Context: Treatment of Recurrent Childhood Medulloblastoma and Other CNS Embryonal Tumors / Treatment Options

At the time of relapse, a complete evaluation for extent of recurrence is indicated for all embryonal tumors. Biopsy or surgical resection may be necessary for confirmation of relapse because other entities, such as secondary tumors and treatment-related brain necrosis, may be clinically indistinguishable from tumor recurrence. The need for surgical intervention must be individualized based on the initial tumor type, the length of time between initial treatment and the reappearance of the lesion, and clinical symptoms.
