Multimodal Combination Treatment in a Patient-Centered Approach is Associated with Improved Outcome in Relapsed/Refractory Sarcomas in Children: A Comparative Single-Institution Real-World Analysis.
Article in Oncology and therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionTargeted treatment in children, especially with sarcomas, has limited utility due to small numbers of patients with driving mutations. Multimodal combination treatment and patient-centered approach combine treatment modalities administered based on comprehensive biological and empirical factors. Together, they extend precision oncology beyond a single molecular target.
methodsThis is a single-institution real-world study of children and young adults diagnosed between 2004 and 2021, with relapsed/refractory and/or primary metastasizing high-risk solid tumors who underwent molecular tumor board. Patients underwent comprehensive biological examination of the tumor. A treatment recommendation was made subsequently combining empirical and biological data. All progressive/recurrent events during disease follow-up were analyzed using a hierarchical survival modeling approach combining individual patient time series in a meta-analytic framework for comparative analysis of treatment effects.
resultsA total of 93 patients were included in the analysis who experienced 189 events. Overall survival was 7.5 years. A comparative analysis utilizing event-free survival (EFS) ratio was possible in an ultra-high-risk subset of 66 patients with relapsed/progressive disease. Effectiveness was demonstrated in the treatment of sarcomas by empirical treatment (HR 0.57, p = 0.005), which consisted mainly of orally administered cyclophosphamide, vinblastine, and celecoxib, and by sunitinib or pazopanib (HR = 0.66, p = 0.032) in biologically guided administration.
conclusionsThis study demonstrates that individualized treatment offers effective treatment options to a wide range of patients with high-risk cancers even for tumors without known high-level evidence molecular targets. We have shown that an alternative analytical approach based on the n-of-1-inspired framework is needed and applicable to demonstrate the effectiveness.
