Abstract：
:Forty-eight patients with adenocarcinoma of the gastrointestinal tract were treated on this trial. The MTD of 5-FU given as a 72 hour infusion with high-dose leucovorin was initially determined to be 2000 mg/m2/d. Patients were treated at PALA dose levels ranging from 250 to 2848 mg/m2. Biochemical assessment of target enzyme activity was performed at each PALA dose level. We conclude that compared to each patient's own baseline, PALA at 250 mg/m2 failed to appreciably inhibit ACTase activity at 24 hours in most patients. More consistent inhibition of ACTase activity was seen with PALA at or above 1266 mg/m2, but toxicity was prohibitive with 2848 mg/m2 PALA. Even with the highest PALA doses, ACTase activity was back to baseline by 96 hours in most patients. PALA at 1266 mg/m2 given 24 hours prior to the start of 72 hour infusional 5-FU plus high-dose leucovorin was associated with acceptable toxicity and did not appear to compromise 5-FU dose-intensity. Finally, because of interpatient variability in the degree of ACTase inhibition following PALA, biochemical monitoring of target enzyme activity may permit more rational adjustment of the PALA dose in individual patients.
