Predictive models for UC associated cancer/dysplasia were created in the setting of neoplastic and non-neoplastic mucosa.Findings: For neoplasticmucosa a five marker panel (SFRP2, SFRP4, WIF1, APC1A, APC2) was accurate in detecting pre-cancerous and invasive neoplasia (AUC=0.83; 95% CI: 0.79, 0.88), and dysplasia (AUC=0.88; (0.84, 0.91).For non-neoplastic mucosa a four marker panel (APC1A, SFRP4, SFRP5, SOX7) had modest accuracy (AUC=0.68; 95% CI: 0.62,0.73) in predicting associated bowel neoplasia through the methylation signature of distant nonneoplastic colonic mucosa.Interpretation: This multiplex methylation marker panel is accurate in the detection of ulcerative colitis associated dysplasia and neoplasia and is currently being validated in a prospective clinical trial.Funding: The ENDCAP-C study was funded by the National Institute for Health Research Efficacy and Mechanism Evaluation (EME) Programme (11/100/29).",
