Background:
Pseudomyxoma peritonei, a tumor which spreads chiefly along peritoneal surfaces, has recently been treated by resection followed by intraperitoneal infusion of 5-fluorouracil (5-FU). Reports on the cardiotoxicity of this drug, given intravenously, indicate an incidence of 1.4-2.9%. Although several deaths have been reported following 5-FU therapy by continuous intravenous infusion, none has apparently been reported following bolus intravenous injection.
Method:
Radical resection of an extensive pseudomyxoma peritonei was performed. Following convalescence, intraperitoneal infusion of 5-FU was initiated in a daily dose of 20 mg/kg body weight (1,440 mg), planned for administration in multiple 5-day cycles.
Results:
After three uneventful daily infusions of 5-FU, the patient suddenly died, apparently of a sudden cardiac event. Autopsy provided no explanation for his death. The coronary arteries were free of disease and no residual tumor was found. A review of the literature reveals no report of a cardiac death from 5-FU following its intraperitoneal administration.
Conclusions:
The fatality suggests the potential toxicity of 5- FU when administered intraperitoneally, a factor to be considered in decisions to use this drug intraperitoneally.
