简要总结
The primary objective of this study is to determine whether systemic chemotherapy combined with hepatic arterial infusion with floxuridine and dexamethasone can increase the complete resection rate (R0) and improve the overall survival in patients with initially unresectable colorectal liver metastasis.
详细描述
Recent studies and our experience have proved the efficacy and safety of systemic chemotherapy combined with hepatic arterial infusion (HAI) with floxuridine and dexamethasone in patients with initially unresectable colorectal liver metastasis. However, most of them are retrospective studies, phase I or II clinical researches, which could not provide high-level evidence. Therefore, we designed this study to determine whether systemic chemotherapy combined with HAI can increase the complete resection rate (R0) and improve the overall survival in patients with initially unresectable colorectal liver metastasis.

研究组 & 干预措施
Systemic chemotherapy
Patients will receive mFOLFOX6 every 28 days: Oxaliplatin 85 mg/m2 IV over 3 hours on Day 1, 15; Leucovorin (l-LV) 200mg/m2 IV over 2 hours on Day 1, 15; followed by 5-Fluorouracil 2.4 g/m2 for 46 hours continuous infusion on Day 1, 15.
干预措施: mFOLFOX6 (Drug)
Systemic chemotherapy combined with HAI
Patients will receive mFOLFOX6+HAI every 28 days: Oxaliplatin 85 mg/m2 IV over 3 hours on Day 1, 15; Leucovorin (l-LV) 200mg/m2 IV over 2 hours on Day 1, 15; followed by 5-Fluorouracil 2.4 g/m2 for 46 hours continuous infusion on Day 1, 15. 0.12 mg/kg/day floxuridine (FUDR) and 25 mg dexamethasone in normal saline to a total volume of 300 ml will be administered through the HAI pump.
This will be repeated on Day 1 of each 28-day cycle. FUDR will be administered through a 14-day continuous infusion with the HAI pump.
