概括

立体体辐射疗法 (SBRT) 对不可切除的肝外胆道管癌具有前景,比传统分离放射疗法 (CFRT) 提供更好的局部控制. 然而,没有选择性节点辐射的SBRT可能会增加区域性故障,需要进一步研究.

科学领域:

在瘤学瘤学.
辐射瘤学辐射瘤学
手术瘤学手术瘤学

背景情况:

放射疗法 (RT) 是不可切除的肝外胆管癌的标准治疗方法.
评估不同的RT技术对于改善患者的治疗结果至关重要.

研究的目的:

为了比较常规分离放射治疗 (CFRT) 和立体体辐射疗法 (SBRT) 对于不可切除的肝外胆管癌的疗效.
评估两种RT技术之间的局部控制,区域控制和生存率.

主要方法:

对18名无法切除的肝外胆管癌患者进行了回顾性分析,这些患者接受了CFRT或SBRT治疗.
CFRT组接受了选择性节点辐射 (ENI);SBRT组没有.

主要成果:

与CFRT (p=0.041) 相比,SBRT表现出优越的局部控制 (12.5%与60.0%的失败)
CFRT显示区域控制更好 (20.0%对62.5%的失败) (p=0.047).
年龄较小 (≤55岁) 与改善的整体存活率,局部区域无衰竭存活率和远程无转移存活率相关.

结论:

虽然SBRT可以增强局部瘤控制,但由于缺乏ENI,它会增加区域性复发的风险.
需要进行前性研究,以调查低分离ENI与SBRT的整合,以提高安全性和有效性.

Targeted Cancer Therapies

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.
There are several types of targeted therapies against specific...

Tumor Immunotherapy

Tumor Immunotherapy

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.
