ABSTRACT

Introduction:

Vascular endothelial growth factor is thought to be an important angiogenic factor involved in tumor growth, progression, and metastasis.

Objective:

The present study evaluated the relation between tissue expression, serum and salivary levels of vascular endothelial growth factor in head and neck squamous cell carcinomas, and their correlation with clinicopathologic features.

Methods:

Samples were collected from 30 patients with head and neck squamous cell carcinomas and 24 healthy volunteers. Immunohistochemical analysis was used for tissue expression and enzyme-linked immunosorbent assay was employed to measure serum and salivary levels.

Results:

No vascular endothelial growth factor staining was observed in normal tissues, whereas vascular endothelial growth factor expression was seen in 6 patients (20%). Mean serum level of VEGF was 83.7 ± 104.47 in patients and 50.04 ± 32.94 in controls. Mean salivary level of vascular endothelial growth factor was 174.41 ± 115.07 in patients and 149.58 ± 101.88 in controls. No significant difference was found by Mann-Whitney test between controls and patients (p = 0.411, p = 0.944, respectively). No correlation was found between vascular endothelial growth factor tissue expression and its serum and salivary level.

Conclusion:

Overexpression of vascular endothelial growth factor was found in head and neck squamous cell carcinoma patients, suggesting its role in the pathogenesis of head and neck squamous cell carcinoma, but no relation was found between tissue expression, serum levels, and salivary levels of this marker. .
RESUMO

Introdução:

Acredita-se que o fator de crescimento vascular endotelial (FCEV) seja um importante fator angiogênico envolvido no crescimento, na progressão e na metástase tumoral.

Objetivo:

O presente estudo avalia a relacão entre a expressão tecidual e os níveis séricos e salivares do FCEV em carcinomas de células escamosas da cabeca e pescoco (CCECPs) e sua correlacão com aspectos clinicopatológicos.

Método:

Foram coletadas amostras de 30 pacientes com CCECP e de 24 voluntários saudáveis. Utilizamos análise imuno-histoquímica para a expressão tecidual e ELISA para determinação dos níveis séricos e salivares.

Resultados:

Não foi observada coloração para FCEV nos tecidos normais, enquanto que foi observada expressão de FCEV em seis pacientes (20%). O nível sérico médio de FCEV foi 83,7 ± 104,47 em pacientes e 50,04 ± 32,94 em controles. O nível salivar médio de FCEV foi de 174,41 ± 115,07 em pacientes e 149,58 ± 101,88 em controles. Não foi observada diferenca significativa pelo teste de Mann-Whitney entre controles e pacientes (respectivamente, p = 0,411, p = 0,944). Não foi observada relacão entre a expressão tecidual de FCEV e seus níveis séricos e salivares.

Conclusão:

A expressão elevada de FCEV foi observada em pacientes com CCECP, e isso sugere seu papel na patogênese de CCECP, mas não foi observada relacão entre a expressão tecidual e os níveis séricos e salivares desse marcador. .
