| 1 | Interleukin-10 gene polymorphisms and hepatocellular carcinoma susceptibility:A meta-analysis显示文摘AIM: To assess the association between Interleu-kin-10 (IL-10) gene IL-10-1082 (G/A), IL-10-592(C/A), IL-10-819 (T/C) polymorphisms and hepatocellular carcinoma (HCC) susceptibility.METHODS: Two investigators independently searched the Medline, Embase, China National Knowledge Infrastructure, and Chinese Biomedicine Database. Summary odds ratios (ORs) and 95% conf idence intervals (95% CIs) for IL-10 polymorphisms and HCC were cal-culated in a fixed-effects model (the Mantel-Haenszel method) and a random-effects model (the DerSimonian and Laird method) when appropriate. RESULTS: This meta analysis included seven eligiblestudies, which included 1012 HCC cases and 2308 controls. Overall, IL-10-1082 G/A polymorphism was not associated with the risk of HCC (AA vs AG + GG, OR = 1.11, 95% CI = 0.90-1.37). When stratifying for ethnicity, the results were similar (Asian, OR = 1.12, 95% CI = 0.87-1.44; non-Asian, OR = 1.10, 95% CI = 0.75-1.60). In the overall analysis, the IL-10 polymorphism at position -592 (C/A) was identified as a genetic risk factor for HCC among Asians; patients carrying the IL-10-592*C allele had an increased risk of HCC (OR = 1.29, 95% CI = 1.12-1.49). No association was observed between the IL-10-819 T/C polymorphism and HCC susceptibility (TT vs TC + CC, OR = 1.02, 95% CI = 0.79-1.32).CONCLUSION: This meta-analysis suggests that IL-10-592 A/C polymorphism may be associated with HCC among Asians. IL-10-1082 G/A and IL-10-819 T/C polymorphisms were not detected to be related to the risk for HCC. | Yong-Gang Wei, Fei Liu, Bo Li, Xi Chen, Yu Ma, Lv-Nan Yan, Tian-Fu Wen, Ming-Qing Xu, Wen-Tao Wang, Jia-Yin YangYong-Gang Wei, Fei Liu, Bo Li, Xi Chen, Yu Ma, Lv-Nan Yan, Tian-Fu Wen, Ming-Qing Xu, Wen-Tao Wang, Jia-Yin Yang, Department of Liver and Vascular Surgery, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Prov- ince, China Author contributions: Wei YG and Liu F designed the study, collected and analyzed the data and wrote the manuscript Li B collected and analyzed the data and wrote the manuscript Chen X and Ma Y collected and analyzed the data Yan LN analyzed the data and contributed to the discussion Wen TF and Xu MQ revised the manuscript Wang WT and Yang JY contributed to the discussion Wei YG and Liu F contributed equally to this work. | 2011 | World Journal of Gastroenterology2011，17，34： | 3 |
