Abstract

Objective . To study the value of a mathematical model of lymph node (LN) metastasis according to magnetic resonance imaging (MRI) data in cervical cancer (CC) in a comparative aspect with the traditional MRI criterion of LN metastasis (the size on the short axis being ≥ 1.0 cm) for assessing the prognosis of the disease. Materials and methods . To assess the CC prognosis, the indices of one-year, five-year cancer-specific survival (CSS) rates of 100 patients were analyzed in a comparative aspect: if metastatic lymph nodes (MLNs) are detected according to MRI data based on the use of the mathematical model for the MLN diagnosis and the traditional MRI criterion. Results . The comparison of five-year CSS indices for groups of patients with a favorable prognosis (N0) using the traditional criterion and the mathematical model has revealed a statistically significant difference (р < 0.001). Conclusion . The developed mathematical model of LN metastasis according to MRI data makes it possible to predict the unfavorable development of CC, as well as serves as a guide for individual therapy.
