Exploring Targeted Delivery Systems for Boron Neutron Capture Therapy and Its Potential as a Promising Therapeutic Modality for Hepatocellular Carcinoma.

BACKGROUND: Boron neutron capture therapy (BNCT) is a precision binary radiotherapy. In this modality, thermal neutrons combine with 10B to induce a nuclear reaction that kills tumor cells. Its therapeutic efficacy depends on the targeted accumulation of boron delivery agents. BNCT has demonstrated clinical efficacy in treating head and neck cancers and recurrent gliomas. However, there is limited evidence regarding its application in hepatocellular carcinoma (HCC). This review systematically examines recent advances in novel boron carriers. It also assesses the potential of BNCT for treating HCC and aims to provide a new therapeutic option for HCC.

METHODS: We used a systematic research approach to investigate the latest advances in novel boron carrier development. We also analyzed existing clinical data related to BNCT treatment for HCC. We aimed to systematically assess the feasibility and potential of applying BNCT to HCC.

RESULTS: Newly designed boron carriers show significantly enhanced targeted aggregation within tumor cells and reduced systemic toxicity compared to traditional carriers. Preliminary clinical studies have confirmed the potential efficacy of BNCT in inhibiting HCC growth. Notably, BNCT possesses the unique advantage of precise tumor targeting, which shows promising potential in minimizing damage to surrounding normal liver tissue.

CONCLUSION: The progress made in the development of boron carriers has built a solid foundation for improving the efficacy and safety of BNCT treatment for HCC. By addressing current limitations in boron delivery and clinical evidence, BNCT has the potential to complement existing treatment modalities, improve outcomes for HCC patients, and provide new directions for the clinical treatment of HCC.
