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)
Scopolamine in acute intramuscular doses of 0.25-0.75 mg reduced the P2-N3 flash-VEP amplitude and, in the quantitative EEG, the 8.5-12.0 Hz power and total power in 8 healthy young male volunteers. The effects on flash-VEP and EEG total power were dose dependent and were evident 30 min and 90 min respectively after drug administration, regardless of dose.(More)
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)
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)
CONTEXT Usefulness of circulating Chromogranin A (CgA) for the diagnosis of neuroendocrine tumors (NEN) is controversial. The aim of the present study was to assess the actual role of this marker as diagnostic tool. METHODS Serum blood samples were obtained from 42 subjects affected with NEN, 120 subjects affected with non-endocrine neoplasias (non-NEN)(More)
Thyroid diseases are the commonest endocrine disorders in the general population. In most of the cases, they are consistent with benign conditions which may be asymptomatic or affect people at a variable extent. Since they often represent chronic conditions their prevalence increases by age and reaches in elderly the highest rates. Thyroid nodules are a(More)
Cytological examination of fine needle aspiration biopsy is the primary means for distinguishing benign from malignant nodules. However, as inconclusive cytology is very frequent, the introduction of molecular markers in the preoperative diagnosis of thyroid nodules has been proposed in recent years. In this article, we review the clinical implications of(More)
CONTEXT BRAF(V600E) is considered a primary event, a negative prognostic marker, and a site for pharmacological intervention in papillary thyroid carcinoma (PTC). We asked whether BRAF(V600E) can occur as a subclonal event in PTC and whether this and other oncogenes can coexist in the same tumor. STUDY DESIGN We determined by pyrosequencing the percentage(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)
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)
