VEGFA and ovarian cancer: Online databases, such as PubMed, Embase, and the Cochrane Library, were searched for relevant articles on the treatment of ovarian cancer patients with interval debulking surgery after neoadjuvant chemotherapy in combination with the bevacizumab regimen using the keywords “Ovarian Neoplasms,” “Bevacizumab,” “Monoclonal antibodies against vascular endothelial growth factor,” “Avastin,” and “Neoadjuvant Therapy.” A meta-analysis of the screened literature, which included randomized controlled trials and cohort studies, was then performed using Stata 15.0 software.
