概括
肺免疫预后指数 (LIPI) 和ECOG性能状态 (PS) 可以预测使用免疫检查点抑制剂 (ICI) 治疗的晚期癌症患者的早期死亡率. 这些因素有助于确定不太可能从ICI治疗中受益的患者.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 癌症研究 癌症研究
背景情况:
- 免疫检查点抑制剂 (ICI) 是高级固体癌症的标准治疗方法.
- 对ICI的耐药性导致早期死亡率 (EM),这是一个重大挑战.
- 对EM的预后因素,包括肺免疫预后指数 (LIPI),尚未得到充分研究.
研究的目的:
- 用ICI治疗的晚期固体瘤患者早期死亡 (EM) 的预后因素的识别.
- 开发和验证90天死亡率的预测模型.
- 评估LIPI和ECOGPS对EM和早期进展的预后价值.
主要方法:
- 对637名先进实体瘤患者进行了回顾性观察性研究,这些患者接受了ICI治疗.
- 后勤回归模型用于识别与EM和90天进展相关的因素.
- 开发和外部验证用于预测90天死亡率的诺姆图.
主要成果:
- 21.3%的患者在90天内死亡; 8.4%在30天内死亡; 34.5%的患者出现早期进展.
- ECOG PS 2和高/中等LIPI得分独立与90天死亡率相关.
- 一种结合LIPI和ECOGPS的诺米克图实现了90天死亡预测的AUC值为0.76,并得到了外部验证 (AUC值为0.72).
结论:
- LIPI和ECOG PS是接受ICI治疗的晚期癌症患者90天死亡率的独立预测指标.
- 此外,LIPI还证明了30天死亡率和早期进展的预后有效性.
- 这些发现有助于识别那些可能无法从ICI治疗中受益的患者.

Cancer Survival Analysis
329
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...

Tumor Immunotherapy
489
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Kaplan-Meier Approach
104
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...
