概括
在新辅助免疫化学疗法 (NICT) 和手术后的辅助免疫疗法 (AIT) 并没有改善所有食道状细胞癌 (ESCC) 患者的生存率. 然而,AIT显著有利于残留淋巴结疾病 (ypT+N+) 的患者.
科学领域:
- 在瘤学瘤学.
- 手术瘤学手术瘤学
- 免疫治疗是一种免疫疗法.
背景情况:
- 辅助免疫疗法 (AIT) 在食道癌症 (EC) 中显示出有前途的前后新辅助化学辐射对于残留疾病.
- 在新辅助免疫化学疗法 (NICT) 之后,在食道状细胞癌 (ESCC) 中进行激进手术后,AIT的必要性仍然不清楚.
研究的目的:
- 评估辅助免疫疗法 (AIT) 对食道状细胞癌 (ESCC) 患者的疗效,这些患者接受了新辅助免疫化学疗法 (NICT),随后进行了激进手术.
- 为了比较ESCC患者的无疾病存活率 (DFS) 和整体存活率 (OS) 在AIT后NICT和手术后和没有AIT之间.
主要方法:
- 对215名ESCC患者的回顾性分析,这些患者在2019年至2020年期间接受了NICT和彻底手术.
- 卡普兰-梅尔曲线被用来比较DFS和OS.
- 考克斯的比例危险模型评估了与DFS和OS相关的参数.
主要成果:
- 在接受AIT (n=78) 和未接受AIT (n=137) 的患者之间,没有观察到3年DFS或OS的显著差异.
- 在残留淋巴结疾病 (ypT+N+) 的患者中,AIT显著改善了DFS (23.9%对38.5%,P=0.036) 和OS (37.0%对61.5%,P=0.010).
- 在患有ypT0N0或ypT+N0疾病的患者中,AIT没有显示出显著的生存益处.
结论:
- 在新辅助免疫化学疗法 (NICT) 和激进手术之后的辅助免疫疗法 (AIT) 在ESCC患者的残留淋巴结参与 (ypT+N+) 中改善了DFS和OS.
- 需要进一步的随机对照试验来验证这些发现,并确定AIT在这个特定的患者亚组中的作用.

Tumor Immunotherapy
394
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.

Cancer Vaccines
237
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
