DNA aneuploidy is an imbalance of chromosomal DNA content that has been highlighted as a predictor of biological behavior and risk of malignant transformation. To date, DNA aneuploidy in oral potentially malignant diseases (OPMD) has been shown to correlate strongly with severe dysplasia and high-risk lesions that appeared non-dysplastic can be identified by ploidy analysis. Nevertheless, the prognostic value of DNA aneuploidy in predicting malignant transformation of OPMD remains to be validated. The aim of this meta-analysis was to assess the role of DNA aneuploidy in predicting malignant transformation in OPMD...

WNT5A is a secreted signaling protein that promotes migration and invasion of oral squamous cell carcinoma (OSCC) cells through activation of non-canonical WNT signaling. Here, we examined expression of WNT5A, β-catenin, and E-cadherin by immunohistochemistry in 21 human diagnostic incision biopsies that each had regions of oral mucosa with a normal appearance adjacent to the affected tissue, dysplasia, and OSCC. We also investigated the effect of recombinant WNT5A (rWNT5A) on expression of the cell-adhesion proteins E-cadherin and β-catenin by western blot analysis...

Oral squamous cell carcinomas (OSCC) can arise from potentially malignant disorders, such as leukoplakia. The immune system plays an important role recognizing tumour precursor cells. However, due to immunoediting mechanisms cancer cells are able to escape immune system surveillance. OBJECTIVE: Evaluate the profile of dendritic (Langerhans and plasmacytoid) and T cells in OSCC and oral epithelial dysplasia (OED) and correlate these findings with clinical data. MATERIALS AND METHODS: Fifty cases of OSCC and 48 of OED were immunostained for CD1a and CD83 dendritic Langerhans cells (DLC), plasmacytoid dendritic cells (pDC) CD303 and CD8 followed by quantitative analysis...

INTRODUCTION: MicroRNA (miRNA) 320a and vascular endothelial growth factor receptor 2 (VEGFR-2) expression as the angiogenic biomarkers might be therapeutic targets in Oral lichen planus (OLP). IL-6 and C-reactive protein (CRP) could be prognostic in OLP, dysplastic OLP and Oral squamous cell carcinoma (OSCC). Therefore, their salivary detections as the noninvasive tools were aimed in this study. MATERIALS AND METHODS: Histopathologic examinations were carried out to distinguish the patients with dysplastic OLP and OSCC...

BACKGROUND: Early detection of oral squamous cell carcinoma (OSCC) remains one of the most efficient ways to ensure patient survival and improved quality of life. Although specific biomarkers related to OSCC have been investigated, a useful biomarker that assesses the transition potential of potentially malignant lesion to OSCC remains to be found. Osteopontin (OPN) has been recognized as an important factor in tumorigenesis and their expression in OSCC have been investigated earlier...

PURPOSE: Increasing evidence has shown that Bcl-2 inhibitor of transcription 1 (Bit1) involves a variety of biological processes in the process of tumor development and progression. We hypothesized that Bit1 would be overexpressed in oral squamous cell carcinoma (OSCC); therefore, we examined Bit1 gene expression and protein production, as well as explored the effect of elevated Bit1 levels on OSCC cells. MATERIALS AND METHODS: We investigated the use of quantitative real-time reverse transcription-polymerase chain reaction and immunohistochemistry analysis for Bit1 messenger RNA and protein levels...

BACKGROUND: The strongest risk factor for oesophageal adenocarcinoma is reflux disease, and the rising incidence of this coincides with the eradication of Helicobacter pylori, both of which might alter the oesophageal microbiota. We aimed to profile the microbiota at different stages of Barrett's carcinogenesis and investigate the Cytosponge as a minimally invasive tool for sampling the oesophageal microbiota. METHODS: In this case-control study, 16S rRNA gene amplicon sequencing was done on 210 oesophageal samples from 86 patients representing the Barrett's oesophagus progression sequence (normal squamous controls [n=20], non-dysplastic [n=24] and dysplastic Barrett's oesophagus [n=23], and oesophageal adenocarcinoma [n=19]), relevant negative controls, and replicates on the Illumina MiSeq platform...

Chronic hyperplastic candidiasis (CHC), earlier known as candidal leukoplakia, is a variant of oral candidiasis that classically presents as a white patch on the commissures of the oral mucosa and it is mostly caused by Candida albicans. Clinically, the lesions are usually asymptomatic and regress after appropriate antifungal therapy and correction of the underlying cause. If the lesions are untreated, a small portion may develop dysplasia and later progress into carcinoma. The purpose of this article is to report a case of CHC in a 57-year-old male patient with a significant smoking habit, who presented with a thick, nonscrapable, brownish-white coating on the dorsum of the tongue for 9 years...

INTRODUCTION: Mast cells have been implicated in promoting angiogenesis in malignant tumors of lung, oesophagus and breast, but there are few studies on Oral Squamous Cell Carcinomas (OSCC). Most oral squamous cell carcinomas arise from pre-existing precancerous lesions exhibiting epithelial dysplasia. AIM: The present pilot study attempts to compare Mast Cell Density (MCD), Microvessel Density (MVD), Microvessel Area (MVA) histomorphometrically between normal buccal mucosa, severe epithelial dysplasia and OSCC and to correlate the role of mast cells and angiogenesis in tumor progression...

Nanoparticle-based contrast agents have been used as an imaging tool for selectively detecting cancerous processes. We aimed to evaluate the detection sensitivity of reflection measurements of gold nanorods (GNRs) bio-conjugated to anti-epidermal growth factor receptor (GNRs-EGFR) monoclonal antibodies in discriminating benign from premalignant and malignant human oral lesions. Tissue sections incubated with GNRs-EGFR and the reflectance spectrum was measured using hyperspectral microscopy. Reflectance intensity increased with the progression of the disease, lowest in the control group and increasing as the dysplastic changes increase (P<0...

OBJECTIVE: The standard of care for premalignant lesion risk assessment is dysplasia grading by histopathology. With significant overlap between dysplasia grades and high inter- and intraobserver variations, histopathology dysplasia grading alone is not a useful prognostic tool. Our aim is to investigate whether a method for quantitatively assessing S100A7, a prognostic biomarker, using image analysis can better predict clinical outcome in cases with oral dysplasia. STUDY DESIGN: Using the Visiopharm image analysis system, we analyzed a cohort of 150 oral biopsy samples to build and test Straticyte, a model for individualized assessment of the 5-year risk of progression of oral precancerous lesions to invasive squamous cell carcinomas...

Oral cancers are easily accessible compared to many other cancers. Nevertheless, oral cancer is often diagnosed late, resulting in a poor prognosis. Most oral cancers are squamous cell carcinomas that predominantly develop from cell hyperplasias and dysplasias. DNA damage is induced in these tissues directly or indirectly in response to oncogene-induced deregulation of cellular proliferation. Consequently, a DNA Damage response (DDR) and a cell cycle checkpoint is activated. As dysplasia transitions to cancer, proteins involved in DNA damage and checkpoint signaling are mutated or silenced decreasing cell death while increasing genomic instability and allowing continued tumor progression...

BACKGROUND: Mitosis is a process of cell division resulting in two genetically equivalent daughter cells. Excessive proliferation of cells due to mitosis is the hallmark in pre cancer and cancer. AIMS: This study was conducted to count the number of mitotic figures in normal oral mucosa, oral epithelial dysplasia and squamous cell carcinoma in both Hematoxylin and Eosin (H&E) and Crystal Violet stained sections. Also the overall number of mitotic figures with both stains were compared along with the evaluation of staining efficacy of both the stains...

The risk of malignant transformation in oral preneoplastic lesions (OPLs) is challenging to assess. The objective of the present study was to determine the expression of ELAV like RNA binding protein 1 (HuR) and podoplanin in OPLs, and to evaluate the use of each protein as biomarkers for the risk assessment of malignant transformations. Immunohistochemistry for HuR and podoplanin was performed on the tissues of 51 patients with OPL, including cases of low grade dysplasia (LGD) and high grade dysplasia (HGD)...

Oral squamous cell carcinoma (OSCC) is a lethal disease, with rising incidence. There were 6767 new OSCC cases and 2056 deaths in the UK in 2011. Cancers are preceded by oral potentially malignant disorders (PMDs), recognizable mucosal diseases harbouring increased SCC risk, offering clinicians a 'therapeutic window' to intervene. Contemporary practice remains unable to predict lesion behaviour or quantify malignant transformation risk. No clear management guidelines exist and it is unclear from the literature whether early diagnosis and intervention prevents cancer...

Head and neck cancer (HNC) is the sixth most common malignancy worldwide. Squamous cell carcinoma, the primary cause of HNC, evolves from normal epithelium through dysplasia before invading the connective tissue to form a carcinoma. However, less than 18% of suspicious oral lesions progress to cancer, with diagnosis currently relying on histopathological evaluation, which is invasive and time consuming. A non-invasive, real-time, point-of-care method could overcome these problems and facilitate regular screening...

BACKGROUND: Oral Squamous cell carcinoma (OSCC) results from genetic damage, leading to uncontrolled cell proliferation of damaged cells and the cell death. In the course of its progression, visible changes are taking place at the cellular level (atypical) and the resultant at the tissue level (epithelial dysplasia). OBJECTIVES: The Aim of the present study was to evaluate and compare the expressions of intensity of p21 and Bcl-2 in Leukoplakia, oralsubmucous fibrosis (OSMF) and oral squamous cell carcinoma...
