Abstract
Background: STING is an innate immune sensor for cytosolic DNA. The activation of STING signaling is indispensable in Type I interferon response and the evocation of anticancer immune response by CD8+ T-cells. The aim of this study is to characterize intratumoral STING expression pattern and its clinical implication in colorectal cancer (CRC). Methods: We analyzed STING and CD8 expression in 225 CRC patients who underwent surgical resection. Clinicopathologic variables and survival outcomes were analyzed according to STING expression level. Results: Distinct STING expression was observed in tumor specimens of CRCs. Patients with higher STING expression seemed to have early stage cancer (P = 0.001) with increased intratumoral CD8+ T-cell infiltration (P Citation Format: Hongjae Chon, Chan Kim.
