Progression Free Survival Primary · 2 years

Progression-free survival (PFS) is defined as the time from the date of treatment start to the date of the first documented PD or death due to any cause. PFS will be based on the investigator's assessment of MRI, CSF studies and clinical presentation.

Overall Response Rate Secondary · 2 years

This study will use the Macdonald criteria. Specific lesions must be evaluated serially, and comparative analysis of changes in the area of contrast enhancement, as well as the non-enhancing component, should be performed. Complete Response: Complete disappearance of all measurable and non-measurable disease. No new lesions. Partial Response: Great than or equal to 50% decrease over the baseline in the sum of products of perpendicular diameters of all measurable lesions. no progression of non-measurable disease. No new lesions. Stable/No Response: Does not qualify for CT, PR, or progression. P
