Objective To investigate the expressions and significance of chemokines factor receptors 4 (CXCR4) and chemokines factor receptors 7 (CXCR7) in gastric cancer tissues. Methods Sixty-five patients with gastric cancer who treated in our hospital from January 2011 to June 2013 were retrospectively collected as gastric cancer group, and 20 patients with gastric ulcer were retrospectively collected as control group at the same time. The expressions of CXCR4 and CXCR7 in gastric cancer tissues and normal gastric tissues were measured by immunohistochemistry, and then the relation-ship among expressions of CXCR4/CXCR7 in gastric cancer tissues and clinicopathological features of patients with gastric cancer was explored, as well as its effect on survival. Results Positive expression rates of CXCR4 and CXCR7 were identi-fied in 80.00% (52/65) and 84.62% (55/65) of the gastric cancer group, and 5.00% (1/20) and 10.00% (2/20) in control group respectively, and the positive expression rates of CXCR4 and CXCR7 in gastric cancer group were significantly higher than those of control group respectively (χ2=36.65, P<0.01; χ2=38.55, P<0.01). The positive expression rate of CXCR4 in gastric cancer tissues was related with degree of differentiation, T staging, and TNM staging (P<0.05), positive expression rate of CXCR4 in patients with poor differentiation, T3-4 staging, and TNM Ⅲ-Ⅳ staging were higher than corresponding patients with moderate/high degree of differentiation, T1-2 staging, and TNM Ⅰ-Ⅱ staging. The positive expression rate of CXCR7 in gastric cancer tissues was related with degree of differentiation, T staging, and N staging (P<0.05), positive expression rate of CXCR7 in patients with poor differentiation, T3-4 staging, and N1-3 staging were higher than corrsponding patients with moderate/high degree of differentiation, T1-2 staging, and N0 staging. The survival situation was worse in patients with positive expression of CXCR4 and CXCR7 than corresponding patients with negative expression (P=0.01, P=0.01) respectively. Conclusions CXCR4 and CXCR7 are related to gastric cancer genesis and development. Furthermore, the expressions of CXCR4 and CXCR7 could be used as markers to predict prognosis of gastric cancer. The regulation of CXCR4/chemokine ligand 12 (CXCL12) axis and CXCR7/CXCL12 axis may provide a new targeted therapy for patients with gastric cancer.
