To investigate the association of the IL-6 -572C > G polymorphism with the risk of prostate cancer (PCa) in the Chinese Han population in Jiangsu and Anhui area.
We obtained peripheral blood genome DNA from 200 PCa patients and 279 age-matched PCa-free healthy controls, analyzed the site polymorphism of IL-6 -572C > G with the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique, and studied the correlation of different genotypes with the susceptibility to PCa.
The subjects that carried the CCGG genotype had a risk of PCa 2.46 times that of the CC genotype carriers (95% CI = 1.41-4.29), and 2.47 times that of the CC/GC genotype carriers (95% CI = 1.47-4.17). This risk was significantly increased among the following subgroups of CCGG genotype carriers: age > 70 yr (OR = 3.06, 95% CI: 1.44-6.49), BMI > 23 kg/m2 (OR = 3.72, 95% CI: 1.79-7.74), no cigarette smoking (OR = 2.96, 95% CI: 1.30-6.72), alcohol drinking (OR = 2.73, 95% CI: 1.28-5.79), with a family history of cancer (OR = 6.67, 95% CI: 1.50-29.69).
In the Chinese Han population in Jiangsu and Anhui area, IL-6 -572C > G polymorphism is associated with the susceptibility to PCa, and GG might be a susceptible genotype to PCa.
探讨白细胞介素-6（IL-6）-572C＞G基因多态性与江苏和安徽地区中国汉族人群前列腺癌（PCa）风险的相关性。
我们从200例PCa患者和279例年龄匹配的无PCa健康对照者中获取外周血基因组DNA，采用聚合酶链反应-限制性片段长度多态性（PCR-RFLP）技术分析IL-6 -572C＞G位点多态性，并研究不同基因型与PCa易感性的相关性。
携带CCGG基因型的受试者患PCa的风险是CC基因型携带者的2.46倍（95%可信区间[CI]=1.41-4.29），是CC/GC基因型携带者的2.47倍（95%CI=1.47-4.17）。在CCGG基因型携带者的以下亚组中，这种风险显著增加：年龄＞70岁（比值比[OR]=3.06，95%CI：1.44-6.49）、体重指数（BMI）＞23kg/m²（OR=3.72，95%CI：1.79-7.74）、不吸烟（OR=2.96，95%CI：1.30-6.72）、饮酒（OR=2.73，95%CI：1.28-5.79）、有癌症家族史（OR=6.67，95%CI：1.50-29.69）。
在江苏和安徽地区的中国汉族人群中，IL-6 -572C＞G基因多态性与PCa易感性相关，GG可能是PCa的易感基因型。
