概括
在亚洲患者中,PD-1/PD-L1抑制剂加上化疗显著改善了亚洲患者的IIIb-IV期非小细胞肺癌的存活率. 虽然这种组合疗法有效,但会增加与免疫相关的不良事件,需要仔细监测.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 临床试验 临床试验
背景情况:
- PD-1/PD-L1抑制剂加上化疗 (PC) 是已确立的高级非小细胞肺癌 (NSCLC) 的治疗方法.
- 关于PC有效性和安全性的数据有限,特别是在亚洲人群中.
- 需要随机对照试验 (RCT) 的最新证据.
研究的目的:
- 分析和比较PC与化疗在亚洲患者的疗效和安全性,与IIIb-IV期NSCLC.
- 提供基于第三阶段RCT的最新证据.
主要方法:
- 对第3阶段RCT的六个数据库进行系统搜索.
- 纳入标准:亚洲患者患有IIIb-IV期NSCLC,将PC与化疗进行比较.
- 主要终点:总体生存率 (OS) 和无进展生存率 (PFS).
主要成果:
- 分析了16个RCT,其中包括4,452名亚洲患者.
- 与单独化疗相比,PC显著改善了OS (HR:0.68) 和PFS (HR:0.50).
- 专家还显示了更高的客观反应率 (RR: 1.62) 和疾病控制率 (RR: 1.09).

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.

Tumor Immunotherapy
1.7K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Combination Therapies and Personalized Medicine

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.
