RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known which chemotherapy regimen is more effective for colon cancer.

PURPOSE: This randomized phase III trial is studying high-dose fluorouracil with or without leucovorin to see how well it works compared to standard-dose fluorouracil and leucovorin in treating patients who have undergone surgery for stage III colon cancer.

Condition Intervention Phase
Colorectal Cancer Drug: fluorouracil Drug: leucovorin calcium Procedure: adjuvant therapy Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Primary Purpose: Treatment
Official Title: Pan-European Trials in Adjuvant Colon Cancer (PETACC-2): Randomized Phase III Intergroup Trial of High-Dose Infusional 5-FU (+ or - Folinic Acid) Versus Standard Bolus 5-FU/Folinic Acid

Study Start Date: March 1999
Study Completion Date: April 2007
Detailed Description:


  • Compare recurrence-free survival and duration of survival in patients with stage III adenocarcinoma of the colon treated with adjuvant high-dose fluorouracil with or without leucovorin calcium versus standard fluorouracil with leucovorin calcium following curative radical resection.
  • Compare the safety of these regimens in this patient population.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to regional lymph node involvement (N1 (1-3 pericolic lymph nodes) vs N2 (more than 3 pericolic lymph nodes) and participating center.

Patients are randomized to one of two treatment arms.

  • Arm I: Patients receive leucovorin calcium IV followed by fluorouracil IV on days 1-5. Treatment repeats every 4 weeks for 6 courses.
  • Arm II: Patients receive high-dose fluorouracil IV continuously over 48 hours weekly for 8 weeks. Treatment repeats every 8 weeks for 3 courses.


  • Patients receive leucovorin calcium IV over 2 hours followed by fluorouracil IV continuously over 24 hours weekly for 6 weeks. Treatment repeats every 7 weeks for 3 courses.


  • Patients receive leucovorin calcium IV over 2 hours followed by fluorouracil IV bolus and then fluorouracil IV continuously over 22 hours on days 1 and 2. Treatment repeats every 2 weeks for 12 courses.

Patients are followed at 1 month, every 6 months for 4.5 years, and then annually thereafter until death.

PROJECTED ACCRUAL: Approximately 1,600 patients (800 per treatment arm) will be accrued for this study within 3 years.
