VEGFR-2 immunohistochemical examination image. (a) Normal liver parenchyma shows nonspecific staining. (b) VX2 tumor before microwave ablation shows positive staining. (c, d) Residual tumor (RT) and inflammatory reaction band (IRB) coexist after ablation, RT shows positive staining, IRB shows weak positive staining, and the necrosis zone (NZ) shows negative staining.
