Aims: The prognosis of patients with peritoneal carcinomatosis from gastrointestinal malignancies is poor. The aim of this study was to analyse the results of multimodality treatment for peritoneal carcinomatosis of appendiceal carcinoma. Patients and methods: From 07/95 to 01/00, 17 patients (13 males, 4 female, median age 58 years) underwent peritonectomy procedures in combination with intraperitoneal hyperthermic chemotherapy. Surgical, pathological and survival data were analysed retrospectively. Results: All patients had undergone previous surgical treatment and one patient had received chemotherapy. In all patients peritonectomy procedures, as described by Sugarbaker, were performed with the aim of achieving a macroscopically complete cytoreduction (range 2–6, median 4 procedures per patient). Following resection, open hyperthermic intraperitoneal chemotherapy with cisplatin was performed. Eleven patients had postoperative com- plications (predominantly ‘‘non-surgical’’) and two patients died postoperatively. The 4-year survival rate was 75%. Complete cytoreducion had a statistically significant positive influence on long-term survival. Conclusions: In selected patients (WHO status 0/1, minimal residual disease, no distant metastases, complete cytoreduction), the prognosis for patients with peritoneal carcinomatosis of appendiceal origin can be improved by peritonectomy procedures and hyperthermic intraperitoneal chemotherapy. Postoperative morbidity may be increased due to ‘‘non-surgical’’ complications. Key words: appendiceal carcinoma; peritonectomy; intraperitoneal chemotherapy. INTRODUCTION
