This study aims to assess the survival of patients who underwent peritonectomy, to assess the morbidity and mortality associated with the procedure and to review the published reports on the survival of patients with peritoneal spread of colorectal cancer (CRC).

Peritonectomy involves resection of all visible peritoneal tumour and is followed by heated intraperitoneal chemotherapy. Peritonectomy with heated intraperitoneal chemotherapy is associated with a 3-year survival of 30–50% in patients with low peritoneal cancer index (PCI) with peritoneal carcinomatosis from CRC. There are approximately 1000 patients in phase 2 studies and a large survival advantage was shown in a randomized control trial. We have carried out over 100 peritonectomy procedures. This study describes 22 patients with peritoneal spread of gastrointestinal cancer treated with peritonectomy between 1996 and March 2005. Twenty of these patients had primary colorectal cancer and two patients had primary small bowel cancer.

Of the 22 patients who underwent peritonectomy, 8 patients are now deceased. The median follow up is now 16.1 months. At 12 months, the survival was 61.5% and at 24 months the survival was 46.1%, which are creditable results comparable with the world published reports. We found that those patients with all macroscopic residual tumour removed at the end of the procedure (completeness of cancer resection, CCR O) had improved 24-month survival compared with patients in whom there was incomplete tumour resection (53.3% survival vs 22.2%, respectively, P = 0.024). Patients with a PCI score less than 13 had better survival (P = 0.0003).

Peritonectomy for peritoneal carcinomatosis from CRC offers patients improved survival. Our results are consistent with the published data with respect to improved survival in patients with low PCI and complete cytoreduction.
