Abstract

The melanoma-associated antigens A1, -A9, -A11 (MAGE-A1, -A9, -A11) are relatively tumor-specific in laryngeal squamous cell carcinoma (LSCC), and could be ideal antigens for LSCC immunotherapy. In addition, MAGE-A9 probably is a poor prognostic marker for LSCC patients. The MAGE-A family belongs to Cancer/testis antigens (CTA). However, the expression pattern of MAGE-A1, MAGE-A9, and MAGE-A11 in LSCC is still unclear. This study aims to evaluate the expression and possible prognostic role of MAGE-A1, MAGE-A9, and MAGE-A11 in LSCC patients. The expression of MAGE-A1, MAGE-A9, and MAGE-A11 in LSCC specimens was investigated by immunohistochemistry, and the association of their expression and the clinical parameters and the survival of LSCC patients were analyzed by chi-square test, Kaplan-Meier survival and Cox regression analysis. The expression rates of MAGE-A1, MAGE-A9, and MAGE-A11 in LSCC were 54.7%, 46.2%, and 51.9%, respectively. The expression of MAGE-A1, MAGE-A9, and MAGE-A11 in LSCC was correlated with clinical stage, lymph node metastasis, and tumor size. The overall survival of LSCC patients with positive MAGE-A1, MAGE-A9, or MAGE-A11 expression was lower than the patients without MAGE-A1, MAGE-A9, or MAGE-A11 expres...Continue Reading
