White Matter Alterations

Brain metastases are a source of much morbidity and mortality in adults with primary solid malignant tumors. With improvements in systemic therapy that prolong survival but have limited central nervous system penetration, patients with brain metastases are at increasing risk of developing and experiencing long-term side effects from treatment of brain metastases. The overarching goal of this study is to better understand the determinants of RT-associated changes in white and gray matter function and associated neurocognitive decline.
