Abstract

The purpose of this study was to use descriptive methodology to study the management of patients with pseudomyxoma peritonei (PMP) at the Princess Margaret Hospital. This is a case series of patients with a diagnosis of PMP treated between January 1, 1995 and December 31, 2001. A health record search using the morphology code for PMP was done and identified 70 patients. Additionally, an unrestricted Medline search was conducted between 1990 and 2002 for PMP. Eight cases of PMP were treated by the Gynecologic Oncology service at Princess Margaret Hospital during the study period. The patients ranged in age from 43 to 84 and presented with a pelvic mass and/or increasing abdominal girth. All but two patients underwent appendectomy as part of their surgery. Postoperative management was by gynecologic oncology for seven of eight patients. An appendiceal origin was confirmed for six patients and highly suspicious for one patient. The remaining patient underwent appendectomy, but it was not sufficiently sectioned for diagnosis. Chemotherapy was given to patients in a non-uniform fashion. Removal of mucinous tumors of the ovary should include appendectomy. Consultation from a general surgical oncologist should be sought where appendiceal origin is confirmed. Coding errors may occur in medical records at a frequency greater than is anticipated.
