[Clinical practice guideline on peritoneal carcinomatosis treatment using surgical cytoreduction and hyperthermic intraoperative intraperitoneal chemotherapy].

In 2005, the Comité de l'évolution des pratiques en oncologie (CEPO) took it upon itself to develop a clinical practice guideline to determine the clinical value of surgical cytoreduction followed by hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) for treating peritoneal carcinomatosis stemming from colorectal cancer, cancers of the appendix and stomach, pseudomyxoma peritonei, and mesothelioma of the peritoneum. A review of the scientific literature was performed using the PubMed search engine. The period covered extended from January 1990 to January 2006, inclusively. The scientific literature search was limited to clinical trials (minimum phase II) and organizations elaborating clinical practice recommendations. Twenty-six studies were identified. Of these, only one was phase III. Although some of these studies have demonstrated a benefit from this treatment in terms of patient survival, HIPEC remains a complex procedure whose optimal use is uncertain. Given the morbidity and mortality associated with this treatment, this procedure requires a high level of expertise. Considering the evidence available, the CEPO recommends: 1) that complete cytoreduction followed by HIPEC be used in a clinical research context only, preferably in the presence of an isolated peritoneal carcinomatosis stemming from colorectal cancer, cancer of the appendix, peritoneal pseudomyxoma, or mesothelioma of the peritoneum; 2) that studies be conducted only in specialized centers with the necessary expertise and technical resources.
