Objective: Clarify mechanisms determining thyroid homeostasis during pregnancy at hypothalamic-pituitary level.Methods: Retrospective analysis of 251 pregnant women. 220/251 euthyroid without thyroxine therapy (Group 1), 31/251 thyroidectomized under thyroxine replacement therapy (Group 2). Patients under thyroxine replacement therapy with a TSH between 0.4 and 4.0 were included in the study. Patients with combined T3/T4 therapy were excluded.<p clas...

Background: The 2022 WHO Classification of Endocrine and Neuroendocrine Tumors has introduced, as other neuroendocrine neoplasms, new pathological features to classify medullary thyroid carcinoma (MTC) in low/high grade. However, whether it can be reliable in clinical practice should be confirm by further studies.Aim: To verify the predictive value of the 2022 WHO grading system in patients with MTC.Materials and Methods: Tumor tis...

Background: Tyrosine kinase inhibitors (TKIs) are modern antineoplastic molecules widely used in the medical treatment of many cancers including iodine refractory differentiated thyroid carcer (DTC) and advanced medullary thyroid cancer (MTC). In patients with thyroid gland, TKIs frequently cause a destructive and/or autoimmune thyroiditis with consequent hypothyroidism. However, authors have reported unexpected TSH increase or hypothyroidism even in patients with total thyroi...
