概括
提斯莱利祖马布与凝胺和TS-1化疗结合使用显示,晚期胆囊癌 (GBC) 患者的生存结果有所改善. 与tiselelizumab与lenvatinib相比,这种组合疗法提供了一种安全有效的治疗选择.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 胃肠道瘤学 胃肠道瘤学
背景情况:
- 胆囊癌 (GBC) 是一种具有挑战性的恶性瘤,在手术后复发率很高.
- 化疗是高级GBC的主要非手术治疗方法.
- 编程细胞死亡蛋白1 (PD-1) 抑制剂和向疗法为高级GBC管理提供了新的途径.
研究的目的:
- 为了评估tislelizumab与gemcitabine和TS-1 (GS) 化疗相结合的疗效和安全性,而不是tislelizumab与lenvatinib在高级GBC患者中.
- 为了比较两个治疗臂之间的总生存率 (OS),无进展生存率 (PFS),客观反应率 (ORR) 和疾病控制率 (DCR).
主要方法:
- 在2019年6月至2022年6月期间治疗的61名晚期GBC患者的回顾性分析.
- 患者接受了tislelizumab加GS化疗 (n=32) 或tislelizumab加lenvatinib (n=29).
- 使用RECIST 1.1标准评估有效性,评估了OS,PFS,ORR,DCR和CA199瘤标志物.
主要成果:
- 与tislelizumab加lenvatinib组相比,tislelizumab加GS化疗组的中位寿命 (19.64个月) 和PFS (15.44个月) 显著更长,与tislelizumab加lenvatinib组相比.
- 在GS化疗组中,客观反应率 (ORR) 为59.38%,疾病控制率 (DCR) 为81.3%.
- 在两组治疗中,与治疗相关的不良事件是可比的,这表明安全性概况相似.
结论:
- 与GS化疗相结合的tislelizumab是高级GBC的安全和更有效的治疗策略.
- 这种组合治疗是改善晚期胆囊癌患者治疗结果的有希望的选择.

Combination Therapies and Personalized Medicine
4.8K
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.
