The expression and prognostic value of SOX2, β-catenin and survivin in esophageal squamous cell carcinoma

Aim: We mainly explored the effect of SOX2, beta-catenin and survivin on prognosis in esophageal squamous cell carcinoma. Materials & methods: Immunohistochemistry was used to examine the expression of SOX2, beta-catenin and survivin. chi(2) test was used to analyze the relationship between proteins and clinicopathological parameters. Survival analysis was used to investigate the effect of three proteins on prognosis. Results: SOX2 was related to lymph node metastasis (p = 0.004) and vascular invasion (p = 0.041). beta-catenin was associated with depth of invasion (p = 0.014), lymph node metastasis (p = 0.032) and postoperative chemoradiotherapy (p < 0.001). Survivin was related to gender (p = 0.022) and nerve invasion (p = 0.014). There was a positive correlation between SOX2 and beta-catenin. Patients with SOX2 and beta-catenin overexpression had poor prognosis. Survivin-positive patients who received postoperative chemoradiotherapy had a short time. Conclusion: SOX2, beta-catenin and survivin can be used as prognostic markers of esophageal squamous cell carcinoma.
