Treatment modalities in recurrent brain metastases: a combined institutional and individual patient data meta-analysis of post-recurrence survival and local progression-free survival

This study highlights the role of local re-resection in improving survival among patients with recurrent brain metastases amenable to repeat GTR. Re-SRS remains a valuable salvage option, particularly for patients in whom GTR is not feasible. While adjuvant re-radiotherapy following re-resection did not demonstrate a clear survival advantage in our analysis, it may offer additional local control in selected cases. These findings emphasize the importance of individualized, multidisciplinary decision-making to tailor salvage strategies to patient- and tumor-specific factors.
