BACKGROUND: Pseudomyxoma peritonei is a rare clinical entity in which the peritoneal surfaces and omentum are involved with diffuse gelatinous mucinous implants. It originates from ruptured mucinous tumors of the appendix or ovary.
METHODS: The authors examined the experience with 34 patients with pseudomyxoma peritonei seen at Memorial Sloan-Kettering Cancer Center from 1952-1989. Of these, 17 cases were identified to be of appendiceal origin.
RESULTS: All patients underwent celiotomy and cytoreduction. The median survival time from diagnosis was 75 months. It was found that long-term survival can be achieved by operation alone. When conditions do recur, chemotherapy may be valuable.
CONCLUSIONS: Pseudomyxoma peritonei of appendiceal origin is a rare low-grade malignancy. Initial treatment consists of cytoreduction in an attempt to render the patient locally disease-free. Long-term survival can be obtained by operation alone, even if gross disease is present at the end of the procedure. Systemic chemotherapy should be reserved for patients with proven recurrence.
