The aim of the study was to evaluate the efficacy and safety of nivolumab in pediatric patients with various types of highly malignant advanced tumors. Patients and Methods: Ten patients with a median age of 15.1 years were included in the study. The indications for treatment were: malignant skin melanoma (n=5), brain tumor (n=2), malignant melanoma of the brain (n=1), Hodgkin lymphoma (n=1) and soft tissue sarcoma (n=1). Results: Complete disease remission was observed in 4 patients. Overall survival at 24 months from diagnosis for the entire group was 0.36. Two patients receiving combination therapy of nivolumab and ipilimumab did not achieve a remission. Adverse events of immunotherapy were observed in 4/10 patients. Conclusion: Nivolumab is a promising option in pediatric advanced malignancies. Treatment with immunotherapy was relatively well tolerated, and emerging side-effects were manageable.
