Numerous tumor antigens have so far been identified from various tumors using the serological identification of antigens by recombinant expression cloning (SEREX) method. Among them, cancer/testis (CT) antigens are considered promising target molecules for immunotherapy for patients with various cancers. We performed several SEREX analyses of various cancers to identify CT antigens, including gastric adenocarcinoma, lung adenocarcinoma, and colon cancer, and consequently identified additional CT antigens, such as XAGE-1, CCDC62-2, GKAP1, and TEKT5. However, although SEREX analysis of squamous cell carcinoma of the head and neck (HNSCC) has been performed several times, only a few CT or HNSCC specific antigens have yet been isolated. Compared with other tumors, a small number of studies have been reported on the antigen proteins specific to HNSCC. We here reported the expression of selected CT antigens and their immunogenicity in patients with HNSCC. The results obtained suggested that CCDC62-2, GKAP1, and TEKT5 are immunogenic in HNSCC and also demonstrated their potencies as diagnostic markers for patients with HNSCC in combination with other CT antigens such as NY-ESO-1, MAGE-A3, and MAGE-A4.
