BACKGROUND: In epithelial-to-mesenchymal transition, epithelial cells lose their features, acquiring a mesenchymal-like phenotype. Nm23-H1 protein relates to tumor cells' metastatic potential, its low expression in carcinomas often meaning a poor prognosis. This study newly investigated the role of nuclear nm23-H1 in laryngeal squamous cell carcinoma epithelial-to-mesenchymal transition. METHODS: Immunohistochemical analyses of nuclear nm23-H1, E-cadherin, N-cadherin, Snail, Zinc finger E-box binding homeobox (ZEB)1, and ZEB2 were performed in 33 consecutive patients with laryngeal SCC...

BACKGROUND: With the introduction of new American Joint Committee on Cancer (AJCC) classifications for head and neck cancers few cases are upgraded from T2 to T3 based only on depth of invasion. The role of adjuvant therapy in this particular subset of patients is still not defined. METHODS: This is a retrospective analysis of data from 2009 to 2015, of patients with histopathology of pT1, T2, and N0. A total of 375 patients were subdivided into 3 groups per the new AJCC classification depth of invasion <5 mm, 6 to 10 mm, and >10 mm...

It is traditionally accepted that subglottic carcinoma has a worse prognosis than tumors arising in other subsites of the larynx, owing to its tendency to present in advanced stages, with a high incidence of cartilage invasion and extralaryngeal spread. The incidence of subglottic carcinoma varies among series, mainly because there is no uniform definition of the upper boundary of the subglottis. The extent of the tumor may be difficult to define because subglottic carcinoma may spread through the submucosa without visible mucosal changes...

BACKGROUND: Precise imaging of nerves have been challenging in the head and neck region, mainly due to low spatial resolution. Here, we investigated how nerves in the head and neck region could be visualized using an ultra-high magnetic field MR system. METHODS: We used formol-carbol-fixed human cadaveric necks and obtained MR diffusion tensor images (DTIs) using a 9.4 Tesla (T) ultra-high magnetic field MR system. Afterward, we prepared tissue sections and checked the anatomic relationships between the neurons and the carotid artery in order to confirm that the visualized fibers are indeed neuron fibers...

The newly introduced pathologic diagnosis of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) will result in less bilateral thyroid surgery as well as deescalation in T4 suppressive and radioactive iodine treatment. Although, NIFTP is a nonmalignant lesion that has nuclear features of some papillary malignancies, the challenge for the surgeon is to identify a lesion as possibly NIFTP before the pathologic diagnosis. NIFTP, due to its reduction of overall rates of malignancy, will result in the initial surgical pendulum swinging toward lobectomy instead of initial total thyroidectomy...

BACKGROUND: Surveillance, Epidemiology, and End Results Cancer Registries (SEER) began collecting human papillomavirus (HPV) status for upper aerodigestive tract cancers in 2010. However, classification of p16-testing was not included in the Collaborative Stage coding guidelines, potentially leading to inconsistent coding. METHODS: The HPV values for Iowa patients with oropharyngeal cancers (n = 824) were recoded based on modified guidelines that included p16 test results, and compared with the original guidelines...
