BACKGROUND While ribavirin mono-therapy regimens have minimal effect on patients with chronic hepatitis C virus (HCV) infections, they can be efficacious when combined with interferon. Clinical studies show that interferon-free combination therapies containing ribavirin are also efficacious, suggesting that an interferon-free therapy could be adopted in the near future. However, generation of d...

BACKGROUND Ocular surface squamous neoplasia (OSSN) is an aggressive eye tumour particularly affecting people with HIV in Africa. Primary treatment is surgical excision; however, tumour recurrence is common. We assessed the effect of fluorouracil 1% eye drops after surgery on recurrence. METHODS We did this multicentre, randomised, placebo-controlled trial in four centres in Kenya. We enrolle...

Abstract New system compromising of chitosan nanoparticles encapsulated pre-synthesized selenium in the presence 5-fluorouracil was successfully prepared and used for cancer antiproliferation. Selenium were synthesized using ascorbic acid as reducing agent under mild condition. Chitosan via ionic gelation technique sodium tri-polyphosphate. Characterization carried out FTIR, TEM, XRD, TGA dynam...

A first derivative spectrometric method has been developed for the determination of the 5-fluorouracil and N1(2'-furanidyl)uracil related substances and degradation products of tegafur. The wavelengths selected for the determination of 5-fluorouracil and N1(2'-furanidyl)uracil were 298 and 288 nm, respectively. At this wavelength, the calibration graphs between the amplitude of the signals and ...

Cardiac toxicity is a widely reported complication of fluoropyrimidine chemotherapies (5-fluorouracil and capecitabine); however, Takotsubo syndrome (TS) is less widely reported. There is little data available describing the viability of fluoropyrimidine rechallenge after fluoropyrimidine-induced TS. We report the case of Ms X, a 41-year-old woman with metastatic oesophageal cancer, who develop...

OBJECTIVE We examined the feasibility of regimen selection for first-line irinotecan, 5-fluorouracil and leucovorin or oxaliplatin, 5-fluorouracil and leucovorin in Japanese patients with advanced colorectal cancer based on UDP-glucuronosyltransferase 1A1 genotype as well as physical status of patients related to diarrhea. METHODS As first-line irinotecan, 5-fluorouracil and leucovorin is a l...

IMPORTANCE Topical fluorouracil was demonstrated to be effective in reducing the number of actinic keratoses (AKs) for up to 6 months, but no randomized trials studied its long-term efficacy. OBJECTIVE To evaluate the long-term efficacy of a single course of fluorouracil cream, 5%, for AK treatment. DESIGN, SETTING, AND PARTICIPANTS The Veterans Affairs Keratinocyte Carcinoma Chemopreventio...

The correlation between 5-fluorouracil-induced resistance to ultraviolet (UV) light and the ability of bacterial cells to repair irradiation damage was investigated in various strains of Escherichia coli. Preincubation with 5-fluorouracil did not influence the dark-repair mechanism. It affected, however, the UV light-induced damage of cell division in filament-forming strains. It is suggested t...
