For instance, in estrogen receptor–negative ductal carcinoma in situ, cancer/testis antigens are expressed in conjunction with HER2 positivity and a marked stromal immune response, suggesting that CT47A9 may similarly contribute to the tumor phenotype observed in high‐risk breast lesions."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n \n "}, {"type": "p", "children": [{"type": "t", "text": "\n In prostate cancer, high‐throughput antigen microarray studies have identified several cancer/testis antigens as potential diagnostic and therapeutic biomarkers.
