Progress in stereotactic radiotherapy for patients with brain metastases

MRI has an important role in diagnosis, treatment and followed up for patients with brain metastases. The volume of metastases, state of the primary disease, kps, extracranial metastases, recursive partitioning analysis (RPA) class, adjuvant whole brain radiation therapy (WBRT) were the most importance factors associated with the effect of stereotactic radiotherapy. Treatment of brain metastases using stereotactic radiosurgery alone will to be the mainstay of management for patients with brain metastases. The value of fraction stereotactic radiotherapy in treatment brain metastases was not confirmed. (authors)
