PRAME and neoplasm: Sarcomas consist of more than one hundred diverse bone and soft tissue cancers that are rare and heterogeneous, accounting for approximately 1% of adult tumours and 15% of paediatric cancers.88 The antigen PRAME is highly expressed in numerous types of sarcomas, such as synovial sarcoma, liposarcomas and myxoid/round cell liposarcoma.89, 90, 91, 92 Moreover, myxoid liposarcomas have higher levels of PRAME and NY‐ESO‐1 than other liposarcomas at both the transcriptional and translational levels.
