晚期胃癌一线化疗方案Ⅰ
方案评价
点评
DCF方案为晚期胃及胃食管结合部腺癌一线治疗的可选方案。适用于ECOG 0~1分,体能状态良好的晚期胃癌患者。该研究证据源于V325研究,该研究为一项由美国、欧洲、亚洲、拉丁美洲等34个研究中心开展的国际多中心Ⅲ期随机对照试验,旨在确立以多西他赛为基础的联合化疗在晚期胃癌及胃食管结合部位腺癌中的作用与地位。结果发现:DCF方案延长了患者无疾病进展期及生存期,提高了生活质量。但在获得高效的同时,该方案也带来了更高的毒性:DCF方案的临床实际应用受到限制。
而我国由15家胃癌治疗中心开展的mDCF方案治疗晚期胃癌中国注册临床研究是针对中国人群的V325研究的桥接试验,下调剂量的mDCF方案的治疗组在疗效近似的同时不良事件均较V325研究中的发生率下降。该研究根据中国患者特征调整了剂量,符合中国患者特点。
