概括
20毫克卡博桑提尼布的初始剂量是日本患者不可切除的肝细胞癌 (uHCC) 的安全选择. 血清阿尔多酶水平可以指导适当的卡博桑提尼布剂量调整,以获得更好的治疗结果.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 肝细胞癌 (HCC) 是一个重要的全球健康问题.
- 卡博赞提尼布是一种用于不可切除的HCC的向治疗.
- 优化卡博赞提尼布的剂量对于最大限度地提高疗效和最大限度地降低毒性至关重要.
研究的目的:
- 为了评估卡博赞提尼布治疗在日本患者不可切除的HCC.评估结果.
- 调查不同卡博赞提尼布剂量设置和修改对治疗结果的影响.
- 探索卡博赞提尼布最低度,血清阿尔多酶水平和临床结果之间的关系.
主要方法:
- 对34名日本患者进行了回顾性分析,这些患者患有无法切除的HCC,并接受了卡博赞提尼布治疗.
- 在18名患者中,每周测量卡博赞提尼布的最低度 (Ctrough) 6周.
- 高剂量 (≥40毫克) 和低剂量 (20毫克) 组之间的结果比较,包括剂量修改,相对剂量强度 (RDI),无进展生存 (PFS) 和整体生存.
主要成果:
- 在高剂量和低剂量组之间没有观察到RDI,PFS或总生存时间的显著差异.
- 与高剂量组相比,低剂量组的剂量减少或中断持续时间较长.
- 更高的RDI (≥33.4%) 显示出更长的PFS中位数趋势.
- 血清阿尔多酶水平与Ctrough有显著的相关性.
- 2周内血清阿尔多酶 (≥8.7 U/L) 升高与早期剂量减少或中断有关.
结论:
- 20毫克卡博桑提尼布的初始剂量似乎是日本患者不可切除的HCC.安全和可行的选择.
- 血清阿尔多酶水平可以作为指导适当的卡博桑提尼布剂量修改的有价值的生物标志物.
- 进一步的研究可以探索阿尔多酶监测对HCC个性化卡博桑提尼布治疗的实用性.

Combination Therapies and Personalized Medicine
4.9K
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...

Targeted Cancer Therapies

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.
