Concurrent irinotecan, oxaliplatin and UFT in first-line treatment of metastatic colorectal cancer: a phase I study.Sheikh HY, Valle JW, Palmer K, Sjursen A, Craven O, Wilson G, Swindell R, Saunders MP Department of Clinical Oncology, Christie Hospital NHS Trust, Manchester M20 4BX, UK. The feasibility of combining UFT plus leucovorin (LV) with alternating irinotecan and oxaliplatin was investigated in the first-line treatment of patients with advanced colorectal cancer. Twenty-five patients, median age 63 (range 24-79) years, World Health Organisation performance status 0-2 and median four marker lesions, received irinotecan 180 mg m(-2) on day 1, oxaliplatin 85-100 mg m(-2) on day 15 and UFT 200-300 mg m(-2) day(-1) with LV 90 mg day(-1), days 1-21 of a 28-day cycle. Patients were treated in cohorts of three. At the highest dose (irinotecan 180 mg m(-2), oxaliplatin 100 mg m(-2) and UFT 300 mg m(-2) day(-1)), three of four patients experienced grade 3 toxicity. Diarrhoea, lethargy and vomiting were dose-limiting. Three of nine patients had grade 2 toxicities at the maximum tolerated dose (irinotecan 180 mg m(-2), oxaliplatin 100 mg m(-2) and UFT 250 mg m(-2) day(-1)). There were no grade 3 toxicities in the first month of therapy. The overall response rate was 71% in 21 evaluable patients; progression-free survival was 8.8 months. Alternating irinotecan and oxaliplatin plus UFT is an effective and well-tolerated first-line treatment for patients with advanced colorectal cancer. We recommend a dose of irinotecan 180 mg m(-2) on day 1, oxaliplatin 100 mg m(-2) on day 15 and UFT 250 mg m(-2) day(-1) with LV 90 mg day(-1) on days 1-21 of a 28-day cycle for future studies.
