摘  要:应用ABC免疫组织化学染色方法检测120例胃癌和大肠癌的癌肿内及转移淋巴结中c-erbB-2、p53、p21基因的过度表达。多基因阳性在胃癌中占66.7%;大肠癌中占68.3%,多基因表达明显提示胃癌及大肠癌预后差。单基因阳性亦分别显示胃癌及大肠癌预后较差。转移淋巴结与胃癌及大肠癌的原发癌肿之间基因过度表达与否的平均符合率c-erbB-2为83.1%;p53为75.3%;p21为77.9%,表明转移淋巴结中的基因过度表达与否与原发癌肿相似。c-erbB-2、p53、p21的多基因表达的检测对胃癌和大肠癌的预后判断明显优于其中某个单基因表达的检测。The overexpression of cerbB2,p53 and p21 in 120 cases of gastric and colorectal cancers and their metastatic lymph nodes were studied immunohistochemically.The multiple gene positive rate in gastric cancer was 66.7% and that in colorectal cancer was 68.3%.The polygene overexpression significantly indicated poor prognosis of gastric and colorectal cancers,just as anyone single gene overexpression.The mean coincident rates of overexpression or nonoverexpression of cerbB2,p53,p21 in metastatic lymph nodes and the primary gastric and colorectal cancers were 83.1%,75.3% and 77.9% respectively which means that overexpression in metastatic lymph nodes paralleled that in the primary tumors.Determination of overexpression of cerbB2,p53 and p21 simultaneously was superior that of any one gene singly in evaluating the prognosis of gastric and colorectal cancers.
