INTRODUCTION Calcitonin is a very sensitive marker of medullary thyroid carcinoma (MTC). High concentrations of basal or pentagastrin stimulated calcitonin in patients with MTC is a signal of recurrence or metastatic disease. Detection of metastatic foci remains a diagnostic and therapeutic challenge. The aim of the study was to present examples of the use(More)
Mutations in the cell cycle checkpoint kinase 2 (CHEK2) tumor suppressor gene are associated with multi-organ cancer susceptibility including cancers of the breast and prostate. A genetic association between thyroid and breast cancer has been suggested, however little is known about the determinants of this association. To characterize the association of(More)
UNLABELLED BACKGROUND The so called "big-big" prolactin (Prl), also known as macroprolactin is formed by Prl-immunoglobulin (Prl-IgG) complexes and may cause elevation of serum Prl concentrations measured by standard assays, potentially leading to unnecessary investigations and/or treatment. In our study, we have endeavoured to assess the prevalence of(More)
BACKGROUND The treatment of differentiated thyroid cancer (DTC) ends in full recovery in 80% of cases. However, in 20% of cases local recurrences or distant metastases are observed, for this reason DTC patients are under life-long follow-up. The most sensitive marker for recurrence is stimulated thyroglobulin (Tg) which, together with neck ultrasound (US),(More)
CONTEXT There has been a marked increase in the detection of differentiated thyroid carcinoma (DTC) over the past few years, which has improved the prognosis. However, it is necessary to adjust treatment and monitoring strategies relative to the risk of an unfavourable disease course. MATERIALS AND METHODS This retrospective study examined data from 916(More)
INTRODUCTION Fine-needle aspiration biopsy (FNAB) is regarded as the gold standard method for the diagnosis of thyroid nodules, but it has its limitations. Additional methods that would improve sensitivity and specificity in the diagnosis of thyroid cancer (TC), especially in indeterminate lesions. Molecular tests seem to be such a tool. BRAF V600E mutation(More)
OBJECTIVE A dynamic risk stratification with modified initial estimated risk based on response to therapy and disease course is one of the crucial changes adopted recently by the American Thyroid Association (ATA). This approach focuses on an individualized risk-adapted approach to the management of differentiated thyroid cancer. The BRAF V600E mutation is(More)
INTRODUCTION Monitoring of patients with differentiated thyroid carcinoma consists of a periodic control for thyroglobulin (Tg) concentration and radioiodine diagnostics during stimulation of endogenous TSH. Application of recombinant TSH is an alternative procedure which considerably increases cost of diagnostics but allows to avoid symptoms of(More)
OBJECTIVES The aim of the study was to compare the calcitonin (CT) stimulation tests with tests of calcium gluconate (CaG) and pentagastrin (PG), their tolerance and usefulness of PCT in the patients' diagnosis with active Medullary thyroid cancer (MCT) after thyroidectomy. METHODS CT was marked in serum by the immunosorbent sandwich test. PCT was marked(More)
