Overall survival following whole-brain radiotherapy for brain and leptomeningeal metastases from solid tumors.
Article in Tzu chi medical journal. 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
Objectives: Brain and leptomeningeal metastases are relatively common complications of advanced solid tumors, occurring in an estimated 20%-40% of cases and significantly reducing survival and quality of life. Despite advancements in systemic therapies and stereotactic radiosurgery, whole-brain radiotherapy (WBRT) remains the standard treatment. This study evaluates overall survival (OS) and prognostic factors in patients with brain and leptomeningeal metastases treated with WBRT at a single institution. Materials and Methods: We retrospectively analyzed 228 patients with brain and leptomeningeal metastases treated with WBRT between December 2012 and April 2024. Patients received either 30 Gy in 10 fractions or 20 Gy in five fractions. Prognostic factors were assessed using multivariate Cox proportional hazards regression. Results: The median OS for the entire cohort was 5.5 months (95% confidence interval: 3.8-6.2). Female patients had a statistically significantly longer OS (8.5 months) compared with male patients (3.8 months, Conclusion: This study confirms that WBRT offers modest survival benefits, consistent with prior research. While factors such as patient sex and ECOG performance status influence outcomes, the clinical impact of WBRT on leptomeningeal metastases remains limited. Survival outcomes are significantly impacted by factors such as patient sex and performance status, highlighting the need for personalized patient evaluation.
