sodium borocaptate

(SOH-dee-um BORE-oh-KAP-tayt) A substance used in a type of radiation therapy called boron neutron capture therapy. Sodium borocaptate is injected into a vein and becomes concentrated in tumor cells. The patient then receives radiation treatment with atomic particles called neutrons. The neutrons react with the boron in sodium borocaptate and make radioactive particles that kill the tumor cells without harming normal cells. Also called BSH.
