Prognostic Value of Autophagy, Microsatellite Instability, and KRAS Mutations in Colorectal Cancer.

ABSTRACT: Introduction: Autophagy plays pivotal role in various tumors, including colorectal cancer (CRC). Microsatellite instability (MSI) and KRAS mutations are also involved in response to the adjuvant therapy of CRC. We aimed to investigate the relationships among autophagy, KRAS mutations, MSI, clinicopathological parameters, and prognosis in CRC patients. Methods and Results: We tested 200 CRC tumors for autophagy-related protein expression (Beclin 1 and LC3), MSI status, and KRAS mutations. Results: Expression of Beclin 1 and LC3 was higher in CRC, with Beclin 1 significantly correlating with the depth of invasion, whereas LC3 was not associated with clinicopathological parameters. Patients expressing the LC3 proteins experienced a shorter overall sur
