dc.description.abstractThe objective of this research was to describe the association of the main factors related to the pathophysiology of obesity with the development of gastric cancer. Methods: This work constitutes a narrative bibliographic review. In this research, we used the virtual databases: Capes Periodicals, Virtual Health Library and Pubmed. 57 articles published in the period from 2005 to 2019 that included content compatible with the objectives of this study were included. Results: Obesity is among the fastest growing diseases in the world, treatment is inadequate and the associated disorders, including gastric cancer, have high morbidity and mortality. Obesity can affect the intestinal microbiota resulting in dysbiosis, through the interaction between nutritional, endocrine and metabolic factors, which contribute to activate a process of low-grade chronic inflammation leading to increased cell proliferation and angiogenesis and decreased cell apoptosis, culminating in in the development of gastric cancer. Thus, it is important to note that adipose tissue responds to the stimulation of extra nutrients via adipocyte hyperplasia and hypertrophy. With adipocyte hypertrophy, the adipose tissue becomes hypoperfused, which creates areas of microhypoxia, activating the nuclear transcription factor NFkB pathways, increasing the expression of genes involved in inflammation with greater release of cytokines. Thus, high levels of adiponectin and leptin, sex steroids, glucocorticoids, inflammatory mediators and insulin-like growth factors, can result in oxidative tissue stress and the neoplastic transformation of gastric cells. Conclusion: A greater understanding of the mechanisms of obesity-induced carcinogenesis is needed to develop more effective methods to prevent or treat gastric cancer. A greater understanding of the molecular mechanisms can lead to the identification of new therapeutic targets Additional studies on the mechanisms involved in gastric carcinogenesis are necessary, as this disease still has high rates of morbidity and mortality.pt_BR

dc.description.resumoO objetivo deste estudo foi descrever a associação dos principais fatores relacionados com a fisiopatologia da obesidade com o desenvolvimento do câncer gástrico. Métodos: Este trabalho constitui uma revisão bibliográfica narrativa. Nesta pesquisa utilizou-se as bases de dados virtuais: Periódicos Capes, Biblioteca Virtual em Saúde e Pubmed. Foram incluídos 57 artigos publicados no período de 2005 a 2019 que apresentavam conteúdos compatíveis com os objetivos deste estudo. Resultados: A obesidade está entre as doenças que mais crescem no mundo, o tratamento é inadequado e os distúrbios associados, incluindo câncer gástrico, apresentam alta morbimortalidade. A obesidade pode afetar a microbiota intestinal resultando em uma disbiose, através da interação entre fatores nutricionais, endócrinos e metabólicos, que contribuem por ativar um processo de inflamação crônica de baixo grau levando ao aumento da proliferação celular e angiogênese e diminuição da apoptose celular, culminando no desenvolvimento de câncer gástrico. Dessa forma, é importante ressaltar que o tecido adiposo responde à estimulação de nutrientes extras via hiperplasia e hipertrofia de adipócitos. Com a hipertrofia dos adipócitos, o tecido adiposo torna-se hipoperfundido, o que cria áreas de microhipóxia, ativando as vias do fator de transcrição nuclear NFkB, aumentando a expressão de genes envolvidos na inflamação com maior liberação de citocinas. Assim, níveis elevados de adiponectina e leptina, esteroides sexuais, glicocorticoides, mediadores inflamatórios e fatores de crescimento semelhantes à insulina, podem resultar em estresse oxidativo tecidual e na transformação neoplásica das células gástricas. Conclusão: É necessário um maior entendimento dos mecanismos da carcinogênese induzida pela obesidade para desenvolver métodos mais eficazes para prevenir ou tratar o câncer gástrico. Uma maior compreensão dos mecanismos moleculares pode levar à identificação de novos alvos terapêuticos. Faz-se necessário estudos adicionais sobre os mecanismos envolvidos na carcinogênese gástrica, pois essa doença ainda apresenta altas taxas de morbimortalidade.pt_BR
