AbstractPeritoneal tumour dissemination is still considered as a terminal disease. For the last two decades, cytoreductive surgery (CRS) combined with intraoperative hyperthermic chemotherapy (HIPEC) has been popularised by Paul Sugarbaker almost doubling survival in selected patients compared with systemic chemotherapy alone. Nowadays, this particular treatment protocol is available in comprehensive cancer centres with reasonable mortality and morbidity. However, patient selection is still challenging. In general, CRS and HIPEC is indicated in primary peritoneal tumours such as mesothelioma and pseudomyxoma peritonei as well as in peritoneal metastases derived from gastrointestinal malignancies and ovarian cancers. Since systemic tumour spread is uncommon in patients with peritoneal metastases, peritoneal tumour dissemination was defined as localised disease within the "compartment abdomen". However, CRS and HIPEC are only beneficial as long as complete cytoreduction is achieved (CC-0 or CC-1). Histopathological parameters, the Sugarbaker peritoneal carcinomatosis index (PCI) and general condition of the patient have been established as patient selection criteria. In primary peritoneal cancers, individual tumour biology is the predominant criterium for patient selection as opposed to intraabdominal tumour load in peritoneal metastases derived from gastrointestinal cancers. In gastric cancer, CRS and HIPEC should be restricted to synchronous limited disease because of its biological aggressiveness. In patients with free floating cancer cells without macroscopic signs of peritoneal spread, however, CRS and HIPEC following preoperative "neoadjuvant" chemotherapy preserves chances for cure. So far, there is no general recommendation for CRS and HIPEC by clinical practice guidelines. In the recent S3 guideline for treatment of colorectal cancer, however, CRS and HIPEC have been included as possible treatment options. Georg Thieme Verlag KG Stuttgart · New York.
