摘要
目的探讨p53、p57Kip2和CD68蛋白在食管鳞癌组织中的表达及其与食管鳞癌生物学行为的关系。方法应用免疫组化SP法检测51例食管鳞癌组织中p53、p57Kip2和CD68蛋白的表达,并分析3种蛋白表达之间及其分别与临床病理特征之间的关系。结果食管鳞癌组织中p53、p57Kip2和CD68的阳性表达率分别为64.71%、45.09%和58.82%;p53和CD68表达与分化程度、淋巴结转移及TNM分期有关(P<0.05);p57Kip2的阳性表达与分化程度和淋巴结转移有关(P<0.05),与TNM分期无关(P>0.05)。p53阳性表达者的p57Kip2阳性表达率为24.24%,明显低于p53阴性表达者的83.33%(P<0.05);CD68阳性表达者的p57Kip2阳性表达率为20.00%,亦明显低于p53阴性表达者的80.95%(P<0.05)。结论 p57Kip2与CD68、p53在食管鳞癌中的表达呈负相关,3项指标联合检查有助于判断患者的预后。
Objective To investigate the expressions of p53, p57Kip2 and CD68 in esophageal squamous cell carcinoma and their correlation with the biological behavior of esophageal squamous cell carcinoma. Methods The protein expressions of p53, p57KiP2and CD68 were detected in 51 cases of esophageal squamous cell carcinoma with SP immunohistochemical method. Results The positive rates of p53, p57KiP2 and CD68 were 64. 71% , 45.09% and 58.82% respectively in esophageal squamous cell carcino- ma. The positive expressions of p53 and CD68 were related to differentiation and TNM staging of esophageal squamous cell carcinoma, but p57 Kip2 was not related to TNM staging(P 〉 0. 05 ). The positive expression rate of p57Ki~ was significantly lower in the positive p53 of esophageal squamous cell carcinoma than that in the negative (P 〈 0. 05 ). The positive expression rate of p57Kip2 was significantly lower in the positive CD68 of esophageal squamous cell carcinoma than that in the negative ( P 〈 0.05 ). Conclusion There are sig- nificant negative correlations between p57Kip2 and p53 ,CD68 protein expression. Combined detection of three proteins has an important value in prediction of prognosis.
