Real-world Efficacy and Safety of Bevacizumab for Advanced or Recurrent Müllerian Cancer: A Single-institutional Experience.

Abstract

The efficacy and safety of bevacizumab for ovarian cancer have been reported in randomized phase III clinical trials. It is important to gather experience and data in a real-world setting. The objective of the present study was to evaluate the efficacy and safety of bevacizumab for patients with ovarian cancer in a real-world setting. For front-line settings, patients with FIGO stage III-IV ovarian cancer treated using bevacizumab and chemotherapy after debulking surgery (Chemo + Bev group, n=79), in addition to those treated with only chemotherapy after debulking surgery (Chemo group; n=66), at our institute were reviewed retrospectively. For recurrent settings, patients with recurrent ovarian cancers treated with bevacizumab and any chemotherapy were reviewed retrospectively (n=65). In the front-line setting, the disease-free survival was significantly longer in the Chemo + Bev group compared with that in the Chemo group (p=0.021). Hypertension and proteinuria were found to be statistically more frequent in the Chemo + Bev group compared with that in the Chemo group (p=0.002 and p=0.004). In the recurrent setting, in platinum-sensitive patients, the response rate (RR) and the disease control ratio (DCR) were 78.4 and 94.1%, respectively. In platinum-resistant patients, the RR and the DCR were 28.6 and 57.1% respectively. The median progression-free survival was 18.3 and 7.1 months for platinum-sensitive recurrence and platinum-resistant recurrence, respectively. The major ≥ grade 3 adverse event was neutropenia. The present study provided encouraging real-world evidence of the efficacy and safety of bevacizumab for ovarian cancer in real-world.
