Background: In Belarus with many papillary thyroid carcinoma (PTC) cases developedin patients because of the post-Chernobyl irradiation the need for prophylactic dissections of the central and lateral compartments of the neck is never questioned. As a result, we collected hundreds of PTC cases in children and adolescents that provide excellent information on the real initial extent of the disease, subsequent treatment and follow-up.

Aims: To identify factors associated with nodal disease (and the degree of their involvement) and to predict the risk of recurrent/persistent disease in this cohort of patients using clinical and morphological characteristics of the primary thyroid tumour and its lymph-node metastases in the central compartment of the neck.

Material and Methods: All the patients aged <19 years old at presentation with PTC who were treated with total thyroidectomy and lymph nodes dissections (in the central and lateral compartments of the neck) according to the extent of disease at the time of diagnosis (n = 509).

Results: The metastatic ratio index (MRI) was an independent variable that potentially influence the decision to carry out lateral lymph nodes compartment surgery in addition to routinely performed central lymph nodes dissection. A nomogram with excellent discriminatory ability and accuracy in predicting probability of ipsi or bi-lateral nodal disease was created. Clinical and pathological characteristics associated with relapse were identified.

Conclusion: The results of our study allowed us to supplement and refine the algorithms proposed by specialists of the American Thyroid Association.
