CONTEXT Radioactive iodine is a crucial tool for treatment of differentiated thyroid cancer (DTC). In 5% of cases, DTCs lose I-131 avidity and assume an aggressive behaviour. Treatment options for iodine-refractory DTC are limited. We report the experience of off-label use of the tyrosine kinase inhibitor sorafenib for treatment of advanced(More)
CONTEXT BRAF(V600E) is considered a negative prognostic marker in papillary thyroid carcinoma (PTC), but unexplained conflicting results are present in the literature. In light of the new finding that most PTC consist of a mixture of tumor cells with wild-type and mutant BRAF, we examined the associations between the percentage of BRAF(V600E) alleles and(More)
BACKGROUND Fine-needle aspiration biopsy (FNAB) is the primary means to distinguish benign from malignant nodules and select patients for surgery. However, adjunctive diagnostic tests are needed because in 20-40% of cases the FNAB result is uncertain. OBJECTIVE We investigated whether a search for the oncogenes RET/PTC, TRK and BRAF(V600E) in thyroid(More)
Liver metastases from neuroendocrine tumor (NET) can be treated by transarterial embolization (TAE) or transarterial chemoembolization (TACE). The goal of TAE and TACE is to reduce blood flow to the tumor resulting in tumor ischemia and necrosis. In this retrospective study, the effectiveness and safety of TAE-TACE in the treatment of liver metastases in(More)
Fine-needle aspiration cytology (FNAC) is the primary means to distinguish benign thyroid nodules from malignant ones. About 20% of FNAC yields indeterminate results leading to unnecessary or delayed surgery. Many studies of tissue samples, the majority of which are retrospective advocate testing for RET rearrangements as a diagnostic adjunctive tool in(More)
BACKGROUND Concomitant papillary thyroid cancer (PTC) and Hashimoto's thyroiditis (HT) is a frequent occurrence. Whether these two conditions are linked and whether PTC with concurrent HT has distinct clinicopathological characteristics are still debated issues. Lymphocytic infiltration is abundant in HT and might be relevant in the pathogenesis and(More)
PURPOSE Percutaneous radiofrequency thermal ablation (RTA) was reported as an effective tool for the management of thyroid nodules (TNs). The aim of this study was to investigate the effects of RTA and to establish whether they were treatment-related by comparison with a matched, untreated control group. PATIENTS AND METHODS The study population included(More)
Vascular injuries resulting from blunt trauma are uncommon in the pediatric age. In children, there are particular factors that should be taken into account when vascular traumatic lesions are treated: small vessel size or vessel spasm, a higher risk of infection, a tendency for restenosis, and rapid body growth. The endovascular procedure is a minimally(More)
Liver metastases occur in 46-93% of patients with neuroendocrine neoplasms (NENs). Presence and extension of liver metastases are considered important prognostic factors, as they may significantly impair the patient's quality of life, because of either tumor bulk or hormonal hypersecretion. Therapies for NEN liver metastases include surgical resection,(More)
