Abstract
Despite optimal surgery and appropriate first-line chemotherapy, ∼70%–80% of patients with epithelial ovarian cancer will develop disease relapse. The same modalities as used primarily are available for treatment of recurrent ovarian cancer (ROC). The rationale for repetitive surgery in ROC was based on a stable body of retrospective data; however, prospective data were missing. Now, preliminary data from the prospective AGO-DESKTOP III give evidence that surgery for ROC seems to be of benefit for selected patients with platinum-sensitive relapse undergoing complete resection. With respect to systemic therapy, tumor histology, BRCA status, the platinum-free interval (PFI) and previous treatment with bevacizumab (anti-VEGF monoclonal antibody) are considered the most important features that influence treatment choice in ROC. In patients with resistant or refractory relapse (PFI < 6 months), monotherapy with a non-platinum drug or participation in clinical trials is indicated. The association of non-platinum monotherapy with bevacizumab, followed by maintenance has been approved in this setting in some European countries due to PFS benefit. In patients with partially sensitive relapse (PFI between 6 and 12 months), two options are available: platinum doublets or non-platinum therapy (single agent or combination). The pegylated liposomal doxorubicin/trabectedin combination represents a viable alternative in patients that cannot receive platinum. In platinum-sensitive patients, treatment with platinum-based combinations is associated with PFS advantage compared with single agents or non-platinum combinations. The presence of germline or somatic BRCA mutations allows platinum-responsive patients to optimize chemotherapy efficacy and prolonging PFS by the use of olaparib (PARP inhibitor) given as maintenance therapy until progression. In patients not pretreated with bevacizumab in first line, the carboplatin/gemcitabine/bevacizumab combination, followed by maintenance is a viable alternative in platinum-sensitive patients (PFI> 6 months). The integration of surgery, with a ‘personalized’ approach by the use of antiangiogenic agent and of PARP inhibitors is affecting survival of patients with recurrent disease and will help epithelial ovarian cancer to become a chronic disease.
