Abstract

The study objective: is to evaluate the results of using the Petrov Thyroid Cancer Score (PTCS) in 2018 and assess the diagnostic value of the original PTCS and modified PTCS. Materials and methods: PTCS, proposed in the N.N. Petrov National Medical Research Center of Oncology in early 2018, was tested in this institution in 310 patients, 99 of whom underwent surgery, mainly due to suspected malignancy of thyroid nodules or at the request of patients. Results: According to the standard histological evaluation, in 35 cases the process was considered benign (group Д), while in 61 cases - after exclusion of 3 medullary carcinomas - regarded as highly differentiated (according to previous classification) thyroid cancer (group Р). The average values of such components of PCTS as Bethesda_Score, TI-RADS_Score, Elasto_Score and body mass index (BMI) in group Р were significantly higher than in group Д. The sum of the scores of the used four parameters was not only higher in group Р, but also at a magnitude of ≥5.0 (62.3 % of observations in this group) it always corresponded to the diagnosis of thyroid carcinoma. At the same time, a similar histological conclusion was made, in particular, in respect of 14 patients (23 % of the group Р contingent) with the value of the mentioned sum <3.5. Of note, according to the preoperative cytological study, among these 14 cases 11 follicular neoplasms and 3 colloid nodules were found. Conclusion: A high value (≥5.0) of the sum of four selected parameters (3 from PTCS + BMI_Score) indicates an extremely high probability of detecting a tumor process, while in other cases (and not only under the assumption of follicular neoplasia presence), an additional diagnostic methods of research are needed.
