JAMA Oncol:临界可切除的胰腺导管癌的最佳新辅助治疗策略

2022-07-18 MedSci原创 MedSci原创

与mFOLFIRINOX治疗联合大分割放疗相比,在临界可切除的PDAC患者中,单独使用新辅助mFOLFIRINOX治疗更有利于良好的总生存预后

国家指南支持,临界可切除的胰腺导管腺癌 (PDAC) 可采用新辅助治疗,但最佳辅助治疗策略仍不明确。该研究比较了新辅助改良的FOLFIRINOX (mFOLFIRINOX) 联合或不联合大分割放射治疗的疗效,并与历史数据对比,以建立临界可切除的PDAC的治疗标准。

这是一项前瞻性、多中心、随机的2期临床试验,招募了126位患者,其中70位(55.6%)被分至1组(系统治疗),56位(44.4%)被分至2组(系统治疗+序贯大分割放疗)。1组患者接受8个疗程的mFOLFIRINOX治疗,2组患者接受7个疗程的mFOLFIRINOX治疗,继以大分割放疗。新辅助治疗后,没有疾病进展的患者接受胰腺切除术,随后再接受4个疗程的术后FOLFOX6治疗。主要终点是18个月时的总生存率。


两组的总生存率和无事件生存率

在126位受试患者中,62位(49%)是女性,中位年龄是64岁(范围 37-83岁)。在各组可评估的前30位患者中,1组有17位(57%)、2组有10位(33%)患者获得了R0切除,导致2组关闭,1组继续进行。1组和2组的18个月总生存率分别是66.7%和47.3%。1组和2组可评估患者的中位总生存期分别是29.8个月和17.1个月。

综上,该随机临床试验发现,与mFOLFIRINOX治疗联合大分割放疗相比,在临界可切除的PDAC患者中,单独使用新辅助mFOLFIRINOX治疗更有利于良好的总生存预后;因此,mFOLFIRINOX代表了这种情况下的参考方案。
