Abstract
Methods: We performed miRNA candidate discovery using three ESCC tissue miRNA datasets (n =108, 238, and 216) and the candidate miRNAs were confrmed in tissue specimens (n =64) by qRT-PCR. Using a serum training cohort (n =408), we conducted multivariate logistic regression analysis to develop an ESCC circulating miRNA signature and the signature was subsequently validated in two independent retrospective and two prospective cohorts.
Results: We identifed eighteen initial miRNA candidates from three miRNA expression datasets (n =108, 238, and 216) and subsequently validated their expression in ESCC tissues. We thereafter confrmed the overexpression of 8 miRNAs (miR-103, miR-106b, miR-151, miR-17, miR-181a, miR-21, miR-25, and miR-93) in serum specimens. Using a serum training cohort, we developed a circulating miRNA signature (AUC:0.83 [95%CI:0.79–0.87]) and the diagnostic performance of the miRNA signature was confrmed in two independent validation cohorts (n =126, AUC:0.80 [95%CI:0.69–0.91]; and n =165, AUC:0.89 [95%CI:0.83–0.94]). Finally, we demonstrated the diagnostic performance of the 8-miRNA signature in two prospective cohorts (n =185, AUC:0.92, [95%CI:0.87–0.96]); and (n =188, AUC:0.93, [95%CI:0.88–0.97]). Importantly, the 8-miRNA signature was superior to current clinical serological markers in discriminating early stage ESCC patients from healthy controls (p <0.001).
Conclusions: We have developed a novel and robust circulating miRNA-based signature for early detection of ESCC, which was successfully validated in multiple retrospective and prospective multinational, multicenter cohorts.
