紫杉醇、吉西他滨以及顺铂的三联疗法极大程度上提高了转移性胰腺癌患者生存期

转移性胰腺癌患者的基因组常常含有染色体畸变,与DNA损伤剂(如铂)的治疗敏感性有关。近日研究人员探讨紫杉醇、吉西他滨联合顺铂治疗转移性胰管腺癌(PDA)的疗效。

25名未经治疗的转移性PDA患者参与研究,第1和8天接受紫杉醇、吉西他滨以及3个剂量的顺铂(25 mg/m2, 37.5 mg/m2, and 50 mg/m2)治疗,每21天为1个循环。研究的主要终点为完全缓解率。

患者平均年龄65.0岁,男性占56%,顺铂的最大耐受剂量为25 mg/m2。最常见的治疗相关3级及以上不良事件包括血小板减少17例(68%),贫血8例(32%),中性粒细胞减少6例(24%)。3名患者死亡,其中2名与治疗相关。患者平均完成了8轮治疗。24名患者参与疗效评估,其中2名实现完全缓解(8%)、15名实现部分缓解(62%)、4名患者病情稳定(17%)、3名病情进展(12%)。平均总生存期为16.4个月。1年后16名患者存活(64%)、2年后10名患者存活(40%)、3年后4名患者存活(16%)、4年以上1名患者存活(4%)。患者的总生存期36-59个月。平均无进展生存期10.1个月。治疗的总响应率为71%,疾病控制率为88%。

研究发现,紫杉醇、吉西他滨以及顺铂的三联疗法极大程度上提高了转移性胰腺癌患者生存期。
