Background: Papillary thyroid cancer (PTC) is a disease with an indolent course, excellent overall prognosis and long-term survival. However, some PTCs are associated with an increased risk of recurrent disease and aggressive behaviour. Many exogenous factors, as obesity, could be implicated in the pathogenesis of thyroid cancer but the biological mechanisms that may explain this connection have been only partially described. Potentially factors that combine overweight with th...

Although 20% of follicular neoplasms are papillary thyroid carcinoma (PTC), their cytological diagnosis is not diagnostic. A different profile of gene expression between malignant and benign thyroid tumors has been reported. Aim of this study was to identify a gene expression profile to be used in distinguishing malignant from benign thyroid neoplasms. By real-time RT-PCR we analyzed mRNA expression of 6 thyroid differentiation genes (TTF-1, PAX8, TPO, TSHr, NIS and Tg) and 5 ...

BRAFV600E is the most common mutation in papillary thyroid carcinoma (PTC). Anatomo-patology and clinical features of PTC with BRAFV600E are well described in literature.Aim of this study was to examine the prognostic significance of BRAFV600E in patients with PTC and a follow-up of 15-20 years.Genomic DNA was purified from 67 paraffin-embedded tumoral tissue. A PCR-SSCP analysis of exon 15 of BRAF ...
