Hepatocellular carcinoma (HCC) is the third-leading cause of cancer-related deaths with 750,000 newly diagnosed cases each year. Surgery, radiotherapy, and chemotherapy constitute the main treatment modalities for HCC, but liver cirrhosis and damage often occur. Molecular targeted drugs have been recently developed to treat HCC. Vascular endothelial growth factor (VEGF)/VEGF receptor (VEGFR) autocrine signaling is closely related to the growth, progression, and metastasis of HCC, making the VEGF/VEGFR axis an ideal target for the development of molecular targeted agents. Here, we report the effects of the novel anti-VEGF humanized monoclonal antibody BD0801 on the growth of HCC cells in vitro and in vivo as well as the underlying mechanisms. BD0801 significantly inhibited the proliferation of HepG2, SMMC-7721, and Bel7402 cells in vitro, accompanied with an induction of apoptosis and cell cycle arrest at the G1 phase. BD0801 potently suppressed AKT, Erk1/2, and retinoblastoma (Rb) phosphorylation, while increasing p21 and decreasing cyclin D1 protein levels. BD0801 significantly inhibited growth in mouse tumor xenografts and induced cell apoptosis of HepG2 and SMMC-7721 tumor xenografts. Furthermore, BD0801 effectively reduced the vascular density and tumor tissue microvessel density (MVD). Similarly, BD0801 decreased AKT, Erk1/2, and Rb phosphorylation and cyclin D1 expression whereas it increased p21 protein expression in mouse HCC tumor xenografts. Importantly, BD0801 showed a better effect than Bevacizumab (Bev) on the inhibition of cell growth and induction of apoptosis in HCC cells in vitro and in vivo. These findings suggest that BD0801 is a potent anti-VEGF monoclonal antibody for the treatment of HCC. © 2017 Taylor & Francis Group, LLC.

α-fetoprotein-producing gastric cancer (AFPGC) is considered to be a special type of stomach cancer, due its features of high malignancy, fast progression, easy transferral and a poor prognosis. No standard therapy is currently available for patients with AFPGC. In the present study, the case of a 59-year-old male diagnosed with AFPGC and simultaneous liver metastases is presented. The patient presented with abdominal bloating and multiple liver lesions were revealed upon imaging. During the course of treatment, the patient’s serum AFP level increased to a maximum of 20,624.6 μg/l. The patient survived for 30 months and was ultimately treated with multimodal therapy, including surgery, chemotherapy, interventional therapy and molecular targeted therapy. Treatment with paclitaxel, irinotecan and TS-1, particularly sorafenib as a molecular targeted drug, are effective for such patients. The choice of chemotherapy regimen according to the Lauren classification and the use of oral sorafenib are likely to be novel and effective treatments for this type of stomach cancer. However, investigations should be performed to identify the gastric cancer patient population most receptive to sorafenib treatment. In addition, combined chemotherapy and molecular targeting treatment requires further study in order to determine if a synergistic effect is present. Further investigation in a large-sample study is required to confirm the validity of these results. © 2015 Spandidos Publications. All rights reserved.
