BACKGROUND: Treatment for oropharyngeal squamous cell carcinoma (OPSCC) has changed, as the proportion of human papilloma virus (HPV)-related disease has increased. We evaluated nationwide information on its management and outcome during the treatment paradigm change period. METHODS: We included all patients diagnosed and treated for OPSCC at the five Finnish university hospitals from 2000 to 2009. Patient records and pathology registries provided the clinicopathological data...

AIMS: We recently reported that a small subset (7%) of oesophageal squamous cell carcinomas completely lacking SOX2 expression had unique clinicopathological features and a dismal prognosis. The present study aimed to elucidate whether the findings obtained in oesophageal cancers are applicable to hypopharyngeal or oropharyngeal squamous cell carcinomas (HPSCCs or OPSCCs, respectively). METHODS AND RESULTS: The study cohort consisted of consecutive patients with HPSCC (n=130) and OPSCC (n=65) who underwent surgery without preoperative therapy...

PURPOSE: The purpose of this study was to determine if the use of the FIREFLY imaging system could be an asset in transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC). The system uses indocyanine green dye (ICG), which fluoresces when illuminated by near-infrared light from the Da Vinci robot. The system may improve visualization of tumor margins, highlight important vascular structures, and help identify the location of tumors and unknown primary head and neck cancers...

Human papillomavirus-associated oropharyngeal squamous cell carcinoma (HPV-OPSCC) comprises approximately 25% of all head and neck cancers (head and neck squamous cell carcinoma, HNSCC). Epidemiologic studies have shown a dramatic increase of HPV-OPSCC in the past 2 decades, whereas tobacco-related HNSCC rates are decreasing worldwide. The distinctions between HPV-OPSCC and oral cavity cancers are now reflected in the most recent editions of the World Health Organization Classification of Tumors of the Head and Neck and the American Joint Committee on Cancer Staging Manual, respectively...

Nuzhat Husain, Azfar Neyaz
High-risk human papillomavirus (HR-HPV) is a causative agent for an increasing subset of oropharyngeal squamous cell carcinoma. HPV 16 accounts for 90% of cases. The chance for malignant transformation due to infection with high-risk HPV is proportional to the expression of the viral oncogene products E6 and E7, which inactivate p53 and retinoblastoma (Rb) tumor suppressor functions. P16 is a surrogate marker of HPV associated HNSCC and 2+/3+ expression in more than 75% cells is diagnostic. Molecular demonstration of integrated virus by in situ hybridization is specific but has low sensitivity...

ANO1 is a calcium-activated chloride channel that is frequently overexpressed in head and neck squamous cell carcinoma (HNSCC) and other cancers. While ANO1 expression negatively correlates with survival in several cancers, its epigenetic regulation is poorly understood. We analyzed HNSCC samples from TCGA and a separate dataset of HPV+ oropharyngeal squamous cell carcinoma (OPSCC) samples to identify differentially methylated regions. E6 and E7 transfected normal oral keratinocytes (NOK) were used to induce hypermethylation of the ANO1 promoter...

In vitro head and neck cancer studies have demonstrated that epidermal growth factor receptor kinase substrate 8 (Eps8) overexpression contributes to squamous carcinogenesis. Oral squamous cell carcinoma studies have correlated Eps8 expression with metastatic disease and poor prognosis. Head and neck squamous cell carcinoma (HNSCC) studies comparing its expression by anatomic site or in in vivo regional metastases have not been performed. In this study, we compared Eps8 expression in HNSCCs arising in the oral cavity (OCSCC) and oropharynx (OPSCC) along with their corresponding regional lymph nodes (LNs) metastases...

OBJECTIVES: To determine differences in oropharyngeal squamous cell carcinoma (OPSCC) incidence between 1975 and 2014 stratified by race, sex, and age. MATERIALS AND METHODS: We obtained age-adjusted OPSCC incidence rates for race and sex groups from 1975 to 2014 using the Surveillance, Epidemiology, and End Results 9 database. We defined OPSCC as cancers of the base of tongue, lingual/palatine tonsil, oropharynx, soft palate, uvula, and Waldeyer's ring. We used Joinpoint analyses to determine incidence trends for race/sex/age groupings...

INTRODUCTION: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing, but data on the incidence of synchronous, bilateral tonsillar squamous cell carcinomas (BiTSCCs) is sparse. In this study, we report the incidence and tumour characteristics of BiTSCCs in a population-based, consecutive cohort of OPSCCs. METHODS: We identified all patients diagnosed with tonsillar squamous cell carcinoma (TSCC) in eastern Denmark during a 15-year period to detect the incidence of synchronous BiTSCCs...

Importance: Recently, the American Joint Committee on Cancer (AJCC) updated its staging system for human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC). The prognostic significance of perineural invasion (PNI) and angiolymphatic invasion (ALI) within this staging system is unknown. Objective: To examine the prevalence and prognostic significance of PNI and ALI in HPV-positive OPSCC. Design, Setting, and Participants: A retrospective review was performed of all patients with HPV-positive OPSCC treated surgically at the University of Pittsburgh Medical Center from January 1, 1980, through December 31, 2015, with at least 1 year of follow-up or death within 1 year...

Importance: In recent years, transoral robotic surgery (TORS) has emerged as a useful treatment for oropharyngeal squamous cell carcinoma (OPSCC). In appropriately selected patients, the use of TORS may allow avoidance of adjuvant chemotherapy and/or radiotherapy, thereby avoiding the long-term adverse effects of these therapies. Objective: To compare functional speech, swallowing, and quality-of-life outcomes longitudinally between those undergoing TORS only and those undergoing TORS and adjuvant radiotherapy (TORS+RT) or TORS and chemoradiotherapy (TORS+CRT)...

PURPOSE: To investigate survival outcomes of patients treated with concurrent cetuximab and radiotherapy for primary management of both HPV positive and negative OPSCC, and compare the results to traditional platinum-based therapy. We hypothesize that the use of cetuximab in the HPV positive OPSCC patients will result in inferior survival based on tumor biological differences. STUDY DESIGN: A single institution retrospective analysis of 304 patients. The primary outcomes of interest were 1) overall survival and 2) relapse free survival...

PURPOSE: Human papilloma virus (HPV)-associated oropharyngeal squamous cell cancer (OPSCC) has a much better prognosis than HPV-negative OPSCC and this is linked to dense tumor immune infiltration. Since the viral antigens may trigger potent immunity, we studied the relationship between the presence of intratumoral HPV-specific T-cell responses, the immune contexture in tumor microenvironment and clinical outcome. EXPERIMENTAL DESIGN: To this purpose an in-depth analysis of tumor-infiltrating immune cells in a prospective cohort of 97 HPV16-positive and -negative OPSCC patients was performed using functional T-cell assays, mass cytometry (CyTOF), flow cytometry and fluorescent immunostaining of tumor tissues...
