Opis:
Iodine is an essential element for the production of thyroid hormones. In recent years, it has been suggested that excessive consumption of iodine may play a role in the pathogenesis of papillary thyroid cancer (PTC). In addition, studies have suggested that high iodine consumption is an important risk factor for the formation of a BRAF mutation in the thyroid gland. A prospectively designed study included 132 cases scheduled for thyroidectomy for various reasons. Urine iodine levels of all patients were examined before the operation. The iodine excretion levels of the patients were grouped according to the median urinary iodine concentration determined in community screenings (those with <100 µg L-1 low iodine excretion, those with 100-199 µg L-1 normal iodine excretion, those with 200-299 µg L-1 high iodine excretion). Patients were divided into 3 groups according to the post-operative pathology results. As a result of thyroid histopathology, benign (n: 44), PTC (n: 88) (BRAF (+): 44 and BRAF (-): 44) cases were included in the study. BRAF mutations in patients diagnosed with PTC were evaluated using the “Real Time PCR Melting Curve Analyzer” method. The relationship between urinary iodine excretion levels and clinical, histopathological and BRAF positivity was examined. In our study, no difference was found in urinary iodine excretion between patients with and without PTC. Hashimoto’s thyroiditis was observed more frequently in patients with PTC (p=0.023). In addition, Hashimoto’s thyroiditis was statistically more frequently detected in the BRAF (-) group compared to the BRAF (+) and control group (p=0.034). Despite studies suggesting that high iodine consumption is important in PTC pathogenesis, we did not find a relationship between the mutation and iodine consumption, which plays an important role in the development of PTC.

Opis:
Overdiagnosis of thyroid cancers contributes to increased incidence of thyroid cancers worldwide, which is already a serious public health problem. A great number of medical tests, helping to detect thyroid cancer, may result in an epidemic of diagnosis. A dramatic increase in the number of detected cases of thyroid cancer may be associated with a great number of neck ultrasounds, fine- needle aspirations and incidental findings during examination. Unfortunately, in response to overdiagnosis, more and more surgeries are being performed. It is important to differentiate stationary cancers from potentially aggressive diseases. Detection of cancer contributes to saving lives. However, in some instances it can be harmful, particularly if the disease is overdiagnosed. The aim of this review is to give a balanced view of thyroid cancer epidemic and controversies arising out of overdiagnosis.

Opis:
Fine needle aspiration cytology (FNAC) is considered as the gold-standard diagnostic test in the diagnostics of thyroid nodules. It is a cost-effective procedure that provides specific diagnosis rapidly with minimal complications. It plays an important role in the determination of treatment - patients with suspected malignancy diagnosis can be subjected to surgery. On the other hand, it can decrease the rate of unnecessary surgeries. Aim: The aim of this study was to evaluate and compare the correlation, accuracy of fine needle aspiration cytology (FNAC) in the diagnostics of thyroid lesions with the final histopathologic diagnosis based on the surgical specimens. Materials and Methods: In our study we performed a retrospective analysis of a case series of patients who had been admitted to the Department of Endocrine, General and Oncological Surgery of the Hospital of M. Kopernik in Łodź (Poland) between May 2016 and December 2017 and underwent FNAC with subsequent surgery. Cytological diagnosis was classified into six Bethesda categories. Results: On cytological examination, 1070/1262 cases were reported as benign, 49 as malignant and 143 as suspicious. On histopathological examination, 956/1070 cases were confirmed as benign but there were 114 discordant cases. Among the other cases histopathology diagnosis confirmed malignancy in 45/49 cases and 128/143 suspicious cases. The sensitivity and specificity were 60,28% and 98,05% respectively. False positive rate was 1.95% and false negative rate was 39.72%. The positive predictive value was 90.1% and negative predictive value was 89.35%. Accuracy of FNA in differentiating benign from malignant thyroid lesions was 89.46%.

Opis:
Objectives Investigate the impact of daily occupational walking steps on the progression of papillary thyroid cancer (PTC), a topic hitherto underresearched. Material and Methods The authors analyzed the data from 800 individuals with PTC across stages 0–IV. Participants were evenly divided into 2 distinct occupational groups: office workers and construction workers (N = 400 each). Data included comprehensive records of daily walking steps, demographic information, and clinical indicators. Pearson’s correlation coefficients or analysis of variance (ANOVA) were employed to assess the linkage between daily walking steps and PTC risk and stage, as well as associated biochemical markers. Results The analysis revealed a significant inverse relationship between daily walking steps and PTC risk. A higher frequency of daily steps was associated with reduced chances of PTC onset and a lower diagnostic stage of the disease. This protective effect of physical activity was particularly pronounced in the construction worker cohort. Subsequent evaluations showed that construction workers who consistently logged higher daily steps had markedly lower levels of thyroid-stimulating hormone (TSH), free triiodothyronine, free thyroxine, thyroid peroxidase antibody, thyroglobulin antibody, and thyroglobulin (Tg). Notably, daily walking steps exhibited a strong inverse correlation with body mass index (BMI), age, PTC volumes, and levels of TSH and Tg across both occupational groups (ρ < –0.37). The increase in daily steps was associated with the reduction in PTC stages (p < 0.001). Conclusions The research underscores the potential benefits of increased daily walking steps, suggesting that they may play a protective role in reducing PTC risk and moderating its progression.
