目的：回顾性分析XELOX方案联合贝伐单抗治疗中国患者转移性结肠癌的疗效与安全性。方法入选2010年4月～2013年9月来浙江省仙居县人民医院治疗的40名转移性结直肠癌患者，其中男性22名，女性18名。给予XELOX方案治疗：包括首日静脉滴注130 mg/m2奥沙利铂2h+口服1000 mg/m2卡培他滨，日2次，持续2 w，3 w为一个治疗周期。首剂卡培他滨于治疗开始首日晚服用，末剂于治疗开始后15日晨服用。贝伐单抗剂量为7.5 mg/kg，静脉滴注30～90 min。结果中位无进展生存期（progression-free survival，PFS）为290 d（95%CI：222～409 d）；中位总生存率（overall survival，OS）为816 d（95%CI：490～842 d）,缓解率为67.5%，疾病控制率为90%。结论 XELOX联合贝伐单抗治疗方案治疗中国转移性结肠癌患者，可以提高患者存活率，与此前针对西方患者进行的研究结果相同。%Objective To observe the efifcacy and safety of XELOX plus bevacizumab as a ifrst-ine treatment for Chinese patients with metastatic colorectal cancer. Methods In this study, we retrospectively reviewed cases in which XELOX plus bevacizumab were administered in order to evaluate its efifcacy and safety in clinical practice.In total, 40 patients with mCRC who presented at Fuchu Hospital received XELOX plus bevacizumab as a ifrst®line treatment from September, 2009 to April, 2012. Eligible patients had histologically conifrmed mCRC. XELOX consisted of a 2-h intravenous infusion of oxaliplatin 130 mg/m 2 on day 1 plus oral capecitabine 1,000 mg/m 2 twice daily for two weeks of athree®week cycle. Overall survival (OS) and survival benefit were analyzed when patients continued with XELOX plus bevacizumab beyond disease progression. Results The median progression®free survival (PFS) was 290 days [95%conif-dence interval (CI):222®409 days] and the median OS was 816 days (95%CI:490®842 days). The response rate (RR:complete plus partial response) was 67.5%, and the disease control rate (RR plus stable disease) was 90%. Conclusion XELOX plus bevacizumab may be considered a routine ifrst®line treatment option for patients with mCRC.
