Abstract:
PURPOSE: We evaluated whether adding bevacizumab to current platinum-based chemotherapy could improve clinical outcomes without affecting safety.MATERIALS AND METHODS: We retrospectively reviewed medical records of patients with pathologically confirmed ovarian cancer who received neoadjuvant chemotherapy (NAC) at Yonsei Cancer Hospital. We divided the patients into groups based on the use of bevacizumab for NAC (CP group: carboplatin+paclitaxel vs. BCP group: bevacizumab+carboplatin+paclitaxel) and compared patient characteristics, responses to NAC, and surgical and survival outcomes between the two groups. Overall, 88 patients in the CP group and 16 patients in the BCP group received NAC. The primary endpoint was survival outcomes. Complete resection rate after interval debulking surgery (IDS), cancer antigen 125 (CA-125) normalization after NAC, and chemotherapy response score were secondary endpoints.RESULTS: After NAC treatment, all patients underwent IDS. There were no significant differences in adverse events during NAC or postoperative complications between the two groups (p=0.293 and p=0.485, respectively). There were also no significant differences in CA-125 normalization after NAC (42.0% vs. 43.8%, p=0.899) or complete resection rate after IDS (47.7% vs. 56.3%, p=0.530). However, although the BCP group did not show longer overall survival (OS) (log-rank p=0.854), they had significantly longer progression-free survival (PFS) than the CP group (log-rank p=0.048).CONCLUSION: Bevacizumab-containing NAC might be safe and provide longer PFS than chemotherapy alone in patients with advanced ovarian cancer. However, further study is necessary to investigate the impact of bevacizumab-containing NAC on OS.
