Incidence Of non-AIDS Defining Cancers Research Articles

Nationwide Longitudinal Annual Survey of HIV/AIDS Referral Hospitals in Japan From 1999 to 2021: Trend in Non-AIDS-defining Cancers Among Individuals Infected With HIV-1.

Non-AIDS-defining cancers (NADCs) in patients infected with HIV have recently attracted attention because of the improved survival of this patient population. To obtain accurate data, a longitudinal study is warranted for the nationwide surveillance of the current status and national trend of NADCs in patients infected with HIV in Japan. An annual nationwide surveillance of NADCs in patients infected with HIV-1 in Japan from 1999 to 2021. An annual questionnaire was sent to 378 HIV/AIDS referral hospitals across Japan to collect data (clusters of differentiation 4-positive lymphocytes, time of onset, outcomes, and antiretroviral therapy status) of patients diagnosed with any of the NADCs between 1999 and 2021. The response and case-capture rates for the questionnaires in 2021 were 37.8% and 81.2%, respectively. The number of reported NADC cases subsequently increased since the beginning of this study. Evaluation of the case counts of NADCs demonstrated a high incidence of lung, colorectal, gastric, and liver cancers as the top 4 cancers. Pancreatic cancer (0.63), lung cancer (0.49), and leukemia (0.49) had the highest mortality rates among the NADCs. Trends of NADCs regarding transmission routes were maintained over the years in male individuals who have sex with male individuals compared with heterosexual male individuals and female individuals. We demonstrated an increasing trend in the incidence of NADCs over a period of 23 years in Japan. The current data highlighted the importance of raising awareness regarding cancer management for patients infected with HIV in Japan.

The Trends and Risk Factors of AIDS-Defining Cancers and Non-AIDS-Defining Cancers in Adults Living with and without HIV: A Narrative Review.

People living with HIV (PLHIV) are at a high-risk of developing AIDS-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs). This review is aimed at exploring available evidence regarding the trends of ADCs and NADCs and the associated risk factors among adult PLHIV. We conducted a comprehensive search of PubMed, Web of Science, and EBSCO host databases to identify articles published between 2010 and 2023 that reported incidence and mortality rates of cancer, including ADCs and NADCs among PLHIV. We compared trends and rates in PLHIV with HIV-negative adults and further assessed related risk factors. A total of 1886 potentially eligible articles were screened, and of these, 36 were included in this study. More than 50% (n = 20) of these were based in high-income countries. Seventeen studies reported a higher prevalence of NADCs compared to ADCs, with twelve of these conducted in high-income countries. Conversely, eight out of twelve studies reporting a higher prevalence of ADCs versus NADCs were from low-and-middle and upper-middle-income countries. Ten studies indicated a higher incidence of ADCs (6 studies) and NADCs (4 studies) among PLHIV compared to HIV-negative individuals. In contrast, only two studies observed an increase in NADCs among the HIV-negative population. In comparing mortality, seven out of nine studies showed elevated NADC-related deaths compared to ADCs. The main risk factors identified for any cancer, NADCs, and related mortality were advancing age, and longer duration of HIV infection, while lower CD4 cell counts (<200 cells/μl), was associated with both ADC and NADC occurrences. Chronic HIV infection combined with advancing age in PLHIV taking antiretroviral therapy appears to have contributed to increasing cancer burden, particularly the incidence of NADCs and associated mortality. These findings stress the importance of screening for high-risk cancers among PLHIV for early detection and treatment to ensure improved outcomes.

Spectrum and Incidence Trends of AIDS- and Non-AIDS-Defining Cancers between 2010 and 2015 in the French Dat'AIDS Cohort.

Cancer risk is higher in people living with HIV (PLWH) compared with the general population, and cancers related to age are expected to be most prevalent. We determined the spectrum and incidence rates of AIDS-defining cancers (ADC) and non-AIDS-defining cancers (NADC) and of lung, Hodgkin lymphoma (HL), head and neck (HNC), colon-rectum, anal, liver, breast, prostate, and urinary bladder cancers between January 2010 and December 2015 in the French Dat'AIDS cohort. Incidence rates were calculated by year and compared using the χ 2 test for linear trend. Standardized incidence ratios [SIR (95% confidence interval)] were calculated relative to the French general population. Among 44,642 patients, corresponding to 180,216.4 person-years (PY), 1,440 cancer cases occurred in 1,314 patients. ADC incidence was 191.4 (172.3-212.7)/105 PY and declined over time overall and in men, whereas NADC incidence was higher [548.8 (515.6-584.1)/105 PY] and did not change. In men, non-Hodgkin lymphoma was the most common cancer, but prostate cancer had the highest incidence among NADCs. Breast cancer was the most common cancer in women. SIRs were higher for cervical cancer [1.93 (1.18-3.14)], HNC in women [2.4 (1.4-4.2)], liver [overall: 3.8 (3.1-4.6); men: 3.2 (2.5-4.0); women: 12.9 (8.3-20.0)], and HL [overall: 13.8 (11.1-17.1); men: 16.2 (12.9-20.4); women: 6.2 (3.22-11.9)] but lower for lung [overall: 0.7 (0.6-0.9); men: 0.7 (0.5-0.8)], prostate [0.6 (0.5-0.7)], and breast cancers [0.6 (0.4-0.7)]. Spectrum of NADCs has changed, with prostate and breast cancers becoming the most common despite their lower SIR. These results confirm the need to maintain regular epidemiologic cancer monitoring in order to update screening guidelines.

Increased risk of non-AIDS-defining cancers in Asian HIV-infected patients: a long-term cohort study

BackgroundData on the long-term risks of non-AIDS defining cancers (NADCs) are limited, especially in Asians. The incidence of NADCs may correlate with the epidemiological trend of cancers or oncogenic infection in each country, and thus the target cancers would be different between Western and Asian countries. We aimed to elucidate the incidence of NADCs and its predictive factors in Asian HIV-infected patients.MethodsSubjects were HIV-infected patients (n = 1001) periodically followed-up for 9 years on average. NADCs were diagnosed by histopathology and/ or imaging findings. Standardized incidence ratios (SIR) were calculated as the ratio of the observed to expected number of NADCs for comparison with an age-and sex-matched general population. Cox’s proportional hazards model was used to estimate hazard ratios (HR).ResultsDuring the median follow-up of 9 years, the 10-year cumulative incidence of NADCs was 6.4%.At NADC diagnosis, half of patients presented at age 40–59 years and with advanced tumor stage. Compared with the age-and sex-matched general population, HIV-infected patients are at increased risk for liver cancer (SIR, 4.7), colon cancer (SIR, 2.1), and stomach cancer (SIR, 1.8). In multivariate analysis, a predictive model for NADCs was developed that included age group (40–49, 50–59, 60–69, and ≥ 70 years), smoker, HIV infection through blood transmission, and injection drug use (IDU), and HBV co-infection. The c-statistic for the NADCs predictive model was 0.8 (95%CI, 0.8–0.9, P < 0.001). The higher 10-year incidence rate of NADCs was associated with increasing prediction score.ConclusionsLiver and colon cancer risk was elevated in Asian HIV-infected individuals, similar to in Western populations, whereas stomach cancer risk was characteristically elevated in Asian populations. Half of Asian NADC patients were aged 40–59 years and had advanced-stage disease at diagnosis. Periodic cancer screening may be warranted for high-risk subpopulations with smoking habit, HIV infection through blood transmission or IDU, and HBV co-infection, and screening should be started over 40 years of age.

Are Non-HIV Malignancies Increased in the HIV-Infected Population?

The introduction of antiretroviral therapy (ART) has revolutionized HIV infection management, resulting in improved outcomes and survival for people living with HIV (PLWH). However, as PLWH are living longer and aging, non-AIDS-defining cancers (NADCs) represent a significant source of morbidity and mortality in the HIV-infected population. Here, we review the epidemiology of NADCs in PLWH. Cancer mortality among PLWH is much higher than that among the general population. Up to 10% of deaths among PLWH have been attributed to NADCs. Furthermore, PLWH have an increased risk for specific NADCs, including lung cancer, hepatocellular carcinoma, head and neck cancers, anal cancer, and Hodgkin lymphoma. In the past decade, the incidence rates of AIDS-defining cancers (ADCs) have been decreasing while the incidence rates of NADCs have been increasing. In particular, the incidence of specific NADCs are changing at different rates. For example through 2010, the incidence rates for anal, liver, and prostate cancers among PLWH had increased, while incidence rates for lung cancer had decreased and incidence rates for colorectal cancer remained relatively stable over time. However, as early ART becomes more prevalent and the percentage of PLWH over 50 increases, these trends may evolve further. Incidence of NADCs should be expected to increase further as the PLWH population continues to age. Screening and prevention for these cancers among the HIV-infected population should be emphasized.

Cancer incidence and mortality for all causes in HIV-infected patients over a quarter century: a multicentre cohort study.

BackgroundWe aimed to assess cancer incidence and mortality for all-causes and factors related to risk of death in an Italian cohort of HIV infected unselected patients as compared to the general population.MethodsWe conducted a retrospective (1986–2012) cohort study on 16 268 HIV infected patients enrolled in the MASTER cohort. The standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs) were computed using cancer incidence rates of Italian Cancer Registries and official national data for overall mortality. The risk factors for death from all causes were assessed using Poisson regression models.Results1,195 cancer cases were diagnosed from 1986 to 2012: 700 AIDS-defining-cancers (ADCs) and 495 non-AIDS-defining-cancers (NADCs). ADC incidence was much higher than the Italian population (SIR = 30.8, 95% confidence interval 27.9-34.0) whereas NADC incidence was similar to the general population (SIR = 0.9, 95% CI 0.8-1.1). The SMR for all causes was 11.6 (11.1-12.0) in the period, and it decreased over time, mainly after 1996, up to 3.53 (2.5-4.8) in 2012. Male gender, year of enrolment before 1993, older age at enrolment, intravenous drug use, low CD4 cell count, AIDS event, cancer occurrence and the absence of antiretroviral therapy were all associated independently with risk of death.ConclusionsIn HIV infected patients, ADC but not NADC incidence rates were higher than the general population. Although overall mortality in HIV infected subjects decreased over time, it is about three-fold higher than the general population at present.

HIV and cancer: a comparative retrospective study of Brazilian and U.S. clinical cohorts.

BackgroundWith successful antiretroviral therapy, non-communicable diseases, including malignancies, are increasingly contributing to morbidity and mortality among HIV-infected persons. The epidemiology of AIDS-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs) in HIV-infected populations in Brazil has not been well described. It is not known if cancer trends in HIV-infected populations in Brazil are similar to those of other countries where antiretroviral therapy is also widely available.MethodsWe performed a retrospective analysis of clinical cohorts at Instituto Nacional de Infectologia Evandro Chagas (INI) in Rio de Janeiro and Vanderbilt Comprehensive Care Clinic (VCCC) in Nashville from 1998 to 2010. We used Poisson regression and standardized incidence ratios (SIRs) to examine incidence trends. Clinical and demographic predictors of ADCs and NADCs were examined using Cox proportional hazards models.ResultsThis study included 2,925 patients at INI and 3,927 patients at VCCC. There were 57 ADCs at INI (65% Kaposi sarcoma), 47 at VCCC (40% Kaposi sarcoma), 45 NADCs at INI, and 82 at VCCC. From 1998 to 2004, incidence of ADCs remained statistically unchanged at both sites. From 2005 to 2010, ADC incidence decreased in both cohorts (INI incidence rate ratio per year = 0.74, p < 0.01; VCCC = 0.75, p < 0.01). Overall Kaposi sarcoma incidence was greater at INI than VCCC (3.0 vs. 1.2 cases per 1,000 person-years, p < 0.01). Incidence of NADCs remained constant throughout the study period (overall INI incidence 3.6 per 1,000 person-years and VCCC incidence 5.3 per 1,000 person-years). Compared to general populations, overall risk of NADCs was increased at both sites (INI SIR = 1.4 [95% CI 1.1-1.9] and VCCC SIR = 1.3 [1.0-1.7]). After non-melanoma skin cancers, the most frequent NADCs were anal cancer at INI (n = 7) and lung cancer at VCCC (n = 11). In multivariate models, risk of ADC was associated with male sex and immunosuppression. Risk of NADC was associated with increased age.ConclusionsIn both cohorts, ADCs have decreased over time, though incidence of KS was higher at INI than VCCC. Rates of NADCs remained constant over time at both sites.Electronic supplementary materialThe online version of this article (doi:10.1186/1750-9378-10-4) contains supplementary material, which is available to authorized users.

The evolving scenario of non-AIDS-defining cancers: challenges and opportunities of care.

The impact of highly active antiretroviral therapies (HAART) on the risk of non-AIDS-defining cancers (NADCs) and the role of biological and clinical factors in their pathogenesis are debated issues. The purpose of this review is to examine the epidemiology, etiology, and not-yet-defined pathogenic characteristics of NADCs and discuss topics such as treatment strategies, comorbidity, and multidrug interactions. Four types of NADCs that deserve special attention are examined: anal cancer, Hodgkin lymphoma (HL), hepatocellular carcinoma, and lung cancer. The PubMed database and the Cochrane Library were searched by focusing on NADCs and on the association among NADCs, HAART, aging, and/or chronic inflammation. All articles were reviewed to identify those reporting variables of interest. NADC incidence is twofold higher in patients with HIV/AIDS than in the corresponding general population, and this elevated risk persists despite the use of HAART. The mechanisms that HIV may use to promote the development of NADCs are presently unclear; immunological mechanisms, either immunodeficiency and/or immunoactivation, may play a role. Recent clinical studies have suggested that equivalent antineoplastic treatment is feasible and outcome can be similar in HIV-infected patients on HAART compared with uninfected patients for the treatment of HL and anal and lung cancers. However, patients with advanced HIV disease and/or aging-related comorbidities are likely to experience worse outcomes and have poorer tolerance of therapy compared with those with less advanced HIV disease.

Trends and Predictors of Non–AIDS-Defining Cancers in Men and Women With HIV Infection

The incidence of non-AIDS-defining cancers (NADCs) in HIV-positive patients has increased over recent years. Most studies of the risk and spectrum of NADCs are primarily based on male populations, and only a few have provided specific information regarding females. We retrospectively analyzed all incident NADCs occurring in a cohort of HIV-positive patients followed up between 1985 and 2011. Incidence rates before and after the introduction of highly active antiretroviral therapy (HAART) were examined using Poisson regression models. Standardized incidence ratios (SIRs) were used to compare the cancer risk of HIV-infected subjects with that of the age- and gender-matched general population as estimated by the Milan Cancer Registry. Five thousand nine hundred twenty-four patients (4382 men and 1542 women) contributed 50,990 person-years to the follow-up. Among them, 144 had new NADC diagnosis. The overall incidence increased from 1.0 case/1000 person-years in the pre-HAART period to 4.5 cases/1000 person-years in the HAART period (P < 0.01). In women, the risks were higher than expected in the case of cancer of the vulva (SIR = 69.2), Hodgkin lymphoma (SIR = 7.5), anal cancer (SIR = 41.2), and lung cancer (SIR = 4.8). In men, the risks were higher than expected in the case of anal cancer (SIR = 91.5), Hodgkin lymphoma (SIR = 13.0), tonsil cancer (SIR = 10.9), lung cancer (SIR = 2.1), and liver cancer (SIR = 7.1). The spectrum and incidence of NADCs in our cohort increased over time. The incidence of NADCs, especially virus- and smoking-associated cancers, was significantly higher than expected in HIV-positive men and women.

A retrospective analysis of all non-AIDS defining cancers (NADC): A subset analysis of the County Hospital AIDS Malignancy Project (CHAMP).

1611 Background: County Hospital (CCH) with its HIV clinic, the CORE Center (CC) is the largest provider for HIV patients (pts) in Chicago, treating over 5,500 HIV pts yearly. There is paucity of data on characteristics of HIV+ cancers (ca) in the inner city. The CHAMP cohort is a retrospective study of all HIV associated cancers at CC and CCH over past 14 years (yrs). We analyzed all of the NADC from this cohort. Methods: All HIV pts with NADC were identified from the CHAMP cohort and retrospectively reviewed for HIV and cancer characteristics, overall survival (OS), and pt demographics. Statistics: Survival data was analyzed using Kaplan-Meier analysis and Cox Proportional Hazards model. Results: Of 438 pts identified, 157 were NADC representing 21 ca. The average (ave) age was 48 yrs (range 44-57), with prostate ca having highest age presentation. Over the past 10 yrs, the number of NADC has risen from 10 to over 20 each yr. Unlike historical controls (HC) where lung ca is most common, anal ca (21%) was most frequent followed by lung ca (17%). Prostate, head and neck (HNSCC), liver, and colorectal ca were seen in 9, 9, 8, and 7% respectively. 65% of pts were African Americans (AA) and 18% Caucasians. 78% of all NADC were men. 45% of anal ca present with stage IIIa/b disease, moderately to poorly differentiated ca in 48%, with a median OS of 34 mo. CD4 count did not alter OS but stage predicted better outcomes. 86% lung ca presented as stage III/IV disease with ave CD4 count 204. Histologically, 36% were SCC, 28% adenosquamous and 20% adenocarcinoma. OS was 5.5 mo and did not change by histology, CD4, or age. 68% HNSCC present with stage IVa/b but no IVc. Ave age was 48 yrs with an OS of 18mo. 50% were oropharyngeal compared to 22% in HC. Conclusions: Based on data by Sheilds et. al, CCH treats just over 1% of the country’s NADC population. We demonstrate a higher incidence of NADC over time, dominated by a younger, AA and male population. Each ca presents with advanced stage 45-86% and poorly differentiated tumors ranging from 15-30%. The OS of each cancer is consistent with HC with exception of HNSCC. As HIV pts age becoming prone to cancers of elderly, education and screening of inner city HIV pts will help improve cancer rates.

Ten years later: A single hospital experience with malignancy in HIV/AIDS

We present our experience in the era of HAART with 5,112 patients having HIV infection or AIDS, treated between 2002 and 2006 in our hospital, 182 of whom had malignancies (3.56%). We compared our findings to those from a similar cohort of patients studied 10 years earlier. The charts were reviewed and data was electronically collected as in our 1993-1998 study. Similar statistical analyses were performed in both studies and the results were compared. For the current study the average patient age increased by 9 years. A decrease in AIDS-defining cancers (ADC), from 63.6% to 37.3% and a higher incidence of non-AIDS-defining cancers (NADC), 62.7 as opposed to 37.9% was found. No decrease in the incidence of non-Hodgkin's B cell lymphoma (NHL) was noted. There was an increase in the number of opportunistic infections notably hepatitis C virus (HCV) and hepatitis B virus (HBV). HIV/AIDS patients on HAART are older, have lower rates of AIDS related Kaposi's sarcoma and a higher incidence of NADCs than did patients in the early HAART era. No decrease in the proportion of NHL was observed.

Treating HIV+ patients for non-AIDS-defining cancers (NADCs) in the era of targeted chemotherapy: An AIDS malignancy consortium study of sunitinib in patients on ART.

TPS161 Background: The cumulative NADC incidence is approaching that of AIDS-defining cancers in HIV-infected persons in populations where effective antiretroviral therapy (ART) is commonly used. Marked increases in risk are seen in certain cancers, including lung, liver, head and neck, anogenital, and Hodgkin's lymphoma. Treatment of NADCs may be complicated by drug-drug interactions between ART and chemotherapy, including ART-mediated induction or inhibition of metabolizing enzymes, especially of the CYP450 family. To study these interactions, with the goal of formulating treatment recommendations on the use of targeted anticancer agents to treat NADCs in HIV+ patients, the AIDS Malignancy Consortium has launched the first clinical study to address this emerging epidemic. Sunitinib is a multi-targeted TKI of PDGFR, VEGFR1/3, KIT, FLT3, SCF, and RET. It is a prodrug which is metabolized into the active metabolite SU012662 by CYP3A4, which is then further inactivated by CYP3A4. Methods: The primary objectives of AMC 061 is to determine the safety and to investigate the effect of ART on the PK of sunitinib in HIV+ cancer patients. Secondary objectives include investigating: the efficacy of using sunitinib to treat NADCs; the effects of sunitinib on ART pharmacokinetics, CD4 count, and HIV viral load; and pharmacogenetic correlations. Subjects are stratified into three groups based on their ART therapy: (1) non- nucleoside reverse transcriptase inhibitor (NNRTI)-based therapy, (2) non-ritonavir protease inhibitor (PI)-based therapy, and (3) ritonavir PI-based therapy. A phase I dose escalation design is used to determine the MTD of sunitinib (25, 37.5, or 50 mg daily) in each group, with both inter- and intra-patient dose escalation allowed. Between 21 and 42 patients will be enrolled. Intensive PK and PD monitoring is performed throughout Cycle 1. The trial was initiated in late 2009, and is open at AMC sites and those of the NCI Organ Dysfunction Working Group. As of 1/2010, three patients have been enrolled. Treatment has been well tolerated and no DLTs have been experienced. Updated information on the safety and initial PK analyses will be presented. No significant financial relationships to disclose.

HIV-associated bladder cancer: diagnosis and management

Chronic HIV infection has been associated with an increased incidence of non AIDS-defining cancers. To date, only a limited number of cases of bladder cancer have been reported in association with HIV infection. Therefore, the aim of this study was to investigate a series of HIV-associated bladder cancer cases.
