Study Bendamustine Concurrent Whole Brain Radiation Brain Metastases From Solid Tumors

Approximately 15-24 study patients will be enrolled in this Phase I trial. Study patients will receive a weekly dose of IV bendamustine with whole brain radiation therapy for 3 weeks and then receive a fourth dose of IV bendamustine one week after completion of whole brain radiation therapy. The first dose of IV bendamustine will be given when whole brain radiation is initiated.
