Study on the relationship between the expressions of CyPJ,ERp29 and CSN5 in patients with gastric cancer and prognostic survival

Objective To analyze the relationship between the expression of CyPJ,ERp29 and CSN5 in patients with gastric cancer and the prognosis and survival. Method The data of 115 patients with gastric cancer admitted to our hospital from June 2015 to June 2017 were retrospectively analyzed,and tumor tissue(cancer tissue group)and normal gastric mucosal tissue adjacent to the tumor(paracancerous normaltissue group)were collected. The expressions of CyPJ,ERp29 and CSN5 in different tissues were compared. The correlation between CyPJ,ERp29 and CSN5 and the pathological parameters of patients with gastric cancer was analyzed. Kaplan-Meier survival analysis was used to analyze the effect of CyPJ,ERp29 and CSN5 expression on the prognosis survival of patients with gastric cancer and multivariate Logistic regression was used to analyze the risk factors affecting the prognosis and survival. Result The positive expression rates of CyPJ and CSN5 in the gastric cancer tissue group were significantly higher than those in the paracancerous normal tissue group,and the positive expression rate of ERp29 was lower than that in the paracancerous normal tissue group. The difference was statistically significant(P<0.05). There was no significant correlation between age,gender,serosal-infiltration and the expression of CyPJ,ERp29 and CSN5 in gastric cancer patients(P>0.05),but the clinical stage,depth of invasion,and lymph node metastasis were positively correlated with the expression of CyPJ and CSN5,and the degree of tissue differentiation was negatively correlated with the expression of CyPJ and CSN5.ERp29 was positively correlated with the degree of tissue differentiation,and negatively correlated with clinical stage,depth of invasion,and lymph node metastasis(P<0.05). At the end of the follow-up,79 patients with gastric cancer survived,36 died,and the mortality rate was 31.30%. Survival analysis showed that patients with CyPJ,CSN5(expression negative)and ERp29(expression positive)had longer survival times,and Keplanmeier survival curves were significantly different(P<0.05). Moderate to low differentiation of tissues,TNM staging:stage Ⅲ+Ⅳ,lymph node metastasis,negative expression of ERp29,positive expression of CyPJ and CSN5 were independent risk factors affecting the prognosis and survival of patients with gastric cancer(P<0.05). Conclusion CyPJ,ERp29 and CSN5 are abnormally expressed in gastric cancer tissues. Their expression levels are related to the clinicopathological characteristics and prognosis of the tumor.
