摘　　要：目的观察分子靶标指导下个体化治疗与长春瑞滨治疗表皮生长因子受体（EGFR）野生型的老年晚期非小细胞肺癌（NSCLC）的疗效及不良反应。方法2010年6月至2012年10月福建省肿瘤医院经病理确诊且为EGFR野生型的86例老年晚期NSCLC患者，其中男69例，女17例，年龄70～83岁。通过SPSS16．0软件随机程序按照1：1的比例随机分为两组，分子靶标指导下个体化治疗43例（研究组），根据肿瘤组织核苷酸切除修复交叉互补基因1（ERCC1）、核苷酸还原酶调节因子1（RRM1）、III型β-微管蛋白及胸苷酸合成酶（TS）的表达情况给予顺铂、吉西他滨、紫杉醇、培美曲塞单药方案化疗。对照组43例，给予长春瑞滨25mg／m2第1天、第8天，每21天为1个周期单药方案化疗。结果研究组和对照组的无进展生存期分别为4．0个月（95％CI为3．1～4．9）和3．0个月（95％CI为2．4～3．6），两组比较差异有统计学意义（χ2=4．750，P=0．029）。客观有效率分别为23％（10／43）和19％（8／43），差异无统计学意义（χ2=0．281，P=0．596），疾病控制率分别为79％（34／43）和77％（33／43），差异无统计学意义（χ2=0．068，P=0．795），两组的中位生存期分别为8．3和7．5个月，差异无统计学意义（χ2=0．756，P=0．385）。研究组和对照组不良反应相似，主要为血液学毒性、恶心、呕吐、脱发、关节肌肉酸痛及乏力等，多为Ⅰ、Ⅱ级不良反应，两组均无药物治疗相关死亡病例。结论分子靶标指导下个体化治疗EGFR野生型的老年晚期NSCLC患者与对照组相比，无进展生存期延长，客观有效率、疾病控制率和生存期未明显提高，值得临床进一步研究。Objective To compare the efficacy and toxicity of chemotherapy under the guidance of molecular markers and with vinorelbine in elderly patients with epidermal growth factor receptor （EGFR） wild-type advanced non-small cell lung cancer （ NSCLC ）. Methods A total of 86 elderly patients with pathologically-confirmed advanced NSCLC with EGFR wild-type were recruited between June 2010 to October 2012. There were 69 males and 17 females, aging from 70 to 83 years. They were divided randomly into 2 groups according to the proportion of 1 ： 1 by SPSS 16. 0 software. The study group received chemotherapy （cisplatin, gemcitabine, paclitaxel, and pemetrexed ） under the guidance of molecular markers （excision repair cross-complementing 1 ERCCI, ribonucleotide reductase M1 RRM1, Class III beta-tubulin, thymidylatesynthetase TS）. The control group received vinorelbine 25 mg/m2 days 1 and 8 with 21 days as a cycle. Results The progression-free survival （PFS） of the study group and the control group was 4. 0 months （95% CI： 3. 1 - 4. 9） and 3.0 months （95% CI： 2.4 - 3.6 ） respectively, the difference being statistically significant （ χ2 = 4. 750, P = 0. 029）. The objective response rate （ORR） was 23% （ 10/43 ） and 19% （8/43） （X2 =0. 281 ,P =0. 596）, the disease control rate （DCR） was 79% （34/43） and 77% （33/43） （ χ2 = 0. 068,P = 0. 795 ） , and the median overall survival （OS） was 8.3 months and 7.5 months （χ2 =0. 756,P = 0. 385）, respectively; the differences being not significant. Adverse effects were similar between the study group and the control group. The most commonly seen adverse events were hematological toxicity, nausea, vomiting, fatigue, alopecia, joint and muscle pain. Most of the toxicity was of grade I and grade II. There was no treatment-related death. Conclusions The PFS was prolonged in elderly patients with EGFR wild-type advanced NSCLC under the guidance of molecular markers, but there was no improvement in ORR, DCR and OS. Furthe
