[A study of various complications in arterial infusion chemotherapy]

Complications of arterial infusion chemotherapy were analyzed in 261 cases from December 1983 to December 1993 in our department. Their complications involved nausea and vomiting (40.6%), bone marrow suppression (33.3%), liver dysfunction (20.3%), gastric and duodenal ulcer (9.6%) and so on. Complications involving an implantable device were hepatic arterial obstruction (29.1%), reservoir obstruction (5.7%), dislocation of catheter (4.6%), infection of catheter (3.8%), and obstruction of catheter (1.9%). In another cases with hepatic arterial obstruction, we performed arterial infusion in another artery as a bypass or stopped the infusion. In cases with obstruction of catheter not able to be reopened, we reinserted the catheter. An obstructed and/or infected reservoir was removed or replaced. Nausea and vomiting were found in 46.3% of FAM arterial infusion method (FAM) cases, in 53.3% of 5-FU persistent arterial method (5-FU) + FAM cases, and in 40.5% of intermittently persistent arterial method (IP) cases. Gastric and duodenal ulcer were noted in 9.8% of FAM, 13.3% of 5-FU + FAM, and 8.1% of IP cases. There were no significantly statistical differences between the methods. Hepatic arterial obstruction predominantly occurred in 32.4% of IP and 26.7% of 5-FU + FAM and bone marrow suppression was predominant in cases in which ADM was used. The duration of obstruction after administration was 154.0 +/- 117.4 days on average (21-455 days). Complications of hepatic arterial infusion chemotherapy are based on various causes which can be managed for prevention. We intend to enhance safety and assure the greater effectiveness of hepatic arterial chemotherapy.
