Must not have
Be younger than 18 years old
Screening 3 weeks
Treatment Varies
Follow Up10 years

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Arm I (SRS)Experimental Treatment2 Interventions
Patients undergo SRS over 1 day (in some cases several days).
Group II: Arm II (HA-WBRT, memantine)Active Control3 Interventions
Patients also undergo HA-WBRT QD for 2 weeks in the absence of disease progression or unacceptable toxicity. Patients will also receive memantine PO QD or BID for up to 24 weeks in the absence of disease progression or unacceptable toxicity.
