ABSTRACT
Considerable evidence indicates that serotonergic mechanisms, particularly the serotonin transporter, are involved in alcoholism and tobacco use and are influenced by polymorphism of the promoter region of 5HTT (5-HTTLPR). As alcohol and tobacco consumption have been implicated in the pathogenesis of oral cancer, the purpose of this study was to investigate 5-HTTLPR polymorphism in patients with oral squamous cell carcinoma (OSCC) compared with a control group in a sample of Brazilian patients. One hundred and three patients affected by OSCC and 103 volunteers without OSCC were genotyped for 5-HTTLPR. Both groups were matched for age, sex and tobacco use. The chi-squared test was used for statistical analysis (α=0.05). There was no statistically significant difference in 5-HTTLPR genotypes between case and control group (p= 0.408). In conclusion, the present investigation demonstrated that serotonin transporter polymorphisms are not implicated in the OSSC development.
RESUMO
Consideráveis evidências indicam que mecanismos serotoninérgicos, particularmente o transportador de serotonina, estão envolvidos no alcoolismo e no uso de fumo e são influenciados pelo polimorfismo da região promotora do 5HTT (5-HTTLPR). Como o consumo de álcool e fumo está implicado na patogênese do câncer, o objetivo deste estudo foi investigar o polimorfismo 5-HTTLPR em pacientes com carcinoma bucal de células escamosas (CBCE) comparado com um grupo controle em uma amostra de pacientes brasileiros. Cento e três pacientes afetados por CBCE e 103 voluntários sem história de CBCE foram genotipados para 5-HTTLPR. Ambos os grupos foram pareados pela idade, gênero e uso de fumo. O teste do qui-quadrado foi usado para análise estatística. Não houve diferença estatística entre os genótipos dos grupos caso e controle (p= 0,408). Concluindo, a presente investigação demonstrou que os polimorfismos do transportador de serotonina não estão implicados no desenvolvimento do CBCE.
