1 · What the graph read from 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.

2 · The registry

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

backgroundFiducial markers are commonly used to guide precise radiotherapy in prostate cancer patients. While intraprostatic migration has been described, transcutaneous displacement during biopsy is exceedingly rare. We report the first known case of transcutaneous fiducial marker removal during transperineal prostate rebiopsy. CASE PRESENTATION: A 62-year-old man with high-risk prostate cancer underwent radiotherapy with gold fiducial markers in 2020. Following two biochemical recurrences, transperineal MRI/ultrasound fusion-guided biopsy was performed in 2024. Increased resistance was encountered during the final biopsy pass, and a gold marker was found embedded in the core sample and was inadvertently removed transcutaneously. The procedure was well tolerated, and no complications occurred.

conclusionsThis case illustrates that even long after implantation, fiducial markers may still become dislodged during prostate interventions. While the event was asymptomatic, it highlights the importance of procedural awareness and planning to prevent potential compromise of radiotherapy accuracy in future cases.
