PKPD Modeling and Dosing Considerations in Advanced Ovarian Cancer Patients Treated with Cisplatin-Based Intraoperative Intraperitoneal Chemotherapy
Intraperitoneal chemoperfusion (IPEC) of cisplatin is a popular treatment for advanced ovarian cancer, typically under hyperthermia (HIPEC). The use of cisplatin under (H)IPEC is off-label, and the role of hyperthermia is unknown. The aim of this study was to characterize the pharmacokinetic/pharmacodynamic (PKPD) properties of cisplatin under (H)IPEC and to predict the optimal treatment regimen. Using a randomized design, data on intact cisplatin perfusate and plasma concentrations, leukocyte counts-a hematotoxicity marker-and serum creatinine-a nephrotoxicity marker-were collected from 50 patients treated with a combination of cytoreductive surgery (CRS) and either normothermic or hyperthermic IPEC of cisplatin dosed at 75, 100, and 120 mg/m
