概括
与历史数据相比,用向治疗加上阿特佐利祖马布治疗无塑性甲状腺癌 (ATC) 的治疗改善了整体存活率 (OS). 在这项研究中,BRAF V600E突变瘤显示了最长的生存期.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 临床试验 临床试验
背景情况:
- 无塑性甲状腺癌 (ATC) 是一种罕见的,致命的癌症,治疗选择有限.
- 目前的治疗方法预后不好,特别是对于非BRAF突变瘤.
- 向疗法看起来很有前途,但需要结合策略才能获得最佳结果.
研究的目的:
- 评估匹配向治疗与ATC患者的免疫检查点抑制剂相结合的疗效.
- 为了确定这种组合是否与历史对照相比改善整体存活率 (OS).
主要方法:
- 一个第二阶段的单中心试验招募了43名全身疗法原始的ATC患者.
- 患者接受了阿特佐利祖马布加上基于瘤突变状态的向治疗:BRAF V600E (队列1),RAS/NF1/2 (队列2),或非BRAF/RAS/NF1/2 (队列3).
- 主要结局是整个队列的中位数OS,与5个月的历史中位数OS相比.
主要成果:

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.

Tumor Immunotherapy
486
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.
