Brief Summary
Brain metastases are the most common brain tumors in adults. It is estimated that around 10-30% of cancer patients would develop brain metastases during the course of their illness. Whole brain radiotherapy (WBRT) is the treatment of choice for the majority of patients with brain metastases. WBRT yields high radiologic response rate (27\~56%) and is effective in rapid palliation of neurologic symptoms as well as prolongs time to neurocognitive function decline caused by intracranial lesions. By using conventional fractionation, 33% of patients developed late neurocognitive toxicity while memory impairment was the most common symptom. The incidence is even higher when a formal and sensitive neurocognitive assessment was prospectively evaluated. With more long-term survivors nowadays, it has become increasingly important to minimize neurocognitive function decline and maintain quality of life in patients with brain metastasis. The function of hippocampus is cooperation in learning, consolidation and retrieval of information and essential for formation of new memories. Bilateral and unilateral radiation injury of the hippocampus is known to alter learning and memory formation. Several preclinical studies support the hypothesis of hippocampus-mediated cognitive dysfunction by ionizing radiation. Clinical studies show increase in radiation dose to hippocampus is associated with subsequent neurocognitive function impairment in adult and pediatric patients. Furthermore, the preliminary result of Radiation Therapy Oncology Group (RTOG) 0933 suggested hippocampal avoidance significant reduce the mean relative decline at 4 months from 30% in historical cohort with WBRT to 7% in experimental cohort. Previous studies showed brain structures other than hippocampus are also associated with radiation-induced decline in neurocognitive function. There is presence of placebo effect for interventions seeking improvement in neurocognitive function. In present study, a single blind randomized phase II trial is designed to investigate the effectiveness of neurocognitive function preservation using conformal WBRT with or without hippocampal avoidance.

Eligibility Criteria
You may qualify if:
- Patients with a histologic diagnosis of non-hematopoietic malignancy and radiographic evidence of brain metastases
- Patients with brain metastasis outside a 5-mm margin around either hippocampus on gadolinium contrast enhanced MRI obtained within 30 days prior to registration
- Patients with brain metastasis who have not been or will not be treated with stereotactic radiosurgery (SRS) or have received SRS for≤ 5 intracranial metastatic lesions
- No evidence of leptomeningeal metastasis on gadolinium-enhanced MRI within 30 days prior registration
- Age ≥ 20 years
- Karnofsky Performance Status ≥ 60%
- Life expectancy of ≥ 4 months.

- Patients must be able to comply with the study protocol and follow-up schedules and provide study- specific informed consent
You may not qualify if:
- Patients fulfill any of the following criteria will be excluded from this trial
- Prior radiotherapy to brain or SRS to \> 5 intracranial metastatic lesion(s) or the biological equivalent dose in 2-Gy fractions was greater than 7.3 Gy to 40% of the volume of bilateral hippocampus from prior SRS
- Serum creatinine \> 2.0 mg/dL within 30 days prior registration
- Contraindication to MRI such as implanted metal devices or foreign bodies, severe claustrophobia
- Patients with leptomeningeal metastases
- Severe, active comorbidities which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and adverse events of the protocol, or limit compliance with study requirements, defined as follows:
- Uncontrolled active infection requiring intravenous antibiotics at the time of registration
- Transmural myocardial infarction ≤ 6 months prior to registration
- Unstable angina or congestive heart failure requiring hospitalization ≤ 6 months prior to registration
