This is a phase II randomized clinical trial. It is reported that avoidance of hippocampus during whole-brain radiotherapy (WBRT) had benefits in preservation of memory for patients, and the use of concurrent TMZ in radiotherapy for patients with brain metastases benefited for treating outcome.~The purpose of this study is to evaluate the effects on neurocognitive function of whole-brain radiotherapy with/without TMZ concurrent chemotherapy or avoidance of hippocampus for patients of brain metastases, as well as the feasibility and risk of avoidance of hippocampus during whole-brain radiotherapy.
