PURPOSE In this study we evaluated the activity and toxicity of a combination of 5-fluorouracil continuous infusion and vinorelbine as second or third line chemotherapy in metastatic breast cancer (MBC). PATIENTS AN METHODS: A total 24 patients who had received doxorrubicin and/or paclitaxel were included in this study. The regimen consisted in 5-fluorouracil 1 gr/m(2) BSA continuous infusion f...

Thirty-six patients with advanced gastrointestinal carcinoma were treated sequentially with full therapeutic doses of l-(2-chloroethyl)-3-cyclohexyl-l-nitrosourea followed by 5-fluorouracil. 5-Fluorouracil could be safely administered at 6 weeks although patients still demonstrated peripheral hematological depression secondary to the earlier l-(2-chloroethyl)-3-cyclohexyl-l-nitrosourea therapy....

A 71-year-old female presented to our hospital with recent increase in diarrhea and body weight loss. Radiologic and endoscopic examinations revealed rectal adenocarcinoma with synchronous multiple liver metastases accompanied by widespread intrabiliary tumor thrombi. After primary tumor resection, systemic treatment using 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX), 5-fluorouracil, le...

Local advanced gastric carcinoma has a very poor prognosis. When a T4 gastric carcinoma has invaded the surrounding tissues and organs, curative resection is unlikely. We present here a case of a 63-year-old woman with a T4 unresectable gastric adenocarcinoma. She underwent two 3-week cycles of docetaxel/cisplatin/fluorouracil chemotherapy, followed by radical gastric resection. Each cycle cons...

An oligodeoxynucleotide duplex containing the chemotherapeutic agent 5-fluorouracil (FU) has been constructed by solid phase phosphotriester synthesis and has been studied in solution by proton NMR. In this study, we provide the first structural characterization of a DNA complex containing a FU.A base pair. It has been determined that the 7-mer duplex containing a central FU.A base pair adopts ...

PURPOSE Patients with advanced gastric or gastroesophageal adenocarcinoma need more efficacious and safer treatments than established today. S-1, a contemporary oral fluoropyrimidine, can provide that advantage. PATIENTS AND METHODS This study was conducted in 24 countries and 146 centers. One thousand fifty-three patients were stratified (center, number of metastatic sites, prior adjuvant th...

BACKGROUND Oral mucositis is one of the most common side-effects of 5-fluorouracil (5-FU)-based chemotherapy. The objective of this study was to evaluate the effects of irsogladine maleate (IM) on fluorouracil-induced oral mucositis through a double-blind, placebo controlled trial. PATIENTS AND METHODS Patients (N = 66) were randomly assigned to receive either placebo or IM (4 mg/day for 14 c...

5-Fluorouracil and 5-fluorodeoxyuridine monophosphate levels were estimated in 75 isolates of Candida albicans to determine whether 5-fluorocytosine susceptibility could be ideally correlated with the intrafungal formation of both 5-fluorodeoxyuridine monophosphate and 5-fluorouridine triphosphate or a reciprocal formation of the two metabolites to prove the mechanism of 5-fluorocytosine activi...

Introduction: Colorectal cancer is the most common malignancy of digestive tract. The treatment based basically on administering antitumor medications, like 5-fluorouracil (5-FU), which belongs to antimetabolites, antineoplastic agents. However, it has been shown that there toxicity related genetic polymorphism in patients treated with 5-FU, including gastrointestinal symptoms, myelosuppression...

Density functional theory (DFT) calculations were performed to investigate the effects of a carbon nanotube (CNT) on the properties of the fluorouracil (F-Uracil) anticancer drug. To achieve the purpose, a molecular model including both of F-Uracil and CNT molecules was created to represent the CNT@F-Uracil compound. The optimized parameters indicated that the new compound could show new proper...
