HLA-G and bladder transitional cell carcinoma: The results showed that patients with higher HLA-G expression in the BLCA (P=3.4E-05), KIRC (P=0.029), KIRP (P=0.021), LIHC (P=0.014), and LUAD (P=0.039) groups were had significantly longer RFS, whereas higher HLA-G in the pancreatic ductal adenocarcinoma (PDAC) (P=0.011) group was significantly associated with shorter RFS.
