Fibroblast growth factor 2 FGF2 and fibroblast growth factor receptor-1 FGFR-1 in close interplay with platelet-derived growth factor-B PDGF-B and vascular endothelial growth factor receptor-3 VEGFR-3 are strongly involved in angiogenesis. This study investigates the prognostic impact of FGF2 and FGFR-1 and explores the impact of their co-expression with PDGF-B and VEGFR-3 in widely resected tumors from non-GIST STS patients. Methods Tumor samples from 108 non-GIST STS patients were obtained and tissue microarrays were constructed for each specimen. Immunohistochemistry was used to evaluate the expressions of FGF-2 FGFR-1 PDGF-B and VEGFR-3. Results In the multivariate analysis high expression of FGF2 P HR 95 CI and the co-expressions of FGF2 PDGF-B overall P intermediate P HR 95 CI high P HR 95 CI and FGF2 VEGFR-3 overall P intermediate P HR 95 CI high P HR 95 CI were significant independent prognostic indicators of poor disease-specific survival. Conclusion FGF2 alone or in co-expression with PDGF-B and VEGFR-3 is a significant independent negative prognosticator in widely resected non-GIST STS patients. Introduction Soft-tissue sarcomas STSs constitute a group of tumors of mesenchymal lineage comprising over 50 histological entities 1 . .
