Integrative analyses of metastatic cancer transcriptome reveal clinically distinct cellular States and ecosystems.
Article in Scientific reports, 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
Determining the diverse cellular states and their organization into cellular ecosystems that make up metastatic tumor is vital for elucidating the biological and prognostic diversity of cancer. However, large-scale studies profiling the clinical relevance of these cellular states and ecotypes are still lacking in metastatic cancers. In this study, we used EcoTyper, a machine learning framework, to comprehensively analyze transcriptomes from 2822 metastatic cancer patient samples covering 25 cancer types, enabling characterization of the fundamental cellular states and tumor ecosystems integral to metastatic cancer. We identified 45 distinct cellular states across 12 cell types and validated their robustness in validation cohorts. We observed that they differed in functional and prognostic associations. Survival analysis revealed that the clinically relevant cellular states, highlighting their promise as predictors of clinical outcomes. Functional enrichment analysis exhibited that the marker genes of cellular states were significantly enriched in cancer hallmark and immune-related pathways. In addition, our analysis identified five ecotypes associated with different clinical outcomes. Transcription factor enrichment analysis revealed key transcription factors (i.e. SPIB, SRF, and NR1D1) that were significantly associated with patient clinical outcomes. In conclusion, this study provided a high-resolution landscape of cellular states and ecosystems in metastatic tumors, offering new potential targets for the development of cancer treatment strategies and prognostic assessment.
