Importance: Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) has a favorable prognosis, and p16 immunohistochemistry is a surrogate marker of high-risk HPV infection and strong prognosticator. Given this favorable prognosis, treatment de-escalation for p16-positive OPSCC is now being considered with the goal of decreasing treatment-associated morbidity without compromising tumor control. The role of adjuvant chemotherapy in this setting is becoming increasingly unclear...

OBJECTIVES: Human papillomavirus (HPV) has emerged as a driving cause of head and neck cancer, but investigations outside the West are limited. A p16 immunohistochemistry is a commonly used biomarker for HPV cancers. We sought to investigate the pathology and rates of HPV head and neck oropharyngeal cancer in Japan via p16 immunohistochemistry at 2 institutions in Japan. METHODS: Fifty-nine oropharyngeal specimens from 2 university hospitals in Japan were examined for morphology and p16 immunohistochemistry...

Infections with human papillomavirus (HPV) are common and transmitted by direct contact. Although the great majority of infections resolve within 2 years, 13 phylogenetically related, sexually transmitted HPV genotypes, notably HPV16, cause - if not controlled immunologically or by screening - virtually all cervical cancers worldwide, a large fraction of other anogenital cancers and an increasing proportion of oropharyngeal cancers. The carcinogenicity of these HPV types results primarily from the activity of the oncoproteins E6 and E7, which impair growth regulatory pathways...

OBJECTIVES/HYPOTHESIS: HPV-positive oropharyngeal squamous cell carcinoma has a more favorable prognosis when compared to HPV-negative disease, regardless of the presence of nodal metastases. However, the importance of contralateral neck treatment based on HPV status has not been well studied. Given the historically poor prognostic implications of cervical nodal metastases, this study sought to elucidate the relationship between HPV status and contralateral/bilateral nodal metastasis in patients with oropharyngeal squamous cell carcinoma...

BACKGROUND: Few studies have addressed how human papilloma virus (HPV) infection in oropharyngeal squamous cell carcinoma (OPSCC) affects the outcome of surgical therapy; furthermore, the relationship between the presence of HPV DNA and neck lymph node (LN) metastasis has not been well established. METHODS: A total of 65 patients who underwent surgery as a first-line therapy for OPSCC were enrolled in this study. In HPV-positive patients, the presence of HPV DNA in metastatic neck LN lesions was evaluated...

BACKGROUND: Human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (SCC) has a better outcome than most head neck squamous cell carcinomas (HNSCCs) and an HPV-positive lymph node metastasis likely has an HPV-positive oropharyngeal SCC origin. Determining HPV-status in cervical lymph nodes by fine-needle aspiration cytology (FNAC) may be useful for diagnosis. METHODS: FNACs from 66 patients with neck masses were prospectively examined for HPV DNA and HPV16 mRNA by a polymerase chain reaction (PCR)-based assay, and the data correlated to diagnosis and HPV-status obtained from histopathological specimens...

BACKGROUND: Human papillomavirus (HPV) is a critical element in the rising incidence of oropharyngeal squamous cell carcinoma (OPSCC), although whether this trend will continue, and the types of HPV responsible, are currently unknown. We previously demonstrated an increased incidence of HPV-related OPSCC in the high HPV prevalence area of Eastern Denmark from 2000 to 2010. Therefore, we investigated if the incidence for OPSCC continued to rise, the association to HPV and putative HPV-types in Eastern Denmark from 2011 to 14...

Oral cavity cancer (OC) has steadily decreased in the United States (US) since 1973 whereas oropharyngeal cancer (OP) has increased. We analyzed OC and OP cases from the Oklahoma Central Cancer Registry and Surveillance, Epidemiology, and End Results program comparing those diagnosed from 1997-1999 to those diagnosed from 2010-2012. We compared the incidence of OC and OP cases between Oklahoma and the US and by demographic factors. We observed an increase in OP cases, but no change in OC cases in both the US and in Oklahoma, and observed some differences between Oklahoma and the US by race, gender, and age group...

Human papilloma virus (HPV)-associated head and neck cancer (HNC) has generated significant amount of research interest in recent times with focus shifted to oral cavity squamous cell cancer (OCSCC) after oropharyngeal cancer. Due to high incidence of OCSCC and anecdotal reports on association of HPV infection from northern region of India, this study was conceived to investigate HPV infection and establish its association with lifestyle habits such as tobacco, alcohol consumption, oro-genital sex, number of sexual contacts, and change in quality of life posttreatment...

PurposeThere is a paucity of biomarkers to predict failure in human papilloma-virus positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC) following curative therapy. E6/E7 viral oncoproteins are constitutively expressed in HPV+ tumors and highly immunogenic, resulting in readily detected serum antibodies. The purpose of this study is to determine if serum E6 and E7 antibody levels can potentially serve as a biomarker of recurrence in patients with HPV+OPSCC. Experimental DesignWe evaluated E6/E7 antibody levels in patients with previously untreated, advanced stage(III, IVa-b), HPV+OPSCC receiving definitive chemoradiation under a uniform protocol from 2003-2010...

Extracapsular spread (ECS) is one of the most important prognostic factors in head and neck squamous cell carcinoma (HNSCC). However, despite its major clinical relevance, there are still a number of important remaining issues regarding this condition. Indeed, standardized diagnostic and grading criteria of ECS are still lacking. The imaging modality of choice for its diagnosis is a matter of debate. Current research looking at the identification of specific biomarkers is ongoing. Recent findings demonstrate a direct correlation between the level of extension of ECS and a poor prognosis...

OBJECTIVES: To explore whether HPV-related biomarkers predict oropharyngeal squamous cell cancer (OPSCC) survival similarly across different global regions, and to explore their prognostic utility among non-oropharyngeal (non-OP) head and neck cancers. METHODS: Data from 1362 head and neck SCC (HNSCC) diagnosed 2002-2011 was used from epidemiologic studies in: Brazil (GENCAPO study, n=388), U.S. (CHANCE study, n=472), and Europe (ARCAGE study, n=502). Tumors were centrally tested for p16(INK4a) and HPV16 DNA (by PCR)...

OBJECTIVE: The rapid worldwide rise in incidence of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) has generated studies confirming this disease as an entity distinct from traditional OPSCC. Based on pathology, surgical studies have revealed prognosticators specific to HPV-positive OPSCC. The current AJCC/UICC staging and pathologic nodal (pN)-classification do not differentiate for survival, demonstrating the need for new, HPV-specific OPSCC staging...

BACKGROUND: Accurate identification of HPV-driven oropharyngeal cancer (OPC) is a major issue and none of the current diagnostic approaches is ideal. An in situ hybridization (ISH) assay that detects high-risk HPV E6/E7 mRNA, called the RNAscope HPV-test, has been recently developed. Studies have suggested that this assay may become a standard to define HPV-status. METHODS: To further assess this test, we compared its performance against the strategies that are used in routine clinical practice: p16 immunohistochemistry (IHC) as a single test and algorithms combining p16-IHC with HPV-DNA identification by PCR (algorithm-1) or ISH (algorithm-2)...

OBJECTIVES: Head and neck squamous cell carcinomas (HNSCCs) exhibit great biological heterogeneity and relatively poor prognosis. Tobacco and alcohol consumption is involved in the cause of the majority of these cancers, but over the last several years, Human Papilloma Virus (HPV) infection has increased specifically in oropharyngeal cancers and become an additional risk factor. Here, we evaluated the number of Langerhans cells (LCs) in HNSCC and reporting its prognostic power in comparison to other risk factors...

It is universally accepted that high-risk human papillomavirus (HR-HPV) is the cause of cervical dysplasia and cancer. More recently it has been shown that HPV is also a marker of clinical outcome in oropharyngeal cancer. However, contemporary information is lacking on both the prevalence of HPV infection in vulvar cancer (VSCC), its precursor lesion, vulvar intraepithelial neoplasia (VIN) and the influence of HPV-status on the prognosis of this malignancy. We have conducted a detailed population-based study to examine rates of progression of VIN to VSCC, type-specific HPV prevalence in vulvar disease and the influence of HPV status on clinical outcome in VSCC...
