Fibroblast growth factors (FGFs) and their receptors (FGFRs) modulate a wide range of biological functions, especially tumor genesis. The aim of this study was to investigate the possible association of FGFR expression with the susceptibility of digestive system and reproductive system cancers in Chinese population. In total, 343 patients with digestive or reproductive system cancers were enrolled in this study. The expression levels of four highly-conserved FGFRs including FGFR1, FGFR2, FGFR3 and FGFR4 were measured by immunohistochemistry (IHC). The expression levels of FGFRs were compared between carcinoma and para-carcinoma tissues. FGFR1 expression significantly differed between carcinoma and para-carcinoma tissues in colon and gastric cancers. FGFR2 expression significantly differed between carcinoma and para-carcinoma tissues in esophageal cancer. FGFR3 expression was significantly different between carcinoma and para-carcinoma tissues in liver and gastric cancers. FGFR2 showed the highest expression probability in all the selected cancers and FGFR4 showed the lowest expression probability. FGFR1 and FGFR3 showed comparable moderate expression probabilities. Our findings have demonstrated significant differences regarding FGFR expression levels between carcinoma and para-carcinoma cells in digestive or reproductive system cancer patients. The data also implicated that FGFR2 and FGFR4 could serve as two prominent factors closely related to the susceptibility of digestive and reproductive system cancers.
