Prolonged survival of initially unresectable hepatic colorectal cancer patients treated with hepatic arterial infusion of oxaliplatin followed by radical surgery of metastases.
OBJECTIVE
The aim of this study was to analyze the impact of hepatic arterial infusion (HAI) of oxaliplatin with systemic 5-Fluorouracil and leucovorin on patients with isolated unresectable liver metastases.


METHODS
A total of 87 patients treated in our hospital with HAI of oxaliplatin with systemic 5-Fluorouracil and leucovorin for isolated unresectable colorectal liver metastases from May 1999 to May 2007 were extracted from a prospective database and analyzed. The resectability rate, perioperative findings, postoperative outcomes, and long-term follow-up were evaluated.


RESULTS
HAI was delivered after failure of previous systemic chemotherapy in 69 patients (79%). The main criterion for unresectability was massive liver involvement (86% of patients). Most patients had synchronous (85%), bilateral metastases (89%). The median number of HAI courses was 8 (0-25). About 31 patients experienced technical catheter-related problems, which were responsible for withdrawal of HAI in only 7 patients (8%). Finally, a total of 23 patients (26%) were operated on, and resection or radiofrequency ablation was performed in 21 patients (24%). No postoperative mortality was observed and the morbidity rate was 35%. Five-year overall survival was 56% in the surgery group versus none in the nonsurgery group (P < 0.0001). After a median follow-up of 63 months, intrahepatic recurrence occurred in 10 patients among the 23 operated patients.


CONCLUSIONS
HAI of oxaliplatin with systemic 5-Fluorouracil and leucovorin offers a second chance to remove initially unresectable isolated colorectal liver metastases in 24% of patients, and appears to be more efficient when performed as first-line therapy. Long-term overall survival can be obtained with this approach.
