概括
使用免疫疗法和化疗的新型转化疗法在患有晚期肺状细胞癌和罕见的EGFR外因子20插入的患者中实现了完全的反应. 这一策略对具有类似突变的非小细胞肺癌患者有希望.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 基因组学就是基因组学.
背景情况:
- 晚期肺状细胞癌 (SCC) 提出了重大治疗挑战,特别是在罕见的基因突变中,如EGFR外20插入.
- 同时高PD-L1表达可以影响治疗对免疫疗法的反应.
研究的目的:
- 详细介绍一种创新的转化疗法策略,用于晚期肺SCC,具有罕见的EGFR外基子20插入和高PD-L1表达.
- 评估新辅助免疫疗法加化疗在实现病理完整反应 (pCR) 中的疗效.
主要方法:
- 一名58岁的男性患者患有cT4N1M1b阶段的肺部SCC,通过PET/CT,支气管镜和下一代测序进行了诊断.
- 该患者接受了四次-帕克利塔塞尔化疗,并与布罗利祖马布 (抗PD-1免疫疗法) 结合.
- 进行了救援肺部手术,随后进行了辅助免疫疗法.
主要成果:
- 手术前的治疗导致了显著的原发性瘤缩和上腺瘤扩散的解决.
- 患者在手术后获得了病理完整反应 (pCR).
- 在9.4个月的随访期间,没有观察到疾病复发或与免疫相关的不良事件.
结论:
- 术前免疫疗法加化学疗法可以成为非小细胞肺癌 (NSCLC) 的有效转化疗法,这种癌症罕见地存在EGFR外基子20插入.
- 这种方法在一个具有挑战性的NSCLC病例中显示出实现pCR和持久缓解的潜力.
- 需要进一步的研究,以探索这种策略在更广泛的患者群体中的价值和挑战.

01:27Tumor Immunotherapy
480
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.

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...

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.

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
