The Union for International Cancer Control (UICC) published in 2017 a revised 8th edition of the TNM classification bringing numerous changes in the classification of head and neck tumors. Three new entities were introduced, namely HPV-positive oropharyngeal carcinoma, neck metastasis from an unknown primary, and skin carcinoma of the head and neck. Going beyond the traditional size of the lesions, several new predictive factors have been included, such as the depth of invasion of oral carcinoma and the extracapsular spread of neck metastasis...

OBJECTIVE: Lymph node yield in therapeutic neck dissection is clinically significant and incompletely studied. We quantified node yield based on extent of neck dissection and presence of preoperative radiation. We also evaluated factors affecting incidence of extracapsular spread (ECS). METHODS: Retrospective review of 499 patients undergoing therapeutic neck dissection; 414 patients met inclusion criteria and were divided into 2 groups: neck dissection alone or before radiation (surgery first: 280 patients; 385 dissections) and primary radiation before surgery (radiation first: 134 patients; 157 dissections)...

Deregulated expression of SOX11 has been shown to be involved in the progression of various types of cancer. However, the role of SOX11 in head and neck cancer remains largely unknown. In this study, coimmunoprecipitation (Co-IP) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were performed to identify the proteins that bind to SOX11 at significantly higher levels in head and neck cancer cells than in normal human oral keratinocytes. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses indicated that many potential SOX11-binding partners were associated with protein synthesis, cell metabolism, and cell-cell adhesion...

Extrahepatic bile duct carcinoma is a potentially malignant gastrointestinal lesion. Cancer cells spread via the lymphatic system to regional lymph nodes and help in tumor progression. However, there are no reports on the prognostic impact of extracapsular lymph node invasion and myofibroblastic activity in this cancer. Hence, we classified the histopathologic patterns of lymph nodes into 2 patterns: extracapsular lymph node invasion or not. Based on this, we investigated 32 cases of extrahepatic bile duct cancer with lymph node metastasis and classified 21 cases as positive and 11 cases as negative...

BACKGROUND: Several reports have suggested that selected patients with human papillomavirus-related oropharyngeal cancer can be managed with surgery alone. We retrospectively reviewed tonsillar cancer cases to analyze treatment de-intensification after transoral resection. METHODS: Eighteen patients with tonsillar cancer who had undergone transoral resection were included. The patients' characteristics, p16 status, adverse features, clinical course, overall survival, and relapse-free survival according to p16 status were retrospectively examined...

Skip metastasis (SM) in Well Differentiated Thyroid Cancer (WDTC) patients are lateral neck lymph node metastasis that have skipped the central neck compartment. In these patients, prophylactic central neck dissection remains controversial. We sought to identify clinicopathological factors associated with SM and determine the accuracy of central neck metastasis imaging in 68 patients at our institution over 16 years. 12 patients (17.6%) had SMs. Compared to the patients with occult central neck metastases, those with SM were more likely to have T1 tumors (p=0...

OBJECTIVES: Log odds of positive lymph nodes (LODDS) has been demonstrated as a very promising staging model for multiple cancer sites, as it avoids singularity and predicts prognosis significantly better than conventional nodal staging and lymph node ratio. However, published studies on the influence of LODDS for patients with OSCC are very seldom. MATERIAL AND METHODS: Retrospective chart review of 499 patients with treatment-naive oral squamous cell carcinoma...

The lymph node ratio(LNR) has been described as a novel predictor of the survival of patients with oral and oropharyngeal squamous cell carcinoma(O/OPSCC). The purpose of this study was to evaluate whether LNR is better at predicting survival and the need for adjuvant treatment than traditional tumour-nodal-metastasis(TNM) staging. Eight hundred nine patients with O/OPSCC and positive lymph node disease were retrospectively enrolled in this study. LNR equal to 0.075 is the best cut-off value for stratifying 5-year disease-free survival(DFS)...

INTRODUCTION: Recent evidence suggests that the local renin-angiotensin system has been implicated in various malignancies. The mitochondrial assembly receptor is a newly identified receptor for angiotensin peptides, angiotensin-(1-7), and has an important role in the renin-angiotensin system. However, the role of the mitochondrial assembly receptor in the prognosis of cancer patients remains unclear. The aim of this study was to evaluate the significance of mitochondrial assembly receptor signaling in the prognosis of oral tongue squamous cell carcinoma...

PURPOSE: Keratinization is a routinely reported histologic feature in head and neck cancer. In contrast to numerous clinicopathologic parameters, the prognostic value of keratinization in oral squamous cell carcinoma (OSCC) is rarely reported in the literature. The purpose of this study was to review the outcome of patients with OSCC with a special focus on the degree of keratinization. PATIENTS AND METHODS: In this retrospective cohort study, we evaluated the medical records at the Department of Oral and Maxillofacial Surgery, Jena University Hospital, and investigated the outcome of patients with OSCC with disease-free survival and disease-specific survival according to the degree of keratinization...

OBJECTIVES: Lymph node ratio (LNR) is an established predictor in different entities of carcinoma, including head and neck malignancies. In oropharyngeal squamous cell carcinoma (OPSCC), lymph node involvement differs between Human Papilloma Virus (HPV)-positive and negative tumours. Herein, we evaluate the impact of HPV association on the concept of LNR. METHODS: 88 surgically treated patients were included in this retrospective chart review. HPV-positive and negative OPSCC were evaluated for prediction of outcome by LNR separately...
