Abstract:Objective: To Observe the changes of ERCC1 and SLC7A11 expression in esophageal cancer tissue, and to explore the role of ERCC1 and SLC7A11 in esophageal cancer chemotherapy. Methods: The expression levels of ERCC1 and SLC7A11 in 92 cases of esophageal cancer tissue (experimental group) and 36 cases of normal esophageal mucosa tissue (control group) were detected by SP immunohistochemical method, and the relationship between the relative transcript levels and clinicopathological characteristics of patients with esophageal cancer was analyzed. Results: The positive rates of ERCC1 and SLC7A11 expression in esophageal cancer group were higher than those in control group (P<0.01). The high expression of ERCC1 was correlated with the clinical stages, differentiation degrees and lymph node metastasis of esophageal cancer (P<0.05), but not with gender and age (P>0.05).The high expression of SLC7A11 was correlated with the clinical stages, lymph node metastasis, and differentiation degrees of esophageal cancer (P<0.05), but not with gender and age (P>0.05).Pearson correlation analysis showed that ERCC1 expression level was positively correlated with SLC7A11 expression level.Kaplan-Meier analysis showed that the recurrence rate of esophageal cancer patients with ERCC1 (+)/SLC7A11 (+) high expression was also higher than that of patients with negative ERCC1/ SLC7A11 expression at 3 years after treatment. The difference was statistically significant (P<0.05). The overall survival rate at 3 years was lower than that of patients with negative expression (P < 0.05).Among 81 patients receiving neoadjuvant chemotherapy, there were 59 patients in the sensitive group and 22 patients in the drug resistant group. The positive expression rate of ERCC1 was significantly different between the two groups (P<0.01). The positive expression rate of SLC7A11 was significantly different between the two groups (P<0.05). Conclusion: The expression levels of ERCC1 and SLC7A1,to some extent, are of a certain guiding effect on preoperative neoadjuvant chemotherapy in patients with esophageal cancer, and the efficacy of neoadjuvant chemotherapy in patients with ERCC1 (+)/SLC7A11 (+) high expression is poor.
