Molecular profiling and access to treatment for rare cancers in Europe.
Article in Nature communications, 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
Arcagen is a clinical study proposing a comprehensive analysis of molecular and clinical characteristics of rare adult solid cancers (11 domains: sarcomas, gynecology, uro-genital, GI, NET, head and neck, thoracic, skin and eyes, CNS and CUP) across Europe, utilizing the EORTC-SPECTA platform with the EURACAN ERN. This study enrolled 1235 advanced stage patients. 893 were evaluable for molecular profiling toward a potential access to personalized therapy.In the 11 different domains, 69.4% (620/893) of patients had actionable mutations, among whom 93 (15% of 620 patients with currently actionable alterations) received targeted- or immune (IO)-therapies. The median overall survival of the patient population without treatment adaptation, with switch to targeted therapy, or immunotherapy was 1.1, 3.3 years, and not reached, respectively.Across Europe, high prevalence and diversity of molecular alterations for rare solid tumors were observed as well as significant disparities regarding access to personalized medicine approaches.
