Abstract
To assess the exact role of high-risk HPV testing in patients of carcinoma unknown primary with secondary metastasis to the neck who underwent TORS and neck dissection for identification of the primary site. A prospective study was carried out at a tertiary care centre over one year. Patients with unilateral neck swelling, which was cytologically proven squamous cell carcinoma neck metastasis, were included in the study. After clinicopathological evaluation, they underwent TORS-assisted ipsilateral radical tonsillectomy, tongue base mucosal wedge biopsy for primary site identification, and ipsilateral neck dissection. They underwent HPV RNA ISH from the tonsil, the base of the tongue and blood. They also underwent HPV DNA testing from the blood. P16 was done in the base of tongue, tonsil, and lymph node specimens. In the study cohort of 18 patients who underwent ipsilateral radical tonsillectomy, mucosal tongue base wedge biopsy and neck dissection, p16 positivity was isolated in 5.56%, 0% and 2.78% of patients, respectively. (n = 1/18, 0/18, 5/18). Interestingly, HPV E7 mRNA expression was absent in the tonsil /base of tongue specimens, but metastatic lymph nodes displayed expression in 11.11%. HPV DNA was undetected in all analysed tissues and patients' blood. In the Indian subcontinent, it is not essential to do detailed high-risk HPV analysis in cases of carcinoma unknown primary with secondary metastasis to the neck.

Abstract
BACKGROUND Human papillomavirus (HPV) is increasingly recognized as a significant risk factor in the development of head and neck cancers (HNCs), with varying prevalence and impact. This study aims to systematically review and analyze the prevalence of HPV in HNCs in India, providing insights into regional variations. METHODS A comprehensive literature search was carried out using PubMed, Embase, and Web of Science up to November 10, 2023. Inclusion criteria focused on original research reporting HPV-positive cases among HNC patients in India. We used Nested-Knowledge software, for screening, and data extraction. The modified Newcastle-Ottawa Scale was used for quality assessment of included studies. We pooled the prevalence of HPV among HNC patients and performed a random-effects model meta-analysis using R software (version 4.3). RESULTS The search yielded 33 studies, encompassing 4654 HNC patients. The pooled prevalence of HPV infection was found to be 33% (95% CI: 25.8-42.6), with notable heterogeneity (I² = 95%). Analysis of subgroups according to geographical location indicated varying prevalence rates. Specifically, the prevalence was 47% (95% CI: 32.2-62.4) in the eastern regions and 19.8% (95% CI: 10.8-33.4) in the western regions. No evidence of publication bias was detected. CONCLUSION The observed considerable regional disparities on the prevalence of HPV in HNC patients in India emphasizes the need for integrated HPV vaccination and screening programs in public health strategies. The findings underline the necessity for further research to explore regional variations and treatment responses in HPV-associated HNCs, considering the impact of factors such as tobacco use and the potential benefits of HPV vaccination.

Abstract
PURPOSE Head and neck cancer accounts for about one third of the global burden in India. Mucosal high-risk human papillomavirus (HPV) has been hypothesized as a contributory risk factor for head and neck cancer (HNC) but its prevalence in Indian patients is not well established. Therefore, this systematic review and meta-analysis aimed to estimate the prevalence of HPV in HNC in India and their attributable fraction by considering the biomarkers of carcinogenesis, p16, and HPV E6/E7 mRNA. METHODS A systematic literature search was done in Medline via PubMed, Embase, Scopus, ScienceDirect, ProQuest, and Cochrane to identify studies on HPV and HNC in the Indian population, published between January 1990 and October 2022. Fifty-four eligible studies were identified and relevant clinical information was collected. Meta-analysis was conducted to estimate the pooled prevalence of HPV DNA, p16INK4a, and E6/E7 mRNA percent positivity by random-effect logistic regression model using Metapreg, STATA 18. RESULTS Thirty-four high-quality studies were taken for meta-analysis. The pooled prevalence of HPV in HNC was 20% (95% CI, 12 to 32) with a high level of heterogeneity (I2 = 90.79%). The proportion of HPV in oropharyngeal cancer (OPC; 22% [95% CI, 13 to 34]) and laryngeal cancer (LC; 29% [95% CI, 17 to 46]) was higher than in oral cancer (OC; 16% [95% CI, 8 to 30]). The HPV-attributable fraction of OPC, considering the E6/E7 mRNA and p16 positivity, was 12.54% and 9.68%, respectively, almost similar to LC (11.6% and 9.57%), while it was much lower in OC (3.36% and 4%). CONCLUSION The HPV-attributable fraction is considerably lower for OC, suggesting a negligible causative role of HPV in OC. A significant proportion of OPC and LC are attributed to HPV; however, their exact causative role is unclear because of the presence of other known risk factors.

Abstract
The high incidence of oral carcinomas is due to its multifactorial etiology and the presence of various risk factors. Human Papillomavirus (HPV) has a proven role in the pathogenesis of oral carcinomas, but in the recent times there has been an increasing incidence of oral cancers who are negative for HPV infection. Also, these patients are non-smokers and non-drinkers so it could be speculated that these oral cancers are due to some other etiological factor probably of other viral infections. Therefore, this study examined the prevalence of Epstein Barr Virus (EBV) and Herpes Simplex Virus (HSV) among oral cancer patients. This cross-sectional study was conducted from January 2019 to June 2020. Biopsy samples from 47 newly diagnosed untreated patients with oral malignancies were collected along with their demographic and clinicopathological information. DNA extracted from the biopsies was processed for nested PCR for the detection of EBV and HSV. All the samples tested negative for HPV and HSV infection. Nested PCR detected 29 cases (70.7%) to be positive for EBV. The non-cancerous adjacent tissues also were negative for HPV, EBV and HSV. The prevalence of EBV was found to be more in males (62.1%) and the highest number of cases was of the left buccal mucosa compromising 34% of the total cases. From the present study it can be concluded that EBV but not HSV infection is associated with an increased risk of developing oral cancers. Although, 70.7% of the patients were found to be positive for EBV whether the viral infection played any role in the driving the malignancy needs to be further elucidated.

Abstract
OBJECTIVE This study aimed to explore the characteristics of human papillomavirus (HPV) in oropharyngeal carcinoma (OPC), in order to provide a new theoretical basis for the prevention, treatment, and management of OPC. METHODS The electronic databases were searched available publications relevant to HPV infection and OPC. Studies were collected until July, 2023. The effect sizes were combined using R 4.2.2 software. Subgroup and sensitivity analyses were performed to explore the sources of heterogeneity. Funnel plot and Egger's test were used to assess the publication bias. RESULTS Seventy-one studies were included with 10,908 OPC patients. The pooled prevalence of HPV and HR-HPV infection was 44.22% and 43.94%, respectively. The genotypes of HR-HPV were HPV16 (37.24%), HPV33 (2.44%), HPV18 (1.64%), HPV35 (1.53%), and HPV58 (0.89%). The highest HPV infection was in North America (66.87%), Oceania (43.09%), and Europe (41.49%), lowest in Africa (4.89%). Females exhibited higher HPV infection (43.18% vs 34.59% in males). Top subsites of HPV infection was tonsil (45.78%), followed by base of tongue (36.66%). Infection was higher in OPC patients aged > 60 (38.15%) than < 60 (34.73%). The prevalence of HPV infection in stage I-II of OPC patients is higher than that in stage III-IV. CONCLUSIONS HPV genotyping (16, 18, 33, 35, 58) is a key factor in the prevention and treatment of OPC. Identifying tonsils, base of tongue, and soft palate as common subsites to improve early detection. Elderly women with high HPV infection require attention to risk management and health education for prevention.

Abstract
This systematic review and meta-analysis aims to evaluate the scientific evidence on the implications of retinoblastoma protein (pRb) alterations in oral cancer, in order to determine its prognostic and clinicopathological significance. PubMed, Embase, Web of Science, and Scopus were searched for studies published before February 2022, with no restrictions by publication date or language. The quality of the studies using the Quality in Prognosis Studies tool (QUIPS tool). Meta-analysis was conducted to achieve the proposed objectives, as well as heterogeneity, subgroup, meta-regression, and small study-effects analyses. Twenty studies that met the inclusion criteria (2451 patients) were systematically reviewed and meta-analyzed. Our results were significant for the association between the loss of pRb expression and a better overall survival (HR = 0.79, 95%CI = 0.64-0.98, p = 0.03), whereas no significant results were found for disease-free survival or clinico-pathological parameters (T/N status, clinical stage, histological grade). In conclusion, our evidence-based results demonstrate that loss of pRb function is a factor associated with improved survival in patients with OSCC. Research lines that should be developed in the future are highlighted.

Abstract
The recent increase in high-risk human papillomavirus (HR-HPV)-associated oral and oropharyngeal cancers has gained considerable importance due to their distinct clinical and molecular characteristics. However, the natural history of oral HPV from acquisition to persistence and malignant transformation is still unclear. The global prevalence of oral HPV infection in healthy individuals ranges from 0.67% to 35%, while 31%-38.5% in head and neck cancer (HNC). The persistence rate of oral HR-HPV infection is 5.5% -12.8% globally. India has the highest HNC burden due to apparent differences in predisposing factors compared with the West. The prevalence of oral HPV in healthy individuals and its contribution to HNC is less evident in Indian studies. HR-HPV-associated HNC in this region accounts for 26%, with an active infection in 8%-15% of these tumors. There is a lack of concordance in the expression of p16 as a surrogate marker for HPV detection in HNC because of differences in behavioral risk factors. Due to a lack of evidence, treatment de-escalation cannot be implemented despite the improved outcome of HPV-associated oropharyngeal cancers. This review critically analyzes the existing literature on the dynamics of oral HPV infection and HPV-associated HNC, identifying potential avenues for future research. A better understanding of the oncogenic role of HR-HPV in HNC will help to formulate novel therapeutic approaches and is expected to have a significant public health impact as preventive strategies can be implemented.

Abstract
Purpose . The transoral robotic surgery is a newer modality being used in surgical treatment of early oropharyngeal cancer. The aim of this study is to assess the outcome of these cases in terms of two year disease free survival and overall survival. Methods Between July 2016 and September 2018, 58 patients suffering from early oropharyngeal cancer underwent transoral robotic surgery with neck dissection at a tertiary referral centre. 43 of them have completed two years follow up and were analyzed for disease free survival and overall survival. 41 patients had HPV analysis done . Results The surgical margins were positive in 9/43 patients ( 6 in upfront surgery and 3 in the salvage cohort). Adjuvant therapy was administered to 16/34 patients on account of either positive margins or multiple nodal metastasis. 88% patients were found to be HPV negative. The two year disease free survival for the upfront cohort was 88.2% and salvage cohort was 55.5%. The overall survival was 86.05%. Conclusions The study highlights good locoregional control and two year disease free survival in HPV negative oropharyngeal cancer undergoing robotic surgery. Additionally, a positive surgical margin and recurrence were the statistically significant variables influencing 2 year disease free survival. Trans oral robotic surgery is an excellent tool for early tumors of the oropharynx. The presence of a positive surgical margin is a grim sign for survival and has a significant impact on positive outcome.

Abstract
Simple Summary Among the over 200 human papillomavirus (HPV) genotypes identified, approximately 15 of them can cause human cancers. In this review, we provided an updated overview of the distribution of cancer-causing HPV genotypes by countries in East, Southeast and South Asia. Besides the standard screening and treatment methods employed in these regions, we unravel HPV detection methods and therapeutics utilised in certain countries that differ from other part of the world. The discrepancies may be partly due to health infrastructure, socio-economy and cultural diversities. Additionally, we highlighted the area lack of study, particularly on the oncogenicity of HPV genotype variants of high prevalence in these regions. Abstract Human papillomavirus (HPV) infection remains one of the most prominent cancer-causing DNA viruses, contributing to approximately 5% of human cancers. While association between HPV and cervical cancers has been well-established, evidence on the attribution of head and neck cancers (HNC) to HPV have been increasing in recent years. Among the cancer-causing HPV genotypes, HPV16 and 18 remain the major contributors to cancers across the globe. Nonetheless, the distribution of HPV genotypes in ethnically, geographically, and socio-economically diverse East, Southeast, and South Asia may differ from other parts of the world. In this review, we garner and provide updated insight into various aspects of HPV reported in recent years (2015–2021) in these regions. We included: (i) the HPV genotypes detected in normal cancers of the uterine cervix and head and neck, as well as the distribution of the HPV genotypes by geography and age groups; (ii) the laboratory diagnostic methods and treatment regimens used within these regions; and (iii) the oncogenic properties of HPV prototypes and their variants contributing to carcinogenesis. More importantly, we also unveil the similarities and discrepancies between these aspects, the areas lacking study, and the challenges faced in HPV studies.

Head Neck 2021; 43:2896-2906. [PMID: 34050557 DOI: 10.1002/hed.26771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 04/19/2021] [Accepted: 05/20/2021] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND With the termination of RTOG 1221, there remains a lacuna regarding the optimal treatment for human papillomavirus (HPV)-negative oropharyngeal squamous cell carcinoma (OPSCC). METHODS Matched pair analysis with propensity score matching (PSM) between Arm I (transoral surgery [TOS] + risk-stratified adjuvant treatment) and Arm II (nonsurgical treatment - radiation/chemoradiation) in HPV(-) OPSCC. RESULTS Unmatched comparison of Arm I (n = 57) and Arm II (n = 89) indicated significantly better overall survival (OS) and disease-free survival (DFS) for Arm I. PSM by matched pairs (n = 48, 24 each arm) indicated 5-year OS at 80% and 72.1%, respectively, for Arm I and II (p > 0.05) and corresponding DFS at 65.3% and 33.4% (p > 0.05). Subgroup analysis did not demonstrate statistical difference in outcomes in stage II and III, but stage IV tumors had significantly better outcomes in Arm I than Arm II (4-year OS: 100% vs. 21%, p = 0.04; DFS: 75% vs. 14.3%, p = 0.04). CONCLUSIONS TOS +/- adjuvant was found to have oncological outcomes at par with nonsurgical modalities in stage I-III OPSCC, whereas a distinct survival advantage was noted in case of stage IV tumors.

Prevalence of Human Papillomavirus (HPV) DNA among Men with Oropharyngeal and Anogenital Cancers: A Systematic Review and Meta-Analysis. Asian Pac J Cancer Prev 2021; 22:1351-1364. [PMID: 34048162 PMCID: PMC8408381 DOI: 10.31557/apjcp.2021.22.5.1351] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 05/10/2021] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVE The term ''Human Papillomavirus'' or ''HPV'' has become synonymous with uterine cervical cancer leading to feminisation of all the preventive measures, especially immunisation. Taking into consideration the rising number of HPV associated cancers among men in many developed countries and the risk of transmission to women, male HPV infection is a serious concern. A systematic review and meta-analysis of literature was performed to determine the global prevalence of HPV among men with oropharyngeal and anogenital cancers. METHODS A systematic review and meta-analysis of literature was performed searching electronic databases for published articles in English between January 1984- April 2020 based on standard systematic review guidelines. The meta-analysis component was modified appropriately for the synthesis of prevalence study results. National Institutes of Health checklist for observational, cohort and cross-sectional studies was used to assess the quality of the studies selected after the abstract and content review. The meta-analysis was performed in STATA version 13.0 (College Station, Texas 77,845 USA) and the forest plots were constructed using metan package in STATA. RESULTS Through the electronic search of databases, 3486 original articles were screened for eligibility. Fifty-eight articles were systematically reviewed and 42 articles were qualified for meta-analysis including 4,250 men with oropharyngeal, penile and prostate cancers. The pooled prevalence of HPV DNA in oropharyngeal cancers was 45% (95%CI 24.0%-66.0%). Meanwhile the pooled prevalence rates of 48% (CI 40.0%- 57.0%) and 19% (CI 10.0%-29.0%) were observed in penile and prostate cancers respectively. Even though, articles regarding HPV prevalence in anal cancers were systematically reviewed, none of the studies were qualified for meta-analysis. CONCLUSION Higher pooled prevalence of HPV DNA was observed among men with oropharyngeal and penile cancers. Multicentric molecular studies investigating the prevalence of HPV in prostate cancers have to be planned in future.

Abstract
OBJECTIVE To assess the oncological outcome and prognostic factors for primary Oral Squamous Cell Cancer (OSCC) staged as per AJCC 8th pTNM, and treated by the contemporary standard of primary surgery and pathology directed adjuvant radiation-chemoradiation. METHODS A single institution cohort from a tertiary care academic institution in North India. Case inclusion 2013 to 2016; n = 218, median follow-up 35 months. All patients were restaged as per the AJCC 8th pTNM classification. Analysis for Overall Survival (OS), Disease-free Survival(DFS), and factors impacting outcome (Cox proportionate model Multivariate analysis). RESULTS AJCC pTNM 7th to 8th edition conversion led to upstaging in 16.5%. Stage-II demonstrated greatest stage migration and apparent improvement in OS and DFS (P < .09). Discordance was noted between the presurgical (clinico-radiologic) and postsurgical (pathological) nodal status in 40.3% (88/218; 54 pathologically upstaged;34 downstaged). Pathological downstaging was particularly significant with advanced stage Gingivo-Buccal Cancers (25/73-34.7%). Stage-I-II early cancers had 3 years. OS-86.7% and DFS-78.8%; Stage-III-IV advanced cancers had 3 years. OS-56.7% and DFS-46.6%. Multivariate analysis identified poorer OS and DFS for age < 40 years (HR-1.8; 2.0), skin involvement (HR-2.1; 2.6) and pN+ status (HR-2.4; 3.5). Bone involvement did not compromise survival in this surgically treated set of patients. CONCLUSION Age < 45 is newly identified as significantly compromising DFS and OS in Oral Cancer. Established factors of skin involvement and pN+ are confirmed as impacting DFS-OS. An apparent improvement in survival in Stage II Cancers is noted as consequent to adoption of AJCC 8th edition staging.

Abstract
OBJECTIVE Head and neck squamous cell carcinoma (HNSCC) pose a great danger to society and now we have shreds of evidence for Human Papillomavirus (HPV) being one of the major causative agents for it. Though the prevalence of HPV varies throughout the world, it is gradually on the rise. The present systematic review aims to retrospect all the available studies on the prevalence of HPV in HNSCC in India and its clinicopathological aspect to study how it is different from HPV negative HNSCC. METHODS An objective electronic database search was conducted in PUBMED Central, MeSH, NLM Catalog, Bookshelf, and PUBMED published in 25 years period from 1994 till 2019. A total of 33 articles were shortlisted for the present review. RESULTS Studies conducted across India show the prevalence of HPV in Head and Neck Cancers ranging from 0-86.6%. Some studies reported that HPV positive HNSCC is more common in younger age, presents with advanced stage disease, and more commonly presents with nodal metastasis. As opposed to western literature HPV positive HNSCC in India is associated with a well-differentiated tumor grade. There is no difference in treatment outcome and survival among HPV positive and negative HNSCC. CONCLUSION Exact prevalence of HPV in HNSCC is still doubtful but now we have some insight into it. The prevalence of HPV in Indian HNSCC patients has risen gradually but treatment outcome and survival may be poorer compared to other countries. However definite conclusions cannot be drawn without proper prospective study.

Are Histomorphological Features Predictive of p16 Immunopositivity Different for Oral and Oropharyngeal Squamous Cell Carcinoma? Indian J Surg Oncol 2020; 11:248-255. [PMID: 32523271 DOI: 10.1007/s13193-020-01058-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2019] [Accepted: 03/17/2020] [Indexed: 10/24/2022] Open
Abstract
Evidence from current studies show that squamous cell carcinomas at oral and oropharyngeal sites are distinct and unique, with their own separate etiopathogenesis, treatment, and prognosis. The aim of this work is to correlate p16 immunohistochemical expression with histomorphological features suggestive of HPV infection in oral and oropharyngeal squamous cell carcinoma. A total of 50 consecutive biopsy cases of oral squamous cell carcinoma (OSCC) and 50 consecutive biopsy cases of oropharyngeal squamous cell carcinoma (OPSCC) were evaluated for features suggestive of HPV infection like focal basaloid appearance, nests, and lobules of tumor cells with pushing borders, absence of stromal reaction, central necrosis, focal lymphoepithelial morphology, presence of koilocytes, and non-keratinizing or hybrid morphology. Immunostaining was performed using p16 monoclonal antibody (clone mouse 16P04). Only cases showing a moderate (2+) to high intensity (3+) staining in more than 75% cells were taken as p16 immunopositive. The histological features were correlated with p16 immunopositivity. A total of 18/50 (36%) cases of oral squamous cell carcinoma and 27/50 (54%) cases of oropharyngeal squamous cell carcinoma were p16 immunopositive. On statistical analysis, only nests/lobules with pushing borders were found to have a significant correlation with p16 immunopositivity (P value = 0.0012) for OSCC cases. For OPSCC cases, four histological features namely nests and lobules with pushing borders (P value = 0.0001), focal basaloid appearance (P value = 0.0041), lymphoepithelial morphology (P value = 0.0029), and non-keratinizing/hybrid morphology (P value = 0.0141) had a significant correlation with p16 immunopositivity. Histomorphological features are more helpful in predicting p16 immunopositivity in OPSCC than OSCC.

Abstract
There has been a surge in human papillomavirus (HPV)-positive oropharyngeal cancers (OPCs) in the West. Although the prognosis of HPV-positive OPC is good, de-escalation strategies have so far not been able to confirm comparable cancer control. We examine the strategies implemented across the globe to safely reduce toxicities in HPV-positive disease. HPV-negative OPC has a poorer prognosis and is more prevalent in Eastern countries. We outline the intensification strategies currently used in HPV-negative cancers, with an aim to better prognosis. With recent improvements in clinical trial frameworks in Eastern countries such as India, we discuss areas where joint collaborative research between Western and Eastern countries could further improve outcomes in OPC.

Abstract
Background: Head and Neck Squamous Cell Carcinomas (HNSCC) is the sixth most common cancer globally. In India, on an average 25-30% of all cancer cases affect the head and neck. The etiological factors associated with HNSCC are tobacco, alcohol and environmental carcinogens. However there are few cases, where there are no obvious risk factors involved. In western counties, there are many reports of human papilloma virus (HPV) association with HNSCC. Hence, we conducted a study to determine the role of HPV infection and risk factors among patients with HNSCC. Materials and Methods: A prospective, cross-sectional study was conducted in a tertiary referral centre from January 2014 to March 2016. 88 patients were enrolled in the study. Socio- demographic, behavioural data, site and subsite involvement, histopathology, staging and treatment were documented. Polymerase chain reaction (PCR) was performed to detect the presence of HPV DNA using consensus primers MY 09/11 and GP5+/GP6+ and further the samples were subjected to PCR for detecting HPV type 16 and 18. Results: The study included 88 participants with HNSCC. 57 had oral and oropharyngeal squamous cell carcinoma, 11 with laryngeal malignancy and 20 involving hypopharynx. Among the participants buccal mucosa (n=22) was the most common subsite involved, majority (50%) had moderately differentiated squamous cell carcinoma and 53.4% presented in stage IV. 2 (2.6%) cases were positive for HPV consensus and both were positive for HPV 16, one case each in larynx and hypopharynx. There was statistical significance in the association between betel nut chewing, cigarette smoking and alcohol intake as risk factors in the carcinogenesis of HNSCC. Conclusion: In our setting in South India, HPV does not play a major role in the carcinogenesis of HNSCC but betel nut chewing, tobacco exposure and alcohol consumption remain major risk factors for HNSCC.

Abstract
INTRODUCTION Epigenetic modifications have been reported to play an important role in regulating gene expression and these modifications become critical when they have a role in controlling another important layer of epigenetic regulation namely microRNAs. In the present study, we have identified the microRNAs that may be regulated by promoter DNA methylation and histone acetylation in Human papilloma virus-positive head and neck squamous cell carcinoma. METHODOLOGY HPV-negative cell line (UPCI:SCC-116) and HPV-16 +ve cell line (UPCI:SCC-090) were treated with methylation inhibitor (5-aza-2'-deoxycytidine, AZA) and acetylation inhibitor (Trichostatin-A, TSA), followed by micro-array analysis. The differentially expressed miRNAs were validated in control (n = 10), HPV-16 +ve (n = 30), and HPV -ve (n = 30) HNC, TCGA (n = 529) tissue samples, and two HPV -ve (SCC116 and Hacat) and two HPV +ve (SCC090 and SiHa) cell lines. Methylation-specific PCR (MSP) and chromatin immunoprecipitation assay (CHIP) were performed to validate their regulation. In silico and in vitro analyses of identified miRNAs were done to study putative pathways they target and their possible role in carcinogenesis. RESULTS Among 10 miRNAs specifically up-regulated in microarray analysis of AZA-treated SCC090 cells, we observed significantly decreased expression of hsa-miR-181c-5p, hsa-miR-132-5p, hsa-miR-658 in HPV +ve HNC cohort, TCGA tissue samples, and cell lines as compared to their HPV -ve counterpart, and their promoter region also possesses CpG islands. MSP and analysis of TCGA data (MethHC) revealed increased frequency of methylation at the promoter of hsa-miR-132-5p that is negatively correlated with its expression. In TSA-treated SCC090 cells, out of 7 miRNAs, two namely Hsa-miR-129-2-3p and Hsa-miR-449a were found to be up-regulated as compared to HPV -ve cells. However, the levels of enrichment by anti-acetyl-H3 and anti-acetyl-H4 were significantly low in cell lines compared to respective controls and both were up-regulated in HPV +ve compared to HPV -ve TCGA tissue samples. In silico analysis revealed hsa-miR-132-5p targeted canonical β-catenin/wnt pathway and modulation of down-stream genes of the pathway was observed on over-expression/inhibition of hsa-miR-132-5p. CONCLUSION This study suggests the role of epigenetic modifications in regulating expression of miRNAs in HPV +ve HNSCC.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide with high recurrence, metastasis, and poor treatment outcome. Recent studies have reported that non-coding RNA (ncRNA) might play critical role in regulating different types of cancer. MicroRNAs (miRs) are short ncRNAs (20-25 nucleotides) responsible for post-transcriptional regulation of gene expression and may have a role in oncogenesis by acting as oncomiRs or tumor suppressor miRs. Long non-coding RNAs (lncRNAs) are heterogenous group of ncRNAs more than 200 nucleotides long, can act in cis and/or in trans, and have been also implicated in carcinogenesis. These molecules have been suggested to be promising candidates as diagnostic and prognostic biomarkers and for development of novel therapeutic approaches. In this review, we have summarized recent findings on role of these ncRNAs in HPV-negative (HPV-ve) and HPV-positive (HPV+ve) HNSCC. The available literature supports differential expression of both microRNAs and long non-coding RNAs, which include oncogenic ncRNAs (miR-21, miR-31, miR-155, miR-211, HOTAIR, and MALAT1) and tumor suppressor ncRNAs (let7d, miR-17, miR-375, miR-139, and MEG3) in HPV+ve HNSCC tumors as compared to HPV-ve tumors and they have distinct role in the pathophysiology of these two types of HNSCCs.

Abstract
Purpose To evaluate the impact of HPV16 load (VL—the number of virus genome copies per cell) and P16 expression on prognosis of patients with squamous cell carcinomas (SCCs) of head and neck (HN). Materials and methods HPV16 presence was assessed in the group of 109 patients with HNSCCs by quantitative polymerase chain reaction (qPCR). VL (assessed by qPCR) and P16 expression (evaluated by immunohistochemistry) were analysed only in the subgroup of HPV16-positive tumours. These features were correlated with 5-year overall survival (OS) and disease-free survival (DFS). Results HPV16 infection was found in 36 tumours (33.0%). Virus-positive patients had better OS and DFS than those without infection (P = 0.041 and 0.005). Among HPV16-positive HNSCCs, 18 (50.0%) had higher VL (median value > 6764.3 copies/cell) and 25 (73.5%) P16 over expression. The significant differences in OS and DFS (P = 0.008 and 0.004) were noticed according to VL, wherein 100% DFS was found for patients with higher VL. According to P16 expression, significant difference was found only for OS (P = 0.020). In multivariate analysis, VL (P = 0.045; HR = 2.795; CI 0.121–1.060) and the level of smoking (P = 0.023, HR = 2.253; CI 1.124–4.514) were independent factors affecting DFS of HPV16-positive patients. Conclusion On the basis of viral load, it is possible to differentiate prognosis of patients with HPV16-positive HNSCCs. In this subgroup, viral load has stronger prognostic potential than P16 expression.

Abstract
Human papillomavirus (HPV) associated head and neck squamous cell cancers (HNSCC) have become increasingly common in the West, but the same cannot be said about India. These cancers have a different biology and confer a better prognosis, however, its current role in the management of patients in India is not clearly defined. At the 35th Indian Cooperative Oncology Network conference held in September 2016, a panel of radiation, surgical and medical oncologists, pathologists, and basic scientists from across the country having experience in clinical research with respect to HPV in HNSCC reviewed the available literature from India. All the ideas and facts were thereafter collated in this report. Various topics of controversy in dealing with the diagnosis and management of HPV-associated HNSCC have been highlighted in this report in context to the Indian scenario. Furthermore, the prevalence of the same and its association with tobacco and high-risk sexual behavior has been touched on. Conclusively, a set of recommendations has been proposed by the panel to guide the practicing oncologists of the country while dealing with HPV-associated HNSCC.

Abstract
Background and Objective: Human papilloma virus (HPV) 16 and HPV18 have been detected in head and neck squamous cell carcinomas (HNSCC) and there is evidence that detection of HPVs would have better prognostic value than patients with HNSCC negative for HPVs. Thus, this study was conducted to evaluate frequency of HPV 16 and HPV 18 genotypes in patients with laryngeal carcinoma. Materials and methods: Fifty formalin-fixed, paraffin-embedded (FFPE) tissue blocks of laryngeal cancers were collected. Sections were prepared at 5 μm and DNA was extracted from each sample and subjected to the polymerase chain reaction (PCR) to detect HPV-16/18 DNA s. Results: All samples were squamous cell carcinomas (SCCs). Overall 14/50 (28%) were positive for HPVs, 8 (18%) with HPV-16 and 6 (12%) with HPV-18. Additionally, 2 (4%) mixed infections of HPV 16 and 18 genotypes were observed among these cases. Conclusions: Overall, 28% of HNSCC samples proved positive for HPV16 and HPV18 genotypes, two high-risk HPV types. It is important to further assess whether such viral infection, could be a risk factor in HNSCC progression.

Abstract
Head and neck cancers constitute a multifactorial global disease burden and are associated with human papilloma virus (HPV) as a possible risk factor. The aim of the study is to understand the relationship between HPV and the development of head and neck lesions in Indian patients. To this end, frequency of HPV was assessed in relation to different demographic and etiological features and correlated with patient survival. The prevalence of HPV significantly increased from mild dysplastic lesions (43.6%) to head and neck squamous cell carcinoma (HNSCC) stage IV (68.5%) with HPV 16 being pre-dominant in both dysplasia (43.8%) and HNSCC (61.5%). Similar trend was observed in increasing grades of the tumour. In invasive lesions, patients aged below the median age of onset showed significantly higher occurrence of HPV than those above it. Patients harbouring HPV showed a significantly better survival irrespective of age of onset. Likewise, better survival was observed in tobacco habit negative/HPV-positive patients, and as reflected in both univariate and multivariate analysis. Majority of the HPV 16-positive samples showed moderate/high nuclear expression of HPV E6 and E7 proteins in tumours and respective basal layer of adjacent normal tissues. Thus, our data indicate that frequent HPV infection, along with tobacco habit, is a pre-requisite factor for the development of HNSCC of Indian patients but offers a better survival even during tobacco usage, implicating its diagnostic and prognostic importance.

[PMID: 28143871 DOI: 10.1158/1078-0432.ccr-16-2936] [Citation(s) in RCA: 64] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Revised: 01/10/2017] [Accepted: 01/11/2017] [Indexed: 11/16/2022]
Abstract
Purpose: Human papillomavirus 16 (HPV-16) is an important risk factor in head and neck cancer (HNC). Studies suggest that miRNAs play an important role in cancer; however, their role in HPV-mediated oncogenesis remains largely unknown. We investigated the role of miRNAs with HPV-16 as putative target in HPV-16-mediated cancers.Experimental Design: Using in silico tools, we identified miRNAs with putative binding sequences on HPV-16 miRNAs. Hsa-miR-139-3p was identified as best candidate miRNA by luciferase reporter assay and was found to be significantly downregulated in HPV-16-positive tissues and cell lines. Overexpression/inhibition studies were performed to determine the role of miRNA in regulating oncogenic pathways.Results: Hsa-miR-139-3p was found to target high-risk HPV-16 oncogenic proteins and revive major tumor suppressor proteins (p53, p21, and p16). This resulted in inhibition of cell proliferation and cell migration, cell-cycle arrest at G2-M phase and increased cell death of HPV-16-positive cells. Analysis of The Cancer Genome Atlas (TCGA) data showed decreased expression of Hsa-miR-139-3p in HPV-16-positive HNC and cervical cancer cases, and its higher expression correlated with better survival outcome in both cases. Increased DNA methylation of Hsa-miR-139-3p harboring gene PDE2A at its promoter/CpG islands was observed in HPV-16-positive tissues and cell lines, which further correlated with Hsa-miR-139-3p expression, suggesting its role in regulating Hsa-miR-139-3p expression. Furthermore, we observed an increased sensitization of Hsa-miR-139-3p overexpressed HPV-16-positive cells to chemotherapeutic drugs (cisplatin and 5-fluorouracil).Conclusions: HPV-16-mediated downregulation of Hsa-miR-139-3p may promote oncogenesis in HNC and cervical cancer.
