RET fusion genes in pediatric and adult thyroid carcinomas: cohort characteristics and prognosis.

Thyroid cancer is associated with a broad range of different mutations, including RET (rearranged during transfection) fusion genes. The importance of characterizing RET fusion-positive tumors has recently increased due to the possibility of targeted treatment. The aim of this study was to identify RET fusion-positive thyroid tumors, correlate them with clinicopathological features, compare them with other mutated carcinomas, and evaluate long-term follow-up of patients.

Fusion Genes in Thyroid Carcinomas: Clinicopathological Characteristics and Their Impacts on Prognosis.

Chromosomal rearrangements of genes are oncogenic driver mutations in thyroid cancer (TC). This study aimed to identify fusion-positive thyroid tumors and to correlate them with clinical and pathological data and determine their prognostic significance. The cohort consisted of 989 different TC samples.

Morbidity and mortality associated with thyroid surgery - retrospective analysis 19912010.

Introduction: The incidence of thyroid disorders has been rising worldwide. Unlike the incidence, mortality associated with malignant thyroid cancer shows only a modest increase. Between 1979 and 2009, mortality in Czech women increased from 1.

Thyroid tumors at the limit of operability.

Comprehensive information about current thyroid carcinoma treatment options depending on its histology and extent of the disease, focusing on locally advanced findings at the limit of operability. Treatment of such a heterogeneous group requires interdisciplinary cooperation. We provide 6 unique case reports including imaging scans, description of the therapy and description of development of the condition.

Polymorphisms in selected DNA repair genes and cell cycle regulating genes involved in the risk of papillary thyroid carcinoma.

Background: Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. In addition to causal somatic mutations in the BRAF gene and RET/PTC rearrangements, the contribution of single nucleotide polymorphisms (SNPs) in low-penetrance genes in the development of PTC has been proposed.

Methods: Four SNPs in the XRCC1 (Arg399Gln, Arg280His, Arg194Trp and T-77C) and one SNP from each of three other genes participating in DNA repair pathways and/or cell cycle regulation (ATM Asp1853Asn, TP53 Arg72Pro, CDKN1B Val109Gly) were selected.
