Delaying age at first sexual intercourse provides protection against oral cavity cancer: a mendelian randomization study. Front Oncol 2024; 14:1361527. [PMID: 38699645 PMCID: PMC11063229 DOI: 10.3389/fonc.2024.1361527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 04/01/2024] [Indexed: 05/05/2024] Open
Abstract
Aim To investigate whether age at first sexual intercourse could lead to any changes in the risk of oral cavity cancer. Methods A two-sample mendelian randomization was conducted using genetic variants associated with age at first sexual intercourse in UK biobank as instrumental variables. Summary data of Northern American from a previous genome-wide association study aimed at oral cavity cancer was served as outcome. Three analytical methods: inverse variance-weighted, mendelian randomization Egger, and weighted median were used to perform the analysis, among which inverse variance-weighted was set as the primary method. Robustness of the results was assessed through Cochran Q test, mendelian randomization Egger intercept tests, MR PRESSO, leave one out analysis and funnel plot. Results The primary analysis provided substantial evidence of a positive causal relationship age at first sexual intercourse and the risk of oral cavity cancer (p = 0.0002), while a delayed age at first sexual intercourse would lead to a decreased risk of suffering oral cavity cancer (β = -1.013). The secondary outcomes confirmed the results (all β < 0) and all assessments supported the robustness, too (all p > 0.05). Conclusion The study demonstrates that a delayed sexual debut would provide protection against OCC, thus education on delaying sexual intercourse should be recommended.

Association between sexual behaviour and head and neck cancer in the French West Indies: a case-control study based on an Afro-Caribbean population. BMC Cancer 2023; 23:407. [PMID: 37147593 PMCID: PMC10163737 DOI: 10.1186/s12885-023-10870-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Accepted: 04/20/2023] [Indexed: 05/07/2023] Open
Abstract
BACKGROUND Worldwide, a significant proportion of head and neck cancers is attributed to the Human papillomavirus (HPV). It is imperative that we acquire a solid understanding of the natural history of this virus in head and neck squamous cell carcinoma (HNSCC) development. Our objective was to investigate the role of sexual behaviour in the occurrence of HNSCC in the French West Indies. Additionally, we evaluated the association of high risk of HPV (Hr-HPV) with sexual behaviour in risk of cancer. METHODS We conducted a population-based case-control study (145 cases and 405 controls). We used logistic regression models to estimate adjusted odds-ratios (OR), and their 95% confidence intervals (CI). RESULTS Compared to persons who never practiced oral sex, those who practiced at least occasionally had a lower HNSCC risk. First sexual intercourse after the age of 18 year was associated with a 50% reduction of HNSCC risk, compared to those who began before 15 years. HNSCC risk was significantly reduced by 60% among persons who used condoms at least occasionally. The associations for ever condom use and oral sex were accentuated following the adjustment for high-risk HPV (Hr-HPV). Oral Hr-HPV was associated with several sexual behaviour variables among HNSCC cases. However, none of these variables were significantly associated with oral HPV infections in the population controls. CONCLUSION First intercourse after 18 years, short time interval since last intercourse and ever condom use were inversely associated with HNSCC independently of oral Hr-HPV infection. Sources of transmission other than sexual contact and the interaction between HPV and HIV could also play a role in HNSCC etiology.

Abstract
The objective of this study was to develop and validate an App for identifying risk factors for oral cancer. To this end, we developed an App (OCS: Oral Cancer Screening) with predictors of Oral Cancer (OC) and algorithm assembly to estimate the risk of its development. METHODOLOGY Simulated clinical cases were designed so that 40 professionals with expertise in oral diagnostics could validate the algorithm and test its usability (SUS: System Usability Score) and acceptability (TAM: Technology Acceptance Model). Cronbach's alpha coefficient, Friedman/Dunn tests, and Spearman correlation evaluated the SUS and TAM scales. ROC curve was plotted to estimate the cutoff point of the algorithm in suggesting a high risk for OCS of the simulated cases. Chi-square and Fisher's exact tests were additionally used (p<0.05, SPSS v20.0). RESULTS Professionals with expertise in oral diagnosis had usability of 84.63±10.66 and acceptability of 84.75±10.62, which correlated positively (p<0.001, r=0.647). Acting in clinical areas of dentistry (p=0.034) and history of performing OC risk factor orientation (p=0.048) increased acceptability while acting in higher education increased usability (p=0.011). The cutoff point suggested by the App after validation of the simulated clinical cases showed high sensitivity of 84.8% and lower specificity of 58.4%. CONCLUSION The OCS was effective and with adequate sensitivity, usability, and acceptability and may contribute to the detection of early oral lesions.

Abstract
Recent trends have shown a dramatic rise in the incidence of oropharyngeal squamous cell carcinoma strongly associated with high-risk human papillomavirus (HPV) of type 16. The genetic variability of HPV16 has been extensively studied in cervical cancer but there are very limited published data concerning the genetic variations of this HPV type in oropharyngeal cancer. In the present study, the genetic variations of HPV16 E6 gene sequences originated from a small cohort of Greek patients diagnosed with oropharyngeal cancer were assessed. The vast majority of the sequences clustered within the European variant branch. The T350G variation was found to be the predominant one. This finding may indicate the need for further studies that could explain the possible impact of this variant in the pathomechanisms of oropharyngeal cancer.

PUBLIC HEALTH IN PRACTICE 2022; 3:100239. [PMID: 36101754 PMCID: PMC9461587 DOI: 10.1016/j.puhip.2022.100239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 02/16/2022] [Accepted: 02/21/2022] [Indexed: 11/21/2022] Open
Abstract
Objectives Public understanding of human papillomavirus (HPV)-associated oropharyngeal cancer (OPC) is minimally understood. Therefore uncovering communication gaps between the public and healthcare professionals regarding this disease is vital. Social media provide an unobtrusive way to understand public perception about health issues. Study design Computer-assisted quantitative content analysis. Methods Tweets about HPV-associated OPC (N = 3,112) were collected for 40 weeks using the standard real-time streaming Application Programming Interface (API). The collection of tweets was not limited to one specific geographic location but worldwide. All tweets were entered into nVivo 12.0 to conduct computer-assisted quantitative content analysis. We used an inductive method to develop a coding scheme and examined the frequency of specific keywords, terms, and phrases in texts. Results Findings show that (a) the majority of discourse on Twitter focused on risk factors and prevention with little information on diagnosis, treatment, and prognoses; (b) many tweets promoted HPV vaccination among boys and emphasized the risk of HPV-associated OPC among males; (c) the role of dental care professionals in the prevention and detection of OPC minimally appeared; (d) the public referred to OPC as oral cancer, head and neck cancer, or throat cancer; and (e) health organizations in New Zealand, Australia, and the United Kingdom led the discussion on HPV-associated OPC on Twitter. Conclusions The current study unravels the utility of social media data and data mining techniques in understanding public perception and understanding of HPC-associated OPC. The outcomes from the current study provide baseline knowledge of where communication gaps exist in terms of HPV-associated OPC, without which the planning of potential interventions and much-needed social media-based campaigns cannot be effectively undertaken.

Abstract
PURPOSE Although rates of sexually transmitted infections (STIs) and human papillomavirus (HPV)-related head and neck cancers associated with oral sex are increasing, less than 10% of youths report using protection. This study aims to assess youths' knowledge and perceptions of oral sex risk and barriers to protection use. METHODS Our study uses MyVoice, a national text message poll of youths aged 14-24 years. Four open-ended probes were fielded to 1,215 youths in March 2019. Qualitative data were analyzed using thematic analysis and quantitative data were summarized with descriptive statistics. RESULTS Nine hundred and nine youths responded to the survey (relative risk [RR]=74.8%). Youths' responses regarding why protection is frequently not used centered around: lack of education (22.4%), no perceived STI risk (19.8%), decreased pleasure (19.3%), and no pregnancy risk (15.7%). Youths believed that comprehensive education (53.7%), normalization in popular culture and media (19.1%), increased access to protection (15%), and improved protection options (10.5%) would increase protection use during oral sex. CONCLUSION Youths demonstrated limited knowledge of the risks of oral sex, dissatisfaction with current protection options, and a need for normalization in popular culture. Programs developed with youths in mind may be able to successfully increase protection use and decrease rates of STI transmission and oral sex-related HPV head and neck cancer.VISUAL ABSTRACT.

Abstract
BACKGROUND Case-control studies from the early 2000s demonstrated that human papillomavirus-related oropharyngeal cancer (HPV-OPC) is a distinct entity associated with number of oral sex partners. Using contemporary data, we investigated novel risk factors (sexual debut behaviors, exposure intensity, and relationship dynamics) and serological markers on odds of HPV-OPC. METHODS HPV-OPC patients and frequency-matched controls were enrolled in a multicenter study from 2013 to 2018. Participants completed a behavioral survey. Characteristics were compared using a chi-square test for categorical variables and a t test for continuous variables. Adjusted odds ratios (aOR) were calculated using logistic regression. RESULTS A total of 163 HPV-OPC patients and 345 controls were included. Lifetime number of oral sex partners was associated with significantly increased odds of HPV-OPC (>10 partners: odds ratio [OR], 4.3 [95% CI, 2.8-6.7]). After adjustment for number of oral sex partners and smoking, younger age at first oral sex (<18 vs >20 years: aOR, 1.8 [95% CI, 1.1-3.2]) and oral sex intensity (>5 sex-years: aOR, 2.8 [95% CI, 1.1-7.5]) remained associated with significantly increased odds of HPV-OPC. Type of sexual partner such as older partners when a case was younger (OR, 1.7 [95% CI, 1.1-2.6]) or having a partner who had extramarital sex (OR, 1.6 [95% CI, 1.1-2.4]) was associated with HPV-OPC. Seropositivity for antibodies to HPV16 E6 (OR, 286 [95% CI, 122-670]) and any HPV16 E protein (E1, E2, E6, E7; OR, 163 [95% CI, 70-378]) was associated with increased odds of HPV-OPC. CONCLUSION Number of oral sex partners remains a strong risk factor for HPV-OPC; however, timing and intensity of oral sex are novel independent risk factors. These behaviors suggest additional nuances of how and why some individuals develop HPV-OPC.

Abstract
A significant subset of carcinomas developed in the head and neck (H&NCs) are associated with specific human papillomaviruses (HPV) genotypes. In particular, 40–60% of oropharyngeal carcinoma cases are linked to HPV. Epidemiological studies have demonstrated that HPV oral infections are predominantly sexually transmitted and are more frequent among men (10–18%) than women (3.6–8.8%). Although there is a large diversity of HPV genotypes associated with H&NCs, HPV16 lineage represents 83% of the reported cases. The prognostic value of HPV as a biological parameter is well recognized. However, the use of HPV DNA as a diagnostic and/or predictive marker is not fully developed. Recent data reporting the physical state of the HPV genome in tumors have shown that HPV DNA integration into the tumor cell genome could lead to the alteration of cellular genes implicated in oncogenesis. Most importantly, HPV DNA corresponds to a tumor marker that can be detected in the blood of patients. Profile of the HPV DNA molecular patterns in tumor cells using New Genome Sequencing-based technologies, allows the identification of highly specific tumor markers valuable for the development of innovative diagnostic and therapeutic approaches. This review will summarize recent epidemiological data concerning HPV-associated H&NCs, the genomic characterization of these tumors, including the presence of HPV DNA in tumor cells, and will propose perspectives for developing improved care of patients with HPV-associated H&NCs, based on the use of viral sequences as personalized tumor markers and, over the longer term, as a therapeutic target.

Abstract
AbstractHead-and-neck cancers pose a serious economic burden, with most countries investing significant resources to reduce the incidence, primarily focusing on understanding addictive etiologies. The traditional literature focused on tobacco and alcohol use, with few studies on contemporary factors such as e-cigarette, waterpipe smoking, and human papillomavirus. This article attempts to collate and present an update on the globally identified etiologic factors.The aim of this study was to identify and review the addictive etiologic factors causing head-and-neck cancers.An electronic search was performed on Medline, Embase, and Google Scholar to identify the etiologies causing head-and-neck cancers and narrowed down on those driven by addiction. Further, we identified their constituents, mechanism of action, and the risks attributable to various forms of products.Substances identified included smoked and chewed tobacco, alcohol, mate, marijuana, areca nut and betel quid, and viruses. An alarming majority of youth are now utilizing these substances. Furthermore, migrant movements have led to the spread of traditional practices across the regions, especially from the Asian subcontinent.Ironically, despite modern advances and technology, we still see that a large proportion of population succumb to these cancers, emphasizing the need for more effective and targeted policies to combat this menace at the grassroots level.

Abstract
The oropharynx has become the leading primary site for Human Papilloma Virus (HPV)-associated head and neck cancer. HPV positive oropharyngeal squamous cell carcinoma (HPV+ OSCC) has emerged as an epidemic not easily recognized by many physicians, resulting in delays in diagnosis and management. HPV+ OSCC traditionally refers to younger, healthier patients with high economic status and high-risk sexual behavior and is related to improved prognosis. De-intensification strategies are being evaluated in ongoing clinical trials and if validated, might help spare severe morbidity associated with current cisplatin-based chemoradiotherapy, which is the standard of care for all patients with locally advanced head and neck cancer. On the other hand, whether HPV status represents an important prognostic factor for non-oropharyngeal sites remains to be elucidated.

Reprod Health 2019; 16:48. [PMID: 31060573 PMCID: PMC6501425 DOI: 10.1186/s12978-019-0722-9] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2018] [Accepted: 04/15/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Oral and anal sexual behaviours are increasingly reported among adolescents and adults reporting heterosexual sex in peer-reviewed journals in high income countries, but less is known about these behaviours in low and middle-income countries, especially in sub-Saharan Africa. The aim of this systematic review is to describe the prevalence of, and motivations for, oral and anal sex among adolescents and adults reporting heterosexual sex in sub-Saharan Africa. METHODS A systematic review of published articles that reported oral and or anal sex in sub-Saharan Africa was conducted from seven databases up to and including 30th August 2018. RESULTS Of 13,592 articles, 103 met the inclusion criteria. The prevalence of reporting ever practising oral sex among adolescents, university students and a combined population of adolescents/adults ranged from 1.7-26.6%, 5.0-46.4% and 3.0-47.2% respectively. Similarly, prevalences of reported ever practising anal sex ranged from 6.4-12.4% among adolescents, 0.3-46.5% among university students and 4.3-37.8% amongst combined population of adolescents and adults. Higher prevalences of oral and anal sex were reported among populations at high-risk for sexually transmitted infections and HIV and university students and, in most studies, both behaviours were more commonly reported by males than females. Heterosexual oral and anal sexual acts were associated with some high-risk behaviours such as inconsistent condom use and multiple sexual partners. CONCLUSION Reported oral and anal sex between men and women are prevalent behaviours in sub-Saharan Africa. Health professionals and policy makers should be aware of these behaviours and their potential associated health risks.

Cancer Med 2019; 8:1908-1918. [PMID: 30821126 PMCID: PMC6488137 DOI: 10.1002/cam4.2039] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Revised: 01/09/2019] [Accepted: 01/29/2019] [Indexed: 12/14/2022] Open
Abstract
The prevalence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing globally while the prevalence of other head and neck cancers is decreasing. The most likely reasons for this are a decreasing influence of smoking and the growing relevance of infections with the human papilloma virus (HPV) as a risk factor. A rise in the HPV‐attributable fraction (HPV‐AF) of OPSCC has been observed in many countries, yet a comprehensive review of prevalence rates and trends in Germany is lacking. To determine the current HPV‐AF of OPSCC in Germany and to assess whether it has changed during the last decades, we performed a systematic literature review. We screened Medline and EMBASE for studies that reported the tumor HPV status of newly diagnosed OPSCC patients treated at medical centers in Germany by testing for both HPV DNA and p16INK4a overexpression to confirm involvement of HPV in tumorigenesis. Out of 287 screened studies, 14 studies with data from a total of 1819 OPSCC patients treated between 1988 and 2015 were included in the data synthesis. The reported average HPV‐AF varied considerably between the studies, ranging from 11.5% (1988‐2008) to 55.0% (2004‐2009). Two of the included studies did not only provide the HPV‐AF for the entire observed calendar period but also for separate years, allowing to more accurately assess changes over time. These studies reported increases in the HPV‐AF from 21% in 2000 to 53% in 2015 and from 38% in 2004 to 71% in 2013, respectively.

[PMID: 30650137 PMCID: PMC6334946 DOI: 10.1371/journal.pone.0210398] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Accepted: 12/21/2018] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Sexually transmitted infections can be spread through oral and anal heterosexual sex. There are few data on these practices in Sub-Saharan Africa. We analyzed the prevalence of heterosexual oral and anal sex among HIV Voluntary Counseling and Testing (VCT) attendees in Kinshasa and the associated sociodemographics, perceptions and behavioral factors. METHODS OKAPI (Observational Kinshasa AIDS Prevention Initiative) prospective cohort study. It evaluates the VCT impact on HIV-related knowledge and behaviors at 6 and 12-month follow-up. Since April 2016 until April 2018, 797 persons aged 15-59 years were HIV tested and replied to a baseline interview, including information about anal and oral sex. Descriptive, bi- and multivariate analyses were performed using baseline data. RESULTS Among 718 sexually active participants reporting heterosexual sex, 59% had had oral sex, 22% anal sex and 18% both practices. Among participants reporting "not" having had sex, 6% reported oral sex, 3% anal sex and 1% both. Oral sex was associated with a daily use of the Internet/mobile phone, perceiving low community HIV risk, reporting HIV-related behaviors (multiple partners, inconsistent condom use, anal, paid and forced sex) and having been pregnant. Being married-monogamous was inversely associated with oral sex. Anal sex was directly associated with having other risk sexual behaviors. CONCLUSIONS Oral and anal sex were common among people reporting heterosexual sex in Kinshasa. Perceiving a low community HIV risk and having other sexual risk behaviors are associated with these practices, which are commonly not considered as risky despite their strong association with HIV/STIs. They need to be considered when designing preventive strategies in Kinshasa.

Abstract
With every passing year, more and more studies and observations demonstrate growing incidence of oral cancer, a decrease in patients' age, and an increasing number of epidemiological factors. The aim of the study was to determine the level of awareness among undergraduate and graduate university students regarding the incidence of oral cancer linked with viral infections and high-risk sexual behavior, including oral sex. Self-administered questionnaire-based survey was carried out among 196 Polish students aged 19 to 25 years. It was found that the young adults understood the meaning of human papillomavirus (HPV), but associated it only with the squamous cell carcinoma of the cervix. A total of 43.4% did not realize that there was any correlation between HPV infection and the development of oral cancer. The students who were aware of this correlation constituted 40.3% of the total. The majority of the participants, that is, 82 subjects (41.8%), did not associate the occurrence of malignant neoplasms of the oral cavity with oral sex. The study group did not present adequate awareness of the fact that occurrence of oral cancer may be associated with high-risk sexual behaviors. Knowledge of oral cancer was not significantly related to the level of university education (P < .005).

Abstract
Human papillomavirus (HPV) has been recently recognised as a carcinogenic factor for a subset of head and neck cancers (HNC). In Europe, France has one of the highest incidence rates of HNC. The aim of this study is to explore changes in HNC incidence in France, potentially in relation with infection by HPV. HNC were classified into two anatomical groups: potentially HPV-related and HPV-unrelated. Trends over the period 1980-2012 were analysed by an age-period-cohort model based on data from eleven French cancer registries. Among men, the age-standardised incidence rate (ASR) of HNC decreased in both groups, but less so for HPV-related sites as compared to unrelated sites, especially in recent years (annual percentage change [APC] over the period 2005-2012: -3.5% vs. -5.4%). Among women, the ASR increased in both groups, but more rapidly for HPV-related as compared to unrelated sites (APC over the period 2005-2012: +1.9% vs. -0.4%). This preferential growth of HPV-related versus unrelated HNC was observed in the cohorts born from 1930 to 1935. The differences in trends between possible HPV-related and HPV-unrelated sites suggest an increasing incidence of HNC due to HPV infection. The difference was less marked in men as compared to women, most likely because of a higher contamination in the HPV-related group by cancers due to tobacco or alcohol consumption. The pattern observed is consistent with observations made in other countries, with studies of HPV prevalence in HNC and the evolution of sexual behaviour in France.

Abstract
INTRODUCTION HPV attributable cancers are the second most common infection-related cancers worldwide, with much higher burden in less developed regions. There are currently no country-specific estimates of the burden of these cancers in Nigeria just like many other low and middle income countries. METHODS In this study, we quantified the proportion of the cancer burden in Nigeria that is attributable to HPV infection from 2012 to 2014 using HPV prevalence estimated from previous studies and data from two population based cancer registries (PBCR) in Nigeria. We considered cancer sites for which there is strong evidence of an association with HPV infection based on the International Agency for Research on Cancer (IARC) classification. We obtained age and sex-specific estimates of incident cancers and using the World Standard Population, we derived age standardized incidence (ASR) rates for each cancer type by categories of sex, and estimated the population attributable fractions (PAF). RESULTS The two PBCR reported 4336 new cancer cases from 2012 to 2014. Of these, 1627 (37.5%) were in males and 2709 (62.5%) in females. Some 11% (488/4336) of these cancers were HPV associated; 2% (38/1627) in men and 17% (450/2709) in women. Of the HPV associated cancers, 7.8% occurred in men and 92.2% in women. The ASRs for HPV associated cancers was 33.5 per 100,000; 2.3 and 31.2 per 100,000 in men and women respectively. The proportion of all cancers attributable to HPV infection ranged from 10.2 to 10.4% (442-453 of 4336) while the proportion of HPV associated cancers attributable to HPV infection ranged from 90.6% to 92.8% (442-453 of the 488 cases). In men, 55.3% to 68.4% of HPV associated cancers were attributable to HPV infection compared to 93.6% to 94.8% in women. The combined ASR for HPV attributable cancers ranged from 31.0 to 31.7 per 100,000. This was 1.4 to 1.7 per 100,000 in men and 29.6 to 30.0 per 100,000 in women. In women, cervical cancer (n=392, ASR 28.3 per 100,000) was the commonest HPV attributable cancer, while anal cancer (n=21, ASR 1.2 per 100,000) was the commonest in men. CONCLUSIONS HPV attributable cancers constitute a substantial cancer burden in Nigerian women, much less so in men. A significant proportion of cancers in Nigerian women would be prevented if strategies such as HPV DNA based screening and HPV vaccination are implemented.
