    Area of Science:

    • Oncology
    • Pharmacology
    • Cancer Therapeutics

    Context:

    • Fluorinated pyrimidines, including 5-fluorouracil, have been utilized in cancer treatment for over 25 years.
    • Despite extensive clinical application, optimal dosing, administration routes, and schedules are not definitively established.
    • Current treatment adequacy is often defined by objective response or mild toxicity, but dose modifications yield variable outcomes.

    Purpose:

    • To investigate the factors influencing the efficacy and toxicity of fluorinated pyrimidine chemotherapy.
    • To explore the pharmacokinetic behavior of 5-fluorouracil, particularly its persistence in tumor tissue.
    • To identify potential biomarkers or targets for optimizing 5-fluorouracil treatment strategies.

    Summary:

    • 5-fluorouracil exhibits rapid blood clearance but can persist in tumor tissue for extended durations.
