Patients with CNS germ cell tumors who present with elevated serum tumor markers at diagnosis and achieve a complete biochemical and radiological remission may not need surveillance MRI scans to monitor for recurrence, but MRI scans may be considered to monitor for secondary malignancy. If other series replicate these findings, surveillance via monitoring of serum tumor markers only could be done and omission or reduction of the frequency of surveillance MRI scans could save a significant amount of money.
