[Intraarterial chemotherapy using implantable port-catheter system in patients with colorectal liver metastases]

We evaluated the tentative clinical results of port-catheter system implantation in 32 patients (18 males and 14 females) with liver metastases of colorectal cancer (2001-2006). Laparotomic approach was used in 17 and percutaneous transfemoral implantation - in 15 patients. There were no complications nor technical problems. All patients received a total of 160 cycles of infusion chemotherapy, ranging 2-11 (4 on the average); mean follow-up - 241 (57-730) days . At present, 21 patients have survived for 5-28 months. Three of them (14%) report complete response, 13 (62%) - stabilization and 5 (24%) - tumor progression. One-year survival in all patients was in 76.5%. Eleven patients died through tumor progression unrelated to the liver.
