For example in sarcomas targeting ERBB2/HER2 [101], renal cell cancer targeting carbonic anhydrase IX (CAIX) [102], non-small cell lung cancer and cholangiocarcinoma targeting epidermal growth factor (EGFR) [103], and neuroblastoma targeting GD2 [104] and other solid tumors (targeting shared antigens including mesothelin and CEA) [105]. Here, CA9 is linked to sarcoma.
