    Area of Science:

    • Oncology
    • Gastrointestinal Malignancy Research
    • Pharmacological Studies

    Background:

    • Gastrointestinal malignancies represent a significant health burden.
    • Established chemotherapeutic agents like 5-fluorouracil (5FU), mitomycin C (Mito C), and 1-(2-chloroethyl)-3-(4-methylcyclohexyl)-1-nitrosourea (MeCCNU) have shown activity.
    • Optimizing drug combinations is crucial for improving treatment outcomes.

    Purpose of the Study:

    • To compare the efficacy and tolerability of two drug combinations for gastrointestinal malignancy.
    • Specifically, to evaluate 5-fluorouracil/mitomycin C versus 5-fluorouracil/MeCCNU.

    Main Methods:

    • A comparative study involving 57 patients with evaluable colorectal malignancy.
    • All patients received 5-fluorouracil (5FU) via 24-hour infusion for 5 days every 4 weeks.
    • One group received mitomycin C (Mito C) intravenously every 8 weeks; the second group received MeCCNU orally every 8 weeks.

    Main Results:

    • Both combination regimens were found to be tolerable with acceptable toxicity profiles.
    • The 5-fluorouracil/mitomycin C combination demonstrated a higher response rate of 47%.
    • The 5-fluorouracil/MeCCNU combination achieved a response rate of 25%.

    Conclusions:

    • The combination of 5-fluorouracil and mitomycin C is more efficacious than 5-fluorouracil and MeCCNU for treating colorectal malignancy.
    • These drug combinations offer tolerable treatment options for patients with gastrointestinal cancers.
