Dose response test of patient-derived cancer organoids to irradiation.
Article in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: Patient-derived cancer organoids emerged as an innovative model in basic and translational medicine research, as well as precision medicine. However, most radiation oncologists are still unaware of the value of organoids in radiation oncology research, especially in precision radiation oncology. The methods for assessing organoid cell death after irradiation are also undefined. Methods: Three organoid lines were successfully established from the surgical specimens of rectal cancer patients. Genetic characterization of rectal cancer organoids was conducted. The survival of rectal cancer organoids after X rays irradiation was evaluated by image-based analysis and cell counting kit-8. Results: The three organoid lines displayed diverse architecture and captured heterogeneity of the tumors. The most frequently mutated genes and pathways among rectal cancer tumors also presented in rectal cancer organoids. Image-based analysis validated organoid survival after X rays irradiation, while cell counting kit-8 failed. The survival curves from imaging analysis were more representative, with an initial linear slope, followed by a shoulder, and tending to become straight again. This was the first study to investigate the appropriate testing method of using organoids to study cancer radiosensitivity. Conclusion: Cancer organoids were easy to use for the research of radiobiology of cancer. Image-based analysis is more accurate than cell viability (tested by cell counting kit-8) for studying cancer radiosensitivity via organoids.
