"Cetuximab 400 mg/mq intravenously (iv) with load dose of 400 mg/mq at the first cycle followed by 250 mg/mq iv weekly by iv infusion in 90 minutes. The administration of irinotecan will precede that of cetuximab and will consist on a dose of 180 mg/mq iv in 60 minutes every two weeks and it will be followed by fluorouracil (5-FU) at a dose of 400 mg/mq in slow iv bolus at half of lederfolin 200 mg/mq 2-hours infusion. At the end of the infusion of lederfolin an elastomeric pump loaded with 5-FU 2400 mg/mq in continuous 46 hours iv infusion will be applied. Only at the first administration of CT (load dose of cetuximab), irinotecan will not be administered."
