The expression of FGF-2 in human bladder cancer has been linked to aggressive behavior and poor prognosis.3,5,26,27 Using the UCSC Xena Genome Browser, we generated Kaplan–Meier survival curves for tumors based on FGF-2 expression, which confirmed this finding in a provisional set of 407 primary muscle invasive bladder carcinomas in the cancer genome atlas (TCGA) database (Figure 1a). Here, FGF2 is linked to urinary bladder carcinoma.
