FHIT及DCP4的表达与胃癌进展及淋巴转移的关系

目的探讨脆性组氨酸三联体(FHIT)和胰腺癌缺失因子4(DCP4)的表达与胃癌进展及淋巴结转移的关系。方法 82例胃癌组织标本应用免疫组织化学染色SP法,检测DCP4和FHIT的表达,分析与胃癌病理的分级、临床分期、淋巴结转移的关系。结果 FHIT蛋白在胃癌组织中阳性表达率下降(47.56%),与对照组比较有显著差异(P<0.05)。FHIT在有淋巴结转移胃癌组织中其阳性降低(34.69%),与无淋巴转移比较差异有显著性(P<0.01)。FHIT在年龄≥60岁阳性表达率增高(57.41%),与年龄<60岁比较差异有显著性(P<0.05)。DCP4蛋白在胃癌组织中阳性表达率下降(42.68%),与对照组比较有显著差异(P<0.01)。DCP4蛋白在有淋巴结转移胃癌组织中其阳性表达率为降低(36.73%),与无淋巴转移比较差异无显著性(P>0.05)。不同病理分级和临床分期的胃癌FHIT和DCP4表达PI值显著降低,与正常对照组比较差异有显著性(P<0.01)。结论 (1)DCP4和FHIT蛋白表达异常与胃癌临床分期、病理分级、淋巴转移存在一定内在联系,其中FHIT蛋白表达异常与年龄有一定关系;(2)抑癌基因DCP4和FHIT高表达与胃癌进展及淋巴结转移的有关。

Relationship of DCP4 and FHIT expression with the progression and lymph node metastasis of gastric cancers

Aim To study the relationship of fragile histidine triad(FHIT)and in similar to mothers against decapentaplegic homolog-4(DCP4)expression with the progression and lymph node metastasis of gastric cancers.Methods Expression of FHIT and DCP4,in 82 cases of gastric cancers tissues,were determined with immuno-histochemistry method(SP)to analyze the relations between FHIT and DCP4 expressions and pathological classifications and clinical stages in gastric cancer.Results The positive rate of FHIT and DCP4 protein...
