Abstract

Background:

Annexin-A7 (ANXA7) exhibits biological and genetic properties expected of a tumor suppressor gene and may play a role in cancer progression. However, the ANXA7 expression in different histological subtypes of gastric adenocarcinomas and its correlation with invasive potentials has not been elucidated.

Methods:

Immunohistochemical staining of ANXA7 for 84 primary gastric adenocarcinomas was performed, and data was correlated with clinicopathological parameters of patients.

Results:

The ANXA7 expression was well correlated with the grade of differentiation of primary tumors. Its expression was detected in 100% (8/8), 64.9% (24/37), 66.7% (2/3), 31.9% (13/31), 0% (0/3), and 0% (0/2) of well-differentiated tubular, moderately-differentiated tubular, papillary, poorly differentiated, signet-ring cell, and mucinous adenocarcinoma, respectively. According to the Lauren's classification, the ANXA7 expression was higher in intestinal type than in diffuse type tumor (71.9% vs. 6.1%, P = 0.003). The loss of expression of ANXA7 expression was significantly related to distant metastasis (P = 0.04). However, there were no significant associations between the ANXA7 expression and survival of cancer patients (P = 0.159).

Conclusions:

A striking correlation between ANXA7 expression and cell differentiation of gastric cancer was observed. The loss of expression of ANXA7 is associated with distant metastasis.
