Cytoreductive Surgery and Perioperative Intraperitoneal Chemotherapy: A New Standard of Care for Appendiceal Mucinous Tumors with Peritoneal Dissemination

ABSTRACT

In the past, mucinous appendiceal tumors and the pseudomyxoma peritonei syndrome were treated with serial debulking procedures. Some benefit was achieved, but no long-term survivals were seen. A new standard of care that involves the complete removal of all visible disease using peritonectomy procedures combined with intraperitoneal chemotherapy washing has developed. This new approach is jeopardized when extensive prior surgical procedures have violated the peritoneum as a first line of defense of the host against carcinomatosis. In patients who have a complete cytoreduction, a 5-year survival of 80% is expected. In patients who have an incomplete cytoreduction, no 10-year survivors are seen. These studies suggest a new standard of care for appendiceal mucinous tumors with peritoneal dissemination.
