Abstract:
PURPOSE:To investigate the hypothesis that a systemic agent designed to inhibit dihydropyrimidine dehydrogenase (DPD), the first enzyme in the fluoropyrimidine degradative pathway, could improve the effective amount of 5-fluorouracil (5-FU) delivered to a tumor resulting in enhanced response. PATIENTS AND METHODS:Eligibility included cytologically or pathologically verified diagnosis of colorectal cancer that recurred during or within 12 months of completion of adjuvant therapy, representing patients generally considered resistant to fluorinated pyrimidine therapy. Stratification was into two cohorts: recurrence while receiving adjuvant therapy, and relapse within 12 months of completing adjuvant therapy. Treatment consisted of 28 days of oral therapy every five weeks with eniluracil and 5-FU administered in a 10:1 ratio. The daily dose of eniluracil was 10 mg/m2 with 5-FU 1 mg/m2, divided into two doses. RESULTS:Twenty-five patients are evaluable for response: 9 relapsed during therapy and 16 relapsed within one year of adjuvant therapy. In the first group, there was one partial response (9%; 95% CI 0-41%); in the second cohort there was one confirmed complete response (5%; 95% CI 0-23%) and one unconfirmed partial response, for an overall response rate of 10%. CONCLUSIONS:This regimen lacks significant activity in this target population. Pre-treatment intratumoral DPD expression was not assessed, therefore the mechanism of fluorinated pyrimidine resistance cannot be specifically attributed to elevated DPD levels. Attempting restoration of chemotherapy sensitivity through blockade of enzymes or signal transduction molecules responsible for resistance is rational, provided that tumor target expression is the basis for trial entry.
