FAT4 and bladder transitional cell carcinoma: The results of survival analysis indicated that increased FAT4 expression levels negatively correlated with OS, DSS, and PFS significantly of BLCA patients while positively correlated with OS of HNSC patients and KIRC patients; with DSS of LIHC patients and KIRC patients (Figure 3); with DFS of LIHC patients; with PFS of HNSC patients and KIRC patients (Figure 4), that is, FAT4 is a high-risk gene for OS, DSS, and PFS of BLCA patients.
