目的：探讨胃肝样腺癌及普通型胃癌ｐ２１基因蛋白产物表达情况，进一步判断肿瘤的恶性程度。方法：应用免疫组化ＡＢＣ法，对２８例胃肝样腺癌进行检测。结果：２８例胃肝样腺癌ｐ２１基因表达阳性率９６．４％，其中染索状１８例，团块状１０例。其阳性表达明显高于普通型胃癌。结论：检查胃肝样腺癌ｐ２１基因蛋白产物表达，为临床治疗及判断预后提供重要依据
Objective: To investigate the expression of p21 gene protein in gastric adenocarcinoma of gastric and hepatocellular carcinoma and to evaluate the malignant degree of tumor. Methods: Using immunohistochemical ABC method, 28 cases of gastric adenocarcinoma were detected. Results: The positive rate of p21 gene expression was 96.4% in 28 cases of gastric adenocarcinoma, including 18 cases of stained cord and 10 cases of clumps. The positive expression was significantly higher than ordinary gastric cancer. Conclusion: The expression of p21 gene protein in gastric adenocarcinoma of the stomach and the liver can be analyzed. It provides an important basis for clinical treatment and prognosis
