Brief Summary:
This project is a retrospective observational study based on the molecular characterization of a Spanish population of patients with refractory radio-iodine differentiated thyroid cancer (DTC) and medullary thyroid carcinoma (MTC) with advanced and / or metastatic disease undergoing systemic treatment, or under clinical observation.
Three diagnostic techniques will be performed on formalin-fixed paraffin embedded (FFPE) tumor samples from the study population: immunohistochemistry (IHC), fluorescence by in situ hybridization (FISH) as well as Next-Generation Sequencing (NGS) techniques by means of DNA and RNA analysis (Ion Platform Torrent - Oncomine Focus Assay, 52 gene detection). The results of each patient will be compared in order to correlate the results of each method.

The results of each patient will be compared in order to correlate the results of each method.
Detailed Description:
Immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) techniques will be carried out to identify NTRK and RET alterations. NTRK alterations will be identified using IHC techniques (NTRK over-expression), and FISH techniques (break-apart method). RET alterations will also be identified using the FISH technique (break-apart method).
At the same time, DNA and RNA will be extracted for sequencing techniques using the Oncomine Focus Assay platform, including 52 genes (35 Hotspot genes, 19 Copy number variants and 23 Gene fusions, including NTRK and RET).
