BACKGROUND: The increasing incidence of oropharyngeal squamous cell cancer (OPSCC) is well established. However, up-to-date incidence estimates and trends for head and neck squamous cell cancers (HNSCCs) overall, including major anatomic sites, and nonoropharyngeal (non-OP) HNSCCs by sex, race, and age in the United States are not well described. METHODS: A retrospective analysis of incident HNSCCs during 1992 through 2014 using the Surveillance, Epidemiology, and End Results database was performed to evaluate the incidence of HNSCCs overall, OPSCC, and non-OP HNSCC (those of the larynx, oral cavity, hypopharynx, nasopharynx, and nasal cavity)...

BACKGROUND: Human papillomavirus (HPV)-driven oropharyngeal squamous cell carcinoma (OPSCC) represents a distinct tumour entity in comparison to HPV-negative OPSCC. The clinical, radiological, morphological features and distribution of HPV E6/E7 mRNA were investigated in resected specimens of OPSCC. METHODS: We retrieved formalin-fixed, paraffin-embedded whole section slides from 24 p16/HPV-DNA positive and 18 p16/HPV-DNA negative primary tumours and 16 corresponding metastases in patients with early-stage OPSCC who underwent planned curative or diagnostic primary transoral robotic surgery...

OBJECTIVES: Human papillomavirus-negative oropharyngeal squamous cell carcinoma (OPSCC) has unfavorable survival outcomes. Two outcomes have been identified based on smoking history and tumor stage. We investigate the prognostic role of pre-treatment positron emission tomography (PET) in high-risk OPSCC. MATERIALS AND METHODS: We enrolled 147 M0 OPSCC patients with p16-negative staining and a history of heavy smoking (>10 pack-years) or T4 disease. All patients completed primary chemoradiotherapy, and 42% maximum standard uptake values (SUVmax ) were used as the threshold for primary tumor...

OBJECTIVE: The addition of induction chemotherapy (ICT) to concurrent chemoradiation (CCRT) has been investigated as a method of improving outcomes among patients with locally advanced head and neck squamous cell carcinoma. Previous studies have consisted of heterogeneous populations with both p16-positive and p16-negative disease and varying extent of nodal disease burden. We evaluated the role of ICT in p16-positive oropharyngeal squamous cell carcinoma (OPSCC) at high-risk of distant failure...

BACKGROUND: Human papillomavirus (HPV) prevalence in oropharynx squamous cell carcinoma (OPSCC) is on the rise. HPV-linked OPSCCs represent a distinct clinical entity with a better treatment response and patient survival compared to tumors not linked to HPV. An emerging role in treatment response has been attributed to immune cell infiltration in human tumors. In this study, we investigated immune cell infiltration in human SCC of the head and neck region and its relation to overall survival after treatment with surgery (with or without radiotherapy) or concomitant chemo (or cetuximab)-radiotherapy...

Based on clinical and experimental data, oropharyngeal squamous cell carcinomas (OPSCC) associated with human papillomavirus (HPV) have been recognized as a distinct entity of head and neck cancers. However, outside of clinical trials, HPV status currently has no impact on treatment. The natural replication cycle of HPV takes place in epithelial cells, and is thus spatially separated from cytotoxic immune cells in the epidermis. Dendritic cells (Langerhans cells, LC), however, are frequent in this upper dermal layer...

OBJECTIVES: HPV positive oropharyngeal cancer (OPSCC) is biologically and clinically different from HPV negative OPSCC. Here, we evaluate the use of a radiomic approach to identify the HPV status of OPSCC. METHODS: Four independent cohorts, totaling 778 OPSCC patients with HPV determined by p16 were collected. We randomly assigned 80% of all data for model training (N=628) and 20% for validation (N=150). On the pre-treatment CT images, 902 radiomic features were calculated from the gross tumor volume (GTV)...

PURPOSE: Human papillomavirus (HPV)- induced oropharyngeal squamous cell carcinoma (OPSCC) is still increasing worldwide. We aimed to investigate if the HPV-prevalence of OPSCC in the Netherlands is rising as well, especially in female patients. In addition, we evaluated the association between HPV-positive OPSCC and suspicious Pap results of the cervix in these female patients. PATIENTS AND METHODS: Patients with OPSCC treated in the period 2000-2015 at the VU University Medical Center Amsterdam, were included (n=926)...

We explored potential associations of the PD-1/PD-L1/PD-L2 pathway with clinical characteristics, outcome, and expression of EGFR, HER2, HER3 in oropharyngeal squamous cell carcinoma (OPSCC) using an institutional database. Protein expression was assessed by immunohistochemistry on tissue microarray sections (EGFR, HER2, HER3) or whole tissue sections (PD-1/PD-L1/PD-L2). Expression of EGFR, HER2, HER3, PD-L1, and PD-L2 was quantified on tumor cells. Maximum density of PD-1 positive lymphocytes was measured on a scale of 0-4 within the tumor mass and peritumoral stroma...

Background: Oropharyngeal squamous cell carcinomas (OPSCCs) are traditionally caused by smoking and excessive alcohol consumption. However, in the last decades high-risk human papillomavirus (HR-HPV) infections play an increasingly important role in tumorigenesis. HPV-driven OPSCCs are known to have a more favorable prognosis, which has led to important and marked changes in the recently released TNM-8. In this edition, OPSCCs are divided based on p16-immunostaining, with p16-overexpression as surrogate marker for the presence of HPV...

BACKGROUND: Oropharyngeal Squamous Cell Carcinoma (OPSCC) is increasing in incidence despite a decline in traditional risk factors. Human Papilloma Virus (HPV), specifically subtypes 16, 18, 31 and 35, has been implicated as the high-risk etiologic agent. HPV positive cancers have a significantly better prognosis than HPV negative cancers of comparable stage, and may benefit from different treatment regimens. Currently, HPV related carcinogenesis is established indirectly through Immunohistochemistry (IHC) staining for p16, a tumour suppressor gene, or polymerase chain reaction (PCR) that directly tests for HPV DNA in biopsied tissue...

Toll-like receptors (TLRs) have been widely investigated due to their importance in the inflammatory response and possible links to tumor promotion/regression and prognosis. In cancers with an infective etiology, such as human papillomavirus (HPV)-associated Oropharyngeal Squamous Cell Carcinoma (OPSCC), TLR responses may be activated and play a role in tumorigenesis. Our aim was to assess the expression of all TLRs in OPSCC cell lines (both HPV+ and HPV-) by qPCR, Western Blot and flow cytometry and assess their response to TLR ligands lipopolysaccharide (LPS), LPS ultra-pure (LPS-UP) and peptidoglycan (PGN) by analyzing IL-8 and IL-6 production...

Incidence of oropharyngeal carcinoma (OPSCC) is increasing significantly worldwide. Due to its association with chronic tobacco/alcohol consumption, but increasingly also with the human papillomavirus HPV-16, oropharyngeal carcinoma is a genetically heterogeneous tumor group with high prognostic diversification. HPV-associated OPSCC respond significantly better to previous treatment concepts than non-HPV-associated. Both after primary surgical as well as after radiotherapie, radiochemotherapie and anti-EGFR treatment, this tumor group shows a significantly better survival...

Human papilloma virus-positive oropharyngeal squamous cell carcinoma (HPV+ OPSCC) represents a distinct subgroup of head and neck cancers associated with clinical outcomes that are not accurately categorized by existing tumor-node-metastasis-based staging methods. Given the significant impact of immune parameters, such as tumor-infiltrating lymphocytes (TIL) in many cancers, we sought to determine if immunophenotyping tumors can improve categorization of HPV+ OPSCCs for prognostic purposes. In a cohort of 190 patients with HPV+ OPSCC, we quantified and determined the localization of CD8+ TILs, as well as PD-L1-expressing tumor cells (TC) and immune cells (IC)...

OBJECTIVES: Diffusion weighted imaging (DWI) is a frequently performed MRI sequence in cancer patients. While previous studies have shown the clinical value of the apparent diffusion coefficient (ADC) for response prediction and response monitoring, less is known about the biological background of ADC. In the tumor microenvironment, hypoxia and increased proliferation of tumor cells contribute to resistance to (radio-)therapy, while high T-cell influx is related to better prognosis. We investigated the correlation between these three tissue characteristics and ADC in 20 oropharyngeal squamous cell carcinoma patients...
