The assessment of aggressiveness and risk of death in papillary thyroid cancer in children is currently based on clinical criteria. To ensure a more accurate risk stratification, new criteria and various molecular genetic markers are constantly being sought. The article studied the dependence of the clinical and pathological manifestations of papillary thyroid cancer in children on the level of expression of various microRNAs and the presence of the BRAF mutation. It was found that the BRAF mutation was present in 20.4% of cases, while the dependence of the clinical behavior of cancer on the BRAF mutation was not established. Of the 14 microRNAs studied, statistical differences were obtained for oncogenic miR-146b, -221, -31, and oncosuppressive miR-144, which correlated with signs such as extrathyroid tumor growth, multi-focus, and metastasis to the neck lymph nodes.

Stratifications of the risk of recurrence and mortality in papillary thyroid cancer (PTC) are currently based on clinical criteria. In order to provide a more accurate assessment of the risk of relapse, new criteria, such as molecular genetic markers, are constantly being sought. The most studied of these markers is the BRAF mutation. The aim of the work was to study the dependence of clinical and pathological manifestations of papillary thyroid cancer on the presence of a BRAF mutation. The retrospective study included 212 patients with PTC. The dependence of the BRAF mutation on the patient’s gender, age, multifocality, presence of regional and remote metastases, extrathyroid invasion, clinical stage, and risk of relapse was studied. A single tumor was found in 196 (92.4%) cases, and a multifocal one in 16 (7.6%). Macroscopic extrathyroid invasion was observed in 80 (37.7%) patients. Metastases in regional lymph nodes were found in 83 (39.2%) patients, in 12 (5.7%) cases, the presence of distant metastases was detected. It was found that the BRAF mutation was present in 128 (60.4%) patients. There was no statistically significant association between the presence of the mutation and clinical and pathological manifestations of PTC, except for age. The incidence of the BRAF mutation in patients with PTC in young, middle, elderly and senile age was 3.8-35 times higher than in children and young men. It was found that the frequency of detection of the BRAF mutation increases with the age of the patient and has a linear relationship. It was concluded that the BRAF mutation can’t be used as an isolated marker of aggressive flow and a criterion indicating an increased risk of relapse of PTC.

Among the factors determining the relapse/persistence of papillary thyroid cancer in children and adolescents the most important are the age of the patient (p= 0.003), the presence of concomitant background pathology (p

Papillary thyroid cancer often presents with cervical lymph node involvement and has a high incidence of recurrence, which requires routine follow-up with ultrasound imaging. Elastography is a novel ultrasound technique that has been demonstrated to be effective clinically in detecting tissue pathology in areas such as the liver and breast. Preliminary data suggest that it may be effective in screening tissues in the neck for malignancy, specifically cervical lymph nodes. However, diagnostic criteria and elastographic techniques vary significantly among the studies we have reviewed, which all tend to focus on populations of patients with many different types of primary malignancies. Further research is required on the feasibility of creating standardized and reproducible clinical criteria in a specific patient population. To study the clinical utility of elastography in cervical lymph nodes, patients with diagnosed papillary thyroid carcinoma may serve as an ideal population because of their need for ultrasound surveillance and the propensity of papillary thyroid cancer to metastasize to and recur in cervical lymph nodes. We will review the limitations, techniques, and reported clinical utility of elastography on cervical lymph nodes and its potential as a screening modality for papillary thyroid cancer.

Introduction. In the last decade several population studies on the association of the genes NKX2-1 and FOXE1 with sporadic papillary thyroid cancer were conducted. In the Kazakh population of similar work to date were not conducted. The aim of this study was to study the genetic association of the FOXE1 (rs9655313) and NKX2-1 (rs944289) oncomarkers with papillary thyroid cancer in the Kazakh population. Materials and methods. We conducted a case-control study that allows us to retrospectively evaluate the association of NKX2-1 and FOXE1 genes and papillary thyroid cancer. Results. The frequency distribution of FOXE1 rs965513 polymorphism in the group of papillary thyroid cancer and the control group detected by healthy individuals was significantly different (χ2 = 100.09, D.f. = 2, p = 0.000). In the group of cases, the AA genotype (17.5%) was in three times more often compared with the control group (5.1%). The GG variant had a lower frequency in the group of persons of papillary thyroid cancer (37.9%) against the control group (61.4%), the odds ratio (OR) in the FOXE1 rs965513 group was 2.367. The distribution of the NKX2-1 (rs944289) polymorphism frequencies in the compared groups of values were significantly different (χ2 = 100.09, D.f. = 2, p = 0.000). In the group of cases, the genotype of TT (30.5%) against the control group (20.7%) was 1.5 times more common. The SS variant had a lower frequency of occurrence in the group of persons of papillary thyroid cancer (19.8%) against the control group (28.9%), OR in NKX2-1 (rs944289) group was 1.46. Conclusion. Carrying out screening for carriers of FOXE1 rs965513 and NKX2-1 (rs944289) can become an effective means of early diagnosis with a high frequency of its spread and associations with cases of papillary thyroid cancer in the Kazakh population.
