Until recently, peritoneal carcinomatosis was a universally fatal manifestation of gastrointestinal cancer. However, two innovations in treatment have improved outcome for these patients. The new surgical interventions are collectively referred to as peritonectomy procedures. During the peritonectomy, all visible cancer is removed in an attempt to leave the patient with only microscopic residual disease. Perioperative intraperitoneal chemotherapy, the second innovation, is employed to eradicate small-volume residual disease. The intraperitoneal chemotherapy is administered intraoperatively with moderate hyperthermia. Part 1 of this two-part article, which appeared in the January issue, described the natural history of gastrointestinal cancer with carcinomatosis, the patterns of dissemination within the peritoneal cavity, and the benefits and limitations of peritoneal chemotherapy. Peritonectomy procedures were also defined and described. Part 2 discusses the mechanics of delivering perioperative intraperitoneal chemotherapy and the clinical assessments used to select patients who will benefit from combined treatment. The results of combined treatment as they vary in mucinous and nonmucinous tumors are also discussed.
