Additionally, the research performed by Penco-Campillo et al. is concordant with that of Song et al. In their study of medulloblastoma, they revealed that all the principal tumor subgroups (Wingless, Sonic Hedgehog, Group 3, Group 4) experienced a decrease in tumor growth by VEGF-C (Penco-Campillo et al., 2020) as increased lymphangiogenesis led to a subsequent increase in lymphatic drainage. This evidence concerns the gene VEGFC and neoplasm.
