Effect of gamma knife dose rate and tumor-specific factors on treatment outcomes in brain metastases: insights from a cohort study

This study highlights that dose rate does not significantly impact treatment outcomes in Gamma Knife radiosurgery for brain metastases, indicating that effective tumor control can be achieved even at lower dose rates. These findings provide reassurance regarding the efficacy of treatments utilizing decaying cobalt-60 sources and highlight the importance of patient- and tumor-specific factors in predicting radiosurgical outcomes.
