The study determined the outcome of 1200 consecutive patients treated for peritoneal malignancy in one surgical unit over a 20-year period.


A retrospective analysis was conducted of a custom designed prospective database of patients undergoing surgery for peritoneal malignancy since 1994. Patient demographics, tumour type, extent of surgery and outcome were recorded.


Between 1994 and January 2014 (when the 1200th case had undergone surgery) 2956 patients were referred with a diagnosis of peritoneal malignancy. Pseudomyxoma peritonei of appendiceal origin was the pathology in 956/1200 (79.7%) patients. Other aetiologies included colorectal peritoneal metastases [89/1200 (7.4%)], abdominal mesothelioma [65/1200 (5.4%)] and miscellaneous [90/1200 (7.5%)]. Overall 863/1200 (71.9%) had complete cytoreduction, 294 (24.5%) had maximal tumour debulking and 43 (3.6%) had laparotomy only. The proportion undergoing complete cytoreduction per quartile of 300 patients was 60.7%, 65.0%, 77.0% and 80.3%. Laparotomy and biopsy fell from 6.4% in the first quartile to 2.7%, 1.7% and 1.3% in subsequent quartiles. The 30-day mortality in the four quartiles was 3.0%, 1.0%, 0.7% and 0.7%. The 5-year survival was 84% in the 636 patients with appendix tumours who had complete cytoreduction, 76% in the 38 with abdominal mesothelioma and 44% in the 60 with colorectal peritoneal metastases.


A centralized approach facilitated high volume experience in a single centre with an increase in the completeness of surgical excision rates and a reduction in mortality and morbidity over time.
