| Sumario: | Cancer is a group of diseases in which abnormal cells grow and divide without control, with the potential to invade other parts of the body. Chemotherapy is a type of treatment that uses chemical agents to treat cancer. These drugs are toxic and produce undesirable adverse drug reactions due to their narrow therapeutic window and highly variable pharmacokinetics, thus, they need to be monitored to establish personalized treatment to achieve maximal efficiency and reduce drug toxicity. Nowadays, therapeutic drug monitoring (TDM) is not routinely used for chemotherapy agents, however, TDM has the potential to improve the clinical benefit of chemotherapy drugs. Tegafur, a prodrug of 5-fluorouracil (5FU), is one of the main anti-cancer drugs used worldwide. Herein, a reproducible and sensitive indirect competitive ELISA has been developed and validated in plasma samples. The assay reports an IC50 of 35.6 nM, reaching a limit of detection of 2.7 nM. It is highly reproducible and does not show cross-reactivity with any related compound. In summary, this assay provides a sensitive, accurate and high throughput analytical method for tegafur quantification in plasma, which fits TDM requirements. © 2017 The Royal Society of Chemistry. |
