Gamma Knife Radiosurgery after Stereotactic Aspiration for Large Cystic Brain Metastases

摘要

ObjectiveSeveral treatment options have proven effective for metastatic brain tumors, including surgery and stereotactic radiosurgery. Tumors with cystic components, however, are difficult to treat using a single method. We retrospectively assessed the outcome and efficacy of gamma knife radiosurgery (GKRS) for cystic brain metastases after stereotactic aspiration of cystic components to decrease the tumor volume.
