RESUMO
This study updates our experience with hepatic artery infusion chemotherapy for colorectal liver metastases at the Lahey Clinic. It compares surgical versus percutaneous catheter methods, employing an external pump. The surgical series (SS) consisted of 58 patients (1970-1995) treated with floxuridine (FUDR), 20 mg/d for 4 to 5 weeks (modified in 1985; 2-week cycles). Percutaneous series (PS) consisted of 42 patients (1976-1995) treated with fluorouracil (5-FU), 20 mg/d for 10 days followed by a floxuridine (FUDR) schedule as with SS. Analysis consisted of tumor response, survival, and toxicity data between the two methods. Response rates showed no significant difference, SS (34%) and PS (48%) (P = 0.22). There were no significant differences in survival from treatment until death in SS (n = 58) of 13 months versus PS (n = 42) of 10.6 months (P = 0.39), from diagnosis until death, SS being 28.4 months versus PS of 26.4 months (P = 0.71) and from metastases until death, SS being 17.4 months versus PS of 22.2 months (P = 0.35). Hepatic toxicity was similar, but there was increased bone marrow toxicity, mucositis, and diarrhea for the PS. Response rates are similar for both our SS and PS and to that reported in recently randomized surgical trials. Hepatic artery infusion chemotherapy with FUDR by percutaneous catheter placement may be as effective as surgical catheter placement for colorectal liver metastases, but further study is needed.
