KDR and neoplasm: No statistically significant correlation was detected between VEGF-A, VEGFR-1 or VEGFR-2 expression and age at diagnosis (r = 0.13, p = 0.50; r = −0.09, p = 0.62 and r = −0.11, p = 0.55, respectively) or tumor size (r = 0.29, p = 0.14; r = 0.16, p = 0.42 and r = 0.13, p = 0.52, respectively).
