The role of maintenance therapy and novel taxanes in ovarian cancer

Objectives.Despite several studies reporting various degrees of success, the role of maintenance chemotherapy in ovarian cancer remains controversial. This article reviews the available data and the controversy surrounding maintenance therapy. In addition, the role of novel taxanes, which may offer an improved therapeutic index and reduced toxicity relative to conventional therapies in this setting, is discussed.Methods.The available randomized clinical data on extended or maintenance therapy in ovarian cancer are reviewed.Results.Available data indicate that patients with ovarian cancer undergoing taxane maintenance chemotherapy exhibit a reduced recurrence rate and a longer progression-free survival.Conclusions.While an additional randomized trial is needed to confirm these benefits and establish maintenance therapy as the standard of care, the authors conclude that maintenance therapy is a valuable option that should be discussed with patients until further data are available. The Gynecologic Oncology Group 212 trial is a randomized clinical trial that is designed to answer whether taxane maintenance therapy offers a survival advantage as well as to determine the impact of such a therapeutic regimen on a patient's quality of life. This trial is also designed to address some of the questions regarding the role of a novel taxane in maintenance therapy in ovarian cancer.
