Objective and design A clinicopathological score has been proposed by Trouillas et al. to
predict the evolution of pituitary adenomas. Aim of our study was to perform an independent …

Pituitary adenomas are currently classified by histological, immunocytochemical and
numerous ultrastructural characteristics lacking unequivocal prognostic correlations. We …

Abstract Background and Objective: In 2004, the World Health Organization defined atypical
pituitary adenomas as those with a Ki-67 expression> 3%, an excessive p53 expression and …

Introduction Usually benign, pituitary tumors (PT) can be invasive and aggressive with a
propensity to progress and/or recur. Trouillas's clinicopathological classification attempts to …

Objective The long-term outcome of non-functioning pituitary adenoma (NFPA) patients is
not clearly established, probably due to the low annual incidence and prolonged natural …

Abstract Objective Pituitary neuroendocrine tumours (PitNET) s can be aggressive, thus
presenting local invasion, postsurgical recurrence and/or resistance to treatment …

Purpose Cavernous sinus invasion by pituitary adenomas is an important prognostic factor
for evaluating the possibilities of complete remission and to guide patient management. A …

Context: The factors associated with pituitary adenoma (PA) growth rate remain unclear.
Objective: The objective of the study was to establish whether the preoperative growth and …

Background Pituitary adenomas are usually considered benign tumours, although some of
them can exhibit an aggressive behaviour. Patients with clinically aggressive pituitary …

Pituitary adenomas (PAs) are benign lesions; nonetheless, some PAs exhibit aggressive
behaviors, which lead to recurrence. The impact of pituitary dysfunction, invasion-related …
