Photodynamic therapy for recurrent spinal diffuse midline glioma with a modest extension of overall survival: illustrative case.
Article in Journal of neurosurgery. Case lessons, 2026. 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
backgroundDiffuse midline glioma (DMG), a highly malignant CNS tumor, is classified as a World Health Organization grade 4 tumor. Its overall survival prognosis, even after standard treatment, is typically extremely poor. Photodynamic therapy (PDT) represents an innovative treatment modality with promising results for intracranial malignant gliomas. However, its use for spinal malignant gliomas has not yet been explored, despite their pathological similarity to intracranial malignant gliomas. OBSERVATIONS: The present case of a 28-year-old female patient with recurrent spinal DMG represents the first documented report concerning the effects of PDT on spinal malignant gliomas, with the pathological postmortem findings. Despite the successful application of PDT to the resection cavity of the spinal DMG, cervical spinal cord edema developed soon after surgery. The blood flow to the spinal cord parenchyma was thought to be altered but reversible. The patient's overall survival was 21 months after the initial surgery. LESSONS: This case highlights the potential of PDT as a feasible and promising adjunctive treatment for spinal malignant gliomas. The observed clinical course and pathological findings may provide valuable insights for future research and therapeutic development. https://thejns.org/doi/10.3171/CASE25751.
