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 0.024 HR 2.2 95 CI 1.1-4.4 and the co-expressions of FGF2 PDGF-B overall P 0.007 intermediate P 0.013 HR 3.6 95 CI 1.3-9.7 high P 0.002 HR 6.0 95 CI 2.0-18.1 and FGF2 VEGFR-3 overall P 0.050 intermediate P 0.058 HR 2.0 95 CI 0.98-4.1 high P 0.028 HR 2.6 95 CI 1.1-6.0 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 . .
