ABSTRACT
The aim was to investigate MAGE-A4 and MAGE-A1 protein expression in high-grade endometrial cancer and determine its correlation with histologic subtype, FIGO stage, presence of vascular invasion, disease free, and overall survival. Immunohistochemical staining was performed by using 77B (MAGE-A1) and 57B (MAGE-A4) monoclonal antibodies on paraffin-embedded sections from high-grade endometrial cancers diagnosed in University Hospital Split between 1998 and 2011 (n=77). Median follow-up time for survivors was 48 mo. MAGE-A4 was found to be expressed in 33% of endometrioid type endometrial cancers grade 3 and in 27% of serous and clear cell carcinomas. MAGE-A1 was found to be expressed in 93% endometrioid endometrial cancer grade 3 and 86% of serous and clear cell carcinomas. Univariate analysis showed that positive immunohistochemical staining for MAGE-A4 was associated with decreased disease free and overall survival in patients with high-grade endometrial cancer. Multivariate analysis showed an association between MAGE-A4 overexpression and decreased disease free but not overall survival in high-grade endometrial cancer. No correlation was found between MAGE-A1 immunohistochemical expression and patient survival. There was no significant correlation between MAGE-A4 and MAGE-A1 expression and histologic subtype, FIGO stage, lymph node metastasis, muscular infiltration, and lymphovascular invasion. MAGE-A4 immunohistochemical expression is associated with decreased disease free and overall survival in patients with high-grade endometrial cancer. Our findings suggest that MAGE-A1 may be expressed in the epithelial cells of the normal endometrium. MAGE-A1 is highly expressed in high-grade endometrial cancer, with no impact on survival.
