摘要： 目的 探讨衰变加速因子(decay-accelerating factor,DAF)基因rs150046210多态性与结直肠癌发病的关系。 方法 收集来自唐山市工人医院的380例结肠癌病人和380例正常对照及450例直肠癌病人和450例正常对照的资料及血液样本,采用PCR凝胶电泳对DAF rs150046210进行基因分型。采用非条件Logistic回归分析DAF rs150046210变异与结直肠癌发病风险的关系。 结果 与DAF rs150046210 DD基因型携带者相比,Ⅱ基因型携带者结、直肠癌发病风险分别增加0.764倍(95%CI:1.763~2.675,P=0.008)、0.789倍(95%CI:1.227~2.608,P=0.003)。性别分层中,与DAF rs150046210 DD基因型携带者相比,携带Ⅱ基因型的女性患结肠癌风险增加1.015倍(95%CI:1.085~3.742,P=0.026),携带Ⅱ基因型的男性患直肠癌风险增加1.041倍(95%CI:1.290~3.228,P=0.002);年龄分层中,与DAF rs150046210 DD基因型携带者相比,携带Ⅱ基因型的低年龄组(≤60岁)患结肠癌风险增加(OR=2.335, 95%CI:1.273~4.356,P=0.006),携带DI、Ⅱ基因型的高年龄组患直肠癌风险也增加(OR=1.757,95%CI:1.106～2.789,P=0.017;OR=2.313, 95%CI:1.334~4.012,P=0.003)。与DAF rs150046210 DD基因型携带者相比,携带Ⅱ基因型的不吸烟、不饮酒者患结肠癌风险分别增加0.791倍(95%CI:1.106~2.900,P=0.018)、0.714倍(95%CI:1.086~2.704,P=0.021),携带Ⅱ基因型的不吸烟、不饮酒者患直肠癌风险分别增加1.395倍(95%CI:1.514~3.788,P<0.001)、0.923倍(95%CI:1.221~3.030,P=0.005)。结论 DAF rs150046210多态性可能增加老年人结直肠癌发病风险。

Abstract: Objective To explore the association of genetic variants of decay-accelerating factor (DAF)rs150046210 with the risk of colorectal cancer. Methods DAF rs150046210 was genotyped by Polymerase Chain Reaction in 380 patients with colon cancer and 380 normal controls, 450 patients with rectal cancer and 450 normal controls, respectively. Logistic regression was used to investigate the association between rs150046210 and colorectal. Results Compared with DAF rs150046210 DD genotype carriers,Ⅱ genotype carriers had 0.764 times (95%CI: 1.763-2.675, P=0.008) and 0.789 times (95%CI: 1.227-2.608, P=0.003) higher risk of colon cancer and rectal cancer, respectively. When stratified by sex, women with genotype Ⅱ had a 1.015-fold increased risk of colon cancer (95%CI: 1.085-3.742, P=0.026), and men with genotype Ⅱ had a 1.041-fold increased risk of rectal cancer (95%CI: 1.290-3.228, P=0.002),comparing with DAF rs150046210 DD carriers. In the age stratification, this genetic variation affected the risk of colon cancer (OR=2.355, 95%CI: 1.273-4.356,P=0.006) in the low age group (≤60 years old) who carried Ⅱ gene, also affected the risk of rectal cancer (OR=1.757,95%CI:1.106-2.789,P=0.017),(OR=2.313, 95%CI:1.334-4.012,P=0.003) in the high age group (>60 years old) with DI or Ⅱ genotype. Compared with DAF rs150046210 DD genotype carriers, Ⅱ genotype of not smoking, not drinkers had a 0.791(95% CI: 1.106-2.900, P=0.018) and 0.714 (95% CI: 1.086-2.704, P= 0.021)-fold increased risk of colon cancer incidence, type Ⅱ gene carriers who didn′t smoke or drink wine showed increased risk of rectal cancer(OR=2.395, 95%CI:1.514-3.788,OR=1.923, 95%CI: 1.221-3.030, respectively). Conclusions DAF rs150046210 polymorphism can increase the risk of colorectal cancer in the elderly patients.
