Early cancer detection or prevention

Systematic verification of saliva-based biosignatures for oral cancer via targeted metabolomics.

A four-molecule saliva test reliably detects oral cancer and tracks risk, offering non-invasive screening for high-risk patients.

Targeted LC-MRM-MS metabolomics in 299 subjects (98 healthy, 103 OPMD, 98 OSCC) identified a four-metabolite salivary panel achieving AUC=0.91 for distinguishing OSCC from healthy controls, with cadaverine and N-acetylcadaverine progressively elevated from OPMD through OSCC stages. The findings support polyamine-associated metabolic reprogramming as a validated hallmark of oral malignant transformation and establish non-invasive salivary metabolomics as a clinically accessible tool for OSCC detection and risk stratification.

Why it surfaced

Well-powered saliva-based metabolomics panel (n=299, AUC=0.91) with progressive disease-stage correlation addresses a significant clinical gap for non-invasive accessible OSCC screening; polyamine pathway provides a mechanistic basis for further biomarker development.
