title: Intraoperative hyperthermic lavage with cisplatin for peritoneal carcinomatosis and sarcomatosis.
abstract: Intraoperative hyperthermic lavage with cisplatin was studied in 8 patients with peritoneal carcinomatosis and sarcomatosis. A dose of 50 mg/m2 of cisplatin used for 2 hours with an intraperitoneal temperature of 41 degrees to 43 degrees C was used. Pharmacokinetic studies showed that cisplatin left the abdomen and pelvis by simple diffusion with a half life of 48 minutes in the peritoneal fluid. Eighty-six percent of the drug was absorbed into the plasma within 2 hours but only 6.9% was excreted into the urine. The area under the curve ratio for peritoneal fluid to plasma was 6.9. The quantity of cisplatin in tissue from the abdomen or pelvis was extremely variable. It was 1.85-10.28 micrograms cisplatin/g tumor and < 0.57-7.90 micrograms/g normal tissue. Comparison of pharmacologic parameters of hyperthermic to normothermic cisplatin administration showed no significant differences.
