A new strategy currently under evaluation in patients with peritoneal carcinomatosis from gastrointestinal and gynecologic cancers is perioperative intraperitoneal chemotherapy. Although results to date show benefit to carefully selected groups of patients, continued local-regional failure is seen in many treated patients. Continued clinical and laboratory research efforts to improve local-regional effects are desired. The chemotherapeutic agents that have been used in the past or are currently being tested were reviewed. Their pharmacologic properties and clinical features were collected from the medical literature and are reviewed in the text. An organized presentation of available data concerning the drugs available for perioperative intraperitoneal chemotherapy for peritoneal surface malignancy was made. From this review, new possibilities for improved doses, schedules, and drug combinations for perioperative intraperitoneal chemotherapy may become important in future clinical studies. Continued optimal utilization of intraperitoneal chemotherapy treatments in the operating room with hyperthermia or normothermic treatment in the early postoperative period is desirable. Innovative treatment strategies can improve the outcome of patients with peritoneal surface malignancy. The Oncologist

In these carcinomatosis patients clinical and CT assessment of response to neoadjuvant chemotherapy seldom provided useful data over this short time period. Intraoperative findings indicated progression in 50% of patients. By histopathology, 29% of patients had a response.
