We analyzed MAGE-A3 expression of sarcoma subtypes available in the Cancer Genome Atlas and Cancer Cell Line Encyclopedia and show that undifferentiated pleomorphic sarcoma/myxofibrosarcoma (UPS/MFS) expresses this potential target gene.
The National Cancer Database was queried for women who underwent NAC and surgery for unilateral clinical stage I to III (cT1-3) invasive breast cancer from 2010 to 2013.
Analysis of cancer/testis antigen expression and CD8 T-cell abundance suggests that MAGEA3 is a potential immune target in melanoma, but not in non-small cell lung cancer, and implicates SPAG5 as an alternative cancer vaccine target in multiple cancers.
Cancer-germline gene MAGE-3 encodes for an antigenic nonapeptide (MAGE-3(168-176) peptide) that is recognized by CTLs on human leukocyte antigen (HLA)-A1 and HLA-B35 molecules.
Although this study confirmed the relatively higher expression of the MAGE gene family in human advanced gastric carcinomas, it might suggest that simultaneous expression of MAGE-3 and HLA-A2 genes does not necessarily imply the induction of cancer cell apoptosis by CTL.
Therefore, these findings seem to indicate that HLA-A2-restricted MAGE-3 peptide may be potentially useful for specific immunotherapy in cancer patients.
