Same-day stereotactic radiation with reduced planning margins for growing or changing brain metastases
This trial will try to see if doing MRI planning and stereotactic radiation on the same day, with either a 0 mm or 1 mm treatment margin, helps adults with growing or unstable brain metastases stay on target and reduce side effects.
-
Characterizing immune cells in malignant brain tumors
This study is trying to understand how immune cells behave in people with malignant brain tumors by looking at their blood and tumor samples before and after surgery.
-
Registry of patients with brain tumors treated with GammaTiles
This study is testing how well GammaTiles treatment works for people with brain tumors after surgery, looking at their health and quality of life over five years.
-
Comparing GLIADEL and Stereotactic Radiosurgery for Metastatic Brain Tumors
This study is testing whether a local chemotherapy treatment called GLIADEL can help prevent brain tumors from coming back after surgery, compared to a treatment called stereotactic radiosurgery, for adults with metastatic brain tumors.
