Consolidation therapy is used in order to maximize the benefit of first-line therapy and to improve the progression-free and overall survival of patients. In women with advanced epithelial ovarian cancer, tested maintenance and consolidation strategies following first-line chemotherapy include high-dose chemotherapy, radiation therapy, intraperitoneal radionuclides including those linked to an antibody, and biological and immunologic agents. This review focuses on the current understanding of the benefit of radiation therapy and biological agents used as consolidation in women with advanced ovarian cancer. Whole abdominal radiation has given promising results only in the subgroup of patients with pathologic complete response. However, this treatment modality is associated with considerable intestinal toxicity. Single treatment with intraperitoneal radionuclides, either alone (32P) or in combination with an antibody (90Y-muHMFG1) has not improved survival. Biological agents used for consolidation include, eg, α- and γ-interferon, tanomastat, a matrix metalloprotease inhibitor and oregovomab, a murine antibody that targets CA125. Randomized trials with these agents have not demonstrated any significant improvement in the overall survival of ovarian cancer patients. Currently, two ongoing studies (GOG 218, ICON7) are examining the potential of bevacizumab in the maintenance therapy of advanced epithelial ovarian cancer. Evaluation of new agents is indicated in order to achieve long-term disease-free survival in these patients. Toxicity and ease of administration must be reflected against the benefits of therapy.
