Background: Pituitary tumours (PT) are generally benign, but they can rarely show an aggressive behaviour, invade surrounding structures and/or grow/recur despite multimodal treatment, making their management extremely challenging. According to the latest guidelines, temozolomide (TMZ) can be an option after failure of standard therapies in aggressive PT, while little data are available on alternative approaches such as peptide receptor radionuclide therapy (PRRT). Herein we r...

Background: Pituitary adenomas in children/adolescents represent around 3% of all intracranial neoplasms. They are more frequently hormone-secreting lesions, usually diagnosed in early childhood and late adolescence. Female gender is generally prevalent, because of most evident symptoms (i.e., irregular periods, galactorrhea, etc.). Giant pituitary adenomas (GA) very rarely occur in pediatric age, posing frequent challenges in their management.Patients a...

Introduction: CyberKnife (CK) is an emerging treatment for pituitary tumours (PT) resistant to other therapies.Patients and methods: We report long-term CK effect on endocrine function and tumour volume in 20 PT patients (11M/10F, mean age 58.6±14.4years). Twelve patients harboured a non functioning adenoma, 2 an ACTH, 5 a GH (one case of TSH co-secretion) and 2 a PRL-secreting PT. Before CK nine patients had normal while 11 presented impaired pitui...
