摘　　要：目的小细胞肺癌(small cell lung cancer,SCLC)是恶性程度极高的肺部肿瘤,其临床特点是一线化疗敏感,但易出现肿瘤复发和转移,而且在一线标准治疗失败后,二线治疗的有效率低,没有标准的二线化疗方案。本研究旨在探讨SCLC一线标准治疗失败后,二线应用伊立替康联合或者不联合顺铂方案化疗的疗效及其安全性。方法收集2015-05-01-2018-03-31北京大学肿瘤医院胸部肿瘤内二科54例一线标准治疗失败的SCLC患者临床病例资料,前瞻性观察二线伊立替康(irinotecan,CPT-11)单用或联合顺铂(IP)方案化疗的疗效与不良反应。随访患者的无进展生存期(progression free survival,PFS),采用Kaplan-Meier法曲线描述,影响因素采用Cox回归法分析。结果化疗的总体客观有效率(objective response rate,ORR)为13.0%(7/54),疾病控制率(disease control rate,DCR)为53.7%(29/54)。中位PFS 2.5个月。化疗后迟发性腹泻发生率为40.7%(22/54),中性粒细胞减少发生率为61.1%(33/54),肝功能异常发生率为18.5%(10/54),恶心呕吐发生率为42.6%(23/54)。IP和CPT-11方案化疗的ORR分别为15.2%和9.5%;DCR分别为60.6%和42.9%;中位PFS分别为2和4个月,差异均无统计学意义,均P>0.05。IP方案的腹泻和中性粒细胞减少不良反应大于CPT-11单药,但差异无统计学意义,P>0.05。Cox回归分析未发现影响PFS的独立危险因素。结论 CPT-11化疗用于SCLC一线标准治疗失败后的DCR较高,不良反应可耐受。IP方案化疗可能优于CPT-11单药化疗,PFS有延长的趋势。OBJECTIVE To investigate the efficacy and safety of irinotecan combined with or without cisplatin in the treatment of small cell lung cancer (SCLC) after failure of first-line standard therapy.METHODS Patients with SCLC were admitted into the DepartmentⅡ of Thoracic Oncology,Peking University Cancer Hospital.The patients who failed in the first-line treatment were enrolled and the related clinical records were collected.Irinotecan-based chemothera-py was given as the second-line treatment.The efficacy and adverse effects of the regimen were prospectively observed. The differences in efficacy and side effects between irinotecan combined with cisplatin(IP)regimen and CPT-11 single chemotherapy were compared.Chi square test was used to compare enumeration data and composition differences between 2 groups.Patients’progression free survival (PFS) were followed up and Kaplan-Meier method was used to analyze PFS. Single factor and Cox regression multivariate analysis were used to analyze the influencing factors of PFS.RESULTS A total of 54 patients with SCLC received second-line irinotecan-based chemotherapy between May 2015 and March 2018,of whom 49(90.7%)were males and the median age was 58 years old.The overall objective response rate (ORR) of chemo- therapy was 13.0%(7/54).The disease control rate(DCR) was 53.7%(29/54).Median PFS was 2.5 months.Side effects:the incidence of delayed diarrhea after chemotherapy was 40.7%(22/54),neutropenia was 61.1%(33/54),liver dysfunction was 18.5%(10/54),and nausea and vomiting were 42.6%(23/54).The ORR of IP and CPT-11 regimens was 15.2% vs 9.5%.DCR was 60.6%vs 42.9%,and median PFS was 2 months vs 4 months,no statistical differences were found. Side effects of diarrhea and neutropenia in IP group were higher than those in CPT-11 group,but there was no sta-tistical difference.No independent influence factors of PFS were found.CONCLUSIONS After the failure of first-line standard treatment for SCLC,disease control rate of irinotecan-based chemotherapy is high,with adverse effects
