概括
将树突细胞细胞因子杀手 (DC-CIK) 免疫疗法与微波切除 (MWA) 结合起来,可显著减少早期肝细胞癌 (HCC) 患者的复发并延长无疾病生存期. 这种方法提供了更好的结果,特别是对于特定的患者子组.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 肝细胞癌研究 肝细胞癌研究
背景情况:
- 国际指导方针建议局部切除作为早期肝细胞癌 (HCC) 的首要治疗方法.
- 微波切除 (MWA) 是一种常见的HCC局部切除技术.
- 将MWA与免疫疗法结合的潜在协同效应需要进一步研究.
研究的目的:
- 评估树突细胞细胞因子杀手 (DC-CIK) 免疫疗法和MWA在早期HCC患者的联合抗瘤疗效.
- 评估这种联合治疗对瘤结果和免疫状况的影响.
主要方法:
- 一项回顾性研究涉及1,141名患有美国联合癌症委员会I-II期HCC的患者,他们接受了MWA治疗.
- 免疫治疗组 (40名患者) 接受了MWA加DC-CIK,而对照组 (1,101名患者) 仅接受了MWA.
- 倾向性得分匹配 (PSM) 用于平衡患者特征;分析了瘤学结果和免疫标志物.
主要成果:
- 在DC-CIK加MWA组中,对于原发性和复发性HCC,无病生存期 (DFS) 显著延长.
- 与单独使用MWA相比,免疫疗法组的复发频率减少,复发间隔延长.
- 特定的子组 (年龄 ≤ 60,中度差异化的HCC,HBV联合感染) 显示出显著的DFS益处;治疗后观察到CD3+和CD8/CD28+水平升高.
结论:
- 结合DC-CIK免疫疗法与MWA的联合治疗显著改善了DFS,并减少了早期HCC的复发率.
- 这些益处在60岁以下的患者,中度差异化的HCC患者或与HBV同时感染的患者中尤为明显.
- 这种综合方法调节免疫状态,表明免疫疗法在提高HCC的MWA有效性方面发挥了作用.

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.

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
