ABSTRACT
BACKGROUND:
Peritoneal metastases (PM) are a form of metastatic spread affecting approximately 5-15% of colon cancer patients. The attitude towards management of peritoneal metastases has evolved from therapeutic nihilism towards a more comprehensive and multidisciplinary approach, in large part due to the development of cytoreductive surgery (CRS), usually coupled with heated intraperitoneal chemotherapy (HIPEC), along with the constant improvement of systemic chemotherapy of colorectal cancer. Several landmark studies, including 5 randomized controlled trials have marked the development and refinement of surgical approaches to treating colorectal cancer peritoneal metastases.METHODS:
This review article focuses on these landmark studies and their influence in 4 key areas the evidence supporting surgical resection of peritoneal metastases, the identification and standardization of important prognostic variables influencing patient selection, the role of surgery and intraperitoneal chemotherapy in prevention of colorectal PM and the role of intraperitoneal chemotherapy as an adjuvant to surgical resection.RESULTS:
These landmark studies indicate that surgical resection of colorectal PM should be considered as a therapeutic option in appropriately selected patients and when adequate surgical expertise is available. Standardized prognostic variables including the Peritoneal Cancer Index and the Completeness of Cytoreduction Score should be used for evaluating both indications and outcomes.CONCLUSIONS:
Current evidence does not support the use of second look surgery with oxaliplatin HIPEC or prophylactic oxaliplatin HIPEC in patients with high risk colon cancer nor the use of oxaliplatin HIPEC with CRS of colorectal PM.
