چکیده
PURPOSE The association between Interleukin-17A (IL- 17A) G197A and IL-17F T7488C polymorphisms and risk for specific forms of cancer is inconclusive. We conducted a meta-analysis of all published studies to estimate the association of IL-17A G197A and IL-17F T7488C polymorphisms and cancer risk. METHODS A systematic computerized searching of the PubMed and Web of Science databases was performed for relevant publications. Data were extracted and statistical analysis was performed using RevMan 5.2 software. RESULTS Eight eligible case-control studies with 3,323 cases and 3,974 controls were included into this meta-analysis. The pooled odds ratios (ORs) showed that the IL-17A G197A polymorphism increased the risk for specific forms of cancer under the following genetic models: A vs G (OR = 1.31, 95 % CI 1.13-1.52, Ph - 0.02); AA vs GG (OR = 1.81, 95 % CI 1.30- 2.52, Ph = 0.007); AA /AG vs GG (OR = 1.26, 95 % CI 1.11- 1.43, Ph = 0.79); AA vs AG / GG (OR = 1.72, 95 % CI 1.16-2.53, Ph <0.0001). However, the IL-17F T7488C polymorphism did not increase or decrease cancer risk under all genetic models. Stratified analysis by cancer type revealed that the IL-17A G197A polymorphism may increase the risk of gastric cancer. Further subgroup analysis by country indicated that there was a statistically increased cancer risk in China. CONCLUSIONS The present meta-analysis showed the IL- 17A G197A polymorphism is associated with a significantly increased risk for specific forms of cancer, especially in gastric cancer. Subsequent studies with large sample size are warranted to validate this association.

Role of IL-17A rs2275913 and IL-17F rs763780 polymorphisms in risk of cancer development: an updated meta-analysis
Single nucleotide polymorphisms (SNPs) in the interleukin-17 (IL-17) gene have been shown to be correlated with susceptibility to cancer. However, various studies report different results of this association. The aim of the present work was to clarify the effects of IL-17A G197A (rs2275913) and IL-17F T7488C (rs763780) polymorphisms on cancer risk. We performed systematic searches of the PubMed...
متن کاملIL-17A (-197G/A) and IL-17F (7488T/C) gene polymorphisms and cancer risk in Asian population: a meta-analysis
Interleukin (IL)-17 has been shown to play an important role in the pathogenesis of inflammation and cancer. The IL-17A (-197G/A) and IL-17F (7488T/C) polymorphisms have been extensively investigated with cancer risk, but individually published results have been inconclusive. The aim of this study was to clarify the effects of the IL-17A (-197G/A) and IL-17F (7488T/C) polymorphisms on cancer ri...
متن کاملIL-17A G197A gene polymorphism contributes to susceptibility for liver cirrhosis development from patients with chronic hepatitis B infection in Chinese population.
BACKGROUND IL-17A G197A and IL-17F A7488G gene polymorphisms are found to be associated with the risk of several diseases, however few studies have focused on their correlation with risk of liver cirrhosis (LC). AIMS The aim of this study was to assess the impact of IL-17A G197A and IL-17F A7488G gene polymorphisms on development of LC from chronic hepatitis B (CHB) in Chinese patients. MET...

BACKGROUND Interleukin-17 (IL-17) is a family of emerged pro-inflammatory cytokines. The IL-17A and IL-17F are two important members of IL-17 family. Previous studies have shown that the functional IL-17A G-197A and IL-17F 7488T/C polymorphisms may contribute to susceptibility to cancer but the results were inconclusive. This meta-analysis was performed to determine the exact association betwee...
