Safety and efficacy of salvage reirradiation for recurrent high-grade gliomas: a retrospective analysis.
Article in Japanese journal of radiology, 2026. 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
purposeTo assess the feasibility, safety, and clinical outcomes of salvage reirradiation, using intensity-modulated radiotherapy (IMRT) with a total dose of 30 Gy and cumulative equivalent dose in 2 Gy fractions (EQD2) limited to ≤ 96 Gy in patients with recurrent high-grade gliomas. MATERIALS AND
methodsThis retrospective study included 24 patients with recurrent high-grade gliomas who underwent IMRT-based reirradiation between 2014 and 2021. Treatment planning was performed using computed tomography-magnetic resonance imaging fusion images, and radiotherapy was delivered via IMRT or volumetric-modulated arc therapy. No concurrent chemotherapy was administered, and the cumulative EQD2 to the brain was restricted to 96 Gy.
resultsThe median follow-up was 8 months (range, 1-31 months). The median overall survival was 8 months, with 1- and 2-year overall survival rates of 29% and 4%, respectively. No grade ≥ 2 toxicity or cases of radiation necrosis were observed. All patients completed the planned treatment course without interruption.
conclusionSalvage reirradiation using IMRT with an EQD2 limited to ≤ 96 Gy was a feasible and well-tolerated treatment strategy for select patients with recurrent high-grade gliomas. This approach may offer a modest survival benefit with minimal toxicity and warrants further investigation in prospective trials.
