title: 5-Fluorouracil by protracted venous infusion. A review of current progress.
abstract: 5-Fluorouracil (5FU) administered by prolonged intravenous infusion may more effectively treat advanced, slow-growing tumors with low growth fractions and long doubling times. Protracted infusion provides continual cancer cell exposure to 5FU; limitations due to cell cycle specificity and a short plasma half-life are theoretically circumvented. Advances in catheter composition and pump technology now make ambulatory infusion therapy widely available. Clinical trials suggest that prolonged infusion may improve the response rate in colorectal cancer. In addition, preliminary results suggest clinical activity against gastric, pancreatic and refractory breast cancers with minimal toxicity. Despite the potential logistic problems of infusion chemotherapy, many patients report improved quality of life. Increased costs incurred from infusion therapy are probably justifiable if survival is prolonged and quality of life maintained.
