Keap1在非小细胞肺癌中的表达及与化疗疗效相关性的研究
背景与目的已有研究表明Kelch样环氧氯丙烷相关蛋白1(Kelch-like ECH-associated protein1,Keap1)与铂类耐药相关。本研究旨在探讨Keap1在进展期非小细胞肺癌(non-small cell lung cancer,NSCLC)中的表达及其与一线含铂化疗方案疗效的相关性。方法应用免疫组化检测50例进展期NSCLC患者组织标本中Keap1的表达。结果进展期NSCLC患者中Keap1高表达率为26.0%;Keap1表达水平与化疗疗效、无进展生存期(progression free survival,PFS)有关(P〈0.05),而与性别、年龄、吸烟、病理类型、...

Summary: | 背景与目的已有研究表明Kelch样环氧氯丙烷相关蛋白1(Kelch-like ECH-associated protein1,Keap1)与铂类耐药相关。本研究旨在探讨Keap1在进展期非小细胞肺癌(non-small cell lung cancer,NSCLC)中的表达及其与一线含铂化疗方案疗效的相关性。方法应用免疫组化检测50例进展期NSCLC患者组织标本中Keap1的表达。结果进展期NSCLC患者中Keap1高表达率为26.0%;Keap1表达水平与化疗疗效、无进展生存期(progression free survival,PFS)有关(P〈0.05),而与性别、年龄、吸烟、病理类型、分化程度、转移和总生存期无关(P〉0.05)。Keap1高表达组的中位PFS明显高于低表达组(P=0.002)。多因素分析表明Keap1表达水平是一线化疗方案PFS的独立预测因素(P=0.007)。结论 Keap1与进展期NSCLC一线化疗疗效和PFS有关,Keap1可能成为新的化疗疗效预测指标。 |

The aim of this study is to investigate the protein expres- sion levels of Keapl in non-small cell lung cancer (NSCLC) patients as well as to correlate its expression with the response rate (RR), progression-free survival (PFS), and overall survival (OS) of patients treated with platinum-based first-line chemother- apy. Methods The immunohistochemical analysis of Keapl expression was performed using tumor samples from 50 patients with stage III or IV NSCLC. Results The high expression ratio of Keapl was 26.0%. The Keap1 expression was significantly correlated with the RR and PFS after platinum-based chemotherapy (P〈0.05) but not with the gender, age, sm |
