Regional arterial chemotherapy of liver tumours. I. Performance comparison between a totally implantable pump and a conventional access system.

Thirty-nine patients with liver tumours have been submitted to regional arterial chemotherapy by means of either totally implantable Infusaid-400 pumps (22 c.) or implantable ports (17 c.). The latter were subsequently perfused with external pumps. There was one single major operative complication and no operative deaths. Most patients underwent continuous Fudr infusion. Access related complications occurred in both groups. Treatment was stopped for access related complications in 18.4% and 29.4% of cases out of the pump and port groups respectively. In most of those cases, however, several cycles of chemotherapy had already been performed. The Infusaid-400 pumps showed a 12-month functional duration of 57% with a 13-month median, the 10-month duration of ports being 67%. The difference was not significant. The new implantable systems give better results in comparison with traditional regional access methods, the functional performances of the port systems appearing very similar to the totally implantable pumps, with an obvious advantage for the pumps as far as quality of life is concerned.
