Adjuvant HIPEC to Prevent Colorectal Peritoneal Metastases in High-risk Patients

Closed-abdomen HIPEC with cisplatin (25 mg/m2/l of perfusate) and mitomycin-C (3•3 mg/m2/l of perfusate) at 42•5°C for 60 minutes. Perfusate volume: 4-6 l.

Colon resections for primary tumors were performed according to the oncologic principles of adequate lymph-adenectomy. Complete adhesiolysis, resection of falciform hepatic ligament, greater and lesser omentectomy were performed in all patients to ensure optimal perfusion during the HIPEC. Tumor deposits on visceral and parietal surfaces were surgically removed by formal peritonectomy procedures and/or organ resections, as needed.
