There is controversy regarding prognosis and treatment of young patients with oral cavity cancer compared to their older counterparts. We conducted a retrospective case-matched analysis of all adult patients younger than 40 years and treated at our institution for a squamous cell carcinoma of the oral cavity. Only non-metastatic adult patients (age >18) with oral tongue cancer were eventually included and matched 1:1 with patients over 40 years of age, at least 20 years older than the cases, with same T and N category and treatment period...

INTRODUCTION: Intracranial enterogenous cysts are rare and mainly occur in the posterior fossa. These cysts are usually extra-axial, midline, anterior to the brainstem, or at the cerebellopontine angle. We report a case of an enterogenous cyst in which diagnosis was difficult because the lesion showed atypical pathologic findings. CASE PRESENTATION: A healthy 41-year-old man complained of paroxysmal occipital headaches lasting over a week, with increased severity for 3 days accompanied by slight dizziness and mild nausea...

BACKGROUND: Long noncoding RNAs (lncRNAs) are more than 200 nucleotides in length and lack transcriptional ability. The biological function of lncRNAs in oral squamous cell carcinoma (OSCC) remains unclear. The aim of this study was to identify the dysfunction of lncRNA in OSCC. RESULTS: We analyzed the transcriptome profiles of human OSCC tissues and paired adjacent normal tissues from two patients through a next-generation sequencing approach. A total of 14 lncRNAs were upregulated (fold change ≥3) and 13 were downregulated (fold change ≤-3) in OSCC tissues compared with the adjacent normal tissues...

Human Papillomavirus is the major etiological agent in the development of cervical cancer but not a sufficient cause. Despite significant research, the underlying mechanisms of progression from a low-grade squamous intraepithelial lesion to high grade squamous intraepithelial lesion are yet to be understood. Deregulation of viral gene expression and host genomic instability play a central role in virus-mediated carcinogenesis. Key events such as viral integration and epigenetic modifications may lead to the deregulation of viral and host gene expression...

The most common histological classification of bile duct cancer is adenocarcinoma and squamous cell carcinoma (SCC) is relatively rare. We report a case of a 78-year-old man with SCC of the extrahepatic bile duct associated with metachronous para-aortic lymph node metastasis. He had undergone subtotal stomach-preserving pancreatoduodenectomy. The pathological findings demonstrated moderately differentiated SCC of the distal extrahepatic bile duct (T1N1M0, stage IIB). 6 months after surgery, recurrence of the para-aortic lymph node was shown in abdominal CT...

Upregulation of eIF4E is associated with poor clinical outcome in many human cancers and represents a potential therapeutic target. However, the function of eIF4E remains unknown in oral tongue squamous cell carcinoma (OTSCC). In this work, we show that ribavirin, an anti-viral drug, effectively augments sensitivity of OTSCC cells to paclitaxel via inhibiting mTOR/eIF4E signaling pathway. Ribavirin dose-dependently inhibits proliferation and induces apoptosis in SCC-9 and CAL27 cells. Combination of ribavirin and paclitaxel are more effectively in inhibiting proliferation and inducing apoptosis in OTSCC cells...

Hereditary epidermolysis bullosa (EB) is a heterogeneous group of rare genetic diseases characterized by fragile skin and/or mucous membrane, and it may be either local or generalized. It is caused by mutations in genes encoding different proteins involved mainly in the structure and function of the dermal-epidermal junction. Nineteen genes have so far been identified. They are classified by level of skin cleavage (from top to bottom) into four groups: EB simplex, junctional EB, dystrophic EB and Kindler syndrome...

BACKGROUND: The robust desmoplasia associated with head and neck squamous cell carcinoma (HNSCC) suggests that the tumor microenvironment may be an important component in the pathophysiology of this cancer. Moreover, the high recurrence rate and poor clinical response to chemotherapy and radiation treatment further underscores that the non-cancerous cells of the microenvironment, such as mesenchymal stromal cells (MSCs), cancer associated fibroblasts (CAFs), and pericytes, may be important in the pathophysiology of HNSCC...

Oral cancer is a subtype of head and neck cancer which represents 2.65% of all human malignancies. Most of oral cancer is histopathologically diagnosed as oral squamous cell carcinoma (OSCC). OSCC is characterized by a high degree of local invasion and a high rate of metastasis to the cervical lymph nodes. How to prevention and treatment of OSCC is important and imperative. Here, we investigated the therapeutic effect and molecular mechanism of cantharidin, an active compound isolated from blister beetles, on OSCC in vitro...

Metastasis is associated with poor prognosis in cancers. Exosomes, which are packed with RNA and proteins and are released in all biological fluids, are emerging as an important mediator of intercellular communication. However, the function of exosomes remains poorly understood in cancer metastasis. Here, we demonstrate that exosomes isolated by size-exclusion chromatography from a highly metastatic human oral cancer cell line, HOC313-LM, induced cell growth through the activation of ERK and AKT as well as promoted cell motility of the poorly metastatic cancer cell line HOC313-P...
