Morbidity and mortality with cytoreductive surgery and intraperitoneal chemotherapy: the importance of a learning curve

Abstract

Evidence for the efficacy of cytoreductive surgery, combined with hyperthermic intraperitoneal chemotherapy (HIPEC), in the treatment of peritoneal carcinomatosis is accumulating. Many centers around the world now have considerable experience of the complex techniques required to achieve complete cytoreduction with the administration of HIPEC. Procedure-related morbidity ranges from 12% to 67.6% and mortality from 0% to 9% in recent studies of cytoreductive surgery and HIPEC for pseudomyxoma peritonei. A number of specialized centers have studied the factors that influence perioperative complications and mortality and have demonstrated impressive reductions in morbidity and mortality over time. However, for this treatment to be accepted as standard of care, teams undertaking this treatment strategy must aim to minimize morbidity and mortality by learning from the experience of established centers and using the "global learning curve."
