摘要 目的探讨FOLFIRI联合EGFR单抗治疗不同部位Kras基因野生型结直肠癌肝转移(CRLM)患者的疗效。方法 38例CRLM根据原发肿瘤部位不同分为右半结肠癌组(A组)与左半结肠癌组(B组),最终A组10例,B组28例患者完成入组。两组均采用EGFR单抗联合FOLFIR化疗方案进行化疗,评估两组总体有效率(ORR)、转化情况、总生存期(OS)、无进展生存期(PFS)与毒副反应。结果经治疗,A组ORR为30.0%(3/10),B组为60.7%(17/28),差异有统计学意义(P<0.05)。共8例部分缓解患者的肝转移瘤转化成功,达到了可切除标准,行手术或局部射频消融治疗,其中R0切除(消融)6例,R1切除(消融)2例。两组均完成治疗及随访,A组OS为19.9个月,B组为37.7个月,差异有统计学意义(P=0.03)。A组PFS为9.6个月,B组为16.0个月,差异无统计学意义(P>0.05)。两组毒副反应大部分为0~Ⅱ级,对症治疗后均可耐受,未影响后续治疗。结论 FOLFIRI联合EGFR单抗对于不同部位Kras野生型CRLM患者均安全有效,可以达到的治疗获益。左半结肠CRLM患者ORR及OS优于右半,可以作为一线治疗方案。右半结肠Kras野生型CRLM患者以肿瘤缩小为目标的转化治疗也可以选择。
