Cancer immunotherapy has transformed oncology, with CAR-T cell therapy emerging as a cornerstone of personalized treatment for hematologic malignancies. In China, rapid advancements in domestically developed CAR-T therapies have achieved clinical outcomes comparable to global benchmarks, with overall response rates (ORR) of 79-89% in B-cell malignancies and 64% 12-month progression-free survival in multiple myeloma. Despite these successes, CAR-T application in solid tumors remains hindered by antigen heterogeneity, immunosuppressive microenvironments, and on-target/off-tumor toxicity. To address these barriers, China has pioneered innovative strategies, including dual-target CAR-T constructs, armored CAR-Ts secreting immunomodulatory cytokines, and synergistic integration with traditional Chinese medicine, which enhances CAR-T efficacy by inhibiting myeloid-derived suppressor cells and reducing cytokine release syndrome. Notably, preclinical studies demonstrate that Huangqin increases tumor regression rates from 40 to 65% in lung cancer models when combined with CAR-T therapy. Concurrently, China is reshaping accessibility through policy innovations such as the "1 + 3 + N" multi-tiered payment system and regional insurance pilots, which reduce patient costs by 50%. Strategic investments in automated manufacturing and global regulatory harmonization further position China as a leader in cost-effective CAR-T development. However, challenges persist in solid tumor targeting, international market integration, and long-term safety monitoring. Future directions emphasize precision engineering, AI-driven treatment optimization, and cross-border collaborations to advance next-generation therapies. By balancing innovation, affordability, and policy agility, China is poised to drive the global evolution of cancer immunotherapy while addressing unmet needs in both hematologic and solid malignancies.
