In addition, survival association analysis between FGFR2 mRNA expression and patient RFS in each cancer type showed that among patients with LIHC or THCA, decreased FGFR2 expression was associated with short patient RFS, while among patients with BLCA or PCPG, increased FGFR2 expression was associated with short RFS (Supplementary Figure 3). This evidence concerns the gene FGFR2 and bladder transitional cell carcinoma.
