OUTLINE: Patients receive oxaliplatin IV over 2 hours on day 1, then leucovorin calcium IV over 2 hours with fluorouracil IV bolus, followed by fluorouracil IV over 22 hours on days 1 and 2. Courses repeat every 2 weeks. Patients with stable disease continue treatment in the absence of disease progression or unacceptable toxicity or until disease is resectable. Patients who achieve complete response (CR), partial response (PR) with unresectable disease, or PR but are not surgical candidates continue treatment in the absence of disease progression or unacceptable toxicity. Patients who demonstrate a response are treated until best response or until disease is deemed resectable. Patients who achieve a CR or PR and are resected may receive 2 to 4 additional courses of therapy at the discretion of the investigator. Patients are followed every 3 months for 1 year and then every 6 months for 2 years.
