概括
一线免疫检查点抑制剂加上化疗和贝瓦齐祖马布 (IBC) 提供了对HER2改变的肺腺癌的最佳结果. 具有特定瘤免疫微环境特征的患者,包括低PD-1+CD8+T细胞或高CD163+巨细胞,特别受益于IBC.
科学领域:
- 在瘤学瘤学.
- 医学遗传学 医学遗传学
- 免疫治疗是一种免疫疗法.
背景情况:
- 肺腺癌 (2%-4%) 的HER2变化与预后不佳有关.
- 目前的第一线治疗方法 (化疗,贝瓦齐祖马布,免疫检查点抑制剂) 的最佳用途和患者选择尚不清楚.
- 确定 HER2 改变的肺腺癌的最佳疗法至关重要.
研究的目的:
- 评估 HER2 改变的肺腺癌的不同一线治疗方案的疗效.
- 探索瘤免疫微环境 (TIME) 在预测治疗反应中的作用.
- 确定从特定疗法中获益最多的患者子组.
主要方法:
- 来自四个中国癌症中心的第四阶段HER2-改变的肺腺癌患者的回顾性分析.
- 第一线治疗方法的比较:化疗 (C),化疗加贝瓦西祖马布 (BC),免疫检查点抑制剂 (IC) 和IBC.
- 评估无进展生存期 (PFS) 和整体生存期 (OS).
- 对TIME特征 (PD-1+CD8+T细胞,CD163+巨细胞) 的分析.
主要成果:
- 免疫检查点抑制剂加上化疗和贝瓦齐祖马布 (IBC) 证明了最长的中位数PFS和OS.
- 与IC相比,IBC显示脑/骨转移患者的PFS改善.
- 在较年轻的患者,非吸烟者和患有寡聚转移的患者中,IBC比BC提供了显著的好处.
- 患有低PD-1+CD8+T细胞密度或高CD163+巨细胞密度的患者表现出IBC最长的PFS,其次是BC.
结论:
- 一线IBC治疗与在HER2-改变的肺腺癌中具有最佳的疗效有关.
- 具有特定的TIME特征 (低PD-1+CD8+T细胞或高CD163+巨细胞透) 的患者从IBC中获得更大的益处.

Treatment Resistant Cancers
3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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.
