Brief summary
This clinical trial was designed to investigate the efficiency and toxicity of tomotherapy as primary radiotherapy for multiple brain metastases.
Detailed description
This is a single-arm, single center, phase II trial to investigate the feasibility and toxicity of tomotherapy as primary radiotherapy for multiple brain metastases(≥3 lesions).
Interventions
Whole brain radiation (WBRT) with 38-40Gy in 20 fractions and concurrent boost of 60-70Gy of the lesions. TMZ is used if necessary: concomitant TMZ: 75mg/m2 adjuvant TMZ: 150mg/ m2\*5d, q28d, up to 6cycles.

Unable or unwilling to comply with the study protocol.The expected survival time is less than 3 months. Patients who are anticipated in other clinical trials of brain metastases. Patients who has been treated with WBRT. Pregnant patients or female patients whose HCG is positive. Unsuitable to participate in study, that in the opinion of the treating physician.
