BACKGROUND: Response rates to systemic chemotherapy are low after tumor progression on oxaliplatin regimens. Hepatic arterial infusion (HAI) therapy in patients with tumor progression is a viable alternative.
PATIENTS AND METHODS: Thirty-nine heavily pre-treated patients (all receiving prior oxaliplatin) with unresectable colorectal hepatic metastases were treated with systemic CPT-11 and concurrent HAI floxuridine (FUDR) and dexamethasone (DEX).
RESULTS: Partial responses were seen in 44% of patients. Median time to hepatic progression was 8.6 months, and median time to overall progression was 6.5 months. Median survival from time of initiation of HAI was 20.1 months [95% confidence interval (CI) 16.9-21.4] and from the initiation of treatment of metastatic disease, 32.01 months (95% CI 29.1-34.6). After a median follow-up of 19.1 months, seven patients (18%) proceeded to potentially curative surgery. Grade 3/4 toxic effects included neutropenia (13%), diarrhea (15%), intra-abdominal hemorrhage (2%), and bleeding duodenal ulcer (2%). Elevated liver function tests were seen, including bilirubin concentration >3 mg/dl (7%), alkaline phosphatase 2X baseline (20%), and aspartate aminotransferase >3X baseline (26%).
CONCLUSIONS: HAI FUDR/DEX plus systemic CPT-11 achieves a response rate of 44% and a median overall survival of 20 months in heavily pre-treated patients with colorectal hepatic metastases all receiving previous oxaliplatin; 18% of patients proceeded to surgical resection or ablation.
