title: Surgical treatment of disseminated peritoneal metastases from urological cancer: results from a prospective study.
abstract: OBJECTIVE
  To report a prospective phase II study of patients with disseminated peritoneal carcinomatosis and symptomatic disease, in whom the peritoneal metastases were resected.
  
  
  METHODS
  From 1995 to 1999, 32 patients (20 men and 12 women, median age 56 years, range 32-75) with peritoneal carcinomatosis were enrolled in the trial. Pain and ascites were determined according to the National Cancer Institute score/criteria, and performance scored according to the World Health Organisation criteria.
  
  
  RESULTS
  All patients had intraperitoneal disseminated malignancies with clinically evident ascites, and presented with abdominal pain. The median (range) operative duration was 2.9 (1-5.5) h and the hospital stay 25 (10-44) days, with no deaths at 30 days. The ascites was completely cured in 25 of the 32 patients, pain relieved in 28 and the performance score improved in 25. The median survival time was 1 year; the 1- and 2-year survival rates were 45% and 38%, respectively. Patients with residual metastases after incomplete resection had a significantly worse prognosis, but the prognosis was significantly better in those with a low tumour burden.
  
  
  CONCLUSIONS
  Peritoneal carcinomatosis is treatable; radical peritonectomy improves the performance score in selected patients with cancer-related ascites and/or pain, and is now the standard approach in the authors' Cancer Centre.
