  • 摘要:   目的  分析安罗替尼三线治疗难治型晚期结直肠癌的疗效及安全性。  方法  收集并分析2014年9月至2016年8月中国医学科学院肿瘤医院收治的53例晚期结直肠癌患者临床信息,观察、评估安罗替尼的疗效及安全性。  结果  患者随机分为安罗替尼组和安慰剂组。安罗替尼组与安慰剂组的中位总生存期(overall survival,OS)分别为9.37个月和8.23个月;中位无进展生存期(progression-free survival,PFS)分别为5.03个月和1.33个月(HR=0.27,95%CI:0.13~0.54)。两组患者客观缓解率(objective response rate,ORR)分别为2.94%和0;安罗替尼组的疾病控制率(disease control rate,DCR)显著高于安慰剂组(88.24% vs. 36.84%,P<0.001)。26例RAS/BRAF野生型患者中,安罗替尼组中位PFS显著长于安慰剂组(5.37个月 vs. 1.33个月),DCR显著优于安慰剂组(93.33% vs. 36.36%,P=0.003)。最常见的≥3级安罗替尼相关不良事件为高血压(17.65%)、腹泻(8.82%)和掌跖红肿综合征(8.82%)。  结论  安罗替尼后线治疗晚期结直肠癌可改善患者无进展生存期(progression-free survival,PFS),提升DCR,且安全性良好,为晚期结直肠癌的治疗提供了新思路。然而对于RAS/BRAF野生型人群的临床获益趋势有待进一步验证。
