Methods：We carried out a cohort study evaluated the efficacy and safety of IRIS as first-line therapy in patients with advanced CRC. Forty-two eligible patients with previously untreated advanced CRC received irinotecan 180mg/m2 followed by S-1 80mg/m2 per day from day 1 to 9 every 2 weeks. The patients were followed intensively.Results：Forty patients were evaluated; the objective response rate was 45.0%（14/40 patients with partial response） in the treated population. Stable disease were observed in 22/40（55.0%） patients,disease control rate was achieved in 90.0% of all patients. The median progression-free survival（PFS） was 6.5 months（1.5 -10.0months）.The main toxicities including skin pigmentation,gastrointestinal reactions and bone marrow suppression. Grade 3/4 adverse events were occurred in 3 cases（7.5%）. There were no treatment-related deaths occurred. Conclusions：The IRIS regimen demonstrated an similar antitumor activity with present standard regimens. IRIS has well compliance and was well tolerated in patients with untreated advanced CRC. There was warranted to research IRIS combined with target therapy.
