Introduction:Cancer is the second cause of death in the world and the third primary cause in Iran. In this study, we examined the epidemiology of oral squamous cell carcinoma (OSCC) as the most common malignancy of the oral cavity and its related factors in Yazd Province, Iran, from 2001 to 2011. Materials and methods: This descriptive study evaluated the medical records of patients with OSCC ...
The present study was carried out to evaluate the effect of phagocytosis of killed yeast on the induction of apoptosis in two human solid tumors of the gastrointestinal (GI): the squamous cell carcinomas of the tongue (SCCA) are (SCC-4 and SCC-9) and the adenocarcinomas of the colon (ADENOCA) are (Caco-2 and DLD-1). Cancer cells were cultured with heat killed Saccharomyces cerevisiae, baker's a...
Synchronous lingual granular cell tumor and squamous cell carcinoma (case report) Dr. D. Sadri* *-Assistant Professor of Oral & Maxillofacial Pathology Dept. – Faculty of Dentistry – Tehran Islamic Azad University. Introduction: For the first time, Abrikossof described granular cell tumor in 1926. It was firstly believed that this tumor originated from skeletal muscle but using electron microsc...
Lymph node (LN) metastasis has been suggested as a major prognostic factor for oral cancer. Knockdown of the growth factors and receptors involved in these metastatic mechanisms could significantly reduce LN metastasis and improve the survival of oral cancer patients after treatment. The present study, therefore, aimed to evaluate the expression levels of the following growth factors and recept...
Background: Squamous Cell Carcinoma (SCC) of the tongue constitutes about 25% - 40% oral carcinomas. Most often, treatment failure occurs as local and regional recurrences. Currently, collection Lingual Lymph Nodes (LLNs) that are located on floor mouth has gained more attention. The lingual lymph nodes inconstant para intermediate appearing along course lymphatic vessels mouth. aim was to asse...
BACKGROUND Human papilloma virus (HPV) is an important risk factor for head and neck cancer, specifically oropharyngeal cancer, but its association with oral tongue squamous cell carcinoma (SCC) is uncertain. The objectives were to determine the HPV16 prevalence in oral tongue SCCs, its integration status and to correlate the expression of oncogenic proteins with targets. METHODS In this case...
Hypoxia-inducible factor-1α (HIF-1α) is a key regulator for tumor cells and tissues to adapt to hypoxic condition. Suppressing the expression of HIF-1α is important to evaluate its effect on cancer cells. This study was carried out to analyze the effect of HIF-1α on the biological activation of human tongue squamous cell carcinoma (TSCC) SCC-15 cells. In this experiment, deferoxamine mesylate (...
OBJECTIVES Oral cancer represents a health burden worldwide. Up to 90% of oral cancer cases are squamous cell carcinomas (SCC). The data on oral SCC in Yemen are lacking. The objective of this study therefore was to describe and analyze the demographic, clinical and histological characteristics of Yemeni patients with oral SCC. STUDY DESIGN In this cross-sectional study, two sets of retrospec...
PURPOSE Squamous cell carcinoma (SCC) of the tongue is a common malignancy of the oral cavity. Furin convertase activates several precursor matrix metalloproteinases involved in the degradation of the extracellular matrix. The pattern of expression of furin and vascular endothelial growth factor-C (VEGF-C), two key molecules in neoplasm development, was examined during the progression from norm...
We have established cell lines from six human squamous cell carcinomas (SCC) of the epidermis and tongue, using culture methods previously developed for clonal growth and serial cultivation of normal keratinocytes. The SCC lines all form rapidly growing, well-differentiated SCC's or progressively growing squamous cysts in nude mice. In contrast to normal keratinocytes, SCC cells form unstratifi...
