摘要
目的 探讨G蛋白偶联受体(GPR)120与GPR40在卵巢癌中的表达及其作为预后分子标志物的临床价值。方法 通过免疫组织化学染色检测128例卵巢癌患者的石蜡包埋样本中GPR120与GPR40表达。分析GPR120、GPR40表达与卵巢癌临床病理特征之间的关系,采用Kaplan-Meier法绘制高表达和低表达GPR120、GPR40患者的生存曲线,Cox风险回归模型分析卵巢癌患者无病生存(DFS)率的影响因素。结果 卵巢癌患者GPR120与GPR40阳性表达率分别为62.5%(80/128)和56.3%(72/128)。FIGOⅡ—Ⅲ期和组织学G3级患者的GPR120和GPR40高表达率分别高于FIGOⅠ期与组织学G1—G2级。生存分析表明,GPR120高表达者的4年DFS较低表达者下降(56.9%vs. 70.7%,Log-rankχ2=5.144,P=0.023)。此外,GPR40高表达者的DFS率亦低于低表达组(57.7%vs. 68.4%,Log-rankχ2=4.491,P=0.034)。单、多变量Cox回归分析认定GPR120高表达、GPR40高表达、FIGO分期Ⅱ—Ⅲ期和术后残留灶≥1 cm是卵巢癌患者DFS的独立影响因素。结论 GPR120与GPR40是预测卵巢癌侵袭性与不良预后的有效分子标志物,两者可能参与了卵巢癌的恶性转化与进展。
