Expression and clinical significance of ADAMTS5 in human gastric cancer / 实用医学杂志

ABSTRACT

Objective To investigate the expression status of A Disintegrin and Metalloproteinase with Thrombospondin motifs 5(ADAMTS5 )and its clinical significance in primary human gastric cancer(GC). Meth-ods ADAMTS5 protein expression in 176 GC tissues and 24 adjacent normal tissues was detected by immunohisto-chemistry(IHC),and its correlation to clinicopathological features and prognosis in patients with gastric cancer was analyzed. Results ADAMTS5 expression was lower in GC tissues compared with adjacent normal tissues. Moreover,low expression of ADAMTS5 was associated with gender,histologic type,degree of differentiation,M stage,TNM stage and vascular invasion,which was also an independent indicator for poor prognosis for GC pa-tients. Conclusions ADAMTS5 expression was lower in GC tissues,which was associated with clinicopathological features and prognosis,suggesting a novel potential prognostic indicator and therapeutic target in GC.
