-
摘要:
目的 比较阿美替尼和奥希替尼治疗表皮生长因子受体(epidermal growth factor receptor,EGFR)突变晚期非小细胞肺癌(non-small cell lung carcinoma,NSCLC)的临床疗效及安全性。 方法 回顾性收集2019年1月至2022年12月于云南省第一人民医院接受治疗的EGFR突变晚期NSCLC患者共计139例,经纳排标准筛选后共有104例患者纳入本次研究,按治疗药物分为奥希替尼组和阿美替尼组,每组52例。奥希替尼组使用甲磺酸奥希替尼片80 mg,每天1次,阿美替尼组使用甲磺酸阿美替尼片110 mg,每天1次。观察2组患者的疾病控制率(disease control rate,DCR)、客观缓解率(objective remission rate,ORR)、无进展生存期(progression-free survival,PFS)和总生存期(overall survival,OS),评估患者不良反应发生情况,利用COX回归模型分析影响患者生存期的关键因素。 结果 2组患者的DCR无统计学意义,阿美替尼组的ORR显著高于奥希替尼组,阿美替尼组患者的中位无进展生存期(median progression-free survival,mPFS)显著优于奥希替尼组(P = 0.045)。COX回归模型显示,临床分期为Ⅲ期(HR = 2.25,95%Cl 1.28~3.95,P = 0.005)、无脑转移(HR = 0.59,95%Cl 0.35~0.98,P = 0.040)、三代TKI类型为阿美替尼(HR = 1.82,95%Cl 1.15~2.87,P = 0.011)的患者死亡风险明显降低。 结论 阿美替尼与奥希替尼治疗EGFR突变晚期NSCLC患者的近期疗效相当,长期疗效方面,阿美替尼的mPFS和总OS都显著优于奥希替尼,且安全性更佳。 Abstract:Objective To compare the efficacy and safety of osimertinib and aumolertinib in the treatment of advanced non-small cell lung carcinoma (NSCLC) with epidermal growth factor receptor (EGFR) mutation. Methods A total of 139 patients with EGFR-mutated advanced NSCLC treated in the First People's Hospital of Yunnan Province from January, 2019 to December, 2022 were retrospectively collected. After screening by that row of criteria, 104 patients were included in this study. According to the treatment drugs, they were divided into osimertinib group and aumolertinib group, with 52 cases in each group. The osimertinib group received osimertinib mesylate tablets 80 mg once daily, and the aumolertinib group received aumolertinib mesylate tablets 110 mg once daily. The disease control rate (DCR), objective remission rate (ORR) and progression-free survival (PFS) of the two groups were observed. PFS and overall survival (OS) were evaluated. The Cox regression model was used to analyze the key factors affecting patient survival. Results The ORR of aumolertinib group was significantly higher than that of osimertinib group. The median progression-free survival (mPFS) of aumolertinib group was significantly longer than that of osimertinib group (P = 0.045). Cox regression model showed that clinical stage Ⅲ(HR = 2.25, 95%Cl 1.28~3.95, P = 0.005), no brain metastasis (HR = 0.59, 95%Cl 0.35~0.98, P = 0.040), third generation TKI type aumolertinib (HR = 1.82, 95%CI 1.15~2.87, P = 0.011). Conclusion Aumolertinib and osimertinib have similar clinical efficacy in the treatment of advanced NSCLC patients with EGFR mutation. However, in terms of long-term efficacy, aumolertinib has significantly better median PFS and overall OS, and higher safety than osimertinib. -
