Targeted radiation zaps returning brain tumors in early trial

This study tested a special type of radiation therapy called boron neutron capture therapy (BNCT) for people whose meningioma (a brain tumor) came back after prior treatment. Ten adults aged 20 and older received an injection of a boron compound (B10 L-BPA) followed by neutron beam exposure to destroy tumor cells. The goal was to see if the treatment is safe and can shrink or control the tumor. Since meningioma can recur and patients may need ongoing monitoring, this is classified as disease control rather than a cure.
