摘要
目的研究受体相互作用蛋白(RIP)2在直肠癌及癌旁组织中的表达及其与临床病理特征关系。方法直肠癌手术病人77例。使用免疫组化检测直肠癌组织及癌旁组织中RIP2的表达情况。观察以下指标:(1)RIP2在直肠癌组织和癌旁组织中的表达。(2)直肠癌组织中RIP2的表达与临床病理特征的关系。结果 77例直肠癌组织中,RIP2的阳性表达率为57.1%(44/77),癌旁组织为64.9%(50/77),两者比较,差异无统计学意义(P>0.05)。在44例直肠癌组织阳性表达的病人中,低+未分化、Ⅲ+Ⅳ期、合并淋巴结转移、脉管侵犯组的RIP2的阳性表达率高于高+中分化、Ⅰ+Ⅱ期、无淋巴结转移、无脉管侵犯组,差异有统计学意义(P<0.05),而RIP2阳性表达率与性别、年龄、肿瘤直径及有无神经侵犯无关(P>0.05)。免疫组化结果半定量分析显示,直肠癌组织中RIP2的表达较癌旁组织增加,差异有统计学意义(P<0.05)。结论 RIP2在直肠癌组织中表达增强,可能是直肠癌病人预后一个潜在判断指标。
Objective To investigate the expressions of Receptor-interacting protein 2(RIP2)in tissues of rectal cancer(RC)and adjacent tissues,and the relationship with the clinicopathologic factors of RC.MethodsThe clinicopathological data of 77 patients with rectal?cancer who admitted to the Renmin Hospital of Wuhan University from January 2016 to January 2017 were collected.The expressions of RIP2 in cancer and adjacent tissues were detected using immunohistochemical assay.Semi-quantitative data of immunohistochemical assay was analyzed within independent T test.The relationship between the expression of RIP2 and clinicopathologic factors was then analyzed within the chi-square test.Results In these 77 cancer cases,RIP2 is positively expressed in 44 samples,accounted for 57.1%,and 50 cases in adjacent tissues,totally accounted for 64.9%.The difference is not statistically significant(χ~2 =0.983,P>0.05).The positive expression rate of RIP2 in poorly differentiated and undifferentiated cases,stage Ⅲ and stage Ⅳ cases,cases with lymph node metastasis and cases with vein invasion was higher than that in cases of high and middle differentiation,stageⅠand stageⅡ,no lymph node metastasis and no vein invasion(P<0.05).However,the positive expression of RIP2 has nothing with sex,age and tumor size(P>0.05).Besides,semi-quantitative analysis shows that the expression of RIP1 and RIP3 in rectal cancer is less than normal tissue(t=-4.305,P<0.05).Conclusion The expression of RIP2 in rectal cancer is up regulated,and may be a potential reference designator to judge the prognosis of patients with rectal cancer.
