Introduction: Methylsulfonic
apatinib (hereinafter referred to as Apatinib) is a small-molecule angiogenesis
inhibitor highly and selectively targeted to vascular endothelial growth factor
receptor-2. At present, a series of basic and clinical studies have confirmed
that Apatinib monotherapy can inhibit the growth of different carcinomas. Our
experiment aimed to determine whether there is a synergistic effect between the
combination of the traditional cytotoxic chemotherapy drugs paclitaxel (TAX),
oxaliplatin (L-OHP), 5-fluorouracil (5-FU), and Apatinib.
Materials and methods: We evaluated the combined effect using cytological experiments and a fluorescence imaging xenograft model. In vitro, the inhibition of cell proliferation increased notably when Apatinib was combined with TAX, L-OHP, and 5-FU. Then, for the mechanistic research, we selected the optimal dose of drugs that also had a synergistic effect. Apatinib combined with the aforementioned drugs, especially the combination of Apatinib and 5-FU, decreased the invasion and migration ability of the cells and increased the apoptosis ratio; expression of the anti-apoptotic protein Bcl-2 significantly decreased, and expression of the pro-apoptotic protein Bax increased. In vivo, when Apatinib was combined with TAX, L-OHP, and 5-FU, the volume of the xenograft model was significantly inhibited, the strength of the green fluorescence was weakened and the microvessel density decreased.
Results: The combination of Apatinib with TAX and 5-FU was synergistic (coefficient of drug interaction <1); the combination effect of Apatinib and L-OHP was only additive, with a shorter associated survival time.
Conclusion: The combination of Apatinib and classical chemotherapy drugs may be an optimal choice for gastric cancer treatment.
