Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Based on evidence that radiation-induced damage to the hippocampus plays a considerable role in neurocognitive decline after cranial irradiation, hippocampal-sparing whole brain radiation therapy (HS-WBRT) has been proposed. This study will investigate the neurocognitive function and prognosis between HS-WBRT and conventional WBRT for the treatment of brain metastases from breast cancer.

Intervention Type RADIATION

Hippocampal-sparing WBRT (HS-WBRT) group

Hippocampal-sparing whole brain radiotherapy is performed using modern intensity-modulated radiotherapy (IMRT) technique to avoid conformally the hippocampal neural stem-cell structure during WBRT. Prescription dose is 37.5 Gy in 15 fractions.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria
