    ABSTRACT: We hypothesized that viral and host factors impact the serologic responses to HPV early antigens in HPV-positive oropharyngeal cancer (HPVOPC). We conducted a multicenter study to measure HPV16-specific IgG among patients with HPVOPC, their long-term sexual partners, and healthy volunteers. Risk factor surveys and rinse and gargle specimens were collected. Peripheral blood samples at diagnosis were evaluated for IgG Abs to HPV16 antigens using a programmable ELISA assay. Predictors for HPV16 serologic responses were evaluated using univariate and multivariable linear regression. 116 patients with HPVOPC, 43 partners, and 81 healthy volunteers were enrolled and had baseline sera for analysis. Cases were primarily male (90%), with a median age of 56years. Abs to E1, E2, E6 or E7 antigens were detected more often in HPVOPC compared with volunteers or partner sera (p<0.0001). HPV16 Abs to at least one early protein (E1, E2, E4, E5, E6, or E7) were detected in the sera of 90.6% of cases, 0% of partners and 7.4% of healthy volunteers. Gender, race, sexual behavior, and viral integration were not associated with antibody response. Younger age and higher oral HPV16 copy number were associated with higher HPV16 E6 and NE2 antibody levels. HPV16 seroreactivity is commonly detected among patients with HPVOPC at diagnosis, but not among partners or healthy volunteers. Seroreactivity among cases are correlated with viral load and stage and not with other demographic or behavioral factors. Positive HPV16 serology was strongly associated with HPV 16 oropharyngeal cancer. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: The association between oral HPV16 DNA viral load and infection clearance was evaluated among 88 individuals with oral HPV16 infection identified within a prospective cohort of 1,470 HIV-infected and uninfected individuals. Oral rinses were collected semi-annually for up to five years. Oral HPV16 viral load at the first positive test was significantly associated with time to clearance of infection (continuous p-trends<0.01). Notably, clearance rates by 24-month were 41% and 94% in the highest and lowest HPV16 viral load tertiles (p=0.03), respectively. High oral HPV16 viral load warrants consideration as a biomarker for infection persistence, the presumed precursor of HPV16-associated oropharyngeal cancer. © The Author 2015.

    ABSTRACT: Little is known about the epidemiology or risk factors for oral human papillomavirus (HPV) in HIV-infected youth. The objectives of this study were to determine the prevalence and correlates of oral HPV infection and to explore the association between HPV vaccination and oral infection in HIV-infected youth. Youth 12 to 24 years of age with behaviorally acquired HIV were recruited for this cross-sectional study. Procedures involved medical chart review, survey, and collection of an oral rinse sample. Univariable and multivariable logistic regression models were used to determine whether demographic, behavioral, immunologic, and virologic factors and history of vaccination were significantly associated with oral HPV infection. Mean age of the 272 participants was 21.5 years; 64% were non-Hispanic black and 20.2% were Hispanic; and 10.8% of men compared with 20.3% of women were fully vaccinated. Human papillomavirus prevalence was 19.7% in men and 18.6% in women (P = 1.0). Only men were positive for vaccine-type HPV: 5.6% were positive for HPV-6, HPV-11, HPV-16, and/or HPV-18, and 4.2% were positive for HPV-16 and/or HPV-18. Among men who were fully vaccinated, none were positive for HPV-6, HPV-11, HPV-16, and/or HPV-18, compared with 12 (6.3%) of men who were not fully vaccinated (P = 0.37). Two variables were marginally associated with oral HPV (P < 0.10): marijuana use in the previous 3 months and lower CD4+ T-cell count. Prevalence rates of oral HPV were relatively high in this population of HIV-infected youth and were similar in male and female youth. No fully vaccinated men were infected with vaccine-type HPV.

    ABSTRACT: The incidence of human papillomavirus (HPV)-positive oropharyngeal cancers is higher and rising more rapidly among men than women in the United States (U.S.) for unknown reasons. We compared the epidemiology of oral oncogenic HPV infection between men and women aged 14-69 years (N=9,480) within the U.S. National Health and Nutritional Examination Surveys (NHANES) 2009-2012. HPV presence was detected in oral DNA by PCR. Analyses were stratified by gender and utilized NHANES sample weights. Oral oncogenic HPV prevalence was higher among men than women (6.6% vs. 1.5%, p<0.001), corresponding to 7.07 million men vs. 1.54 million women with prevalent infection at any point in time during 2009-2012. Prevalence increased significantly with age, current smoking, and lifetime number of sexual partners for both genders (adjusted p-trends<0.02). However, men had more partners than women (mean=18 vs. 7, p<0.001). Although oncogenic HPV prevalence was similar for men and women with 0-1 lifetime partners, the male-female difference in prevalence significantly increased with number of lifetime partners (adjusted prevalence differences for none, one, 2-to-5, 6-to-10, 11-to-20, and 20+ partners=1.0%, 0.5%, 3.0%, 5.7%, 4.6%, and 9.3%, respectively). Importantly, the per-sexual-partner increase in prevalence was significantly stronger among men than women (adjusted Synergy Index=3.3; 95%CI=1.1-9.7), and this increase plateaued at 25 lifetime partners among men vs.10 partners among women. Our data suggest that the higher burden of oral oncogenic HPV infections and HPV-positive oropharyngeal cancers among men than women arises in part from higher number of lifetime sexual partners and stronger associations with sexual behaviors among men.

    ABSTRACT: Individuals with human papillomavirus (HPV) infections can develop IgG antibodies to HPV proteins including the L1 capsid and E6 and E7 oncoproteins. Evidence on whether L1 antibodies reduce the risk of cervical HPV infection is mixed, but this has not been explored for oral HPV infections. Antibodies to HPV16's E6 oncoprotein have been detected in some oropharyngeal cancer cases years before cancer diagnosis, but it is unknown if these antibodies are associated with oral HPV16 DNA. Enzyme-linked immunosorbent assays tested for serum antibodies to HPV16's L1 capsid in 463 HIV-infected and 293 HIV-uninfected adults, and for antibodies to recombinantly expressed E6 and E7 oncoproteins to HPV16 in 195 HIV-infected and 69 HIV-uninfected cancer-free participants at baseline. Oral rinse samples were collected semiannually for up to 3 years and tested for HPV DNA using PGMY 09/11 primers. Adjusted Poisson, logistic, and Wei-Lin-Weissfeld regression models were used. Human papillomavirus 16 L1 seroreactivity did not reduce the subsequent risk of incident oral HPV16 infection in unadjusted (hazard ratio, 1.4; 95% confidence interval, 0.59-3.3) or adjusted (adjusted hazard ratio = 1.1; 95% confidence interval, 0.41-3.0) analysis. Antibodies to HPV16 E6 and E7 oncoproteins were detected in 7.6% and 3.4% of participants, respectively, but they were not associated with baseline oral HPV16 DNA prevalence or oral HPV16 persistence (each P > 0.40). Naturally acquired HPV16 L1 antibodies did not reduce the risk of subsequent oral HPV16 infection. Human papillomavirus 16 E6 and E7 seropositivity was not a marker for oral HPV16 infection in this population without HPV-related cancer.

    ABSTRACT: National Comprehensive Cancer Network guidelines recommend patients with head and neck cancer (HNC) receive treatment at centers with expertise, but whether provider experience affects survival is unknown. The effect of institutional experience on overall survival (OS) in patients with stage III or IV HNC was investigated within a randomized trial of the Radiation Therapy Oncology Group (RTOG 0129), which compared cisplatin concurrent with standard versus accelerated fractionation radiotherapy. As a surrogate for experience, institutions were classified as historically low- (HLACs) or high-accruing centers (HHACs) based on accrual to 21 RTOG HNC trials (1997 to 2002). The effect of accrual volume on OS was estimated by Cox proportional hazards models. Median RTOG accrual (1997 to 2002) at HLACs was four versus 65 patients at HHACs. Analysis included 471 patients in RTOG 0129 (2002 to 2005) with known human papillomavirus and smoking status. Patients at HLACs versus HHACs had better performance status (0: 62% v 52%; P = .04) and lower T stage (T4: 26.5% v 35.3%; P = .002) but were otherwise similar. Radiotherapy protocol deviations were higher at HLACs versus HHACs (18% v 6%; P < .001). When compared with HHACs, patients at HLACs had worse OS (5 years: 51.0% v 69.1%; P = .002). Treatment at HLACs was associated with increased death risk of 91% (hazard ratio [HR], 1.91; 95% CI, 1.37 to 2.65) after adjustment for prognostic factors and 72% (HR, 1.72; 95% CI, 1.23 to 2.40) after radiotherapy compliance adjustment. OS is worse for patients with HNC treated at HLACs versus HHACs to cooperative group trials after accounting for radiotherapy protocol deviations. Institutional experience substantially influences survival in locally advanced HNC. © 2014 by American Society of Clinical Oncology.

    ABSTRACT: Human papillomavirus (HPV) causes the majority of oropharyngeal cancers in the United States, yet the risk factors for and natural history of oral HPV infection are largely unknown. In 2010-2011, a US-based longitudinal cohort study of 761 human immunodeficiency virus (HIV)-infected and 469 at-risk HIV-uninfected participants from the Multicenter AIDS Cohort Study and the Women's Interagency HIV Study was initiated. Semiannually collected oral rinses were evaluated for 37 HPV genotypes using the Roche LINEAR ARRAY HPV Genotyping Test (Roche Molecular Systems, Pleasanton, California), and factors associated with oral HPV incidence and clearance were explored using adjusted Wei-Lin-Weissfeld modeling. Through 2013, the 2-year cumulative incidence of any type of oral HPV infection was 34% in HIV-infected persons and 19% in HIV-uninfected persons. However, many of these infections cleared. Seven percent of incident infections and 35% of prevalent infections persisted for at least 2 years. After adjustment for other risk factors, HIV infection (adjusted hazard ratio = 2.3, 95% confidence interval: 1.7, 3.2), reduced current CD4 cell count, and increased numbers of oral sex and "rimming" partners increased the risk of incident oral HPV infection, whereas male sex, older age, and current smoking increased the risk of oral HPV persistence (each P < 0.05). This helps explain the consistent associations observed between these factors and prevalent oral HPV infection in previous cross-sectional studies. © The Author 2014.

    ABSTRACT: Although p16 protein expression, a surrogate marker of oncogenic human papillomavirus (HPV) infection, is recognized as a prognostic marker in oropharyngeal squamous cell carcinoma (OPSCC), its prevalence and significance have not been well established in cancer of the oral cavity, hypopharynx, or larynx, collectively referred as non-OPSCC, where HPV infection is less common than in the oropharynx.

    ABSTRACT: Oral HPV infection, the cause of most oropharyngeal cancer in the U.S., is not well studied among high-risk young adults. Men (n = 340) and women (n = 270) aged 18-25 years attending Baltimore County STD clinics were recruited if they declined HPV vaccination. Each participant had a 30-second oral rinse and gargle sample tested for 37 types of HPV DNA, and a risk-factor survey. Factors associated with prevalent infection were explored using log binomial regression. Men had higher prevalence of any oral HPV (15.3% vs. 7.8%, p = 0.004) and vaccine-type oral HPV (i.e., HPV16/18/6/11: 5.0% vs. 1.1%, p = 0.007) infection than women. In multivariate analysis, male gender (aPR = 1.93, 95% CI = 1.10-3.39), number of recent oral sex partners (p-trend = 0.013) and having ever performed oral sex on a woman (aPR = 1.73, 95% CI = 1.06-2.82) were associated with increased oral HPV prevalence. Performing oral sex on a woman may confer higher risk of oral HPV acquisition than performing oral sex on a man.

    ABSTRACT: Combining cisplatin or cetuximab with radiation improves overall survival (OS) of patients with stage III or IV head and neck carcinoma (HNC). Cetuximab plus platinum regimens also increase OS in metastatic HNC. The Radiation Therapy Oncology Group launched a phase III trial to test the hypothesis that adding cetuximab to the radiation-cisplatin platform improves progression-free survival (PFS).

    ABSTRACT: Low socioeconomic status has been reported to be associated with head and neck cancer risk. However, previous studies have been too small to examine the associations by cancer subsite, age, sex, global region, and calendar time, and to explain the association in terms of behavioural risk factors. Individual participant data of 23,964 cases with head and neck cancer and 31,954 controls from 31 studies in 27 countries pooled with random effects models. Overall, low education was associated with an increased risk of head and neck cancer (OR = 2·50; 95%CI 2·02- 3·09). Overall one-third of the increased risk was not explained by differences in the distribution of cigarette smoking and alcohol behaviours; and it remained elevated among never users of tobacco and non-drinkers (OR = 1·61; 95%CI 1·13 - 2·31). More of the estimated education effect was not explained by cigarette smoking and alcohol behaviours: in women than in men, in older than younger groups, in the oropharynx than in other sites, in South/Central America than in Europe/North America, and was strongest in countries with greater income inequality. Similar findings were observed for the estimated effect of low vs high household income. The lowest levels of income and educational attainment were associated with more than 2-fold increased risk of head and neck cancer, which is not entirely explained by differences in the distributions of behavioural risk factors for these cancers, and which varies across cancer sites, sexes, countries, and country income inequality levels. © 2014 Wiley Periodicals, Inc.

    ABSTRACT: Purpose Risk of cancer progression is reduced for patients with human papillomavirus (HPV) -positive oropharynx cancer (OPC) relative to HPV-negative OPC, but it is unknown whether risk of death after progression is similarly reduced. Patients and Methods Patients with stage III-IV OPC enrolled onto Radiation Therapy Oncology Group trials 0129 or RTOG 0522 who had known tumor p16 status plus local, regional, and/or distant progression after receiving platinum-based chemoradiotherapy were eligible for a retrospective analysis of the association between tumor p16 status and overall survival (OS) after disease progression. Rates were estimated by Kaplan-Meier method and compared by log-rank; hazard ratios (HRs) were estimated by Cox models. Tests and models were stratified by treatment protocol. Results A total of 181 patients with p16-positive (n = 105) or p16-negative (n = 76) OPC were included in the analysis. Patterns of failure and median time to progression (8.2 v 7.3 months; P = .67) were similar for patients with p16-positive and p16-negative tumors. After a median follow-up period of 4.0 years after disease progression, patients with p16-positive OPC had significantly improved survival rates compared with p16-negative patients (2-year OS, 54.6% v 27.6%; median, 2.6 v 0.8 years; P < .001). p16-positive tumor status (HR, 0.48; 95% CI, 0.31 to 0.74) and receipt of salvage surgery (HR, 0.48; 95% CI; 0.27 to 0.84) reduced risk of death after disease progression whereas distant versus locoregional progression (HR, 1.99; 95% CI, 1.28 to 3.09) increased risk, after adjustment for tumor stage and cigarette pack-years at enrollment. Conclusion Tumor HPV status is a strong and independent predictor of OS after disease progression and should be a stratification factor for clinical trials for patients with recurrent or metastatic OPC.

    ABSTRACT: Although human papillomavirus detection in cervical lymph nodes of head and neck squamous cell cancers (HNSCC) of unknown primary site (UP) is indicative of a primary tumor of the oropharynx (OP), localization can remain elusive. Therefore, we investigated ultrasonography (US) for the identification of the primary tumor. Eligible cases had HNSCC of UP after evaluation by a head and neck surgical oncologist. Controls were healthy volunteers. Transcervical and intraoral ultrasonography was performed by a standard protocol using convex (3.75-6.0MHz and 5-7.5MHz) transducers. US findings were compared with operative examination (exam under anesthesia, direct laryngoscopy) and biopsies. The primary outcome of interest was the presence or absence of a lesion on US. 10 cases and 20 controls were enrolled. PET/CT scans were negative/nonspecific (9), or suspicious (1) for a primary lesion. On US, predominantly hypoechoic (9 of 10) lesions were visualized consistent with base of tongue (n=7) or tonsil (n=3) primary tumors. On operative examination, 5 of 10 were appreciated. Two additional primaries were confirmed with biopsies "directed" by preoperative US. This represents an overall diagnostic rate of 70%, which is 20% higher than our detection rate for 2008-2010. The three cases in which a suspicious lesion was visualized on US, yet remained UP despite further interventions, could represent false positives, misclassification or operator variability. No lesions were suspected among the controls. Ultrasound has promise for detection of UPs of the OP and therefore warrants further investigation.

    ABSTRACT: To better understand oral human papillomavirus (HPV) infection and cancer risk among long-term sexual partners of patients with HPV-positive oropharyngeal cancer (HPV-OPC). An oral rinse sample, risk factor survey, cancer history, and oral examination (partners only) were collected from patients with HPV-OPC and their partners. Oral rinse samples were evaluated for 36 types of HPV DNA using PGMY 09/11 primers and line-blot hybridization and HPV16 copy number using quantitative polymerase chain reaction. Oral HPV prevalence was compared with infection among those age 45 to 65 years using National Health and Nutrition Examination Survey (NHANES) 2009-2010. A total of 164 patients with HPV-OPC and 93 of their partners were enrolled. Patients were primarily men (90%), were never-smokers (51%), and had performed oral sex (97%), with a median age of 56 years; they had a high prevalence of oncogenic oral HPV DNA (61%) and oral HPV16 DNA (54%) at enrollment. Female partners had comparable oncogenic oral HPV prevalence compared with members of the general population of the same age (1.2% v 1.3%). Among the six male partners, no oncogenic oral HPV infections were detected. No precancers or cancers were identified during partner oral cancer screening examinations. However, a history of cervical disease was reported by nine partners (10.3%) and two female patients (11.8%), and three patients (2.0%) reported a previous partner who developed invasive cervical cancer. Oral HPV16 DNA is commonly detected among patients with HPV-OPC at diagnosis, but not among their partners. Partners of patients with HPV-OPC do not seem to have elevated oral HPV infection compared with the general population.

    ABSTRACT: We investigated the association of demographic and behavioral factors with oral HPV viral load for 18 high-risk types among 211 individuals with prevalent high-risk HPV within NHANES 2009-2010. Factors independently associated with HPV viral load above the median included older age (per year increase, OR=1.04, 95%CI=1.01-1.07, p=0.004) and intensity of current smoking (p-trend<0.001). HPV viral load was marginally higher among men than women (55.7% vs. 32.8% above median; p=0.069) and increased marginally with increasing alcohol use (p-trend=0.062). In conclusion, older age and current smoking are associated with high oral high-risk HPV viral load among individuals with a prevalent infection.

    ABSTRACT: Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy worldwide, and patient outcomes using current treatments remain poor. Tumor development is etiologically associated with tobacco or alcohol use and/or human papillomavirus (HPV) infection. HPV-positive HNSCCs, which frequently harbor wild-type p53, carry a more favorable prognosis and are a biologically distinct subgroup when compared with their HPV-negative counterparts. HPV E7 induces expression of the human DEK gene, both in vitro and in vivo. In keratinocytes, DEK overexpression is sufficient for causing oncogenic phenotypes in the absence of E7. Conversely, DEK loss results in cell death in HPV-positive cervical cancer cells at least in part through p53 activation, and Dek knockout mice are relatively resistant to the development of chemically induced skin papillomas. Despite the established oncogenic role of DEK in HPV-associated cervical cancer cell lines and keratinocytes, a functional role of DEK has not yet been explored in HNSCC. Using an established transgenic mouse model of HPV16 E7-induced HNSCC, we demonstrate that Dek is required for optimal proliferation of E7-transgenic epidermal cells and for the growth of HNSCC tumors. Importantly, these studies also demonstrate that DEK protein is universally upregulated in both HPV-positive and -negative human HNSCC tumors relative to adjacent normal tissue. Furthermore, DEK knockdown inhibited the proliferation of HPV-positive and -negative HNSCC cells, establishing a functional role for DEK in human disease. Mechanistic studies reveal that attenuated HNSCC cell growth in response to DEK loss was associated with reduced expression of the oncogenic p53 family member, ΔNp63. Exogenous ΔNp63 expression rescued the proliferative defect in the absence of DEK, thereby establishing a functional DEK-ΔNp63 oncogenic pathway that promotes HNSCC. Taken together, our data demonstrate that DEK stimulates HNSCC cellular growth and identify ΔNp63 as a novel DEK effector.Oncogene advance online publication,10 March 2014; doi:10.1038/onc.2014.15.
