Malignancy risk stratification in thyroid nodules according to the Bethesda system for reporting thyroid cytopathology

Kowalska Aldona , Suligowska Agnieszka , Kopczynski Janusz , Niemyska Kornelia , Gozdz Stanislaw

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...

The presence of BRAFV600E mutation in patients diagnosed of papillary thyroid carcinoma in holycross cancer centre in Kielce, Poland

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...

Does the delayed risk stratification system help to evaluate the risk of unfavorable clinical outcome in pT1aN0/Nx stage patients with differentiated thyroid cancer treated without radioactive iodine?

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...

Impact of different methods on the detection frequency of BRAF mutation in papillary thyroid carcinoma

Kowalik Artur , Kowalska Aldona , Kopczynski Janusz , Walczyk Agnieszka , Nowak Ewelina , Wypiorkiewicz Elzbieta , Chodurska Renata , Pieciak Liliana , Gozdz Stanislaw

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...

Occurrence other than V600E mutation in the BRAF gene in papillary thyroid carcinoma

Kowalik Artur , Kowalska Aldona , Kopczynski Janusz , Walczyk Agnieszka , Nowak Ewelina , Wypiorkiewicz Elzbieta , Chodurska Renata , Pieciak Liliana , Gozdz Stanislaw

Introduction: BRAFV600E mutation constitutes 98–99% of all detected mutation in thyroid carcinoma. The remaining 2% are BRAF mutations detected in the vicinity of codon V600. Due to the low incidence not much is known about their importance for the development of papillary thyroid carcinoma (PTC). In addition, some of these mutations co-occur with the mutation BRAFV600E.Methods/design: The study prese...

High sensitivity of BRAF detection method does not alter response to therapy of papillary thyroid cancer of known BRAF status

Walczyk Agnieszka , Kowalska Aldona , Kowalik Artur , Kopczynski Janusz , Palyga Iwona , Gasior-Perczak Danuta , Mikina Estera , Lizis-Kolus Katarzyna , Szyska-Skrobot Dorota , Szymonek Monika , Hurej Stefan , Kajor Maciej , Chrapek Magdalena , Gozdz Stanislaw

Background: 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). The analysis of BRAF status is not routinely recommended by ATA, although this finding may be advantageous to individualized risk-adapted approach in papillary thyroid cancer (PTC). The methods used to detect the BRAF V600E are known of variation...

The usefulness of determining the presence of BRAF (V600E) mutation in fine needle aspiration cytology of thyroid nodules cells

Kowalska Aldona , Kopczynski Janusz , Kowalik Artur , Gasior-Perczak Danuta , Palyga Iwona , Lizis-Kolus Katarzyna , Waligorski Dariusz , Szyska-Skrobot Dorta , Walczyk Agnieszka , Hurej Stefan , Chil Agnieszka , Chodurska Renata , Chlopek Malgorzata , Wypiorkiewicz Elzbieta , Nowak Ewelina , Gozdz Stanislaw

Introduction: Fine needle aspiration cytology (FNACC) is the basic tool used in the diagnosis of thyroid cancer (TC) in nodular goitre. FNACC does not allow for the establishment of a clear diagnosis in 15–30% of cases (mainly follicular lesions). Molecular biology techniques can be useful, allowing for the detection, in FNACC smears, of the known mutations involved in the oncogenesis.Aim: To evaluate the usefulness of the detection of the BRAF muta...

Does body mass index influence the clinical stage, treatment response and course of the disease in patients with differentiated thyroid cancer?

Introduction: Obesity is a serious health problem worldwide, especially in well developed countries. It is a cause of various diseases, including thyroid cancer. The relationship between obesity and prognostic factors of thyroid cancer is uncertain.Aim of the study: Evaluation of relationship between the body mass index (BMI) and clinicopathological features increasing the risk of poor clinical course, treatment response and clinical outcome in patients ...
