Prospective multicenter phase II clinical trial of FOLFIRI chemotherapy as a neoadjuvant treatment for colorectal cancer with multiple liver metastases / 대한외과학회지
Forty-four patients with multiple (at least two) colorectal livermetastases were enrolled at seven tertiary referral hospitals between May 2007 and September 2010. All patients received the FOLFIRI chemotherapeutic regimen. Response to chemotherapy was assessed after three cycles (6 weeks) and once more after six cycles (12 weeks) of treatment.
RESULTS:
Objective response was noted in 27 patients (61.4%) and 4 patients (9.1%) had progressive disease. Of 44 patients, 10 patients (22.7%) underwent curative surgery (R0 resection) and 34 patients did not receive R0 resection. Grades 3 to 4 hematological toxicity was noted in 12 patients (27.3%) and grades 3 to 4 nonhematologic toxicity was identified in 5 patients (11.4%).
CONCLUSION:
FOLFIRI chemotherapy as a neoadjuvant chemotherapy for multiple colorectal livermetastases regardless of resectability demonstrated the possibility of R0 resection, high rate of objective response, and tolerable toxicities in this study.
