Aim: Investigate, in patients with differentiated thyroid cancer (DTC) if thyroglobulin (Tg) values, immediately before and six months post radioiodine ablation are good predictors of disease progression.Materials and methods: Basal Tg values (Tg-B) and rhTSH stimulated Tg (Tg-S) before ablation (0) and 6 months later (6) from 142 DTC patients, with post-surgical ablation therapy between 2003 and 2009 with a follow up of 5 years, were analysed.<p cla...

In PTC, radioiodine required dose for thyroid remnant ablation is uncertain. Recent works show that low doses may be sufficient for low risk patients.Aim: To evaluate the efficacy and safety of thyroid remnant ablation in patients with low-risk PTC by using 1100 MBq (30 mCi) outpatient doses.Materials and methods: Twenty-five patients (24 women, 55 years-old mean age, range 34–77) referred for ablation of postsurgical thyroid ...

Introduction: Incidental focal uptake in the thyroid gland is detected in 1%–2% of 18FDG-PET examinations. FNA is recommended due to an increased risk of malignancy (25–50%), but these figures are extracted from the studied cases (about a half). Moreover there is controversy about the maximum standardized uptake value (Suvmax) ability to discriminate between benign or malignant nodules.Methods: We retrospectively reviewed 4207 FDG-PE...

Introduction: The relationship between the BRAF gene mutation in papillary thyroid cancer (PTC) and the presence of lymph node metastasis (LNM) is a subject of controversy.Objective: To analyse the influence of BRAF mutation status in the characteristics of lymph nodes in patients with PTC submitted to lymph node dissection (LND).Material and methods: Lymph nodes obtained from 20 patients (12 females, mean age 50±15 y...
