Comparative Analysis of Recurrent Glioblastoma Target Contours via
Article in Advances in radiation oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Purpose: Glioblastoma (GBM) recurrence poses challenges in radiation therapy treatment planning because reirradiation has limited leeway needed for precise target delineation. Although effective radiotracers are emerging for treatment planning, comparisons of Methods and Materials: A 37-year-old female patient with recurrent Isocitrate dehydrogenase (IDH)1/2 wild-type GBM underwent MRI, MET-PET, and PSMA-PET scans. Target delineations were performed, and volumes were compared using the Dice similarity coefficient, conformity index, and overlap volume, considering different planning target volume margins. Results: We found that MET-PET and MRI volumes showed superior agreement compared with PSMA-PET across all similarity parameters, indicating a more marked discrepancy between PSMA-PET and other modalities. Increasing planning target volume margins demonstrated progressive convergence in intervolume discrepancies. Notably, PSMA-PET delineated larger volumes extending beyond MRI-based volumes. Conclusions: MRI alone may not suffice for target delineation in recurrent GBMs. PET imaging modalities offer complementary insights. Combined PET-MRI guidance could improve tumor boundary detection in target delineation for reirradiation. Prospective trials are necessary to ascertain its impact on patient outcomes.
