Background: The increase of papillary thyroid cancer (PTC) rate among children who were exposed to post-Chernobyl 131-I release was reported only four years after the accident, first in Belarus where the heaviest fallout happened. The evolution of the occurrence of thyroid carcinoma based on the age-period-cohort analysis and the effects of age, period, and birth cohort on time trends aimed to reveal if post-Chernobyl follicular cells irradiation still has been impacting on incidence rate of papillary thyroid carcinoma nowadays.
Methods: The Belarusian Cancer Registry was used to identify patients with PTC diagnosed during the years 1980-2019. The incidence trends were analysed using Join-point regression software.
Results: The highest peak of age-specific incidence curve was shown during the years 1980-2001 in the age group of 15-19 years old that was associated also with short-latency cases of post-Chernobyl PTC. This is the same age group that demonstrated significant growth of the incidence rate during the years 2006-2019, largely because of the increasing number of non-exposed patients with PTC (p < 0.001). Influence of post-Chernobyl exposure also can be seen in the young adults age-groups of patients (for 20-24 years old during the years 1980-2003 and 2013-2019, p < 0.001; for 25-29 years old during the years 1980-1999 and 1999-2011, p < 0.001).
Conclusion: After the Chernobyl accident, epidemiological waves that reflect the age shift of the group of children exposed to 131-I have consistently emerged. Currently, the incidence rate continues to increase only in the cohort of patients aged 20-44 years.

The incidence of thyroid cancer has shown marked increases globally over recent decades. This study investigated how the incidence of papillary thyroid carcinoma (PTC) subtypes and World Health Organisation (WHO) endocrine tumour classification changes have affected overall thyroid cancer incidence recorded in Australia. Using incidence data from the Australian Institute of Health and Welfare cancer registry (spanning 1982 to 2019), this descriptive epidemiological study employed joinpoint regression analysis to assess temporal trends in thyroid carcinoma incidence, focusing on PTC.

The longest reported follow-up for thermal ablation of papillary thyroid microcarcinoma (PTMC) is 5 years. We evaluated the long-term efficacy and safety of radiofrequency ablation (RFA) in patients with low-risk PTMC with clinical follow-up of more than 10 years. In this retrospective cohort study, we included patients with low-risk PTMC who had more than 10 years of follow-up after ultrasound (US)-guided RFA (performed between May 2008 and December 2013).

Summary: Oral levothyroxine (LT4) is prescribed worldwide for hypothyroidism. Bariatric surgery for patients with obesity has shown a substantial, long-term weight loss and considerable improvement of obesity-related diseases. LT4 malabsorption represents a significant cause of refractory hypothyroidism, well known after malabsorptive bariatric surgery such as Roux-en-Y gastric bypass.

Background: KI-67 (MKI-67 in humans) is a protein able to bind to DNA which contributes to cell growth and cell proliferation. KI-67 is currently considered as a biomarker that is widely utilized as prognostic indicator for evaluating cell proliferation, diagnosing diseases, and conducting research. Several different kinds of cancer have high Ki-67 expression, which simplifying the choice of treatment for individuals with various cancer types.

Background: Skip lymph node metastasis (SLNM) in papillary thyroid cancer (PTC) involves cancer cells bypassing central nodes to directly metastasize to lateral nodes, often undetected by standard preoperative ultrasonography. Although multiple models exist to identify SLNM, they are inadequate for clinically node-negative (cN0) patients, resulting in underestimated metastatic risks and compromised treatment effectiveness. Our study aims to develop and validate a machine learning (ML) model that combines elastography radiomics with clinicopathological data to predict pre-surgical SLNM risk in cN0 PTC patients with increased risk of lymph node metastasis (LNM), improving their treatment strategies.
