概括
免疫检查点抑制剂对具有EGFR突变的肺形癌 (PPC) 有希望. 这一案例突出了针对性治疗失败后的潜在疗效,即使有严重的副作用.
科学领域:
- 在瘤学瘤学.
- 肺部病理学 肺部病理学
- 免疫治疗是一种免疫疗法.
背景情况:
- 肺形癌 (PPC) 是一种罕见的,具有有限治疗选择的侵袭性肺癌.
- 在EGFR突变的PPC中,免疫检查点抑制剂 (ICI) 的证据很少.
- 在一些PPC病例中注意到高编程死亡连接体1 (PD-L1) 表达.
研究的目的:
- 报告一个用ICI治疗的EGFR突变PPC病例.
- 评估EGFR-TKI抑制剂 (EGFR-TKI) 失效后的ICI的疗效.
- 要突出与免疫相关的不良事件的管理.
主要方法:
- 一个患有晚期PPC和EGFR突变 (L858R + E709K) 的患者的病例报告.
- 治疗包括奥西默蒂尼布 (EGFR-TKI),其次是潘布罗利祖马布 (ICI).
- 诊断证实了手术后的诊断;PD-L1表达高 (95%).
主要成果:
- 布罗利祖马布在EGFR突变的PPC中取得了显著的瘤反应.
- 用普得尼索隆成功治疗3级免疫相关大肠炎.
- 尽管最初出现了不良事件,但完成了六个布罗利祖马布治疗周期.
结论:
- ICI可能是EGFR突变PPC的可行的治疗选择,特别是高PD-L1表达.
- 有效管理与免疫相关的不良事件对于治疗完成至关重要.
- 这一案例扩大了对ICI在挑战肺癌亚型中的实用性的理解.

Mitogens and the Cell Cycle
6.4K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Targeted Cancer Therapies
7.5K
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.
