概括
接种流感疫苗可能会降低癌症患者的整体死亡率,特别是那些患有血液癌症的人. 由于可能影响疫苗有效性的混因素,需要进一步研究.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 公共卫生 公共卫生
背景情况:
- 对于免疫功能受损的个人,建议接种流感疫苗,但并非专门针对癌症患者.
- 本研究研究了流感疫苗接种对癌症患者死亡率和其他结果的影响.
研究的目的:
- 研究流感疫苗接种对癌症患者整体死亡率的影响.
- 评估包括流感,肺炎,心肌梗塞,中风,心力衰竭和静脉血栓栓塞等二次结果.
主要方法:
- 一项使用丹麦卫生登记册的全国性队列研究.
- 考克斯的比例危险模型被用来估计调整的危险比率 (aHR) 和95%置信区间 (95%CI).
- 根据癌症类型 (固体瘤与血液瘤) 和年龄 (<65岁与≥65岁) 对患者进行了分层分析.
主要成果:
- 共有75,431名患者 (53,249名固体瘤患者,22,182名血液瘤患者) 接受了长达五个流感季节的随访.
- 在主要分析 (十二月至三月) 中,接种流感疫苗与所有四个子组的总死亡率降低有关.
- 在年轻的血液癌症患者 (aHR,0.66) 观察到的最显著的减少,而最少的是在年轻的固体瘤患者 (aHR,0.91) 观察到的. 敏感性分析显示出不同的结果.
结论:
- 这项研究表明,接种流感疫苗可能会降低免疫功能低下的癌症患者的整体死亡率.
- 由于潜在的未测量混影响疫苗有效性估计,应谨慎解释结果.

Cancer Vaccines

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...

Tumor Immunotherapy
491
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.
