目的探讨一代表皮生长因子受体(EGFR)酪氨酸激酶抑制剂(TKI)一线治疗晚期非小细胞肺癌(NSCLC)EGFR基因敏感突变患者的无进展生存(PFS)时间获益分析。方法随访2016—2017年中南大学湘雅医院一代EGFR-TKI一线治疗的166例非小细胞肺癌患者,根据PFS将患者分为PFS≤3个月组、>3~<12个月组、≥12个月组,分析PFS的获益因素。结果一代EGFR-TKI为影响PFS的独立因素(P<0.05),其中厄洛替尼进展的风险是埃克替尼的2.16倍,吉非替尼进展的风险是埃克替尼的4.48倍。PFS≤3个月和PFS≥12个月两组的Logistic回归分析显示,埃克替尼组疗效最佳(埃克替尼对吉非替尼,P=0.009;埃克替尼对厄洛替尼,P=0.006),EGFR 19号外显子del (19del)突变组优于EGFR 21号外显子L858R点突变组(21L858R)(P=0.024),腺癌组优于非腺癌组(P=0.044),中分化组优于低分化组(P=0.022)。多因素分析显示,埃克替尼组疗效优于厄洛替尼和吉非替尼组(P分别为0.018和0.006),腺癌组优于非腺癌(P=0.015),中分化组优于低分化组(P=0.034)。结论组织学类型、分化程度、EGFR基因等基线状态的不同可致不同PFS,一代EGFR-TKI药物为影响PFS的独立因素。
Objective Explore the clinical benefit factors of progression-free survival(PFS) in sensitive epithelial growth factor receptor(EGFR) gene mutated advanced non-small cell lung cancer patients treated with first-generation of EGFR tyrosine kinase inhibitor(TKI).Methods The clinical data of 166 patients who received first-line treatment with first-generation EGFR-TKI were retrospectively collected in 2016-2017 from Xiangya Hospital, Central South University. The patients were divided into three groups: PFS≤3 m,3 m
