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

To develop an optimized genomic medicine platform for pediatric cancers, a nationwide cancer genome profiling project was conducted from January 2022 to February 2023 in collaboration with the Japan Children's Cancer Group. This prospective observational study analyzed matched blood and FFPE tumor samples from patients aged 0-29 years with solid tumors. Genomic analysis used the TOP2 hybrid capture-enrichment system, targeting 737 and 455 genes in the DNA and RNA panels, along with allele-specific genome copy number alterations. A total of 210 patients from 50 institutions were enrolled across Japan (median age, 8 years; range, 0-25). Of these, 154 (77%) were enrolled at diagnosis or during/after initial treatment and 56 (27%) at disease progression or relapse. The TOP2 findings had great benefits in clarifying the diagnosis of pediatric solid tumors. Among the 204 patients with genomic results, 147 (72%) had potentially actionable findings, including diagnostic, prognostic, and therapeutic findings in 111 (54%), 61 (30%), and 64 (31%), respectively. Oncogenic fusions were noted in 45 (23%) patients. A copy number alteration was identified in at least one genomic region in 170 (83%) patients. Two patients exhibited a high tumor mutation burden. Seventeen (8%) patients harbored a germline pathogenic/likely pathogenic variant in cancer-predisposing genes. This study highlighted the feasibility of implementing a nationwide precision medicine platform and the clinical utility of the TOP2 system for pediatric cancers. The results support the integration of genomic data into the standard clinical care of pediatric patients with cancer, both at diagnosis and at relapse.
