Abstract: PURPOSE:To investigate the potential application of axitinib in treatment of oral mucosal melanoma (OMM). METHODS: After successful establishment of oral mucosal melanoma-bearing patient derived xenografts (PDX) model, 16 nude mice were randomly divided into control and experimental group. After oral administration of axitinib or sodium carboxymethylcellulose for 28 days, the tumors were assessed for histological and molecular features by immunochemical assay as well as growth status at least twice a week using vernier caliper. Vasculogenic mimicry was evaluated by immunochemistry and periodic acid schiff reaction (PAS) histochemical double-staining. SPSS 23.0 software package was used for statistical analysis. RESULTS: Compared to the control group, tumor volume, amount of vasculogenic mimicry and CD34-positive vessels in the axitinib group were significantly decreased after oral administration (P<0.05); meanwhile, the protein level of EphA2 and MMP-2 was significantly decreased in the axitinib group, and the expression of HIF-1a was significantly higher than the control group(P<0.05). CONCLUSIONS: Axitinib could be applied in target treatment of OMM.
