Irinotecan and Whole-Brain Radiation Therapy in Treating Patients With Brain Metastases From Solid Tumors
Brain and Central Nervous System Tumors, Cognitive/Functional Effects, Long-term Effects Secondary to Cancer Therapy in Adults
About this trial
This is an interventional treatment trial for Brain and Central Nervous System Tumors focused on measuring cognitive/functional effects, poor performance status, long-term effects secondary to cancer therapy in adults, long-term effects secondary to cancer therapy in children, adult tumors metastatic to brain, unspecified adult solid tumor, protocol specific, unspecified childhood solid tumor, protocol specific
Eligibility Criteria
DISEASE CHARACTERISTICS:
Diagnosis of brain metastasis from a histologically confirmed solid tumor, meeting the following criteria:
