Eligibility
Inclusion criteria
Inclusion criteria: Pre-registration inclusion criteria 1. Age 18 years or more 2. KPS 70 or more, or ECOG 0-2 3. Histologically proven malignancy 4. CT and/or MRI performed within 1 month prior registration confirmed brain metastases 2-15 lesions 5. All brain metastases 3 cm. or smaller 6. Life expectancy 6 months or more according to brainmet.gpa (for primary lung cancer, breast cancer, melanoma, renal cell carcinoma and GI malignancy), otherwise evaluated by treating physician 7. Progressive brain metastasis following systemic treatment with effective intracranial activity is eligible 8. Resection of brain metastasis with planned postoperative radiation is eligible Additional inclusion criteria at time of MRI simulation 1. Eligible for HA-WBRT+SIB and/or SRS/SRT - No lesion within 5 mm. around hippocampi, otherwise ineligible for HA-WBRT+SIB - No lesion closed or adjacent to critical structures (e.g. optic pathways, cranial nerve, brainstem) that may preclude safe radiation, otherwise ineligible for SRS/SRT and/or HA-WBRT+SIB 2.

Primary germ-cell tumor, small-cell carcinoma, or lymphoma 8. Known case of psychiatric disorders or neurodegenerative diseases Additional exclusion criteria after radiotherapy treatment planning - Unable to achieve safe radiotherapy treatment plans (e.g. major deviation from treatment protocol, unacceptable dose constraint to critical structure) for both SRS/SRT and HA-WBRT after switching from SRS/SRT to HA-WBRT+SIB or vice versa
