Choroid plexus carcinoma (CPC) is a rare malignant tumor arising from the epithelium of the choroid plexus of the brain. More than 80 % of CPCs occur in children. Mutations in the TP53 gene is played the main role in the pathogenesis of these tumors. Choroid plexus carcinomas in 40 % of cases are associated with Li–Fraumeni syndrome. Survival rates in patients with CPC and Li–Fraumeni syndrome are extremely low. The standards of the therapy for patients with CPC are not defined. The extent of

The role of adjuvant therapy in CPC remains unclear: doses and volumes of radiation therapy (RT), combinations of chemotherapeutic drugs, timing, and a combination of RT and chemotherapy (CT) have not been identified. Also, there is neither a standard CT regimen nor a prospective international study assessing the efficacy and toxicity of various combinations of cytostatics in patients with CPC. The article presents an overview of the existing molecular genetic changes, existing methods for the diagnosis and treatment of choroid plexus carcinoma.
