Oral cancer being one of the lethal cancers is generally detected at advanced stages and causes significant mortality world over. The unavailability of the reliable biomarkers and therapeutic targets/agents forms a bottleneck in the treatment of oral cancer. MicroRNAs are considered of immense therapeutic potential for the treatment of cancer. Consistently, in this study the role and therapeutic potential of miR-650 was explored in oral cancer. The analysis of miR-650 expression by qRT-PCR revealed significant (p < 0...

Introduction: Although red blood cell distribution width (RDW) has been reported to reflect inflammation and nutritional status and to predict prognosis in several different types of cancer, little is known about how RDW might be related to oral squamous cell carcinoma (OSCC). The present study aimed to investigate the prognostic value of preoperative RDW in OSCC patients. Materials and methods: We included 236 OSCC patients from Jinan Stomatological Hospital (Shandong, People's Republic of China) in this retrospective study...

The treatment of squamous cell carcinoma (SCC) involves surgery, chemotherapy, and/or radiotherapy, which can cause mucositis (inflammation of the oral mucosa that causes considerable pain and can compromise the continuity of oncological treatment). Photobiomodulation (PBM) has been successfully used in the treatment of mucositis, but doubts arise regarding the use of laser for areas in which tumor cells may remain. In this study, the effect of PBM on the viability, mitochondrial activity, proliferation, apoptosis, and migration of cells derived from oral SCC was evaluated...

Patients receiving immunosuppressive drugs to prevent organ transplant rejection exhibit a greatly increased risk of developing cutaneous squamous cell carcinoma (SCC). However, not all immunosuppressive drugs confer the same risk. Randomised, controlled trials demonstrate that switching renal transplant recipients receiving calcineurin inhibitor-based therapies to mammalian target of rapamycin (mTOR) inhibitors results in a reduced incidence of de novo SSC formation, and can even result in the regression of pre-existing premalignant lesions...

In the surgical management of oral squamous cell carcinoma (SCC) we aim to resect the tumour with clear margins in all planes. The aim of this study was to identify and compare overall survival in a group of 591 patients who had resections, and to relate this to the clearance of margins at the tumour bed. We used life tables to calculate survival at one, two, three, five, and 10 years after diagnosis by margin (clear=5mm or more; close=2-5mm; and involved=less than 2mm). Kaplan-Meier curves were produced for the margins alone, which were defined as clear in 480 patients (81%), close in 63 (11%), and involved in 48 (8%)...

We provide a non-melanoma skin cancer (NMSC) service for skin cancers of the head and neck in the south-west of England. We hypothesised that certain anatomical sites such as the nose and eyelid would have a higher incidence of close or involved margins than others, and that the choice of repair might influence the excised margins. We therefore retrospectively analysed the data of 500 consecutive NMSC that were operated on in the oral and maxillofacial surgery unit of Taunton and Somerset NHS Trust. The database reports were crosschecked against the Trust's own pathology reporting system to ensure that they were accurate...

Basaloid squamous cell carcinoma (BSCC) is a histologically distinct variant of SCC in the head-and-neck region it occurs most commonly in older men with a history of heavy smoking and alcohol abuse and usually presents as a high stage disease with widespread metastases and hence poor prognosis. BSCC is believed to arise from a totipotential primitive cell in the basal layer of the surface epithelium or from the salivary duct lining epithelium. BSCC is an uncommon tumor with a predilection for the upper aerodigestive tract, is a distinct variant of squamous carcinoma, due to its unique histological features and ominous clinical behavior...

BACKGROUND: Oral tongue squamous cell carcinoma (OTSCC) cells are highly proliferative and invasive. Lingonberry contains several polyphenolic compounds similar to curcumin. We hypothesize that fermented lingonberry juice (FLJ) has an anti-invasive and anti-proliferative effect on OTSCC cells similarly to curcumin, which is known to be anti-carcinogenic. MATERIALS AND METHODS: FLJ, curcumin dissolved in ethanol, or curcumin loaded in Candida extracellular vesicles (EVs) were added to more (HSC-3) and less aggressive (SCC-25) OTSCC cells...

Transcription factor SRY‑box 9 (SOX9) is a key regulator of chondrocyte differentiation and sex determination, and it is also involved in the progression of various types of human cancer. However, its putative association with oral squamous cell carcinoma (OSCC) remains elusive. The aim of the present study was to investigate the expression profiles of SOX9 in various oral epithelial lesions, including OSCC. We performed immunohistochemical analysis of SOX9 expression in surgical specimens of OSCC, which simultaneously exhibited different grades of epithelial lesions, and analyzed the correlation between SOX9 expression and several clinicopathological factors...

The risk of late complications including secondary malignancies is increased in long-term survivors of allogeneic hematopoietic stem cell transplants (HSCT). There is limited literature on the biological behavior and clinical features of squamous cell carcinoma (SCC) of head and neck post-HSCT. We present the clinical and pathologic characteristics on six patients who were diagnosed with SCC while in remission following an allogeneic HSCT. Median follow-up was 8 years. Five patients (83%) developed SCC of tongue and one developed esophageal SCC...
