SUMMARY An estimated 75% to 85% of ovarian cancer patients have advanced-stage disease at diagnosis. The five-year survival for early disease (stage I) is 94% compared with 46% for all patients with ovarian cancer. Optimal surgical debulking followed by adjuvant chemotherapy remains the standard of care for patients with advanced ovarian cancer. Standard first-line systemic therapy is the combination of a platinum agent and a taxane. Intraperitoneal chemotherapy is recommended, having demonstrated a survival advantage over intravenous delivery. Adverse events are more common and potentially more severe with intraperitoneal chemotherapy, but strategies exist to minimize these effects.
SUMMARY (cont.) Treatment for relapsed or recurrent ovarian cancer is additional chemotherapy, possibly following additional surgery. The choice of systemic therapy for relapsed or recurrent ovarian cancer depends on the interval from first-line therapy, commonly called the platinum-free interval. Recurrence within six months of first-line therapy is considered platinum-resistant and generally not responsive to additional platinum-based chemotherapy. A platinim-free interval of six months or greater defines platinum-sensitive disease and platinum-based chemotherapy is included among the options for second-line and subsequent lines of chemotherapy.
SUMMARY (cont.) Currently, no targeted therapy has an approved indication for advanced ovarian cancer. However, bevacizumab has demonstrated potential to improve outcomes when used in conjunction with conventional chemotherapy. Monitoring patients with CA125 testing has not been shown to improve survival. However, the decision to use CA125 monitoring should be left to the discretion of the patient and treating physician. A critical need exists for a means to diagnose more patients with early-stage disease.
