Abstract
Introduction The incidence of squamous carcinoma of the oropharynx (OPSCC) has presented an increase worldwide, a fact that occurs along with a phenomenon of epidemiological transition, whose pathogenesis is linked to human papilloma virus (HPV) in a significant part of the cases. Published evidence at the Latin American level is scarce. The present study aims to evaluate the epidemiological and clinical characteristics of patients with oropharyngeal cancer treated in a public oncology reference centre in Chile. Methodology A cross-sectional study was carried out. Patients with histological confirmation of OPSCC aged 18 years or older, referred to the National Cancer Institute of Chile between 2012 and 2023 were included. The association with HPV was determined by immunohistochemistry for p16. Results 178 patients were analysed, most of them in locoregionally advanced stages involving the palatine tonsil. Seventy-seven percent were male, with a median age of 60 years. Sixty-seven percent of patients were positive for p16, with a progressive increase to 85% in the last 2 years of the study. The p16(+) patients were younger and had fewer classical risk factors. Primary treatment was radiotherapy in 94% of patients. Conclusion The epidemiological profile of patients with OPSCC treated in a Chilean public oncology referral centre reflects the epidemiological transition observed in developed countries. This change justifies the need to adapt health policies and conduct research that considers the characteristics of this new epidemiological profile.

Abstract
BACKGROUND Head and neck squamous cell carcinoma is one of the most important malignancies, worldwide. Oncogenic viruses, such as human papilloma virus (HPV) and Epstein-Barr virus (EBV), are linked to these cancers and studies suggest a possible interaction between HPV and EBV during co-infections to promote oncogenesis. Nonetheless, these reports are controversial and demand more investigations in this regard. The present work to assessed the prevalence of HPV and co-infection with EBV in oral and oropharyngeal squamous cell carcinomas. METHODS Formalin-fixed paraffin-embedded tissues were collected from 166 archived oral and oropharyngeal squamous cell carcinoma samples from Ahvaz Imam Khomeini hospital, Ahvaz, Iran, from March 2013 and December 2019. Nested-PCR was used to detect the viruses and type-specific PCR/nested-PCR and sequencing were performed for virus genotyping. RESULTS Out of the 166 specimens, 84.33% and 16.42% were from oral cavity and oropharynx, respectively; of which, 32 cases (19.3%) were HPV-positive (16.42% of oral cavity and 34.6% of oropharynx). HPV was detected in 36.36%, 25%, and 16.42% of base of tongue, tonsil, and oral tongue tumors, respectively. HPV was more associated with well differentiated tumors (24;18.04%) in compared to moderately and poorly differentiated ones. Regarding HPV-16 genotyping, 7 (21.8%) out of the 32 samples were found to be HPV-16 (4/26 (15.38%) for oropharynx and 3/140 (2.14%) for oral cavity). Moreover, 90 samples were evaluated for EBV infection and co-infection; of which, 4 (4.4%) subjects tested positive for EBV, including two cases with HPV co-infection. All the positive cases were EBV type B, from oral cavity, and histologically well differentiated. CONCLUSIONS HPV was more associated with oropharyngeal cancer. This association has been linked to various factors such as repeated oral and oropharyngeal exposure to HPV due to change in patterns of sexual behaviors; a phenomenon that may demand routine HPV vaccination.

Abstract
Some studies have addressed the prevalence of human papillomavirus (HPV) in head and neck cancer in South America; however, no studies have systematically gathered prevalence and conducted a meta-analysis. This study aims to estimate the prevalence of HPV in oral and oropharyngeal squamous cell carcinomas in South America. We performed a systematic review and metaanalysis using the following databases: PubMed, Embase, Lilacs, Medline, Scopus, and Web of Science. Data were extracted and analyzed using random-effects models to estimate the pooled prevalence of HPV. We identified 209 nonduplicated studies, of which 38 were selected. The overall prevalence of HPV was 24.31% (95% CI 16.87–32.64; I2 = 96%, pheterogeneity <0.001). HPV prevalence in oropharyngeal cancer was 17.9% (95% CI 7.6–31.4; I2 = 96%, pheterogeneity <0.001) and that in oral cavity cancer was 23.19% (95% CI 14.94–32.63; I2 = 94%, pheterogeneity <0.001). We found an overall prevalence of HPV in 24.31% of oral and oropharyngeal squamous cell carcinomas in South American patients. The prevalence of HPV was 17.9% for oropharyngeal cancer and 23.19% for oral cavity cancer.

Abstract
BACKGROUND Human papillomavirus (HPV)-driven head/neck squamous cell carcinomas (HNSCC) prevalence varies globally. We evaluated HPV DNA and p16INK4a in formalin fixed paraffin embedded (FFPE) HNSCC from Argentina, Brazil, Colombia, and Peru. METHODS HPV was genotyped by PCR-hybridization. All HPV DNA positive and some HPV DNA negative cases underwent p16INK4a immunohistochemistry. RESULTS HPV DNA was detected in 32.8%, 11.1%, and 17.8% of oropharyngeal (OPC), oral cavity (OCC) and laryngeal (LC) cancers, respectively. OPC HPV prevalence was higher in Colombia (94.7%), and Argentina (42.6%) compared to Brazil (10.6%) and Peru (0.0%). HPV-16 was the most detected. Other HPVs were found in LC. Higher rates of p16INK4a positivity were observed among HPV positive OPC/OCC cases compared to LC cases. CONCLUSIONS Our results support a role for HPV-16 in a subset of HNSCC, corroborate the heterogeneity observed in samples from different countries, and contribute additional etiological and biomarkers information in tumors of significant impact worldwide.

Abstract
Incidence of human papillomavirus (HPV)-associated oral cancers is on the rise. However, epidemiological data of this subset of cancers are limited. Dental hospital poses a unique advantage in detection of HPV-positive oral malignancies. We assessed the utility of formalin-fixed paraffin-embedded (FFPE) tissues, which are readily available, for evaluation of high-risk HPV infection in oral cancer. For protocol standardization, we used 20 prospectively collected paired FFPE and fresh tissues of histopathologically confirmed oral cancer cases reported in Oral Medicine department of a dental hospital for comparative study. Only short PCRs (~ 200 bp) of DNA isolated using a modified xylene-free method displayed a concordant HPV result. For HPV analysis, we used additional 30 retrospectively collected FFPE tissues. DNA isolated from these specimens showed an overall 23.4% (11/47) HPV positivity with detection of HPV18. Comparison of HPV positivity from dental hospital FFPE specimens with overall HPV positivity of freshly collected oral cancer specimens (n = 55) from three cancer care hospitals of the same region showed notable difference (12.7%; 7/55). Further, cancer hospital specimens showed HPV16 positivity and displayed a characteristic difference in reported sub-sites and patient spectrum. Overall, using a xylene-free FFPE DNA isolation method clubbed with short amplicon PCR, we showed detection of HPV-positive oral cancer in dental hospitals.

Abstract
Human papillomavirus is the most common sexually transmitted infection in the world and had been linked to both anogenital and oropharyngeal cancers. It causes nearly 100% of cervical cancers and an increasing portion of oropharyngeal cancers. The geographical burden of cervical HPV infection and associated cancers is not uniform and is mainly found in low middle income countries in South America, Africa, and Asia. However, HPV-positive oropharyngeal cancer is rapidly becoming more prevalent in high middle income countries. With the development of vaccines which prevent HPV infection, the World Health Organization has designated the extirpation of HPV and its associated cancers a priority. Countries that have implemented adequate vaccine programs have shown a decrease in HPV prevalence. Understanding the epidemiology of HPV and its associated cancers is fundamental in improving vaccine programs and other health programs.

Abstract
OBJECTIVE Our aim was to evaluate the prevalence of human papillomavirus (HPV)-positive tumors in a cohort of patients with oropharyngeal squamous cell carcinoma (OPSCC) at a single center in southern Brazil and determine the short-term prognostic factors in this sample. STUDY DESIGN Ninety-one consecutive patients with newly diagnosed primary OPSCC between January 2017 and December 2019 were retrospectively included. Demographic, clinical, pathologic, and survival data were collected. HPV status was determined by using p16 immunohistochemistry. RESULTS The overall prevalence of HPV-positive (HPV+) OPSCC was 20.9%. Patients with HPV+ tumors presented a nodal metastasis as the first clinical sign (P = .02); reported less alcohol (P < .001) and tobacco use (P < .001); exhibited lower tumor stages (P < .001) and higher microscopic grades (P = .01); and had higher chances of having resectable tumors (P = .008). p16-negative status (P = .01); unresectable/inoperable tumors (P < .001); presence of nodal metastasis (P = .005); and higher American Joint Committee on Cancer (AJCC) stage (P = .002) were significantly associated with worse disease-specific survival. CONCLUSIONS The prevalence of HPV+ OPSCC in southern Brazil is relatively low, and p16-positive status was associated with Better prognosis. Higher AJCC stage, nodal metastasis, and unresectability/inoperability were associated with the highest hazard ratios for death resulting from OPSCC.

Abstract
INTRODUCTION In recent years, an association between HPV-16 and oropharyngeal cancers has been reported. Therefore, it is necessary to evaluate whether vaccination decreases the exposure of HPV-16 in the oral cavity. OBJECTIVE To evaluate the effect of vaccination on oral HPV-16 infection in high school students in the city of Cali, Colombia. METHODS In this cross-sectional study, HPV-16 DNA was detected in samples from the oral cavity and throat of 1,784 high school students of both genders, aged 14-17 years old, in 21 schools in the city of Cali, Colombia. The number in vaccinated girls were 944 vs., 95 unvaccinated girls and 745 unvaccinated boys. RESULTS The HPV exposure percentages were: 0.7% in vaccinated girls, 3.2% in unvaccinated girls and 2.3% in unvaccinated boys. The odds ratio (OR) of detection of HPV-16 in vaccinated versus unvaccinated students was 0.28 (95% CI: 0.07-0.88), representing a 72% reduction in HPV-16 detection in students immunized with two doses. The odds of detection of HPV-16 in unvaccinated male students were 3.6 times those of vaccinated girls (OR = 3.6, 95% CI: 1.21-12.81) and increased to almost eight-fold in boys who had initiated sexual activity (OR = 7.74, 95% CI: 1.53-75.09). CONCLUSIONS HPV vaccination was associated with the reduction of HPV-16 exposure percentages in the oral and oropharyngeal cavity.

Abstract
There are inconsistent reports regarding the role of HPV in the origin and progression of oral squamous cell carcinoma (OSCC). The observed heterogeneity was mainly attributed to the social and cultural habits of the enrolled cases, discrepancies in the nature of samples procured and varying sensitivity of the assays employed for detection of HPV. The objective of this study was to assess the prevalence of HPV in OSCC in South West India. This was a cross sectional study conducted over a period extending from October 2015 to June 2017. This study involved Department of ENT-Head and Neck Surgery and Department of Virology, Manipal Academy of Higher Education. Fifty histologically confirmed oral squamous cell carcinoma patients undergoing wide local excision of the tumour were enrolled for the study. Intraoperatively 4-5 mm of tissue samples were transported in sterile normal saline at 4-80 °C. The primary screening of tissue samples was performed by nested PCR using PGMY09/11 consensus primers and GP5+/6+ consensus primers and TaqMan based real time multiplex PCR for HPV-16, HPV-18, HPV-31 and HPV-45. All samples tested negative for HPV DNA by conventional nested PCR and TaqMan based real-time Multiplex PCR ruling out four common HPV subtypes such as HPV-16, 18, 31, 45. We did not find presence of HPV DNA in the tissues of patients with OSCC from southwest India. However, studies with more geographic representation from other parts of India are required before generalising our findings.

Abstract
This commentary explores the distribution of human papilloma virus (HPV) and HPV-related diseases, and factors affecting attitudes towards HPV, HPV-related diseases, and HPV vaccination in the Latin American Andean region. Lack of knowledge of HPV, known negative attitudes or incorrect assumptions about HPV, HPV-related diseases, and HPV vaccination provide a basis upon which to develop targeted HPV awareness and preventive health media campaigns. For maximal effect, media campaigns should use the internet, radio, and television to address health care providers, parents, and students. Additional programming can be developed for clinics to use in-house with their clients. Ministries of Education, Finance, and Health all have roles to play to increase national HPV, HPV-related diseases, and HPV vaccination awareness.

Abstract
Introduction Molecular studies about carcinomas of the oral cavity and oropharynx demonstrate the presence of human papilomavirus genome in these tumors, reinforcing the participation of human papilomavirus in oral carcinogenesis. Objectives This study aimed to determine the prevalence of human papilomavirus and genotype distribution of HPV16 and HPV18 in oral cavity and oropharynx carcinomas, as well as their association with clinical characteristics of the tumors. Methods This is a retrospective study, with clinical data collected from 82 patients. Human papilomavirus detection was conducted on specimens of oral cavity and oropharynx carcinomas included in paraffin blocks. Patients were assisted in a cancer reference center, in the central region of Brazil, between 2005 and 2007. Polymerase chain reaction was used for the detection and genotyping of human papilomavirus. Results Among the patients evaluated, 78% were male. The average age of the group was about 58 years. Risk factors, such as smoking (78%) and alcohol consumption (70.8%) were recorded for the group. HPV DNA was detected in 21 cases (25.6%; 95% confidence interval 16.9–36.6) of which 33.3% were HPV16 and 14.3% were HPV18. The presence of lymph node metastases and registered deaths were less frequent in human papilomavirus positive tumors, suggesting a better prognosis for these cases; however, the differences between the groups were not statistically significant. Conclusion The results obtained in the present study, with respect to the presence of the high-risk HPV16 and HPV18 genotypes, highlight the importance of human papilomavirus vaccination in the control of oral cavity and oropharynx carcinomas.

Abstract
INTRODUCTION One of the risk factors for squamous cell oropharyngeal carcinoma is infection with the human papilloma virus (HPV), with prevalences that vary depending on the geographical region. OBJECTIVE To identify the most frequent HPV viral types in oropharyngeal cancer, the levels of expression and the physical condition of the viral genome. MATERIALS AND METHODS Forty-six patients were included in the study from among those attending head and neck surgical services in the cities of Bogotá, Manizales and Bucaramanga. In the histopathological report all study samples were characterized as oropharyngeal squamous cell carcinoma. DNA extraction was subsequently performed for HPV genotyping and to determine the physical state of the viral genome, as well as RNA to determine viral transcripts using real-time PCR. RESULTS HPV prevalence in tumors was 21.74% (n=10) and the most common viral type was HPV-16 (nine cases). Viral expression for HPV-16 was low (one of 11 copies) and the predominant physical state of the virus was mixed (eight cases), with disruption observed at the E1 - E2 binding site (2525 - 3720 nucleotides). CONCLUSION The prevalence of HPV associated with oropharyngeal carcinoma among the Colombian study population was 21.7%, which is relatively low. The most frequent viral type was HPV-16, found in a mixed form and with low expression of E7, possibly indicating a poor prognosis for these patients.

Abstract
Human papillomavirus-associated oropharynx cancer (HPVA-OPC) is rapidly increasing in incidence and has unique epidemiologic, molecular, and biologic characteristics. Despite being recognized as having superior prognosis, current evidence does not support less intense therapy compared with HPV-negative OPC. Current combined modality therapies confer a significant risk of morbidity, and patients with HPVA-OPC have a younger median age. These patients, therefore, live longer with the adverse effects of treatment, and this spurs the development of treatment deintensification trials that attempt to decrease treatment-related morbidity without compromising efficacy. Many radiation and chemotherapy de-escalation trials are underway. Minimally invasive surgical techniques are also being evaluated. It is important to identify the ideal patient group for treatment deintensification and to define prognostic risk groups to avoid undertreating the poorer-risk subset in HPVA-OPC, and validated biomarkers are needed to identify patients with the best prognosis. Significant smoking exposure mitigates the favorable prognosis of HPVA-OPC. Currently, less intense treatment is an option only in the setting of clinical trials, and patients with HPVA-OPC should be offered clinical trial options whenever they are available. Finally, recognition of novel therapeutic targets and signaling pathways is critical to the development of new treatment strategies that are desperately needed for patients with poor risk and those with recurrent and metastatic disease.

Prevalence of HPV infection in head and neck carcinomas shows geographical variability: a comparative study from Brazil and Germany. Virchows Arch 2015; 466:685-93. [PMID: 25820374 DOI: 10.1007/s00428-015-1761-4] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2015] [Revised: 02/16/2015] [Accepted: 03/11/2015] [Indexed: 10/23/2022]
Abstract
Rising prevalence rates of high-risk human papillomaviruses (hrHPV) infection in oropharyngeal carcinoma (up to 80 %) have been reported in North America and Scandinavia. We have analysed 424 German and 163 Brazilian head and neck squamous cell carcinomas (HNSCC) from the oral cavity (OSCC), oropharynx (OPSCC) and hypopharynx (HPSCC) using p16 immunohistochemistry, HPV DNA PCR and sequencing, hrHPV DNA in situ hybridisation (ISH) and hrHPV E6/E7 RNA ISH. In the German series, 52/424 cases (12.3 %) were p16-positive/hrHPV-positive (OSCC 3.8 % [10/265], OPSCC 34.4 % [42/122], HPSCC 0 % [0/37]). In addition, there were 9 cases that were p16-positive/hrHPV-negative (5 OPSCC and 4 OSCC). In the Brazilian series, the overall hrHPV DNA prevalence by PCR was 11.0 % ([18/163]; OSCC 6 % [5/83], OPSCC 15.5 % [11/71], HPSCC 22.2 % [2/9]). Ten of these cases were hrHPV-positive/p16-positive. The remaining 8 hrHPV-positive/p16-negative cases were also negative in both ISH assays. Furthermore, 5 p16-positive/hrHPV-negative cases (2 OPSCC and 3 OSCC) were identified. In both series, HPV16 was by far the most common HPV type detected. We confirm that regardless of geographical origin, the highest hrHPV prevalence in HNSCC is observed in oropharyngeal carcinomas. The proportion of HPV-associated OPSCC was substantially higher in the German cohort than in the Brazilian series (34.4 vs. 15.5 %), and in both groups, the prevalence of hrHPV in OPSCC was much lower than in recent reports from North America and Scandinavia. We suggest, therefore, that it may be possible to define areas with high (e.g. USA, Canada, Scandinavia), intermediate (e.g. Germany) and low (e.g. Brazil) prevalences of HPV infection in OPSCC.

Unexpected inverse correlation between Native American ancestry and Asian American variants of HPV16 in admixed Colombian cervical cancer cases. INFECTION GENETICS AND EVOLUTION 2014; 28:339-48.

Abstract
BACKGROUND European (E) variants of HPV 16 are evenly distributed among world regions, meanwhile Non-European variants such as European-Asian (EAs), Asian American (AA) and African (Af) are mostly confined to Eastern Asia, The Americas and African regions respectively. Several studies have shown that genetic variation of HPV 16 is associated with the risk of cervical cancer, which also seems to be dependent on the population. This relationship between ethnicity and variants have led to the suggestion that there is co-evolution of variants with humankind. Our aim was to evaluate the relationship between the individual ancestry proportion and infection with HPV 16 variants in cervical cancer. METHODS We examined the association between ancestry and HPV 16 variants in samples of 82 cervical cancer cases from different regions of Colombia. Individual ancestry proportions (European, African and Native American) were estimated by genotyping 106 ancestry informative markers. Variants were identified by PCR amplification of the E6 gene, followed by reverse line blot hybridization (RLB) with variants specific probes. RESULTS Overall European (E) and Asian American (AA) variants frequency was 66.5% and 33.5% respectively. Similar distribution was observed in cases with higher proportions of European or African ancestry. A higher Native American ancestry was significantly associated with higher frequency of E variants (median ancestry>23.6%, Age and place of birth adjusted OR: 3.55, 95% CI: 1.26-10.03, p=0.01). Even further, an inverse geographic correlation between Native American ancestry and frequency of infections with AA variants was observed (ρ=-0.825, p=0.008). Regions with higher proportion of Native American ancestry had a lower frequency of AA variants of HPV 16. CONCLUSIONS This study suggests replacement of AA variants by E variants of human papillomavirus 16 in cervical cancer cases with high Native American ancestry.
