Is there a role for intraperitoneal chemotherapy in the management of ovarian cancer?

Phase I and II clinical trial data have demonstrated the safety, pharmacokinetic advantage, and potential for enhanced cytotoxicity associated with the intraperitoneal administration of antineoplastic agents in the management of ovarian cancer. In two randomized phase III studies comparing the intraperitoneal and intravenous administration of cisplatin (Platinol) as initial therapy for small-volume residual advanced ovarian cancer, intraperitoneal delivery of the agent produced superior progression-free and overall survival. Reluctance to employ intraperitoneal cisplatin in the standard management of ovarian cancer appears to be related to the added time, effort, and potential morbidity associated with the approach, as well as a general preference for the less toxic, less complicated carboplatin (Paraplatin)-based regimen. However, existing data support the use of this unique method of drug delivery in carefully selected patients outside of the clinical trial setting.
