Advances in CAR-T Cell Therapy for Solid Tumors

Chimeric Antigen Receptor T (CAR-T) cell therapy represents a groundbreaking advancement in cancer treatment, demonstrating remarkable antitumor efficacy in hematological malignancies. However, despite the substantial clinical progress achieved with CAR-T cell therapy, its application in the treatment of solid tumors remains limited by various factors, including the intricate tumor microenvironment (TME), CAR-T cell exhaustion, CAR-T cell infiltration into tumor tissue, and antigen heterogeneity. Scientists are relentlessly pursuing research in this domain, driven by the aim of offering newfound hope to cancer patients. In this comprehensive review, we delineate the fundamental principles underlying CAR-T cell therapy, delve into the challenges it encounters, and provide an insightful exploration of the advancements and progress made in the application of CAR-T cell therapy for solid tumors.
