Impact of hospital volume on mortality for brain metastases treated with radiation.
Article in Reports of practical oncology and radiotherapy : journal of Greatpoland Cancer Center in Poznan and Polish Society of Radiation Oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe impact of hospital volume on cancer patient survival has been demonstrated in the surgical literature, but sparsely for patients receiving radiation therapy (RT). This analysis addresses the impact of hospital volume on patients receiving RT for the most common central nervous system tumor: brain metastases. MATERIALS AND
methodsAnalysis was conducted using the National Cancer Database (NCDB) from 2010-2015 for patients with metastatic brain disease from lung cancer, breast cancer, and colorectal cancer requiring RT. Hospital volume was stratified as high-volume (≥ 12 brain RT/year), moderate (5-11 RT/year), and low (< 5 RT/year). The effect of hospital volume on overall survival was assessed using a multivariable Cox regression model.
resultsA total of 18,841 patients [9479 (50.3%) men, 9362 (49.7%) women; median age 64 years] met the inclusion criteria. 16.7% were treated at high-volume hospitals, 36.5% at moderate-volume, and the remaining 46.8% at low-volume centers. Multivariable analysis revealed that mortality was significantly improved in high-volume centers (HR: 0.95, p = 0.039) compared with low-volume centers after accounting for multiple demographics including age, sex, race, insurance status, income, facility type, Charlson-Deyo score and receipt of palliative care.
conclusionHospitals performing 12 or more brain RT procedures per year have significantly improved survival in brain metastases patients receiving radiation as compared to lower volume hospitals. This finding, independent of additional demographics, indicates that the increased experience associated with increased volume may improve survival in this patient population.
