[Performance and complications of totally implantable port device in bolus hepatic intra-arterial chemotherapy]. / Funzionalità e complicanze dei "port" totalmente impiantabili per la chemioterapia intraarteriosa epatica in bolo.

ABSTRACT

The performances of totally implantable ports were analyzed in patients with colorectal metastases undergoing intraarterial treatment. Seventy-nine patients received bolus infusion of Cisplatin (DDP, 57 cases) or Epirubicin (EPI, 22 cases) every 21 and 7 days, respectively. Disease progression or toxicity were the most common causes of interruption of treatment, whereas failure of ports occurred in six and two patients out of DDP and EPI groups, respectively. The incidence of single problems for each port was 65% in DDP group and 64% in EPI group, whereas rate of complications for each patient was 30% and 32%, respectively. The 12-months device duration rate in the two groups was 65% (median 17 months) in DDP group and 78% (median 18 months) in EPI group. The implantable ports employed for bolus arterial infusion, allowed adequate treatment periods in most cases, without any difference as far as intervals between cycles is concerned.
