Clinical feasibility study demonstrates high-sensitivity early cancer detection using AI-driven liquid biopsy in diverse populations.

Key Points

The study aims to assess the clinical feasibility of an AI-driven liquid biopsy platform for early cancer detection using Raman spectroscopy of plasma extracellular vesicles.
Designed a multi-center feasibility study with retrospective and prospective cohorts
Isolated extracellular vesicles (EV) and analyzed Raman signal patterns
Developed an automated EV extraction and detection system
Enrolled 447 participants across five cancer types for performance evaluation
Conducted independent testing in a central lab
Achieved an AUROC of 86.6% with a sensitivity of 56.4% and specificity of 98.0%
Early-stage performance showed AUROC for lung (84.7%), breast (91.8%), colorectal (79.7%), pancreas (91.5%), and ovary (83.3%) cancers
Validated the platform’s feasibility as a prescreening tool for early-stage cancers
Integrated a secondary algorithm to identify tissue of origin for cancer-positive samples
