Abstract
PURPOSEThis multicenter study compared the therapeutic ratio of a monthly schedule of low-dose leucovorin (LV) and fluorouracil (5-FU) bolus with a bimonthly schedule of high-dose LV and 5-FU bolus plus continuous infusion in patients with advanced colorectal cancer.PATIENTS AND METHODSOf the 448 patients randomly assigned to treatment, 433 were assessable. Treatment A was a monthly regimen of intravenous (IV) LV 20 mg/m2 plus bolus 5-FU 425 mg/m2 for 5 days every 4 weeks. Treatment B was a bimonthly regimen of IV LV 200 mg/m2 as a 2-hour infusion followed by bolus 5-FU 400 mg/m2 and 22-hour infusion 5-FU 600 mg/m2 for 2 consecutive days every 2 weeks. Therapy was continued until disease progression. Second-line chemotherapy, which included 5-FU continuous infusion, was allowed in both arms.RESULTSThe response rates in 348 patients with measurable lesions were 14.4% (monthly regimen) and 32.6% (bimonthly regimen) (P = .0004). The median progression-free survival times were 22 weeks (monthly regimen) and 2...Keywords
