Introduction: Parathyroid tumors are the most common (90%) and usually the first manifestation feature of MEN1 syndrome. The occurrence of anterior pituitary tumors in MEN1 syndrome may range between 10% and 60%. Pituitary involvement includes the initial manifestation of MEN1 syndrome in 10% to 25% of individuals and usually show more aggressive behavior; 20% secrete prolactin, fewer than 10% secrete GH, 5% secrete ACTH, and the remainder appear to ...

Introduction and objective: Clinically nonfunctional pituitary adenomas are relatively an uncommon disease. The aim of this work is to describe the clinical characteristics and to review the results of transsphenoidal surgery (TS) of pituitary adenomas in a reference centre.Methods: A retrospective study (1995–2014) of 66 patients (50% men) diagnosed with pituitary adenomas by a magnetic resonance imaging (MRI) was conducted. demographic, clinical, ...

Introduction: Surgery is the primary therapy in most acromelagic patients. When persistent disease is observed, adjuvant medical therapy is used. Pasireotide is a somatostatin analogue (SSA) not approved for acromegaly therapy yet, but with a potentially better response, given that it binds to four out of five somatostatin receptors.Materials and methods: We present the case of an acromegalic patient with resistance to many therapies and response to trea...

Primary lymphomas of the thyroid are uncommon tumours, constituting fewer than 2% of all thyroid malignancies. For this reason their clinical features are not very well known. It seems that most of them arise in patients who have chronic autoimmune thyroiditis.From our patients with primary thyroid cancer since 1995, we selected those with pathological diagnosis of thyroid lymphoma. Epidemiological data, clinical features and response to treatment were a...

Context: There is no data on mortality of acromegaly diagnosed in the elderly. Objective: To compare clinical characteristics, GH-related comorbidities, therapeutic approaches and mortality of patients diagnosed before or after 2010 and to assess overall mortality compared with the general Spanish population. Setting: Spanish tertiary care centers.Design, Patients, and Methods: Retrospective evaluation of 118...

In our country, as in others, there is a lack of data on the success rate of transsphenoidal surgery for producing pituitary adenomas. We evaluated the results reported in TESSPAIN, a retrospective multicenter nationwide project that includes all the TSS performed in the participating centers in the period between 2018 and 2022, both included. Surgical treatment success is defined according to the published criteria for each disease: normal IGF-1 and GH after 75 g of oral gluc...

Objective: To evaluate the natural history of Rathke’s cleft cysts (RCC).Materials and Methods: A multicenter retrospective clinical practice study of adult patients with radiologically diagnosed RCCs since 2000 in 15 tertiary hospitals (SPAIN-QBR study) with a diameter greater than 5 mm, in whom non-surgical follow-up was decided.Results: A total of 177 patients were followed for 65.8 ± 42.3 months. The mean age was 42.8...

Aim: To evaluate the efficacy of transsphenoidal surgery in patients with Rathke cleft cysts (RCCs), and recurrence rates after follow-upMethods: A multicenter retrospective clinical practice study in patients with RCCs operated through transsphenoidal route and followed in 15 tertiary hospitals (SPAIN-QBR study) during 64.0 ± 49.0 months.Results: A total of 85 patients with a diagnosis of RCCs underwent transsphenoidal surger...

Surgical factors, in particular a higher volume of operations and a dedicated neurosurgeon, are considered the main determinants of surgical complication rates in transsphenoidal surgery (TSS). We evaluated postoperative complications in a large series of TSS for non-producing adenomas included in TESSPAIN, a retrospective multicenter nationwide registry. All TSS performed at the 29 participating centers between 2018 and 2022 were included. Globally, 1421 non-producing pituita...

Aim: To investigate the impact of pituitary surgery on glucose metabolism and to identify predictors of diabetes remission after surgery in patients with acromegaly.Methods: A national multicenter retrospective study of acromegaly patients undergoing transsphenoidal surgery for the first time at 33 tertiary Spanish hospitals (ACRO-SPAIN study, n=604) was performed. Surgical remission was evaluated according to the 2000 and 2010 criteria. Glucose...
