晚期结直肠癌患者可受益于奥沙利铂的短周期治疗

2018-01-27 MedSci MedSci原创

研究人员在2018年胃肠癌研讨会(Gastrointestinal Cancers Symposium,ASCO-GI)上报告称,奥沙利铂的短周期治疗可能对RAS野生型的未经化疗的晚期或复发性结直肠癌患者有益。

究人员在2018年胃肠癌研讨会(Gastrointestinal Cancers SymposiumASCO-GI)上报告称,奥沙利铂的短周期治疗可能对RAS野生型的未经化疗的晚期或复发性结直肠癌患者有益。

FOLFOX方案(5-氟尿嘧啶(5-FU)、亚叶酸钙和奥沙利铂)已经作为晚期或复发性结直肠癌患者的常用一线化疗方案。 但考虑到奥沙利铂的长期给药与外周神经病变有关,因此研究人员试图在不降低疗效的前提下,缩短奥沙利铂的治疗时长以规避奥沙利铂长期使用所带来的副作用。

日本松本相泽医院的Masato Nakamura及其同事对164名年龄在20岁及以上的RAS野生型晚期/复发性结直肠癌患者实施6个周期的治疗(帕尼单抗联合FOLFOX),每2周给药一次。然后患者被随机平均分为两组(一组为帕尼单抗联合FOLFOX,另一组为帕尼单抗联合5-FU和亚叶酸钙),继续接受治疗。

结果显示,与帕尼单抗联合FOLFOX治疗组相比,帕尼单抗联合5-FU和亚叶酸钙治疗组患者发生≥2级外周神经病变的比例更低(1.8% vs 10.7 %)。两组患者的无进展生存率均明显高于设定的阈值(30%),帕尼单抗联合FOLFOX组为44.6%,帕尼单抗联合5-FU和亚叶酸钙组为47.4%。 随机分组后的中位无进展生存期分别为9.19.3个月。

因此,在不影响疗效的前提下,奥沙利铂的治疗时间可以适当缩短。
