HLA-G and PD-L1 exhibited consistent high-expression in pancreatic cancer [64], breast cancer [194], papillary thyroid cancer [195], kidney cancer [12, 196, 197], colorectal cancer [102], oral osteosarcomas [198], and intraoral mucoepidermoid carcinoma [199]. This evidence concerns the gene HLA-G and thyroid gland papillary carcinoma.
