CAR-T 细胞疗法已在多种B细胞恶性肿瘤的治疗中确立地位。然而,由于肿瘤间及肿瘤内异质性以及免疫抑制性微环境,将这一治疗效果转化应用于实体瘤一直面临挑战。局部干预手段,如手术、放疗、局部消融和局部区域药物递送,可通过改善肿瘤浸润和降低全身毒性来增强CAR-T 细胞疗法在实体瘤中的效果。此外,消融和放疗已被证明可通过远隔效应对全身免疫应答进行(再)激活,并在物理、细胞和化学层面重编程肿瘤微环境。本综述重点阐述了联合方法克服CAR-T 细胞疗法障碍的潜在协同作用,并总结了可能为新的治疗方案铺平道路的近期研究。
Chimeric antigen receptor T cell therapy has been established in the treatment of various B cell malignancies.
However, translating this therapeutic effect to treat solid tumors has been challenging because of their inter-tumoral as well as intratumoral heterogeneity and immunosuppressive microenvironment. Local interventions, such as surgery, radiotherapy, local ablation, and locoregional drug delivery, can enhance chimeric antigen receptor T cell therapy in solid tumors by improving tumor infiltration and reducing systemic toxicities.
Additionally, ablation and radiotherapy have proven to (re-)activate systemic immune responses via abscopal effects and reprogram the tumor microenvironment on a physical, cellular, and chemical level. This review highlights the potential synergy of the combined approaches to overcome barriers of chimeric antigen receptor T cell therapy and summarizes recent studies that may pave the way for new treatment regimens.
