Serum metabolomics profiling in head and neck squamous cell carcinoma: a multicentre diagnostic study.
Article in EBioMedicine, 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
backgroundHead and neck squamous cell carcinoma (HNSCC) is frequently diagnosed at advanced stages, when outcomes are poor. Biomarkers for HNSCC detection remain needed.
methodsWe performed serum metabolomics profiling in 938 participants, including 457 patients with HNSCC, 451 controls, and 30 patients with oral potentially malignant disorders (OPMDs). Discovery and external validation cohorts were analysed using LC-MS/MS. Machine learning-based feature selection was used to develop an 8-metabolite diagnostic model. Disease specificity was assessed in an independent third-centre cohort. Multi-omics analyses integrating TCGA transcriptomics and spatial transcriptomics data were used to explore molecular heterogeneity. STUDY REGISTRATION: ChiCTR-BRC-17014040.
findingsSerum metabolomics profiling showed altered arginine metabolism, characterised by arginine decrease and ornithine accumulation. The 8-metabolite model achieved an internal validation AUC of 0.990, with 91.3% sensitivity and 97.1% specificity. In the multicentre external validation cohort, the model achieved an AUC of 0.901, with 91.1% sensitivity and 80.2% specificity, and maintained performance in Stage I disease, with an AUC of 0.927. In the independent disease-control cohort, the model distinguished HNSCC from healthy controls with an AUC of 0.980 and showed moderate discrimination between HNSCC and OPMDs, with an AUC of 0.710. Multi-omics analyses identified two candidate molecular subtypes with distinct immune features, prognosis, TP53 mutation status, and predicted treatment sensitivities. Spatial transcriptomics supported an inverse association between metabolic score and immune infiltration.
interpretationThis multicentre study identifies a serum metabolomics signature associated with HNSCC detection and molecular stratification. The findings support further prospective validation in clinically representative populations.
