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

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBrain metastases (BM) are among the most common intracranial tumors. Despite advances in multimodal therapy for newly diagnosed BM, the management of recurrent BM remains a clinical challenge. Due to the lack of robust data, there is currently no consensus regarding optimal salvage treatment for recurrent BM.
methodsInstitutional data (2016–2025) and published data from the literature (2011–2025) were analyzed with respect to overall survival (OS) and progression-free survival (PFS) after recurrence. Survival data were extracted from Kaplan-Meier curves of the selected studies using the R package IPDfromKM and pooled survival analyses were performed.
resultsIn a pooled analysis of 776 patients, local surgical re-resection after recurrence was associated with significantly longer survival compared to both non-surgical management (median 14.74 [95% CI: 11.68–17.80] vs. 10.34 months [95% CI: 8.59–12.08]; HR: 0.664; p < 0.001) and only repeat stereotactic radiosurgery (Re-SRS) (median 14.74 months [95% CI: 10.51–18.98] vs. 10.97 months [95% CI: 9.1–12.84]; HR: 0.62; p < 0.001). Among patients who underwent local re-resection, gross total resection (GTR) led to markedly improved OS compared to subtotal or incomplete resection (median 23.97 months [95% CI: 15.95–31.99] vs. 7.06 months [95% CI: 5.21–8.90]; HR: 0.400; p < 0.0001). The addition of adjuvant re-radiotherapy after re-resection did not result in a significant survival benefit (p = 0.357). Regarding PFS, patients treated with local re-resection alone had the longest median PFS (43.23 months), significantly outperforming both those receiving re-resection plus adjuvant re-SRS (29.92 months; HR = 0.529; p < 0.001) and those treated with Re-SRS alone (15.79 months; HR = 3.031; p < 0.001).
conclusionsThis 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.
