Efficacy analysis of brain radiotherapy in EGFR mutation non-small cell lung cancer with brain metastasis: a retrospective study.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesPatients with epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) are at a heightened risk of developing brain metastases (BM). EGFR-tyrosine kinase inhibitors (TKI) are standard treatment for EGFR-mutated NSCLC. However, the necessity and optimal approach of brain radiotherapy for NSCLC patients with EGFR mutation remain inconclusive. We aimed to answer these questions by retrospectively analyzing the efficacy of radiotherapy in patients with BM from NSCLC with EGFR mutations.
methodsPatients with EGFR- mutant NSCLC and BMs who were diagnosed between January 1, 2018 and December 31, 2022 were included. According to treatment methods those patients were divided into whole brain radiotherapy (WBRT) plus EGFR-TKI (WBRT group), stereotactic radiotherapy (SRT) plus EGFR-TKI (SRT group) and EGFR-TKI alone (TKI-only group). Propensity-score-matching (PSM) was performed to minimize the effect of possible confounding factors and to balance treatment groups.
resultsA total of 142 patients were included in this study. The median follow-up time was 22 months (range, 3.0-43.0 months). In the PSM cohort, the median intracranial progression free survival (iPFS) was 14, 30, 12 months and the median overall survival (OS) was 27 months, not reach and 33 months in WBRT group, SRT group and TKI-only group, respectively. Compared with the other two groups, SRT group significantly improved iPFS and OS (p < 0.05). And the local progression rate of intracranial lesions in SRT group was significantly reduced (p < 0.05).
conclusionThis study showed that SRT combined with TKI may improve iPFS and prolong survival in patients with EGFR mutations in BMs from NSCLC.
