  1. Compare the disease-free survival of patients with completely resected stage IIB or III colon cancer treated with adjuvant chronomodulated vs standard schedule fluorouracil and leucovorin calcium with or without carboplatin.
  2. Compare the overall survival of patients treated with these regimens.
  3. Compare the toxicity of these regimens in these patients.
  4. Compare the quality of life of patients treated with these regimens.
  5. Determine the dose intensities of fluorouracil and carboplatin in these patients.

Primary Outcome(s)

Disease-free survival

Secondary Outcome(s)

Quality of life


This is a randomized, multicenter study. Patients are stratified according to participating center and disease stage (IIB vs III). Patients are randomized to 1 of 4 treatment arms.

  • Arm I (standard schedule): Patients receive fluorouracil (5-FU) IV continuously and leucovorin calcium (CF) IV on days 1 and 2.
  • Arm II (standard + carboplatin schedule): Patients receive 5-FU and CF as in arm I plus carboplatin IV on day 1.
  • Arm III (chronomodulated schedule): Patients receive 5-FU IV continuously and CF IV continuously on days 1-4.
  • Arm IV (chronomodulated + carboplatin schedule): Patients receive 5-FU and CF as in arm III plus carboplatin IV continuously on days 1-4.

Quality of life is assessed.

Treatment in all arms repeats every 14 days for up to 9 courses in the absence of disease progression or unacceptable toxicity.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
