Expression and prognostic significance of MAGE-A11 and transcription factors (SP1,TFCP2 and ZEB1) in ESCC tissues

Abstract Objective To evaluate the clinical characteristics and prognostic significance of MAGE-A11 and transcription factors (SP1, TFCP2 and ZEB1) in patients with esophageal squamous cell carcinoma (ESCC). Methods To assess the expression of MAGE-A11 and transcription factors (SP1, TFCP2 and ZEB1) in 121 ESCC samples were respectively detected by immunohistochemical method. Results The results showed MAGE-A11 and transcription factors (SP1,TFCP2 and ZEB1) expression were associated with some clinical features in patients, such as pathological differentiation, tumor size, clinical stage, lymph node metastasis and distant metastasis. Kaplan-Meier analysis showed that patients with ESCC having high MAGE-A11 and transcription factors (SP1,TFCP2 and ZEB1) expression had a worse prognosis compared to the patients with low expression. Multivariate Cox proportional hazards regression model revealed that MAGE-A11 expression, TFCP2 expression, lymph node metastasis and distant metastasis were independently associated with ESCC patients’ survival. Conclusions High expression of MAGE-A11 and transcription factors (SP1,TFCP2 and ZEB1) in ESCC tissues suggests promoting ESCC progression and poor prognosis, co-expression of MAGE-A11 and transcription factors even worse.
