BACKGROUND: Chemokines and chemokine receptors are critical in oral tumourigenesis. The atypical chemokine receptor ACKR2 is a scavenger of CC chemokines controlling the availability of these molecules at tumour sites, but the role of ACKR2 in the context of oral carcinogenesis is unexplored. METHODS: In this study, wild-type (WT) and ACKR2 deficient mice (ACKR2-/- ) were treated with chemical carcinogen 4-nitroquinoline-1-oxide (4NQO) for induction of oral carcinogenesis...

Cancer of the unknown primary (CUP) makes up 2-4% of new head and neck squamous cell carcinoma (SCC) diagnoses. This scenario is recognised as a diagnostic challenge for head and neck surgeons. For all patients with proven cervical lymph node metastatic SCC without a clinically apparent primary site, the current UK guidelines recommends PET-CT, panendoscopy with directed biopsies and bilateral tonsillectomy as a standard of care.

The role of autophagy in tongue squamous cell carcinoma (TSCC) cisplatin resistance is unclear. We aimed to identify a possible synergistic effect of autophagy inhibitors and cisplatin in TSCC cells and explore the underlying mechanism. Our results indicate that autophagic flux was high in TSCC cells; Autophagy inhibitor bafilomycin A1 increased cisplatin cytotoxicity in TSCC cells by inhibiting lysosomal uptake of platinum and enhancing intracellular platinum ion binding to DNA; Autophagy gene (Atg5) knockout in TSCC cells did not duplicate the above-mentioned sensitization of bafilomycin A1...

The long noncoding RNA (lncRNA) H19 has been described to participate in various tumors metastasis. Nevertheless, whether H19 promotes or impedestongue squamous cell carcinoma (TSCC) cells migration and invasion remains controversial. Here, we found that the expression of H19 was elevated in TSCC tissues compared with adjacent normal tissues. Moreover, we demonstrated that the expression of H19 was higher in metastasized tumors compared with un-metastasized tumors. Consistently, TSCC cells express higher levels of H19 than human squanous cells...

BACKGROUND: Although perineural invasion (PNI) is recognized as an adverse prognostic factor in oral tongue squamous cell carcinoma (SCC), the patterns of failure are poorly defined. METHODS: Patients with oral tongue SCC who received primary surgical treatment were identified. Specimens were reviewed by head and neck pathologists. Disease-specific survival (DSS) and locoregional recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), and distant recurrence-free survival (DRFS) were calculated...

The insulin receptor (INSR) and insulin-like growth factor 1 receptor (IGF1R) have been reported to be involved in the tumorigenesis and metastasis of various malignancies. The aim of our study was to investigate and compare the effects of INSR and IGF1R on the tumorigenesis and metastasis of tongue squamous cell carcinoma (TSCC) and explore the possible mechanism(s) involved. We found that INSR had the same up-regulated expression pattern as IGF1R in TSCC tissues. INSR and IGF1R up-regulation were correlated with each other and associated with lymph node metastasis and poor prognosis...

A 21-year-old female patient underwent wide excision of the buccal mucosa and tongue as well as selective neck dissection due to squamous cell carcinoma on the left side of the tongue. She had a severe limitation in opening her mouth, owing to fibrosis of the mucosa and scar contracture after adjuvant radiation therapy. Reconstruction of the oral mucosa and tongue defect was performed after removal of the scar to improve mouth opening. An anterolateral thigh (ALT) flap was used, trimmed to an adipofascial flap for the reconstruction of the thin and pliable oral mucosa and tongue...

OBJECTIVES: Tobacco usage is the strongest risk factor in the development of oral squamous cell carcinoma (OSCC), which mandates careful screening for oral cancers in smokers. However, there are indications that oral potentially malignant lesions, such as oral epithelial dysplasia (OED), in non-smokers (NS) have a higher cancer risk than those in smokers. Without tobacco as an etiology, the development of these lesions in NS may suggest genetic susceptibility. The increasing incidence of OSCC in NS calls for a better understanding of the natural history of OED in NS as compared to that of smokers...

This study investigated a case of spindle cell carcinoma (SpCC) in tongue pathological lesions. The patient experienced a local recurrence and distant metastasis after surgical intervention. Although standard chemotherapy was administered, a granulomatous mass continued to develop. This aggressive growth led to survival of the tumor. Secondary debulking surgery was performed to improve the patient's quality of life at the request of the patient. Using a tissue sample derived from the secondary debulking surgery, we performed an analysis of the tumor's cell surface antigens, differentiation potential, metastatic ability, and inhibition potential by anticancer reagents...

BACKGROUND: Thyroid carcinoma is a very rare tumor in the pediatric age group, accounting for only 1.5-3% of childhood carcinomas in the United States and Europe. We aimed to identify the risk of a second malignancy among pediatric thyroid cancer survivors. METHODS: The cohort analysis consisted of pediatric cancer patients aged less than 20 years, diagnosed with a primary thyroid cancer, identified by site code ICD-0-3: C739, and reported to the SEER 9 database between 1973 and 2013...

OBJECTIVES/HYPOTHESIS: The outcomes of unilateral radiotherapy treatment for patients with p16/HPV-positive squamous cell carcinomas of unknown primary (SCCUP) affecting cervical lymph nodes are under-reported. Compared to radiating large volumes of the pharyngeal axis (the more common approach), this is potentially a much less toxic treatment for a good prognosis group. STUDY DESIGN: Retrospective cohort study. METHODS: We identified patients with SCCUP who were treated radically at our center and did not have parotid or isolated level IV or V nodal involvement...

Oral carcinoma develops from squamous epithelial cells by the acquisition of multiple (epi) genetic alterations that target different genes and molecular pathways. Herein, we performed a comprehensive genomic and epigenetic characterization of the HSC-3 cell line through karyotyping, multicolor fluorescence in situ hybridization, array comparative genomic hybridization, and methylation-specific multiplex ligation-dependent probe amplification. HSC-3 turned out to be a near-triploid cell line with a modal number of 61 chromosomes...

BACKGROUND: Primary intestinal-type adenocarcinoma of the tongue is rare. This represents the first reported case of a primary mixed adenoneuroendocrine carcinoma (MANEC) of the tongue arising within a congenital enteric cyst. METHODS: A 52-year-old man presented with a midline tongue mass that was connected to the mucosal surface with an epithelial-lined sinus tract. Morphological examination and immunohistochemical profiling of the neoplasm were performed. RESULTS: Histopathological evaluation showed a primary MANEC arising within a preexisting congenital enteric cyst, comprising both adenocarcinoma and neuroendocrine components...
