背景情况:
- 胰腺癌 (T1-3NxM0) 的生存结果受治疗方式 (手术与化疗) 的影响.
- 选择偏差和不朽时间偏差使得观察性研究中因果效应的估计变得复杂.
- 需要严格的方法来准确地比较手术与化疗的生存益处.
研究的目的:
- 估计手术与化疗对胰腺癌患者生存的因果效应.
- 用一种随机试验的新型模拟来解决选择偏差和不朽时间偏差.
- 为了比较手术和化疗干预之间的生存结果.
主要方法:

Targeted Cancer Therapies
7.6K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Cancer Survival Analysis
348
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...
