Introduction: Fine needle aspiration biopsy (FNAB) plays a crucial role in the diagnosis of thyroid nodules. The choice of further therapeutic strategy depends largely on its result. Knowledge of the risk of malignancy in each diagnosis class in the population is necessary. The aim of the research was to analyse the risk of malignancy in thyroid nodules in each diagnosis class according to Bethesda system.Materials and methods: Retrospective research inc...

Background: The activating somatic point mutation, BRAFV600E, is the most common genetic alteration observed in papillary thyroid carcinoma (PTC) but its oncogenic role in PTC has been extensively investigated. Numerous studies reported that BRAFV600E correlates with poor clinical outcome, whereas others have found no such association. It is estimated that BRAFV600E occurs in ~ 45–50% of PTC cases, but recent studies showed the more freque...

Introduction: The correct 25-hydroxy vitamin D (25(OH)D) level plays a key role in the proper supply of vitamin D for the organism. Vitamin D deficiency may lead to an increased risk of development of various neoplasms, including papillary thyroid carcinoma (PTC).Aim: Evaluation of the prevalence of vitamin D deficiency in patients with PTC and analysis of the relation between 25(OH)D levels and age, sex, place of living, severity of the disease, and pre...

The pentagastrin-stimulated calcitonin test is known and widely used in monitoring patients with MTC. Given the problems of pentagastrin availability other diagnostic tests are being tried.The goal of the study was the evaluation of safety and tolerance of high-dose calcium to stimulate calcitonin in MTC patients.Materials: The study included 41 patients after surgery for medullary thyroid cancer who were under observation. Patient...

Introduction: The Pg calcitonin stimulation test is widely used in monitoring patients with MTC. In view of accessibility problems of Pg it is necessary to use high doses of calcium as the calcitonin stimulant.Objective: The aim of the study was the comparison of calcitonin concentrations after Pg and calcium stimulation, respectively.Materials: The study was performed in 31 patients under observation after deemed surgically cured ...

Introduction: Calcitonin is the main MTC marker. However, it has limitations: rapid in vitro degradation, a concentration-dependent biphasic half-life, presence of different isoforms and high cost of a single trial. Other markers of MTC can be procalcitonin and ProGRP.Aim: The aim of the study was to evaluate the diagnostic performance of marking the levels of procalcitonin and ProGRP in monitoring patients with MTC.Material...

Introduction: Case reports of individuals with non-insulinoma hyperinsulinic hypoglcaemia of organic origin has been more frequently described in literature. This syndrome has been described as a rare complication of bariatric surgeries and the term of NIPHS (non-insulinoma pancreatogenic hypoglycemia syndrome) has been proposed.Aim: The aim of our study is to present patients case who had previously undergone the gastric surgery. Bilroth II and finally ...

Introduction: In ATA recommendations (2016) a delayed risk stratification (DRS) system proposed by D.P. Momesso et al. was accepted as a diagnostic tool for the risk stratification of unfavorable clinical outcome and for monitoring the clinical outcome in differentiated thyroid cancer (DTC) patients treated without radioactive iodine (RAI).The aim of the study: To evaluate the DRS system in patients with low clinical stage (pT1aN0/Nx).<p class="abste...

Introduction: The activating BRAFV600E is the most common genetic alteration in PTC. There is a common belief that it can correlate with a more aggressive clinical course. The mutation of the CHEK2 gene impairs the repair processes of the damaged DNA. It can be expected that the coexistence of both mutations can be related to a worse clinical course.Aim: To assess the prevalence of the coexistence of the CHEK2 and BRAFV600E mutation...

Introduction: Still there is a discussion about the importance of diagnostic and prognostic relevance BRAFV600E mutation. The wide range of BRAFV600E mutation frequency (40–80%) doesn’t facilitate this task. Population diversity and genotyping methodology are suspected sources of differences seen in the mutation frequencies detected by different studies. The aim of this study was to assess the prevalence BRAF V600...
