Hernandez BY , Rahman M , Lynch CF , Cozen W , Unger ER , Steinau M , Thompson T , Saber MS , Altekruse SF , Goodman MT , Powers A , Lyu C , Saraiya M . Papillomavirus Res 2016 2 52-55 We examined p16 expression in tumors from a population-based sample of laryngeal cancer cases diagnosed in the U.S. Samples had been previously genotyped for HPV DNA. Overall, p16 expression was observed in laryngeal tissue from 8 of 101 (7.9%) cases. p16 expression was observed in 2 of 16 (12.5%) cases previously determined to be HPV DNA positive. The two cases dually positive for p16 and HPV DNA were non-keratinizing SCC and papillary SCC tumors that were positive for genotypes 18 and 35/89, respectively. Positivity for p16 and/or HPV DNA was not associated with 5-year survival (log-rank p value=0.55). Our findings support a limited role of HPV in laryngeal carcinogenesis. p16 is not a reliable surrogate for HPV status in laryngeal cancers and is not a predictor of laryngeal cancer survival. |

J Natl Cancer Inst 2015 107 (6) djv086 BACKGROUND: This study sought to determine the prevaccine type-specific prevalence of human papillomavirus (HPV)-associated cancers in the United States to evaluate the potential impact of the HPV types in the current and newly approved 9-valent HPV vaccines. METHODS: The Centers for Disease Control and Prevention partnered with seven US population-based cancer registries to obtain archival tissue for cancers diagnosed from 1993 to 2005. HPV testing was performed on 2670 case patients that were fairly representative of all participating cancer registry cases by age and sex. Demographic and clinical data were evaluated by anatomic site and HPV status. Current US cancer registry data and the detection of HPV types were used to estimate the number of cancers potentially preventable through vaccination. RESULTS: HPV DNA was detected in 90.6% of cervical, 91.1% of anal, 75.0% of vaginal, 70.1% of oropharyngeal, 68.8% of vulvar, 63.3% of penile, 32.0% of oral cavity, and 20.9% of laryngeal cancers, as well as in 98.8% of cervical cancer in situ (CCIS). A vaccine targeting HPV 16/18 potentially prevents the majority of invasive cervical (66.2%), anal (79.4%), oropharyngeal (60.2%), and vaginal (55.1%) cancers, as well as many penile (47.9%), vulvar (48.6%) cancers: 24 858 cases annually. The 9-valent vaccine also targeting HPV 31/33/45/52/58 may prevent an additional 4.2% to 18.3% of cancers: 3944 cases annually. For most cancers, younger age at diagnosis was associated with higher HPV 16/18 prevalence. With the exception of oropharyngeal cancers and CCIS, HPV 16/18 prevalence was similar across racial/ethnic groups. CONCLUSIONS: In the United States, current vaccines will reduce most HPV-associated cancers; a smaller additional reduction would be contributed by the new 9-valent vaccine. |

Hernandez BY , Goodman MT , Lynch CF , Cozen W , Unger ER , Steinau M , Thompson T , Saber MS , Altekruse SF , Lyu C , Saraiya M . PLoS One 2014 9 (12) e115931 PURPOSE: Human papillomavirus (HPV) is a major risk factor for specific cancers of the head and neck, particularly malignancies of the tonsil and base of the tongue. However, the role of HPV in the development of laryngeal cancer has not been definitively established. We conducted a population-based, cancer registry study to evaluate and characterize the genotype-specific prevalence of HPV in invasive laryngeal cancer cases diagnosed in the U.S. METHODS: The presence of genotype-specific HPV DNA was evaluated using the Linear Array HPV Genotyping Test and the INNO-LiPA HPV Genotyping Assay in formalin-fixed paraffin embedded tissue from 148 invasive laryngeal cancer cases diagnosed in 1993-2004 within the catchment area of three U.S. SEER cancer registries. RESULTS: HPV DNA was detected in 31 of 148 (21%) invasive laryngeal cancers. Thirteen different genotypes were detected. Overall, HPV 16 and HPV 33 were the most commonly detected types. HPV was detected in 33% (9/27) of women compared with 18% (22/121) of men (p = 0.08). After adjustment for age and year of diagnosis, female patients were more likely to have HPV-positive laryngeal tumors compared to males (adjusted OR 2.84, 95% CI 1.07-7.51). Viral genotype differences were also observed between the sexes. While HPV 16 and 18 constituted half of HPV-positive cases occurring in men, among women, only 1 was HPV 16 positive and none were positive for HPV 18. Overall 5-year survival did not vary by HPV status. CONCLUSIONS: HPV may be involved in the development of a subset of laryngeal cancers and its role may be more predominant in women compared to men. |
Human papillomavirus prevalence in oropharyngeal cancer before vaccine introduction, United States
Steinau M , Saraiya M , Goodman MT , Peters ES , Watson M , Cleveland JL , Lynch CF , Wilkinson EJ , Hernandez BY , Copeland G , Saber MS , Hopenhayn C , Huang Y , Cozen W , Lyu C , Unger ER . Emerg Infect Dis 2014 20 (5) 822-8 We conducted a study to determine prevalence of HPV types in oropharyngeal cancers in the United States and establish a prevaccine baseline for monitoring the impact of vaccination. HPV DNA was extracted from tumor tissue samples from patients in whom cancer was diagnosed during 1995-2005. The samples were obtained from cancer registries and Residual Tissue Repository Program sites in the United States. HPV was detected and typed by using PCR reverse line blot assays. Among 557 invasive oropharyngeal squamous cell carcinomas, 72% were positive for HPV and 62% for vaccine types HPV16 or 18. Prevalence of HPV-16/18 was lower in women (53%) than in men (66%), and lower in non-Hispanic Black patients (31%) than in other racial/ethnic groups (68%-80%). Results indicate that vaccines could prevent most oropharyngeal cancers in the United States, but their effect may vary by demographic variables. |

Sinno AK , Saraiya M , Thompson TD , Hernandez BY , Goodman MT , Steinau M , Lynch CF , Cozen W , Saber MS , Peters ES , Wilkinson EJ , Copeland G , Hopenhayn C , Watson M , Lyu C , Unger ER . Obstet Gynecol 2014 123 (4) 817-821 OBJECTIVE: To describe the human papillomavirus (HPV) genotype distribution in invasive vaginal cancers diagnosed before the introduction of the HPV vaccine and evaluate if survival differed by HPV status. METHODS: Four population-based registries and three residual tissue repositories provided formalin-fixed, paraffin embedded tissue from microscopically confirmed primary vaginal cancer cases diagnosed between 1994 and 2005 that were tested by L1 consensus polymerase chain reaction with type-specific hybridization in a central laboratory. Clinical, demographic, and all-cause survival data were assessed by HPV status. RESULTS: Sixty cases of invasive vaginal cancer were included. Human papillomavirus was detected in 75% (45) and 25% (15) were HPV-negative. HPV 16 was most frequently detected (55% [33/60]) followed by HPV 33 (18.3% [11/60]). Only one case was positive for HPV 18 (1.7%) Multiple types were detected in 15% of the cases. Vaginal cancers in women younger than 60 years were more likely to be HPV 16- or HPV 18-positive (HPV 16 and 18) than older women, 77.3% compared with 44.7% (P5.038). The median age at diagnosis was younger in the HPV 16 and 18 (59 years) group compared with other HPV-positive (68 years) and no HPV (77 years) (P5.003). The HPV distribution did not significantly vary by race or ethnicity or place of residence. The 5-year unadjusted all-cause survival was 57.4% for women with HPV-positive vaginal cancers compared with 35.7% among those with HPV-negative tumors (P5.243). CONCLUSION: Three fourths of all vaginal cancers in the United States had HPV detected, much higher than previously found, and 57% could be prevented by current HPV vaccines. |
Human papillomavirus genotype prevalence in invasive penile cancers from a registry-based United States population.
Hernandez BY , Goodman MT , Unger ER , Steinau M , Powers A , Lynch CF , Cozen W , Saber MS , Peters ES , Wilkinson EJ , Copeland G , Hopenhayn C , Huang Y , Watson M , Altekruse SF , Lyu C , Saraiya M . Front Oncol 2014 4 9 BACKGROUND: Human papillomavirus (HPV) is estimated to play an etiologic role in 40-50% of penile cancers worldwide. Estimates of HPV prevalence in U.S. penile cancer cases are limited. METHODS: HPV DNA was evaluated in tumor tissue from 79 invasive penile cancer patients diagnosed in 1998-2005 within the catchment areas of seven U.S. cancer registries. HPV was genotyped using PCR-based Linear Array and INNO-LiPA assays and compared by demographic, clinical, and pathologic characteristics and survival. Histological classification was also obtained by independent pathology review. RESULTS: HPV DNA was present in 50 of 79 (63%) of invasive penile cancer cases. Sixteen viral genotypes were detected. HPV 16, found in 46% (36/79) of all cases (72% of HPV-positive cases) was the most prevalent genotype followed equally by HPV 18, 33, and 45, each of which comprised 5% of all cases. Multiple genotypes were detected in 18% of viral positive cases. HPV prevalence did not significantly vary by age, race/ethnicity, population size of geographic region, cancer stage, histology, grade, penile subsite, or prior cancer history. Penile cases diagnosed in more recent years were more likely to be HPV-positive. Overall survival did not significantly vary by HPV status. CONCLUSION: The relatively high prevalence of HPV in our study population provides limited evidence of a more prominent and, possibly, increasing role of infection in penile carcinogenesis in the U.S. compared to other parts of the world. |
Prevalence of human papillomavirus types in invasive cervical cancers from 7 US cancer registries before vaccine introduction
Hopenhayn C , Christian A , Christian WJ , Watson M , Unger ER , Lynch CF , Peters ES , Wilkinson EJ , Huang Y , Copeland G , Cozen W , Saber MS , Goodman MT , Hernandez BY , Steinau M , Lyu C , Tucker TT , Saraiya M . J Low Genit Tract Dis 2014 18 (2) 182-9 OBJECTIVE: We conducted a baseline study of human papillomavirus (HPV) type prevalence in invasive cervical cancers (ICCs) using data from 7 cancer registries (CRs) in the United States. Cases were diagnosed between 1994 and 2005 before the implementation of the HPV vaccines. MATERIALS AND METHODS: Cancer registries from Florida, Kentucky, Louisiana, Michigan, Hawaii, Iowa, and Los Angeles, California identified eligible ICC cases and obtained sections from representative blocks of archived tumor specimens for DNA extraction. All extracts were assayed by linear array and, if inadequate or HPV negative, retested with INNO-LiPA Genotype test. Clinical and demographic factors were obtained from the CRs and merged with the HPV typing data to analyze factors associated with different types and with HPV negativity. RESULTS: A total of 777 ICCs were included in this analysis, with broad geographic, age, and race distribution. Overall, HPV was detected in 91% of cases, including 51% HPV-16, 16% HPV-18 (HPV-16-negative), and 24% other oncogenic and rare types. After HPV-16 and -18, the most common types were 45, 33, 31, 35, and 52. Older age and nonsquamous histology were associated with HPV-negative typing. CONCLUSIONS: This study provides baseline prevaccine HPV types for postvaccine ICC surveillance in the future. HPV-16 and/or -18 were found in 67% of ICCs, indicating the potential for vaccines to prevent a significant number of cervical cancers. |
Human papillomavirus prevalence in invasive anal cancers in the United States before vaccine introduction
Steinau M , Unger ER , Hernandez BY , Goodman MT , Copeland G , Hopenhayn C , Cozen W , Saber MS , Huang Y , Peters ES , Lynch CF , Wilkinson EJ , Rajeevan MS , Lyu C , Saraiya M . J Low Genit Tract Dis 2013 17 (4) 397-403 OBJECTIVE: This study aimed to conduct a representative survey of human papillomavirus (HPV) prevalence and its genotype distribution in invasive anal cancer specimens in the United States. MATERIALS AND METHODS: Population-based archival anal cancer specimens were identified from Florida, Kentucky, Louisiana, and Michigan cancer registries and Surveillance, Epidemiology, and End Results (SEER) tissue repositories in Hawaii, Iowa, and Los Angeles. Sections from 1 representative block per case were used for DNA extraction. All extracts were assayed first by linear array and retested with INNO-LiPA if inadequate or HPV negative. RESULTS: Among 146 unique invasive anal cancer cases, 93 (63.7%) were from women, and 53 (36.3%) were from men. Human papillomavirus (any type) was detected in 133 cases (91.1%) and 129 (88.4%) contained at least 1 high risk-type, most (80.1%) as a single genotype. Human papillomavirus type 16 had the highest prevalence (113 cases, 77.4%); HPV types 6, 11, 18, and 33 were also found multiple times. Among HPV-16-positive cases, 37% were identified as prototype variant Ep, and 63% were nonprototypes: 33% Em, 12% E-G131G, 5% Af1, 4% AA/NA-1, 3% E-C109G, 3% E-G131T, 2% As, and 1% Af2. No significant differences in the distributions of HPV (any), high-risk types, or HPV-16/18 were seen between sex, race, or age group. CONCLUSIONS: The establishment of prevaccine HPV prevalence in the United States is critical to the surveillance of vaccine efficacy. Almost 80% of anal cancers were positive for the vaccine types HPV-16 or HPV-18, and in 70%, these were the only types detected, suggesting that a high proportion might be preventable by current vaccines. |
Prevalence of human papillomavirus types in invasive vulvar cancers and vulvar intraepithelial neoplasia 3 in the United States before vaccine introduction
Gargano JW , Wilkinson EJ , Unger ER , Steinau M , Watson M , Huang Y , Copeland G , Cozen W , Goodman MT , Hopenhayn C , Lynch CF , Hernandez BY , Peters ES , Saber MS , Lyu CW , Sands LA , Saraiya M . J Low Genit Tract Dis 2012 16 (4) 471-9 OBJECTIVE: The study aimed to determine the baseline prevalence of human papillomavirus (HPV) types in invasive vulvar cancer (IVC) and vulvar intraepithelial neoplasia 3 (VIN 3) cases using data from 7 US cancer registries. MATERIALS AND METHODS: Registries identified eligible cases diagnosed in 1994 to 2005 and requested pathology laboratories to prepare 1 representative block for HPV testing on those selected. Hematoxylin-eosin-stained sections preceding and following those used for extraction were reviewed to confirm representation. Human papillomavirus was detected using L1 consensus polymerase chain reaction (PCR) with PGMY9/11 primers and type-specific hybridization, with retesting of samples with negative and inadequate results with SPF10 primers. For IVC, the confirmatory hematoxylin-eosin slides were re-evaluated to determine histological type. Descriptive analyses were performed to examine distributions of HPV by histology and other factors. RESULTS: Human papillomavirus was detected in 121/176 (68.8%) cases of IVC and 66/68 (97.1%) cases of VIN 3 (p < .0001). Patients with IVC and VIN 3 differed by median age (70 vs 55 y, p = .003). Human papillomavirus 16 was present in 48.6% of IVC cases and 80.9% of VIN 3 cases; other high-risk HPV was present in 19.2% of IVC cases and 13.2% of VIN 3 cases. Prevalence of HPV differed by squamous cell carcinoma histological subtype (p < .0001) as follows: keratinizing, 49.1% (n = 55); nonkeratinizing, 85.7% (n = 14), basaloid, 92.3% (n = 14), warty 78.2% (n = 55), and mixed warty/basaloid, 100% (n = 7). CONCLUSIONS: Nearly all cases of VIN 3 and two thirds of IVC cases were positive for high-risk HPV. Prevalence of HPV ranged from 49.1% to 100% across squamous cell carcinoma histological subtypes. Given the high prevalence of HPV in IVC and VIN 3 cases, prophylactic vaccines have the potential to decrease the incidence of vulvar neoplasia. |
