Abstract

Objective

Neoadjuvant chemotherapy followed by interval debulking surgery is an alternative for the management of advanced ovarian cancer (AOC). Owing to unresectable disease at initial evaluation, some patients received bevacizumab in addition to neoadjuvant chemotherapy. The aim of this study was to evaluate the safety and postoperative course of patients who had received bevacizumab before debulking surgery for AOC.

Methods

In 2012, we identified all patients with AOC who had received neoadjuvant bevacizumab before debulking surgery. We recorded patients’ characteristics, surgical course, and postoperative complications.

Results

Five patients were identified, of whom 80% were International Federation of Gynecology and Obstetrics stage 4 at diagnosis. All patients underwent surgery after 6 courses of neoadjuvant chemotherapy with carboplatin, paclitaxel, and bevacizumab. The median number of bevacizumab injections was 3 (3–4), and the median time between the last injection of bevacizumab and surgery was 54 days (34–110 days). One patient had a grade 3 complication (lymphocyst with puncture under computed tomographic scans).

Conclusion

In this preliminary study, debulking surgery after neoadjuvant chemotherapy that included bevacizumab did not increase the rate of postoperative complications when there was a reasonable interval between the last bevacizumab injection and surgery. Larger studies are warranted to assess surgical safety after antiangiogenic treatment in the neoadjuvant setting for advanced ovarian cancer.
