Differentiated thyroid cancer is rare in children and adolescents. An aggressive clinical presentation, together with a high rate of recurrences contrasting with low mortality, has been reported, especially, before the age of 15 years. Data are mainly issued from historical series from hospital databases.The aim of the study was to analyze, from a population-based registry, the clinical presentation and outcome of differentiated thyroid cancer in young s...

Background/objective: mETE has shown no effect on survival, and the 8th edition of the AJCC classification no longer considers mETE in the pT3 definition. Therefore, tumors with mETE below 40 mm are now staged pT1/pT2. However, controversy remains regarding mETE impact on disease recurrence. This study assessed the risk of recurrence of PTC patients previously classified as pT3 because of mETE, compared to PTC patients staged pT1-pT2.Methods: Monocentric...

Bone radioiodine (RAI) uptake without structural abnormality in thyroid cancer (TC) patients may be related to false positive or to microscopic foci of metastatic tissue. In such cases, outcome is reported to be excellent. Mrs D. had been operated for a pT3(m) poorly differentiated TC at the age of 43. The first post-therapeutic whole body scan revealed 3 foci of bone uptake (right clavicle, L2, L3). The elevated level of thyroglobulin (157 ng/mL) favoured the hypothesis of bo...
