PIPAC for Peritoneal Metastases of Colorectal Cancer

Instead of standard palliative treatment, enrolled patients receive laparoscopy-controlled electrostatic pressurised intraperitoneal aerosol chemotherapy with oxaliplatin (ePIPAC-OX) (92 mg/m2 body-surface area \[BSA\]) with intravenous leucovorin (20 mg/m2 BSA) and bolus 5-fluorouracil (400 mg/m2 BSA) every six weeks. Four weeks after each procedure, patients undergo clinical, radiological, and biochemical evaluation. ePIPAC-OX is repeated until clinical, radiological, or macroscopic disease progression, after which standard palliative treatment is (re)considered.
