摘要 目的观察免疫标记CD44v6和增殖细胞核抗原(PCNA)在宫颈癌组织中的袁达,并探讨其临床意义。方法采用免疫组织化学方法检测63例宫颈鳞癌,10例正常宫颈组织中CD44v6和PCNA的表达。结果CD44v6表达在正常宫颈组织、宫颈鳞癌Ⅰb、宫颈鳞癌Ⅱa、宫颈鳞癌Ⅱb、高分化鳞癌、低分化鳞癌、有淋巴结转移和无淋巴结转移的鳞癌组织中的阳性表达率分别为0、41.2%、61.1%、55.0%、35.9%、75.0%、80.7%和40.5%,CD44v6在宫颈鳞癌的不同临床分期中的表达比较差异无统计学意义(P〉0.05),CD44v6在高分化和低分化宫颈鳞癌和有无淋巴结转移病例中的阳性表达率比较差异有统计学意义(P〈0.05);CD44v6在正常宫颈组织与宫颈鳞癌组织中表达比较差异有统计学意义(P〈0.01);PCNA表达在正常宫颈组织、宫颈鳞癌Ⅰb、宫颈鳞癌Ⅱa、宫颈鳞癌Ⅱb、高分化鳞癌、低分化鳞癌、有淋巴结转移和无淋巴结转移的鳞癌组织中表达阳性率分别为10.0%、52.9%、55.5%、100%、51.3%、100%、100%和48.6%。PCNA在宫颈鳞癌的几个不同临床分期病例组间表达阳性率比较差异有统计学意义(P〈0.05);宫颈鳞癌的高分化组和低分化组、有淋巴结转移组与无淋巴结转移组PCNA阳性表达率比较差异均有统计学意义(P〈0.05)。结论CIM4v6与宫颈鳞癌的临床分期无关,与宫颈鳞癌的组织学分级和有无淋巴结转移有关;PCNA与宫颈鳞癌的,临床分期、组织学分级和有无淋巴结转移有关,二者共同标记对于正确评估宫颈鳞癌的临床分期与判断预后有较重要意义。
