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...

ObjectivesRearrangement involving one of the neurotrophic-tropomyosin receptor kinase (NTRK) genes belonging to the NTRK family represents a significant oncogenic event in thyroid cancer (TC). Recently, there has been a growing interest in testing and characterizing NTRK fusion genes because they are therapeutically targetable. This study aimed to determine a frequency, clinical and histopathological features of a large cohort ...

Objectives: RET fusion genes are known driver mutations in papillary thyroid carcinomas (PTCs) and have been described mainly in pediatric PTCs, in which they represent the most common genetic alteration. The aims of this study were to identify RET fusion genes in PTCs (from pediatric as well as adult patients), to correlate them with clinical and histopathological features and to determine the prognostic significance of RET fusion genes based on lon...

Objectives: Variants in the EIF1AX gene have been reported in malignant as well as benign thyroid nodules and their clinical significance is still unclear due to their low prevalence. The aim of this study was to identify EIF1AX variants in a large cohort of different types of thyroid nodules and to correlate them with clinical and pathological data.Methods: The study consisted of 904 thyroid nodule samples. The cohort included 577 papi...
