RESUMO
RESUMO O carcinoma de células escamosas é uma neoplasia maligna que afeta as estruturas e os tecidos da cavidade oral. Interleucinas (IL) sintetizadas a partir de um tumor modulam uma cascata de reações que poderá influenciar o prognóstico da doença. Objetiva-se investigar na literatura se as interleucinas são mediadores que influenciam negativamente ou positivamente o prognóstico de pacientes com carcinoma de células escamosas intraoral. Um estudo de revisão sistemática foi realizado segundo as instruções do Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). As bases de dados PubMed (incluindo MedLine), Scopus, Web of Science, SciELO e Latin American and Caribbean Health Sciences (LILACS) foram utilizadas como fontes de estudo primárias; OpenGrey e OpenThesis, utilizadas para pesquisar a "literatura cinzenta". A busca realizada em sete bases de dados gerais resultou em um conjunto de 858 estudos, enquanto a realizada em duas bases de dados para literatura cinza, em 82 estudos, totalizando 940 pesquisas. Destas, 15 foram selecionadas para a presente revisão sistemática (oito estudos apresentaram baixo risco de viés; quatro, moderado risco de viés; e três, alto risco de viés). Apesar de poderem atuar nas vias de resposta imune antitumoral, as IL avaliadas nesta revisão (IL-4, IL-6, IL-8, IL-10, IL-12 e IL-13) tendem a apresentar uma resposta associada à intensificação do processo de carcinogênese e ao prognóstico desfavorável em pacientes portadores do carcinoma de células escamosas intraoral.ABSTRACT Squamous cell carcinoma is a malignant neoplasm that affects the structures and tissues of the oral cavity. Interleukins (IL) synthesized from a tumor modulate a cascade reaction that may influence the prognosis of the disease. We aim to investigate in the literature whether interleukins are mediators that negatively or positively influence the prognosis of patients with oral squamous cell carcinoma. A systematic review study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) instructions. PubMed (including MedLine), Scopus, Web of Science, SciELO and Latin American and Caribbean Health Sciences (LILACS) databases were used as the primary sources for the study; OpenGrey and OpenThesis were used to search for "gray literature". The search conducted in seven general databases resulted in a set of 858 studies, while the search conducted in two databases for gray literature resulted in 82 studies, totaling 940 studies. From these, 15 studies were selected for this systematic review (eight studies presented low bias risk; four studies presented moderate bias risk; and three studies presented high risk of bias). Although they may act on the anti-tumor immune response pathways, the IL evaluated in the present systematic review (IL-4, IL-6, IL-8, IL-10, IL-12 and IL-13) tend to present a response associated with the intensification of carcinogenesis and poor prognosis in patients with oral squamous cell carcinoma.
