Objectives: To describe the metabolic and surgical outcomes of adult patients with craniopharyngioma undergoing extended transsphenoidal surgery (ETS). Secondary: to compare surgical outcomes with patients undergoing conventional transcranial surgery (CTS).Methods: Retrospective observational study. Adult patients with craniopharyngiomas undergoing ETS between 2015 and 2020 were included. Descriptive analysis was performed by obtaining median and quartil...

Introduction: Endoscopic transsphenoidal pituitary surgery has become the first line method for removal pituitary tumours. A new way to see the surgical field and the cooperation of two neurosurgeons has supposed a revolution in the area.Objetives: Analyse surgical outcomes and complications of a cohort of patients from a single center who underwent ETPS for Cushing disease.Methods: Descriptive prospective-retrospective study inclu...

Introduction: Pituitary abscess (PA) is a rare condition, representing less than 1% of pituitary lessions. Only around 200 cases have been reported in the scientific literature. Preoperative diagnosis is often challenging due to nonspecific clinical and radiological manifestations.Materials and methods: Retrospective descriptive cohort study. We analyze demographic and clinical variables, hormonal involvement, recurrence, type of surgery and antibiotic t...

Methods: Descriptive retrospective study among patients who underwent ETPS for ACTH-secreting pituitary adenomas performed by the same surgical team from January/2013 to January/2017.Results: 27 ACTH-secreting pituitary adenomas operated via ETPS. 20 (74.1%) were women, median age at surgery was 43.25 [29.65–61.59] years and median follow-up was 3.13 [1.6–6.69] years. Presurgically, 25 (92.59%) patients recieved drugs for control cortisol hyper...

Methods: We conducted a retrospective descriptive study including 67 patients with non-functioning pituitary adenomas surgicaly removed via ETPS beetwen January/2013 to January/2017.Results: Among 67 patients with non-functioning pituitary adenomas surgicaly removed via ETPS 44 (65.67%) were men. 52 (77.61%) patients recieved their first surgery, 14 (20.9%) had been operated one time before and 1 (1.49%) had been operated two times. Every patient reopera...

Methods: Descriptive retrospective study of the clinical outcomes and RNA expression in aggressive pituitary tumors treated with temozolomide. RNA expression was studied in tumor samples normalized to housekeeping genes including GH, POMC, PRL, αsub, FSH, LH, TSH, sst1, sst2, sst3, sst5, sst5b, sst5c, DR1, DR2T, DR2L, DR4, DR5, Ghrelin, In1-Ghrelin, GOAT, GHRR1b, AVPR1b, GHRH-R, GnRH-R, Ki-67, PTTG1, CRHR1.Results: Ten patients were treated. 30% (3)...

Pituitary adenomas are usually benign. However, a significant number of pituitary adenomas show an aggressive behaviour, with local invasion, increased risk of recurrence after surgery and lack of therapeutic response. In this study, we aimed to determine whether invasive and non-invasive pituitary adenomas display differences in clinical features and molecular parameters. In this retrospective descriptive study, 46 pituitary adenomas were analysed. Invasiveness was defined as...

Methods: Restrospective descriptive study of patients who underwent ETPS for pituitary adenoma removal performed by the same surgical team in Virgen del Rocio Hospital of Seville from January 2014 to January 2019.Results: 174 patients had a pituitary adenoma (44 GH, 36 ACTH, 94 Non functioning). 54.02% were female. In acromegaly, 39 (88.63%) patients were operated by ETPS as initial approach. 20 (51.28%) patients had cavernous sinus invation. At outcome ...

Aim: To assess whether E-cadherin expression levels in somatotropinomas were associated with the response to somatostatin analogues (SSAs) therapy in patients with acromegaly.Methods: In this retrospective study, 56 acromegaly patients that underwent transsphenoidal surgery were evaluated. All patients were treated preoperatively with SSAs (octreotide or lanreotide) for at least 6 months. Responsiveness to SSAs was evaluated by percent IGF-1 reduction af...
