Abstract: Esophageal cancer is a common type of cancer in the People’s Republic of China. Many genes have been reported to be linked with it. Melanoma antigen gene family A (MAGEA) genes are frequently highly expressed in various types of carcinoma. However, the specific role of MAGEA gene expression in esophageal squamous cell carcinoma (ESCC) still remains unclear. MAGEA4 is a member of MAGEA genes. We aimed to investigate the expression and prognosis of MAGEA4 expression in ESCC. MAGEA4 messenger RNA expression levels of 120 pairs of tumor and nontumor tissues of patients with ESCC were measured by quantitative real-time polymerase chain reaction. The results showed that MAGEA4 messenger RNA was significantly elevated in tumor tissues of patients with ESCC compared to nontumor ones. In addition, overexpression of MAGEA4 messenger RNA was significantly correlated with poorer overall survival (P=0.018) in early stage of patients with ESCC (I–IIA). In conclusion, MAGEA4 played an important role in the early stage of ESCC and overexpression of MAGEA4 was expected to become a potential prognostic marker for patients with early stage of ESCC.
