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
BACKGROUND The purpose of this study was to characterize the expression of CD200, a membrane protein that functions in immune evasion, to examine its correlations with cancer stem cell (CSC)-like features and analyze its response to chemotherapy and radiation in human papillomavirus (HPV)-positive (+) and negative (-) head and neck squamous cell carcinomas (HNSCCs). METHODS CD200 expression was analyzed in several HNSCC cell lines. CD200 was overexpressed in HPV(+) murine tonsil epithelial cells, its effects on Shh and Bmi-1 were examined in vitro, and tumor growth and response to chemoradiation were analyzed in vitro and in vivo. RESULTS CD200 was diversely expressed and consistently associated with expression of Bmi-1 and Shh. Overexpression of CD200 induced Bmi-1 and Shh. Tumors grew similarly between C57BL/6 and Rag1(-/-) C57BL/6 mice. CD200 expression enhanced the resistance to chemoradiation only in vivo. CONCLUSION CD200 was related to CSC features and modulates response to chemoradiation in vivo. Attenuating this might be a potential therapeutic strategy.

Abstract
OBJECTIVES Epidemiological research indicates an association between the Human Papillomavirus (HPV) with a subset of oral cancers (OC). Dentists may play a role in primary prevention of HPV-related OC by discussing the HPV vaccine with patients. This study assessed dentists' readiness to discuss the HPV vaccine with female patients. STUDY DESIGN Cross-sectional web-based survey. METHODS A web-based survey based on the Transtheoretical Model was administered among Florida dentists (n = 210). RESULTS The majority of participants (97%) fell into the precontemplation and contemplation stages of readiness to discuss the HPV vaccine with patients. Perceived role and liability were determined to be predictive of dentists in contemplation stage as opposed to those in precontemplation (P < 0.05). CONCLUSIONS Findings suggest liability and perceived role as processes of change necessary to guide dentists to primary prevention of HPV-related OC despite high levels of knowledge. As public awareness of HPV-related OC increases, dentists may become more involved in primary prevention. Results of the current study may assist in developing intervention strategies for engaging dentists in discussing the HPV vaccine with patients.

Abstract
BACKGROUND Human papillomavirus (HPV) infection might be one of the potential risk factors for oesophageal cancer. However, the previous epidemiological findings were heterogeneous. AIM To explore the association between HPV infection and oesophageal cancer risk by means of meta-analysis. METHODS Studies on HPV infection and oesophageal cancer were identified, the prevalence of HPV infection and its association with oesophageal cancer risk were quantitatively summarised by meta-analysis. RESULTS A total of 8990 oesophageal squamous cell carcinoma (SCC) patients and 174 oesophageal adenocarcinomas patients were evaluated from 76 included studies. Summarised HPV prevalence in oesophageal SCC was 22.2% [95% confidence interval (CI), 18.3-26.7%], HPV-16 was the most frequently observed subtype with a summarised prevalence of 11.4% (95% CI: 8.2-15.7%). With respect to oesophageal adenocarcinoma, HPV prevalence was 35.0% (95% CI, 13.2-65.7%) and HPV-16 prevalence was 11.4% (95% CI: 8.2-15.7%). Due to the limited number of included studies on oesophageal adenocarcinoma, association analyses were performed to oesophageal SCC only. Significant association was observed between HPV infection and oesophageal SCC with a summarised odds ratio of 3.32 (95% CI, 2.26-4.87). According to HPV-16, the strength of the association was found to be 3.52 (95% CI, 2.04-6.07). CONCLUSIONS Human papillomavirus infection was observed to be associated with an increased risk of oesophageal SCC in this meta-analysis. However, due to the evident heterogeneity observed between the included studies and the strength of the association not as strong as observed for cervical cancer and laryngeal cancer, further studies are needed to clarify the relation and its underlying mechanisms.

J Oral Maxillofac Surg 2014; 72:1291-300. [PMID: 24813775 DOI: 10.1016/j.joms.2014.01.009] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2013] [Revised: 01/06/2014] [Accepted: 01/09/2014] [Indexed: 01/09/2023]
Abstract
PURPOSE To analyze clinicopathologic parameters of oral squamous cell carcinoma (OSCC) in different age groups. We hypothesized that clinical and pathologic parameters of OSCCs will vary in different age groups. MATERIALS AND METHODS A retrospective cohort study was performed. All patients who were treated for a primary manifestation of OSCC at a single institution from 2001 to 2012 were reviewed and allocated to predefined age groups (predictor variable) as follows: young (≤40 years), middle-aged (40-80 years), and very elderly (≥80 years). The following outcome variables were recorded: demographic parameters, classic risk factors, tumor location and size, neck node involvement, histopathologic and therapeutic details, and association with human papillomavirus (HPV). The descriptive statistics were computed. Parametric and nonparametric tests were used for additional analysis. The significance level was set at P < .05. RESULTS We reviewed 739 patients and identified 11 (1.4%) young (mean age 34.2 ± 2.8 years) and 17 (2.3%) very elderly patients (mean age 83.1 ± 1.2 years). The predilection site for OSCC was the oral tongue (63%) in young patients, the floor of the mouth (52%) in middle-aged patients, and the alveolar process (60%) in very elderly patients. One patient in the young group (9%) and 8 patients in the very elderly group (47%) had been exposed to risk factors; however, all of the examined middle-aged patients had had such exposure. The association of OSCC with HPV was distributed equally among the age groups. No age-related differences in the histopathologic parameters of OSCC were found. CONCLUSIONS The features of OSCC that vary at different ages are the anatomic predilection site and the association with classic risk factors. HPV was not an age-related independent risk factor for OSCC development in the present study.

Abstract
BACKGROUND Human papillomavirus (HPV)-positive oropharyngeal cancer (OPSCC) is associated with improved survival compared with HPV-negative disease. However, a minority of HPV-positive patients have poor prognosis. Currently, there is no generally accepted strategy for identifying these patients. METHODS We retrospectively analysed 270 consecutively treated OPSCC patients from three centres for effects of clinical, pathological, immunological, and molecular features on disease mortality. We used Cox regression to examine associations between factors and OPSCC death, and developed a prognostic model for 3-year mortality using logistic regression analysis. RESULTS Patients with HPV-positive tumours showed improved survival (hazard ratio (HR), 0.33 (0.21-0.53)). High levels of tumour-infiltrating lymphocytes (TILs) stratified HPV-positive patients into high-risk and low-risk groups (3-year survival; HPV-positive/TIL(high)=96%, HPV-positive/TIL(low)=59%). Survival of HPV-positive/TIL(low) patients did not differ from HPV-negative patients (HR, 1.01; P=0.98). We developed a prognostic model for HPV-positive tumours using a 'training' cohort from one centre; the combination of TIL levels, heavy smoking, and T-stage were significant (AUROC=0·87). This model was validated on patients from the other centres (detection rate 67%; false-positive rate 5.6%; AUROC=0·82). INTERPRETATION Our data suggest that an immune response, reflected by TIL levels in the primary tumour, has an important role in the improved survival seen in most HPV-positive patients, and is relevant for the clinical evaluation of HPV-positive OPSCC.

Abstract
BACKGROUND Oral and cervical cancers are major malignancies in men and women, respectively, in India. This study evaluated occurrence of human papillomavirus (HPV) 16 and 18 infections in oral and cervical cancers to estimate HPV-associated burden of these cancers in the population from Gujarat, West India. METHODS A total of 97 malignant oral carcinoma tissues and 52 cervical carcinoma tissues were analyzed by type-specific PCR for the presence of HPV type 16 and 18 infections. RESULTS None of the oral cancer patients revealed the presence of HPV type 16 and 18 infection. In cervical cancer, 31 (59.6%) patients were infected with HPV 16 and 18. Of these 31 HPV-positive cervical cancer patients, 28 (90.3%) were infected with HPV 16 and 3 (9.7%) were infected with HPV 18. CONCLUSION The results suggested that HPV 16 and 18 do not play an important role in oral carcinogenesis in the population from Gujarat, West India. However, HPV 16 is highly prevalent in the cervical cancer patients, which may be considered for planning of prevention programs such as screening and vaccination in women from this region.

Abstract
Head and neck squamous cell carcinoma (HNSCC) includes both morphological and functional cellular heterogeneity, as would be expected if it arose from dysregulated stem or progenitor cells as opposed to the simple clonal expansion of a mutated cell; however, stemness molecule expression levels and distribution in HNSCC remain unclear. To clarify this, stemness molecule expressions were determined in HNSCC, as well as their properties and prognosis. Two proto-oncogenic chromatin regulators, Bmi-1 and high-mobility-group A2 (Hmga2), were identified in 12 pair cases of HNSCC tumor regions by comparison with their non-cancerous background tissues using cDNA microarray. Both Bmi-1 and Hmga2 are known to promote stem cell self-renewal by negatively regulating the expressions of Ink4a and Arf tumor suppressors. Despite similar targets, Bmi-1 protein was expressed in an early cancerous region and HMGA2 protein was expressed in a region showing more progression. Similarly, Bmi1 expression had no significance with regard to overall survival (P=0.67), whereas HMGA2 expression was associated with decreased overall survival (P=0.05). Quantitative real-time reverse transcription polymerase chain reaction analyses also correlated with protein levels. These findings suggest that Bmi-1 is an early detection marker to distinguish cancerous from non-cancerous regions, whereas HMGA2 is presumed to be a tumor prognosis marker. Among our HNSCC analyses, these stemness molecules expressed fewer primitive rare cells in the tumor than all other cells in the tumor. HNSCC cells with high expression of stemness molecules partly behave like stem cells.

Abstract
Genomic instability underlies the transformation of host cells toward malignancy, promotes development of invasion and metastasis and shapes the response of established cancer to treatment. In this review, we discuss recent advances in our understanding of genomic stability in squamous cell carcinoma of the head and neck (HNSCC), with an emphasis on DNA repair pathways. HNSCC is characterized by distinct profiles in genome stability between similarly staged cancers that are reflected in risk, treatment response and outcomes. Defective DNA repair generates chromosomal derangement that can cause subsequent alterations in gene expression, and is a hallmark of progression toward carcinoma. Variable functionality of an increasing spectrum of repair gene polymorphisms is associated with increased cancer risk, while aetiological factors such as human papillomavirus, tobacco and alcohol induce significantly different behaviour in induced malignancy, underpinned by differences in genomic stability. Targeted inhibition of signalling receptors has proven to be a clinically-validated therapy, and protein expression of other DNA repair and signalling molecules associated with cancer behaviour could potentially provide a more refined clinical model for prognosis and treatment prediction. Development and expansion of current genomic stability models is furthering our understanding of HNSCC pathophysiology and uncovering new, promising treatment strategies.

Abstract
Background: Head and neck squamous cell carcinoma is often associated with human papillomavirus (HPV) infection. Positive HPV status has been associated with increased response to treatment and improved prognosis in terms of recurrence-free and overall survival. In certain instances, diagnosis is performed through fine-needle aspiration of lymph nodes with metastatic carcinoma, often demonstrating extensive tumor necrosis. We evaluated the effect of tumor necrosis on deoxyribonucleic acid (DNA) adequacy for HPV molecular testing. Materials and Methods: Retrospective review of the pathology files at our institution identified cases of squamous cell carcinoma (SCC) diagnosed by fine-needle aspiration (FNA) on which HPV DNA molecular testing was performed. The cases were classified according to percent tumor necrosis into three categories (<10% necrosis, 10-70% necrosis and >70% necrosis) and the percentage of cases with adequate HPV DNA for molecular testing in each of the categories was compared. When available, p16 immunohistochemistry performed on the cases was compared with HPV status by molecular testing. Results: A total of 70 cases from 67 patients were included in the study. Adequate DNA for molecular HPV testing was obtained from samples of 47 cases (67%) while samples from 23 cases (33%) were inadequate for molecular testing. Of the adequate samples, 36 (77%) were positive and 11 (23%) were negative for high-risk HPV. Adequate DNA for testing was obtained in 22 out of 33 cases showing no necrosis (67%), 10 out of 16 cases showing partial necrosis (63%) and in 13 out of 17 cases showing extensive necrosis (76%). Conclusion: Our study found that HPV molecular testing is not influenced by percent tumor necrosis or method by which FNA was performed. We believe that a portion of the FNA specimen obtained from head and neck lesions diagnosed as SCC during the rapid on-site evaluation should be sent for HPV DNA testing, independent of the amount of tumor necrosis, thus guaranteeing availability of specimen for HPV testing.

[PMID: 24169585 DOI: 10.1016/j.oraloncology.2013.10.008] [Citation(s) in RCA: 60] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2013] [Revised: 10/03/2013] [Accepted: 10/08/2013] [Indexed: 10/26/2022]
Abstract
High risk Human Papilloma virus (HR-HPV) associated oropharyngeal cancers are on the increase. Although, the scientific community is aware of the importance of Human Papilloma Virus (HPV) testing, there is no consensus on the assays that are required to reliably identify HR-HPV related tumors. A wide range of methods have been developed. The most widely used techniques include viral DNA detection, with polymerase chain reaction (PCR) or In Situ Hybridization, and p16 detected by immunohistochemistry. However, these tests provide different information and have their own specific limitations. In this review, we summarize these different techniques, in light of the recent literature. p16 Overexpression, which is an indirect marker of HPV infection, is considered by many head and neck oncologists to be the most important marker for patient stratification. We describe the frequent lack of concordance of this marker with other assays and the possible reasons for this. The latest developments in HPV testing are also reported, such as the RNAscope™ HPV test, and how they fit into the existing framework of techniques. HPV testing must not be considered in isolation, as there are important interactions with other parameters, such as tobacco exposure. This is an important and rapidly evolving field and is likely to become pivotal to staging and choice of treatment of oropharyngeal carcinoma in the future.

Abstract
Since p14 (ARF) and human papillomavirus (HPV) 16 E6/E7 oncoproteins are important regulators participating in the p53/Rb pathways, genetic variations of p14 (ARF) may modify tumor HPV16 status and survival of HPV16-positive squamous cell carcinoma of the oropharynx (SCCOP) patients. We determined tumor HPV16 status and expression of p14/p53 and genotyped p14 (ARF) -rs3731217 and -rs3088440 polymorphisms in 552 incident SCCOP patients. We found that patients having variant genotypes for each p14 (ARF) polymorphism were approximately two or three times as likely to have HPV16-positive tumors compared with patients with corresponding common homozygous genotype, and such an association was particularly pronounced in patients with variant genotypes of both polymorphisms. After definitive chemoradiotherapy, patients having p14 (ARF) rs3731217 TG/GG variant genotypes had significantly better overall, disease-specific and disease-free survival than those having TT genotype, respectively. Multivariable analysis found that patients with p14 (ARF) -rs3731217 TT genotype had an ~7-, 11- and 3-fold increased risk for death overall, death due to SCCOP and recurrence than those with TG/GG variant genotypes, respectively. Furthermore, such significantly prognostic effect was also found when survival analysis was limited to HPV16-positive patients. Additionally, potentially functional relevance of the two variants was characterized to explore the genotype-phenotype correlation. Our findings indicate p14 (ARF) variants may predict tumor HPV16-positive SCCOP patients and survival.

Abstract
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
OBJECTIVES/HYPOTHESIS The incidence of human papillomavirus (HPV)-positive head and neck cancers (HNCs) is increasing sharply worldwide, while their HPV-negative counterparts are showing a decreased frequency. However, epidemiologic data related to these changes are sparse in Korea, which is rapidly adopting more westernized lifestyles. STUDY DESIGN Data from the Korea Central Cancer Registry, a nationwide population-based cancer registry, from 1999 to 2009 were retrieved. METHODS Age-standardized rates (ASRs), their annual percent changes (APC) and male-to-female incidence rate ratios (IRRs) were analyzed and compared between HPV-related and HPV-unrelated primary sites. RESULTS HPV-related sites (oropharynx) had increased significantly over the period 1999 to 2009 (APC = 2.35%, P = 0.017), particularly in young men (30-59 years, APC = 2.65%, P = 0.031), whereas HPV-unrelated sites such as larynx and hypopharynx decreased markedly in both sexes. Interestingly, tongue cancer was found to have increased gradually (APC = 2.35%, P = 0.003) in both sexes. The male-to-female IRRs and the median age of occurrence remained stable. CONCLUSIONS Although the cultural and ethnic background differs from the United States, cancers of HPV-related sites are increasing in Korea, whereas cancers of HPV-unrelated sites are decreasing, which is similar to the trends observed in the United States. Greater public awareness in Korea of HPV-related HNCs is therefore warranted.

Abstract
Human papillomavirus (HPV) constitutes the majority of newly acquired sexually transmitted infections (STIs) in United States as per the centers for disease control factsheet 2013. Genital HPV is the most common STI with incidence of about 5.5 million world-wide, nearly 75% of sexually active men and women have been exposed to HPV at some point in their lives. Oral Sexual behavior is an important contributor to infection of HPV in the oral mucosa especially in cases known to practice high risk behavior and initiating the same at an early age. HPV infection of the oral mucosa currents is believed to affect 1-50% of the general population, depending on the method used for diagnosis. The immune system clears most HPV naturally within 2 years (about 90%), but the ones that persist can cause serious diseases. HPV is an essential carcinogen being implicated increasingly in association with cancers occurring at numerous sites in the body. Though there does not occur any specific treatment for the HPV infection, the diseases it causes are treatable such as genital warts, cervical and other cancers.

Evidence that alpha-9 human papillomavirus infections are a major etiologic factor for oropharyngeal carcinoma in black South Africans. Head Neck Pathol 2013; 7:361-72.

Abstract
Human papillomavirus (HPV) infection, most commonly genotype 16 of the alpha-9 family, is implicated in the etiology of a subset of oropharyngeal squamous cell carcinomas (OPSC) worldwide. Data are scarce regarding OPSC in South Africans, and three prior studies suggest no significant etiologic role for HPV. We aimed to investigate for evidence of HPV etiology in OPSCs from black South Africans by polymerase chain reaction (PCR) methodologies with determination of HPV subtype by sequencing, in situ hybridization (ISH), and p16INK4a immunohistochemistry (IHC), as a surrogate marker for an HPV-driven tumor. It was hypothesized that HPV-driven tumors would be positive by PCR plus IHC and/or ISH whereas OPSCs with HPV background infections (HPV-passenger) would be positive by PCR alone. Formalin-fixed, paraffin embedded tissues from 51 OPSCs collected between 2005 and 2010 from 41 patients were analyzed for HPV by GP5?6? PCR (targeting the HPV L1 region), pU-1M/pU- 2R PCR (targeting the HPV E6/E7 region) and HPV-31 specific PCR (targeting the E5 region), chromogenic ISH, and p16INK4a IHC. All cases positive by PCR were subject to sequencing to determine HPV genotype. The patient mean age was 58.0 years and 88 % were male. Of the 51 evaluable tumors, 48 (94.1 %) were positive for HPV DNA by PCR: 25 (49.1 %) met criteria for an HPV-driven tumor, 23 (45.1 %) for HPV-passenger, and 3 (5.9 %) were HPV unrelated. Sequencing of the PCR-positive cases revealed the following genotypes: combined HPV-16 and 31 (41.7 %), HPV-31 (25.0 %), HPV-16 (22.9 %), combined HPV-16 and 18 (6.3 %), and a single case each of HPV 18 and HPV 33. Studies via ISH were negative in all cases. In accordance with worldwide trends but contrary to prior South African data, HPV likely plays an etiologic role in a significant subset (at least 49.1 %) of OPSC in black South Africans. We found that the alpha-9 HPV family, particularly HPV-16 and 31 either in combination or separately, to predominate in our sample tumors. The use of multiple PCR primers increased sensitivity of viral detection, and a HPV-31 specific primer confirmed the presence of this genotype in many samples. Further studies including HPV E6/E7 mRNA assays are needed to better elucidate the pathogenic role of HPV in black South African OPSCs.

Abstract
The incidence of oropharyngeal cancer and oral cancer is growing worldwide, both in young non-smokers and in young non-drinkers (smoking and drinking are considered the main risk factors). Epidemiologic studies suggest a strong association between the infection by human papillomavirus (HPV), especially types 16 and 18 (high oncological risk) which have already demonstrated their etiological role in anal tumours as well as in cervix cancer. There is clear epidemiologic evidence that both types of tumours relate to changes in sexual behaviour and that both are linked to sexual transmission of HPV. The number of oral and oropharyngeal cancer cases is rising nowadays, especially among young individuals with no typical toxic habits, such as tobacco and/or alcohol.
In this review we set out to update the aspects related to the onset of oral cancer, its relationship with HPV infection and whether this association may be due to the sexual transmission of the virus.

Abstract
OBJECTIVES The study evaluated pathognomic histopathological features with the help of light microscopy for detecting the integration of human papillomavirus (HPV) (type 16 and 18) in oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS Forty-five histopathologically diagnosed cases of OSCC were evaluated for the presence of E6/E7 protein of HPV (16 + 18) with the help of nested multiplex polymerase chain reaction. Both HPV-positive and -negative cases were evaluated for four histological features: Koilocytes, dyskeratosis, invasion, and alteration of collagen. RESULTS Fischer's exact test showed significant difference (P < 0.01%) for the presence of koilocytes and dyskeratosis, whereas no difference was observed for invasion and alteration in collagen between HPV-positive and -negative OSCC. CONCLUSION The presence of koilocytes and dyskeratosis at light microscopic level can be used as a marker for the presence of HPV (type 16 and 18) in OSCC.

Abstract
Infection with human papilloma virus (HPV) has been associated with head and neck carcinomas. Experts in HPV-positive carcinomas consider these carcinomas to be a new entity, because it has been shown that treatment outcome is excellent with significantly longer overall survival dependent of therapy. Despite this, in Germany public awareness of this development is rather low. A strategy for prophylactic vaccination against HPV-associated diseases has been available since 2007 but only to reduce the incidence of cervical cancer for girls between 12 and 17 years of age. There is an ongoing debate in Germany about the efficacy and safety of HPV vaccination. The results of epidemiological research in the USA which show that vaccination in young males is valuable are still not accepted in Germany. This article discusses the scientific and public awareness regarding this topic and calls for precision in diagnostics and public health awareness in order to establish a fertile ground for prevention and optimal treatment of HPV-associated diseases.

Abstract
OBJECTIVE To analyse the association between high-risk human papillomavirus (HR-HPV) and other risk factors in the aetiology of head and neck squamous cell carcinoma (HNSCC) in an Asian population. STUDY DESIGN This study is a cross-sectional analysis of 80 patients who were diagnosed with HNSCC. Patients' demographics, dietary habit, medical and social history were obtained. Surgical specimens from these patients were then histologically analysed using H&E stain and immunohistochemistry (IHC) for the presence of HR-HPV primary antibody. RESULTS High-risk human papillomavirus was detected in 41 patients, representing 51.3% of the 80 paraffin-embedded tissues of HNSCC; 27.5% of these were weak positive, 10.0% medium positive and 13.8% were strongly positive for the HR-HPV on IHC. The tongue lesions had the highest HR-HPV infection of 72.2%. No association existed between HR-HPV and patient's demographics, dietary habit and other predisposing factors. CONCLUSION The place of HR-HPV as a possible aetiological factor for HNSCC has further been established from this study.

Abstract
PURPOSE Epigenetic alterations of the transcription factor 21 (TCF21) gene have been associated with head and neck squamous cell carcinoma (HNSCC) and other tumor entities. So far, however, no reports have appeared in the literature on TCF21 protein expression in HNSCC and its relevance as a putative biomarker. METHODS TCF21 protein expression was assessed in 74 HNSCCs and 31 benign tonsils by immunohistochemistry. Methylation analyses of the corresponding gene promoter were performed in 45 HNSCCs and 31 benign tonsils. The TCF21 expression levels in the tumors and controls were compared with each other and within each group and, in addition, with the TCF21 promoter methylation status and various clinicopathological characteristics. RESULTS Overall, both the expression levels and methylation frequencies of TCF21 were significantly higher in the HNSCCs than in the benign controls (p < 0.001 each). Specifically, TCF21 promoter hypermethylation resulted in a reduced protein expression in a subgroup of the HNSCCs (p = 0.038), but not in the tonsils. In the tonsils, TCF21 protein expression positively correlated with that of CD31 (p = 0.039), a marker for blood vessels. Also, in the tonsils the TCF21 protein methylation frequency showed a positive correlation with age (p = 0.008). The HNSCCs of patients with a positive history for alcohol and nicotine abuse showed higher TCF21 protein expression levels than their respective counterparts (p = 0.028 and p = 0.062, respectively). The same was observed in human papilloma virus (HPV)-negative tumors (p = 0.042), tumors located in the oral cavity (p = 0.016) and early-stage tumors (p = 0.025). Interestingly, expression rates in tumors of the oropharynx, where HPV-positive tumors were most frequently found, tended to be lower (p = 0.065). The methylation frequencies of TCF21 were found to be significantly higher in tumors of patients without nicotine abuse (p = 0.030), in HPV-positive tumors (p = 0.014) and in tumors exhibiting over-expression of p16, a protein induced by HPV (p = 0.006). CONCLUSIONS Both over-expression and increased promoter methylation of TCF21 were frequently observed in HNSCCs. TCF21 promoter hypermethylation was found to lead to gene silencing in the HNSCCs, but not in the benign tonsils. These epigenetic, and possibly also genetic, alterations of the TCF21 gene in HNSCCs may be driven by HPV infection, nicotine and alcohol abuse, or both. These findings, together with its stage- and primary site-dependent expression, turn TCF21 into a promising candidate biomarker in HNSCC.

Abstract
BACKGROUND The causal link between cervical cancer and human papilloma virus (HPV) is well known. It is now becoming clear that some types of squamous-cell carcinoma of the head and neck, particularly oropharyngeal carcinoma (OPC), are also linked to HPV infection. The development of vaccines against certain HPV genotypes has changed the management strategy for HPV-associated diseases of the uterine cervix. An analogous approach is now being considered for the prevention of HPV-associated diseases of the head and neck. METHOD We review pertinent articles retrieved by a selective search of the literature for phase II and III trials providing evidence about a possible effect of HPV status on the survival rates of patients with OPC. Seven trials fulfilled our search criteria: four phase III trials with retrospective HPV analysis and three phase II trials with retrospective and prospective HPV analysis. RESULTS Patients with HPV-positive OPC survive significantly longer than those with HPV-negative OPC. Tobacco smoking has been identified as a negative prognostic factor in patients with either HPV-negative or HPV-positive disease. CONCLUSION The established treatment strategy for OPC in patients with and without the traditional risk factors (tobacco and alcohol consumption) is now being reconsidered in the light of what we have learned about the role of HPV infection. Ongoing and projected clinical trials with risk-factor stratification may soon lead to changes in treatment. Further study is needed to answer the question whether HPV infection in the head and neck region is carcinogenic.

Abstract
Human papillomavirus (HPV)-related head and neck squamous cell carcinoma (HNSCC)
is considered to be a distinct clinical entity with better prognosis than the
classical tobacco- and alcohol-associated tumors. The increasing incidence of
this neoplasia during the last decades highlights the need to better understand
the role of HPV in the development of these cancers. Although the proportion of
HNSCC attributed to HPV varies considerably according to anatomical site,
overall approximately 25% of all HNSCC are HPV-DNA positive, and HPV-16 is by
far the most prevalent type. In this review we discuss the existing evidence for
a causal association between HPV infection and HNSCC at diverse anatomical head
and neck subsites.

Abstract
We previously showed that secretory leukocyte protease inhibitor (SLPI) gene and protein expression is significantly lower in metastatic versus non-metastatic head and neck squamous cell carcinoma (HNSCC). However, we did not assess the human papillomavirus (HPV) status of these cases. Since SLPI plays a role in HIV and herpes simplex virus (HSV) infections, we hypothesized that SLPI may be involved in HPV-infected HNSCC. In HNSCC tissue (n=54), HPV DNA was determined and correlated with SLPI expression. Additionally, to investigate a possible role of smoking on SLPI expression in clinically normal mucosa, 19 patients treated for non-malignant diseases (non-HNSCC) were analyzed for SLPI expression and correlated with smoking habits. In HNSCC patients, SLPI expression showed a significant inverse correlation with HPV status. In patients with moderate/strong SLPI expression (n=19), 10.5% were HPV-positive. By contrast, patients with absent/weak SLPI expression (n=35), 45.7% were HPV-positive. Low SLPI expression was correlated with metastasis (P=0.003) independent of HPV status. HPV-positivity was clearly associated with lymph node status (81.3% N1-3 cases). In smoking non-HNSCC patients (n=7), 42.9% showed absent/weak and 57.1% moderate/strong SLPI staining. In non-smoking non-HNSCC patients (n=10) 83.3% showed absent/weak and 16.7% moderate/strong SLPI expression. For the first time, a correlation between SLPI downregulation and HPV infection was demonstrated, suggesting that high levels of SLPI, possibly induced by environmental factors such as tobacco smoking, correlate with protective effects against HPV infection. SLPI may be a potential biomarker identifying head and neck cancer patients not at risk of developing metastases (SLPI-positive), and those at risk to be infected by HPV (SLPI-negative) and likely to develop metastases.

Abstract
Background Human papillomavirus (HPV)-related head and neck cancer has been associated with an improved prognosis in patients treated with radiotherapy (RT) +/− chemotherapy (CT); however, RT combined with epidermal growth factor receptor (EGFR) inhibitors has not been fully studied in this group of patients. Methods Immunohistochemical expression of p16 and PCR of HPV16 DNA were retrospectively analyzed in tumor blocks from 108 stage III/IV head and neck cancer patients treated with RT+CT (56) or RT+EGFR inhibitors (52). Disease-free survival (DFS) and overall survival (OS) were analyzed by the Kaplan-Meier method. Results DNA of HPV16 was found in 12 of 108 tumors (11%) and p16 positivity in 18 tumors (17%), with similar rates in both arms of treatment. After a median follow-up time of 35 months (range 6–135), p16-positive patients treated with RT+EGFR inhibitors showed improved survival compared with those treated with RT+CT (2-year OS 88% vs. 60%, HR 0.18; 95% CI 0.04 to 0.88; p = 0.01; and 2-year DFS 75% vs. 47%, HR 0.17; 95% CI 0.03 to 0.8; p = 0.01). However, no differences were observed in p16-negative patients (2-year OS 56% vs. 53%, HR 0.97; 95% CI 0.55 to 1.7; p = 0.9; and 2-year DFS 43% vs. 45%, HR 0.99; 95% CI 0.57 to 1.7; p = 0.9). Conclusions This is the first study to show that p16-positive patients may benefit more from RT+EGFR inhibitors than conventional RT+CT. These results are hypothesis-generating and should be confirmed in prospective trials.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is an aggressive life-threatening disease associated with high mortality rates. While efforts have been made to explore the molecular mechanisms that contribute to the initiation and progression of HNSCC, most studies focus on protein-coding genes. Understanding of the genomic aberrations associated with noncoding genes (such as microRNAs) and their effects on HNSCC is still relatively limited. Recent evidence suggests that deregulation of microRNA genes (such as downregulation of miR-138) plays an important role in HNSCC. While deregulation of miR-138 has been frequently observed in HNSCC and other cancer types, the precise roles of miR-138 in tumorigenesis remain elusive. Recent bioinformatics analyses and functional studies using in vitro and in vivo systems have identified a number of functional targets for miR-138. These include genes that participate in essential biological processes that are highly relevant to the initiation and progression of HNSCC, including cell migration, epithelial to mesenchymal transition, cell cycle progression, DNA damage response and repair, senescence, and differentiation. However, the biological systems, study design, and data interpretation from these studies are highly variable, which hinder our understanding of the role of miR-138 in tumorigenesis at molecular level. In this review, we will first introduce the significance of microRNA deregulation in HNSCC. We will then provide a comprehensive review and integrative analysis of the existing studies on miR-138, and aim to define its molecular mechanisms that contribute to the initiation and progression of HNSCC.

Abstract
Background Interleukin 6 (IL6) plays an important role in immunoregulation and tumorigenesis in human cancers. Oral squamous cell carcinoma (OSCC) is a malignant tumor of the oral cavity with a male predominant tendency and a poor clinical prognosis. Due to the relatively few cases in females, the gender difference of prognostic markers for OSCC is seldom discussed. Methods In this study, we used immunohistochemical staining methods to investigate the associations between IL6 expression and the clinicopathological characteristics of OSCC. In addition, we collected 74 female and 263 male OSCC patients for evaluation. Results High IL6 expression in tumor cells was significantly associated OSCC patient characteristics including female gender (P<0.001), high lymph node metastatic rate (P = 0.007), and poor tumor differentiation (P = 0.008). Tumor-expressed IL6 had prognostic role in male OSCC patients as defined by the log-rank test (P = 0.014), but not in female patients (P = 0.959). In male OSCC patients, high IL6 expression in tumor cells was associated with poor prognosis (P = 0.025) and a 1.454-fold higher death risk, as determined by Cox regression. Conclusions High IL6 expression in tumor cells was therefore significantly associated with aggressive clinical manifestations and might be an independent survival predictor, particularly in male OSCC patients.

Abstract
BACKGROUND A number of molecular epidemiological studies have been conducted to explore the association of human papillomavirus (HPV) infection with laryngeal cancer. However, the findings are heterogeneous. METHODS We systematically reviewed studies on HPV infection and laryngeal cancer published up to 15 May 2012 and quantitatively summarized the prevalence of HPV infection and its association with the risk of laryngeal cancer by means of meta-analysis. RESULTS In total, 55 eligible studies were included. The overall HPV prevalence in laryngeal cancer tissues was 28.0% (95% confidence interval [CI], 23.5%-32.9%). A total of 26.6% laryngeal cancer patients were infected with high-risk HPV types only, and HPV-16 was most frequently observed type, with a prevalence of 19.8% (95% CI, 15.7%-24.6%). The meta-analysis based on 12 eligible case-control studies suggests a strong association between HPV infection and laryngeal squamous cell carcinoma, with a summary odds ratio (OR) of 5.39 (95% CI, 3.25-8.94). Different magnitudes of association were observed for HPV-16 (OR, 6.07; 95% CI, 3.44-10.70) and HPV-18 (OR = 4.16; 95% CI, .87-20.04; P < .01). Stratified analyses were performed with respect to HPV genotypes and characteristics of the study population. CONCLUSIONS HPV infection, especially infection due to the high-risk type HPV-16, was found to be significantly associated with the risk of laryngeal squamous cell carcinoma.

Abstract
Oral squamous cell carcinoma (OSCC) is the fifth most common type of cancer in the world. The effect of some etiological factors is well established in the literature, such as consumption of tobacco and alcohol. However, approximately 15 to 20% of all oral cancer cases occur in patients without the traditional risk factors, reflecting in numerous cases of OSCC in non-smokers and non-alcoholic drinkers. Also, several studies have suggested a possible association between human papillomavirus and OSCC. Under these aspects, the purpose of this study is to address cases of oral cancer in non-smokers and non-drinkers focusing on the role of HPV, thus contributing to improve the diagnosis and monitoring of OSCC. A computer database search was performed using the Pubmed database. The search key words were: epidemiology, oral squamous cell carcinoma, risk factors and human papillomavirus. It is important to assess patients without the potential risk factors, since this knowledge may help identifying other features associated with the occurrence of oral cancer, enabling an appropriate clinical management and monitoring.

Abstract
The aim of this work is to review the literature on risk factors of oral cavity cancer with a special attention to the definition of the cases, in order to highlight special features of these cancers and of their subsites. PubMed database was systematically searched to access relevant articles published between 1980 and 2010. Reference lists of selected papers were examined to identify further articles. One hundred and two studies met the inclusion criteria. Their results were difficult to compare because of the lack of uniformity in defining oral cavity. In addition, few studies examined risk factors other than alcohol and tobacco, and studies differentiating between subsites were rare. Despite these limitations, some characteristics of oral cavity cancers may be emphasized: smoked tobacco seems to be a stronger risk factor for oral cavity cancer than alcohol, and the floor of the mouth seems to be more sensitive to the harmful effects of alcohol and smoked tobacco. Studies limited strictly to oral cavity cancers and distinguishing between subsites are needed to better understand the aetiology of these cancers, and better define risk groups to target prevention efforts and screening.

Abstract
PURPOSE To study the prognostic value of human papillomavirus (HPV) genotypes in patients with advanced cervical cancer treated with radiation therapy (RT) alone or concurrent chemoradiation therapy (CCRT). METHODS AND MATERIALS Between August 1993 and May 2000, 327 patients with advanced squamous cell carcinoma of the cervix (International Federation of Gynecology and Obstetrics stage III/IVA or stage IIB with positive lymph nodes) were eligible for this study. HPV genotypes were determined using the Easychip® HPV genechip. Outcomes were analyzed using Kaplan-Meier survival analysis and the Cox proportional hazards model. RESULTS We detected 22 HPV genotypes in 323 (98.8%) patients. The leading 4 types were HPV16, 58, 18, and 33. The 5-year overall and disease-specific survival estimates for the entire cohort were 41.9% and 51.4%, respectively. CCRT improved the 5-year disease-specific survival by an absolute 9.8%, but this was not statistically significant (P=.089). There was a significant improvement in disease-specific survival in the CCRT group for HPV18-positive (60.9% vs 30.4%, P=.019) and HPV58-positive (69.3% vs 48.9%, P=.026) patients compared with the RT alone group. In contrast, the differences in survival with CCRT compared with RT alone in the HPV16-positive and HPV-33 positive subgroups were not statistically significant (P=.86 and P=.53, respectively). An improved disease-specific survival was observed for CCRT treated patients infected with both HPV16 and HPV18, but these differenced also were not statistically significant. CONCLUSIONS The HPV genotype may be a useful predictive factor for the effect of CCRT in patients with advanced squamous cell carcinoma of the cervix. Verifying these results in prospective trials could have an impact on tailoring future treatment based on HPV genotype.

Abstract
Human Papillomavirus (HPV) related oropharyngeal squamous cell carcinomas (OPSCCs) are reported to have improved prognosis and survival in comparison to other head and neck squamous cell cancers (HNSCCs). This systematic review and meta-analysis examines survival differences in HPV-positive HNSCC and OPSCC subtypes including tonsillar carcinoma in studies not previously investigated. Four electronic databases were searched from their inception till April 2011. A random effects meta-analysis was used to pool study estimates evaluating disease-specific (death from HNSCC), overall (all-cause mortality), progression-free and disease-free (recurrence free) survival outcomes in HPV-positive vs. HPV-negative HNSCCs. All statistical tests were two-sided. Forty-two studies were included. Patients with HPV-positive HNSCC had a 54% better overall survival compared to HPV-negative patients HR 0.46 (95% CI 0.37-0.57); the pooled HR for tonsillar cancer and OPSCC was 0.50 (95% CI 0.33-0.77) and HR 0.47 (95% CI 0.35-0.62) respectively. The pooled HR for disease specific survival was 0.28 (95% CI 0.19-0.40); similar effect sizes were found irrespective of the adjustment for confounders, HPV detection methods or study location. Both progression-free survival and disease-free survival were significantly improved in HPV-positive HNSCCs. HPV-positive HNSCCs and OPSCCs patients have a significantly lower disease specific mortality and are less likely to experience progression or recurrence of their cancer than HPV-negative patients; findings which have connotations for treatment selection in these patients.

Abstract
Perhaps one of the most important developments in head and neck oncology of the past decade is the demonstration that patients with human papillomavirus (HPV)-mediated oropharyngeal cancers have significantly improved outcomes, compared to HPV-negative counterpart patients. This has become the basis for clinical trials investigating the impact on "treatment deintensification" for patients with HPV-mediated oropharyngeal cancers. Unfortunately, the significance of HPV in non-oropharyngeal head and neck cancers is much less certain. Our goal is to systematically review the published data regarding the role HPV in carcinomas of the oral cavity, larynx, sinonasal tract and nasopharynx with respect to HPV detection frequency, viral activity, and association with outcome. We also present preliminary data on HPV16/18 transcriptional status in oral cavity carcinomas, as well as salivary gland neoplasia, as determined by nested reverse transcription PCR for HPV E6/E7 RNA. The weighted prevalence (WP) of HPV DNA detection in 4,195 oral cavity cancer patients is 20.2 %, (95 % CI 16.0 %, 25.2 %). HPV16 is the most common type detected. Importantly, no data currently demonstrates a significant association between the presence of HPV DNA and improved outcome. The WP of HPV DNA in 1,712 laryngeal cancer patients is 23.6 %, (95 % CI 18.7 %, 29.3 %). Similarly, no association has yet been demonstrated between HPV DNA status and outcome. The WP of HPV DNA detection in 120 sinonasal cancer patients is 29.6 % (95 % CI 17.8 %, 44.9 %), and in 154 nasopharyngeal carcinoma patients is 31.1 %, (95 % CI 20.3 %, 44.5 %). Recent preliminary data also suggests an association between HPV and certain salivary gland neoplasms. The clinical significance of these findings is unclear. The published data strongly support the need for studies on patients with oral and laryngeal carcinomas that will be powered to find any differences in clinical outcome with respect to HR-HPV and p16 overexpression.

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
OBJECTIVES Infection with human papillomavirus (HPV) is linked to oropharyngeal cancer. This analysis investigated possible associations between HPV status, smoking history and survival outcome in patients with neck metastasis and carcinoma of unknown primary (CUP). MATERIALS AND METHODS Registries at the Universities of Hamburg and Kiel were searched for patients with CUP diagnosed from 2002 to 2011 who had formalin-fixed and paraffin-embedded metastatic lymph node samples available. All patients underwent routine diagnostic procedures to establish the primary site and received radiotherapy (60Gy using conventional fractionation) with or without concurrent cisplatin-based chemotherapy depending on disease extent. Genotyping was performed using polymerase chain reaction; p16([INK4a]) expression was assessed using immunohistochemistry. RESULTS Sixty-three patients were included; 23 (37%) had HPV DNA/p16+ samples and 40 (63%) were negative for either/both markers. A high proportion of patients had a history of tobacco smoking; significantly fewer patients with HPV+/p16+ samples were smokers than those who were negative for either/both markers (61% vs. 90%, respectively; p = 0.0067). There were no statistically significant differences between overall or recurrence-free survival in HPV+/p16+ patients vs. those negative for either/both markers. Overall survival appeared to be superior in patients with <10 pack-years smoking history and HPV+/p16+ disease. CONCLUSIONS This study, the largest to date investigating HPV status in head and neck CUP, identified HPV and p16 overexpression in over one-third of patients. Tobacco smoking history appeared to affect survival in HPV+/p16+ patients. Smoking status should be considered as a prognostic factor in patients with CUP, along with HPV DNA status.

Abstract
Background Previous studies indicated that oral squamous cell carcinomas (OSCC) might be related to human papilloma virus (HPV) infection. However, up to now, there still lacks a large sample study to analyze the relationship between OSCC in a Chinese population and oral HPV infection. In the present study, we used a meta-analysis to evaluate the relationship of OSCC with HPV infection in a Chinese population. Methods The reports on HPV and OSCC in a Chinese population published between January, 1994, and September, 2011 were retrieved via CNKI/WANFANG/OVID/MEDLINE databases. According to the inclusion criteria, we selected 18 eligible case-control studies. After testing the heterogeneity of the studies by the Cochran Q test, the meta-analyses for HPV and HPV16 were performed using the fixed effects model. Results The overall positive rates of HPV and HPV16 in OSCC were 58.0% (354/610; 95% confidence interval [CI], 54.1–61.9) and 47.47% (169/356; 95% CI: 42.3–52.7), respectively; which were significantly higher than those in normal controls 10.44% (26/249; 95% CI: 7.2–14.7) and 7.1% (13/182; 95% CI: 4.2–11.8). Quantitative meta-analysis revealed that, compared with normal controls, the combined odds ratios of OSCC with HPV or HPV16 infection were 12.7 (95% CI: 8.0–20.0) and 9.0 (95% CI: 5.1–15.6), respectively. Both Begg's test and funnel plots revealed that no publication bias was found in this present study (P>0.05). Conclusions High incidences of HPV infection (mainly involving HPV16) were found in the samples of Chinese OSCC. For the Chinese population, HPV infection elevates the risk of OSCC tumorigenesis. Prophylactic HPV-vaccination may reduce the burden of HPV-related OSCC in China.

Abstract
OBJECTIVES/HYPOTHESIS The prevalence of human papillomavirus (HPV) in a clinical series of 162 patients with oral squamous cell carcinoma (OSCC) was studied. Furthermore, we analyzed the correlation between the immunohistochemical expression of p16, p53, epidermal growth factor receptor (EGFR), and HPV status to predict survival in OSCC patients. STUDY DESIGN Retrospective study. METHODS Paraffin-embedded samples from OSCC patients (n = 162) were evaluated for the presence of HPV DNA using both GP5+/GP6+ consensus polymerase chain reaction (PCR) and type-specific E6/E7 PCR to detect HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 67, and 68. Immunohistochemical staining for p16, p53, and EGFR was also performed. RESULTS The type-specific E6/E7 PCR demonstrated that 65 of the 147 OSCC patients (44%) presented with high-risk (hr) HPV types and that 38 of the 147 OSCC patients (26%) presented with low-risk (lr) HPV types. Comparable p53 and EGFR expression levels were observed in the hr HPV+ group (41.5% p53+, 92% EGFR+) and the lr HPV+ group (57% p53+, 92% EGFR+). Conversely, a slight increase in the proportion of p16+ tumors was observed in the hr HPV+ group (65%) compared with the lr HPV+ group (44%). In regard to patient outcome, the presence of HPV was correlated with a worse prognosis (P = .007). CONCLUSIONS A high prevalence of hr and lr HPV infections was detected in the OSCC patients included in the study. Moreover, hr HPV positivity was correlated with a decreased 5-year disease-free survival rate compared with HPV- and lr HPV+.

Biopsy vs. brushing: comparison of two sampling methods for the detection of HPV-DNA in squamous cell carcinoma of the oral cavity. Oral Oncol 2012; 48:870-5. [PMID: 22498489 DOI: 10.1016/j.oraloncology.2012.03.002] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2011] [Revised: 03/02/2012] [Accepted: 03/02/2012] [Indexed: 11/16/2022]
Abstract
BACKGROUND HR HPV infection was proposed as aetiological factor of oral squamous cell carcinomas (OSCC). HPV frequency in OSCC is highly variable, due to the discrepancy in oral sampling procedures, HPV testing methods and inclusion criteria regarding tumour site (strictly oral cavity vs. nearby structures). Our aim was to compare HPV DNA frequency and type-specific distribution in paired cytological and histological samples of SCC strictly located in oral cavity. The correlation between HPV detection rate by each method of sampling and demographical, behavioural and clinical-pathological variables was also examined. PATIENTS AND METHODS HPV DNA was detected in brushed cells and formalin-fixed paraffin-embedded biopsies obtained from 83 consecutive unselected immunocompetent adults with OSCC. HPV DNA detection was performed in all samples by nPCR followed by direct DNA sequencing and the assay INNO-LiPA HPV Genotyping. Univariate and multivariate statistics were used, including Cohen κ index to evaluate agreement between two methods and association between HPV infection and demographical, behavioural and clinical-pathological variables for each method of sampling (p<0.05 statistically significant). RESULTS HPV DNA was detected in 15.7% (13/83) of brushings and 12.1% (10/83) of biopsies (p>0.05). High risk HPV 51, 16 and 39 were genotypes more frequently detected, especially among biopsies; no concordance between two methods was found (Cohen κ index=0.04, p=0.34). CONCLUSION A fraction of OSCC could be linked to HR HPV infection in the Mediterranean area. Although without a statistical significance, biopsy specimen demonstrated more accurate for HR HPV detection than brushing in OSCC.

HPV DNA, E6*I-mRNA expression and p16INK4A immunohistochemistry in head and neck cancer - how valid is p16INK4A as surrogate marker? Cancer Lett 2012; 323:88-96. [PMID: 22484467 DOI: 10.1016/j.canlet.2012.03.033] [Citation(s) in RCA: 70] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2012] [Revised: 03/05/2012] [Accepted: 03/29/2012] [Indexed: 12/16/2022]
Abstract
It has been proposed that p16(INK4A) qualifies as a surrogate marker for viral oncogene activity in head and neck cancer (HNSCC). By analyzing 78 HNSCC we sought to validate the accuracy of p16(INK4A) as a reliable marker of active HPV infections in HNSCC. To this end we determined HPV DNA (HPVD) and E6*I mRNA (HPVR) expression status and correlated these results with p16(INK4A) staining. In tonsillar SCC 12/20 were HPVD+ and 12/12 of these showed active HPV infections whereas in non-tonsillar SCC 10/58 were HPVD+ and 5/10 showed active HPV infections. Thus, we prove about 8% of non-tonsillar SCC to be also correlated with HPV-associated carcinogenesis. Strikingly, 3/14 (21.4%) of tonsillar and non-tonsillar HPVD+/HPVR+ cases did not show p16(INK4A) overexpression and these cases would have been missed when applying initial p16(INK4A) staining only. However, in 13 cases negative for HPV, DNA p16(INK4A) was overexpressed. In conclusion, our data confirm tonsillar SCC to be predominantly but not only associated with active HPV infections. Furthermore, our data show that p16(INK4A) overexpression is not evident in a subgroup of HNSCC with active HPV infection. Definitive HPV data should therefore be utilized in diagnostics and treatment modalities of HPV positive and HPV negative HNSCC patients, resulting in a paradigm shift regarding these obviously different tumor entities.
