近年来,自体CAR-T 细胞治疗白血病和淋巴瘤取得突破,可使部分患者获得持久缓解。多项已批准的CAR-T 治疗试验(包括本中心试验)显示,在既往多线化疗或靶向治疗后疾病进展的患者中,约40%出现客观肿瘤消退。但并非所有患者均有应答,复发也较常见。因此,识别用于追踪CAR-T 临床活性及预测患者选择的生物标志物,对发展个体化细胞治疗至关重要。患者的应答程度和持续时间各不相同,提升持久缓解率是CAR-T 实现其治疗潜力的关键。疗效不仅取决于靶向恶性细胞常表达的抗原(如CD19、BCMA),也受输注CAR-T 细胞体内持续性差、迁移能力有限等因素制约。需要识别有利于CAR-T 细胞归巢至靶部位并长期存续、持续监视肿瘤的因素。目前,对于为何部分白血病和淋巴瘤患者在CAR-T 输注后获得完全且持久的抗肿瘤反应,而另一些患者仅部分应答后复发或完全无应答,认识仍不全面。确定促进CAR-T 细胞靶向归巢和长期持续的细胞及分子因素,有助于改进针对淋巴瘤及其他恶性肿瘤的CAR-T 治疗。
In recent years we have witnessed a breakthrough in the treatment of leukemia and lymphoma using autologous CAR-T cells that can induce durable remission in patients. Multiple approved CAR-T therapy trials, including those at our centre, have consistently yielded objective tumor regression rates in about 40% of patients that have progressed after multiple previous chemo or targeted therapies. However, not all the patients respond to the therapy and rate of relapse is unfortunately common. Hence, the identification of biomarkers to track clinical activity of CAR-T and as predictive tools for patient selection is critical in our quest to develop personalized cellular therapies, where both degree and duration of response varies among different patients. For CAR-T therapy to truly live up to its promise, it is imperative to increase durable response rates. The success of CAR-T therapy not only depends in targeting antigens (e.x. CD19, BCMA) commonly expressed by malignant cells but also limited by poor persistence and trafficking of infused CAR-T cells in vivo. Hence highlighting the need to identify factors that exhibit optimal homing to the target sites and are able to persist long-term for continuous tumor surveillance. Furthermore, we lack comprehensive knowledge on how certain patients with leukemia and lymphoma achieve complete durable anti-cancer response upon CAR-T infusion whereas other either partially respond to the therapy and then relapse, or do not respond at all. Determining cellular and molecular factors that contribute to optimal homing of CAR-T cell to target sites as well as their long-term persistence will help us to design improved CAR-T based therapy against lymphoma other malignancies.
