Abstract

It is critical to identify biomarkers and functional networks associated with aggressive thyroid cancer to anticipate diseaseprogression and facilitate personalized patient management. We performed miRNome sequencing of 46 thyroid tumorsenriched with advanced disease patients with a median follow-up of 96 months. MiRNome profiles correlated with tumor-specific histopathological and molecular features, such as stromal cell infiltration and tumor driver mutation. Differentialexpression analysis revealed a consistent hsa-miR-139-5p downexpression in primary carcinomas from patients withrecurrent/metastatic disease compared to disease-free patients, sustained in paired local metastases and validated in publicly
