OBJECTIVE To examine clinical and molecular changes after topical fluorouracil treatment of photodamaged human facial skin for actinic keratoses. DESIGN Nonrandomized, open-label 2-week treatment with fluorouracil cream, 5%, followed by clinical and molecular evaluation. SETTING Academic referral center. PATIENTS Twenty-one healthy volunteers, 56 to 85 years old, with actinic keratoses an...

CONTEXT 5-fluorouracil (5-FU) is an antimetabolite that acts during the S phase of the cell cycle. Dihydropyrimidine dehydrogenase (DPD) is the initial and rate-limiting enzyme in the pathway that catabolises the pyrimidines. 5-fluorouracil and its oral prodrug capecitabine are used in the treatment of a number of solid tumors, including colorectal, breast, gastric, pancreatic, prostate, and bl...

OBJECTIVE In Japan, cisplatin/5-fluorouracil 80/800 (cisplatin 80 mg/m2, 5-fluorouracil 800 mg/m2) is widely used to treat recurrent/metastatic squamous cell carcinoma of the head and neck, whereas cisplatin/5-fluorouracil 100/1000 (1000 mg/m2/24 h by continuous intravenous infusion on Days 1-4 plus cisplatin 100 mg/m2 on Day 1 in 3-week cycles) is the standard treatment in Europe and North Ame...

Exposure of L1210 leukemia cells first to 0.1 to 100 micromolar methotrexate and then to 10 micromolar 5-fluorouracil produces a synergistic effect on the number of cells killed in culture. Methotrexate dose-related increases occur in the concentrations of intracellular 5-fluorouracil ribonucleotides and 5-fluoro-2'-deoxyuridylate and in the incorporation of 5-fluorouracil into RNA. These incre...

BACKGROUND Capecitabine is an oral prodrug of 5-fluorouracil and has been studied for the treatment of colorectal cancer. In 2 Phase III trials, capecitabine was at least as effective as 5-fluorouracil plus leucovorin and had a more favorable toxicity profile. OBJECTIVE A cost-benefit analysis was used to assess the pharmacoeconomic profile of capecitabine compared with 5-fluorouracil/leucovo...

A case of hyperammonaemic encephalopathy that developed during the administration of a widely used chemotherapy regimen is reported in a 51-year-old man. 5-Fluorouracil was considered to be the causative agent. Although encephalopathy is a rare toxic effect of 5-fluorouracil, this case illustrates a serious and potentially life-threatening complication during a chemotherapy regimen using 5-fluo...

BACKGROUND Severe cardiotoxicity is a documented, but very unusual side-effect of intravenous 5-fluorouracil therapy. The mechanism producing cardiotoxicity is poorly understood. CASE PRESENTATION A case of 5-fluorouracil-induced cardiotoxicity, possibly due to coronary artery spasm, and mimicking acute anterolateral myocardial infarction is presented and discussed. Electrocardiographs highli...

The purpose of this study was to explore the effect of trastuzumab in enhancing the activity of chemotherapeutic agents and the molecular basis of this effect. Two gastric cancer cell types with HER2 amplification, one sensitive (NCI‑N87) and one insensitive (MKN-7) to trastuzumab, were tested for the effects of trastuzumab on cell growth and cell signaling using MTS assay and western blotting,...
