The aim of the present study was to explore the expression of the cancer testis antigens New York-esophageal squamous cell carcinoma (NY-ESO)-1 and melanoma-associated antigen (MAGE)-A4 in high-grade soft-tissue sarcoma and to evaluate their association with the standard clinical-pathological features of surgically treated high-grade sarcoma patients.
Melanoma-associated antigen-A (MAGE-A) and New York esophageal squamous cell cancer-1 (NY-ESO-1) are 2 cancer testis antigens (CTA) demonstrating potential for use in targeted immunotherapy.
The cancer testis antigen (CTA), melanoma-associated antigen A3/6 (MAGE-A3/6), is expressed in human cancers of different histologic types, to variable extents, and is an important target for immunotherapy.
The expression of CT antigens (melanoma-associated antigen gene [MAGE]-A4 and KK-LC-1) and the EGFR-activating mutation (L858R point mutation in exon 21 and inframe deletion in exon 19) was evaluated by using polymerase chain reaction amplification.
In this study, a single-chain T-cell receptor (scTCR) directed against the CT antigen melanoma-associated antigen (MAGE)-A1 in complex with the HLA class I molecule of haplotype HLA-A1 is fused with the C terminus of the adenovirus minor capsid protein IX.
