Comparison of an Established Simple Office-Based Immunological FOBT With Fecal Tumor Pyruvate Kinase Type M2 (M2-PK) for Colorectal Cancer Screening: Prospective Multicenter Study

Abstract

This office-based IFOBT was found to have significantly higher specificity, PPV, and positive LR as compared with M2-PK. IFOBT proved to be a convenient, noncumbersome, quick, and cheap tool in patients with above-average risk for detection of CRN.
