Abstract |
This chapter reported the pharmacokinetics and the toxicities of mitomycin-c (MMC) when administered as a hyperthermic intraperitoneal lavage after surgical resection of advanced primary or recurrent gastrointestinal cancer. Pharmacologic studies were performed in 10 patients and all adverse reactions were recorded in 20 patients. These 20 patients had advanced gastrointestinal malignancies with peritoneal carcinomatosis and underwent cytoreductive surgery prior to intraperitoneal lavage. Heated (42 degrees C) intraperitoneal mitomycin C was used in a lavage technique with 30 mg/3 1 of drug for 2 hours. The fluid was distributed throughout the abdominal cavity by vigorous external massage of the abdominal wall. This resulted in approximately 70 percent (21 mg) drug absorption from the perfusate. Urine output of MMC averaged 2.5 mg during the 2 hour procedure. Median peak blood levels of 0.25 micrograms/ml (range 0.11-0.41 micrograms/ml) were observed at 45-60 minutes into the procedure. Morbidity was low and was mainly related to the surgical procedures (prolonged ileus, postoperative fistulas) with mild to moderate drug-related myelosuppression. This new method of delivery of MMC and 5-FU should be explored in phase II clinical trials.
