摘要 应用免疫组化SP法检测cyclinD1和p16在50例胃癌和24例慢性胃炎中的表达。结果:50例胃癌中,cyclinD1的阳性表达率为64%(32/50),p16蛋白的阳性表达率为44%(22/50)。24例慢性胃炎中,cyclinD1的表达率为0,p16的表达率为100%。高分化腺癌中cyclinD1的过表达率为38.5%(5/13),低分化腺癌中为90.9%(20/22),两者差异显著(P<0.0.1);有淋巴结转移组的cyclinD1过表达率为73.1%(19/26),无淋巴结转移组为54.1%(13/24),两者无显著性差异(P>0.05)。高分化腺癌中p16的表达率为76.9%(10/13),低分化腺癌为27.3%(6/22),两者差异显著(P<0.01);有淋巴结转移组的p16的表达率为30.8%(8/26),无淋巴结转移组的为58.3%(14/24),两者有差异(P<0.05)。认为cyclinD1的过表达和p16的缺失两者可能共同参与了胃癌的发生发展过程,cyclinD1和p16作为反映胃癌病理学特点的参考指标有一定的临床意义。
