Abstract

There is a growing body of evidence indicating that several melanoma‑associated antigen‑A (MAGE‑A) subgroups contribute to the malignancy of head and neck cancer. The present study retrospectively analyzed the expression of all known MAGE‑A subgroups in the tumor front and center of 38 head and neck cancer patients (Union for International Cancer Control stage I or IV) by immunohistochemistry. MAGE‑A1, ‑A6, ‑A8, ‑A9 and ‑A11 were expressed at significantly higher levels at the tumor front of stage IV specimens compared with the tumor front of stage I specimens. In stage I cancer, the tumor center and front ratio (C/F ratio) for each subgroup was >1.0. In stage IV cancer, the C/F ratio was <1.0 in 9/11 subgroups. The most significant change in the expression pattern was observed for MAGE‑A11. These results indicated that there is a marked alteration and shift to the invasive front of almost all MAGE‑A subgroups, but particularly MAGE‑A11, during the progression of head and neck squamous cell carcinoma.
