Introduction: The 2015 American Thyroid Association (ATA) guidelines on the management of thyroid nodules and cancer recommend specific size cut-offs for fine needle aspiration (FNA) cytology. We assessed the correlation between sonographic and cytological stratification as per the guidelines, with emphasis on the size cut-offs.Methods: In a ‘real world’ prospective study, we sonographically stratified 562 thyroid nodules prior to performing ul...

Background: At a preplanned interim analysis (median follow-up 6.2 months) of the double-blind, phase 3 COSMIC-311 trial (NCT03690388), cabozantinib significantly improved progression-free survival (PFS) vs placebo (HR 0.22, 96% CI 0.13-0.36; P<0.0001) in 187 patients with previously treated radioiodine-refractory DTC (Brose, Lancet Oncol; 2021). Patients must have received lenvatinib or sorafenib and progressed during or after 1-2 prior VEGFR inhibitors. We prese...

Background: The appropriate risk stratification of patients with differentiated thyroid cancer (DTC) is crucial because most cases have an indolent behavior and need a conservative approach. One of the most widely used tools is included in the American Thyroid Association (ATA) Guidelines, based on heterogeneous literature data derived by different populations, settings, and timeframes. Recent research focused on the inclusion of other features or questioned the clinical relev...

Background: Increasing age is associated with poorer survival in DTC [Oyer SL, 2012]. In the phase 3 COSMIC-311 trial (NCT03690388), cabozantinib, an inhibitor of VEGFR2, MET, AXL and RET, significantly improved the progression-free survival (PFS) vs placebo in previously treated patients with RAI-R DTC (HR 0.22, 96% CI 0.13-0.36; P<0.0001; median follow-up 6.2 months). The impact of age on efficacy and safety was included in the prespecified subgroup analysis.</p...

Background: MiRNAs transported by exosomes play a role in various processes of tumorigenesis and tumor progression. They can function as oncogenes able to structurally and biologically change the tumor microenvironment (TME) therefore playing a crucial role in cell-to-cell communication during tumor development and allowing cancer cells to become invasive and disseminate from the primary site to distant locations.We aimed to identify the exosome miRNAs that may be involved in ...

Objective: RET fusion genes are known driver mutation in thyroid cancer and have been described mainly in pediatric thyroid carcinomas, in which they represent the most common genetic alteration. In large cohorts of adult patients, RET fusions have not yet been well characterized. The aims of this study were to identify RET fusion-positive thyroid tumors in a cohort of different types of thyroid carcinomas and to correlate them with clinical and hist...
