Use of recombinant human thyroid-stimulating hormone (rhTSH) in children and adolescents with differentiated thyroid cancer

Mackova Marketa , Sykorova Pavla , Vlcek Petr

Paediatric thyroid cancer is rare but belongs to the most frequent malignancies in children and its incidence increases. The difference from adult disease subsists in good curability despite of quicker proliferation and earlier development of metastases. Influence of previous radioactivity exposure in the pathogenesis has been proven.For the optimal uptake of radioiodine 131I in the post-operative thyroid remnants itÂ’s necessary to achiev...

Conditions and implications of rhTSH application for ablation in treatment of Differentiated thyroid cancer

Sykorova Pavla , Mackova Marketa , Vlcek Petr

A basic tool of the thyroidal cancer treatment is the total thyroidectomy. Immediately after the thyroidectomy, the patients receive a thyroxin. In the case of positive histology after lobectomy, we first indicate the total thyroidectomy. If the tumor is larger than 1 cm or if is a multifocal one, we indicate the ablation of the remnant with I131.Usually, the differentiated thyroid cancer is non-aggressive and we proceed with a standard way of...

Scintigraphy 131I-mIBG in patient with positive ret germline mutation for medullary thyroid carcinoma

Vlcek Petr , Zimak Jaroslav , Sykorova Pavla

Purpose: Familial medullary thyroid carcinoma (FMTC) is an autosomal dominant inherited disease, characterized by germ-line mutations in the RET proto-oncogene, mainly in exons 10 and 11, but also in exons 13, 14 and 15. Activating germ-line mutations in the RET proto-oncogene cause the development of familial medullary thyroid carcinoma (FMTC) or medullary thyroid carcinoma (MTC) as a part of multiple endocrine neoplasia type 2 syndrome (MEN2).Me...

Objectives: Although, almost all patients with inherited medullary thyroid carcinomas (MTC) harboured RET proto-oncogene mutation, in patients with sporadic MTC, mutations in RET are detected only in half of cases. Thus still unknown genetic causes are responsible for half of sporadic MTC and it is necessary to search for another mutations.Methods: DNAs from fresh frozen thyroid tissues of 27 sporadic MTC were extracted. The next-genera...

Pediatric thyroid cancer is associated with more aggressive phenotype and more frequent RET/PTC rearrangements compared with the adult patients

Thyroid cancer in children and adolescents is a rare disease but with an increasing incidence. As in adults, the most prevalent type is papillary thyroid carcinoma (PTC). Our aim was to describe the clinical and genetic comparison between pediatric and adult PTC. We analyzed the cohorts of 73 pediatric PTC (5-18 years, female to male ratio 2.3:1, 10 patients <10 years) and 460 adult PTC patients. DNA and RNA were extracted from cancer tissue samples. DNA was used for seque...

Objectives: The identification of novel causing genes in thyroid carcinoma is very important in diagnosis and prognosis of the disease. Recently, The Cancer Genome Atlas (TCGA) study found EIF1AX, CHEK2 and PPM1D genes as new minor causing genes in the papillary thyroid cancer (PTC) development. The goal of this study was to detect variants in these genes in PTC, follicular thyroid carcinoma (FTC) and anaplastic thyroid carcinoma (ATC) cohorts.<p class="a...
