Phase IV Multi-Institutional Randomized Trial of Capecitabine Plus Oxaliplatin With Bevacizumab in Patients With Potentially Resectable Gastric Cancer With Liver Metastasis
Phase IV Multi-Institutional Randomized Trial of Capecitabine Plus Oxaliplatin With Bevacizumab in Patients With Potentially Resectable Gastric Cancer With Liver Metastasis
The investigators assessed whether the addition of a preoperative regimen of Bevacizumab regimen to improves R0 resection rate and survival among patients with potentially resectable gastric cancer with liver metastasis.
Groups 1:Capecitabine Plus Oxaliplatin With Bevacizumab in Patients With Potentially Resectable Gastric Cancer With Liver Metastasis.
Groups 2:Capecitabine Plus Oxaliplatin With placebo in Patients With Potentially Resectable Gastric Cancer With Liver Metastasis.
Group 1 compare with Group 2 in disease-free survival time. Stage I：Preoperative therapy Capecitabine Plus Oxaliplatin With Bevacizumab is superior to Capecitabine Plus Oxaliplatin alines.
Stage II: therapy after surgery Capecitabine Plus Oxaliplatin With Bevacizumab is superior to Capecitabine Plus Oxaliplatin alones after surgery for over 6 months in all.
