Survival periods of patients following surgical therapy of oral squamous cell carcinoma (OSCC) have previously been demonstrated to decrease over recent decades. Epidermal growth factor receptor (EGFR) and Cortactin are molecular markers that are important in tumour progression and development, and interact within the EGF pathway. Although EGFR antibody therapy exists, sufficient efforts for increased survival are still lacking due to the present limited response rates. The aim of the present study was to examine the association between EGFR and Cortactin expression on survival rates of OSCC patients and to determine whether EGFR and Cortactin expression levels are associated with advanced tumor sizes and lymphnode-metastases...

Ultrasonography is the first choice of lymph node metastasis (LNM) detection which is crucial for therapeutic options of papillary thyroid cancer (PTC). However, the sensitivity of ultrasonography in detecting LNM of PTC is relatively low; especially in central LNM. MiR-324-5p has been reported to play important roles in the metastasis of various cancers. To explore the relationship between miR-324-5p and LNM in PTC, quantitative real-time polymerase chain reaction was performed in PTC tissue and fine needle aspiration (FNA) washout successively...

OBJECTIVES: Subgroup analysis from two randomized trials showed a survival benefit for adjuvant chemoradiation (CRT) over radiation alone (RT) in patients with extracapsular spread (ECS) of involved lymph nodes and/or positive margins (PM) in resected head and neck cancer (HNSCC). However, results were not analyzed separately for patients with ECS or PM and were not stratified by tumor subsite/HPV status. We therefore sought to determine whether adjuvant CRT is associated with a survival benefit, separately among patients with ECS or PM and stratified by subsite/HPV status...

Subungual melanoma, an uncommon form of acral melanoma that arises within the nail matrix, accounts for 1%-3% of all cutaneous melanoma in Caucasians. As subungual melanoma presents in a more disguised manner than cutaneous lesions, increased vigilance is required. It most commonly presents as a discolouration of the nail, nail splitting or nail-bed bleeding. Black pigmentation of the adjacent nail fold, termed Hutchinson's sign, may be a diagnostic clue. Treatment of subungual melanoma remains surgical with wide local excision and amputation primary modalities...

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...

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...
