摘要
Brain metastases from ovarian cancer remain rare and the appropriate treatment is unknown. We investigated survival outcomes following salvage chemotherapy before and after bevacizumab approval to evaluate the efficacy of bevacizumab in patients with brain metastasis from ovarian cancer.We investigated 23 consecutive patients with brain metastasis from ovarian cancer at our hospital between 2001 and 2020. Bevacizumab was administered for treating ovarian cancer after approval in Japan in November 2013. Survival after brain metastasis was compared between 9 patients treated before bevacizumab approval (2000-2013) and 14 patients treated after approval (2014-2020). Seven patients treated in the latter period received bevacizumab-salvage chemotherapy for brain metastasis.Median survival in all patients was 9.1 months [95% confidence interval (CI)=4.2-33.5]. In addition, patients treated during the latter period presented better survival outcomes than those treated in the former period (former, 2.9 months vs latter, 33.5 months, log-rank test, p=0.015; Wilcoxon test, p=0.009). Multivariate analysis revealed that bevacizumab addition (p=0.020), interval to brain metastasis (p=0.005), number of brain lesions (p=0.001), number of recurrences (p=0.001), and platinum sensitivity (p=0.028) were independently associated with survival in all cohorts.Bevacizumab-based salvage chemotherapy may improve survival outcomes in patients with brain metastasis.
