Cancer in children is a very important issue in pediatrics. The least satisfactory treatment outcome occurs among patients with clinically advanced neuroblastomas. Despite much research, the biology of this tumor still remains unclear, and new prognostic factors are sought. The Bmi-1 gene product is a currently highly investigated protein which belongs to the Polycomb group (PcG) and has been identified as a regulator of primary neural crest cells. It is believed that Bmi‑1 and N-myc act together and are both involved in the pathogenesis of neuroblastoma. The aim of the study was to assess the potential prognostic value of Bmi-1 protein and its relations with mechanisms of proliferation and apoptosis in the neuroblastoma group of tumors.
