摘要
目的:探讨晚期非小细胞肺癌(NSCLC)患者接受表皮生长因子受体酪氨酸激酶抑制剂(EGFRTKI)治疗前后血清环氧化酶-2(COX-2)变化的临床意义。方法:收集58例晚期NSCLC患者的血清,采用ELISA法检测治疗前后血清COX-2水平的变化,同时进行CT检查以判断近期疗效,并随访至疾病进展,分析血清COX-2水平的变化与近期疗效及无进展生存期(PFS)之间的关系。结果:治疗后血清COX-2水平与治疗前相比,有效患者显著降低(t=11.258,P=0.000),疾病稳定患者无显著变化(t=1.424,P=0.170),疾病进展患者则显著升高(t=-7.759,P=0.000)。有效患者治疗前血清COX-2基线水平明显高于疾病稳定和疾病进展患者(F=20.852,P=0.000)。治疗前血清COX-2水平越高,患者的PFS越长。结论:血清COX-2的检测有助于判断晚期NSCLC患者靶向治疗的疗效及可作为预测服用EGFR-TKI药物预后的指标。
Objective To explore the clinical value of expression levels of serum COX-2 in patients with advanced NSCLC before and after EGFR-TKI treatment. Methods The serum was collected from 58 cases. Before and after targeted therapy , the serum COX-2 level was examined by ELISA. Meanwhile , CT scan was exercised to evaluate the treatment. Follow-up interview was done. The relationship among the change in expression level of serum COX-2 , efficacy and PFS was analyzed. Results The serum COX-2 level significantly decreased in the response group （t = 11.258, P = 0.000） and increased in the PD group （t = -7.759, P =0.000） after EGFR-TKI treatment, and not significantly changed in the SD group （t = 1.424, P = 0.170）. Before treatment, the baseline serum COX-2 level in the response group was significantly higher than that in the SD group and the PD group （F = 20.852, P = 0.000 ）. Before the targeted therapy, the higher the level of serum COX-2 was, the longer PFS patients would enjoy. Conclusion Detection of the serum COX-2 contributes to the judgment of therapeutic effect of EGFR-TKI and can be used as a prediction of EGFR-TKI drugs outcomes for patients with advanced NSCLC.
