The safety and efficacy of dabrafenib plus trametinib for patients with brain metastatic melanoma: a systematic review and meta-analysis.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 common complications of metastatic cancer and typically occur in patients with melanoma. This study aims to investigate the dabrafenib plus trametinib for patients diagnosed with melanoma brain metastasis (MBM).
methodThis review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). PubMed, Embase, Scopus, and Web of Science were searched until January 1, 2025. Data on the neurological progression-free survival (PFS), overall survival (OS), radiological response rate, whether intracranial and total, and adverse events were collected. Quality assessment of the studies was conducted using the Newcastle-Ottawa Scale (NOS). The STATA version 17.0. has been used for analysis of the outcomes.
resultsEleven studies met the inclusion criteria. Our results showed pooled 6-month OS rate of 76% (95% CI [69-84%]), 1-year OS of 45% (95% CI [38-51%]), 6-month PFS rate of 46% (95% CI [40-52%]), 1-year PFS of 22% (95% CI [13-30%]), disease control rate (DCR) of 71% (95% CI [61-80%]), overall response rate (ORR) of 45% (95% CI [33-57%]), complete response rate (CRR) of 4% (95% CI [0-11%]), partial response rate (PRR) of 47% (95% CI [31-63%]), progressive disease rate (PDR) of 29% (95% CI [13-44%]), and stable disease rate (SDR) of 21% (95% CI [14-27%]). The pooled intracranial CRR, intracranial PRR, intracranial SDR, and intracranial PDR were 4% [95% CI: 1-8%], 42% [95% CI: 32-53%], 24% [95% CI: 18-31%], and 24% [95% CI: 13-34%], respectively.
conclusionThese findings underscore the effectiveness of dabrafenib plus trametinib in managing MBM, offering potential benefits in disease control and patient outcomes.
