概括
局部晚期胃癌 (LAGC) 的患者对新辅助疗法 (NAT) 的反应不佳,面临高复发率. 完成辅助化疗可以改善这些反应不良患者的生存率.
科学领域:
- 在瘤学瘤学.
- 胃肠病学 胃肠病学
- 手术瘤学手术瘤学
背景情况:
- 新辅助疗法 (NAT) 是局部晚期胃癌 (LAGC) 的标准.
- 很大一部分患者对NAT反应不佳,导致不良结果.
- 这种响应较差的子组的预后需要进一步调查.
研究的目的:
- 分析LAGC患者的生存和复发模式,这些患者对NAT的反应不佳.
- 确定复发的预测因素,并为该子组制定后续策略.
主要方法:
- 对接受NAT的LAGC患者进行多中心回顾性研究.
- 瘤回归分级 (贝克尔系统) 定义了不良反应 (TRG 2-3).
- 评估整体生存 (OS),无复发生存 (RFS) 和复发模式.
主要成果:
- 包括648名患者; 3年的OS和RFS分别为54.6%和55.2%.
- 复发发生在299名患者中,远程和腹转移是常见的.
- ypN+状态是复发的最强独立预测因素 (OR = 2.73).
- 肝转移在TRG 3与TRG 2 (14.1%与5.3%) 中较高.
- 完成>4个辅助化疗周期改善了生存结果,尽管NAT反应不佳.
结论:
- 在LAGC中,NAT反应较差的患者表现出高的复发率,特别是在手术后的第一年.
- ypN+状态是这个患者群体中复发的关键预测因素.
- 辅助化疗的完成为NAT反应较差的患者提供了生存益处.

Cancer Survival Analysis
291
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Comparing the Survival Analysis of Two or More Groups

Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...
