Abstract
Human papilloma virus (HPV) infection is a major risk factor for a distinct subset of head and neck squamous cell carcinoma (HNSCC). The current review summarizes the epidemiology of HNSCC and the disease burden, the infectious cycle of HPV, the roles of viral oncoproteins, E6 and E7, and the downstream cellular events that lead to malignant transformation. Current techniques for the clinical diagnosis of HPV-associated HNSCC will also be discussed, that is, the detection of HPV DNA, RNA, and the HPV surrogate marker, p16 in tumor tissues, as well as HPV-specific antibodies in serum. Such methods do not allow for the early detection of HPV-associated HNSCC and most cases are at an advanced stage upon diagnosis. Novel noninvasive approaches using oral fluid, a clinically relevant biological fluid, allow for the detection of HPV and cellular alterations in infected cells, which may aid in the early detection and HPV-typing of HNSCC tumors. Noninvasive diagnostic methods will enable early detection and intervention, leading to a significant reduction in mortality and morbidity associated with HNSCC.

Abstract
Oral innate immunity, an important component in host defense and immune surveillance in the oral cavity, plays a crucial role in the regulation of oral health. As part of the innate immune system, epithelial cells lining oral mucosal surfaces not only provide a physical barrier but also produce different antimicrobial peptides, including human β-defensins (hBDs), secretory leukocyte protease inhibitor (SLPI), and various cytokines. These innate immune mediators help in maintaining oral homeostasis. When they are impaired either by local or systemic causes, various oral infections and malignancies may be developed. Human immunodeficiency virus (HIV) infection and other co-infections appear to have both direct and indirect effects on systemic and local innate immunity leading to the development of oral opportunistic infections and malignancies. Highly active antiretroviral therapy (HAART), the standard treatment of HIV infection, contributed to a global reduction of HIV-associated oral lesions. However, prolonged use of HAART may lead to adverse effects on the oral innate immunity resulting in the relapse of oral lesions. This review article focused on the roles of oral innate immunity in HIV infection in HAART era. The following five key questions were addressed: (i) What are the roles of oral innate immunity in health and disease?, (ii) What are the effects of HIV infection on oral innate immunity?, (iii) What are the roles of oral innate immunity against other co-infections?, (iv) What are the effects of HAART on oral innate immunity?, and (v) Is oral innate immunity enhanced by HAART?

Abstract
Human papillomavirus (HPV) has been shown to have a causal role in the development of head and neck squamous cell carcinoma. While HPV-positive head and neck cancer is associated with a better response to treatment in the majority of patients, there is a subset who does not respond favorably to current therapy. Identification of these patients could prevent unnecessary morbidity and indicate the need for alternative therapeutic options. Tissue samples were obtained from 19 patients with HPV-positive head and neck squamous carcinoma treated with chemoradiation therapy. HPV status was confirmed by polymerase chain reaction analysis through detection of HPV16 E7 in both DNA and RNA. RNA was isolated from tissue samples and subjected to microarray gene expression analysis. In addition to identification of potential genetic biomarkers (including LCE3D, KRTDAP, HMOX1, KRT19, MDK, TSPAN1), differentially expressed genes associated with genomic stability, cell cycle, and DNA damage were detected between responders and non-responders. These results were further validated with publicly available gene expression studies. This pilot study suggests prospective biomarkers that predict response to therapy. The importance of genes involved with genomic stability is highlighted in both development and progression of head and neck squamous cell carcinoma but also recurrence. Potential development of an assay may prove beneficial to clinicians, assisting them to provide alternative care sooner thus lowering morbidity.

Abstract
IMPORTANCE Human papillomavirus type 16 (HPV-16) is a major causative factor in oropharyngeal squamous cell carcinoma (OPSCC). The detection of primary OPSCC is often delayed owing to the challenging anatomy of the oropharynx. OBJECTIVE To investigate the feasibility of HPV-16 DNA detection in pretreatment and posttreatment plasma and saliva and its potential role as a marker of prognosis. DESIGN, SETTING, AND PARTICIPANTS This is a retrospective analysis of a prospectively collected cohort. Among a cohort of patients with oropharyngeal and unknown primary squamous cell carcinoma with known HPV-16 tumor status from the Johns Hopkins Medical Institutions and Greater Baltimore Medical Center (from 1999 through 2010), 93 patients were identified with a complete set of pretreatment and posttreatment plasma or saliva samples, of which 81 patients had HPV-16-positive tumors and 12 patients had HPV-16-negative tumors. Real-time quantitative polymerase chain reaction was used to detect HPV-16 E6 and E7 DNA in saliva and plasma samples. MAIN OUTCOMES AND MEASURES Main outcomes included sensitivity, specificity, negative predictive value of combined saliva and plasma pretreatment HPV-16 DNA status for detecting tumor HPV-16 status, as well as the association of posttreatment HPV DNA status with clinical outcomes, including recurrence-free survival and overall survival. RESULTS The median follow-up time was 49 months (range, 0.9-181.0 months). The sensitivity, specificity, negative predictive value, and positive predictive value of combined saliva and plasma pretreatment HPV-16 DNA status for detecting tumor HPV-16 status were 76%, 100%, 42%, and 100%, respectively. The sensitivities of pretreatment saliva or plasma alone were 52.8% and 67.3%, respectively. In a multivariable analysis, positive posttreatment saliva HPV status was associated with higher risk of recurrence (hazard ratio [HR], 10.7; 95% CI, 2.36-48.50) (P = .002). Overall survival was reduced among those with posttreatment HPV-positive status in saliva (HR, 25.9; 95% CI, 3.23-208.00) (P = .002) and those with HPV-positive status in either saliva or plasma but not among patients with HPV-positive status in plasma alone. The combined saliva and plasma posttreatment HPV-16 DNA status was 90.7% specific and 69.5% sensitive in predicting recurrence within 3 years. CONCLUSIONS AND RELEVANCE Using a combination of pretreatment plasma and saliva can increase the sensitivity of pretreatment HPV-16 status as a tool for screening patients with HPV-16-positive OPSCC. In addition, analysis of HPV-16 DNA in saliva and plasma after primary treatment may allow for early detection of recurrence in patients with HPV-16-positive OPSCC.

Abstract
The purpose of this study was to evaluate the survival of patients with SCC of the oropharynx, according to the presence of HPV and tobacco consumption. A total of 37 patients were followed up for at least 5 years after being diagnosed with SCC of the oropharynx. The biopsy tissue was submitted to the polymerase chain reaction (PCR) and in situ hybridization (ISH) methods for broad determination of HPV presence, to identify the presence of high-risk viruses (16 and 18). 12 of the 37 (32.4%) samples were HPV positive, whereas the two specific types of virus were identified in two samples for HPV-16 and in no samples for HPV-18. We observed no significant effect of the virus in survival analysis, irrespective of tobacco consumption. The level of tobacco consumption was significantly higher in the group of HPV-negative patients (P = 0.0283), in which all the patients in this group were smokers. Therefore, HPV did not change the survival of patients with SCC of the oropharynx in this study, indicating that factors other than tobacco need to be studied in conjunction with it, and the level of tobacco consumption is significantly higher in the group of HPV-negative patients.

Abstract
Head and neck squamous cell carcinoma (HNSCC) comprise a wide spectrum of neoplasms with different tumor biologies, prognosis and response to therapies. Current tumor classification and traditional diagnostic methods (e.g. clinical assessment, histopathology) are limited in their capacity to determine prognosis and clinical decision-making. Despite recent improvements in treatment, the outcome for patients with HNSCC remains poor. Similar to most tumors, several patient-related factors, (e.g. genetics and environment) and disease-related factors (e.g. tumor location, TMN staging) play a significant role on survival. Thus, the problem in defining the prognosis is that the clinical course and response to treatment differ considerably among patients. Such interindividual variability is related to the heterogeneity of the tumor, genetic and epigenetic variations, thus reflecting the interaction of multiple biological components that result in a unique phenotype. Integrative genomics are developed to identify the molecular pathways leading to cancer at the individual level and find novel prognostic markers for HNSCC, hence tailoring a treatment accordingly. Such genetic-based personalized diagnosis allows tumor stratification and implementation of targeted therapy. Modern medicine includes new drugs that disrupt the implicated molecules and their signaling pathways. Here, we summarize the current state of knowledge that elucidates the translation of genetic data into clinical benefit.

Abstract
INTRODUCTION Human papillomavirus (HPV) is the most clinically common sexually transmitted infection due to its carcinogenic power and the high number of lesions that it causes at different sites of the human body. MATERIAL AND METHODS Genital tract organs are the most common sites where the virus can be found, but by increasing the sensitivity of diagnostic technique, it is possible to identify viral presence in different regions of the body such as the stomach, the lung, and the urinary tract. These findings break with the traditional HPV skin/genital tropic profile and demonstrate that the virus is capable of infecting a wide variety of cells, tissues, and organs or can, at least, survive in these areas. The widespread presence of the HPV in the human body, often in latent form, led us to consider the hypothesis that HPV latency may be associated with no disease. CONCLUSION This observation raises further questions about the possibility of the virus not causing disease in specific sites of the human body, but rather, behaving like a commensal/opportunistic microorganism.

Abstract
Much recent attention has highlighted a subset of head and neck squamous cell carcinomas (HNSCCs) related to human papillomavirus (HPV) that has an epidemiologic, demographic, molecular and clinical profile which is distinct from non-HPV-related HNSCC. The clinical significance of detecting HPV in a HNSCC has resulted in a growing expectation for HPV testing of HNSCCs. Although the growing demand for routine testing is understandable and appropriate, it has impelled an undisciplined approach that has been largely unsystematic. The current state of the art has now arrived at a point where a better understanding of HPV-related tumorigenesis and a growing experience with HPV testing can now move wide scale, indiscriminant and non-standardized testing towards a more directed, clinically relevant and standardized approach. This review will address the current state of HPV detection; and will focus on why HPV testing is important, when HPV testing is appropriate, and how to test for the presence of HPV in various clinical samples. As no single test has been universally accepted as a best method, this review will consider the strengths and weaknesses of some of the more commonly used assays, and will emphasize some emerging techniques that may improve the efficiency of HPV testing of clinical samples including cytologic specimens.

Abstract
OBJECTIVES To evaluate the role of HPV in oral carcinogenesis, we examined the prevalence of HPV in malignant, potentially malignant and normal oral epithelium and studied the relation of HPV prevalence with other factors obtained from the patient's records. MATERIALS AND METHODS Our material consisted of 291 tissue specimens from 258 individuals. From every individual formalin fixed and paraffin embedded tissues were examined by nested Polymerase Chain Reaction (NPCR) for the detection of HPV DNA and by immunohistochemistry (IHC) for the in situ detection of HPV L1 protein. Positive PCR products were sequenced in order to type HPVs. Also 33 fresh tissues were obtained, fixed and used to detect HPV particles by transitional electron microscopy (TEM). RESULTS HPV was detected in 32.9% of the tissue specimens by NPCR, in 4.7% by immunohistochemistry and in 28.1% by TEM. In detail, by nested PCR HPV L1 DNA was detected in 40% of normal tissues, 40% of fibromas, 35.8% of non-dysplastic leukoplakias, 31.6% of dysplastic leukoplakias and 22.2% of oral squamous cell carcinomas. The HPV viral load of 96.5% of the samples was very low (1 viral copy per 10(2)-10(4) cells). HPV16 prevails in all histological groups in 89-100%. CONCLUSION We conclude that HPV does not seem, from the specific sample examined, to play a substantial role in oral carcinogenesis. However, it cannot be excluded that HPV could be involved in oral carcinogenesis only in cases with high viral load or at early stages of carcinogenesis possibly through the hit-and-run mechanism.

Abstract
OBJECTIVE To investigate the presence and persistence of human papillomavirus (HPV) infection in the oral mucosa of patients with head and neck squamous cell carcinoma (HNSCC), and its correlation with prognosis. STUDY DESIGN HPV infection was characterized in tumors and pre and posttreatment oral scrapings in 51 patients with HNSCC and matched controls using the SPF10 LiPA Extra assay. p16INK4A immunostain and in situ hybridization for high-risk HPV genotypes recognized transcriptionally active infection in tumor samples. The risk of infection was compared in patients and controls. The association of pretreatment HPV status with recurrence and survival and with posttreatment HPV persistence was assessed. RESULTS Oral HPV infection risk was significantly higher in patients with HNSCC than in controls (P < .001). Oral HPV infection was associated with infection in the first posttreatment scrapings (P = .015), but did not affect recurrence or prognosis. CONCLUSION Oral HPV infection is frequent in patients with HNSCC and has no prognostic implications, suggesting that posttreatment polymerase chain reaction monitoring on oral cells is not effective to monitor patient recurrence risk.

Abstract
BACKGROUND Determining high-risk human papillomavirus (HR-HPV) status of head and neck squamous cell carcinoma (HNSCC) defines a tumor subset with important clinical implications. Cytologic sampling often provides the sentinel or sole diagnostic specimen. The authors assessed the performance characteristics for the Roche cobas 4800 HPV real-time polymerase chain reaction (PCR)-based system (cobas) on cytologic specimens of HNSCC compared with standard methods of in situ hybridization (ISH) for HR-HPV and immunohistochemistry (IHC) for p16 on formalin-fixed, paraffin-embedded (FFPE) tissue. METHODS Samples of HNSCC were collected by fine-needle aspiration and from surgical biopsies or resections, fixed, and processed with the cobas system. Available corresponding FFPE samples were synchronously evaluated for HR-HPV using ISH and IHC. Discrepant cases underwent additional PCR studies for adjudication. RESULTS Thirty-six samples from 33 patients were analyzed. Forty-two percent (n = 15) of tumors were positive for HR-HPV according to cobas. Corresponding histology with ISH (n = 30) was concordant in 91% of samples. Compared with the adjudication PCR standard, there were 3 false-positive cases according to cobas. Ninety-two percent (n = 12) of cases were the HPV16 subtype. The overall sensitivity for the cobas system was 100%, and the specificity was 86%. CONCLUSIONS Concordance in HNSCC HR-HPV status between cobas and ISH/IHC was > 90%, and cobas demonstrated a sensitivity of 100% and a specificity of 86%, broadening options for HR-HPV testing of fine-needle aspiration samples. Advantages for this system include subtyping of HR-HPV and the ability to discern HR-HPV status earlier in a patient's treatment course.

Human papilloma virus (HPV) has been detected in some upper aerodigestive tract tumors, but the correlation between HPV and these tumors is not well understood. There is also some controversy regarding this correlation because a large variation in the prevalence of HPV in these tumors has been reported. To discuss the impact of HPV infection on upper aerodigestive tract tumors, this review estimated systematically the prevalence and risk of HPV in upper aerodigestive tract tumors from studies published between 1982 and 2012. In total, 418 articles were selected, which included 273 studies on the head and neck and 145 studies on esophageal squamous cell carcinoma. The overall prevalence of HPV in the 5,467 head and neck squamous cell carcinoma specimens was 36.3%. HPV was detected more frequently in the Americas (40%), than in Asia (38.6%), Europe (32%), or others regions (30.5%). The prevalence of HPV was significantly higher in oropharyngeal (48.5%) than in oral (32.5%), laryngeal (30.7%), and unselected head and neck squamous cell carcinoma (33.3%) (P < 0.001). The pooled prevalence of HPV in the 6,912 esophageal squamous cell carcinoma cases was 38.9% and it was significantly higher in China (44%) versus other regions (31.3%) (P < 0.05). Meta-analysis showed that head and neck and esophageal squamous cell carcinoma are associated with HPV infection (combined OR: 3.58, OR for head and neck and esophageal squamous cell carcinoma: 4.20). These findings suggest that HPV might be linked etiologically to the development of some upper aerodigestive tract tumors.

Abstract
BACKGROUND Diagnostics that involve the use of oral fluids have become increasingly available commercially in recent years and are of particular interest because of their relative ease of use, low cost and noninvasive collection of oral fluid for testing. TYPES OF STUDIES REVIEWED The authors discuss the use of salivary diagnostics for virus detection with an emphasis on rapid detection of infection by using point-of-care devices. In particular, they review salivary diagnostics for human immunodeficiency virus, hepatitis C virus and human papillomavirus. Oral mucosal transudate contains secretory immunoglobulin (Ig) A, as well as IgM and IgG, which makes it a good source for immunodiagnostic-based devices. CLINICAL IMPLICATIONS Because patients often visit a dentist more regularly than they do a physician, there is increased discussion in the dental community regarding the need for practitioners to be aware of salivary diagnostics and to be willing and able to administer these tests to their patients.

Abstract
Human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) is an entity with peculiar clinical and molecular characteristics, which mainly arises from the reticulated epithelium lining the crypts of the palatine tonsils and the base of the tongue. The only head and neck site with a definite etiological association between persistent high-risk (HR) HPV infection and development of SCC is the oropharynx. HPV-positive malignancies represent 5-20% of all HNSCCs and 40-90% of those arising from the oropharynx, with widely variable rates depending on the geographic area, population, relative prevalence of environment-related SCC and detection assay. HPV-16 is by far the most common HR HPV genotype detected in oropharyngeal SCC (OPSCC), and the only definitely carcinogenic genotype for the head and neck region. Patients with HPV-induced OPSCC are more likely to be middle-aged white men, non-smokers, non-drinkers or mild to moderate drinkers, with higher socioeconomic status and better performance status than subjects with HPV-unrelated SCC. HPV-induced HNSCCs are often described as non-keratinizing, poorly differentiated or basaloid carcinomas, and are diagnosed in earlier T-category with a trend for a more advanced N-category, with cystic degeneration, than the HPV-unrelated carcinomas. HPV positivity is associated with better response to treatment and modality-independent survival benefit. Treatment selection in HPV-related oropharyngeal carcinoma is becoming a critical issue, and although there is no evidence from randomized, controlled trials to support a treatment de-escalation in HPV-positive SCC, some investigators argue that intensive combined modality strategies may represent an overtreatment.

Abstract
The role of human papilloma viruses (HPV) in malignant and nonmalignant ENT diseases and the corresponding epidemiological burden has been widely described. International head and neck oncology community discussed growing evidence that oral HPV infection contributes to the risk of oro-pharyngeal carcinoma (OPC) and recommended HPV testing as a part of the work up for patients with OPC. Polish Society of ENT Head Neck Surgery and National Chamber of Laboratory Diagnosticians have worked together to define the minimum requirements for assigning a diagnosis of HPV-related conditions and testing strategy that include HPV specific tests in our country. This paper briefly frames the literature information concerning low risk (LR) and high risk (HR) HPV, reviews the epidemiology, general guidance on the most appropriate biomarkers for clinical assessment of HPV. The definition of HPV-related cancer was presented. The article is aiming to highlight some of major issues for the clinician dealing with patients with HPV-related morbidities and to introduce the diagnostic algorithm in Poland.

Abstract
INTRODUCTION As the traditional risk factors for oral squamous cell carcinoma, especially tobacco, decline, new potential causative agents become the focus of research. Since the discovery of human papillomavirus (HPV) and its importance in carcinogenesis in cervical cancer, a lot of research has been undertaken to define its role in different types of cancer. In the present study, we evaluate the role of high-risk HPV types in initiation and progression of oral squamous cell carcinoma (OSCC) using a systematic review of the current literature. MATERIAL AND METHODS A literature research with the search term "HPV oral squamous cell carcinoma" was performed via PubMed. Results were screened systematically for relevance and classified into the following categories: molecular biology, genetics, clinical aspects, and prevalence. Articles were then further analyzed to assess quality. RESULTS The literature research led to 527 results, with an overall HPV prevalence of 30.1 % in OSCCs. The most frequently identified subtypes were HPV-16 and HPV-18 (25.4 and 18.1 %, respectively). Prognostic relevance of HPV was discussed controversially. HPV detection via polymerase chain reaction is the most established method today. Molecular changes according to carcinogenic pathways described for cervix carcinoma were not routinely found in OSCC. In general, no definite role of high-risk HPV is currently deducible from the literature. CONCLUSIONS High-risk subtypes 16 and 18 are present in the genome in approximately one third of OSCC. Its role as a causative agent is less clear than the role in oropharyngeal tumors. The infection might not be the cause of carcinogenesis in a significant number of patients but may become proportionally more important with the decrease of the classical risk factors of tobacco and alcohol.

Abstract
Evidence for transcriptional activation of the viral oncoproteins E6 and E7 is regarded as the gold standard for the presence of clinically relevant human papillomavirus (HPV), but detection of E6/E7 mRNA requires RNA extraction and polymerase chain reaction amplification-a challenging technique that is restricted to the research laboratory. The development of RNA in situ hybridization (ISH) probes complementary to E6/E7 mRNA permits direct visualization of viral transcripts in routinely processed tissues and has opened the door for accurate HPV detection in the clinical care setting. Tissue microarrays containing 282 head and neck squamous cell carcinomas from various anatomic subsites were tested for the presence of HPV using p16 immunohistochemistry, HPV DNA ISH, and an RNA ISH assay (RNAscope) targeting high-risk HPV E6/E7 mRNA transcripts. The E6/E7 mRNA assay was also used to test an additional 25 oropharyngeal carcinomas in which the HPV status as recorded in the surgical pathology reports was equivocal due to conflicting detection results (ie, p16 positive, DNA ISH negative). By the E6/E7 mRNA method, HPV was detected in 49 of 282 (17%) HNSCCs including 43 of 77 (56%) carcinomas from the oropharynx, 2 of 3 (67%) metastatic HNSCCs of an unknown primary site, 2 of 7 (29%) carcinomas from the sinonasal tract, and 2 of 195 (1%) carcinomas from other head and neck sites. p16 expression was strongly associated with the presence of HPV E6/E7 mRNA: 46 of 49 HPV-positive tumors exhibited p16 expression, whereas only 22 of 233 HPV-negative tumors were p16 positive (94% vs. 9%, P<0.0001). There was also a high rate of concordance (99%) between the E6/E7 mRNA method and HPV DNA ISH. For the selected group of discordant HNSCCs (p16/HPV DNA), the presence of E6/E7 transcripts was detected in 21 of 25 (84%) cases. The E6/E7 mRNA method confirmed the presence of transcriptionally active HPV-related HNSCC that has a strong predilection for the oropharynx and is strongly associated with high levels of p16 expression. Testing for HPV E6/E7 transcripts by RNA ISH is ideal because it confirms the presence of integrated and transcriptionally active virus, permits visualization of viral transcripts in tissues, and is technically feasible for routine testing in the clinical laboratory.

Abstract
Background Human papillomaviruses (HPV) are oncogenic and mainly associated with cervical cancers. Recent evidence has demonstrated HPV infection in other tissues, including oral epithelia and mucosa. Although a recent pilot study provided new information about oral HPV status in healthy adults from Nevada, no information was obtained about oral HPV prevalence among children or teenagers, therefore, the goal of this study is to provide more detailed information about oral prevalence of high-risk HPV among children and teenagers in Nevada. Methods This retrospective study utilized previously collected saliva samples, obtained from pediatric dental clinic patients (aged 2 – 11) and local school district teenagers (aged 12-17) for high-risk HPV screening (n=118) using qPCR for quantification and confirmation of analytical sensitivity and specificity. Results A small subset of saliva samples were found to harbor high-risk HPV16 (n=2) and HPV18 (n=1), representing a 2.5% of the total. All three were obtained from teenage males, and two of these three samples were from White participants. Conclusions Although this retrospective study could not provide correlations with behavioral or socioeconomic data, this project successfully screened more than one hundred saliva samples for high-risk HPV, confirming both HPV16 and HPV18 strains were present in a small subset. With increasing evidence of oral HPV infection in children, this study provides critical information of significant value to other dental, medical, oral and public health professionals who seek to further an understanding of oral health and disease risk in pediatric populations.

Exfoliated cells of the oral mucosa for HPV typing by SPF10 in head and neck cancer. J Virol Methods 2012; 186:99-103.

Abstract
HPV infection in the superficial cells of the oral mucosa could reflect the presence of HPV in head and neck cancer cells. Due mostly to the use of heterogeneous analytical methods, discordant data exist in the literature regarding the agreement between the presence of HPV in non-neoplastic oral mucosa and in tumour tissue from the same patient. The presence of HPV DNA and viral types were compared in paired cytological and biopsy samples from 56 patients with head and neck neoplastic and preneoplastic lesions using the highly sensitive SPF10 LiPA Extra assay, which has been validated recently for formalin-fixed paraffin-embedded tissue using paired cervical cytology and biopsy samples. Kappa statistics were used to measure the inter-rater agreement. The overall agreement with respect to HPV infection was 96.43% (kappa=0.8367). For 76.79% of subjects (kappa=0.6937), the same number of HPV types was detected in cytological and biopsy specimens. The overall positive typing agreement was 90.90%, comprising 130 out of 143 individual HPV type analyses. The agreement shown was good for HPV 18, 44, 45, 54 and 66 (kappa=0.6585-0. 7321), excellent for HPV 6, 16, 40, and 54 (kappa=0.8108-0.8679), and absolute for HPV 11, 31, 33, 35, 39, 51, 52, 53, 59, 74, and 69-71 (kappa=1.0000). The high sensitivity of the SPF10 LiPA and its excellent performance both for recognising HPV infection and for identifying the viral types present in tumour tissue and in oral exfoliated cells make it a useful method for the assessment of HPV infection in patients with head and neck cancer. The excellent agreement for HPV infection and genotyping in paired samples suggests that oral exfoliated cells can be used for HPV detection in the head and neck region.

Abstract
BACKGROUND Recently, the management of head and neck squamous cell carcinoma (HNSCC) has focused considerable attention on biomarkers, which may influence outcomes. Tests for human papilloma infection, including direct assessment of the virus as well as an associated tumour suppressor gene p16, are considered reproducible. Tumours from familial melanoma syndromes have suggested that nuclear localisation of p16 might have a further role in risk stratification. We hypothesised p16 staining that considered nuclear localisation might be informative for predicting outcomes in a broader set of HNSCC tumours not limited to the oropharynx, human papilloma virus (HPV) status or by smoking status. METHODS Patients treated for HNSCC from 2002 to 2006 at UNC (University of North Carolina at Chapel Hill) hospitals that had banked tissue available were eligible for this study. Tissue microarrays (TMA) were generated in triplicate. Immunohistochemical (IHC) staining for p16 was performed and scored separately for nuclear and cytoplasmic staining. Human papilloma virus staining was also carried out using monoclonal antibody E6H4. p16 expression, HPV status and other clinical features were correlated with progression-free (PFS) and overall survival (OS). RESULTS A total of 135 patients had sufficient sample for this analysis. Median age at diagnosis was 57 years (range 20-82), with 68.9% males, 8.9% never smokers and 32.6% never drinkers. Three-year OS rate and PFS rate was 63.0% and 54.1%, respectively. Based on the p16 staining score, patients were divided into three groups: high nuclear, high cytoplasmic staining group (HN), low nuclear, low cytoplasmic staining group (LS) and high cytoplasmic, low nuclear staining group (HC). The HN and the LS groups had significantly better OS than the HC group with hazard ratios of 0.10 and 0.37, respectively, after controlling for other factors, including HPV status. These two groups also had significantly better PFS than the HC staining group. This finding was consistent for sites outside the oropharynx and did not require adjustment for smoking status. CONCLUSION Different p16 protein localisation suggested different survival outcomes in a manner that does not require limiting the biomarker to the oropharynx and does not require assessment of smoking status.

Abstract
The confirmation of human papillomavirus (HPV) as a causative agent for a subset of squamous cell carcinomas of the head and neck has resulted in a growing expectation for HPV testing in head and neck cancers. An increasing understanding of HPV-related tumorigenesis has informed this evaluation process in a manner that is moving wide scale, indiscriminant, and nonstandardized testing toward a more directed, clinically relevant, and standardized approach. This review addresses the current state of HPV detection and focuses on the importance, appropriate time, and need for HPV testing.

Abstract
The infection of the head and neck epithelium by high-risk human papillomaviruses (HPV) is a risk factor for cancer onset and development. The incidence of HPV-related head and neck squamous cell carcinoma is currently increasing. These lesions display distinct clinical features. HPV positive patients are often younger and have a smaller history of tobacco smoking and alcohol drinking, but have a history of virus-transmitting sex practices. HPV-related tumours are mainly found in the oropharynx, are more associated to a local lymph node invasion and display a poorly differentiated morphology. Despite these more aggressive features, HPV-positive head and neck squamous cell carcinomas correlate with an improved local control, disease-free and global survival. It is thought that HPV-driven specific biologic abnormalities underlie higher tumour sensitivity to chemotherapeutic drugs and ionizing radiations. The expression of the HPV E6 and E7 oncoproteins induce cell transformation by interfering with cell signalling pathways involved in apoptosis, cell cycle, angiogenesis and induce the overexpression of the CDKN2A gene. Therefore, alternative treatments based on therapies targeting these pathways in combination with radiation dose de-escalation could be proposed to HPV-positive patients, if they are properly and reliably identified.

Abstract
Head and neck oncologists have traditionally relied on clinical tumor features and patient characteristics to guide care of individual patients. As surgical, radiotherapeutic, and systemic treatments have evolved to become more anatomically precise and mechanistically specific, the opportunity for improved cure and functional patient recovery has never been more promising for this historically debilitating cancer. However, personalized treatment must be accompanied by sophisticated patient selection to triage the application of advanced therapies toward ideal patient candidates. In this monograph, we review current progress, investigative themes, and key challenges facing head and neck cancer biomarker development intended to make personalized head and neck cancer treatment a clinical reality.

Abstract
BACKGROUND The objectives of this study were to determine (i) the prevalence and the copy numbers of oral human papilloma virus type 16 (HPV-16) in HIV-infected patients compared with non-HIV controls, and (ii) the effects of antiretroviral therapy (ART) and its duration on the virus. METHODS A cross-sectional study was carried out in HIV-infected patients with and without ART and in non-HIV controls. Saliva samples were collected, and the DNA extracted from those samples was used as a template to detect HPV-16 E6 and E7 by quantitative polymerase chain reaction. Student's t-test and ANOVA test were performed to determine the prevalence rates among groups. RESULTS Forty-nine HIV-infected patients: 37 on ART (age range, 23-54 years; mean, 37 years), 12 not on ART (age range, 20-40 years; mean, 31 years), and 20 non-HIV controls (age range, 19-53 years; mean, 31 years) were enrolled. The prevalence of oral HPV-16 infection and the copy numbers of the virus were significantly higher in HIV-infected patients than in non-HIV controls when using E6 assay (geometric mean = 10696 vs. 563 copies/10(5) cells, P < 0.001), but not E7 assay. No significant difference was observed between those who were and were not on ART. Long-term use of ART did not significantly change the prevalence of oral HPV-16 infection and the copy numbers of the virus (P = 0.567). CONCLUSION We conclude that the prevalence of oral HPV-16 infection and the copy numbers of the virus are increased by HIV infection. Neither the use of ART nor its duration significantly affected the virus.

High-risk human papillomavirus (HPV) screening and detection in healthy patient saliva samples: a pilot study. BMC Oral Health 2011; 11:28.

Abstract
Background The human papillomaviruses (HPV) are a large family of non-enveloped DNA viruses, mainly associated with cervical cancers. Recent epidemiologic evidence has suggested that HPV may be an independent risk factor for oropharyngeal cancers. Evidence now suggests HPV may modulate the malignancy process in some tobacco- and alcohol-induced oropharynx tumors, but might also be the primary oncogenic factor for inducing carcinogenesis among some non-smokers. More evidence, however, is needed regarding oral HPV prevalence among healthy adults to estimate risk. The goal of this study was to perform an HPV screening of normal healthy adults to assess oral HPV prevalence. Methods Healthy adult patients at a US dental school were selected to participate in this pilot study. DNA was isolated from saliva samples and screened for high-risk HPV strains HPV16 and HPV18 and further processed using qPCR for quantification and to confirm analytical sensitivity and specificity. Results Chi-square analysis revealed the patient sample was representative of the general clinic population with respect to gender, race and age (p < 0.05). Four patient samples were found to harbor HPV16 DNA, representing 2.6% of the total (n = 151). Three of the four HPV16-positive samples were from patients under 65 years of age and all four were female and Hispanic (non-White). No samples tested positive for HPV18. Conclusions The successful recruitment and screening of healthy adult patients revealed HPV16, but not HPV18, was present in a small subset. These results provide new information about oral HPV status, which may help to contextualize results from other studies that demonstrate oral cancer rates have risen in the US among both females and minorities and in some geographic areas that are not solely explained by rates of tobacco and alcohol use. The results of this study may be of significant value to further our understanding of oral health and disease risk, as well as to help design future studies exploring the role of other factors that influence oral HPV exposure, as well as the short- and long-term consequences of oral HPV infection.

Abstract
The aim of this study was to investigate a possible relation between oral squamous cell carcinoma (SCC), the presence of high-risk human papillomavirus (HR-HPV) DNA and p16 expression in young patients. Paraffin-embedded tumor blocks from 47 oral SCC of young (≤40-year old) patients were evaluated. The presence of HPV DNA in tumor specimens was analyzed by polymerase chain reaction (PCR) using GP5+/GP6+ generic primers (L1 region) followed by dot blot hybridization for HPV typing. When necessary, the HPV16 positivity was confirmed by PCR HPV16 E7-specific primers. Cases involving young patients were compared with 67 oral SCC from patients ≥50-year old (controls). Demographic and clinical data were collected to analyze patient outcomes. p16(ink4) expression was evaluated by immunostaining of tissue microarrays. HPV16 was detected in 22 (19.2%) cases; 15 (68.2%) young and 7 (31.8%) control patients, a statistically significant difference (p = 0.01). In 1 (1.7%) young group specimen, HPV DNA 16 and 18 was detected. p16 expression was observed in 11 (25.6%) cases from the young group and in 11 (19.6%) controls (p = 0.48). Association between HPV and p16 was verified, and it was statistically significant (p = 0.002). The higher prevalence of high-risk HPV types, especially HPV16, may be a contributing factor to oral carcinogenesis in younger individuals.

Abstract
BACKGROUND A growing proportion of head and neck squamous cell carcinoma (HNSCC) is caused by the human papillomavirus (HPV). In light of the unique natural history and prognosis of HPV-related HNSCCs, routine HPV testing is being incorporated into diagnostic protocols. Accordingly, there is an escalating demand for an optimal detection strategy that is sensitive and specific, transferrable to the diagnostic laboratory, standardized across laboratories, cost-effective, and amenable to broad application across specimen types including cytologic preparations. METHODS Cytologic preparations (fine-needle aspirates [FNAs] and brushes) were obtained from surgically resected HNSCCs and evaluated for the presence of high-risk HPV using the Hybrid Capture 2 assay. HPV analysis was also performed on the corresponding tissue sections using HPV in situ hybridization and p16 immunohistochemistry. In cases in which the immunohistochemical and in situ hybridization results were discordant, HPV status was determined by real-time polymerase chain reaction detection of E7 expression. HPV status in the tissues and corresponding cytologic samples was compared. RESULTS Based on benchmark HPV testing of the tissue sections, 14 HNSCCs were classified as HPV positive and 10 as HPV negative. All corresponding cytologic preparations were correctly classified using the Hybrid Capture 2 assay. CONCLUSIONS The Hybrid Capture 2 strategy, already widely used for the detection of high-risk HPV in cervical brushes, is readily transferrable to HNSCCs. Consistent accuracy in cytologic preparation suggests its potential application in FNAs from patients who present with lymph node metastases, and may eliminate the need to obtain tissue solely for the purpose of HPV testing.

Abstract
Cancer statistics report an increased incidence of OSCC and OPSCC around the world. Though improvements in screening and early diagnosis have dramatically reduced the incidence of this neoplasm in recent years, the 5-year-disease-free survival, is still poor, specially for oropharyngeal cancer, despite the great scientific and financial efforts. Recently, several papers showed that HPV may be involved at least in the pathogenesis of a subgroup of oral and cervical SCC, leading to distinct molecular characteristics compared with HPV-negative ones. Nevertheless, OPSCCs associated with HPV infection seem to show a better prognosis and affect younger patients (< 40 yrs.), especially females. Therefore, there is the need to properly assess oropharyngeal SCC subgroups: 1) not HPV associated/classic oral SCC: less responsive to anticancer drugs: needs novel post-surgical treatment; 2) HPV associated/oral SCC: needs several management options and suitable "target" therapy against the virus, and/or immune-stimulating therapy. Further issues are: 1) the disclosure of putative targets for more efficient molecular therapy, which may work as cervical cancer post-surgical treatment, in anticipation of the effects of "global prevention" performed by WHO anti-HPV vaccination programs; 2) careful identification of precancerous lesions in both sites; dysplasia is currently treated by excisional or ablative procedures, which don't consider the concept of field carcinogenesis. In fact, it is probable that near or far from an excised precancerous lesion new foci of cell transformation may exist, which are not yet macroscopically evident, but, if detected, would put the patient into a high risk subgroup.Comparing findings reported in the recent literature, the data of this state of the art about HPV might add useful informations concerning oropharyngeal carcinogenesis. Moreover, our review would be useful in order to define novel perspectives of treatment choice for Head & Neck cancer patients, by combining well known chemotherapeutical drugs with new molecular "target" therapy.

Abstract
The aim of the study was to investigate the role of high-risk human papillomavirus (HR-HPV) infection in the etiopathogenesis of oral (OSCC) and oropharyngeal (OPSCC) squamous cell carcinoma in non-smoking and non-drinking patients (NSNDP). Twenty-four OSCCs and 22 OPSCCs were analyzed by immunohistochemistry for p16(INK4a) protein (p16) expression and by chromogene in situ hybridization (CISH) and polymerase chain reaction (PCR) for HR-HPV DNA presence. The series included 23 males and 23 females aged 35-93 years. p16 expression was seen in 7 out of 24 (29%) OSCCs and in 22 out of 22 (100%) OPSCCs. Using CISH, HR-HPV DNA was observed in 6 out of 24 (25%) OSCCs and in 21 out of 22 (95%) OPSCCs. HPV DNA was found in 3 out of 24 (13%) OSCCs and in 18 out of 22 (82%) OPSCCs using PCR. HPV 16 and 33 were detected in 16 and in two cases, respectively. Compared with OSCCs, OPSCCs more frequently showed basaloid morphology (p < 0.0001), lymph node involvement (p = 0.0063), diffuse p16 expression (p < 0.0001), HR-HPV DNA presence using both CISH and PCR (p < 0.0001; p < 0.0001), and better outcome. The sensitivity and specificity of p16 expression for HR-HPV DNA presence detected by CISH were 0.89 and 0.95, respectively, and 0.95 and 0.85 for PCR detected HPV DNA. The sensitivity and specificity of CISH for PCR detected presence of HPV DNA were 1.00 and 0.73, respectively. Our study is the first larger study analyzing OSCC and OPSCC in NSNDP. Our results indicate that unlike OSCC, a vast majority of OPSCCs may be associated with HR-HPV infection.

Abstract
Human papillomavirus type 16 (HPV-16) has been established beyond doubt as a causative agent in oropharyngeal squamous cell carcinoma (SCC). The incidence of oropharyngeal cancer has risen in recent decades, as has the proportion of patients who have a biologically relevant HPV-16 infection. Combined data from 14 recently published studies (2006-2010) show that 57% of 1316 reported cases of oropharyngeal SCC were HPV-16 positive. They had significantly better prognosis (hazard ratio (HR) for 5-year overall survival range 0.05-0.64), although smoking and higher T stage often appear as confounding factors to this favourable prognostic benefit. HPV-16 therefore has increasing importance as a clinically useful prognostic biomarker, but a benefit in survival has been seen in the use of surgery, radiotherapy, and chemotherapy, so specific changes in the preferred methods of treatment are hard to justify. Future trials that include oropharyngeal SCC will consider HPV-16 routinely as a stratification factor, and its use as a predictive biomarker awaits the development of effective targeted treatments. The undeniable and impressive prognostic significance of HPV-16 should hasten its addition to standard pathological reporting of oropharyngeal SCC, and ultimately to its inclusion in TNM staging systems of the American Joint Committee on Cancer (AJCC) and the International Union against Cancer (UICC).

Abstract
A rise in incidence of oropharyngeal squamous cell cancer--specifically of the lingual and palatine tonsils--in white men younger than age 50 years who have no history of alcohol or tobacco use has been recorded over the past decade. This malignant disease is associated with human papillomavirus (HPV) 16 infection. The biology of HPV-positive oropharyngeal cancer is distinct with P53 degradation, retinoblastoma RB pathway inactivation, and P16 upregulation. By contrast, tobacco-related oropharyngeal cancer is characterised by TP53 mutation and downregulation of CDKN2A (encoding P16). The best method to detect virus in tumour is controversial, and both in-situ hybridisation and PCR are commonly used; P16 immunohistochemistry could serve as a potential surrogate marker. HPV-positive oropharyngeal cancer seems to be more responsive to chemotherapy and radiation than HPV-negative disease. HPV 16 is a prognostic marker for enhanced overall and disease-free survival, but its use as a predictive marker has not yet been proven. Many questions about the natural history of oral HPV infection remain under investigation. For example, why does the increase in HPV-related oropharyngeal cancer dominate in men? What is the potential of HPV vaccines for primary prevention? Could an accurate method to detect HPV in tumour be developed? Which treatment strategies reduce toxic effects without compromising survival? Our aim with this review is to highlight current understanding of the epidemiology, biology, detection, and management of HPV-related oropharyngeal head and neck squamous cell carcinoma, and to describe unresolved issues.

Abstract
Over the last 20 years, there has been increasing awareness of a subset of squamous cell carcinomas of the head and neck (HNSCC), i.e. HPV-positive HNSCC. These cancers seem to differ somewhat from HPV-negative HNSCC. Patients with HPV-positive HNSCC tend to be younger and have a lower intake of tobacco and alcohol. Distinct molecular profiles separate them from HPV-negative cancers and show similarities with HPV-positive cervical SCC. There is evidence that HPV-positive HNSCC is a sexually transmitted disease. Patients with HPV-positive HNSCC are often diagnosed at a late stage with large cystic lymph nodes in the neck. HPV-positive HNSCC show an affinity for the oropharynx, especially the tonsils and the base of the tongue, and tend to show low differentiation histopathologically. There is a better prognosis regardless of the treatment regimen for HPV-positive HNSCC compared with HPV-negative HNSCC, and this seems to be related to the immune system. Whether the new vaccines for HPV will protect not only against cervical cancer but also against HPV-positive HNSCC remains unknown.

Abstract
BACKGROUND Human papillomavirus (HPV) is a causative agent in a subset of head and neck squamous cell carcinomas (HNSCCs). These HPV-related cancers have a clinicopathologic profile that diverges from HPV-negative HNSCCs. Accordingly, HPV testing may soon become integrated into standard pathologic assessment of HNSCCs. METHODS Data were prospectively collected for all patients with head and neck carcinomas who had undergone HPV testing at the Johns Hopkins Hospital as part of clinical care during a 57-month period. HPV testing consisted of concurrent HPV16 in situ hybridization (ISH) and p16 immunohistochemistry (IHC). Wide spectrum HPV ISH was reserved for p16-positive cases that were HPV-16 negative. RESULTS HPV analysis was performed on 256 head and neck carcinomas in an effort to predict clinical outcomes (56%), localize primary tumor origin (21%), establish tumor classification (9%), determine patient eligibility for vaccine trials (8%), or satisfy patient curiosity (5%). A total of 182 (71%) tumors were HPV positive. HPV positivity correlated with oropharyngeal site (82% vs 9%) and male sex (77% vs 48%). p16 positivity was present in all 176 HPV16-positive cases, and in 19 of 80 (24%) cases that were HPV-16 negative. In 6 (32%) discordant cases, p16 expression was because of the presence of another HPV type. CONCLUSIONS A feasible strategy that incorporates p16 IHC and HPV ISH is able to detect HPV in a high percentage of oropharyngeal carcinomas. HPV status is frequently requested by the oncologist to estimate clinical outcome, and used by pathologists to establish tumor classification and determine site of tumor origin.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is an aggressive malignancy with more than half a million people being diagnosed with the disease annually. Within the last 2 decades, the human papillomavirus (HPV) has been found to be associated with this malignancy. More recently, HPV-infected HNSCC has been found to exhibit higher levels of global DNA methylation. In a recent study, we identified five tumor suppressive genes (IRX1, EBF3, SLC5A8, SEPT9, and FUSSEL18) as frequently methylated in HNSCC biopsies using a global methylation analysis via restriction landmark genomic scanning. In this study, we verify these genes as valid methylation markers in two separate sets of HNSCC specimens. By using the available clinical information linked to the patient specimens, we found a strong association between promoter methylation of FUSSEL18, IRX1, and EBF3 and prior radiation therapy (P < 0.0001) irrespective of HPV status. Also, promoter methylation of FUSSEL18 and SEPTIN9 was found to correlate significantly with exposure to alcohol and tobacco (P = 0.021). Importantly, in this study, we preliminarily show a trend between HPV16 positivity and specific target gene hypermethylation of IRX1, EBF3, SLC5A8, and SEPT9. If replicated in a larger study, the HPV status may be a patient selection biomarker when determining the most efficacious treatment modality for these different subsets of patients (e.g., inclusion or exclusion of epigenetic therapies). Equally notable and independent of HPV status, hypermethylation of the promoters of a subset of these genes in recurrences especially in the setting of prior radiation or in the setting of alcohol and tobacco use might help guide adjunctive inclusion or exclusion or epigenetic therapy.

Abstract
Molecular diagnostic techniques are quickly finding a role in the detection and diagnosis of tumors, and in predicting their behavior. They may also prove useful in developing new therapeutic approaches to head and neck cancer. The surgeon working in the craniomaxillofacial region should have an understanding of these technologies, their availability in various settings, and how they affect various aspects of treatment, particularly in the detection and treatment of malignancies. This article offers an overview of recent advances in molecular diagnostic techniques, with their implications for diagnosis and management of head and neck tumors.

Abstract
BACKGROUND Increasing evidence shows that Human Papillomavirus (HPV) is preferentially associated with some head and neck squamous cell carcinomas (HNSCCs), with variable infection rates reported. METHODS We assessed HPV involvement in HNSCC using the Roche Linear Array HPV Genotyping Test, which can detect 37 different HPV types. We examined the prevalence of HPV infection in 92 HNSCCs (oropharynx, oral cavity, and other HNSCC sites). RESULTS HPV was frequently detected in oropharyngeal cancers (OPCs) (16/22, 73%), but was uncommon in oral cavity cancers (2/53, 4%), and in other HNSCC subsites (1/17, 6%). HPV positive tumors were associated with patients that were 40-60 years old (p = 0.02), and node positive (p = < 0.0001). HPV 16 was the most prevalent type, but other types detected included 6, 18, 33, 35, 45, and 52/58. CONCLUSION Our results show that in contrast to oropharyngeal cancers, oral cancers and other HNSCCs infrequently harbor HPV.
