概括
采用瘤透性淋巴细胞 (TIL) 结合化疗的采用细胞疗法在上皮卵巢癌 (EOC) 中表现有前途. 这种方法可以安全地降低免疫抑制,从而导致高客观反应率,并改善了一些患者的无进展生存率.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 癌症研究 癌症研究
背景情况:
- 表皮卵巢癌 (EOC) 呈现与积极结果相关的T细胞透和与不良结果相关的髓状细胞透.
- 瘤透淋巴细胞 (TIL) 疗法是EOC的潜在治疗方法,但需要减少来自骨髓细胞衍生的抑制细胞和M2巨细胞的免疫抑制.
- 基于的化疗可以减少免疫抑制,为基于T细胞的免疫治疗创造机会.
研究的目的:
- 评估使用TIL采用细胞疗法的可行性和安全性,在白金基化疗期间,在患有复发性白金敏感性EOC的患者中进行.
- 评估TIL治疗与化疗结合的临床反应和免疫调节效应,有或没有干扰素-α (IFNα).
主要方法:
- 一个I/II期试验 (NCT04072263) 招募了患有复发性白金敏感性EOC的患者.
- 在化疗后的周期中,TILs被管理,患者被分层分为接受IFNα或不接受IFNα的队列.
- 可行性,安全性,临床反应和免疫调节被评估为主要和次要终点.
主要成果:
- 对所有患者来说,TIL扩张成功.
- 与没有IFNα的化疗相结合的TIL治疗是安全的;然而,添加IFNα增加了毒性,特别是血小板缩小.
- 观察到的客观应答率为86% (3CR,9PR,2SD),其中两名患者的无进展生存时间超过了他们之前的无间隔.
结论:
- TIL治疗可以安全地与基于的化疗相结合,但不能与IFNα.
- 化疗有效降低免疫抑制,表明化疗期间适当时机的TIL输液,可能与IL-2支持,可能是EOC的新治疗方法.

Tumor Immunotherapy
533
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.

Targeted Cancer Therapies

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.
