UFT 300 mg/m2/d plus oral leucovorin 150 mg/d administered for 28 days demonstrated significant activity against metastatic colorectal carcinoma. This oral regimen was well tolerated and devoid of the neutropenia or significant oral mucositis that complicates intravenous schedules of fluorouracil (5-FU) plus leucovorin. The results of this clinical trial will serve as the basis for a randomized phase III study to compare this oral schedule of UFT plus leucovorin with intravenous 5-FU plus leucovorin to determine the relative efficacy, impact on quality of life, and cost of the two regimens.
Single-agent capecitabine in patients with metastatic colorectal carcinoma refractory to FU showed no objective responses and clinical benefit that was, at best, modest. The use of capecitabine in combination with other treatments in this patient population is under investigation.
Administered at the stated dose and schedule, docetaxel has little activity against metastatic colorectal carcinomas. The toxicity profile, consisting of granulocytopenia, hypersensitivity reactions, cutaneous reactions, and edema, has been previously described in patients receiving docetaxel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
