    Boron neutron capture therapy (BNCT) selectively kills tumor cells while sparing normal tissues, utilizing a nuclear reaction between boron-10 and neutrons.

  • 2

    BNCT has shown clinical potential in treating recurrent and radioresistant cancers, with promising results reported in various tumor types.

  • 3

    Emerging evidence indicates that BNCT can induce bystander and abscopal effects, affecting non-irradiated cells and distant tumors.

  • 4

    The bystander effect involves biological responses in non-irradiated cells due to signals from irradiated neighbors, while the abscopal effect describes distant tumor regression.

  • 5

    Integrating BNCT with immunotherapy may enhance systemic antitumor immune responses, linking localized treatment effects to broader immune mechanisms.
