Tracing metastatic spread in pediatric solid tumors using copy number and targeted deep sequencing.

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
The most common cause of death in pediatric cancer patients is a treatment-resistant tumor, compounded by metastatic spread, making surgery, radiation therapy, and chemotherapy unfeasible as curative treatment options. However, the mechanisms behind metastatic spread in pediatric tumors remain largely unexplored. We conducted whole-genome copy number profiling on 171 primary tumor and metastases samples from 17 patients with neuroblastoma, Wilms tumor, or gonadal tumors, and performed targeted deep sequencing on a subset. Phylogenetic reconstruction enabled spatiotemporal tracking of subclones. In total, 11 of 17 patients displayed at least one metastasis arising earlier, defined as occurring before the most recent common ancestor in the primary tumor. In eight patients, metastatic spread was observed several times during tumor evolution, with different subclones from the same primary tumor having metastatic capability, even colonizing the same site. Strikingly, dissemination between metastases (intermetastatic spread) occurred in eight of nine patients with metastases in at least two different sites, indicating that this is a common phenomenon in pediatric malignancy. © 2025 The Author(s).
