Abstract

BACKGROUND/AIM: We hypothesised that the prognostic nutrition index (PNI) is useful for evaluating host immunity and response to immune checkpoint inhibitors. We investigated the effect of PNI on nivolumab monotherapy efficacy in advanced or recurrent gastric cancer (GC) or gastro-oesophageal junction cancer (GOC) patients.

PATIENTS AND METHODS

We retrospectively examined 110 patients, divided them into a high-PNI group and a low-PNI group, and compared treatment efficacy, adverse events (AEs), and survival between the groups.

RESULTS

Median overall survival (OS) was significantly longer in the high-PNI group than in the low-PNI group (205 vs. 109 days; p<0.001). Multivariate analysis revealed that low PNI was an independent risk factor for OS (hazard ratio=2.398; 95% confidence interval=1.384-4.154; p=0.002). The overall response rate and frequency of AEs were not significantly different between the groups.

CONCLUSION

PNI could be a useful prognostic factor in GC or GOC patients undergoing nivolumab monotherapy.

摘要

背景/目的:我们假设预后营养指数(PNI)可用于评估宿主免疫和对免疫检查点抑制剂的反应。我们研究了 PNI 对晚期或复发性胃癌(GC)或胃食管交界处癌(GOC)患者接受纳武利尤单抗单药治疗疗效的影响。

患者和方法

我们回顾性检查了 110 名患者,将其分为高 PNI 组和低 PNI 组,并比较了两组的治疗疗效、不良事件(AE)和生存情况。

结果

高 PNI 组的中位总生存期(OS)明显长于低 PNI 组(205 天 vs. 109 天;p<0.001)。多因素分析显示,低 PNI 是 OS 的独立危险因素(风险比=2.398;95%置信区间=1.384-4.154;p=0.002)。两组的总缓解率和 AE 发生率无显著差异。

结论

PNI 可能是 GC 或 GOC 患者接受纳武利尤单抗单药治疗的一个有用的预后因素。
