Management of recurrent ovarian carcinoma: current status and future directions

The majority of patients who present with epithelial ovarian cancer respond well to the initial treatment, but will ultimately experience a recurrence of their disease. Chemotherapy can palliate symptoms of disease recurrence, and there is some evidence that it also can improve survival. Recurrent ovarian carcinoma is divided into two subsets of patients: those with platinum-sensitive disease and those with platinum-resistant disease. Management for these two groups has diverged in the last few years, as evidence accrues that the response to treatment and duration of treatment-free interval after completion of front-line therapy impacts the prognosis and the treatment choice for these patients. Recent randomized trials have demonstrated a benefit for platinum combination re-treatment in patients with platinum-sensitive disease. Additionally, there are multiple single-agent trials evaluating novel agents for patients with platinum-resistant as well as platinum-sensitive disease. This review will discuss the role of chemotherapy in recurrent disease, describe the various agents used in this setting, and touch on the role of biologic agents in recurrent epithelial ovarian carcinoma.
