EGFR及MMP-9在上皮性卵巢癌组织中的表达及其与预后的关系

目的:研究表皮生长因子受体(EGFR)及基质金属蛋白酶-9(MMP-9)在上皮性卵巢癌中的表达,分析其与卵巢癌临床病理特征及预后的关系。方法:采用RT-PCR方法检测EGFR及MMP-9 mRNA在上皮性卵巢癌、卵巢良性肿瘤和正常卵巢组织的表达。结果:卵巢癌组织中EGFR和MMP-9 mRNA的阳性表达率分别为64.44%(29/45)、73.33%(33/45),相对表达水平为0.81±0.23、0.89±0.25,均明显高于卵巢良性肿瘤和正常卵巢组织,差异均有显著统计学意义(P均<0.05)。两者在有淋巴结转移的癌组织中的相对表达量均明显高于无淋巴结转移组,Ⅲ～Ⅳ期癌组织中的表达高于Ⅰ～Ⅱ期,差异均有统计学意义(P<0.01)。卵巢癌组织EGFR和MMP-9的表达呈显著正相关。Long-rank分析显示,EGFR和MMP-9共同表达患者的累积生存率明显低于阴性者,差异有显著统计学意义(P<0.05)。结论:上皮性卵巢癌组织中EGFR和MMP-9均呈现高表达,并且与卵巢癌的临床分期、淋巴结转移及患者的生存期密切相关,可作为判断上皮性卵巢癌恶性生物学行为和预后的重要参考指标。

Expression of EGFR and MMP-9 in epithelial ovarian cancer and their correlation with prognosis of patients

Objective:To investigate the expression of epidermal growth factor receptor(EGFR)and matrix metalloproteinase-9(MMP-9)in epithelial ovarian cancer and their correlation with clinical pathological features and prognosis of the patients.Methods:Expression of EGFR and MMP-9 mRNA in ovarian cancers,benign ovarian tumor and normal ovarian tissues were detected by RT-PCR assay.Then the correlation between EGFR and MMP-9 and their relationship with clinical pathological features of ovarian cancer were explored.Res...
