VEGFC and melanoma: Studies with melanoma patients show conflicting results; while some have shown that VEGFA and VEGFC can predict shorter overall and disease‐free survival (Boone et al., 2008; Spiric et al., 2015; Tas et al., 2006), other studies failed to prove such a correlation (Bolander et al., 2007; Vihinen et al., 2007).
