1. Estudo comparativo da expressão imuno-histoquímica do ki-67 em carcinoma epidermóide de língua em pacientes jovens e idosos
The squamous cell carcinoma (SCC) is the most common malignant neoplasm of epithelial origin in oral cavity and present high capacity to invade adjacent structures. Traditionally, SCC has a predominance of 50 years male patients with long-time use of tobacco and alcohol, and the tongue is the most affected anatomic site. At present, there is an increasing in

2. Relação da imunoexpressão da bmp-2, bmpr-ia e bmpr-ii com o perfil clínico-patológico em carcinoma epidermóide de lábio inferior
Atualmente as proteínas morfogenéticas do osso (BMPs) têm efetiva participação no crescimento de neoplasias malignas. Sabendo que são escassos os trabalhos envolvendo BMPs e o carcinoma epidermóide oral, este trabalho realizou um estudo imunoistoquímico da BMP-2, BMPR IA e BMPR II em carcinomas epidermóides (CE) de lábio inferior relacionando com o

3. Correlação das caracteristicas clinicas, histopatologicas e expressão de acido graxo sintase e ErbB2, em carcinomas espinocelulares bucais de pacientes com recidiva local precoce / Correlation among clinical and pathological characterisitics and expressions of FAS and ErbB2 in early recurrent oral squamous cell carcinoma
Oral squamous cell carcinoma (SCC) recurs locally in about 30% of cases. The recognition of reliable factors may result in the tumor behavior prediction and prevent treatment failures. The purpose of this study was to evaluate the correlation among clinical, histopathological and immunohistochemical features in oral SCC with early local recurrence. Sixty-nin

4. Comparison between presence and distribution of the extracellular matrix proteins and malignancy histological grading in the lip SCC invasive front / "Comparação entre presença e distribuição de proteínas da matriz extracelular e graduação histológica de malignidade da fronte de invasão no carcinoma epidermóide de lábio"
Interaction between tumor cells and stroma plays a central role in cancer progression. Local growth and invasion of neoplasms depend on the controlled modification of components of the extracellular matrix. The invasive front has been considered the most aggressive part of a tumor whose cells have the greatest ability to invade surrounding tissue. Therefore,

5. Papilomavírus humano (HPV) e células de Langerhans em carcinoma epidermóide oral
The Human Papillomavirus (HPV) has been strongly implicated on 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 on such mechanism of defense detaches the Langerhans cells (LC), which are responsible for processing and presenting anti

6. Expressão imuno-histoquímica da e-caderina e do CD44v6 em carcinoma epidermóide de lábio inferior e língua
The objective of this study was perform, by the streptoavidin-biotin technique, an immunohistochemical analysis of the E-cadherin and CD44v6 in 15 lower lip squamous cell carcinomas and 15 of tongue, with varied histologic gradation of malignidade, in order to establish a possible relation between the expression these proteins and the anatomical localization

7. Detecção de HPV e avaliação do índice de proliferação celular entre carcinomas espinocelulares e carcinomas verrucosos de boca / HPV detection and evaluation of the index of cell proliferation between squamous cell carcinoma and verrucous carcinoma of the mouth
Squamous cell carcinoma (SCC) is the most common malignant neoplasm of the bucal cavity, and one of its variants is verrucous carcinoma (VC), of low degree malignancy. The diagnosis of VC is difficult from the clinical as well as from the histopathological point of view, and an effective diagnosis is vital when deciding on the treatment and prognosis of this

8. Expressão imuno-histoquimica da cicloxigenase-2 e p53 em cancinoma epidermóide oral
O carcinoma epidermóide é a neoplasia maligna mais comum na cavidade oral, representando mais de 90% das malignidades nesta localização. As cicloxigenases (COXs) são enzimas chave no metabolismo do ácido aracdônico e síntese de prostaglandinas, sendo expressas basicamente sob duas formas: uma constitutiva (COX-1) e uma induzida (COX-2). Níveis eleva
