Antigen expression in solid tumors
Investigations of T-cell receptor (TCR) T-cell immunotherapies for solid tumors have focused on tumors with high cancer/testis antigen (CTA) expression1-2
Expression of CTAs such as New York esophageal squamous cell carcinoma 1 (NY-ESO-1), melanoma-associated antigen A4 (MAGE-A4), and preferentially expressed antigen in melanoma (PRAME) is exceptionally high and homogeneous in SyS compared with in other solid tumors.3-5
SyS=synovial sarcoma.
