Aim: To know if Tg levels after treatment (total thyroidectomy and radioiodine ablation) in the DTC can predict their prognosis in the long term.Material and methods: Basal Tg and Tg after rh-TSH were measured in 229 patients with DTC without any evidence of residual tumour (negative neck ultrasonography) after treatment. The group was followed until tumour recurrence or, if recurrence was not found, a minimum of 12 month (mean ± SD =63±37 mont...

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: The presence of undetectable serum levels of stimulated thyroglobulin (Tg) with negative imaging tests is the criterion used to define remission in low-risk differentiated thyroid cancer (DTC). Most guidelines recommend 131-I ablation after thyroidectomy to remove any possible residual thyroid tissue. Our aim was to know how often undetectable Tg levels are achieved before ablation to avoid unnecessary radiation treatments.Patients and meth...

Introduction: There is no known reliability about an undetectable recombinant human TSH (rhTSH) stimulated serum thyroglobulin (Tg) concentrations, predicts no long-term relapse, or the threshold of it. An rhTSH-stimulated serum Tg determination was made to all patients with DTC that maintained undetectable baseline Tg and negative imaging tests. We correlate their findings with their long-term evolution.Methods: We collected 91 patients with DTC, 73 wom...

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...

Introduction and objectives: The strategies for therapy of metastatic medullary thyroid carcinoma (MTC) are limited. Although Tyrosine kinase inhibitors (TKI) seem to be the first-line treatment, we want to explore other possibilities. Metaiodobenzylguanidine (MIBG) is a guanethidine derivative, structurally similar to norepinephrine. It was developed as an imaging agent with 123I radiolabeling. MIBG localizes neuroendocrine tumors including MTC. We are investigatin...

Introduction: Even Though resection via transsphenoidal surgery is the optimal primary treatment for growth hormone (GH) secreting pituitary adenomas, medical therapy must also be considered when biochemical control after surgery is not achieved. The aim of our study was to describe the cure rates of acromegaly patients after different lines of therapy.Methods: A retrospective study (1971–2022) of 89 patients diagnosed with acromegaly was conducted....

The role of adjuvant external beam radiotherapy (EBRT) in differenciated thyroid cancer (DTC) is controversial. It remains unknown whether EBRT in the neck following conventional treatment might improve progression-free survival (PFS) and overall survival (OS).Objective: To assess EBRT outcomes in patients with locally advanced DTC in terms of local disease progression, PFS and OS.Material and Methods: A multicentric retrospective ...
