背景:评估和比较立体定向放疗(stereotactic body radiation therapy, SBRT)联合诱导化疗和 SBRT 联合辅助化疗治疗早期但无法手术的胰腺癌的疗效。
方法:2012 年至 2016 年,确诊为早期胰腺癌患者纳入研究。Cox 风险模型筛选与预后相关的因素。倾向性得分匹配比较两种不同治疗方法的疗效。
结果:分别有 48 名和 52 名患者接受 SBRT 联合诱导化疗和 SBRT 联合辅助化疗。中位生存期(overall survival, OS)为 17.5 个月(95% CI: 15.8-19.2 个月),中位疾病无进展期(progression free survival, PFS)为 13.7 个月(95% CI: 12.3-15.1 个月)。接受 SBRT 联合辅助化疗(P <0.001)、CA19-9 较治疗前显著下降(<0.001)和生物等效剂量 ≥60Gybiological effective dose, α/β=10, BED10)(=0.024)的患者具有较好的 OS,同时前两者与 PFS 明显相关。倾向性得分匹配后,每组有 23 名患者纳入分析。与接受 SBRT 联合诱导化疗的患者相比,接受 SBRT 联合辅助化疗的患者具有较好的 OS 和 PFSOS23.1 个月 vs. 15.6 个月,<0.001PFS18.0 个月 vs. 11.6 个月,<0.001)。
结论:SBRT 对于早期胰腺癌是安全有效的。SBRT 联合辅助化疗,可能可以作为早期但不适合手术治疗的胰腺癌患者的优选的方法。
