5FU, 5-fluorouracil; LV, leucovorin; NS, not significant; NA, not applicable or not reported.

FULV = 5FU 500 mg/m2 + LV 500 mg/m2 bolus weekly for 6 weeks q8 weeks.

FU5LV = LV 200 mg/m2 + 5FU 400 mg/m2 bolus, followed by 5FU 600 mg/m2 22 h infusion day 1 and day 2 q14 days. FOLFOX4 = FU5LV + oxaliplatin 85 mg/m2 day 1 q14 days × 6 months.

mFOLFOX6 = LV 400 mg/m2 + 5FU 400 mg/m2 + oxaliplatin 85 mg/m2 day 1 followed by 5FU 2400 mg/m2 over 46 h q2 weeks. Mayo = 5FU 500 mg/m2 + LV 20 mg/m2 bolus weekly × 30 treatments.

XELOX = capecitabine and oxaliplatin.

a

Includes stage II and III patients. Stage II patients: no overall survival advantage, stage III patients 72.9% vs. 68.7%; p = 0.023.

b

Non-inferiority trial design.

c

For stage III only. Stage II 5-year disease-free survival and overall survival are NS, but pooled stage II + III patients disease-free survival is significant (p = 0.045).

d

No disease-free survival benefit for the addition of bevacizumab.
