Background: Patients with type 2 diabetes (T2DM) are generally known to have increased risk of various types of cancer. However, the studies addressing the association between T2DM and thyroid cancer are heterogeneous and inconclusive. The aim of our study was to evaluate the patients who have already undergone thyroid surgery with histologically confirmed results as the ‘gold standard’.Methods: A retrospective study in 102 patients (74 women a...

Objectives: Pathogenic variants in the DICER1 gene can be found in both benign and malignant thyroid nodules, more often in pediatric patients. Somatic pathogenic variants in "hotspot" regions can coexist with germline variants in other regions of the DICER1 gene, which are associated with DICER1 syndrome, an autosomal dominantly inherited disease that predisposes to the development of various tumors from childhood. In addition to thyroid tumors, pleu...

Objectives: Effective patient management is about finding a balance between overtreatment and undertreatment. Finding the border is very difficult due to the hardly predictable development of carcinoma. Molecular markers and their testing could help distinguish between low-grade and high- grade carcinomas. One of these molecular markers is a BRAF fusion gene. The aim of this study was to identify BRAF fusion genes in thyroid carcinomas, to correlate them with...

Identification of rare braf variants in thyroid nodules

Objectives: The substitution BRAF p.V600E is the most common genetic cause of the papillary thyroid carcinoma (PTC) and represents more than 95% genetic variants in BRAF gene. Other rare variants in the BRAF gene include other substitutions (e.g. p.K601E), small deletions or insertions close to codon 600. The aim of this study was to analyze a large cohort of thyroid nodules for rare genetic variants in the BRAF gene.M...
