Randomized comparison of two schedules of fluorouracil and leucovorin in the treatment of advanced colorectal cancer.

Abstract

Intensive-course 5FU plus low-dose leucovorin appears to have a superior therapeutic index compared with weekly 5FU plus high-dose leucovorin using the dosage administration schedules applied in this study based on similar therapeutic effectiveness, but lower financial cost, and less need for hospitalization to manage chemotherapy toxicity.
