概括
在IIIA阶段的黑色素瘤中,辅助免疫治疗的使用有所不同,学术和大批量中心的处方较少. 这种减少的使用没有影响患者的存活率,这表明在早期黑色素瘤中可能有更有选择性的免疫疗法应用.
科学领域:
- 在瘤学瘤学.
- 黑色素瘤研究 黑色素瘤研究
- 免疫治疗是一种免疫疗法.
背景情况:
- 辅助免疫疗法已被批准用于III期黑色素瘤,但对IIIA早期疾病的生存益处数据有限.
- 目前在IIIA阶段黑色素瘤中辅助免疫治疗的指导方针依赖于临床判断,导致处方变化.
- 这项研究调查了与IIIA阶段黑色素瘤辅助免疫疗法相关的实践变化和患者结果.
研究的目的:
- 描述IIIA阶段黑色素瘤的辅助免疫治疗处方模式的当前变化.
- 根据不同的免疫疗法处方实践,比较患者的结果,特别是总体存活率.
- 确定影响IIIA阶段黑色素瘤患者使用辅助免疫疗法的因素.
主要方法:
- 从国家癌症数据库对2015-2019年间诊断的4432名IIIA阶段黑色素瘤患者的回顾性分析.
- 利用多变量Cox比例危险回归来比较不同治疗组的整体存活率.
- 确定了与接受辅助免疫疗法相关的因素,包括治疗中心类型和体积.
主要成果:
- 34%的合格患者接受了辅助免疫疗法.
- 与社区或低体积中心相比,在学术或高体积中心治疗的患者接受免疫治疗的几率较低.
- 接收免疫疗法与整体存活率没有显著关联 (p=0.095),而高容量中心显示存活率有所改善 (HR=0.52,p=0.030).
结论:
- 学术和高体量中心在IIIA阶段黑色素瘤中使用辅助免疫疗法比社区和低体量中心少.

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.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.

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...
