Peritoneal carcinomatosis (PC) is one of the routes of dissemination of abdominal neoplasms and is generally considered a lethal disease, with a poor prognosis by conventional chemotherapeutic treatments. While systemic chemotherapy has little impact on the treatment of peritoneal disease, some centers have reported encouraging results with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC). This approach is based on surgical cytoreduction of the primary tumour, peritonectomy (stripping of implants on the peritoneal surface) and HIPEC. The rationale of this treatment, after macroscopic disease removal, is to obtain an elevated and persistent drug concentration in the peritoneal cavity, with limited systemic effects. Many studies have reported encouraging results on overall survival (OS) and the disease-free interval in patients affected by PC. ⋯ Correct patient selection based on a maximum PCI of 16, associated with complete cytoreduction (CCR-0), produced encouraging results in our experience. To improve this encouraging survival outcome, it is very important to unify the surgical experience of expertise centres. Our results also suggest the need for an integrated approach to this condition to identify the correct aspect of the surgical domain and results that may be influencing the prognosis and the evolution of this patients.
