【摘要】 应用ＳＬＡＢ免疫酶标法在石蜡切片上半定量分析增殖细胞核抗原（ＰＣＮＡ）的表达与７３例胃癌患者预后的关系，探讨其临床应用价值。结果表明，以ＰＣＮＡ阳性细胞５０％为界线，阳性率＞５０％者术后生存期较短，５年生存率较低，而淋巴结转移率则较高。提示ＰＣＮＡ检测可作为胃癌预后判断的良好指征。更多还原

【Abstract】 xpression of proliferating cell nuclear antigen (PCNA ) in 73 cases of gastric carcinoma and its relationship to prognosis were semiquantitatively analysed by SLAB immunohis- tochemical method , and its clinical application was explored. The results showed that the . patients with > 50% PCNA positive rate correlated to a decreased survival , but higher rate of lymph node metastasis than that with < 50% positive rate. Our data suggested that PC- NA can be regarded as a significant prognostic indicator in gastric carcinoma.更多还原
