Abstract
ADAMTS-2 is a member of the ADAMTS family and is a procollagen N-proteinase. The objective of our research is to explore the prognostic significance of ADAMTS-2 in gastric carcinoma. A total of 655 samples with full clinicopathological data were investigated in this study. Tissue microarray immunohistochemistry analysis was used to analyze the relationship between clinicopathological characteristics and ADAMTS-2 expression. Oncomine and Kaplan-Meier plotters were performed for the relationship analysis between prognosis and ADAMTS-2 expression in patients with gastric cancer. Compared with that of normal tissues, the ADAMTS-2 protein expression was remarkably higher in gastric cancer cells and fibroblast cells. The results of univariate analysis indicated that the expression of ADAMTS-2 in tumor cells and fibroblast cells, Laurén classification, TNM grade, and carcinoembryonic antigen level in gastric cancer were all correlated with overall survival. The results of multivariate analysis indicated that the high expression of ADAMTS-2 in gastric cancer cells and fibroblast cells both were independent prognostic factors. Therefore, ADAMTS-2 may be a potential biomarker for assessing the prognosis of gastric carcinoma.
