A fundamental study of regional chemotherapy given by intraarterial infusion with concomitant hemodialysis and hemoperfusion.

Abstract

In the intraarterial infusion of anticancer drugs, the majority of systemic side effects are caused by the systemic circulation of the infused drug. If the extraregional infusate could be removed by hemodialysis (HD) or direct hemoperfusion (DHP), side effects in the intraarterial infusion therapies could be mitigated and regional administration of anticancer drugs in large doses would than be possible. To substantiate this postulate, the authors carried out in vivo experiments using mongrel dogs, and obtained the results evidencing removal of extra regional anticancer drugs by HD and DHP. The maximum mitomycin C clearance of HD was 35.7 ml per min, whereas that of DHP was 119.7 ml per min. The results show the usefulness of concomitant use of HD or DHP in the intraarterial infusion of anticancer drugs via internal iliac artery in the treatment of cancer of the urinary bladder.
