Are sex and gender considered in head and neck cancer clinical studies? NPJ Precis Oncol 2023; 7:84. [PMID: 37679495 PMCID: PMC10484986 DOI: 10.1038/s41698-023-00439-z] [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: 04/17/2023] [Accepted: 08/14/2023] [Indexed: 09/09/2023] Open
Abstract
We analyzed the inclusion of sex and/or gender (S/G) in Head and Neck Cancer (HNC) clinical studies, through inspecting ClinicalTrials.gov (AACT) and the mention of Human Papilloma Virus (HPV) on a specific subgroup, namely oral cavity, larynx and oropharynx. Only 5% of HNC studies mention S/G as a planned analytical variable. Proportionally more observational studies treated S/G as an analytical variable than interventional studies (10% vs 5%, P-value ≤ 0.001), 8% of studies that mentioned S/G involved more than 100 subjects while 4% less than 100 (P-value ≤ 0.001). In randomized protocols, S/G was mentioned more in studies with a planned sample of more than 100 patients and including HPV status (P-value < 0.05). Small controlled studies have lower mention of S/G as an analytical variable than uncontrolled studies (4% and 10%, respectively among studies with less than 100 subjects). Significantly greater mention of S/G as an analytical variable is observed in controlled and randomized studies with a sample size greater than 100 subjects. HPV was mentioned in only 18% of oral cavity-larynx-oropharynx studies. Interventional studies do not regularly account for S/G during HNC study design. Thus, although fundamental, in studies concerning HNC the S/G variable is often not considered. In trials published in scientific journals (P-value = 0.01) and in more recent clinical trials (P-value = 0.002), S/G is taken more into account suggesting an increasing awareness on its importance. However, the need to systematically include S/G in study design clearly emerges, to better highlight sex-related differences in disease incidence and prognosis and best imbue science and medicine with the proper biological and cultural differences.

Abstract
Despite decades of research, cancer continues to be a major global health concern. In recent years, the role played by microorganisms in the development and progression of cancer has come under increased scrutiny. The aim of the present review is to highlight the main associations between members of the human oral microbiota and various cancers. The PubMed database was searched for available literature to outline the current state of understanding regarding the role of the oral microbiota and a variety of human cancers. Oral squamous cell carcinoma (OSCC) is associated with carriage of a number of oral bacteria (e.g., Porphyromonas gingivalis, Fusobacterium nucleatum, Streptococcus sp.), certain viruses (e.g., human papilloma virus, human herpes virus 8, herpes simplex virus 1 and Epstein-Barr virus) and yeast (Candida albicans). Moreover, members of the oral microbiota are associated with cancers of the esophagus, stomach, pancreas, colon/rectum and lung. Furthermore, the present review outlines a number of the carcinogenic mechanisms underlying the presented microbial associations with cancer. Such information may one day help clinicians to diagnose neoplastic diseases at earlier stages and prescribe treatments that take into account the possible microbial nature of carcinogenesis.

Abstract
Oral cancer is frequently associated with smoking, alcohol consumption, and betel quid chewing, which are common harmful behaviors observed in certain cohorts of the Taiwanese population. Some reports have explored the potential therapeutic effect of certain herbal remedies on cancer treatments and the outcomes thereof. However, supportive evidence regarding the specific use of traditional Chinese medicine (TCM) in oral cancer treatment is lacking and deserves further investigation. This study measured the use of TCM therapies for oral cancer in a Taiwanese population-based retrospective longitudinal cohort study. The Taiwan National Health Insurance Research Database was utilized to conduct this study. The study population was limited to oral cancer patients diagnosed between 2000 and 2009, which were followed up for at least 5 years. Therapeutic strategies investigated included acupuncture and the Chinese herbs and formula used. Additionally, the frequency of TCM treatment visits, total medical costs, and all-cause mortality were also analyzed. Between 2000 and 2009, a total of 951 patients were diagnosed with various oral cancers. 13.7% of the diagnosed patients utilized TCM treatment measures. The majority of the patients were males. The top 3 common single herbs used were Xuán shēn (Radix Scrophulariae), Shí hú (Herba Dendrobii), and Mài mén dōng (Ophiopogon Japonicus). Then, Gān lù yǐn, Zhī bǎi dì huáng wán, and Sàn zhǒng kuì jiān tāng were the most frequently used herbal formulas. The survival probability was higher in TCM users when compared to non-TCM users in 5- and 12-year all-cause mortality (P < .05). This study explored the use of TCM therapies in oral cancer patients and identified essential information regarding the specifics of conventional herbal medicine used, affiliated medical costs, survival probability, and common symptoms observed in Taiwanese oral cancer patients.

Abstract
Oral cavity squamous cell carcinoma (OCSCC) is one of the most common head and neck cancers worldwide. It is well known that risk factors for OCSCC include tobacco and excess alcohol consumption. However, in recent years, OCSCC incidence has been increasing in patients without these traditional risk factors. The cause of this increase is unclear and various genetic, environmental, and infectious factors have been hypothesized to play a role. Additionally, there are expert opinions that oral cancer in non-smoking, non-drinking (NSND) patients have a distinct phenotype resulting in more aggressive disease presentation and poorer prognosis. In this review, we summarize the current state of knowledge for oral cavity cancer in patients without traditional risk factors.

Abstract
BACKGROUND Persistent oral human papillomavirus (HPV) infection is a risk factor for oropharyngeal squamous cell carcinoma (OPSCC). Indigenous Australians have a higher rate of OPSCC than non-Indigenous Australians. Risk factors for oral HPV persistence among Indigenous Australians are poorly understood. METHODS Participants provided information on socio-demographic characteristics, health-related behaviours including tobacco and alcohol use and sexual history. Participants additionally provided saliva samples for microbial genotyping. Negative log binomial regression models were used to evaluate indicators on incident, persistent and cleared oral HPV infection at 12 months follow-up. RESULTS Of the 1,011 participants recruited at baseline, 321 (35.3%) testing positive for any oral HPV infection. At 12-month follow up, saliva samples were obtained from 743 participants (73.5%). Among the 584 participants, 24 (42.6%) had no oral HPV infection at both time points, 130 (22.2%) had new (incident) oral HPV infection at 12 months, 130 (22.2%) had persistent oral HPV infection (i.e. present at both baseline and 12-months), and 75 (12.8%) had oral HPV infection clearance from baseline to 12-months. Rural location of residence and ever received oral sex were significantly associated with persistence of oral HPV infection. CONCLUSIONS The incidence of oral HPV infection at both baseline and 12-month follow-up was high. IMPACT There are currently no studies available which have assessed oral HPV infection incidence, persistence and clearance amongst Indigenous populations in Australia or even at a global level. The study has been able to identify risk factors associated with potential malignant changes in the oropharynx among Indigenous Australians.

Abstract
BACKGROUND Human tongue squamous cell carcinoma (TSCC) is the most common oral cancer with the highest human papillomavirus (HPV) infection rate in oral cancer. The purpose of this study was to research the correlation between HPV and TSCC. METHOD Plasmid pEGFP/HPV16 E6E7 and plasmid pEGFP/no HPV16 E6E7 were constructed. TSCC cell lines SCC9 and SCC15 were infected by liposome transfection and would be highly selected by antibiotic. Fluorescence imaging, PCR, and Western blot were used to detect the expression of HPV16 E6E7 in cells. The biological characteristics were detected by CCK-8, wound healing assay, qRT-PCR, and Western blot. RESULT TSCC cell lines transfected with HPV16 E6E7 gene were successfully established and identified. And the proliferation and migration ability of the TSCC cell lines infected with HPV16 E6E7 gene were significantly stronger than that of the blank group. CONCLUSION TSCC cell lines infected with HPV16 E6E7 with significantly higher ability of proliferation and migration were more malignant than those not infected with HPV16 E6E7.

Abstract
Oral submucous fibrosis (OSF) is a collagen deposition disorder that affects a patient’s oral function and quality of life. It may also potentially transform into malignancy. This review summarizes the risk factors, pathogenic mechanisms, and treatments of OSF based on clinical and bio-molecular evidence. Betel nut chewing is a major risk factor that causes OSF in Asia. However, no direct evidence of arecoline-induced carcinogenesis has been found in animal models. Despite identification of numerous biomarkers of OSF lesions and conducting trials with different drug combinations, clinicians still adopt conservative treatments that primarily focus on relieving the symptoms of OSF. Treatments focus on reducing inflammation and improving mouth opening to improve a patient’s quality of life. In conclusion, high-quality clinical studies are needed to aid clinicians in developing and applying molecular biomarkers as well as standard treatment guidelines.

Abstract
INTRODUCTION Oral human papillomavirus (HPV) and oropharyngeal cancer prevalence are increasing, particularly in men. Raising greater awareness of male HPV disease is perceived as an important intervention strategy. This study investigated the effectiveness of HPV education on adolescents' perception of HPV disease and the impact of HPV vaccination on their sexual health. METHODS An HPV questionnaire was completed by 357 UK-based adolescents, aged 12-13 years. RESULTS Most adolescents knew HPV causes cervical cancer and HPV vaccination prevents this. A minority acknowledged HPV causes other genital cancers, with under one-fifth knowing HPV causes genital warts. Adolescents' awareness of HPV transmission activities were limited. There was very poor awareness of oral HPV infection or HPV-induced oropharyngeal cancer. Half of the participants stated HPV vaccination reduced their concerns about sexually transmitted infection contraction. Over half the males said they may take more sexual risks following vaccination, while a similar proportion of females did not expect their partner to take more risks. CONCLUSIONS Adolescents had little awareness of male HPV infection and the role HPV vaccination can play in preventing these diseases. With variable rates of HPV vaccination uptake in males reported worldwide, this study indicates that in the UK greater emphasis on male HPV disease within educational information is required, to raise better awareness of how HPV affects both genders. As both genders preferred to receive education via healthcare professionals, educating a wider range of healthcare professionals on oral HPV could help facilitate awareness of HPV's role in head and neck cancer.

Abstract
Background The main objective of this study was to estimate the prevalence of human papillomavirus-DNA (HPV-DNA) in the saliva of sexually active women with HPV-related cervical intraepithelial neoplasias (CIN) and compare the findings with a healthy control group. The secondary objectives were: 1) to determine the concordance between genital and oral HPV types in sexually active women with HPV-related CIN; 2) to analyze whether sexual habits influence the presence of HPV-related CIN; 3) to determine whether sexual habits influence the presence of oral HPV.
Material and Methods Saliva samples were collected from 100 sexually active women, 50 with HPV-related CIN and 50 healthy subjects presenting normal cytology. PCR assay was used to detect HPV-DNA.
Results The prevalence of oral HPV infection in saliva samples was 14% in women with HPV-related CIN, while in the healthy group it was 12%, without statistically significant difference (p =0.766). As for the concordance between genital and oral HPV types in women with HPV-related CIN, concordance was only observed for HPV-16, whereby among 22 women with genital HPV-16, only one (4.54%) also presented oral HPV-16. Regarding the possible influence of sexual habits on the presence of cervical pathology and presence of oral HPV, it was found that marital status, age at first intercourse, number of lifetime sexual partners, and condom use are related with the presence of cervical pathology (p<0.001; p=0.017; p=0.002; and p <0.001, respectively); condom use was also found to be related to the presence of oral HPV (p<0.001).
Conclusions The prevalence of HPV-DNA in the saliva of sexually active women with HPV-related CIN is similar to healthy women. The concordance between genital and oral HPV types is low. Both the presence of cervical pathology and the presence of oral HPV are related to sexual habits. Wider sample size is required to confirm this results. Key words:Cervical intraepithelial neoplasias, HPV, saliva, cervix, cancer.

Abstract
Background Human papillomavirus (HPV) has been associated with certain types of oropharyngeal cancers and yet, the level of knowledge that dental professionals and the lay public have in terms of HPV transmission, oral sexual activities, and oral cancer development needs exploration. The aim of this study was to assess the knowledge held by practicing dental professionals as well as the lay public regarding Human Papillomavirus (HPV) transmission through oral sex and subsequent oropharyngeal cancer development. Methods Textual data were collected from a public forum with dental professionals in. Vancouver, who discussed the HPV-oral sex-oral cancer triad, and from survey data gathered from 212 lay public participants (also in Vancouver) who answered a 13-item questionnaire on the perceived risks of oral sex in terms of HPV infection and oropharyngeal cancer development. The data were analyzed statistically by age group, gender, and sexual orientation using descriptive statistics, while an ANOVA test was used to compare variation in the responses to the survey (p-value = 0.05). Results The forum engaged 46 health care professionals, many of whom were aware of the potential risks for head and neck cancer development due to HPV infection, while also questioning “how to effectively talk about HPV with patients.” The survey revealed that 34.5% of the participants believed that oral sex is an activity with no or low risk for the transmission of HPV, while 84% of participants believed the same sexual practices were of low or no-risk for HIV (Human Immunodeficiency Virus) transmission. Most participants (82%) never discussed oral sexual activities with their physicians or dentists/dental hygienists. Conclusions The general public remains mostly unaware of the potential links between HPV infection and oropharyngeal cancer. Physicians and dental providers should discuss oral sexual practice with their patients to raise awareness.

Abstract
Introduction: Oral cancer ranks third among all cancers in the Indian population with approximately 45% of call cancer cases in India being diagnosed as oral cancer, among which 20%–50% of the cases are observed to be associated with human papillomavirus (HPV) infection. Aim: This study aims to detect and evaluate the presence of p16 in oropharyngeal squamous cell carcinoma (OPSCC) patients using immunohistochemistry (IHC). Materials and Methods: This study was based on samples collected from 21 patients with primary OPSCC who were diagnosed and treated during the period of December 2017–March 2018. Inclusion criteria were complete clinicopathologic data, adequate clinical follow-up, and availability of sufficient paraffin-embedded tumor material. HPV immunoreactivity was further investigated by means of IHC using p16 as a marker. Results: IHC results revealed p16 positivity in six OPSCC cases. There was no statistically significant association of the p16 positivity of HPV with the age, gender, or site. Conclusion: Our results suggest that IHC-based detection of p16 provides a suboptimal prognostic information if not combined with detection of HPV DNA. Although p16 expression and HPV DNA infection are correlated with HPV-associated OPSCCs, neither of the tests alone is the optimal method for HPV status detection.

Abstract
BACKGROUND The incidence of human papilloma virus (HPV)-related oral cancer has recently increased worldwide. The role of dentists is of prime importance in the early detection of oral cancer which would result in a favourable outcome for the patients. The aim of the current study was to assess the knowledge, awareness and attitudes of dental students, interns and postgraduate maxillofacial residents at the University of Jordan (UJ) to different aspects of oral cancer, particularly those related to HPV. METHODS A paper-based survey was conducted at UJ among all pre-clinical dental students (pre-clinical group), clinical dental students, interns and postgraduate maxillofacial residents (clinical group). The survey included five sections comprising 29 items. The sections included questions investigating oral cancer knowledge, oral cancer screening, HPV knowledge and the ability to discuss personal topics with patients. RESULTS A total of 376 respondents out of 1052 potential participants completed at least one item of the survey (study coverage of 35.7%). Among the study participants, the pre-clinical group represented 41.2% (n = 155) and the clinical group represented 58.8% (n = 221). The majority of participants in the clinical group showed better knowledge on oral cancer potential anatomic sites, clinical presentation and possible risk factors compared to the pre-clinical group. Most participants in the clinical group (n = 195, 88.2%) correctly identified HPV as a risk factor for oral cancer development. The majority of participants in the clinical group displayed suitable attitude towards oral cancer screening despite their desire for a reliable screening device and additional training in oral cancer screening. A number of limitations in basic knowledge about HPV was noticed among participants in the clinical group particularly related to unawareness of the vaccine availability. The majority of participants in the clinical group displayed hesitancy in discussing personal topics with the patients, including the history of previous sexually transmitted infections and sexual abuse. CONCLUSIONS Gaps in knowledge regarding HPV-related oral cancer has been detected which necessitate intervention measures including curricular changes, training workshops and awareness campaigns.

Mining of Self-Organizing Map Gene-Expression Portraits Reveals Prognostic Stratification of HPV-Positive Head and Neck Squamous Cell Carcinoma. Cancers (Basel) 2019; 11:cancers11081057. [PMID: 31357501 PMCID: PMC6721309 DOI: 10.3390/cancers11081057] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 07/21/2019] [Accepted: 07/24/2019] [Indexed: 12/12/2022] Open
Abstract
Patients (pts) with head and neck squamous cell carcinoma (HNSCC) have different epidemiologic, clinical, and outcome behaviors in relation to human papillomavirus (HPV) infection status, with HPV-positive patients having a 70% reduction in their risk of death. Little is known about the molecular heterogeneity in HPV-related cases. In the present study, we aim to disclose the molecular subtypes with potential biological and clinical relevance. Through a literature review, 11 studies were retrieved with a total of 346 gene-expression data points from HPV-positive HNSCC pts. Meta-analysis and self-organizing map (SOM) approaches were used to disclose relevant meta-gene portraits. Unsupervised consensus clustering provided evidence of three biological subtypes in HPV-positive HNSCC: Cl1, immune-related; Cl2, epithelial–mesenchymal transition-related; Cl3, proliferation-related. This stratification has a prognostic relevance, with Cl1 having the best outcome, Cl2 the worst, and Cl3 an intermediate survival rate. Compared to recent literature, which identified immune and keratinocyte subtypes in HPV-related HNSCC, we confirmed the former and we separated the latter into two clusters with different biological and prognostic characteristics. At present, this paper reports the largest meta-analysis of HPV-positive HNSCC studies and offers a promising molecular subtype classification. Upon further validation, this stratification could improve patient selection and pave the way for the development of a precision medicine therapeutic approach.

Abstract
Over the last few decades, the human papillomavirus (HPV) infection has emerged as a new epidemic and become a health issue due to its involvement in several cancers affecting the cervix, the anogenital region and the oropharynx. In this review, we aim to understand and explain the distinctive features of HPV-related oropharyngeal squamous cell carcinoma based on its epidemiological data, risk factors, specific topography, HPV subtypes most frequently involved, HPV-status diagnosis, clinical behaviour, prognosis, treatment, and preventive measures. In addition, the relationship of HPV with the development of other head and neck carcinomas and benign lesions of the oral cavity will also be discussed.

Abstract
Oropharyngeal cancer is in the sixth position of cancer incidence in the world (after colorectal, breast, prostate, bladder, and cervix uteri cancer). More than 90% of them are squamous cell carcinoma. This type of cancer can originate on the lip, oral cavity, pharynx, and larynx. The risk factors associated with oropharyngeal cancer are tobacco, alcohol, and poor oral hygiene. However, other conditions, such as infection with human papilloma virus (HPV) and oral dysbiosis, are gaining prominence. Pre-malignant and malignant lesions are related to diverse factors that can be monitored by the health professional. These professionals are also in an ideal position to influence and advise patients on healthy life habits that contribute to prevent or treat metabolic-endocrine syndromes associated with the development of pre-cancerous disease and cancer located in different organs.

Abstract
Sexually transmitted infections (STIs) can impair sexual health. Surveillance and study data were used to provide an overview over STIs in Germany. We estimated 3900 new HIV diagnoses in 2015. Of newly diagnosed infections, 57% were attributed to men who have sex with men (MSM). It was further estimated that there were 3200 new HIV infections and 84,700 people living with HIV in 2015. A total of 6834 syphilis infections were recorded in 2015, which corresponds to an increase of 149% since 2009. The incidence in men was 16-times higher than in women. Of syphilis infections, 85% could be attributed to MSM. Antimicrobial resistance of gonococci against the broad-spectrum antibiotic cefixime decreased between 2014 and 2016 after a change of therapy guidelines and remained stable on a low level regarding the antibiotic ceftriaxone. After an increase of resistance against the antibiotic azithromycin to 11.3% in 2015, we observed a decreasing trend in 2016. Between 2013 and 2015, 2,355,336 chlamydia tests were reported through the chlamydia sentinel network. Of these, 92.5% of samples were from women. Uptake for screening for women <25 years was 11.3% in 2015, with 5.0% positive chlamydia tests. In a cross-sectional study among women aged 20-25 years, a prevalence of human papilloma virus (HPV) of 38.1% was observed. A total of 30.5% of 15-year-old women were vaccinated against HPV in 2014. Data suggest that STIs represent a high burden of disease. Knowledge of STI prevention should be improved by targeted education campaigns. Extending existing offers for counselling and testing through cooperation between different health sectors would improve early diagnosis and treatment of STIs.

Abstract
A subgroup of oropharyngeal squamous cell carcinomas (OSCCs) are causally linked to infection with high-risk human papillomaviruses (HR-HPVs). To evaluate the prevalence of simultaneous oral HPV infection in females with cervical high-grade squamous intraepithelial lesions (HSIL), tonsillar- and cervical smears were collected simultaneously from 73 patients and analyzed for HPV using two commercial assays, PapilloCheck (Greiner-Bio-One) and Linear Array (Roche). Only 3/73 (4.1%) tonsillar smears were HPV positive (HPV+), with HPV types 16, 35, and 45, respectively, detected by both assays (100% agreement). Concordant results were also found in 60/66 (91%) evaluable cervical smears. Of specimens, positive by both assays, typing results completely coincide in 71% (all types are identical) and partially coincide in 27% (at least one type is identical). Taken together, results of HPV detection and typing by PapilloCheck and Linear Array are highly congruent and confirm the low prevalence of HR-HPV in tonsillar smears of patients with HSIL of the uterine cervix. Our data indicate low prevalence of oropharyngeal HPV infection in patients with high-grade cervical dysplasia. The low detection rate was confirmed by using two different commercial assays with largely consistent results of HPV detection and typing, but with some variation for particular HPV types. Comparative testing of larger numbers is required to identify the HPV types prone to escape detection with particular assays.

Abstract
Background This study aims to assess, in the population of patients with oral cancer treatment, the influence on the quality of life of two protocols of dental treatment: not ruled hospital treatment versus ruled hospital treatment. Material and Methods A quasi-experimental approach justified on ethical grounds was used. A total of 41 patients were included in the control group (not ruled treatment outpatient health center) and 40 in the experimental group (ruled hospital treatment). A total of 14 questions to both groups were conducted in three stages: before starting cancer treatment, during treatment and after treatment. the proportions of positive responses in groups and different times were compared using the chi-square test. Results Based on similar situations during cancer treatment were identified as six issues favorable to the experimental group difference. This number rose to nine after finishing oncological treatment. Conclusions From our data we can confirm that planned dental treatment performed during the oral cancer treatment produces an improvement in the quality of life in patients with oral cancer.

Abstract
Background This study aims to evaluate the influence of two dental treatment protocols, outpatient non-regulated treatment versus supervised hospital treatment, on the oral health of patients undergoing oral cancer (only radiochemotherapy treatment, not surgical) treatment. Material and Methods The study used a quasi-experimental approach justified on ethical grounds. A total of 41 patients were included in the control group (outpatient non-regulated treatment) and 40 patients in the experimental group (in-hospital supervised treatment). The patients were treated only with chemotherapy (not surgical treatment was made) for oral cancer. This decision was taken by the oncology committee of the hospital without being influenced by this study. Data regarding plaque index, daily brushing habits, appearance of new cavities, need for extractions, appearance of candidiasis and use of prosthetics in both groups were collected at three points throughout the study: before starting cancer treatment, during treatment and after treatment. The values obtained using the Student’s t-test and chi-squared were compared. Results Based on similar patient backgrounds, throughout cancer treatment the intervention under study resulted in a decrease in plaque index, necessary extractions, and incidence of decay, as well as an increase in daily brushing among other improvements in oral health observed in the experimental group versus the control group. Conclusions From our data, we can confirm that supervised dental treatment performed during oral cancer treatment produced an improvement in the oral health of patients with oral cancer. Key words:Oral cancer, dental treatment, quality of life, oncology, dentistry.

Abstract
Recent studies show that the human Merkel cell polyomavirus (MCPyV) may be involved in causing cancer. The objective of this study was to assess the impact of MCPyV on the development of head and neck squamous cell carcinoma (HNSCC). In total, 50 paraffin-embedded HNSCC biopsy samples and 50 adjacent non-cancerous samples were evaluated for the presence of MCPyV DNA and RNA. Among patients, the five most frequent histopathologic sites were the tongue (22.0%), lip (16.0%), submandibular (14.0%), cheek (14.0%), and throat (14.0%). MCPyV DNA was positive in eight (16.0%) samples. The median MCPyV LT-Ag copy number in the eight positive samples and in one non-cancerous sample was 4.8 × 10-3 and 2.6 × 10-5 copies/cell, respectively. Quantification of MCPyV LT-Ag revealed increased expression in stage III (5.6 × 10-3 copies/cell) than in the other stages. The MCPyV DNA load in different stages of HNSCC was also statistically significant (P = 0.027). The viral load was low, suggesting that only a fraction of cancerous cells is infected. This result provides evidence confirming the presence of MCPyV in a subset of Iranian patients with HNSCCs, but further studies needed to confirm our findings.

Abstract
High-risk human papillomavirus (HR-HPV) is a causative agent for an increasing subset of oropharyngeal squamous cell carcinoma. HPV 16 accounts for 90% of cases. The chance for malignant transformation due to infection with high-risk HPV is proportional to the expression of the viral oncogene products E6 and E7, which inactivate p53 and retinoblastoma (Rb) tumor suppressor functions. P16 is a surrogate marker of HPV associated HNSCC and 2+/3+ expression in more than 75% cells is diagnostic. Molecular demonstration of integrated virus by in situ hybridization is specific but has low sensitivity. HPV associated oropharyngeal carcinomas classically arise in the tonsillar crypts and commonly have basaloid morphology with a prominent lymphocytic repsonse and minimal despmoplastic reaction. In situ vs invasive carcinomas may be difficult to distinguish in histology. The HPV postitivity overrides traditional prognostic indicators such as tumour grade and histological subtype. Small cell morphology carries a poorer prognosis as does marked tumour anaplasia and multinucleation. Lymph node metastasis is extensive and frequently cystic however extranodal extension, laterality or nodal sizes do not carry prognostic implications as in conventional OSCC and OPSCC. Stage IV is reserved for distant metastasis. HPV-16-positive patients had significantly reduced overall and disease-specific mortality rates and an improved 3-year overall survival (OS) and disease-free survival (DFS) compared to patients with HPV negative tumors. Surgical treatment is the main option for primary and secondary HNSCC. Targeted therapies including drugs targeting EGFR and PIK3CA and have shown some promising results. HPV pathway expressing tumors are less aggressive and may receive adequate curative intent therapy from a reduced radiation or chemotherapy dose revision. OSCC however fails to show a distinct difference between HPV associated and tobaccco associated cancer and prognostic differences do not clearly exist.

Abstract
Head neck squamous cell carcinomas (HNSCCs) are a significant cause of morbidity and mortality all around the world. Just like tobacco and alcohol, Human papilloma virus (HPV) infection is now recognized to play a role in the pathogenesis of a subset of HNSCCs. Unprotected sexual behaviours with the HPV carrier plays an important role in transmission of this virus. The global incidence of head and neck cancers is declining, but the incidence of HPV related head and neck cancers is rapidly increasing over the last few decades. However, most institutions do not mandate documentation of sexual history or counselling of patients regarding sexual practices like they do for tobacco and alcohol addictions in HNSCC patients. The aim of this review of literature is to analyse if there is a strong evidence to correlate oral sex with HPV related HNSCC and counsel the patient's regarding sexual behaviours.

Abstract
BACKGROUND The causal association between human papillomavirus (HPV) and oral squamous cell carcinoma (OSCC) remains controversial. Most of previous studies did not consider the potential modification effect of sexual behaviors when evaluating the role of HPV infection in OSCC risk. OBJECTIVES To explore the independent and joint effects of oral HPV infection and sexual behaviors on OSCC in Chinese population. STUDY DESIGN A case-control study was conducted from September 2012 to September 2015 in Fujian, China. HPV DNA genotypes were detected in tumor tissues of 178 OSCC patients and oral exfoliated cells of 189 frequency-matched controls using flow-through hybridization and gene chip. Epidemiologic data were collected with a structured questionnaire by face-to-face interviews. Odds ratios (ORs) and 95% confidence interval (CI) were estimated with unconditional logistic regression models. RESULTS The overall HPV prevalence was 14.04% in OSCC patients and 3.17% in controls. HPV-18 was the most prevalent type in cases and controls (10.67% vs. 2.12%). Oral HPV infection was strongly associated with an increased risk of OSCC: the ORs were 7.21 (95% CI: 2.61-19.88) for HPV16/18 and 7.59 (95% CI: 2.34-24.64) for HPV-18. Moreover, the significant associations were only observed in females, young adults, married population, merchants, non-smokers, non-alcohol drinkers and non-tea drinkers. Additionally, the first intercourse below 22years of age and oral sex practice did not show an association with OSCC. But there was a significantly multiplicative interaction between HPV 16/18 and age at first intercourse for OSCC (Pinteraction<0.001). CONCLUSIONS Oral HPV infection (specifically type 18) is an independent risk factor for OSCC in Fujian area. Furthermore, there might be a combined effect of HPV 16/18 and age at first intercourse on OSCC.

Abstract
This article reviews the significance of the microbiome in cancer epidemiology, mechanistic and technical challenges in the field, and characterization of the microbiome in different tumor types to identify biomarkers of risk, progression, and prognosis. Publications on the microbiome and cancer epidemiology were reviewed to analyze sample collection and processing, microbiome taxa characterization by 16S ribosomal RNA sequencing, and microbiome metabolite characterization (metabotyping) by nuclear magnetic resonance and mass spectrometry. The analysis identified methodology types, research design, sample types, and issues in integrating data from different platforms. Aerodigestive cancer epidemiology studies conducted by different groups demonstrated the significance of microbiome information in developing approaches to improve health. Challenges exist in sample preparation and processing (eg, standardization of methods for collection and analysis). These challenges relate to technology, data integration from "omics" studies, inherent bias in primer selection during 16S ribosomal RNA sequencing, the need for large consortia with well-characterized biospecimens, cause and effect issues, resilience of microbiota to exposure events (requires longitudinal studies), and expanding studies for fungal and viral diversity (most studies used bacterial 16S ribosomal RNA sequencing for microbiota characterization). Despite these challenges, microbiome and cancer epidemiology studies are significant and may facilitate cancer risk assessment, diagnosis, and prognosis. In the future, clinical trials likely will use microbiota modifications to improve the efficacy of existing treatments.

Abstract
OBJECTIVE Recent evidence suggests that human papillomavirus (HPV)-related head and neck squamous cell carcinoma (HNSCC) is a separate HNSCC subgroup with distinct epidemiology, histopathological characteristics, therapeutic response to chemotherapy and radiation, and clinical outcome. This study aimed to investigate the role of HPV infection in oral squamous cell carcinoma (OSCC) and the correlation between HPV infection, tumor suppressor protein p16 expression, and clinicopathological features in Japanese patients. METHODS In total, 174 OSCC specimens were examined for p16 levels by immunohistochemistry, and p16-positive OSCCs were analyzed for HPV DNA by in situ hybridization (ISH) and HPV genotypes by real-time PCR. The results were evaluated for the association with clinicopathological characteristics of OSCC patients. RESULTS Twenty-four OSCC samples were found positive for p16 expression; all of them were well-differentiated tumors. P16 immunoreactivity was significantly associated with the invasion depth and tended to correlate with sex, site in the oral cavity, stromal reaction, TNM stage, and survival. HPV DNA was detected in 13 of 24 (54%) p16-positive OSCC by real-time PCR; HPV 16, 18, and other high-risk genotypes were the most prevalent. However, ISH failed to detect HPV DNA in p16-positive OSCCs. CONCLUSION P16 immunoreactivity and HPV genotyping by real-time PCR may be useful markers of HPV infection in OSCC. However, although HPV-related OSCC showed good outcomes, HPV infection may have a minor role in oral oncogenesis in Japanese patients.

Abstract
Oral cancer is one of the commonest causes for mortality and morbidity with squamous cell carcinoma being the sixth most frequent malignant tumour worldwide. In addition to tobacco and alcohol, human papilloma virus (HPV) is associated with a proportion of head and neck cancers. As in cervical cancers, HPV types 16 and 18 are the cause of malignant transformation. HPV-positive cancers of head and neck have unique characteristics such as occurrence in a younger age group, distinct clinical and molecular features, and better prognosis as compared to HPV-negative carcinomas. They also possess the potential for prevention by using vaccination. The present review describes in detail the salient features of HPV associated oral squamous cell carcinoma (OSCC), its differences from HPV-negative OSCC, diagnostic features, and recent strategies in prevention and management.

Abstract
Background Oral and pharyngeal cancer (OPC) of multifactorial aetiology is a major health problem globally. Ranking first in all cancers, OPC poses a significant impact on the Sri Lankan male population. As Human Papillomavirus (HPV) high risk (HR) types are found to be significant risk factors for OPC globally, the current study was undertaken to examine the association between HR-HPV16 and 18 types with OPC in Sri Lanka. Materials and methods Serum samples of 78 OPC patients and 51 non-cancer controls were assayed for the presence of anti-HPV16 and anti-HPV18 IgG antibodies using in-house established Enzyme Linked Immunosorbent Assays (ELISAs). The association between OPC and its risk factors i.e. HPV, smoking, alcohol, betel quid, poor dentition, was established using Chi-square test. Logistic regression was used to calculate odds ratios (OR), adjusted for the influence of other risk factors. Results This prototype study in Sri Lanka showed a significant risk of 15 fold in developing OPC due to HPV16/18 seropositivity after removing variability due to other factors. Oncogenic HPV18 showed a higher rate of seropositivity being detected in 32% of OPC patients, and also in 2% of non-cancer control subjects. HR-HPV16 was detected in 23% of OPC patients and in 5.88% of controls. Moreover, seven OPC patients were detected with both anti-HPV16 and anti-HPV18 antibodies. According to the logistic regression models HPV18 seropositivity was associated with a 28 fold risk in developing OPC while that of HPV16 was associated with a 6 fold increase in risk for the development of OPC. A 5 fold risk of developing OPC was also pronounced among smokers while alcohol, betel and poor dentition was not significantly associated with OPC. Statistically significant differences with regard to age, gender, smoking, alcohol, betel use, poor dentition and site specificity of the tumour was not observed between HPV seropositive and seronegative OPC patients. Conclusions Both in-house developed ELISAs detected significant proportions of HPV seropositives within the OPC study population suggestive of HPV as a strong risk factor for oral and pharyngeal carcinogenesis in Sri Lanka.

Abstract
The importance of HPV in world healthy is high, in fact high-risk HPV types contribute significantly to viral associated neoplasms. In this article we will analyze vary expression of HPV in oral cavity both benign and malignant, their prevalence and the importance in early diagnosis and prevention. The classical oral lesions associated with human papillomavirus are squamous cell papilloma, condyloma acuminatum, verruca vulgaris and focal epithelial hyperplasia. Overall, HPV types 2, 4, 6, 11, 13 and 32 have been associated with benign oral lesions while HPV types 16 and 18 have been associated with malignant lesions, especially in cancers of the tonsils and elsewhere in the oropharynx. Transmission of the virus can occur with direct contact, genital contact, anal and oral sex; latest studies suggest a salivary transmission and from mother to child during delivery. The number of lifetime sexual partners is an important risk factor for the development of HPV-positive head-neck cancer. Oral/oropharyngeal cancer etiologically associated with HPV having an increased survival and a better prognostic (85%-90% to five years). There is no cure for the virus. There are two commercially available prophylactic vaccines against HPV today: the bivalent (16 and 18) Cervarix® and the tetravalent (6, 11, 16 and 18) Gardasil® and new vaccine Gardasil 9 (6, 11, 16, 18, 31, 33, 45, 52, 58) was approved in the United States. To be effective, such vaccination should start before "sexual puberty". The vaccine could be an important preventive strategy, in fact the scientific community is in agreement on hypothesis that blocking the contagion it may also limit the distance complications as the oropharyngeal cancer.

Med Oral Patol Oral Cir Bucal 2014; 19:e538-44. [PMID: 24880448 PMCID: PMC4259367 DOI: 10.4317/medoral.19748] [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: 12/17/2013] [Accepted: 02/17/2014] [Indexed: 11/15/2022] Open
Abstract
Objectives: To evaluate the effectiveness of Toki’s criteria in identifying the HPV L1 protein in oral lesions with the use of immunohistochemistry (IHC) and to determine which criteria optimize such identification.
Study Design: Retrospective study of 277 cases diagnosed as HPV lesions at 22 years. Tests of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), kappa coefficients, and chi2 values, as well as two logistic regression analyses (p≤0.05), were conducted.
Results: Of the lesions studied, 96.4% (267 of 277) were positive for HPV using Toki’s criteria and 28.5% (79 of 277) were positive for L1 by IHC. Toki’s criteria showed sensitivity=93.67%, specificity=2.53%, PPV=6.99%, and NPV=46.55%. Neither concordance nor statistically significant associations were observed between both tests. The logistic regression of Toki’s criteria was useful in the diagnosis of L1, correctly classified 71.8% of the lesions positive for L1, and showed a Hosmer-Lemeshow adjustment of p=0.614 and a Nagelkerke’s coefficient of determination of 6.8%. The explanatory variables statistically significant at p≤0.05 were dyskeratosis (p=0.01) and papillomatosis (p=0.04). Forty-nine independent variables (clinical and histopathologic) were involved in the second regression analysis. The model correctly classified 85.2% of the lesions and showed a Hosmer-Lemeshow adjustment of p=0.696 and a Nagelkerke’s coefficient of determination of 60.2%. The explanatory variables statistically significant atp≤0.05 were: age younger than 35 years (p=0.001), multiple lesions (p=0.031), hyperorthokeratosis (p=0.019), focal intracellular edema (p=0.002), and the presence of 1 to more than 5 cells with degenerative changes in their nucleus (p=0.048).
Conclusions: Toki’s criteria are not adequate to make a diagnosis of lesions by HPV in the mouth, but the logistic regression analysis showed clinical and histopathologic variables which optimize the identification of lesions through the L1 protein. However, a PCR study is advisable when the presence of high-risk HPV is suspected.
Key words:HPV, Toki’s criteria.

Abstract
Aims: The aim of this study is to evaluate the expression of human papilloma virus (HPV) in oral squamous cell carcinoma (OSCC) and to correlate the association of HPV in histological grades of OSCC using p16 (p16INK4a) immunohistochemistry (IHC). Subjects and Methods: This study consists of 30 histological diagnosed cases of OSCC (10-well-differentiated oral squamous cell carcinoma [WDOSCC], 10-moderately differentiated oral squamous cell carcinoma [MDOSCC] and 10-poorly differentiated oral squamous cell carcinoma [PDOSCC]). The sections were subjected to IHC procedure using p16. Two parameters in immunohistochemical p16 expression were evaluated by 3 observers based on the criteria by Galgano M. Tetal (2010) (a) percentage of p16 positive cases (b) pattern of p16 staining in various grades of OSCC. Statistical Analysis Used: Kappa test. Results: Totally, 30 samples of 0SCC, p16 positivity was noted in 26/30 (86.66%). Of 26 positive cases, p16 staining was positive in 7/10 (70%) of WDOSCC, 9/10 (90%) in MDOSCC and, 10/10 (100%) PDOSCC. Incidentally, we also found single dispersed cell staining in WDOSCC, patchy staining in MDOSCC and more diffuse staining pattern predominant in PDOSCC. Conclusions: Our study revealed an association between HPV and OSCC. Diffuse staining pattern was noted in PDOSCC, which in turn depicts the increase viral overload, which might have an influence on its aggressive behavior.

Abstract
Human papillomavirus (HPV) infection is a major cause of cervical cancer and its precancerous diseases. Cervical cancer is the second deadliest cancer killer among women worldwide. Moreover, HPV is also known to be a causative agent of oral, pharyngeal, anal and genital cancer. Recent application of HPV structural protein (L1)-targeted prophylactic vaccines (Gardasil® and Cervarix®) is expected to reduce the incidence of HPV infection and cervical cancer, and possibly other HPV-associated cancers. However, the benefit of the prophylactic vaccines for treating HPV-infected patients is unlikely, underscoring the importance of developing therapeutic vaccines against HPV infection. In this regard, numerous types of therapeutic vaccine approaches targeting the HPV regulatory proteins, E6 and E7, have been tested for their efficacy in animals and clinically. In this communication, we review HPV vaccine types, in particular DNA vaccines, their designs and delivery by electroporation and their immunologic and antitumor efficacy in animals and humans, along with the basics of HPV and its pathogenesis.
