The curability of colon cancer has greatly improved in the past 15 years with the introduction of 5-fluorouracil (5-FU)/leucovorin (LV)-based adjuvant chemotherapy. The last study with a surgery-alone control arm, published by Moertel et al. [1
] in 1990, showed that surgery alone in stages II and III cured 55% of patients whereas the addition of 6 month 5-FU/levamisole improved 3.5-year survival up to 71%. For stage III, these figures for recurrence-free survival were 47% for surgery alone and 63% with adjuvant chemotherapy (P <0.0001). Various regimens have been evaluated since and the bolus 5-FU/LV known as Mayo Clinic has been a reference treatment for years, along with the weekly bolus 5-FU/LV known as Roswell Park. In 2003, the French cooperative group GERCOR [2
] demonstrated that an infusional, 48-h regimen, in combination with LV, had a similar efficacy to the bolus Mayo Clinic regimen, but a better safety
