For patients suffering from multiple brain metastases whole brain radiation therapy still constitutes a standard therapy. However, because of the risk of neurocognitive side effects as well as reduced local tumor control, employment of stereotactic radiosurgery (SRS) is becoming more common. The disadvantage of SRS alone may be poor intracranial tumor control because of frequent appearance of new distant brain metastases after therapy. In recent years hippocampal avoidance whole brain therapy has been shown to minimize treatment related side effects while reducing the rate of distant intracranial failure. In this study patients will be randomized to receive either hippocampal avoidance whole brain radiation therapy with integrated tumor boost (HA-WBRT+SIB) or stereotactic radiosurgery. The investigators hypothesize that HA-WBRT+SIB can improve intracranial tumor control compared to stereotactic radiosurgery, while avoiding additional neurocognitive side effects.
