Incidence and survival for oropharynx and non-oropharynx head and neck cancers among veterans living with HIV.

ABSTRACT:

Background

People living with HIV/AIDS (PLWH) have an excess risk for head and neck squamous cell carcinoma (HNSCC) compared to the general U.S. population, but little is known about HIV-specific risk factors associated with the incidence and outcomes HNSCC. We aim to identify clinical and HIV-specific risk factors associated with oropharyngeal and non-oropharyngeal HNSCC incidence and outcomes separately.

Methods

We constructed a retrospective cohort study of 45,052 PLWH aged 18 or above from the national Veteran Affairs (VA) Corporate Data from 1999 to 2015. We extracted demographic data and risk factor information, including history of alcohol abuse, smoking, CD4 count (cells/?l), and percent of follow-up time with undetectable HIV viral load as time-updated variables. We calculated the age-standardized incidence rates of oropharyngeal and non-oropharyngeal HNSCC and estimated adjusted hazard ratios (HR). We also examined overall survival using Kaplan-Meier curves and adjusted HR.

Results

The standardized incidence rate of oropharyngeal and non-oropharyngeal HNSCC in this veteran cohort of PLWH is 23.0 (95% confidence intervals (CIs): 17.1-28.9) and 55.4 (95% CI: 46.5-64.3) per 100,000 person-years, respectively. Nadir CD4 count ?200 was associated with an increased risk of non-oropharyngeal HNSCC (HR: 1.78; 95% CI: 1.31-2.30 vs >200). Five-year overall survival of OPSCC (37.0%) was significantly lower than non-oropharyngeal HNSCC (49.1%).

Conclusions

PLWH who receive care in the VA had higher age-adjusted HNSCC incidence rates than reported in the general population, suggesting that HIV and immunosuppression play a role. Additional studies should be conducted to study the interaction between HPV and HIV.

Project description:BackgroundNon-AIDS-defining cancers (NADCs) are now becoming a rising cause of morbidity among people living with HIV (PLHIV) in the highly active antiretroviral therapy (HAART) era. We conducted a systematic review and meta-analysis to estimate the summary risk of incidence and mortality of a wide range of NADCs among PLHIV compared with the general population.MethodsThis systematic review and meta-analysis was registered in the PROSPERO (registration number CRD42020222020). We searched PubMed, EMBASE, Cochrane library, and Web of Science for relevant studies published before Jan 24, 2022. Cohort or registry linkage studies comparing the incidence or mortality of individual NADCs in PLHIV with that in the general population were included. Studies simply reporting outcomes of cancer precursor lesions or combined NADCs were excluded. We calculated pooled standardised incidence (SIRs) and standardised mortality ratios (SMRs) and their 95% confidence intervals (CIs) using random-effects models, and used robust variance estimation to account for non-independence in study-level effect sizes.FindingsWe identified 92 publications arising from 46 independent studies including 7 articles out of 7 studies from developing countries. Among the 40 types of NADCs investigated, all of the 20 infection-related NADCs, cancers related with human papillomavirus infection in particular, and half of the 20 non-infection-related NADCs occurred in excess in PLHIV compared with the general population. This risk pattern was consistent in most WHO regions and in both high-income and low-and middle-income countries. The increased SIRs for various NADCs were more evident among PLHIV with advanced immunodeficiency, and was explored by HIV transmission route, and use of HAART. PLHIV had increased mortality for anal cancer (SMR 124·07, 95% CI 27·31-563·72), Hodgkin lymphoma (41·03, 2·91-577·88), liver cancer (8·36, 3·86-18·11), lung cancer (3·95, 1·52-10·26), and skin melanoma (3·95, 1·28-12·2).InterpretationPLHIV had increased incidence and mortality for a wide spectrum of NADCs. Primary prevention and effective treatment for NADCs in this population is urgently needed.FundingNatural Science Foundation of China Excellent Young Scientists Fund, Natural Science Foundation of China International/Regional Research Collaboration Project, National Science and Technology Major Project of China, Sanming Project of Medicine in Shenzhen, High Level Project of Medicine in Longhua, Shenzhen, Shenzhen Science and Technology Innovation Commission Basic Research Program, Special Support Plan for High-Level Talents of Guangdong Province, the Guangzhou Basic Research Program on People's Livelihood Science and Technology, the National Natural Science Foundation of China.
