[Efficacy of CPT-11 combined 5-FU/CF (FOLFIRI) regimen on advanced colorectal cancer].

BACKGROUND & OBJECTIVE
Combination therapy of irinotecan, leucovorin (LV), and 5-fluorouracil (5-FU)(FOLFIRI regimen) has certain effect on advanced colorectal cancer. However, data of this regimen as first-line chemotherapy for Chinese patients with advanced colorectal cancer is still lacking, and its efficacy and safety still needs to be defined. This study was to explore the efficacy of FOLFIRI regimen as first-line chemotherapy on advanced colorectal cancer in Chinese patients, and observe its safety.


METHODS
Clinical data of 54 chemotherapy-naive patients with advanced colorectal cancer, treated with FOLFIRI regimen from Jan. 2002 to Sep. 2005 in Cancer Center of Sun Yat-sen University, were analyzed.


RESULTS
Of the 54 patients, 52 were evaluable for response. The overall response rate was 42.6%, the time to progression (TTP) was 6 months, and the overall survival time was 15.2 months. The most common drug-related adverse events were neutropenia (38.9%), diarrhea (37.1%) and nausea and vomiting (50.0%). The occurrence rates of these grade 3-4 events were 5.6%, 9.3%, and 9.3%, respectively. All adverse events were tolerable.


CONCLUSION
FOLFIRI regimen is effective and well-tolerated as first-line treatment for Chinese patients with advanced colorectal cancer.
