Intraperitoneal chemotherapy for patients with advanced ovarian cancer: A review of the evidence and standards for the delivery of care

Objectives. To evaluate the role of intraperitoneal (IP) chemotherapy as part of primary treatment in patients with advanced ovarian cancer and to develop standards of care within the context of current clinical practice. Methods. A multidisciplinary expert panel, convened to develop standards on the use of IP chemotherapy, searched the MEDLINE, EMBASE, and Cochrane Library databases up to December 2006 for randomized trials or published standards on the efficacy and/or delivery of IP chemotherapy. Results. Eight randomized trials comparing IP chemotherapy versus intravenous (IV) chemotherapy were identified. Three trials reported statistically significant improvements in median survival of 8.0, 11.0, and 15.9 months with cisplatin-based IP chemotherapy. In one trial, the 15.9-month improvement in median overall survival (RR = 0.75, 95% CI = 0.58-0.97) represented a 25% reduction in the risk of death with IP chemotherapy. Severe adverse events and catheter-related complications were often dose limiting with IP chemotherapy. Using a consensus-based approach with a nationally representative panel, multidisciplinary care standards were developed to review medical and surgical criteria, the practice setting, volume requirements, and the institutional criteria required to safely deliver IP chemotherapy. Conclusion. The survival benefits with cisplatin-based IP chemotherapy may represent a significant improvement in the outlook for select patients with advanced ovarian cancer. The delivery of IP chemotherapy is more challenging than the IV route; however, severe adverse events and catheter-related complications may be offset through research defining the optimum treatment regimen, and the standardization of care. System-wide standards for the delivery of IP chemotherapy in Canada for patients with optimally debulked stage III ovarian cancer are offered. (c) 2007 Elsevier Inc. All rights reserved.
