Plasma miRNA can detect colorectal cancer, but how early?

ABSTRACT: Colorectal cancer (CRC) is a major cause of deaths worldwide but has a good prognosis if detected early. The need for efficient, preferable non- or minimally invasive, inexpensive screening tools is therefore critical. We analyzed 12 miRNAs in pre- and postdiagnostic plasma samples to evaluate their potential as CRC screening markers. We used a unique study design with two overlapping cohorts, allowing analysis of pre- and postdiagnostic samples from 58 patients with CRC and matched healthy controls. Plasma concentrations of miR-15b, -16, -18a, -19a, 21, -22, -25, -26a, -29c, -142-5p, -150, and -192 were measured by semi-quantitative real-time PCR. Concentrations of miR-18a, -21, -22, and -25 in plasma from patients with CRC were significantly altered compared to healthy controls. Combined
