PURPOSE: To investigate whether infusional high-dose 5-flurouracil (HD-FU) provides a significant improvement in recurrence-free survival (RFS) and overall survival (OS) compared with a standard bolus 5-FU regimen (Mayo Clinic) in patients with curatively resectable stage III colon cancer.
METHODS: Patients (n=1601) were randomised to receive either the Mayo Clinic regimen or one of the three HD-FU regimens; LV5FU2, the Arbeitsgemeinschaft Internistische Onkologie (AIO) or the Grupo Espaňol para el Tratamiento Digestivos (TTD), the data from which were combined to provide the HD-FU arm for final analysis.
RESULTS: Patients were evenly balanced for age, TMN, tumor grade and vascular and lymphatic invasion. Median follow-up was approximately 42months, RFS (hazard ratio [HR]=0.997) and OS (HR=0.96) (primary end-point) were not statistically different between the two treatment arms. Infusional HD-FU was generally better tolerated than bolus 5-FU regimen.
CONCLUSIONS: Infusional HD-FU does not improve RFS and OS in curatively resected stage III colon cancer patients compared to the Mayo Clinic regimen, but is less toxic.
