Correlation between immunohistochemical markers and different clinical parameters. (A) Positive correlation between VEGFR-2 immunoexpression and tumor grade (p = 0.001; Spearman R = 0.6071). (B) Absence of correlation between PDGFR expression and tumor grade (p = 0.0692; Spearman R = 0.3620). (C) Positive correlation between VEGFR-2 and PDGFR expression (p = 0.01; Spearman R = 0.4959). (D) Positive correlation between PDGFR expression and microvascular density (p = 0.0102; Spearman R = 0.4946).
