Résumé
Date de début de l'étude : 1 juin 1995
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: I. Compare the survival and quality of life of patients with metastatic or recurrent colorectal cancer receiving palliative therapy with leucovorin/fluorouracil vs. continuous-infusion fluorouracil vs. ICI D1694. II. Compare the survival and quality of life of patients with stable or responding disease after 12 weeks of initial treatment randomized to receive 12 additional weeks of chemotherapy vs. no further treatment. OUTLINE: This is a randomized study. Patients are stratified by participating institution. Patients are randomized to one of three treatment regimens. The first group receives leucovorin followed by fluorouracil every 14 days for a total of 6 courses. The second group receives continuous-infusion fluorouracil for 12 weeks. The third group receive ICI D1694 every 21 days for a total of 4 courses. Patients without progressive disease or excessive toxicity after 12 weeks of treatment are then randomized to receive continuing chemotherapy in 12 weekly cycles of their assigned chemotherapy or to proceed to observation with no further therapy, until evidence of disease progression. Patients are followed every 6 weeks. PROJECTED ACCRUAL: A total of 900 patients will be entered.
