The peritoneal cavity is a common site of metastasis from colorectal cancer, and patients often have aggressive tumor biology and poor prognosis. Cytoreductive surgery-hyperthermic intraperitoneal chemotherapy is the only effective treatment for suitable patients. The benefit of this treatment is controversial, and current strategies to prevent metastasis in high-risk individuals have been shown to be ineffective.
The peritoneal cavity is a common site of metastatic spread from colorectal cancer (CRC). Patients with peritoneal metastases (PM) often have aggressive underlying tumor biology and poor survival. While only a minority of patients with CRC have potentially resectable disease, the high overall incidence of CRC makes management of PM a common clinical problem. In this population, cytoreductive surgery (CRS)-hyperthermic intraperitoneal chemotherapy (HIPEC) is the only effective therapy for appropriately selected patients. In this narrative review, we summarize the existing literature on CRS-HIPEC in colorectal PM. Recent prospective clinical trials have shown conflicting evidence regarding the benefit of HIPEC perfusion in addition to CRS. Current strategies to prevent PM in those at high-risk have been shown to be ineffective. Herein we will provide a framework for clinicians to understand and apply these data to treat this complex disease presentation.
