Abstract

Bladder cancer is a common urinary malignancy and a prevalent cause of cancer-related death. Current therapies of early stage non-muscle-invasive bladder cancer (NMIBC) are frequently associated with undesirable toxicities and recurrence. Active antigen-specific immunotherapy may provide a valid therapeutic option for patients with NMIBC. Cancer-testis antigens (CTA) expressed in various tumour types and in a limited range of healthy tissues may represent potential targets for specific immunotherapy. MAGE-A10 is probably the most immunogenic antigen of the MAGE-A family. We evaluated the expression of MAGE-A10 in NMIBC. Seventy-nine patients undergoing surgical treatment for NMIBC were enrolled in the study. MAGE-A10 gene expression was assessed by quantitative real-time polymerase chain reaction. Immunohistochemistry was performed on paraffin-embedded sections. MAGE-A10 gene was specifically expressed in one-third of NMIBC (n = 24: 32.43%). Gene expression was correlated with high tumour grade. MAGE-A10 protein was exclusively detectable in nuclei of tumour cells. More importantly, MAGE-A10 protein was also more frequently detectable in high-grade tumours (p = 0.0001) and in stage T1 tumours invading subepithelial tissue or lamina propria (p = 0.01). A strong correlation between MAGE-A10 staining score and tumour grade and stage could accordingly be observed. These data indicate that MAGE-A10 expression is a feature of aggressive NMIBC and might be used as a novel target for specific immunotherapy of these cancers.
