Oncologist:真实世界评估诊断时年龄对转移性胰腺导管腺癌的治疗和预后影响

2022-03-15 网络 网络

该研究表明,老年mPDAC患者可以通过接受适当的治疗方案而大大受益。

研究表明,68%的胰腺导管腺癌(PDAC)患者年龄在65岁或以上。同时老年人在临床试验中的代表性不足,他们的治疗因多种年龄相关疾病而变得更为复杂。因此,来自美国团队开展了真实世界研究,目的是根据诊断时的年龄评估转移性PDAC (mPDAC)患者的特征、治疗率和生存结果。相关结果发表在Oncologist杂志上。

研究从Flatiron Health数据库中提取2015年1月1日-2020年3月31日期间诊断为mPDAC的患者的数据。将患者分为3个年龄组:<70岁、70-79岁和≧80岁。评估了接受一线治疗的患者比例、转移患者接受的治疗方案类型、治疗开始后的总生存期(OS)。

在8382例纳入的患者中,71.3% (n = 5973)接受了治疗。在接受治疗的患者中,诊断时<70岁占55.5% (n = 3313), 70-79岁占33.0% (n = 1972), ≧80岁占11.5% (n = 688)。

总体而言,71.3% (n = 5973)的患者接受了一线治疗,38.3% (n = 2289)的患者接受了二线治疗,33.2% (n = 761)的患者接受了三线治疗。接受治疗的患者比例随着年龄的增长而下降,年龄较大的患者接受后续治疗的可能性较小。各年龄组三线治疗比例差异无统计学意义(P =0.3158)。

在所有年龄组中,最常见的一线治疗是吉西他滨加白蛋白紫杉醇。一线吉西他滨单药治疗占≧80岁患者治疗方案的近四分之一,但对<80岁患者较少使用。≧80岁的患者中只有4.7% (n = 32)接受了FOLFIRINOX治疗,而<70岁的患者中有34% (n = 1131)接受了FOLFIRINOX治疗,70-79岁的患者中有18%接受了FOLFIRINOX治疗。

在接受至少一线治疗的患者中,中位OS随年龄增加而显著降低。

年龄<70岁的患者的中位OS为7.9个月(95% CI, 7.6-8.3个月),70-79岁的患者为6.8个月(95% CI, 6.3-7.2个月),80岁的患者为6.2个月(95% CI, 5.5-6.8个月)(p<0.0001)。然而,当比较不同治疗方案的生存结果时,中位OS在年龄组中是相似的。

综上,该研究表明,老年mPDAC患者可以通过接受适当的治疗方案而大大受益。
