胃癌P_(53)蛋白和雌孕激素受体的表达及意义

应用LSAB免疫组化法和酶联亲和组化法对41例胃癌P53蛋白和雌激素受体（ER）、孕激素受体（PR）的表达进行研究。结果显示：胃癌中P53蛋白、ER、PR的阳性率分别为41．46％、21．95％、14．63％。P53蛋白表达与肿瘤组织学分级、浸润汉度、临床分期及淋巴结转移呈正相关，与ER、PR表达呈负相关。在ER、PR阴性者中P53蛋白阳性中高于ER、PR阳性者。P53蛋白表达与组织学类型无关。提示检测P53蛋白、ER、PR的表达，可作为判断胃癌细胞增殖程度、转移潜能及预后和内分泌治疗有效率的重要参考指标。     

P_(53)蛋白和增殖细胞核抗原在肾癌中表达的临床意义

采用免疫组织化学方法检测40例肾癌组织中P53蛋白和增殖细胞核抗原（PC-NA）的表达。发现P53蛋白阳性表达者共10例（25％）。P53蛋白表达与肿瘤病理分级、临床分期及预后无相关性。肾癌组织的PCNA增殖指数随肿瘤病理分级的上升而增加，PC－NA高表达组（增殖指数＞10％）预后不良，特别是临床早期但PCNA高表达者预后也很差。结果提示P53蛋白表达在肾癌生物学行为及预后评估中无重要意义，而PCNA可作为肾癌恶性度及预后评估指标。P53蛋白和PCNA表达无相关性。     

增殖细胞核抗原在胃癌中的表达与淋巴结转移、预后的关系

为探讨增殖细胞核抗原 ( Proliferating cell nuclear antigen,PCNA)在胃癌的表达与淋巴结转移及预后的关系 ,采用免疫组化法 ( ABC法 )测定 94例胃癌石蜡包埋标本。结果 :1胃粘膜不同病理状态下 PCNA指数差异显著 ( P <0 .0 1 ) ;2PCNA指数同患者的性别和年龄无关 ( P >0 .0 5 ) ,与肿瘤的生长方式、组织类型、浆膜层受侵与否、淋巴结转移与否和临床分期关系密切 ( P <0 .0 5 ) ;3PCNA指数与胃癌的预后密切相关 ( P <0 .0 5 ) ,弱级 ( 1～ 2级 )表达的患者预后较好 ,提示 PCNA检测可作为判断胃癌生物学行为和预后的一项良好指标。

P~(53)蛋白和PCNA在恶性纤维组织细胞瘤中的表达与预后的关系

为探讨恶性纤维组织细胞瘤（Ｍａｌｉｇｎａｎｔｆｉｂｒｏｕｓｈｉｓｔｉｏｃｙｔｏｍａ,ＭＦＨ）中Ｐ５３蛋白和增殖细胞核抗原（Ｐｒｏｌｉｆｅｒａｔｉｎｇｃｅｌｎｕｃｌｅａｒａｎｔｉｇｅｎ,ＰＣＮＡ）的表达强度与预后的关系,应用免疫组化ＬＳＡＢ法及彩色图像分析系统定量检测了４６例ＭＦＨ细胞中Ｐ５３蛋白和ＰＣＮＡ的表达强度。结果显示ＭＦＨ的Ｐ５３蛋白与ＰＣＮＡ表达间呈正相关,Ｐ５３蛋白阳性表达组ＰＣＮＡ的表达强度高于Ｐ５３蛋白阴性表达组（Ｐ＜０．０５）。Ｐ５３蛋白表达阳性和ＰＣＮＡ表达强度值高组较Ｐ５３表达阴性和ＰＣＮＡ表达强度值低组的生存期短、肿瘤转移率高、组织学分级高（Ｐ＜０．０５）;肿瘤位置深在组Ｐ５３蛋白和ＰＣＮＡ表达强度高于肿瘤位置浅表组（Ｐ＜０．０５）。结果提示定量检测ＭＦＨ的Ｐ５３蛋白和ＰＣＮＡ对于评估ＭＦＨ患者的预后具有较可靠的应用价值。
