ABSTRACT
ABSTRACT

BACKGROUND:

The role of -251A>T polymorphism in the anti-inflammatory cytokine interleukin-8 (IL-8) gene in gastric cancer was intensively evaluated, but the results of these studies were inconsistent.

OBJECTIVE:

Therefore, we performed a meta-analysis to provide a comprehensive data on the association of IL-8 -251T>A polymorphism with gastric cancer.

METHODS:

All eligible studies were identified in PubMed, Web of Science, EMBASE, Wanfang and CNKI databases before September 01, 2019. The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were derived from a fixed effect or random effect model.

RESULTS:

A total of 33 case-control studies with 6,192 cases and 9,567 controls were selected. Overall, pooled data showed that IL-8 -251T>A polymorphism was significantly associated with an increased risk of gastric cancer under all five genetic models, i.e., allele (A vs T OR=1.189, 95% CI 1.027-1.378, P=0.021), homozygote (AA vs TT OR=1.307, 95% CI 1.111-1.536, P=0.001), heterozygote (AT vs TT OR=1.188, 95% CI 1.061-1.330, P=0.003), dominant (AA+AT vs TT OR=1.337, 95% CI 1.115-1.602, P=0.002) and recessive (AA vs AT+TT OR=1.241, 95% CI 1.045-1.474, P=0.014). The stratified analysis by ethnicity revealed an increased risk of gastric cancer in Asians and mixed populations, but not in Caucasians. Moreover, stratified by country found a significant association in Chinese, Korean and Brazilian, but not among Japanese.

CONCLUSION:

This meta-analysis suggests that the IL-8 -251T>A polymorphism is associated with an increased risk of gastric cancer, especially by ethnicity (Asian and mixed populations) and country (Chinese, Korean and Brazilian).
RESUMO
RESUMO

CONTEXTO:

O papel do polimorfismo -251A>T no gene anti-inflamatório citocina interleucina-8 (IL-8) no câncer gástrico foi intensamente avaliado, mas os resultados desses estudos foram inconsistentes.

OBJETIVO:

Portanto, realizamos uma meta-análise para fornecer dados abrangentes sobre a associação de IL-8 -251T>A polimorfismo com câncer gástrico.

MÉTODOS:

Todos os estudos elegíveis foram identificados nos bancos de dados PubMed, Web of Science, EMBASE, Wanfang e CNKI antes de 01 de setembro de 2019. As relações de probabilidades agrupadas (ORs) com intervalos de confiança de 95% (IC) foram derivadas de um modelo de efeito fixo ou efeito aleatório.

RESULTADOS:

Foram selecionados 33 estudos de controle de caso com 6.192 casos e 9.567 controles. No geral, dados agrupados mostraram que o polimorfismo IL-8 -251T>A foi significativamente associado a um risco aumentado de câncer gástrico em todos os cinco modelos genéticos, isto é, alelo (A vs T OR=1,189; 95% CI 1,027-1,378; P=0,021), homozigoto (AA vs TT OR=1,307; 95% CI 1,111-1,536; P=0,001), heterozigoto (AT vs TT OR=1,188; 95% CI 1,061-1,330; P=0,003), dominante (AA+AT vs TT OR=1,337; 95% CI 1,115-1,602; P=0,002) e recessivo (AA vs AT+TT OR=1,241; 95% CI 1,045-1,474; P=0,014). A análise estratificada por etnia revelou um risco aumentado de câncer gástrico em asiáticos e populações mistas, mas não em caucasianos. Além disso, estratificado por país. Encontrou-se uma associação significativa em chineses, coreanos e brasileiros, mas não entre os japoneses.

CONCLUSÃO:

Esta meta-análise sugere que o polimorfismo IL-8 -251T>A está associado a um risco aumentado de câncer gástrico, especialmente por etnia (populações asiáticas e mistas) e por país (chinês, coreano e brasileiro).
