Long-term recurrence in nonfunctional pituitary adenomas after surgery

Microscopic Transsphenoidal Surgery for Pituitary Adenomas in Children and Adolescents

Background & Aim: We described the presentation, management and subsequent treatment outcomes of children and adolescents diagnosed with a pituitary adenoma in a joint neuroendocrine setting followed up by a single service as well as assessing long-term outcomes in terms of endocrine status and neurology symptoms. Methods & Materials/Patients: A total of 21 participants with histologically v...

Increase in folate receptor alpha expression in nonfunctional pituitary adenomas.

AIM Human pituitary adenomas account for 10% of intracranial tumours and occur in about 20% of the population. They cause hypopituitarism or the compression of adjacent regional structures. However, little is known about the molecular pathogenesis that contributes to the development of these tumours. MATERIAL AND METHODS In this study, we investigated the relationship between the expression l...

Management of Pituitary Adenomas: Mononostril Endoscopic Transsphenoidal Surgery

Introduction: The endoscopic transsphenoidal approach for pituitary adenomas and other sellar lesions is quickly becoming the procedure of choice in their surgical management. The most common approach is binostril three-hand technique which requires a large exposure and subjects both nasal cavities to potential trauma. To reduce nasal morbidity, we employ a mononostril two-hand technique with t...

Nonfunctioning giant pituitary adenomas: Invasiveness and recurrence

BACKGROUND We report our surgical series of 35 patients with giant nonfunctioning pituitary adenomas (GNFPA). We analyzed the rule of Ki-67 antigen expression in predicting recurrence. METHODS Thirty-five patients were operated between 2000 and 2010. Suprassellar extension of the tumors were classified according to Hardy and Mohr based on magnetic resonance (MR) studies. Pituitary endocrine f...
