概括
免疫检查点抑制剂正在改变子宫内膜癌的治疗方法. 在病情进展后,重新挑战患者使用这些疗法是有希望的,特别是在不匹配的修复缺陷瘤中,但需要进一步研究最佳策略.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 妇科癌症 妇科癌症
背景情况:
- 免疫检查点抑制剂 (ICI) 现在是晚期/复发性子宫内膜癌的标准,特别是不匹配修复缺陷 (dMMR) 类型.
- 在初始ICI治疗后的疾病进展是一个临床挑战,前性指导有限.
- 临床实践正在发展,大量患者接受后续的非协议免疫疗法.
研究的目的:
- 审查新出现的证据和免疫检查点抑制剂在子宫内膜癌中重新挑战免疫检查点抑制剂的临床理由.

Tumor Immunotherapy
1.7K
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.

Treatment 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...
