Irinotecan (CPT-11), a specific inhibitor of topoisomerase I, has been proven to be effective in the treatment of refractory or metastatic colorectal cancer. Furthermore, several first line phase III trials of the combination therapy (FOLFIRI) using CPT-11 and fuorouracil/leucovorin (5-Fu/LV) were reported to have significant improvement in treatment result. Therefore, we designed a multicenter clinical study to observe the overall survival (OS), time to death (TTD), time to progression (TTP), efficacy and safety of FOLFIRI regimen for patients with refractory or metastatic colorectal cancer after first line chemotherapy failure.
