- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 神经瘤学神经瘤学
背景情况:
- 免疫检查点抑制剂 (ICI) 是一种越来越多的治疗各种癌症,包括大脑转移 (BM).
- 在ICI治疗下,一小部分患者经历了悖论性的瘤生长,称为超渐进性疾病 (HPD).
研究的目的:
- 在接受ICI的脑转移患者中调查HPD的发生率.
- 分析BM患者ICI启动前后的瘤生长率.
主要方法:
- 对60名患有非小细胞肺癌或黑色素瘤的BMs患者的回顾性图表审查,这些患者接受了ICI治疗.
- 在ICI启动之前和之后评估了瘤体积.
- HPD定义为免疫治疗后的瘤生长率,在三个月内超过免疫治疗前的两倍.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:27Tumor Immunotherapy
464
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.
