Most head-and-neck cancers that recur locally after prior full-dose conventional radiation therapy respond to Boron Neutron Capture Therapy (BNCT). These results were obtained in a Phase I/II study at the Helsinki University Hospital, Finland. The scientific director of the research program, professor Heikki Joensuu, University of Helsinki, considers the results clinically significant and very interesting. They open a new field for BNCT, since thus far BNCT has been evaluated only in the treatment of some brain tumours.
