5-Fluorouracil toxicity to the ocular surface epithelium.
The antimetabolite, 5-fluorouracil (5-FU), has been used to control proliferation of retinal pigment epithelial cells and fibrocytes, and is currently the subject of a multicenter clinical trial of its value in the control of scarring after glaucoma operations. To evaluate possible ocular surface toxicity, the effect of 5-FU on the mitotic rate and differentiation of the ocular surface epitheli...
متن کاملToxicity of 5-fluorouracil.
Fluorouracil (5-FU) is a relatively unique drug in oncology because administration in different doses and schedules results in dramatically different patterns of qualitative toxicity. In the 41 years 5-FU has been available to the clinical oncologist, a wide variety of doses and schedules of this agent have been used. Infusional schedules are associated with less myelosuppression but may have m...
متن کاملDihydropyrimidinase deficiency and severe 5-fluorouracil toxicity.
Dihydropyrimidinase (DHP) is the second enzyme in the catabolism of 5-fluorouracil (5FU), and it has been suggested that patients with a deficiency of this enzyme are at risk from developing severe 5FU-associated toxicity. In this study, we demonstrated for the first time that in one patient the severe toxicity, after a treatment with 5FU, was attributable to a partial deficiency of DHP. Analys...
متن کامل5-Fluorouracil toxicity and dihydropyrimidine dehydrogenase enzyme: implications for practice.
5-fluorouracil (5-FU) is a fluorinated pyrimidine analog, which is commonly used in combination chemotherapy for treating solid tumors. Dihydropyrimidine dehydrogenase plays an important role in catabolism and clearance of 5-FU. Any alteration in that sequence of enzymatic activity can lead to toxicity and even death in some patients. The most common loss of a functional allele of the dihydropy...
متن کاملAltered toxicity of 5-fluorouracil following treatment with Corynebacterium parvum.
Recent studies have demonstrated that systemic Corynebacterium parvum increases serum granulocyte-macrophage colony-stimulating factor and stimulates the proliferation of granulocyte-macrophage progenitor cells. It was hypothesized that more rapid cycling of granulocyte-macrophage progenitor cells would render the cells more sensitive to a cell cycle-specific chemotherapeutic agent. The colony-...
