Conversely, the IC and CPS results identified B7-H4+ and PD-L1+ in HNSCC, as well aso NOM and SIN; IC (B7-H4: NOM: 13%, SIN: 69%, and HNSCC: 45%, and PD-L1: NOM: 21%, SIN: 70%, and HNSCC: 56%) and CPS (NOM: 13%, SIN: 69%, and HNSCC: 62%, and PD-L1: NOM: 21%, SIN: 73%, and HNSCC: 97%). Here, CD274 is linked to head and neck squamous cell carcinoma.
