概括

对于结肠直肠癌肝转移的-90放射栓塞 (TARE) 将免疫反应转移到抗瘤形状. 这项研究观察到细胞因子和T细胞的有利变化,支持TARE与免疫治疗结合.

科学领域:

免疫学免疫学免疫学
在瘤学瘤学.
放射学放射学是一门学科.

背景情况:

结肠直肠癌肝脏转移 (CLM) 是一个重大的临床挑战.
-90放射栓塞 (TARE) 是一种治疗CLM的方法.
目前尚不完全了解TARE的免疫调节作用.

研究的目的:

为了前性地研究CLM的TARE后免疫学变化.
分析循环中的细胞因子水平和免疫细胞子集频率.

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.

Biological Effects of Radiation

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
