Tumor-feeding artery diameter reduction is associated with improved short-term effect of hepatic arterial infusion chemotherapy plus lenvatinib treatment

Figure 3 Anti-angiogenic activities of lenvatinib in tumor lesions. A and B: The microvessels in the tumor lesion collected before (A) and after 1 mo (B) of treatment with lenvatinib are stained with anti-CD34 antibody (× 100); C: Bars represent the microvessel density that decreased sharply after administration of lenvatinib. Data are presented as means ± SD. ^cP < 0.001 vs before treatment. MVD: Micro-vessel density.
