TROY is a Promising Prognostic Biomarker in Patients with Colorectal Cancer.
Oncology Letters(2018)
Abstract
Tumor necrosis factor receptor superfamily member 19 (TROY) is involved in the Wnt/β-catenin signaling pathway and interacts with leucine-rich repeat containing G-protein-coupled receptor 5 (LGR5), which is a well-known biomarker of cancer stem cells and a prognostic marker of colorectal cancer (CRC). Because there have been no studies to evaluate the prognostic significance of TROY, we performed the present study to determine whether TROY can be a prognostic biomarker in CRC patients. We evaluated TROY expression levels in 100 CRC tissues by quantitative real-time PCR and investigated the association of TROY expression levels with clinicopathologic features. Cancer stage and TROY expression level were found to be independent prognostic factors of disease-free survival. Moreover, TROY overexpression was the sole independent prognostic factor of disease-free survival in patients with stage II and III CRC. These results suggest that analysis of TROY might help predict clinical outcome in patients with CRC. To support our findings, confirmatory studies using independent data sets are needed.
