摘要
目的探讨胃癌组织中ERCC1与AKT1的表达及不同病理分期术后胃癌中ERCC1、AKT1表达与PFS的关系。方法用RT-PCR方法检测51例胃癌组织与癌旁组织的ERCC1与AKT1的表达,观察预后,并进行统计分析。结果胃癌组织中ERCC1、AKT1的阳性表达率分别为61%、71%,ERCC1、AKT1在癌旁组织中表达率高于癌组织,ERCC1、AKT1在淋巴结有无转移之间表达有统计学差异。ERCC1、AKT1阳性者Ⅰ期预后好于阴性者,在Ⅱ-Ⅳ期表达阳性者预后差。结论AKT1、ERCC1在癌旁组织中阳性表达率高于癌组织,ERCC1、AKT1在Ⅰ期胃癌术后表达阳性者预后好,而Ⅱ-Ⅳ期相反。
Objective To study expression of ERCC1 and AKT1 in gastric cancer tissues and to analyze the relationship between expression and PFS.Methods 51 cases of expressions of ERCC1 and AKT1 in gastric cancer tissues and adjacent normal tissues were detected by RT-PCR.The prognosis was observed and statistically analyzed.Result In 51 cases,the ERCC1(+) was 61% and AKT1(+) was 71%.The positive expressive rates of ERCC1 and AKT1 were higher in adjacent normal tissues than in gastric adenocarcinoma tissues.There was statistical difference in expressions of ERCC1 and AKT1 with or without lymph node metastasis.The prognosis of patients of ERCC1(+) and AKT1(+)was better in stage Ⅰ,while poor in stages Ⅰ-Ⅳ.Conclusion The positive expressive rates of ERCC1 and AKT1 in adjacent normal gastric cancer are higher than in gastric tissues.The prognosis of ERCC1(+) and AKT1(+) is better in stage Ⅰ,but poor in stages Ⅱ-Ⅳ.
