1. Free three-dimensional image software in local extension assessment of oral squamous cell carcinoma: a pilot study
Abstract Objective: Oral Squamous Cell Carcinoma (OSCC) is conventionally treated by surgical resection, and positive surgical margins strongly increase local recurrence and decrease survival. This study aimed to evaluate whether a Three-Dimensional Segmentation (3DS) image of OSCC confers advantage over Multiplanar Reconstruction (MPR) of OSCC using images

3. Benzyl isothiocyanate inhibits invasion and induces apoptosis via reducing S100A4 expression and increases PUMA expression in oral squamous cell carcinoma cells
Benzyl isothiocyanate (BITC) has been shown to inhibit invasion and induce apoptosis of various types of cancer. However, its role on human oral squamous cell carcinoma (OSCC) cells is still not well elucidated. In the present study, we investigated the effect of BITC on apoptosis and invasion of SCC9 cells, and its underlying mechanisms in vitro and in vivo

4. Matrine from Vietnamese sophora root inhibits the growth of oral squamous cell carcinoma cells in vitro and in vivo
Abstract This study investigated the extraction of matrine from Vietnamese sophora root and its in vitro and in vivo inhibitory effects on oral squamous cell carcinoma (OSCC) cells. Matrine was extracted from Vietnamese sophora root using microwave-assisted extraction technology and purified using macroporous adsorption resin. Human OSCC Tca8113 cells were

5. Experience in Intra-arterial Chemotherapy using Two Protocols for the Treatment of OSCC over Two Decades at the University Hospital Vienna
OBJECTIVES: This retrospective study performed a comprehensive analysis of the usage of intra-arterial chemotherapy (iaCh) for locally recurrent UICC stage IV oral squamous cell carcinoma (OSCC) over two decades at the Department of Cranio-Maxillofacial and Oral Surgery at the University Hospital Vienna to assess the utility of its future use. METHODS: Bet

6. Ki-67 protein predicts survival in oral squamous carcinoma cells: an immunohistochemical study
Abstract The aim of this study was to identify the expression of Ki-67 and MCM3 in oral squamous cell carcinoma (OSCC) as well as to address the correlation with patient survival and clinical features. Samples were collected from 51 patients with OSCC who presented for follow-up. Immunohistochemical expression of Ki-67 and MCM3 in all groups was performed. T

7. Serum big endothelin-1 as a biomarker in oral squamous cell carcinoma patients: an analytical study
Detection of abnormally elevated levels of molecules in patients with oral cancer may be useful in early diagnosis. These markers can be included in current Histopathology grading and in TNM staging systems of Oral Squamous Cell Carcinoma (OSCC) to make it more efficient. Several pro-angiogenic molecules have been assessed for the same reason. Endothelin-1 (

8. A 10-year analysis of the oral squamous cell carcinoma profile in patients from public health centers in Uruguay
The aim of this study was to evaluate the demographic, clinical, and therapeutic characteristics and predictive factors of poor prognosis in patients with primary oral squamous cell carcinoma (OSCC) in Uruguay. Medical records of patients with the diagnosis of primary OSCC treated between 2000 and 2010 in Uruguayan public hospitals were selected. Data on dem

9. Expression of epithelial-mesenchymal transition markers at the invasive front of oral squamous cell carcinoma
Oral squamous cell carcinoma (OSCC) is one of the most common malignances. In epithelial-mesenchymal transition (EMT), epithelial cells switch to mesenchymal-like cells exhibiting high mobility. This migratory phenotype is significant during tumor invasion and metastasis. Objective : The aim of this study is to evaluate the expression of the EMT markers E-ca

10. Overexpression of S100A4 as a biomarker of metastasis and recurrence in oral squamous cell carcinoma
S100A4, a biomarker of epithelial mesenchymal transition (EMT), plays an important role in invasion and metastasis by promoting cancer cell motility. In oral squamous cell carcinoma (OSCC), metastasis results in 90% of cancer associated mortality. Objective: To investigate the role of S100A4 expression as an important component of the epithelial mesenchymal

11. Oral squamous cell carcinoma: clinicopathological features from 346 cases from a single Oral Pathology service during an 8-year period
Epidemiological data from oral squamous cell carcinoma (OSCC) is mostly derived from North American, European and East Asian populations. OBJECTIVE: The aim of this study was to report the demographic and clinicopathological features from OSCC diagnosed in an Oral Pathology service in southeastern Brazil in an 8-year period. MATERIAL AND METHODS: All OSCC

12. Concordance between cytopathology and incisional biopsy in the diagnosis of oral squamous cell carcinoma
Oral cytopathology is a simple, non-invasive technique that could be used for early detection of oral premalignant and malignant lesions, but the effectiveness of this diagnostic approach remains controversial. The aim of this study was to evaluate the sensitivity, specificity, positive and negative predictive values, and accuracy of cytopathology for diagno
