Integrated Cf-miRNA and Exosomal miRNA Signature for Early Detection of Esophageal Squamous Cell Carcinoma
Purpose
Esophageal squamous cell carcinoma (ESCC) remains a highly lethal cancer worldwide, largely due to late diagnosis. Current screening methods such as upper endoscopy are invasive, operator-dependent, and limited in their ability to detect early-stage lesions. To address this clinical need, the SYNERGY study seeks to develop a non-invasive, blood-based biomarker assay that integrates cell-free microRNAs (cf-miRNAs) and exosomal microRNAs (exo-miRNAs) to detect ESCC at an early and potentially curable stage. This multicenter translational study includes discovery, training, and validation phases using preoperative plasma or serum samples. By combining the tumor specificity of exosomal miRNAs with the systemic sensitivity of cf-miRNAs, SYNERGY aims to construct a robust diagnostic model with high sensitivity and specificity for early ESCC detection.

Detailed Description
Esophageal cancer is the 11th most common cancer globally and the 7th leading cause of cancer-related death, with an estimated 511,000 new cases and 445,000 deaths annually. ESCC accounts for the majority of cases worldwide. Despite advances in endoscopy and therapy, outcomes for advanced ESCC remain poor, highlighting the pressing need for sensitive, minimally invasive early detection strategies. Exosomal miRNAs (exo-miRNAs) are selectively released by tumor cells and remain stable in circulation, enabling reliable detection of tumor-specific signals. Cell-free miRNAs (cf-miRNAs) circulate broadly and can reflect overall tumor burden, metastatic spread, and microenvironmental changes. Previous ESCC biomarker studies were limited by small validation cohorts and reliance on tissue-based public datasets that do not fully capture circulating biomarker patterns. The SYNERGY study addresses these limitations through comprehensive discovery analysis and multi-cohort blood-based validation.
