胶质母细胞瘤仍是成人中最具侵袭性的原发性脑肿瘤之一,尽管采用多模式治疗,生存期也很少超过 15 个月。
胶质母细胞瘤仍是成人中最具侵袭性的原发性脑肿瘤之一,尽管采用多模式治疗,生存期也很少超过15个月。新型免疫治疗策略,尤其是CAR-T 细胞疗法,已成为克服传统治疗局限性的有前景的方法。本综述总结了近期探索局部区域CAR-T 细胞递送治疗复发性胶质母细胞瘤的早期临床试验,并强调了参与这一不断演进的治疗范式的多学科神经肿瘤团队的关键考量。瘤内、腔内、脑室内或联合递送途径的I期研究已证实技术可行性和安全性,大多数不良事件可控。双途径递送可能增强CAR-T 细胞的分布,并在部分患者中产生早期影像学和临床缓解。然而,治疗持久性仍受肿瘤异质性、抗原丢失和免疫抑制性肿瘤微环境的限制。多学科诊疗团队在导管和储液囊置入、输注计划以及神经炎症毒性管理方面发挥着关键作用。尽管当前研究结果尚属初步,但靶点选择、给药策略和联合治疗的持续优化可能扩大复发性胶质母细胞瘤的治疗选择,并进一步将免疫治疗整合到当代神经肿瘤诊疗中。
Glioblastoma remains one of the most aggressive primary brain tumors in adults, with a survival rarely exceeding 15 months despite multimodal therapy. Novel immunotherapeutic strategies, particularly chimeric antigen receptor T-cell therapy, have emerged as promising approaches to overcome the limitations of conventional treatments. This review summarizes recent early-phase clinical trials investigating locoregional chimeric antigen receptor T-cell delivery in recurrent glioblastoma and highlights key considerations for multidisciplinary neuro-oncology teams involved in this evolving therapeutic paradigm. Phase I studies of intratumoral, intracavitary, intraventricular, or combined delivery routes have demonstrated technical feasibility and safety, with most adverse events being manageable. Dual-route delivery may enhance chimeric antigen receptor T-cell distribution and produce early radiographic and clinical responses in selected patients. However, therapeutic durability remains limited by tumor heterogeneity, antigen loss, and the immunosuppressive tumor microenvironment. Multidisciplinary care teams play a critical role in catheter and reservoir placement, infusion planning, and management of neuroinflammatory toxicities. Although current findings are preliminary, ongoing optimization of target selection, dosing strategies, and combination therapies may expand treatment options for recurrent glioblastoma and further integrate immunotherapy into contemporary neuro-oncology care.
