Abstract

Background and aims: Clinically validated biomarker of pancreatic ductal adenocarcinoma (PDAC), carbohydrate antigen 19-9 (CA19-9), has limited sensitivity and specificity for early-stage disease. Circulating miRNAs in plasma associated with cancer relevant pathways were developed as early detection biomarkers.

Methods: 2083 miRNAs in 15 μl of plasma from multicenter age-matched cohorts (N = 203: healthy controls, n = 46; pancreatitis controls, n = 36; diagnosed cases: n = 121) and a prediagnostic Prostate, Lung, Colorectal, and Ovarian age- and gender-matched cohort (N = 96; controls, n = 48; prediagnosed cases, n = 48) were interrogated. A three-miRNA biomarker signature was developed for early-stage PDAC.

Results: The three-miRNA signature (let-7i-5p, miR-130a-3p and miR-221-3p) detected PDAC from healthy controls independently (area under the curve [AUC] of stage I, II, I-IV = 0.970, 0.975, 0.974) and in combination with CA19-9 (AUC of stage I, II, I-IV = 1.000, 0.992, 0.995). It also discriminated chronic pancreatitis (AUC of stage I, II, I-IV = 0.932, 0.931, 0.929), improving performance of CA19-9 alone (AUC of stage I, II, I-IV = 0.763, 0.701, 0.735) in combination (AUC of stage I, II, I-IV = 0.971, 0.943, 0.951). Blinded validation in prediagnostic Prostate, Lung, Colorectal, and Ovarian cohort revealed lead-time trajectory increase in AUC from 0.702 to 0.729 to 0.757 at twelve-, six-, and three-months before PDAC diagnosis, respectively. The signature also helped stratification of patients with different circulating tumor DNA and imaging subtypes.

Conclusion: Plasma miRNAs associated with oncogenic pathways may serve as PDAC early detection biomarkers.
