Effectiveness of metronomic chemotherapy in a child with medulloblastoma: A case report

Medulloblastoma (MB) is one of the most common pediatric malignant tumors arising from the central nervous system with an unknown etiology and variable prognosis. Relapsed or refractory MB in pediatric patients after intensive anticancer therapy (chemo-, radiotherapy) is associated with treatment resistance and poor survival prognosis. Metronomic chemotherapy in combination with mTOR inhibitors may have advantages due to an alternate mechanism of cytotoxicity and a favourable adverse effects profile. Furthermore, it is considered to be a prospective anticancer regimen regardless of the presence/absence of molecular targets. The present study reported a successful result of this treatment option with optimal tolerability in relapsed MB in a pediatric male patient and highlighted the advantages for a selected group of patients.
