Escalated Dose of Irinotecan in mCRC

"The investigators will use the regimen as following:~Regimen for treatment consisted of bevacizumab (Avastin) 5mg/Kg (IV infusion) on day 1, follow by irinotecan (180 mg/m2 as a 120-min IV infusion), Leucovorin (400 mg/m2 IV infusion over 2 hours), and 5-FU (2800 mg/m2 IV infusion over a 46-hour period), repeated every 2 weeks.~After 2 cycles of each different dose of irinotecan, we will observe the adverse effects (AEs) of hematological / non-hematological. If the grade is under the grade 2, we will escalate the dose of 30 mg/m2 gradually. The estimated maximal dose of irinotecan is 260 mg/m2."
