研究的目的:
- 研究免疫微环境在ccRCC中的作用.
- 开发一个ccRCC预后和免疫治疗反应的预测模型.
主要方法:
- 结合了6个ccRCC队列,并使用ssGSEA量化了53个免疫学术语.
- 用拉索估计和考克斯回归来选五个免疫术语进行预后,以创建免疫相关风险评分 (IRS).
- 使用TIDE和子类映射分析了临床和基因组特征,瘤突变负担 (TMB),拷贝数变异 (CNV) 和免疫治疗反应.
主要成果:

02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

01:27Tumor 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.
