Unveiling Cellular Responses and Underlying Immune Effects Induced by Boron Neutron Capture Therapy.

Abstract

Boron neutron capture therapy (BNCT) is an emerging modality for cancer treatment. Although its concept was proposed in the last century, progress has been relatively slow because limitations in neutron source technology and boron compounds. In recent years, with the increased availability of neutron devices and improvements in boron compounds, the radiobiological effects of BNCT have been investigated more deeply, leading to a surge of research findings in the field. Therefore, a systematic review of the current status of BNCT is particularly warranted. In this review, we integrate the latest studies to provide a comprehensive and detailed description of the direct and indirect mechanisms by which BNCT induces cell killing, as well as the subsequent cellular responses. More importantly, we propose that BNCT exhibits a stronger immunologic foundation and immunogenicity than traditional radiation therapy, indicating significant potential for its combined application with immunotherapy. These results offer a robust theoretical foundation for the future clinical use of BNCT and indicate that continued investigation of BNCT in conjunction with immunotherapy may pave the way for more advanced cancer treatment strategies.
