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

2. Progressive Increase Trend in HPV-Related Oropharyngeal Squamous Cell Carcinoma in Brazil
Abstract Introduction The prevalence of oropharyngeal squamous cell carcinoma (OSCC) related to Human Papillomavirus (HPV) is rising in the whole world. Objective To access the prevalence and temporal trend of HPV infection in oropharyngeal cancer by analyzing the expression of the p16 protein. Methods We conducted a transversal study in a Brazilian refer

4. 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

5. 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

6. 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

7. 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

8. Epidemiological and clinicopathological assessment of potentially malignant lesions and oral cancer diagnosed in the family health strategy and specialty dental centers in two regions in the state of Cearà / AvaliaÃÃo epidemiolÃgica e clÃnico-patolÃgica de lesÃes potencialmente malignas e cÃncer de boca diagnosticadas na estratÃgia saÃde da famÃlia e centros de especialidades odontolÃgicas em duas regiÃes do interior do Estado do CearÃ
BACKGROUND: Oral malignant and potentially malignant lesions (LPM) are commom in oral cavity and diagnosis network health structure is required to improve early diagnosis. OBJECTIVE: This research had evaluated primary and secondary health care integration in oral cancer diagnosis evaluating contact with risk factors and presence of LPM and Oral squamous cel

9. Avaliação da linfangiogênese em carcinoma de células escamosas de boca e de sua associação com metástases nodais
Recent studies have demonstrated that metastatic behavior of some tumors is facilitated by lymphangiogenesesis in primary tumor or in lymph node environment. In the present study of lymphangiogenesis 36 paraffin-embedded samples of oral squamous cell carcinoma (OSCC) and associated lymph nodes were used. Lymphatic vessels and microvessels densities (LVD and

10. Immunohistochemical staining of Langerhans cells in HPV-positive and HPV-negative cases of oral squamous cells carcinoma
The Human Papillomavirus (HPV) has been strongly implicated in development of some cases of oral squamous cell carcinoma (OSCC). However, the immunological system somehow reacts against the presence of this virus. Among the cells involved in such mechanism of defense Langerhans cells (LC) stand out, which are responsible for processing and presenting antigen

11. Immunohistochemical expression of p53, p16 and hTERT in oral squamous cell carcinoma and potentially malignant disorders
Oral carcinogenesis is a multi-step process. One possible step is the development of potentially malignant disorders known as leukoplakia and erytroplakia. The objective of this study was to use immunohistochemistry to analyze the patterns of expression of the cell-cycle regulatory proteins p53 and p16INK4a in potentially malignant disorders (PMD) of the ora

12. Poliformismos genéticos no câncer de cabeça e pescoço: análise de risco e evolução clínica / Genetic polymorphisms in head and neck cancer: analysis of risk and clinical evolution
The squamous cell carcinoma of the head and neck (HNSCC) is considered one of the most prevalent cancers in developing countries, detected nearly always in well-advanced phases with few effective treatment options, which reduce the survival rate to five years in 50% of the patients. The main risk factors associated with it are tobacco and alcohol intake, fol
