VEGFA and neoplasm: The same percentage of VEGF(+) (20.7%, 23/111) and VEGF(−) (79.3%, 88/111) tumour samples was found between pOCs and rOCs, respectively, (p = 1, Fisher’s exact test, Fig. 2b, c, e, f), although no significant correlation between pOCs and rOCs VEGF IRS values could be observed (p = 0.505, Spearman coefficient 0.06).
