Abstract

Boron neutron capture therapy (BNCT) holds great promise as a radiochemotherapeutic treatment for various cancers, including malignant melanoma and glioblastoma multiforme. Its appeal lies in the potential for great selectivity in cell killing due to its binary nature. A noncytotoxic compound containing 10B is first introduced to the tumor. Subsequent exposure to an epithermal neutron beam will cause a uniquely efficient neutron capture by 10B. The 11B intermediate undergoes rapid decomposition to an α-particle and recoil lithium atom. The sizeable kinetic energy of these particles (2.8 MeV) is deposited within 10-15 µm, roughly one cell diameter. The two independently manipulable requirements for this therapy allow great precision in treatment of neoplasms.
