概括
活动追踪器提供客观数据,以评估转移性非小细胞肺癌 (mNSCLC) 患者的健康状况. 这些可穿戴设备为预后提供了一个有希望的补充或替代传统的性能状态 (PS) 评估.
科学领域:
- 在瘤学瘤学.
- 数字健康数字健康
- 可穿戴技术可穿戴技术
背景情况:
- 绩效状态 (PS) 评估对于癌症治疗决策至关重要,但是主观的.
- 活动追踪器可以收集客观的患者生成的数据,以改善PS评估.
- 目前的PS评估方法容易导致患者,医生和家人之间的沟通失误.
研究的目的:
- 评估活动追踪器数据在转移性非小细胞肺癌 (mNSCLC) 患者的预后能力.
- 探索从活动追踪器数据中获得的新型健康指数.
- 将可穿戴传感器数据的预后性能与传统PS评估进行比较.
主要方法:
- 55名使用Fitbit®活动追踪器的mNSCLC患者的前性观察性可行性研究.
- 收集的数据包括步骤,距离,心率和活动强度.
- 定义和分析了新的指标:心率活动区不匹配 (HAM) 和过度静止心率 (eSHR).
- 使用多变量考克斯比例危险模型和哈雷尔对应指数 (C指数) 进行生存分析.
主要成果:
- 活动跟踪指标,包括每日步骤和新型指数 (HAM,eSHR),与整体存活率 (OS) 有显著关联.
- 结合PS-医生评估的预后模型显示了最高的一致性 (C指数=0.75).
- 使用每日距离 (C指数 = 0.74) 和步骤 (C指数 = 0.73) 的模型也显示出强大的预后能力.
结论:
- 可穿戴活动追踪器数据对mNSCLC患者的生存有预后.

Cancer Survival Analysis
328
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...

Kaplan-Meier Approach
100
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,...
