概括
将向放射性干疗法 (RL) 与免疫疗法相结合显示出有希望的结果. 优化RL时间和放射性核素半衰期可以改善免疫细胞活力并提高治疗效率,以获得更好的临床结果.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 放射化学 放射化学是指辐射化学.
背景情况:
- 外部束辐射疗法 (EBRT) 与免疫疗法相结合,通过诱导免疫细胞死亡 (ICD) 和激活免疫系统,已经显示出临床前的前景.
- 结合EBRT和免疫疗法的临床结果经常令人失望.
- 放射性干疗法 (RL) 与EBRT相比具有优势,包括同时治疗多种瘤,但将其与免疫疗法结合起来,由于潜在的免疫细胞损伤和旁观者效应,会带来挑战.
研究的目的:
- 探索优化放射性干疗法 (RL) 和免疫疗法组合的策略.
- 解决与结合RL和免疫疗法相关的挑战,例如免疫细胞毒性和旁观者效应.
- 确定关键因素,包括时间和放射性核素选择,以增强RL和免疫治疗之间的协同作用.
主要方法:
- 对放射治疗和免疫治疗组合的临床前和临床数据的审查.
- 对RL和免疫治疗的作用机制的分析.
- 评估辐射暴露对免疫细胞和效应器功能的影响.
- 在免疫疗法协同作用的背景下,考虑放射性核酸的特性,包括半衰期和排放特征.
主要成果:
- 临床前研究表明RL可以诱导免疫细胞死亡 (ICD),释放损伤相关分子模式 (DAMPs) 和细胞因子来激活免疫系统.
- 将外部束辐射疗法 (EBRT) 与免疫疗法结合的临床结果往往令人失望.
- 在RL-免疫疗法组合的挑战包括从长时间的辐射暴露和"交叉火"或"旁观者"影响损害效应细胞对免疫细胞的潜在损伤.
结论:
- 优化免疫治疗的时间,可能在RL治疗后几周,可以减轻辐射诱导的免疫细胞损伤.
- 选择具有较短半衰期的放射性核素可以最大限度地降低免疫细胞的毒性,同时保持杀伤瘤的有效性.
- 未来的RL疗法应优先考虑具有最佳排放概况和半衰期的放射性核素,以最大限度地提高与免疫疗法的协同作用,并改善临床结果.

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.

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.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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.

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...
