  1. The expression of SSTR-2 was significantly relevant with the survival rate. The survival rate of patients with positive expression was higher than those with negative expression (P < 0.05*). The expressions of SSTR-2 mRNA and SSTR-3 mRNA were relevant with gender. Female positive rate was significantly higher than male (P < 0.05**). These three kinds of mRNA expression had no obvious relationships with age, TNM stage, and differentiation (P > 0.05).
