摘要 目的探讨黏附分子整合素αvβ6与卵巢癌进展及转移的关系. 方法①用免疫组织化学方法检测 5例正常卵巢组织,10例卵巢良性肿瘤,64例卵巢癌中整合素αvβ6的表达,并分析其与临床病理特征间的关系;②用免疫组织化学方法和流式细胞术分别定性和定量分析卵巢癌原发灶及其相应转移灶中的整合素αvβ6表达,并进行比较.结果①整合素αvβ6定位于卵巢癌细胞的胞膜及胞浆中,64例卵巢癌原发灶中有不同程度的表达,其中阳性表达率为 46.88 %(30/64),而正常卵巢和良性卵巢上皮肿瘤不表达.②整合素αvβ6 的表达与年龄、分级、组织学类型无关(P>0.05);早期卵巢癌(FIGOⅡ期)整合素αvβ6阳性表达率为14.29 %,显著低于晚期(FIGOⅢ~Ⅳ期)的 56.00 % (P<0.05);进展期患者阳性表达率为 63.63 %,显著高于无进展患者的 10.00 %(P<0.05).③免疫组织化学结果表明,原发灶中整合素αvβ6阳性表达率为 46.88 %,显著低于转移灶中整合素αvβ6的阳性表达率 71.88 %(P<0.05).④流式细胞术检测原发灶整合素αvβ6的FI值为(1.13±0.14),显著低于转移灶的FI值 (1.98±0.19)(P<0.05).结论整合素αvβ6表达上调与卵巢癌的不良预后和高转移性有关,提示其参与了卵巢癌细胞的侵袭与转移.
