Pseudomyxoma peritonei: treatment with intraperitoneal 5-fluorouracil.

Four patients with pseudomyxoma peritonei associated with mucinous tumors of the ovary were treated with cytoreductive surgery followed by intraperitoneal (IP) 5-fluorouracil (5-FU). CA-125 was elevated in three, and ca cinoembryonic antigen (CEA) in one patient; both fell to within normal levels following treatment. Two patients underwent reassessment laparotomy and one a reassessment laparoscopy with no evidence of disease following chemotherapy. The fourth patient refused surgical reassessment but remains clinically free of disease. Intraperitoneal 5-FU appears to be effective in pseudomyxoma peritonei. Précis: Four patients with pseudomyxoma peritonei associated with ovarian tumors were successfully treated with surgery and intraperitoneal 5-FU.
