Background: Improved survival rates from brain tumours have resulted in patients living longer with the effects of radiotherapy. Advances in conventional fractionated radiotherapy, such as intensity-modulated radiotherapy (IMRT), enable radiation to be delivered more precisely while partially sparing surrounding structures including the hypothalamic-pituitary axis. Despite these advances, the precise risk of hypopituitarism associated with IMRT in survivors of adult-onset non-...
