Head and neck cancer is worldwide the sixth most common cancer. Prognosis is linked to tumour (primary tumours, nodal stage and distant metastasis) and general patients' characteristics. Currently, the TNM-staging system is the most used staging system in the world. Beside this TNM-staging system, other prognostic factors are used to select the best treatment for each individual patient. This article is protected by copyright. All rights reserved.

BACKGROUND: The TNM (tumor, nodes, metastasis) classification is updated periodically according to the literature and international recommendations. With the 8th edition, notable changes have been developed especially with regard to oropharyngeal cancer. MATERIALS AND METHODS: The modifications as well as the practicability of the classification for staging of oropharyngeal cancers are demonstrated on the basis of cases from the tumor database. RESULTS: The latest edition of the TNM classification realizes requirements to differentiate between human papilloma virus (HPV) positive and HPV-negative tumors during staging...

AIMS: The distinct difference in disease phenotype of human papillomavirus-positive (HPV+) and -negative (HPV-) oropharyngeal squamous cell cancer (OPSCC) patients might also be apparent when assessing the effect of time to treatment initiation (TTI). We assessed the overall survival and progression-free survival (PFS) effect from increasing TTI for HPV+ and HPV- OPSCC patients. MATERIALS AND METHODS: We examined patients who received curative-intended therapy for OPSCC in eastern Denmark between 2000 and 2014...

PURPOSE: Distant metastasis (DM) is the main cause of death for patients with human papillomavirus (HPV)-related oropharyngeal cancers (OPCs); yet, there are few reliable predictors of DM in this disease. The role of quantitative imaging (ie, radiomic) analysis was examined to determine whether there are primary tumor features discernible on imaging studies that are associated with a higher risk of DM developing. METHODS AND MATERIALS: Radiation therapy planning computed tomography scans were retrieved for all nonmetastatic p16-positive OPC patients treated with radiation therapy or chemoradiation therapy at a single institution between 2005 and 2010...

Renal cell carcinoma (RCC) is a common malignancy with high metastatic potential, primarily due to its extensive vascularity. Common sites of metastasis include lungs, bone, lymph nodes, liver, and brain. However, rare cases of metastasis to other sites including inguinal lymph nodes, peritoneum/mesentery, and orbit have been published in the literature. Herein, a unique case involving metastasis of RCC to the uvula is presented. The patient is a 55-year-old White female with a past medical history of stage 3 (T3aN0M0) RCC s/p nephrectomy 3 years prior to presentation...

Head and neck squamous cell carcinomas (HNSCCs) arise in the mucosal linings of the upper aerodigestive tract and are unexpectedly heterogeneous in nature. Classical risk factors are smoking and excessive alcohol consumption, and in recent years, the role of human papillomavirus (HPV) has emerged, particularly in oropharyngeal tumours. HPV-induced oropharyngeal tumours are considered a separate disease entity, which recently has manifested in an adapted prognostic staging system while the results of de-intensified treatment trials are awaited...

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...

OBJECTIVES: As longer times from the first symptom to diagnosis and treatment of oral cancers have been linked to poorer outcomes, this study investigates the contribution of the specialist to this time (STI). SUBJECTS AND METHODS: A series of 228 oral/oropharyngeal squamous cell carcinoma patients were retrospectively studied to determine the STI and its related factors. RESULTS: Patients were mostly males (n = 170; 74.5%), (50.7% stages I-II), mean age = 61...

PURPOSE OF REVIEW: Oropharyngeal cancer (OPC) incidence is increasing worldwide, especially in developed countries where it seems to be etiologically related to the elevating rates of high-risk human papillomavirus (HPV) infection. Considered a distinct disease because of its weak correlation with the traditional risk factors (tobacco use and alcohol), it has different patterns of survival outcomes, locoregional and distant failure, generally with better prognosis independently of the treatment...

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...
