摘要
目的观察表皮生长因子(EGF)61*G/A、转化生长因子-β1(TGF-β1)-509*TIC、血管内皮生长因子(VEGF)936*T/C基因功能多态性对术后结肠吻合口瘘的影响。方法采用聚合酶链反应-限制性片段长度多态性(PCR—RFLP)方法检测伴有和不伴有术后结肠吻合口瘘结直肠癌患者的EGF 61*G/A,TGF-β1—509*T/C,VEGF 936*T/C基因型。结果伴有术后结肠吻合口瘘的结直肠癌患者TGF-β1-509*T/T基因型比例(0.0%)低于无术后吻合口瘘的患者(15.2%),两者差异有统计学意义(P〈0.05)。伴有术后结肠吻合口瘘的VEGF 936*C/C基因型和C等位基因比例(65.9%和80.6%)低于无术后吻合口瘘的患者(82.6%和90.5%),两者差异有统计学意义(基因型x^2=5.755,P〈0.05;等位基因x^2=5.275,P〈0.05)。伴有术后结肠吻合口瘘的结直肠癌患者EGF 61*G/G基因型比例(25.0%)低于无术后吻合口瘘的患者(55.5%),但两者差异无统计学意义(x^2=1.591,P〉0.05)。结论TGF-β1-509*T/T基因型,VEGF 936*C/C基因型或936*C等位基因有助于减少术后结肠吻合口瘘的发生。
Objective To understand the effect of EGF,TGF-β1 ,VEGF on the anastomotic leakage after colorectal cancer surgery by the investigation of EGF 61 * G/A,TGF-β1 -509 * T/C ,VEGF 936 * T/C gene functional polymorphism. Methods PCR-RFLP was employed to study the EGF 61 * G/A, TGF-β1 -509 * T/C ,VEGF 936 * T/C genotypes in colorectal cancer patients with or without anastomotic leakage after surgery. Results The frequency of TGF-β1 -509 * T/T genotype in colorectal cancer patients with anastomotic leakage (0.0) was significantly lower than that in the patients without anastomotic leakage ( 13.2% ) ( P 〈 0.05 ). The frequency of VEGF 936 * C/C genotype and C allele in colorectal cancer patients with anastomotic leakage (63.9% and 80.6% respectively) was significantly lower than in the patients without anastomotic leakage (82.6% and 90.5% respectively) (genotypex2 = 5. 753 ,P 〈 0.05 ; allele x^2 = 5. 275, P 〈 0.05 ). Although the EGF 61 * G/G genotype in colorectal cancer patients with anastomotic leakage (25.0%) was less frequently found than in the patients without anastomotic leakage ( 35.5% ), there was no statistically significant difference (x^2 = 1. 391 ,P 〉 0.05 ). Conclusion TGF-β1 -509 * T/T genotype, VEGF 936 * C/C genotype and C allele decrease the risk of anastomotic leakage after surgery for colorectal cancer.
