VEGFA and neoplasm: As a result (Fig. 4b), the average tumor weight of SW620 cells in the presence of both anti-VEGF mAb and anti-EGFR mAb was 0.198 ± 0.022 g, which was significantly lower (P < 0.05) than that of mice inoculated with anti-VEGF mAb (0.412 ± 0.036 g), anti-EGFR mAb (0.440 ± 0.038 g), and negative control group (0.952 ± 0.056 g).
