目的:先探索白介素-16(IL-16)基因多态性与肿瘤易感性的关系。方法:通过计算机检索和手工检索,收集有关IL-16基因多态性与肿瘤易感性关系的文献,筛选出符合条件的文献,应用 Meta 分析软件对各项研究进行异质性检验,计算合并OR 值及其95%可信区间,并行敏感性分析和发表偏倚的评估。结果:共有6篇文献纳入本研究(肿瘤例数1678;对照例数2417), Meta 分析结果显示 IL-16与肿瘤易感性的关系:rs11556218(G vs. T:OR =1.41,95%CI 1.13~1.77;GG vs. TT:OR =1.21,95%CI 0.89~1.64;GT vs. TT:OR =1.65,95%CI 1.42~1.91;GG/GT vs. TT:OR =1.60,95%CI 1.39~1.85;GG vs. TT/TG:OR =0.93,95%CI 0.70~1.24);rs4072111(T vs. C:OR =1.00,95%CI 0.88~1.13;TT vs. CC:OR =1.04,95%CI 0.72~1.49;CT vs. CC:OR =0.97,95%CI 0.84~1.13;TT/TC vs. CC:OR =0.98,95%CI 0.85~1.14;TT vs. CC/CT:OR =1.06,95%CI 0.74~1.51);rs4778889(C vs. T:OR =1.04,95%CI 0.80~1.35;CC vs. TT:OR =0.77,95%CI 0.49~1.22;CT vs. TT:OR =0.95,95%CI 0.77~1.18;CC/CT vs. TT:OR =0.93,95%CI 0.75~1.16;CC vs. CT/TT:OR =0.75,95%CI 0.55~1.02)。通过肿瘤类型的分层分析,在 IL-16 rs11556218基因多态性中与TT相比较,GT或GG/GT能增加鼻咽癌(OR =1.74,95%CI 1.28~2.37;OR =1.73,95%CI 1.28~2.34)和结直肠癌(OR =1.86,95%CI 1.49~2.32;OR =1.76,95%CI 1.41~2.18)的风险。结论:IL-16 rs11556218基因多态性中GT或GG/GT基因型可增加患肿瘤的风险。
