概括
在高级肝细胞癌 (aHCC) 试验中,无进展生存期 (PFS) 是可疑的. 许多患者表现出不同的病变行为,一些瘤生长,而另一些则缩小,即使使用相同的治疗.
科学领域:
- 肝胆瘤学 肝胆瘤学
- 临床试验方法论 临床试验方法论
- 放射学和成像分析分析.
背景情况:
- 无进展生存率 (PFS) 是高级肝细胞癌 (aHCC) 临床试验中常见的代用终点.
- 由于与整体存活率的潜在差异,存在对PFS可靠性的担忧.
- 了解个体的病变行为对于准确的反应评估至关重要.
研究的目的:
- 分析在接受aHCC全身治疗的患者中个别肝病变的时间行为.
- 量化病变对治疗反应的分歧程度 (DOD).
- 作为临床试验终点,评估不同病变行为对PFS的影响.
主要方法:
- 分析了来自aHCC六项临床试验的连续病变大小测量.
- 在每次患者访问中,与基线相比,损伤大小的百分比变化被计算出来.
- 根据病变行为相似性,患者被分类为DOD组 (0-2).
- 根据治疗组总结了结果,详细说明了随着时间的推移,每个DOD类别中患者的比例.
主要成果:
- 在8260次访问中,很大一部分患者表现出不同的病变行为.
- 大约58%的患者表现出类似的损伤行为 (DOD 0),38%显示出一些差异 (DOD 1),4%显示出完全差异 (DOD 2).
- 在同一个患者的肝脏中,个别病变表现出尽管持续治疗,但其大小增加和减少.
结论:
- 在aHCC临床试验中使用PFS等基于进展的指标作为主要终点时,建议谨慎使用.
- 相当比例的患者在治疗后持续表现出患者内病变异质.
- 单个病变的不同行为挑战了PFS在评估aHCC治疗疗效的直接应用.

Combination Therapies and Personalized Medicine
5.1K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Factors Affecting Drug Response: Overview
2.4K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...
