摘要 目的研究增殖指标Ki-67蛋白和p53蛋白在人肝胆管上皮内瘤变及癌变中的表达及其诊断意义。方法运用免疫组织化学S-P方法检测70例肝胆管上皮内瘤变及癌变(低级别肝胆管上皮内瘤变42例,高级别上皮内瘤变28例,高级别中癌变16例)组织中Ki-67蛋白和p53蛋白的表达情况。结果 (1)肝胆管上皮癌变组织中Ki-67的增殖指数为20.65±7.62,明显高于肝胆管上皮内瘤变(P<0.05),并随肝胆管上皮增生程度的增加其增值指数也增高。(2)在16例肝胆管癌变组织中p53蛋白的增值指数为14.73±5.57,明显高于胆管上皮内瘤变组织的蛋白表达(P<0.05)。结论从肝胆管上皮内瘤变到癌变这一发展过程中,Ki-67及p53蛋白增值指数随着细胞增生程度而增高,为临床判断病变程度提供了较具体可靠的参考依据。
