Intraperitoneal chemotherapy for the initial management of primary epithelial ovarian cancer.

Ovarian cancer tends to be chemosensitive and confine itself to the surface of the peritoneal cavity for much of its natural history. These features have made it an obvious target for intraperitoneal chemotherapy. Chemotherapy for ovarian cancer is usually given as an intravenous infusion repeatedly over 5 to 8 cycles. Intraperitoneal chemotherapy (IP) is given by infusion of the chemotherapeutic agent directly into the peritoneal cavity. This may increase the anticancer effect with fewer systemic adverse effects in comparison to intravenous therapy.
