The vertiginous expansion of knowledge about endocrinology brings some caveats to the clinical practice. For instance, differentiated thyroid cancer, which was a relatively uncommon neoplasia 40 years ago(1) , has been increasing more than any other type of cancer in the last decade(2) . In fact, it became the most common neoplasia in women of certain countries(3) . However, despite this impressive increase in incidence, differentiated thyroid cancer mortality rates remain like 40 years ago(1) . This article is protected by copyright...

Differentiated thyroid cancer (DTC) is the most common malignancy of the endocrine system. There has been a significant increase in its incidence over the past two decades attributable mainly to the use of more sensitive diagnostic modalities. Ultrasound-guided fine needle aspiration cytology is the mainstay of diagnosis of benign disorders and malignancy. However, approximately 20% of lesions cannot be adequately categorized as benign or malignant. In the post-operative setting, monitoring of thyroglobulin (Tg) levels has been employed for the detection of disease recurrence...

BACKGROUND: Serotonin secretion occurs in approximately 1-4% of patients with a pancreatic neuroendocrine tumour (PNET), but the incidence is not well defined. The aim of this study is to determine the incidence of serotonin secretion with and without carcinoid syndrome, and the prognostic value for overall survival (OS). METHODS: Data were collected from 255 patients with a PNET if 24-hour urinary 5-hydroxyindoleacitic acid excretion (5-HIAA) was assessed. Patients were diagnosed with serotonin secretion if 24-hour urinary 5-HIAA excretion was more than 3x the upper limit of normal (ULN) of 50 μmol/24 hours during follow-up...
