摘要目的 探讨一线含铂方案及表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)治疗失败后的晚期非小细胞肺癌(NSCLC)患者接受挽救性化疗的疗效和安全性.方法 对55例一线含铂方案及后续EGFR-TKI治疗失败的晚期NSCLC患者行挽救性化疗,其中培美曲塞单药化疗24例,多西他塞单药化疗21例,其他方案化疗10例.至疾病进展或患者拒绝继续治疗.评价挽救性化疗的客观缓解率(ORR)、疾病控制率(DCR)及患者的无进展生存时间(PFS).结果 55例患者均可评价疗效,其中部分缓解(PR)7例(12.7%),稳定(SD)21例(38.2%),进展(PD)27例(49.1%),无完全缓解(CR)患者.ORR为12.7%,DCR为50.9%.全组患者的中位随访时间为5.5个月,中位PFS为2.0个月.不同性别、PS评分及化疗方案患者的近期疗效及PFS差异均无统计学意义(均P＞0.05).EGFR-TKI治疗时间≥6个月患者的ORR(21.1%)和DCR(73.7%)均明显高于EGFR-TKI治疗时间＜6个月的患者(ORR为8.3%,DCR为38.9%;均P＜0.05);EGFR-TKI治疗时间≥6个月患者与＜6个月患者的中位PFS分别为4.5月和2.0个月,差异亦有统计学意义(P=0.008).55例患者均可评价不良反应,主要表现为骨髓抑制,患者均能耐受.全组未发生治疗相关性死亡.结论 一线含铂方案及EGFR-TKI治疗失败后的晚期NSCLC患者能从挽救性化疗中获益,尤其是对EGFR-TKI治疗时间≥6个月的患者.晚期NSCLC患者对于挽救性化疗的耐受性良好.

abstractsObjective Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)such as gefitinib and erlotinib are used as standard 2nd/3rd line therapy in previously treated advanced nonsmall cell lung cancer ( NSCLC ). However, the optimal treatment for patients who experienced disease progression after chemotherapy and EGFR-TKI is unclear. The aim of this study was to explore the efficacy and safety of a salvage chemotherapy in advanced NSCLC patients who failed the previous treatment of platinum-based chemotherapy and EGFR-TKI. Methods Clinicopathological data of 55 cases of advanced NSCLC patients who failure of first-line platinum-based chemotherapy and subsequent treatment with TKI were collected and analyzed. The patients were of PS = 0-2, and with normal vital organ function. Patients
