Whole Brain IMRT for Brain Tumor

In this study the patient will receive either whole brain radiation therapy given by intensity modulated radiation therapy (IMRT) or standard conventional radiation. In IMRT therapy radiation dose to the parts of the brain that do not contain tumors is reduced. This study will look to see if this approach results in less hair loss or fewer memory Problems, as compared to the standard technique. The study will also look at the effectiveness of both techniques in controlling the growth of the tumor.
