FOLFOXIRI With or Without Cetuximab as First-line Treatment of Patients With Non-resectable Liver - Only Metastatic Colorectal Cancer

PURPOSE: A primary aim of phase II FOCULM study is to explore whether cetuximab in combination with FOLFOXIRI as first treatment could improve surgical conversion in patients with KRAS/NRAS wild-type, unresectable liver - only metastases of colorectal cancer. The first secondary aim is to evaluate the safety and tolerability of the chemotherapy of FOLFOXIRI plus Cetuximab targeted therapy regimen in this patient population. Secondary aims include determination of objective response rate, progression free survival, quality of life and time to recurrence for patients undergoing complete resection and/or ablation of liver.
