FGFR3 and esophageal squamous cell carcinoma: In addition, survival correlation analysis between mRNA expression of FGFR3 and patient RFS across different tumors exhibited that increased mRNA expression of FGFR3 was correlated with poor RFS in ESCC, KIRP, and UCEC, while high mRNA expression of FGFR3 was correlated with better RFS in HNSC, LUSC, and THCA (Supplementary Figure 5).
