背景情况:
- 准确预测整体存活率 (OS) 对黑色素瘤患者治疗计划至关重要.
- 从基线计算机断层扫描 (CT) 扫描的身体组成分析提供了一个潜在的预后工具.
- 深度学习 (DL) 方法可以自动化和增强身体成分分析.
研究的目的:
- 调查基于DL的身体组成特征对黑色素瘤患者的OS的预后价值.
- 从CT扫描中识别体积组成特征,从而预测患者的生存率.
- 评估将基于DL的身体成分分析纳入常规瘤分期的可行性.
主要方法:
- 一个DL网络对495名黑色素瘤患者的腹部和胸部CT扫描进行了细分.
- 计算了 Sarcopenia 指数 (SI),骨髓炎脂肪指数 (MFI) 和内脏脂肪指数 (VFI).
- 评估了SI,MFI和VFI对OS的预后意义,并对428名患者进行了外部验证.
主要成果:

Cancer Survival Analysis
311
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
62
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,...
