摘    要:目的:探讨Ki-67、p16和p53在结肠癌组织中表达的意义和它们之间的相关性。方法:应用链霉素-生物素(SP)免疫组织化学法,对127例结肠癌进行Ki-67、p16和p53的检测。结果:结肠癌Ki-67、p16和p53蛋白阳性表达率分别为74.8%、47.2%和54.3%。Ki-67蛋白阳性表达均与肿瘤分化程度、浸润深度和淋巴结转移显著相关(P〈0.05),而与患者年龄、肿瘤大体类型无关(P〉0.05);p16蛋白阳性表达与肿瘤分化程度和淋巴结转移显著相关(P〈0.05),与患者年龄,肿瘤大体类型、浸润深度无关(P〉0.05);p53与肿瘤分化程度显著相关(P〈0.05),与患者年龄,肿瘤大体类型、浸润深度和淋巴结转移无关(P〉0.05)。结肠癌中Ki-67蛋白和p16、p53蛋白的表达无显著关系(P〉0.05)。结论:结肠癌中Ki-67表达的上调与其浸润转移密切相关,p16和p53在结肠癌发生发展过程中具有重要作用;术前联合检测Ki-67、p16和p53在结肠癌活检组织中的表达,对指导手术决策,以及估计预后有重要的临床应用价值。

Abstract:Objective:To study the expression of Ki-67, p16 and p53 in colon cancer tissues and their relationship.Methods:Using immunohistochemical method(SP method), the expression of Ki-67, p16 and p53 was detected in 127 cases of colon carcinoma.Results:The positive rates of Ki-67, p16 and p53 were74.8%, 47.2% and 54.3%, respectively. The positive expression of Ki-67 was closely correlated to the differentiation degree,invasive degree and lymph node metastasis (P>0.05) , but it was not correlated to the age and org...
Keywords:Ki-67  p16  p53
