Abstract:

Objective

To evaluate the efficacy and safety of anti-angiogenic agents combined with chemotherapy for patients with advanced gastric cancer.

Methods

We retrieved domestic and abroad authoritative database to find published literature of anti-angiogenic agents for advanced gastric cancer before July 2016. Quality of the included studies by the Jadad system evaluation method was assessed. Meta-analysis was performed using RevMan 5.3 software.

Results

Thirteen randomized controlled trials involving 3 174 patients were included. Meta-analysis indicated that anti-angiogenic agents group was better than chemotherapy alone or placebo group in overall survival (HR=0.83, 95% CI: 0.76-0.91, P<0.01), progression-free survival (HR=0.70, 95% CI: 0.57-0.87, P=0.001), complete response (OR=1.90, 95% CI: 1.08-3.35, P=0.03), partial response (OR=1.59, 95% CI: 1.32-1.90, P<0.01), overall response rate (OR=1.76, 95% CI: 1.36-2.27, P<0.01), and 1 year survival rate (OR=1.25, 95% CI: 1.05-1.47, P=0.01). In terms of safety, the incidence of adverse reactions of anti-angiogenesis drugs group was also higher in diarrhea (OR=1.93, 95% CI: 1.30-2.87, P=0.001), abdominal pain (OR=1.56, 95% CI: 1.11-2.17, P=0.009), hypertension (OR=5.95, 95% CI: 3.58-9.87, P<0.01), and proteinuria (OR=4.90, 95% CI: 1.29-18.66, P=0.02).

Conclusion

Anti-angiogenesis drugs can significantly increase the efficiency in the treatment of patients with advanced gastric cancer, and improve progression-free survival and overall survival, but it may increase the incidence of diarrhea, abdominal pain, hypertension and proteinuria.
