Normal Brain-Sparing Radiotherapy versus Whole Brain Radiotherapy for Multiple Brain Metastasis from Non-Small Cell Lung Cancer.
Article in Cancer research and treatment, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeThe efficacy and lower neurotoxicity of normal brain-sparing radiotherapy (NBS-RT) with systemic therapy in treating multiple brain metastases from non-small cell lung cancer (NSCLC) is underexplored. This study compares whole brain radiotherapy (WBRT) and NBS-RT for multiple brain metastases in NSCLC, focusing on treatment outcomes and leukoencephalopathy. Materials and Methods: This retrospective study included 503 patients with NSCLC with multiple brain metastases at a single center, treated with either WBRT or NBS-RT. Post-RT treatments included chemotherapy, targeted therapy, or immunotherapy. Main outcomes measured were intracranial control, overall survival (OS), and leukoencephalopathy incidence.
resultsIn this study, 441 patients received WBRT and 62 received NBS-RT, with median ages of 62 and 61 years, respectively. A significant portion of both groups, 77.3% in WBRT and 80.6% in NBS-RT, received post-RT systemic therapy. The median number of brain metastases was 10 for WBRT and 12 for NBS-RT, with median maximal diameters of 11.7 mm in WBRT and 14.4 mm in NBS-RT. After a median follow-up of 10.9 months for WBRT and 11.8 months for NBS-RT, there were no significant differences in intracranial progression (p=0.516) or OS (p=0.492) between the groups. However, WBRT patients had a higher incidence of leukoencephalopathy than NBS-RT patients (p=0.013).
conclusionNBS-RT combined with systemic therapy was as effective in treating multiple brain metastases as WBRT and was less toxic. NBS-RT-based strategies deserve further investigation in a prospective setting.
