Abstract

Background/Aims:The incidence of colorectal cancer has been increasing every year in Korea. Irinotecan- or oxaliplatin-based regimens including biologic agents are known to be effective in patients with advanced colorectal cancer. But in practice, FOLFOX (combination of oxaliplatin, 5-fluorouracil, and leucovorin) or FOLFIRI (combination of irinotecan, 5-fluorouracil, and leucovorin) regimens without biologic agents are more commonly used in Korea due to of the high costs of biologic agents. The aim of this study was to evaluate the efficacy and toxicity of FOLFIRI following FOLFOX4 in patients with advanced colorectal cancer.
Methods: A total of 54 patients with advanced colorectal cancer who were treated between May 2005 and May 2013 with FOLFOX4 as first-line chemotherapy and with FOLFIRI as second-line chemotherapy at Kosin University Gospel Hospital (Busan, Korea) were reviewed retrospectively.
Results:A total of 54 patients received second-line FOLFIRI chemotherapy. Five patients (9.3%) had a partial response, 29 patients (53.7%) had a stable disease. The median overall survival was 8.90 months and the median time to progression was 4.33 months. Toxicities were tolerable.
Conclusion: In a Korean population, FOLFIRI as second-line chemotherapy is effective and well tolerated in patients with advanced colorectal cancer after failure of FOLFOX4. Although the efficacy of FOLFIRI in this study was lower than that of second-line FOLFIRI with biologic agents, these results can help in the formulation of a treatment strategy for financially troubled patients.
