Eligibility Criteria
DISEASE CHARACTERISTICS: Histologically or cytologically confirmed cancer of the colon or rectum that is locally advanced or metastatic Primary lesion was or is located in the large bowel as confirmed by endoscopy, radiology, or surgery Radiologic or clinical evidence of metastasis subsequent to resection does not require histologic or cytologic confirmation unless: Interval between primary surgery and development of metastasis is greater than 5 years OR Primary cancer was Dukes' A or B1 Ineligible for potentially curative therapy, e.g.: Surgical resection of a limited hepatic or pulmonary metastasis Irradiation of locally recurrent colon or rectal cancer No or minimal symptoms related to the cancer, i.e.: No persistent pain requiring regular narcotic analgesia No persistent fever greater than 38 degrees C No symptomatic bowel obstruction No persistent nausea requiring medication No weight loss of greater than 5 kg over the previous 3 months unless clearly not associated with the cancer (e.g., associated with surgery or intercurrent illness) Symptomatic relapse/metastases rendered asymptomatic by secondary surgery or radiotherapy are eligible provided the patient remains asymptomatic for at least 6 weeks following such treatment No CNS metastases No significant ascites, pleural effusion, or pericardial effusion PATIENT CHARACTERISTICS: Age: Adult under 80 (i.e., of legal age to sign own informed consent according to institutional policy) Performance status: Karnofsky 90-100% ECOG 0 Hematopoietic: Granulocytes at least 1,500/mm3 Platelet count at least 100,000/mm3 Hepatic: Bilirubin no greater than upper limit of normal Renal: Creatinine less than 2.26 mg/dL Cardiovascular: No arrhythmia Other: No infection No other medical condition that is uncontrolled or could be aggravated by the protocol therapy No prior or concurrent second cancer except: Nonmelanomatous skin cancer In situ cervical cancer No pregnant women Adequate contraception required of fertile patients Blood/body fluid analyses to determine eligibility and quality-of-life questionnaire completed within 14 days prior to randomization; imaging studies of sites of disease completed within 28 days prior to randomization PRIOR CONCURRENT THERAPY: Biologic therapy: Not specified Chemotherapy: No prior chemotherapy for metastatic disease or local recurrence Prior fluorouracil-based or other adjuvant therapy allowed At least 6 months required between completion of therapy and documentation of metastasis or recurrence Endocrine therapy: Not specified Radiotherapy: Prior radiotherapy allowed Surgery: Prior surgery allowed
