Elevated Microsatellite Alterations at Selected Tetranucleotide Repeats (EMAST) and Microsatellite Instability in Patients with Colorectal Cancer and Its Clinical Features

摘要

Purpose: Recently, a different type of microsatellite instability (MSI) instability designated 'elevated microsatellite alterations at selected tetranucleotide repeats' (EMAST) has been reported in several neoplasms, but its clinical implications remain unclear. We aimed to determine the relationships among EMAST, MSI and clinicopathologic characteristics, including oncologic outcomes, in colorectal cancer (CRC).
