New radiation approach aims to tame pituitary tumors with fewer side effects

This study tested a new way of delivering radiation for people with non-secreting pituitary adenomas that came back or remained after surgery. Instead of a single high dose, the radiation was given in five smaller daily doses. The goal was to see if this approach could control tumor growth while reducing damage to nearby nerves and the pituitary gland. Twenty-five patients were followed for at least a year with MRI scans, eye tests, and hormone checks.
