death in people living with HIV (PWH). Surgical resection is a key component of potentially curative treatment regimens for early-stage lung cancers, but its safety is unclear in the setting of HIV. From a national cohort, we assessed potential differences in the risk of major lung cancer surgery complications by HIV status.

We linked clinical and cancer data from the Veterans Aging Cohort Study (VACS) and Veterans Affairs Corporate Data Warehouse to outcomes from the Veterans Affairs Surgical Quality Improvement Program (VASQIP) and identified 8371 patients (137 PWH, 8234 uninfected) who underwent lung cancer surgeries between 2000 and 2016.

We compared rates of 15 major short-term surgical complications by HIV status.

Use of surgical resection for early-stage lung cancer did not differ by HIV status. Lung cancer surgery postoperative (30-day) mortality was 2.0% for PWH and did not differ by HIV status (P = 0.9). Pneumonia was the most common complication for both PWH and uninfected veterans, but did not differ significantly in prevalence between groups (11.0% for PWH versus 9.4%; P = 0.5). The frequency of complications did not differ by HIV status for any complication (all P > 0.3). There were no significant predictors of postoperative complications for PWH.

In a national antiretroviral-era cohort of lung cancer patients undergoing surgical lung resection, short-term outcomes after surgery did not differ significantly by HIV status. Concerns regarding short-term surgical complications should have limited influence on treatment decisions for PWH with lung cancer.

An overall reduction in the incidence of AIDS and a change in the spectrum of lung disease have been noticed in persons living with HIV (PLHIV). Our aim was to provide an epidemiological update regarding the prevalence of lung diseases in PLHIV hospitalised in France.We analysed the prevalence of lung disease in PLHIV hospitalised in France from 2007 to 2013, from the French nationwide hospital medical information database, and assessed the association between HIV and incident noninfectious disease over 4 years of follow-up.A total of 52 091 PLHIV were hospitalised in France between 2007 and 2013. Among PLHIV hospitalised with lung disease, noninfectious lung diseases increased significantly from 45.6% to 54.7% between 2007 and 2013, whereas the proportion of patients with at least one infectious lung disease decreased significantly. In 2010, 10 067 prevalent hospitalised PLHIV were compared with 8 244 682 hospitalised non-PLHIV. In 30-49-year-old patients, HIV infection was associated with chronic obstructive pulmonary disease (COPD), chronic respiratory failure, emphysema, lung fibrosis and pulmonary arterial hypertension (PAH) even after adjustment for smoking.The emergence of noninfectious lung disease, in particular COPD, emphysema, lung fibrosis, PAH and chronic respiratory disease, in PLHIV would justify mass screening in this population.

Cancer is a leading cause of death in patients with human immunodeficiency virus (HIV) infection. With the advent of antiretroviral treatment, the risk of AIDS-defining cancers declined but the ageing of this population resulted in the emergence of other common cancers, particularly lung and hepatocellular cancer. Accordingly, screening programs similar to the general population should be implemented in patients with HIV infection. Vaccination against common oncogenic viruses is also essential. However, rates of cancer screening and vaccination against HPV and HBV are considerably low in this population, highlighting a pressing need to educate patients and healthcare professionals about the importance of cancer preventive measures in these vulnerable patients.

Lung cancer is the leading cause of non-AIDS-defining cancer deaths among HIV-infected individuals. Although lung cancer screening with low-dose computed tomography (LDCT) is endorsed by multiple national organizations, whether HIV-infected individuals would have similar benefit as uninfected individuals from lung cancer screening is unknown. Our objective was to determine the benefits and harms of lung cancer screening among HIV-infected individuals.

We modified an existing simulation model, the Lung Cancer Policy Model, for HIV-infected patients.

Population.

Annual LDCT screening from ages 45, 50, or 55 until ages 72 or 77 years.

Benefits assessed included lung cancer mortality reduction and life-years gained; harms assessed included numbers of LDCT examinations, false-positive results, and overdiagnosed cases.

For HIV-infected patients with CD4 cell count at least 500 cells/μl and 100% antiretroviral therapy adherence, screening using the Centers for Medicare & Medicaid Services criteria (age 55-77, 30 pack-years of smoking, current smoker or quit within 15 years of screening) would reduce lung cancer mortality by 18.9%, similar to the mortality reduction of uninfected individuals. Alternative screening strategies utilizing lower screening age and/or pack-years criteria increase mortality reduction, but require more LDCT examinations.

Strategies assumed 100% screening adherence.

Lung cancer screening reduces mortality in HIV-infected patients with CD4 cell count at least 500 cells/μl, with a number of efficient strategies for eligibility, including the current Centers for Medicare & Medicaid Services criteria.

Pulmonary complications remain among the most frequent causes of morbidity and mortality for individuals with HIV despite the advent of antiretroviral therapy (ART) and improvement in its efficacy and availability. The prevalence of non-infectious pulmonary diseases is rising in this population, reflecting both an increase in smoking and the independent risk associated with HIV. The unique mechanisms of pulmonary disease in these patients remain poorly understood, and direct effects of HIV, genetic predisposition, inflammatory pathways, and co-infections have all been implicated. Lung cancer, chronic obstructive pulmonary disease (COPD), and pulmonary hypertension are the most prevalent non-infectious pulmonary diseases in persons with HIV, and the risk of each of these diseases is higher among HIV-infected (HIV+) persons than in the general population. This review discusses the latest advances in the literature on these important complications of HIV infection.

The number of women living with HIV continues to increase. Thirty years into the AIDS epidemic, we now expect those with access to highly active antiretroviral to survive into their seventh decade of life or beyond. Increasingly, the focus of HIV care is evolving from preventing opportunistic infections and treating AIDS-defining malignancies to strategies that promote longevity. This holistic approach to care includes detection of malignancies that are associated with certain viral infections, with chronic inflammation, and with lifestyle choices. The decision to screen an HIV-infected women for cancer should include an appreciation of the individualized risk of cancer, her life expectancy, and an attempt to balance these concerns with the harms and benefits associated with specific cancer screening tests and their potential outcome. Here, we review cancer screening strategies for women living with HIV/AIDS with a focus on cancers of the lung, breast, cervix, anus, and liver.

Lung cancer screening with low-dose computed tomography (LDCT) of high-risk groups in the general population is recommended by several authorities. This may not be feasible in people living with HIV (PLWHIV) due to higher prevalence of nodules. We therefore assessed the prevalence of positive computed tomography (CT) images and lung cancers in PLWHIV.

The Copenhagen comorbidity in HIV infection (COCOMO) study is an observational, longitudinal cohort study. Single-round LDCT was performed with subsequent clinical follow-up (NCT02382822).

Outcomes included histology-proven lung cancer identified by LDCT and positive CT images (noncalcified nodules) in the entire cohort and in the high-risk group (>50 years of age and >30 pack-years). We also assessed the procedures and adverse events, and clinical factors associated with a positive CT image.

LDCT was performed in 901 patients, including 113 at high risk for lung cancer. A positive image was found in 28 (3.1% of the entire cohort and 9.7% of the high-risk group). Nine patients (all in the high-risk group) had invasive procedures undertaken with no serious adverse events. Lung cancer (stages IA, IIA, and IIIA) was diagnosed in three patients from the high-risk group (2.7%). CD4 cell count less than 500 cells/μl and CD4 nadir less than 200 cells/μl were each independently associated with increased odds of a positive image odds ratio 2.32 [95% confidence interval: 1.01-5.13, P = 0.04] and odds ratio 2.63 [95% confidence interval: 1.13-6.66, P = 0.03].

Randomized LDCT screening trials in PLWHIV are nonexistent, but these findings are comparable with screening rounds from the general population in terms of prevalence of lung cancer and positive CT images.

HIV-infected individuals have improved access to antiretroviral therapy. This has resulted in a shift in causes of mortality from infectious diseases to noncommunicable diseases including cardiovascular disease, chronic kidney disease (CKD) and malignancies. This review will look at the epidemiological shift, risk factors for the development of these diseases and examine some of the supporting laboratory diagnostic testing, which may be required.

Risk factors for the development of these diseases in HIV-infected patients include underlying genetic predisposition, lifestyle risk factors, chronic inflammation as a consequence of HIV infection, the presence and persistence of opportunistic infections and in some cases, highly active antiretroviral therapy, itself. Morbidity and mortality from HIV-associated conditions are increasing in low-income and middle-income countries (LMICs) with increased prevalence of HIV-associated cancers, cardiovascular disease and CKD.

Management of these conditions in LMICs requires an integrated pathology solution that will enable early screening, diagnosis and monitoring.

Solid organ transplant patients are at heightened risk of several cancers compared to the general population. Secondary to a higher number of procedures and better survival after transplantation, cancer is a rising health concern in this situation. Limited data exist for lung cancer (LC) after renal transplantation. We report here the most important series of renal transplant recipients with lung cancer.

Retrospective study of all cases of LC diagnosed in three French Renal Transplant Units from 2003 to 2012. A control group consisted of non-transplant patients with LC matched with the cases for age (<30; 30-50; 50-65; >65 years), gender and diagnosis date. We recruited two controls for each case.

Thirty patients (median age 60 years; range 29-85; male/female ratio 80/20%) with LC were analysed. LC incidence was 1.89/1000 person-years over the period 2008-2012. All patients were former or active smokers (median 30 pack-years). Transplanted patients had significantly more comorbidities, mainly cardiovascular disease. The median interval of time from kidney transplantation (KT) to diagnosis of LC was 7 years (range 0.5-47 years). LC was incidentally diagnosed in 40%. Most patients (70%) had advanced LC (stage III or IV) disease. Stage of LC at diagnosis was similar in cases and controls. Surgery and chemotherapy were proposed to the same proportion of patients. In cases, mortality was cancer related in 87% and median survival time after diagnosis was 24 months. Survival was not significantly different between the 2 groups.

Despite frequent medical and radiological examinations, diagnosis of LC is usually made at an advanced stage and the overall prognosis remains poor.

Lung cancer (LC) is one of the most common non-AIDS (acquired immune deficiency syndrome)-defining malignancies. It occurs more frequently in persons living with human immunodeficiency virus (PLWHIV) than in the HIV-negative population. Compared to their HIV-negative counterparts, patients are usually younger and diagnosed at more advanced stages. The pathogenesis of LC in PLWHIV is not fully understood, but immunosuppression in combination with chronic infection and the oncogenic effects of smoking and HIV itself all seem to play a role. Currently, no established preventive screening is available, making smoking cessation the most promising preventive measure. Treatment protocols and standards are the same as for the general population. Notably, immuno-oncology will also become standard of care in a significant subset of HIV-infected patients with LC. As drug interactions and hematological toxicity must be taken into account, a multidisciplinary approach should include a physician experienced in the treatment of HIV. Only limited data is available on novel targeted therapies and checkpoint inhibitors in the setting of HIV.

Since the advent of antiretroviral therapy (ART), non-infectious pulmonary disorders have become common comorbidities in the human immunodeficiency virus (HIV) positive population. Clinicians caring for those with HIV disease should be aware of the prevalence of non-infectious pulmonary disorders. A comprehensive understanding is required to diagnosis and manage these syndromes appropriately. Areas covered: This review focuses on the epidemiology, risk factors, pathogenesis, clinical feature and diagnosis, and treatment of HIV-related chronic obstructive pulmonary disease (COPD), lung cancer, pulmonary hypertension. Expert Commentary: The prevalence of COPD in the HIV population is frequent and requires appropriate diagnosis and treatment. HIV-positive individuals with lung cancer carry a poorer prognosis and require early diagnosis and treatment. A complex condition exists with pulmonary hypertension in the HIV population and requires a high degree of clinical suspicion for early diagnosis.

Lung cancer is emerging as a leading cause of death in HIV-infected persons. This review will discuss the latest scientific evidence regarding the mechanisms driving lung cancer risk in HIV infection, the clinical presentation of lung cancer in HIV-infected persons and recent data regarding the outcomes, treatment and prevention of lung cancer in this group.

Increased risk of lung cancer in HIV-infected persons is primarily due to higher smoking rates, but emerging evidence also implicates immunosuppression and inflammatory processes. Lung cancer outcomes may be worse in HIV-infected persons in the antiretroviral era, but this may stem, in part, from treatment disparities. Early detection of lung cancer using chest computed tomography (CT) is being increasingly adopted for smokers in the general population, and recent studies suggest that it may be safe and efficacious in HIV-infected smokers.

Lung cancer is an important complication associated with chronic HIV infection. It is associated with unique HIV-related causal mechanisms, and may be associated with worse outcomes in some HIV-infected persons. Smoking cessation and early cancer detection with chest CT are likely to benefit HIV-infected smokers.

Human immunodeficiency virus (HIV) is now managed as a chronic disease. Non-infectious pulmonary conditions have replaced infection as the biggest threat to lung health, particularly as HIV cohorts age, but there is no consensus on how best to maintain long-term lung health. We review the epidemiology and pathogenesis of chronic obstructive pulmonary disease (COPD), pulmonary arterial hypertension (PAH), and lung cancer in HIV-seropositive individuals.

Diagnoses of COPD are now up to 50% more prevalent in HIV-seropositive individuals than HIV-uninfected controls, and prospective pulmonary function studies find significant impairment in 7% to more than 50% of HIV-seropositive individuals. The prevalence of HIV-PAH is 0.2-0.5%, and lung cancer is two to three times more prevalent in HIV-seropositive individuals. Although host factors such as age and smoking have a role, HIV is an independent contributor to the pathogenesis of COPD, PAH, and lung cancer. Chronic inflammation, immune senescence, oxidative stress, and direct effects of viral proteins are all potential pathogenetic mechanisms. Despite their prevalence, non-infectious lung diseases remain underrecognized and evidence for effective screening strategies in HIV-seropositive individuals is limited.

COPD, PAH, and lung cancer are a growing threat to lung health in the highly active antiretroviral therapy era necessitating early recognition.

A shift in mortality and morbidity has been observed in people living with human immunodeficiency virus (PLWHIV) from acquired immunodeficiency syndrome (AIDS) to non-AIDS diseases. Lung cancer has the highest incidence rates among all the non-AIDS-defining malignancies and is associated with mortality rates that exceed those of other cancers. Strategies to increase lung cancer survival in PLWHIV are needed. Lung cancer screening with chest LDCT has been shown to be efficient in the general population at risk. The objective of this review is to discuss lung cancer screening with chest computed tomography in PLWHIV. Lung cancer screening in PLWHIV is feasible. Whether PLWHIV could benefit from an age threshold for screening that is earlier than the minimum age of 55 years usually required in the general population still needs further investigation. Studies evaluating smoking cessation programs and how they could be articulated with lung cancer screening programs are also needed in PLWHIV.

Pulmonary malignancies are a major source of morbidity and mortality in HIV-infected persons. Non-AIDS-defining lung cancers (mostly non-small cell lung cancers) are now a leading cause of cancer death among HIV-infected persons. HIV-associated factors appear to affect the risk of lung cancer and may adversely impact cancer treatment and outcomes. HIV infection also may modify the potential harms and benefits of lung cancer screening with computed tomography. AIDS-defining lung malignancies include pulmonary Kaposi sarcoma and pulmonary lymphoma, both of which are less prevalent with widespread adoption of antiretroviral therapy.

Lung cancer screening with chest computed tomography (CT) is beneficial in smokers aged 55 to 74 years. We studied the risks, benefits and feasibility of early lung cancer diagnosis with CT in HIV-infected smokers.

French, multicentre, single round chest CT study in France, realized between February 2011 and June 2012.

Patients were HIV-infected smokers at least 40 years, at least 20 pack-years, with a CD4 T-lymphocyte nadir count below 350 cells/μl.

Single chest CT with a proposed standardized workup algorithm of positive images.

The outcome was the number of histologically proven lung cancers diagnosed by CT with a 2-year follow-up.

Median age of the 442 included patients was 49.8 years, 81.6% were under 55 years, 84% were men, median smoking was 30 pack-years, median nadir and last CD4 cell counts were 168 and 574 cells/μl, respectively, and 90% of patients had a plasma HIV RNA below 50 copies/ml. A positive image at baseline was reported in 94 (21%) patients, and 15 (3.4%) patients had 18 invasive procedures with no serious adverse events. Lung cancer was diagnosed in 10 patients (six at early stages), of which nine (2.0%, 95% confidence interval: 0.9-3.8) were CT detected, and eight in patients below 55 years.

Early lung cancer diagnosis with CT in HIV-infected smokers was feasible, safe, and yielded a significant number of cancers. Lung cancer screening of HIV-infected smokers with an important history of immunodeficiency revealed a substantial number of cancers at younger ages than the targeted range in the general population.

The advent of combination antiretroviral treatment (cART) has been followed by a decrease in HIV-associated morbidity and mortality, but also by an apparent increase in the incidence of non-AIDS-defining cancers (NADCs). The risk of lung cancer is substantially higher in HIV-infected patients than in the general population, in part due to aging and tobacco use, and it is the most frequent NADC. The management of lung cancer in HIV-infected patients has some peculiarities that need to be taken into account. This review focuses on the epidemiology, risk factors, and clinical management of lung cancer in HIV-infected patients. In addition, screening tools and future perspectives are also discussed.

Malignancies represent a major cause of morbidity and mortality in human immunodeficiency virus (HIV)-infected patients. The introduction of combined antiretroviral therapy has modified the spectrum of malignancies in HIV infection with a decreased incidence of acquired immunodeficiency syndrome (AIDS) malignancies such as Kaposi's sarcoma and non-Hodgkin's lymphoma due to partial immune recovery and an increase in non-AIDS-defining malignancies due to prolonged survival. Management of HIV-infected patients with cancer requires a multidisciplinary approach, involving both oncologists and HIV physicians to optimally manage both diseases and drug interactions between anticancer and anti-HIV drugs. The French CANCERVIH group presents here a review and an experience of managing non-AIDS malignancies in HIV-infected individuals.

The purpose of this study was to describe the baseline characteristics and results of the initial 18 months of our clinical computed tomography (CT) lung cancer screening program in an ethnically diverse, poor, predominantly overweight, and obese population, which differs dramatically from the National Lung Screening Trial population.

All patients had a physician referral for CT lung cancer screening and met National Lung Screening Trial eligibility criteria. Infrastructure developed for the program included a standardized results report [Bronx score of 1 to 5 (modeled on BI-RADS)] for the electronic medical record and a dedicated bilingual screening coordinator. If the patient's insurance did not cover CT screening, a fee of $75 was charged.

A total of 320 patients [54% (174) men, mean age 64 y] underwent initial CT lung cancer screening from December 18, 2012 to July 3, 2014. The median pack-years was 47, and 68% (218) were current smokers. Twenty-six percent (84) were white, and 70% (223) were overweight (101) or obese (122). The lung cancer prevalence was 2.2% (7/320). Seventy-eight percent (7/9) of patients with CT findings positive for lung cancer (score 5a, 5b) had proven lung cancer; 1 had stage 1 (1B) disease, and 6 had stage IIA or higher disease. The false-positive rate for a Bronx score ≥3 was 19% (60). Medicare and Medicaid insure 80% of the institution's overall population but only 38% (121) of the CT screening patients.

CT screening is feasible in a diverse inner-city population with the support of a robust infrastructure. Further study is needed to determine whether CT screening will confer a mortality benefit in this population.

People living with human immunodeficiency virus (HIV) are living longer since the advent of effective combined antiretroviral therapy (cART). While cART substantially decreases the risk of developing some cancers, HIV-infected individuals remain at high risk for Kaposi sarcoma, lymphoma, and several solid tumors. Currently HIV-infected patients represent an aging group, and malignancies have become a leading cause of morbidity and mortality. Tailored cancer-prevention strategies are needed for this population. In this review we describe the etiologic agents and pathogenesis of common malignancies in the setting of HIV, as well as current evidence for cancer prevention strategies and screening programs.

Asymptomatic patients with human immunodeficiency virus (HIV) infection are at increased risk of vascular disease. Whether asymptomatic HIV patients have increased prevalence or structural differences in coronary artery plaques is not clear.

Pubmed, Cochrane and Google Scholar were searched for articles evaluating asymptomatic HIV patients evaluated with coronary computed tomography. The prevalence of coronary stenosis (defined as >30% and >50%), of calcified coronary plaques (CCP) viewed as more 'stable' plaques, and of non-calcified coronary plaques (NCP) viewed as more 'vulnerable' plaques were the end points of interest.

9 studies with 1229 HIV patients and 1029 controls were included. No significant differences were detected about baseline cardiovascular risk profile. The prevalence of significant coronary stenosis>30% or >50% did not differ between HIV+ and HIV- patients (42% [37-44] and 46% [35-52] with an Odds Ratio [OR] of 1.38 [0.86-2.20] for >30% stenosis) and (15% [9-21] and 14% [7-22] with an OR of 1.11 [0.81-1.52]), respectively. The prevalence of calcified coronary plaques (CCP) (31% [24-32] and 21% [14-30] with an OR of 1.17 [0.63-2.16]) also did not differ among HIV+ and HIV- patients. On the contrary rates of NCP were >3-fold higher in HIV-positive patients [58% (48-60) and 17% (14-27) with an OR of 3.26 (1-30-8.18)], with an inverse relationship with CD4 cell count at meta-regression (Beta -0.20 [-0.35-0.18], p 0.04).

Asymptomatic HIV patients present a similar burden of coronary stenosis and calcified coronary artery plaques but significantly higher rates of non-calcific coronary plaques at computed tomography. The association between HIV infection, reduced CD4 cell counts and higher prevalence on non-calcific coronary artery plaques may shed light into the pathogenesis in HIV-associated coronary artery disease, stressing the importance of primary prevention in this population.
