Abstract
Initial experiences reported increased surgical morbidities in patients receiving cytoreductive surgery for colorectal cancer after bevacizumab-containing chemotherapy; however, more recent literature suggests a favorable toxicity profile in patients with advanced ovarian cancer (AOC). With the aim of providing a more objective point of view on this controversial issue, we present here a systematic literature review. Systematic revision of the available literature was conducted using the PubMed, MEDLINE, and EMBASE electronic databases. All studies reporting safety data regarding cytoreductive surgery performed before or after bevacizumab-containing chemotherapy have been analyzed for the purposes of this study. The study has been prepared according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Forty-eight studies were retrieved from the electronic databases, with 23 (47.9%) being excluded due to an unsatisfactory study design. Among the remaining 25 manuscripts, 16 did not report data regarding surgical morbidities after cytoreductive surgery, therefore only 9 studies were included in the final analysis. Overall, 198 AOC patients received bevacizumab-containing neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) in the context of five studies, among whom 21 women experienced grade 3/4 postoperative complications (10.6%), which appears to be in line with data reported in patients receiving IDS after carboplatin-paclitaxel NACT. Results from phase I-II clinical trials, and dataset analysis from GOG-0218, did not observe an increased incidence of complications in AOC patients receiving bevacizumab-containing adjuvant chemotherapy after cytoreductive surgery. The incorporation of bevacizumab into first-line chemotherapy was not associated with increased morbidities before and after cytoreductive surgery in women with AOC.
