摘 要:[目的] 研究泛素连接酶Hrd1在胃癌组织中的表达及其与胃癌患者临床病理特征及预后的关系。[方法] 收集60例胃癌患者手术切除组织,采用免疫组化SP法检测Hrd1在胃癌组织和癌旁组织中的表达情况。[结果] 60例胃癌患者的组织中有38例Hrd1阳性表达,阳性率为63.3%,在癌旁正常组织中23例Hrd1阳性表达,阳性率为38.3%,在胃癌组织中明显高于癌旁组织(P<0.05)。Hrd1在胃癌组织中的表达与肿瘤的大小、TNM分期有关(P<0.05);而与患者性别、年龄、分化程度及淋巴结转移、肿瘤发生部位等指标无明显相关性(P>0.05)。Hrd1在胃癌组织中的表达与胃癌预后相关(P<0.05)。[结论] Hrd1表达与胃癌发生、发展有关,其在胃癌中的表达情况可以作为判断胃癌预后的参考指标。 |

Abstract:[Purpose] To investigate the expression of Hrd1 in gastric cancer and its clincopathological significance.[Methods] The expression of Hrd1 in 60 samples of gastric carcinoma and adjacent normal tissues was detected by immunohistochemical SP method. [Results] Of 60 cases of patients with gastric cancer tissues,the positive rate of Hrd1 was 63.3%,which was significantly higher than that in adjacent normal tissues(38.3%). The expression of Hrd1 was related to tumor size and clinical stage(P<0.05),but wasn’t related to age,gender,tumor differentiation,lymph metastasis and tumor location(P>0.05). Moreover,correlation was found between expression of Hrd1 and prognosis of gastric cancer(P<0.05). [Conclusions] Hrd1 plays an important role in gastric cancer development. The expression of Hrd1 in gastric carcinoma can be used as a reference index for judging the prognosis of gastric cancer. |
