Register With Patients in Which Hyperthermic Intra-Peritoneal Chemotherapy (HIPEC) Was Performed

Register With Data From Patients With the Diagnosis of a Peritoneal Surface Malignancy, for Which Cytoreductive Surgery and Hyperthermic Intra-Peritoneal Chemotherapy (HIPEC) is Performed

The purpose of this study is to register the follow-up data of patients who, because of a peritoneal surface malignancy, will undergo cytoreductive surgery and HIPEC.

To register the follow-up data of patients who, because of a peritoneal surface malignancy, will undergo cytoreductive surgery and HIPEC. In this surgical intervention, the abdominal cavity is macroscopically cleared of tumor, by removing all visible tumor nodules, and is subsequently rinsed with hyperthermic (heated) chemotherapy, aiming to destroy all residual invisible tumor cells that might have stayed behind after the debulking.

The eventual aim of this procedure is to improve the prognosis/survival of patients with malignancies localized on the peritoneal surface.

Inclusion Criteria:

• Patients with peritoneal carcinomatosis of colorectal origin, patients with pseudomyxoma peritonei (type DPAM or PMCA) and patients with peritoneal mesothelioma who are planned to undergo cytoreductive surgery and HIPEC because of a peritoneal surface malignancy
