Abstract: BACKGROUND: Chimeric antigen receptor T cell therapy is a cutting-edge approach for the treatment of B cell hematological malignancies. These cells efficiently and specifically recognize and kill tumor cells, unrestricted by major histocompatibility complex limitations.
OBJECTIVE: To elucidate the structure, developmental history, and marketed progress of chimeric antigen receptor T cells, summarize their long-term efficacy in B cell hematological malignancies treatments, and discuss associated toxicities, recurrence, and mitigation strategies. Additionally, it reviews the advancement of potential targets in B cell hematological malignancies treatments.
METHODS: Searches were conducted in PubMed, CNKI, and WanFang databases using the terms “CAR-T, B cell hematological malignancies, toxic side effects, immunotherapy” in Chinese and English, focusing on articles regarding chimeric antigen receptor T cell targets in B-cell malignant tumor treatments.
RESULTS AND CONCLUSION: (1) The U.S. Food and Drug Administration and National Medical Products Administration have approved 11 chimeric antigen receptor T cell products, primarily targeting CD19 and B cell maturation antigen targets in B cell hematological malignancies. (2) Long-term follow-up data indicate that chimeric antigen receptor T cell therapy provides a high remission rate and enduring responses in B cell hematological malignancies patients, albeit with recurrence issues due to antigen loss or downregulation. (3) Chimeric antigen receptor T cell therapy is associated with significant toxicities, a high recurrence rate, and drug resistance, constraining its broad application. (4) Future research should concentrate on developing new targets, combined therapies, and strategies to enhance chimeric antigen receptor T cell persistence and antitumor activity.


Key words: B cell hematological malignancies, chimeric antigen receptor T cells, immunotherapy, therapeutic targets, long-term efficacy, toxic side effects, recurrence
