Abstract
摘 要: 【目的】 探讨半乳糖凝集素-3(Galectin-3 Gal-3)和β-Catenin在上皮性卵巢癌组织中的表达情况及临床意义。【方法】 采用免疫组织化学方法,检测77例上皮性卵巢癌患者肿瘤组织中Gal-3和β-Catenin蛋白表达的情况,并分析其与患者临床病理特征、治疗效果及预后的关系。 【结果】 在77例卵巢癌组织中,Gal-3阳性表达率为(70/77)90.9%。β-catenin阳性表达率为(65/77)84.4%。正常卵巢上皮不表达Gal-3和β-Catenin蛋白。Gal-3和β-Catenin的表达常表现为正相关关系,相关系数r = 0.437,P = 0.000。将弱阳性与强阳性合并为阳性后进行统计分析,Gal-3与病理类型相关,β-Catenin与病理类型、是否复发相关,P < 0.05。单因素(Cox回归)分析显示,临床分期(P = 0.019)、复发(P = 0.007)、铂耐药(P = 0.000)及Gal-3表达(P = 0.007)为影响上皮性卵巢癌患者术后总体生存(OS)的因素。多因素分析显示,铂类耐药(HR = 0.233,P = 0.001)与Gal-3表达(HR = 2.325,P = 0.036)与预后明显相关。【结论】 Gal-3和β-Catenin可能与上皮性卵巢癌的发生发展有关,并可作为上皮性卵巢癌预后不良的预测指标,Gal-3可能通过β-Catenin激活经典的Wnt通路,在在上皮性卵巢癌中,发生、发展中起重要作用
