Ki-67、c-myc、p53在食管癌中的表达及其意义

目的 探讨Ki-67、c-myc、p53在食管癌中的表达及其意义.方法 选取食管癌标本25例、切缘远端正常组织标本25例,采用免疫组织化学法检测组织中Ki-67、c-myc、p53蛋白的表达情况.结果 食管癌组织中Ki-67、c-myc、p53中位表达量分别为5.0、2.0、3.0,明显高于癌旁正常组织的1.0、0.5、0.3（均P＜0.05）.高分化食管癌组织Ki-67中位表达量（3.0）低于中低分化组（6.0）,差异有统计学意义（P＜0.05）.食管癌组织Ki-67与c-myc的表达呈正相关（P＜0.05）.结论 食管癌组织中Ki-67、c-myc、p53高表达,且随分化程度升高而升高,Ki-67、c-myc、p53有望成为食管癌的肿瘤标志物.

Expressions of Ki-67, c-myc and p53 in esophageal cancer and their significance

Objective To investigate the role of Ki-67,c-myc,p53 in human in esophageal cancer.Methods 25 specimens of human esophageal cancer as observe group and 25 adjacent normal specimens as control group were selected.Expressions of Ki-67,c-myc,p53 protein were detected by immunohistochemical staining.Results Protein expressions levels of Ki-67,c-myc and p53 in human esophageal cancer were significantly higher than those in control group 5.0,2.0,3.0 vs 1.0,0.5,0.3,respectively （all P 〈 0.05）.The expression level of Ki-67 protein in high differentiation group were significantly lower than that of moderate and low differentiation group （3.0 vs 6.0,P 〈 0.05）.In human esophageal cancer specimens,the expression level of Ki-67 protein was positively correlated with that of c-myc （P 〈 0.05）.Conclusion The expressions of Ki-67,c-myc and p53 are higher in esophageal cancer,which are increased with the higher differentiation.Ki-67,c-myc and p53 proteins may be taken as potential markers in human esophageal cancer.
