概括
在瘤学中,向试验仿真 (TTE) 显示了大量的框架采用,但与随机对照试验 (RCT) 的一致性较差. 这凸显了TTE在评估治疗疗效方面的潜在局限性,强调了需要标准化报告的必要性.
科学领域:
- 流行病学 流行病学
- 临床试验 临床试验
- 瘤学研究研究
背景情况:
- 目标试验模拟 (TTE) 框架在瘤学中越来越多地用于模拟使用观察数据的随机对照试验 (RCT).
- 本综述评估了TTE在瘤学研究中的应用,坚持和结果一致性.
研究的目的:
- 描述瘤学TTE的特征.
- 评估已发表的瘤学研究中对TTE框架的遵守.
- 评估TTE结果与相应的RCT发现之间的一致性.
主要方法:
- 在MEDLINE和Embase进行了系统的文献搜索.
- 包括评估治疗干预措施的瘤学TTEs.
- 数据提取的重点是研究特征,框架坚持,队列细节和结果一致性,使用科恩的卡帕和皮尔森的相关系数.
主要成果:
- 分析了来自94项研究的106个独特的TTE.
- 对治疗策略和结果的报告率很高,但对零时间 (75.5%) 和混调整 (20.8%的绩效状态) 较低.
- 在TTE和相应的RCT之间发现了生存结果的差到相当一致性 (科恩卡帕=0.20) 和中度相关性 (皮尔森r=0.44).
结论:
- 瘤学TTEs显示了大量的框架采用,但与RCT的协议有限.
- 由于对混因素 (例如,绩效状态) 的调整不足和报告差距造成的潜在偏差,挑战了TTE作为RCT替代品.
- 标准化报告准则,如TARGET框架,对于提高TTE在瘤学研究中的实用性至关重要.

Targeted Cancer Therapies
9.0K
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.

Clinical Trials: Overview
5.2K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
